An appropriate level of risk perception should be a critical issue in modern "risk society." There have been many studies on the influences on risk perception. This study investigates whether risk communication scholar Dr. Peter Sandman's outrage factors intensify journalistic attention to health risks from food consumption. A content analysis of a health institution's press releases was conducted to examine 15 outrage factors of food risks conveyed in the governmental risk communication. In addition, the news stories covering the food risks informed by the press releases were calculated to evaluate the relation between outrage factors of a risk and the number of news stories covering the risk. Results showed that controllability was the most salient outrage factor, followed by trust, voluntariness, familiarity, and human origin; the greater the outrage score of a risk, the more news stories of the risk. For individual outrage factors, a risk with an implication of catastrophic potential was associated with an increase of news stories. Food providers' distrustful behaviors also influenced journalistic attention to the food risks. The implication of the findings to health message designers is discussed.

Full Text Available Food insecurity is a major challenge for Niger and for many African countries. The purpose of this study is to investigate the factors affecting household food security in Niger. Based on survey data covering 500 households, drought, high food prices, poverty, soil infertility, disease and insect attacks are reported by the respondents to be the main causes of food insecurity. The empirical results from logistic regression revealed that the gender of the head of household, diseases and pests, labor supply, flooding, poverty, access to market, the distance away from the main road and food aid are significant factors influencing the odds ratio of a household having enough daily rations. Another important finding is that female headed households are more vulnerable to food insecurity compared to male headed households. The findings of this study provide evidence that food insecurity continues to affect the Nigerien population.

Nutritional knowledge as well as economic, social, biological, and cultural factors have been known to determine an individual's food choices. Despite the existence of research on the factors which influence nutrition globally, there is little known about the extent to which these factors influence the food choices of construction workers, which in turn influence their health and safety during construction activities. The present article investigates the extent to which construction workers' nutrition is influenced by nutritional knowledge, as well as economic, environmental, social, psychological, and physiological factors. A field questionnaire survey was conducted on site construction workers in the Gauteng Province of South Africa. Principal components analysis and multiple regression analysis were used to analyze the data. Findings revealed that consumption of foods termed alternative foods including dairy products, eggs, nuts, fish, and cereals, was influenced by nutritional knowledge and resources. Foods termed traditional core foods were influenced by cultural background; foods termed secondary core foods comprising fruits and vegetables were influenced by economic factors, resources, and cultural background; while foods termed core foods were mostly influenced by nutritional knowledge. By providing evidence of the factors which most influence selection and consumption of certain foods by construction workers, relevant nutrition interventions will be designed and implemented, taking cognizance of these factors.

Full Text Available The global markets have witnessed major shifts in the consumers’ behavior that have been much influenced by the change of technology, innovation, research and development. The consumer’s needs thus dynamically change in order to respond to the change in the social and business environment. The corporate and business strategies of companies thus being developed in the light of capitalizing the potential from the markets but however, how the customers would react to the products and services of companies in new and existing markets remain the major question. Customers belonging to different age groups flock towards these outlets to satisfy their taste buds and hedonistic needs. Out of all the age groups, the youngsters are considered to be the primary target by the fast food service industry. Hence, these fast food services try to lure its customers through sensory appeals. It is well known that organized fast food services have already made their presence felt in a big way in almost all the major cities of India. The fast food outlets attract customers with their blend of tasty food, Quality of food served, efficient service, the appearance of staff, décor, general excitement a place generates and other aesthetic appeals. Organized as well as unorganized fast food service is a very fast growing industry in India especially in urban areas.  The aim of this study is to investigate the factors that are influencing consumer behavior towards fast food joints present in unorganised form in India. It further aims to examine major growth drivers of fast food services in the market and the demographic profile of consumers of fast food services. This study aims to analyze that amount spent per visit to a fast food joint relates to the occupations and the income of customers. And the frequency of visiting fast food joints and preparation served at fast food joints are whether influenced by the dietary preference of customers. Organizations must

To assess food safety practices, food shopping preferences, and eating behaviors of people diagnosed with Salmonella or Campylobacter infection in the warm seasons, and to identify socioeconomic factors associated with behavior and practices. A cross-sectional survey was conducted among Salmonella and Campylobacter cases with onset of illness from January 1 to March 31, 2013. Multivariable logistic regression analyses examined relationships between socioeconomic position and food safety knowledge and practices, shopping and food preferences, and preferences, perceptions, and knowledge about food safety information on warm days. Respondents in our study engaged in unsafe personal and food hygiene practices. They also carried out unsafe food preparation practices, and had poor knowledge of foods associated with an increased risk of foodborne illness. Socioeconomic position did not influence food safety practices. We found that people's reported eating behaviors and food preferences were influenced by warm weather. Our study has explored preferences and practices related to food safety in the warm season months. This is important given that warmer ambient temperatures are projected to rise, both globally and in Australia, and will have a substantial effect on the burden of infectious gastroenteritis including foodborne disease. Our results provide information about modifiable behaviors for the prevention of foodborne illness in the household in the warm weather and the need for information to be disseminated across the general population. An understanding of the knowledge and factors associated with human behavior during warmer weather is critical for public health interventions on foodborne prevention.

Polyphenols: factors influencing their sensory properties and their effects on food and beverage preferences.

Lesschaeve, Isabelle; Noble, Ann C

Bitterness and astringency are found in a variety of foods, including nuts, fruits, chocolate, tea, wine, and soymilk. In fruits and beverages, the taste of bitterness and the tactile sensation of astringency are elicited primarily by flavanol polymers (proanthocyanidins or condensed tannins). Variations in proanthocyanidin composition, such as polymer size, extent of galloylation, and formation of derivatives, affect both bitterness and astringency. In beverages, other factors also influence these sensations, including the pH and the levels of ethanol, sweetness, and viscosity. Similarly, foods eaten with beverages can influence astringency. For example, eating dark chocolate increases the astringency of red wine more than does milk chocolate. Individuals perceive astringency differently because of variations in salivary flow rates, and preferences for and acceptance of a product may vary tremendously among individuals; decreasing bitterness and/or astringency may not increase preference. Factors influencing bitterness, astringency, and individual preference decisions are discussed.

Breakfast consumption has been shown to be an important indicator of a healthy lifestyle. Little is known however about factors influencing breakfast consumption and food choices at breakfast in adolescents. The aim of the present study was therefore to describe breakfast habits, and factors influencing food choices at breakfast within the framework of the EU-funded HELENA Study, in 3528 adolescents from ten European cities. Additionally, socio-demographic differences in breakfast habits and in influencing factors were investigated. Half of the adolescents (and fewer girls than boys) indicated being regular breakfast consumers. Girls with mothers with a high level of education, boys from 'traditional' families and boys who perceived low family affluence were positively associated with breakfast consumption. Boys whose parents gave encouragement and girls whose peers ate healthily were more likely to be regular breakfast consumers. 'Hunger', 'taste', 'health concerns' and 'parents or guardian' were the most important influences on the adolescents' food choices at breakfast. Adolescents from southern Europe and girls reported to be more influenced by personal and socio-environmental factors. Socio-demographic differences, in particular regional and gender differences, need to be considered in discussions surrounding the development of nutritional intervention programs intended for adolescents.

2010-11-01

Food safety training has been the primary avenue for ensuring food workers are performing proper food handling practices and thus, serving safe food. Yet, knowledge of safe food handling practices does not necessarily result in actual performance of these practices. This research identified participating food service employees' level of agreement with four factors of motivation (internal motivations, communication, reward-punishment, and resources) and determined if respondents with different demographic characteristics reported different motivating factors. Data were collected from 311 food service employees who did not have any supervisory responsibilities. Intrinsic motivation agreement scores were consistently the highest of all four motivational factors evaluated and did not differ across any of the demographic characteristics considered. In contrast, motivation agreement scores for communication, reward-punishment, and resources did differ based on respondents' gender, age, place of employment, job status, food service experience, completion of food handler course, or possession of a food safety certification. In general, respondents agreed that these motivation factors influenced their likelihood to perform various safe food handling procedures. This research begins to illustrate how employees' demographic characteristics influence their responses to various motivators, helping to clarify the complex situation of ensuring safe food in retail establishments. Future research into why employee willingness to perform varies more for extrinsic motivation than for intrinsic motivation could assist food service managers in structuring employee development programs and the work environment, in a manner that aids in improving external motivation (communication, reward-punishment, and resources) and capitalizing on internal motivation.

Smith, Teresa M; Dunton, Genevieve F; Pinard, Courtney A; Yaroch, Amy L

2016-04-01

The purpose of the present study was to explore food preparation behaviours, attitudes, meal planning and shopping among Mexican-American mothers. Data were collected through four focus groups with mothers of Mexican origin/ancestry who considered themselves to be the primary food preparer. Topics included food preparation behaviours and influencers (culture, family, attitudes, barriers, meal planning and shopping). Data were analysed using a qualitative grounded theory approach. All focus groups were audio recorded, transcribed verbatim and coded for themes. Data were collected in southern California, USA in 2013. Of the sample of twenty-one Mexican-American mothers, thirteen were born outside the USA and the mean household size was five members. Participants reported that food was often prepared using traditional staples and food preparation behaviours were learned from maternal family members. Participants also suggested that health was influenced by foods eaten and how they were prepared. Salient factors influencing food preparation behaviours included culture and tradition, maternal family members' food preparation behaviours, food preparation self-efficacy and attitudes towards healthy eating. Time and busy schedules were cited as barriers. Future interventions should consider utilizing family-based approaches and teaching culturally relevant food preparation skills, especially to youth, while reinforcing more healthful dietary practices.

Full Text Available Abstract Background Very little is known about street food and fast food consumption patterns in South Africa despite this being a large sector of the national economy in terms of employment provided and sales of food. The objective of this study was to determine the use of street foods and fast foods purchased by South Africans living in different provinces and geographic areas. Methods A cross-sectional survey was conducted. Structured interview-administered questionnaires in 11 official languages were conducted at the participants' homes. A nationally representative sample (n = 3287 was drawn from all ethnic groups, and provinces including participants 16 years and older. Logistic regression was done to evaluate factors impacting on fast food consumption. Results Frequent (2 ≥ times/week street food consumption ranged from 1.8% in Northern Cape to 20.6% in Limpopo; frequent (2 ≥ times/week fast food consumption ranged between 1.5% in North West Province to 14.7% in Gauteng. The highest intake of street food was in the medium socio-economic category (14.7% while the highest intake of fast foods was in the high socio-economic category (13.2%. Overall, fruit was the most commonly purchased street food by all ethnic groups over the previous week although this practice was highest in black participants (35.8%. Purchases of soft drinks ranged from 4.8% in whites to 16.4% in blacks and savoury snacks from 2.3% to 14.5% in whites and blacks, respectively. Consumption of fast foods and street foods were influenced by a number of socio-demographic factors including ownership of major home appliances. Frequent fast food consumers had a significantly higher dietary diversity score (4.69; p Conclusions A large percentage of the population purchase street foods and fast foods. This is of some concern when one notes the high prevalence of soft drink consumption in terms of its association with obesity and non-communicable diseases. These findings need

2015-01-01

Influential factors on food risk perception were investigated from the viewpoints of socio-demographics, lifestyles and personalities. The anxieties about 24 types of food based on six product areas and four food types were investigated through the questionnaire survey getting 16,650 respondents in Japan. Besides, 60 questions were prepared to investigate the personalities based on 14 sub-scales. The anxiety was influenced mainly by the product areas instead of food types; the highest anxiety was observed for the foods from China, followed by those from developing countries (except for China), developed countries, and Fukushima. For personality, nine factors were extracted. The results of multiple regression analysis incorporating socio-demographic, lifestyle, and personality variables were not influenced by the food types but influenced by the product areas. The most influential variable on the anxiety for all product areas was 'habits to check product areas.' It was also indicated that 'general trust' and 'being strict in discipline' were most influential personalities on the anxiety about foods from Fukushima and foods from China, respectively. (author)

BACKGROUND/OBJECTIVES The purpose of this study is to identify how level of information affected intention, using the Theory of Planned Behavior. SUBJECTS/METHODS The study was conducted survey in diverse community centers and shopping malls in Seoul, which yielded N = 209 datasets. To compare processed foods consumption behavior, we divided samples into two groups based on level of information about food additives (whether respondents felt that information on food additives was sufficient or not). We analyzed differences in attitudes toward food additives and toward purchasing processed foods, subjective norms, perceived behavioral control, and behavioral intentions to processed foods between sufficient information group and lack information group. RESULTS The results confirmed that more than 78% of respondents thought information on food additives was insufficient. However, the group who felt information was sufficient had more positive attitudes about consuming processed foods and behavioral intentions than the group who thought information was inadequate. This study found people who consider that they have sufficient information on food additives tend to have more positive attitudes toward processed foods and intention to consume processed foods. CONCLUSIONS This study suggests increasing needs for nutrition education on the appropriate use of processed foods. Designing useful nutrition education requires a good understanding of factors which influence on processed foods consumption. PMID:24944779

Full Text Available Internet marketing plays an important role on profitability of organizations, it can build a bridge between customers and business owners and anyone could purchase products and services through internet. In this paper, we present an empirical investigation to detect important factors influencing internet marketing on Iranian food industry, named Shahrvand. The proposed study selects 280 out of 1040 managers who were involved in this industry during the year of 2012. Structural equation modeling has been performed to detect important factors including internal/external factors, ease of use and electronic marketing. Cronbach alphas have been calculated for these four items were mostly above 0.80, which validated the overall questionnaire of the survey. The results indicate that among internal factors, knowledge management, organizational culture and resources influence on acceptance of internet marketing, while these factors do not show any meaningful impact on ease of use. In addition, external factors including trend on market growth, competition and infrastructure influence on ease of use and acceptance of internet marketing but infrastructure and competition do not impact on ease of internet marketing.

Lebersorger, S; Schneider, F

2014-11-01

This paper quantifies food loss rates for fruit & vegetables, dairy products and bread & pastry as well as donations to social services. In addition potential influencing factors and reasons for food losses are investigated in order to provide a basis for the development of waste prevention measures. Detailed data from 612 retail outlets all over Austria, which covered the period of one year, were analysed and sorting analyses of discarded food were carried out in a small sample of retail outlets. Food loss amounts to 1.3% of the sales of dairy products, 2.8% for bread & pastry and 4.2% for fruit & vegetables. Returned bread amounts to additional 9.7% of the sales of bread & pastry. The food loss rates are similar to the results of previous publications. At present, 7% of the food loss is donated to social services, 38% of retail outlets do not donate any articles at all. Food loss rates are declining with increasing sales areas, increasing numbers of purchases per year and increasing sales of the retail outlet, but explain only 33% or less of the variation of food loss rates. Large differences between retail outlets of comparable structure indicate potential for reduction. More than a quarter of discarded food articles did not show any flaws besides the expiration of the best before or sell-by date. Waste prevention approaches should focus on avoiding returns, transfer of best practices, information and education of employees and customers as well as strengthening the donation to social services.

The aim of this study was to assess, by means of an original video approach, the influence of the environment on food intake in nursing homes. Methods: The perception of the environment during meals in nursing homes was evaluated by residents and by two groups of volunteers who either work in the field of geriatrics, or who do not work in the field of geriatrics. First, a random sample of residents answered a self-administered questionnaire related to different indicators (ie, noise, space, comfort, light, odors, perceived satisfaction of meals, taste of meals, presentation of meals, service and setting. Second, two separate panels, one including the people who work in the field of geriatrics (ie, experts and one including the people who have no particular interest in geriatrics (ie, nonexperts, were asked to answer a questionnaire on their perception of the environment after having watched a video of the lunch in each nursing home. Then, the food intake of the residents was measured by a precise food-weighing method. Results: A total of 88 residents from nine different nursing homes, 18 experts and 45 nonexperts answered the questionnaires.

The goal of this concise narrative review is to examine the current literature regarding endogenous and exogenous influences on youth food choices. Specifically, we discuss internal factors such as interoception (self-awareness) of pain and hunger, and neural mechanisms (neurofunctional aspects) of food motivation. We also explore external factors such as early life feeding experiences (including parenting), social influences (peers), and food marketing (advertising). We conclude with a discussion of the overlap of these realms and future directions for the field of pediatric food decision science. Copyright © 2015 Elsevier Ltd. All rights reserved.

2015-01-01

Foodborne disease is a significant problem worldwide. Research exploring sources of outbreaks indicates a pronounced role for food workers' improper health and hygiene practice. To investigate food workers' perceptions of factors that impact proper food safety practice. Interviews with food service workers in Baltimore, MD, USA discussing food safety practices and factors that impact implementation in the workplace. A social ecological model organizes multiple levels of influence on health and hygiene behavior. Issues raised by interviewees include factors across the five levels of the social ecological model, and confirm findings from previous work. Interviews also reveal many factors not highlighted in prior work, including issues with food service policies and procedures, working conditions (e.g., pay and benefits), community resources, and state and federal policies. Food safety interventions should adopt an ecological orientation that accounts for factors at multiple levels, including workers' social and structural context, that impact food safety practice.

Liking food less: the impact of social influence on food liking evaluations in female students.

Eric Robinson

Full Text Available Social factors are known to influence food intake and choice. However, whether social influence acts on evaluations of food and drink liking has not been studied. Across two studies, we tested whether leading a participant to believe that other people do not like a food affects food liking evaluations. In Study 1, we exposed participants to social normative information suggesting a that an in-group disliked orange juice, b that an out-group disliked orange juice or c that an in-group were neutral about orange juice. We then examined how much participants believed they liked orange juice. In Study 2, participants consumed a snack food before being led to believe that two previous participants had also eaten the food and either disliked or quite liked it. We asked participants to rate how much they had enjoyed eating the snack food. Across both studies, social influence was observed, as underlined by decreases in liking evaluations. In Study 1, beliefs about liking were only influenced by social normative information when the norm was expressed by an in-group. In Study 2, exposure to others' accounts of a negative experience with a food decreased evaluated liking of the recent consumption experience. These results suggest that social influence can act upon food liking evaluations.

Social factors are known to influence food intake and choice. However, whether social influence acts on evaluations of food and drink liking has not been studied. Across two studies, we tested whether leading a participant to believe that other people do not like a food affects food liking evaluations. In Study 1, we exposed participants to social normative information suggesting a) that an in-group disliked orange juice, b) that an out-group disliked orange juice or c) that an in-group were neutral about orange juice. We then examined how much participants believed they liked orange juice. In Study 2, participants consumed a snack food before being led to believe that two previous participants had also eaten the food and either disliked or quite liked it. We asked participants to rate how much they had enjoyed eating the snack food. Across both studies, social influence was observed, as underlined by decreases in liking evaluations. In Study 1, beliefs about liking were only influenced by social normative information when the norm was expressed by an in-group. In Study 2, exposure to others' accounts of a negative experience with a food decreased evaluated liking of the recent consumption experience.

The aim of this study was to identify psychosocial factors that influence fast-food consumption in urban and rural Costa Rican adolescents. A self-administered questionnaire designed for the study asked about sociodemographic information, frequency of fast-food consumption, meaning of "fast food," location of purchase, and psychosocial correlates. Five psychosocial factors were extracted by using principal components analysis with Varimax rotation method and eigenvalues. Descriptive statistics and a hierarchical linear regression model were used to predict the frequency of fast-food consumption. Responses from 400 adolescents (ages 12-17 y) reveal that daily consumption of fast food was 1.8 times more frequently mentioned by rural adolescents compared with urban youth. Urban and rural differences were found in the way adolescents classified fast foods (rural adolescents included more traditional foods like chips, sandwiches, and Casado-a dish consisting of rice, black beans, plantains, salad, and a meat), and in purchasing locations (rural adolescents identified neighborhood convenience stores as fast-food restaurants). Living in rural areas, convenience and availability of foods, and the presence of external loci of control were predictors of a higher frequency of fast-food consumption, whereas health awareness predicted a lower frequency. The development of interventions to reduce fast-food consumption in Costa Rican adolescents should consider not only convenience, but also the availability of these foods where adolescents are more exposed, particularly in rural areas. Interventions such as improving the convenience of healthy fast foods available in school canteens and neighborhood stores, policies to increase the price of unhealthy fast food, and activities to provide adolescents with the skills to increase self-efficacy and reduce the effect of external loci of control are recommended.

Wise, Nancy J

2015-01-01

Healthy eating among pregnant adolescents is essential for the well-being of developing adolescent females and their fetuses, as well as for the prevention of adult chronic illness. Understanding factors that influence and prohibit healthy eating, along with preferences for nutrition education in the pregnant adolescent population, is critical when designing and implementing appropriate nutrition education programs. The purpose of this study was to collect individual viewpoints of pregnant adolescents to facilitate the development of a nutrition intervention. This qualitative study using focus group methodology was conducted among pregnant adolescents. Participants (N = 14) were recruited through and teen parenting programs in the Mid-Atlantic region. Focus groups were guided by 6 open-ended questions that were developed based on implications from a previous study that surveyed eating habits of pregnant adolescents. Data were analyzed and coded using verbatim transcripts. Transcripts were read carefully for overall content and identification of major categories and then compared for similar and contrasting data. Four recurring themes emerged that described beliefs about healthy eating, influences on food choices, and nutrition education preferences: 1) pregnant adolescents demonstrate overall knowledge of healthy foods but are unwilling to give up unhealthy foods; 2) parents, offspring, and pregnancy influence healthy eating habits; 3) pregnant adolescents choose foods based on appearance and taste, cravings, convenience, and cost; and 4) pregnancy alters eating habits. Nutrition education in this population should be peer- and adolescent-focused and incorporate preferred methods of learning and favored incentives. Pregnant adolescents are more likely to attend educational programs that are population-specific and peer-focused, and include incentives that make cooking easier, more convenient, and affordable. Program content should be available to potential

Systematic reviews investigating associations between objective measures of the food environment and dietary behaviours or health outcomes have not established a consistent evidence base. The present paper aims to synthesise qualitative evidence regarding the influence of local food environments on food and purchasing behaviours. A systematic review in the form of a qualitative thematic synthesis. Urban localities. Adults. Four analytic themes were identified from the review including community and consumer nutrition environments, other environmental factors and individual coping strategies for shopping and purchasing decisions. Availability, accessibility and affordability were consistently identified as key determinants of store choice and purchasing behaviours that often result in less healthy food choices within community nutrition environments. Food availability, quality and food store characteristics within consumer nutrition environments also greatly influenced in-store purchases. Individuals used a range of coping strategies in both the community and consumer nutrition environments to make optimal purchasing decisions, often within the context of financial constraints. Findings from the current review add depth and scope to quantitative literature and can guide ongoing theory, interventions and policy development in food environment research. There is a need to investigate contextual influences within food environments as well as individual and household socio-economic characteristics that contribute to the differing use of and views towards local food environments. Greater emphasis on how individual and environmental factors interact in the food environment field will be key to developing stronger understanding of how environments can support and promote healthier food choices.

Factors affecting food security and contribution of modern technologies in food sustainability.

The concept of food insecurity is complex and goes beyond the simplistic idea of a country's inability to feed its population. The global food situation is redefined by many driving forces such as population growth, availability of arable lands, water resources, climate change and food availability, accessibility and loss. The combined effect of these factors has undeniably impacted global food production and security. This article reviews the key factors influencing global food insecurity and emphasises the need to adapt science-based technological innovations to address the issue. Although anticipated benefits of modern technologies suggest a level of food production that will sustain the global population, both political will and sufficient investments in modern agriculture are needed to alleviate the food crisis in developing countries. In this globalised era of the 21st century, many determinants of food security are trans-boundary and require multilateral agreements and actions for an effective solution. Food security and hunger alleviation on a global scale are within reach provided that technological innovations are accepted and implemented at all levels.

Blissett, Jackie; Fogel, Anna

2013-09-10

The foods that tend to be rejected by children include those which may have greatest importance for later health. This paper reviews some of the intrinsic and extrinsic influences on preschool children's eating behavior, with particular reference to their acceptance of new foods into their diet. Factors conceptualized as intrinsic to the child in this review include sensory processing, taste perception, neophobia, and temperament. The important extrinsic determinants of children's food acceptance which are reviewed include parental and peer modeling, the family food environment, infant feeding practices including breastfeeding and age at weaning, concurrent feeding practices including restriction, pressure to eat, prompting and reward, and the taste & energy content of foods. Children's willingness to accept new foods is influenced by a wide range of factors that likely have individual and also interactive effects on children's willingness to taste, and then continue to eat, new foods. The literature lacks longitudinal and experimental studies, which will be particularly important in determining interventions most likely to be effective in facilitating children's acceptance of healthy foods.

Family environmental factors influencing the developing behavioral controls of food intake and childhood overweight.

Science.gov (United States)

Birch, L L; Davison, K K

2001-08-01

Although a large body of research has assessed direct genetic links between parent and child weight status, relatively little research has assessed the extent to which parents (particularly parents who are overweight) select environments that promote overweight among their children. Parents provide food environments for their children's early experiences with food and eating. These family eating environments include parents' own eating behaviors and child-feeding practices. Results of the limited research on behavioral mediators of familial patterns of overweight indicate that parents' own eating behaviors and their parenting practices influence the development of children's eating behaviors, mediating familial patterns of overweight. In particular, parents who are overweight, who have problems controlling their own food intake, or who are concerned about their children's risk for overweight may adopt controlling child-feeding practices in an attempt to prevent overweight in their children. Unfortunately, research reveals that these parental control attempts may interact with genetic predispositions to promote the development of problematic eating styles and childhood overweight. Although the authors have argued that behavioral mediators of family resemblances in weight status, such as parents' disinhibited or binge eating and parenting practices are shaped largely by environmental factors, individual differences in these behaviors also have genetic bases. A primary public health goal should be the development of family-based prevention programs for childhood overweight. The findings reviewed here suggest that effective prevention programs must focus on providing anticipatory guidance on parenting to foster patterns of preference and food selection in children more consistent with healthy diets and promote children's ability to self-regulate intake. Guidance for parents should include information on how children develop patterns of food intake in the family context

Full Text Available Early feeding of free sugars to young children can increase the preference for sweetness and the risk of consuming a cariogenic diet high in free sugars later in life. This study aimed to investigate early life factors influencing early introduction of foods/drinks containing free sugars. Data from an ongoing population-based birth cohort study in Australia were used. Mothers of newborn children completed questionnaires at birth and subsequently at ages 3, 6, 12, and 24 months. The outcome was reported feeding (Yes/No at age 6–9 months of common foods/drinks sources of free sugars (hereafter referred as foods/drinks with free sugars. Household income quartiles, mother’s sugar-sweetened beverage (SSB consumption, and other maternal factors were exposure variables. Analysis was conducted progressively from bivariate to multivariable log-binomial regression with robust standard error estimation to calculate prevalence ratios (PR of being fed foods/drinks with free sugars at an early age (by 6–9 months. Models for both complete cases and with multiple imputations (MI for missing data were generated. Of 1479 mother/child dyads, 21% of children had been fed foods/drinks with free sugars. There was a strong income gradient and a significant positive association with maternal SSB consumption. In the complete-case model, income Q1 and Q2 had PRs of 1.9 (1.2–3.1 and 1.8 (1.2–2.6 against Q4, respectively. The PR for mothers ingesting SSB everyday was 1.6 (1.2–2.3. The PR for children who had been breastfed to at least three months was 0.6 (0.5–0.8. Similar findings were observed in the MI model. Household income at birth and maternal behaviours were significant determinants of early feeding of foods/drinks with free sugars.

Indian adolescents' over reliance on foods such as nutrient-poor snacks, sugar-sweetened beverages and take-away foods puts them at significant risk of obesity and several diet-related chronic diseases. Therefore, the factors that influence their dietary behaviours need to be better understood in order to develop effective nutrition promotion strategies. The purpose of this qualitative inquiry was to investigate adolescents', parents', teachers', and school principals' perceptions of the main influences on adolescent eating behaviours. Fifteen adolescents aged 14-15 years, 15 parents, 12 teachers and 10 principals from 10 private English-speaking schools in Kolkata, India, participated in semi-structured interviews. The digitally-recorded conversations were transcribed verbatim and analysed thematically. The 52 interviews revealed a number of factors that may influence adolescents' eating habits including parent and peer influences, home and school food environments, and the mass media. Emerging evidence suggests that future health and nutrition promotion interventions need to target the different influences on Indian teenagers' food consumption. Copyright © 2016.

Modulation of Food Reward by Endocrine and Environmental Factors: Update and Perspective.

Science.gov (United States)

Figlewicz, Dianne P

2015-01-01

Palatable foods are frequently high in energy density. Chronic consumption of high-energy density foods can contribute to the development of cardiometabolic pathology including obesity, diabetes, and cardiovascular disease. This article reviews the contributions of extrinsic and intrinsic factors that influence the reward components of food intake. A narrative review was conducted to determine the behavioral and central nervous system (CNS) related processes involved in the reward components of high-energy density food intake. The rewarding aspects of food, particularly palatable and preferred foods, are regulated by CNS circuitry. Overlaying this regulation is modulation by intrinsic endocrine systems and metabolic hormones relating to energy homeostasis, developmental stage, or gender. It is now recognized that extrinsic or environmental factors, including ambient diet composition and the provocation of stress or anxiety, also contribute substantially to the expression of food reward behaviors such as motivation for, and seeking of, preferred foods. High-energy density food intake is influenced by both physiological and pathophysiological processes. Contextual, behavioral, and psychological factors and CNS-related processes represent potential targets for multiple types of therapeutic intervention.

This study examined the relationship between the neighborhood food environment and the food purchasing behaviors among adolescents. Grade 7 and 8 students (n = 810) at 21 elementary schools in London, Ontario, Canada completed a questionnaire assessing their food purchasing behaviors. Parents of participants also completed a brief questionnaire providing residential address and demographic information. A Geographic Information System (GIS) was used to assess students' home and school neighborhood food environment and land use characteristics. Logistic regression analysis was conducted to assess the influence of the home neighborhood food environment on students' food purchasing behaviors, while two-level Hierarchical Non-Linear Regression Models were used to examine the effects of school neighborhood food environment factors on students' food purchasing behaviors. The study showed that approximately 65% of participants reported self-purchasing foods from fast-food outlets or convenience stores. Close proximity (i.e., less than 1 km) to the nearest fast-food outlet or convenience store in the home neighborhood increased the likelihood of food purchasing from these food establishments at least once per week by adolescents (p purchasing by adolescents (i.e., at least once per week; p < 0.05). In conclusion, macro-level regulations and policies are required to amend the health-detracting neighborhood food environment surrounding children and youth's home and school.

Environmental, parental, and personal influences on food choice, access, and overweight status among homeless children.

Richards, Rickelle; Smith, Chery

2007-10-01

In-depth interviews were conducted with homeless children (n=56, aged 6-13 years) in an urban center in Minnesota, USA, to determine factors influencing food choice, food access, and weight status, with interview questions developed using the Social Cognitive Theory. Interview transcripts were coded and then evaluated both collectively and by weight status ( or = 85th percentile=overweight). Forty-five percent of children were overweight. Environmental, parental, and personal factors emerged as common themes influencing food access and choice. Despite children's personal food preferences, homelessness and the shelter environment created restrictive conditions that influenced food choice and access. Shelter rules, lack of adequate storage and cooking facilities, and limited food stores near the shelter, impacted the type and quality of food choices, ultimately affecting hunger, weight status, and perceived health.

A brief review of salient factors influencing adult eating behaviour.

Science.gov (United States)

Emilien, Christine; Hollis, James H

2017-12-01

A better understanding of the factors that influence eating behaviour is of importance as our food choices are associated with the risk of developing chronic diseases such as obesity, CVD, type 2 diabetes or some forms of cancer. In addition, accumulating evidence suggests that the industrial food production system is a major contributor to greenhouse gas emission and may be unsustainable. Therefore, our food choices may also contribute to climate change. By identifying the factors that influence eating behaviour new interventions may be developed, at the individual or population level, to modify eating behaviour and contribute to society's health and environmental goals. Research indicates that eating behaviour is dictated by a complex interaction between physiology, environment, psychology, culture, socio-economics and genetics that is not fully understood. While a growing body of research has identified how several single factors influence eating behaviour, a better understanding of how these factors interact is required to facilitate the developing new models of eating behaviour. Due to the diversity of influences on eating behaviour this would probably necessitate a greater focus on multi-disciplinary research. In the present review, the influence of several salient physiological and environmental factors (largely related to food characteristics) on meal initiation, satiation (meal size) and satiety (inter-meal interval) are briefly discussed. Due to the large literature this review is not exhaustive but illustrates the complexity of eating behaviour. The present review will also highlight several limitations that apply to eating behaviour research.

The art of grocery shopping on a food stamp budget: factors influencing the food choices of low-income women as they try to make ends meet.

2009-10-01

Amidst a hunger-obesity paradox, the purpose of the present study was to examine the grocery shopping behaviour and food stamp usage of low-income women with children to identify factors influencing their food choices on a limited budget. Focus groups, which included questions based on Social Cognitive Theory constructs, examined food choice in the context of personal, behavioural and environmental factors. A quantitative grocery shopping activity required participants to prioritize food purchases from a 177-item list on a budget of $US 50 for a one-week period, an amount chosen based on the average household food stamp allotment in 2005. Ninety-two low-income women, with at least one child aged 9-13 years in their household, residing in the Twin Cities, Minnesota, USA. Participants' mean age was 37 years, and 76% were overweight or obese (BMI> or =25.0 kg/m2). Key findings suggest that their food choices and grocery shopping behaviour were shaped by not only individual and family preferences, but also their economic and environmental situation. Transportation and store accessibility were major determinants of shopping frequency, and they used various strategies to make their food dollars stretch (e.g. shopping based on prices, in-store specials). Generally, meat was the most important food group for purchase and consumption, according to both the qualitative and quantitative data. Efforts to improve food budgeting skills, increase nutrition knowledge, and develop meal preparation strategies involving less meat and more fruits and vegetables, could be valuable in helping low-income families nutritionally make the best use of their food dollars.

Hernandez, Daphne C; Jacknowitz, Alison

2009-08-01

In this study, we examined characteristics associated with experiencing persistent and transitional adult food insecurity and how persistent and transitional adult food insecurity influences toddler cognitive and motor development, along with toddler's weight and health status. Using the first 2 waves of the Early Childhood Longitudinal Study-Birth Cohort, 4 mutually exclusive variables capturing persistent and transitional adult food insecurity were created to capture those adults that experience adult food insecurity in the following: both waves, in 1 wave (at 9 or 24 mo after birth), and never experience food insecurity. We used logistic regression models to estimate characteristics associated with the likelihood of experiencing persistent and transitional adult food insecurity. Ordinary least squares regression models were used to estimate how persistent and transitional adult food insecurity influences toddler development. Similar factors influenced one's likelihood of experiencing adult transitional and persistent food insecurity; individuals who experienced any food insecurity were more economically disadvantaged. Thus, outreach efforts do not need to vary by duration of food insecurity. Whereas negative effects of food insecurity on school-aged children are found in the literature, it appears toddlers are buffered from the effects of persistent adult food insecurity. Our findings suggest that toddlers residing with a temporarily food-insecure adult compared with a never food-insecure adult experienced immediate, but small, negative effects on their development. Hence, outreach and assistance may lessen immediate impacts of food insecurity on toddler development.

Food procurement can play an important role in sustainable food supply chain management by zoos, linking organizational operations to the biodiversity conservation and sustainability mission of zoological collections. This study therefore examines the critical factors that shape sustainable food procurement in zoo and aquariums. Using a web-based survey data was collected from 41 members of the British and Irish Association of Zoos and Aquariums (BIAZA). This included information on the sustainable food procurement practices of these institutions for both their human and animal food supply chains, as well as profile information and data on the factors contributing to and inhibiting sustainable procurement practices. Zoological collections operated by charities, and those with a certified sustainability standard, were found to have significantly higher levels of sustainable food procurement. Zoos and aquariums whose human food operations were not contracted to an external party were also found to have significantly higher levels of sustainable food procurement in their human food supply chain. The most important drivers of sustainable food procurement were cost savings, adequate financial support and improved product quality. The highest ranking barriers were higher costs, other issues taking priority and a lack of alternative suppliers. The results suggest that a number of critical factors shape sustainable food procurement in zoological collections in the British Isles. Financial factors, such as cost savings, were important considerations. The significance of mission-related factors, such as charity status, indicated that core values held by zoos and aquariums can also influence their food procurement practices. © 2015 Wiley Periodicals, Inc.

Food affordability and quality can influence food choice. This research explores the impact of geographic factors on food pricing and quality in Western Australia (WA). A Healthy Food Access Basket (HFAB) was cost and a visual and descriptive quality assessment of 13 commonly consumed fresh produce items was conducted in-store on a representative sample of 144 food grocery stores. The WA retail environment in 2010 had 447 grocery stores servicing 2.9 million people: 38% of stores the two major chains (Coles® Supermarkets Australia and Woolworths ® Limited) in population dense areas, 50% were smaller independently owned stores (Independent Grocers Association®) in regional areas as well, and 12% Indigenous community stores in very remote areas. The HFAB cost 24% (pfoods cost more and the quality of fresh produce was lower. Food affordability and quality may deter healthier food choice in geographically isolated communities. Improving affordability and quality of nutritious foods in remote communities may positively impact food choices, improve food security and prevent diet-sensitive chronic disease. Policy makers should consider influencing agriculture, trade, commerce, transport, freight, and modifying local food economies.

Wu, Yu-Mei; Wang, Zhi-Wei; Hu, Chang-Ying; Nerín, Cristina

2018-05-03

Antimicrobial packaging materials (films or coatings) (APMs) have aroused great interest among the scientists or the experts specialized in material science, food science, packaging engineering, biology and chemistry. APMs have been used to package the food, such as dairy products, poultry, meat (e.g., beef), salmon muscle, pastry dough, fresh pasta, bakery products, fruits, vegetables and beverages. Some materials have been already commercialized. The ability of APMs to extend the shelf-life of the food depends on the release rate of the antimicrobials (AMs) from the materials to the food. The optimum rate is defined as target release rate (TRR). To achieve TRR, the influencing factors of the release rate should be considered. Herein we reviewed for the first time these factors and their influence on the release. These factors mainly include the AMs, food (or food simulant), packaging materials, the interactions among them, the temperature and environmental relative humidity (RH).

Full Text Available The food sector in Europe can be characterized as a complex, global and dynamically changing network of trade streams, food supply network relations and related product flows which offers a big spectrum for economic output and employment. Innovation is important for the competitiveness of the food industry that is to a large extent comprised of small and medium sized enterprises (SMEs. For them, innovation has grown extremely subordinate to interaction in networks. Network initiatives that could provide appropriate support involve social interaction and knowledge exchange, learning and competence development, and coordination (organization and management ofimplementation. This paper is designed to assess the factors that affect the performance of German food SME formal networks. It also addresses the consequences at the network and macro level. The analysis was explored by using the laddering technique based on the means‐end chain theory. The findings will help to build up a “network learning toolbox” that is adapted to the particular requirements of the different target groups such as of SMEs, network managers and policy makers. The “network learning toolbox” should improve network learning, which is adriver for improvements in innovation, economic growth and sustainable competitive advantage for food SMEs.

Innovative food processing technologies have been widely investigated in food processing research in recent years. These technologies offer key advantages for advancing the preservation and quality of conventional foods, for combatting the growing challenges posed by globalization, increased competitive pressures and diverse consumer demands. However, there is a need to increase the level of adoption of novel technologies to ensure the potential benefits of these technologies are exploited more by the food industry. This review outlines emerging thermal and non-thermal food processing technologies with regard to their mechanisms, applications and commercial aspects. The level of adoption of novel food processing technologies by the food industry is outlined and the factors that impact their industrial adoption are discussed. At an industry level, the technological capabilities of individual companies, their size, market share as well as their absorptive capacity impact adoption of a novel technology. Characteristics of the technology itself such as costs involved in its development and commercialization, associated risks and relative advantage, its level of complexity and compatibility influence the technology's adoption. The review concludes that a deep understanding of the development and application of a technology along with the factors influencing its acceptance are critical for its commercial adoption.

In this paper, the environment is defined as the macro- and community-level factors, including physical, legal and policy factors, that influence household and individual decisions. Thus, environment is conceived as the external context in which household and individual decisions are made. This paper reviews the literature on the ways the environment affects diet, physical activity, and obesity. Other key environmental factors discussed include economic, legal, and policy factors. Behind the major changes in diet and physical activity in the US and globally lie large shifts in food production, processing, and distribution systems as well as food shopping and eating options, resulting in the increase in availability of energy-dense foods. Similarly, the ways we move at home, work, leisure, and travel have shifted markedly, resulting in substantial reductions in energy expenditure. Many small area studies have linked environmental shifts with diet and activity changes. This paper begins with a review of environmental influences on diet and physical activity, and includes the discussion of two case studies on environmental influences on physical activity in a nationally representative sample of US adolescents. The case studies illustrate the important role of physical activity resources and the inequitable distribution of such activity-related facilities and resources, with high minority, low educated populations at strong disadvantage. Further, the research shows a significant association of such facilities with individual-level health behavior. The inequity in environmental supports for physical activity may underlie health disparities in the US population.

There is consistent evidence that the amount of food we consume can be influenced by the eating behaviour of other people. Some previous experimental studies reported that consumers are unaware of this influence on their behaviour. The present research tested whether people may be more aware of social influence on their eating than previously assumed. In two studies, participants (total n = 160) were exposed to information about the amount of snack food other people had been eating shortly before being served the same snack food and eating as much as they liked. After this, participants responded to questions regarding whether they thought their food intake had been socially influenced, and reported the reasons why they believed they had or had not been influenced. Of the 160 participants, 34% reported that they had been influenced, 10% were unsure and 56% reported they had not been influenced. Crucially, participants' reports of social influence appeared to be accurate; the food intake of participants reporting social influence was significantly affected by the amount of food other people had been eating, whereas the food intake of participants denying social influence was unaffected. Individuals may be more aware of the effect that social influence has on their eating behaviour than previously assumed. Further work is needed to identify the factors which determine whether people are susceptible to social influence on eating behaviour. Copyright © 2014 Elsevier Ltd. All rights reserved.

Understanding factors that influence food choice may help improve diet quality. Factors that commonly affect adults' food choices have been described, but measures that identify and assess food choice factors specific to college students are lacking. This study developed and tested the Food Choice Priorities Survey (FCPS) among college students. Thirty-seven undergraduates participated in two focus groups ( n = 19; 11 in the male-only group, 8 in the female-only group) and interviews ( n = 18) regarding typical influences on food choice. Qualitative data informed the development of survey items with a 5-point Likert-type scale (1 = not important, 5 = extremely important). An expert panel rated FCPS items for clarity, relevance, representativeness, and coverage using a content validity form. To establish test-retest reliability, 109 first-year college students completed the 14-item FCPS at two time points, 0-48 days apart ( M = 13.99, SD = 7.44). Using Cohen's weighted κ for responses within 20 days, 11 items demonstrated moderate agreement and 3 items had substantial agreement. Factor analysis revealed a three-factor structure (9 items). The FCPS is designed for college students and provides a way to determine the factors of greatest importance regarding food choices among this population. From a public health perspective, practical applications include using the FCPS to tailor health communications and behavior change interventions to factors most salient for food choices of college students.

Factors that influence the reinforcing value of foods and beverages.

Temple, Jennifer L

2014-09-01

Behavioral economic principles state that as the cost of a product increases, purchasing or consumption of that product will decrease. To understand the impact of behavioral economics on ingestive behavior, our laboratory utilizes an operant behavior paradigm to measure how much work an individual will engage in to get access to foods and beverages. This task provides an objective measure of the reinforcing value. We have shown that consumption of the same high fat snack food every day for two weeks reduces its reinforcing value in lean individuals, but increases its reinforcing value in a subset of obese individuals. This increase in the reinforcing value of food predicts future weight gain. Similarly, we have shown that repeated intake of caffeinated soda increases its reinforcing value in boys, but not in girls. This increase in reinforcing value is not related to usual caffeine consumption, but may be associated with positive, subjective effects of caffeine that are more likely to be reported by boys than by girls. Because food and beverage reinforcement relates to real-world consumption, it is important to determine factors that increase or decrease the reinforcing value and determine the consequences of these responses. We are especially interested in determining ways to shift the behavioral economic curve in order to develop novel strategies to decrease the reinforcing value of less healthy snack foods and beverages, such as soda, potato chips and candy and to increase the reinforcing value of healthier foods and beverages, such as water, fruits, and vegetables.

Thai food industry employs a massive number of skilled and unskilled workers. This may result in an industry with high incidences and accident rates. To improve safety and reduce the accident figures, this paper investigates factors influencing safety implementation in small, medium, and large food companies in Thailand. Five factors, i.e., management commitment, stakeholders' role, safety information and communication, supportive environment, and risk, are found important in helping to improve safety implementation. The statistical analyses also reveal that small, medium, and large food companies hold similar opinions on the risk factor, but bear different perceptions on the other 4 factors. It is also found that to improve safety implementation, the perceptions of safety goals, communication, feedback, safety resources, and supervision should be aligned in small, medium, and large companies.

The factors influencing the priority of access to food and the effects of the priority of access to food on their carcass traits were analyzed for Japanese Black (Wagyu) cattle in a semi-intensive fattening production system. The records of 96 clinically healthy steers and heifers were analyzed. The calves at ∼3 to 4 months of age were allocated to pens with four animals per pen; all four animals in the same pen were of the same sex and of similar body size. The ranking of the animals' priority of access to food (1st, 2nd, 3rd and 4th), which was determined by the farm manager, was used as an indicator of social dominance in the present study. Four models including sire line, maternal grandsire line and the difference in the animals' birth dates as fixed effects were used to analyze factors influencing the priority of access to food. Ranking was represented by ordinal scores (highest=4, lowest=1) in Model 1, and the binary scores were assigned in Model 2 (highest=1; 2nd, 3rd and 4th=0), Model 3 (1st and 2nd=1; 3rd and 4th=0) and Model 4 (1st, 2nd and 3rd=1; lowest=0). The results showed that the difference in the animals' birth dates had a significant effect on the establishment of the priority of access to food in Model 3 (Panimals born earlier may become more dominant in the pen. The maternal grandsire line tended to affect the social rank score in Models 2 and 3 (Pcarcass weight (P=0.09). The highest BMS was observed for animals with the first rank of the priority of access to food (Panimals had the tendency to be heavier carcass than the lower-ranking animals. Our findings emphasized the importance of information about the priority of access to food determined by farmers' own observation on implementing best management practices in small-scaled semi-intensive beef cattle production systems.

Fast food is popular among children and adolescents; however, its consumption has often been associated with negative impacts on nutrition and health. This study examined current fast food consumption status among middle school students and explored factors influencing fast food consumption by applying Theory of Planned Behavior. A total of 354 (52.5% boys) students were recruited from a middle school. The subjects completed a pre-tested questionnaire. The average monthly frequency of fast food consumption was 4.05 (4.25 for boys, 3.83 for girls). As expected, fast food consumption was considered to be a special event rather than part of an everyday diet, closely associated with meeting friends or celebrating, most likely with friends, special days. The Theory of Planned Behavior effectively explained fast food consumption behaviors with relatively high R(2) around 0.6. Multiple regression analyses showed that fast food consumption behavior was significantly related to behavioral intention (b = 0.61, P intention was significantly related to subjective norm (b = 0.15, P fast food consumption was not significantly associated with behavioral intention. Therefore, effective nutrition education programs on fast food consumption should include components to change the subjective norms of fast food consumption, especially among peers, and perceived behavioral control. Further studies should examine effective ways of changing subjective norms and possible alternatives to fast food consumption for students to alter perceived behavioral control.

In the past few decades, many types of functional factors have been identified in dietary foods; for example, flavonoids are major groups widely distributed in the plant kingdom. However, the absorption rates of the functional food factors are usually low, and many of these are difficult to be absorbed in the intact forms because of metabolization by biological processes during absorption. To gain adequate beneficial effects, it is therefore mandatory to know whether functional food factors are absorbed in sufficient quantity, and then reach target organs while maintaining beneficial effects. These are the reasons why the bioavailability of functional food factors has been well investigated using rodent models. Recently, many of the biological processes have been reported to follow diurnal rhythms recurring every 24 h. Therefore, absorption and metabolism of functional food factors influenced by the biological processes may vary with time of day. Consequently, the evaluation of the bioavailability of functional food factors using rodent models should take into consideration the timing of consumption. In this review, we provide a perspective overview of the diurnal rhythm of biological processes involved in the bioavailability of functional food factors, particularly flavonoids.

Full Text Available Objectives: To investigate community support for government-led policy initiatives to positively influence the food environment, and to identify whether there is a relationship between support for food policy initiatives and awareness of the link between obesity-related lifestyle risk factors and cancer. Methods: An online survey of knowledge of cancer risk factors and attitudes to policy initiatives that influence the food environment was completed by 2474 adults from New South Wales, Australia. The proportion of participants in support of seven food policy initiatives was quantified in relation to awareness of the link between obesity, poor diet, insufficient fruit and vegetable consumption, and physical inactivity with cancer and other health conditions. Results: Overall, policies that involved taxing unhealthy foods received the least support (41.5%. Support was highest for introducing a colour-coded food labelling system (85.9%, restricting claims being made about the health benefits of foods which are, overall, unhealthy (82.6%, displaying health warning labels on unhealthy foods (78.7% and banning unhealthy food advertising that targets children (72.6%. Participants who were aware that obesity-related lifestyle factors are related to cancer were significantly more likely to support food policy initiatives than those who were unaware. Only 17.5% of participants were aware that obesity, poor diet, insufficient fruit and vegetable consumption, and physical inactivity are linked to cancer. Conclusions: There is strong support for all policies related to food labelling and a policy banning unhealthy food advertising to children. Support for food policy initiatives that positively influence the food environment was higher among those who were aware of the link between cancer and obesity-related lifestyle factors than among those who were unaware of this link. Increasing awareness of the link between obesity-related lifestyle factors and cancer

Nutrition labelling is an important strategic approach for encouraging consumers to make healthier food choices. The availability of highly palatable foods labelled as 'low fat or reduced calorie' may encourage the over-consumption of these products. This study aimed to determine whether the manipulation of nutrition labelling information can influence food portion size consumption. Normal and overweight men (n=24) and women (n=23) were served an identical lunch meal on three separate days, but the information they received prior to consuming the lunch meal was manipulated as follows: "baseline", "high fat/energy" and "low fat/energy". Food and energy intake was significantly increased in the low fat/energy condition compared with both baseline and the high fat/energy condition. An additional 3% (162 kJ) energy was consumed by subjects under the low fat/energy condition compared to baseline. No differences were observed between the baseline and high fat/energy condition. Subjects who consumed most in the low fat/energy condition were found to be mostly men, to have a higher BMI and to be overweight. Low fat/energy information can positively influence food and energy intake, suggesting that foods labelled as 'low fat' or 'low calorie' may be one factor promoting the consumption of large food portions.

Technological factors affecting biogenic amine content in foods: a review

Directory of Open Access Journals (Sweden)

Fausto Gardini

2016-08-01

Full Text Available Biogenic amines (BAs are molecules which can be present in foods and, due to their toxicity, can cause adverse effects on the consumers. BAs are generally produced by microbial decarboxylation of amino acids in food products. The most significant BAs occurring in foods are histamine, tyramine, putrescine, cadaverine, tryptamine, 2-phenylethylamine, spermine, spermidine and agmatine. The importance of preventing the excessive accumulation of BAs in food is related to their impact on human health and food quality. Quality criteria in connection with the presence of BAs in food and food products are necessary from a toxicological point of view. This is particularly important in fermented foods in which the massive microbial proliferation required for obtaining specific products is often relater with BA accumulation. In this review, up-to-date information and recent discoveries about technological factors affecting biogenic amine content in foods are reviewed. Specifically, BA forming-microorganism and decarboxylation activity, genetic and metabolic organization of decarboxylases, risk associated to BAs (histamine, tyramine toxicity and other BAs, environmental factors influencing BA formation (temperature, salt concentration, pH. In addition, the technological factors for controlling BA production (use of starter culture, technological additives, effects of packaging, other non-thermal treatments, metabolising BA by microorganisms, effects of pressure treatments on BA formation and antimicrobial substances are addressed.

Sex chromosome complement influences operant responding for a palatable food in mice.

Science.gov (United States)

Seu, Emanuele; Groman, Stephanie M; Arnold, Arthur P; Jentsch, J David

2014-07-01

The procurement and consumption of palatable, calorie-dense foods is influenced by the nutritional and hedonic value of foods. Although many factors can influence the control over behavior by foods rich in sugar and fat, emerging evidence indicates that biological sex may play a particularly crucial role in the types of foods individuals seek out, as well as the level of motivation individuals will exert to obtain those foods. However, a systematic investigation of food-seeking and consumption that disentangles the effects of the major sex-biasing factors, including sex chromosome complement and organizational and activational effects of sex hormones, has yet to be conducted. Using the four core genotypes mouse model system, we separated and quantified the effects of sex chromosome complement and gonadal sex on consumption of and motivation to obtain a highly palatable solution [sweetened condensed milk (SCM)]. Gonadectomized mice with an XY sex chromosome complement, compared with those with two X chromosomes, independent of gonadal sex, appeared to be more sensitive to the reward value of the SCM solution and were more motivated to expend effort to obtain it, as evidenced by their dramatically greater expended effort in an instrumental task with progressively larger response-to-reward ratios. Gonadal sex independently affected free consumption of the solution but not motivation to obtain it. These data indicate that gonadal and chromosomal sex effects independently influence reward-related behaviors, contributing to sexually dimorphic patterns of behavior related to the pursuit and consumption of rewards. © 2014 John Wiley & Sons Ltd and International Behavioural and Neural Genetics Society.

Socio-cultural and economic factors affecting food consumption patterns in the Arab countries.

Science.gov (United States)

Musaiger, A O

1993-04-01

Several factors have been found to determine the dietary habits of the people in the Arab world. Food consumption pattern has dramatically changed in some Arab countries as a result of sudden increase in income from oil revenue. It is believed that food subsidy policy has adversely affected the food habits in the Gulf states by encouraging the intake of fat, sugar, rice, wheat flour and meat. Socio-cultural factors such as religion, beliefs, food preferences, gender discrimination, education and women's employment all have a noticeable influence on food consumption patterns in this region. Mass media, especially televised food advertisements, play an important role in modifying the dietary habits. The migration movement, particularly that which was carried out during the 70s has a great impact on the food practices in many Arab countries. Comprehensive studies on social, cultural and economic factors associated with food consumption patterns in the Arab region are highly recommended.

AN EXPLORATORY STUDY OF MARKETING FACTORS INFLUENCING FAIRTRADE FOOD BUYING BEHAVIOUR IN THE UK

Directory of Open Access Journals (Sweden)

Fred Amofa Yamoah

2014-01-01

Full Text Available The phenomenal growth of the fairtrade industry has attracted increased research interest but little is known as to what marketing factors drive fairtrade retail sales. This gap has profound implications for fairtrade marketing research and the future of the fairtrade industry. To provide a more robust and objective insight this paper draws on the analysis of supermarket loyalty card dataset of 1.7 million fairtrade shoppers to establish the influence of price, promotion and distribution on fairtrade retail sales. Insights from the results show the lack of cross shopping pattern among fairtrade food product shoppers. The results also indicate that the increasing fairtrade retail sales growth is not shopper demand driven but predominately attributable to widened distribution and price increases. The findings of the study offer insights to fairtrade marketing researchers and strategic direction for managers working to ensure that fairtrade thrives as an ethical consumer driven industry.

2016-06-01

Full Text Available ABSTRACT Objective This study aimed to investigate aspects associated with food involvement and to ascertain whether individuals with higher food involvement consume larger amounts of fruits and vegetables. Methods This cross-sectional, analytical study was conducted with 301 adults (19-59 years old from the Federal District, Brazil. Sample size calculation was based on numbers from the Brazilian Demographic Census and on consumption data for fruits and vegetables obtained from the Surveillance of Risk and Protective Factors for Chronic Diseases by Telephone Interviews survey. Data were collected in October of 2012. The questionnaire comprised 28 questions and included socio-demographic variables, reported fruit and vegetable consumption, and an adapted food involvement scale. Data were analyzed using Statistical Package for the Social Sciences software. Descriptive and comparative analyses were performed to determine population characteristics . Results Women and older individuals displayed a higher degree of food involvement than did men and younger individuals ( p <0.001. Among the factors included in food involvement, the highest influence was attributed to satisfaction in preparing food (cooking, pre-preparation of food, and pleasure in cooking for other people ( p <0.001. Conclusion The results presented here suggest that food involvement can be stimulated through innovative strategies of communication that go beyond the biological arguments and focus on the cultural expression of the elements of socialization, whose relationship with eating is well established.

Tremendous increases in biodegradable (food waste) generation significantly impact the local authorities, who are responsible to manage, treat and dispose of this waste. The process of separation of food waste at its generation source is identified as effective means in reducing the amount food waste sent to landfill and can be reused as feedstock to downstream treatment processes namely composting or anaerobic digestion. However, these efforts will only succeed with positive attitudes and highly participations rate by the public towards the scheme. Thus, the social survey (using questionnaires) to analyse public's view and influencing factors towards participation in source separation of food waste in households based on the theory of planned behaviour technique (TPB) was performed in June and July 2011 among selected staff in Universiti Putra Malaysia, Serdang, Selangor. The survey demonstrates that the public has positive intention in participating provided the opportunities, facilities and knowledge on waste separation at source are adequately prepared by the respective local authorities. Furthermore, good moral values and situational factors such as storage convenience and collection times are also encouraged public's involvement and consequently, the participations rate. The findings from this study may provide useful indicator to the waste management authorities in Malaysia in identifying mechanisms for future development and implementation of food waste source separation activities in household programmes and communication campaign which advocate the use of these programmes.

Ma, R; Castellanos, D C; Bachman, J

2016-07-01

China is in the midst of the nutrition transition with increasing rates of obesity and dietary changes. One contributor is the increase in fast food chains within the country. The purpose of this study was to develop a theory-based instrument that explores influencing factors of fast food consumption in adolescents residing in Beijing, China. Cross-sectional study. Value expectancy and theory of planned behaviour were utilised to explore influencing factors of fast food consumption in the target population. There were 201 Chinese adolescents between the ages of 12 and 18. Cronbach's alpha correlation coefficients were used to examine internal reliability of the theory-based questionnaire. Bivariate correlations and a MANOVA were utilised to determine the relationship between theory-based constructs, body mass index (BMI)-for-age and fast food intake frequency as well as to determine differences in theory-based scores among fast food consumption frequency groupings. The theory-based questionnaire showed good reliability. Furthermore, there was a significant difference in the theory-based subcategory scores between fast food frequency groups. A significant positive correlation was observed between times per week fast food was consumed and each theory-based subscale score. Using BMI-for-age of 176 participants, 81% were normal weight and 19% were considered overweight or obese. Results showed consumption of fast food to be on average 1.50 ± 1.33 per week. The relationship between BMI-for-age and times per week fast food was consumed was not significant. As the nutrition transition continues and fast food chains expand, it is important to explore factors effecting fast food consumption in China. Interventions targeting influencing factors can be developed to encourage healthy dietary choice in the midst of this transition. Copyright © 2016. Published by Elsevier Ltd.

Postprandial lipemia: factoring in lipemic response for ranking foods for their healthiness.

2017-09-18

One of the limitations for ranking foods and meals for healthiness on the basis of the glycaemic index (GI) is that the GI is subject to manipulation by addition of fat. Postprandial lipemia, defined as a rise in circulating triglyceride containing lipoproteins following consumption of a meal, has been recognised as a risk factor for the development of cardiovascular disease and other chronic diseases. Many non-modifiable factors (pathological conditions, genetic background, age, sex and menopausal status) and life-style factors (physical activity, smoking, alcohol and medication use, dietary choices) may modulate postprandial lipemia. The structure and the composition of a food or a meal consumed also plays an important role in the rate of postprandial appearance and clearance of triglycerides in the blood. However, a major difficulty in grading foods, meals and diets according to their potential to elevate postprandial triglyceride levels has been the lack of a standardised marker that takes into consideration both the general characteristics of the food and the food's fat composition and quantity. The release rate of lipids from the food matrix during digestion also has an important role in determining the postprandial lipemic effects of a food product. This article reviews the factors that have been shown to influence postprandial lipemia with a view to develop a novel index for ranking foods according to their healthiness. This index should take into consideration not only the glycaemic but also lipemic responses.

A Comprehensive Examination of the Determinants for Food Risk Perception: Focusing on Psychometric Factors, Perceivers' Characteristics, and Media Use.

Risk characteristics within a psychometric paradigm have been of major concern in studies of food risk perception. This study compared the influence of psychometric factors, perceivers' characteristics (i.e., risk attitude, trust, and favorability of the country of origin), and that of the news media on the levels of food risk perception. The interaction of news media with the other two factors was also examined. A nationwide survey (n = 1,500) was conducted. The foods under investigation were Chinese processed foods and Japanese seafood imported to South Korea. In both cases, hierarchical multiple regression analyses revealed that psychometric factors had the greatest influence on food risk perception, followed by perceivers' characteristics and media use. In addition, our results showed that the effect of perceived benefit and dread in Chinese food were salient only for those with little media use. The implication of the interaction effect on food risk perception is discussed in terms of accessibility and limited capacity of information processing.

Interviews were transcribed verbatim and analysed using inductive thematic analysis. overweight/obese women perceived the following factors to influence their food choices and PA behaviours: personal (e.g. age, enjoyment, health, aesthetic appearance, and response to fatigue); social (e.g. social support, food modelling, social facilitation and weight bias) and environmental (e.g. food salience and the obesogenic environment). These factors affected PA and food choice trajectories differently according to socio-economic and socio-cultural context. personal, social and environmental factors affect food choices and PA behaviours. Pregnancy is a powerful stimulus for positive changes in food choices particularly. This change is driven by desire for healthy pregnancy outcome, and is not intrinsically motivated. Healthy lifestyle interventions should aim to sustain positive changes beyond pregnancy through: empowerment, intrinsic motivation, family-centred approach, and behavioural goals. Copyright © 2017.

Vitamin A deficiency is one of the most prevalent deficiency disorders in the world. As shown by many studies plant food based approaches have a real potential on prevention of vitamin A deficiency in a sustainable way. Carotenoids are important as precursors of vitamin A as well as for prevention of cancers, coronary heart diseases, age-related macular degeneration, cataract etc. Bioaccessibility and bioefficacy of carotenoids are known to be influenced by numerous factors including dietary factors such as fat, fiber, dosage of carotenoid, location of carotenoid in the plant tissue, heat treatment, particle size of food, carotenoid species, interactions among carotenoids, isomeric form and molecular linkage and subject characteristics. Therefore even when carotenoids are found in high quantities in plant foods their utilization may be unsatisfactory because some factors are known to interfere as negative effectors.

Full Text Available The purpose of this study was to establish food ingestion factors needed to assess exposure to contaminants through food ingestion. The study reclassified the raw data of the Korean National Health and Nutrition Examination Survey in 2001 into 12 subcategories including grain products, meat products, fish and shellfish, and vegetables for international comparability of exposure evaluation. The criteria for food intake calculation were unified according to the characteristics of food groups, and recommended values for food ingestion factors were calculated through moisture correction and recategorization of cooked, processed, and mixed foods for each group. The average intake rate for grain and grain products was 6.25 g/kg-d per capita and the men's intake rate was approximately 8% higher than that of the women. The average intake rate of meat and meat products was 1.62 g/kg-d per capita and the men's intake rate was 30% higher than that of the women, on average. The average intake rate of fish and shellfish was 1.53 g/kg-d per capita, and the age groups of 1 to 2 and 3 to 6 recorded higher capita intake rates than other age groups, 2.62 g/kg-d and 2.25 g/kg-d, respectively. The average intake rate of vegetables was 6.47 g/kg-d per capita, with the age group of 1 to 2 recording the highest per capita intake rate of 9.79 g/kg-d and that of 13 to 19 recording the lowest mean. The study also offers recommended values for food ingestion factors of other food groups by gender, age, and region. The food ingestion exposure factors will need future updates in consideration of ongoing changes in food consumption behavior.

Food preferences are important determinants of children's food intakes. Parental feeding behaviours have a significant influence on the development of children's food preferences. The aim of the present study was to describe the ways in which parents attempt to influence their children's food preferences. Parents of 2-5 year old children participated in semi-structured qualitative interviews, which were transcribed and content analysed using a thematic coding manual. The parents described the ways in which they tried to influence the foods their child liked and disliked. Participants (N = 57) were separated into three separate groups based on an a priori study measuring food preferences and food neophobia: those who either had children with healthy food preferences (i.e. closely aligned with dietary guidelines) (N = 20), or unhealthy food preferences (i.e. not closely aligned with dietary guidelines) (N = 18), or high levels of food neophobia (N = 19). The parents used many, diverse behaviours to influence their child's food preferences. Some of these behaviours were likely to be effective in promoting healthy food preferences in children (e.g. parental modelling, food exposure), whilst others were likely to be ineffective (e.g. forcing consumption, restricting food access). Parents of children with healthy food preferences appeared to use more of the feeding behaviours predicted to promote healthy preferences than parents in the other two groups. Parents of children with unhealthy food preferences and those of food neophobic children appeared to rely more on ineffective behaviours. Parents used a mixture of effective and ineffective behaviours, with parents of children with unhealthy food preferences or high food neophobia using fewer behaviours known to be effective. Interventions aimed at influencing parental feeding behaviours should include those behaviours targeted at children's food preferences. Copyright © 2015 Elsevier Ltd. All rights

This study explored how mothers grouped into clusters according to multiple psychographic food decision influencers and how the clusters differed in nutrient intake and nutrient content of their household food supply. Mothers (n = 201) completed a survey assessing basic demographic characteristics, food shopping and meal preparation activities, self and spouse employment, exposure to formal food or nutrition education, education level and occupation, weight status, nutrition and food preparation knowledge and skill, family member health and nutrition status, food decision influencer constructs, and dietary intake. In addition, an in-home inventory of 100 participants' household food supplies was conducted. Four distinct clusters presented when 26 psychographic food choice influencers were evaluated. These clusters appear to be valid and robust classifications of mothers in that they discriminated well on the psychographic variables used to construct the clusters as well as numerous other variables not used in the cluster analysis. In addition, the clusters appear to transcend demographic variables that often segment audiences (eg, race, mother's age, socioeconomic status), thereby adding a new dimension to the way in which this audience can be characterized. Furthermore, psychographically defined clusters predicted dietary quality. This study demonstrates that mothers are not a homogenous group and need to have their unique characteristics taken into consideration when designing strategies to promote health. These results can help health practitioners better understand factors affecting food decisions and tailor interventions to better meet the needs of mothers.

The gamma contamination food factor

We suggest that radioactive food contamination, as determined solely by a quantitative gamma-ray spectroscopic measurement, may, apart from the total activity per unit mass, be for quick reference conveniently characterized by another single figure which we call the ''Gamma Contamination Food Factor'' (GCFF). This factor may be defined as the ratio of the total specific activity of gamma-ray-emitting radionuclides in the food sample (except that of 40 K) to the specific activity of 40 K either in the sample itself or in an ''average man''. We discuss briefly the meaning and advantages of these definitions. (author)

The effects of audiovisual presentation on consumers' knowledge and attitudes toward food irradiation were demonstrated. Food irradiation is a method of food preservation that can destroy the microorganisms responsible for many foodborne illnesses and food spoilage. However, the food industry has been slow to adopt this method because it is unsure of consumer acceptance. One hundred and seventy-nine consumers were given a slide-tape presentation on food irradiation. Test subjects were also presented with a sample of irradiated strawberries. It was found that participants knew more about and were more positive toward food irradiation following the educational program. These findings demonstrate the value of educational materials in influencing the food preferences of consumers

University students generally make independent decisions regarding food choices. Current research about knowledge of Australian Dietary Guidelines (ADG), sources of nutrition information and influences on food choices for this group is scarce. Qualitative data was collected from gender separated focus groups comprising four female (n=31) and four male (n=18) to identify: knowledge of ADG, sources of nutrition information; factors that influence food choices; perceived relevant nutrition messages and how best to deliver them. Gaps in knowledge were identified particularly regarding number of serves and serving size for food groups. Social media was the most commonly reported source of knowledge. Social media was also a major influence on food choice due to its impact on body ideals. Current health promotion nutrition messages were perceived irrelevant given the focus on long-term health risks. Health and adhering to the ADG were not identified as important. The desire to look a particular way was the major influence on food choices. SO WHAT?: While there is an awareness of ADG, our participants made a deliberate decision not to follow them. This provides a challenge for developing relevant preventive health messages for this target audience. This article is protected by copyright. All rights reserved.

Full Text Available The increase in the incidence of nephropathy arouses concern and necessitates the further study of kidney disease factors in the children. Objective: to determine the effect of food colors on the development of kidney pathology in the children. Materials and methods. We observed 199 children aged from 1 year to 17 years, who were divided into two groups: group 1 — 103 children with various renal diseases, group 2 — 96 somatically healthy children. Effect of food colors on children’s kidneys was studied using a questionnaire survey of parents and the child. Results. Mothers of children with kidney disease significantly more frequently had used foods containing food colors (ice cream, confectionery, candies, soft drinks, such as fanta, lemonade, etc. before, during and after pregnancy. The same situation is observed when determining the frequency of using food colors by children: children from group 1 in 14.5 % of cases eat such products continuously, in 36.9 % of cases — often, but not every day, and in 29.1 % of cases — several times a month. While children from group 2 constantly consume foods with food colors only in 4.2 % of cases, often, but not every day — in 20.8 % of cases, several times a month — in 29.1 %. Conclusion. Various environmental factors, such as food colors, influence the development of the child’s body, reducing the adaptive capacity of the kidneys, or directly affecting them.

The aim of the study is to investigate the influence of the school food environment on the dietary behaviours of 11-year-old Norwegian children in elementary schools. Baseline data from a school-based intervention study: the Health In Adolescents study was used. A total of 1425 11-year-old children from 35 schools from the eastern part of Norway were included. School administrators provided information on the physical, political, and sociocultural school food environment and students reported their intake of fruits, vegetables, sugar-sweetened beverages (SSB), and snacks. Multilevel modelling was used to assess the school-level variance in dietary behaviours and to investigate the association of school food environmental factors with these dietary behaviours. After adjustment for student characteristics, the school level accounted for a small proportion (1.1%-3.0%) of the variance in the dietary behaviours investigated. None of the investigated school food environmental factors were found to be related to the children's reported intake of fruits, vegetables, snacks or SSB. Most of the variance in the dietary behaviours investigated was at the personal level. Thus in this sample, the investigated school-level factors do not appear to exert a strong influence on the dietary behaviours of children. Longitudinal studies using validated measures of the school food environment are needed.

The influence of food consistency on chewing rate and muscular work.

Science.gov (United States)

van der Bilt, A; Abbink, J H

2017-11-01

Food properties influence the parameters of the masticatory process, such as jaw movement, muscle activity and chewing rate. Firm foods will require more muscle activity than softer foods. However, the influence of food hardness on chewing rate is ambiguous as both slower and higher chewing rates have been reported for harder foods. Rheological characteristics of the food, such as plasticity and elasticity, may help to explain differences in chewing rate. The aim of our study was to determine the influence of food properties on chewing rate and muscular work in five phases of a chewing sequence. Eighty-four participants chewed on five foods, which strongly differed in consistency. Chewing gum was used as a reference food. The phase in the chewing sequence had a large significant effect on cycle duration for the five foods. A significant decrease in cycle duration at the beginning of chewing was followed by an increase in later phases, leading to U-shaped curves. Food type had a small effect on the average cycle duration. However, large significant differences in cycle duration were observed between the foods at the beginning of a chewing sequence. In that phase, the firm foods were chewed much slower than the soft foods. Muscular work was significantly influenced by both chewing phase and food type. Copyright © 2017 Elsevier Ltd.

Carrillo, E; Varela, P; Fiszman, S

2012-01-01

The present study analyzed the nutritional knowledge of Spanish consumers and its relationship with the correct use of food labels. Consumers were asked about their nutritional knowledge and some functional foods and about their understanding of food labeling and their use of it to select healthy food. A 2-part questionnaire was employed. The 1st part concerned their knowledge of nutritional facts, including their knowledge about macronutrients and perception of certain functional foods, while the 2nd part addressed some questions regarding food labels. The results revealed no statistically significant differences in nutritional knowledge by either age or gender, but a direct relationship with educational level. The association between nutritional knowledge and the perception and understanding of food labeling showed that the nutritional label rarely influenced the food purchases of the group with low nutritional knowledge, who considered that this information was too technical. More than half of the consumers did not consider the calorie or sugar content important for selecting food. In addition, the group with low nutritional knowledge stated that they never or rarely looked at the food labels to check whether it was low-fat food that they were buying. Knowing the status of the consumer's nutritional knowledge allows health campaigns to be designed; considering the influence of cultural factors and the perception of food labeling is very useful for promoting better nutritional information. © 2011 Institute of Food Technologists®

Nanotechnology can be described as an emerging technology and, as has been the case with other emerging technologies such as genetic modification, different socio-psychological factors will potentially influence societal responses to its development and application. These factors will play an important role in how nanotechnology is developed and commercialised. This article aims to identify expert opinion on factors influencing societal response to applications of nanotechnology. Structured interviews with experts on nanotechnology from North West Europe were conducted using repertory grid methodology in conjunction with generalized Procrustes analysis to examine the psychological constructs underlying societal uptake of 15 key applications of nanotechnology drawn from different areas (e.g. medicine, agriculture and environment, chemical, food, military, sports, and cosmetics). Based on expert judgement, the main factors influencing societal response to different applications of nanotechnology will be the extent to which applications are perceived to be beneficial, useful, and necessary, and how 'real' and physically close to the end-user these applications are perceived to be by the public.

To investigate the dietary pattern in college freshmen students and to analyze the influencing factors on their dietary patterns. A questionnaire survey on situation of dietary pattern and influencing factors was conducted among 1319 freshmen students. Four major dietary patterns were noticed and they were: I, high consumption in hamburger, fried food, nuts, biscuit, chocolate, cola, coffee, sugars, II, high consumption in pork, mutton, beef, poultry meat, animal liver, III, high consumption in fresh fruits, eggs, fish and shrimps, kelp laver and sea fish, milk and dairy products, beans and bean products, IV, high consumption in rice and grain, fresh fruits, fresh vegetables, pork. Risk factors on dietary pattern were presented as follows: (1) boys:having the food pattern I and II showed a strong positive association with the place where they live (OR = 1.67, 95%CI: 0.87 - 3.19; OR = 1.51, 95%CI: 0.79 - 2.88), eating place (OR = 1.63, 95%CI: 1.03 - 2.59;OR = 1.83, 95%CI: 1.04 - 3.23), level of mother's education (OR = 2.52, 95%CI: 1.07 - 5.95; OR = 3.38, 95%CI: 1.50 - 7.63), family income (OR = 2.24, 95%CI: 1.30 - 3.88; OR = 3.06, 95%CI: 1.77 - 5.29) and the status of passive smoking (OR = 1.80, 95%CI: 0.70 - 4.59; OR = 1.83, 95%CI: 0.75 - 4.45). Inverse correlations was found on the level of mother's education (OR = 0.56, 95%CI: 0.17 - 1.79). The food pattern IV showed a strong positive association with place of eating (OR = 1.83, 95%CI: 1.04 - 3.23) but having an inverse correlation with the level of mother's education (OR = 0.56, 95%CI: 0.17 - 1.79). (2) girls when compared with boys, the food pattern I showed minor association with the places of living and eating; while the food pattern II and III had minor association with the status of passive smoking. Socio-demographic factors and lifestyle had influenced on the dietary patterns among college freshmen students who should be guided to have a reasonable, balanced diet in the college.

Provencher, Véronique; Jacob, Raphaëlle

2016-03-01

Healthy eating is an important determinant of health, but adherence to dietary guidelines remains a public health concern. Identifying factors that impact dietary habits is therefore important to facilitate healthy eating. One widely used strategy to help consumers make healthier food choices is nutrition information, such as labeling and claims. Despite the intention of these strategies to improve decision making, they can also be misunderstood or misinterpreted by consumers. The aim of this review is to explore food perceptions by examining how cognitive factors influence perceived healthiness of food, and the impact of perceived healthiness of food on food choices and intake. Overall findings of this review suggest that cognitive factors, such as type of food and branding, significantly contribute to judgmental bias and have an impact on perceived healthiness while not consistently or systematically influencing choice and intake.

Falls are responsible for a substantial injury burden in the global workplace. Restaurant environments are particularly challenged by slips, trips, and falls. This study explored those factors that could influence workers' self-reports of slipperiness in U.S. fast-food restaurants. One hundred and twenty-six workers employed in 10 fast-food restaurants in the northeastern United States participated in the study representing a study-wide response rate of 87.5%. Participants' ratings of floor slipperiness and occupational slip history within the past 4 weeks were collected through written questionnaire. Additional factors collected by questionnaire included age, gender, shift length, and shoe type. Shoe condition (wear) and shoe contamination were visually assessed by the investigators. Floor friction was also measured. Lower restaurant mean coefficient of friction and the presence of contamination on workers' shoe soles were environmental factors significantly associated with workers reporting more slippery conditions. A recent workplace history of slipping with or without a subsequent fall was also significantly associated with workers reporting more slippery conditions. Workers over the age of 45 reported conditions to be significantly less slippery than younger workers. The results suggest that worker ratings of slipperiness are influenced not only by the actual level of friction but also by the other individual and environmental factors noted above. Recommendations for future studies would include a longitudinal design to better capture the temporal sequence between these variables. More field research is needed to better understand the association between workplace conditions, worker perception of slipperiness, and slipping at work.

This study investigated multiple social influences to determine whether they affect amount eaten at a fast-food environment. Using observational methods, data on meal duration, foods eaten and personal characteristics were collected for 157 McDonald's patrons. Analysis of covariance revealed that female diners ate less kilojoules when eating in mixed- versus same-sex groups (adjusted difference = 967 kJ, p < .05), while male diners eating in mixed-sex company ate more in groups compared to pairs (adjusted difference = 1067 kJ, p = .019). Influences to increase and restrict the amount eaten can operate simultaneously in an eating environment with gender a critical factor for consideration. © The Author(s) 2015.

The influence of oral health on patients' food perception: a systematic review.

Batisse, C; Bonnet, G; Eschevins, C; Hennequin, M; Nicolas, E

Oral food perception depends on somatosensory information that includes taste and can be modified by oral components and/or functions such as mastication. The purpose of this study was to describe the interplay between oral health, mastication and taste. A review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist was conducted on 615 publications found by both PubMed and backward research. Thirty-one studies have been included. The results showed that the decline in taste ability observed during the healthy ageing process could be potentiated by the deterioration of oral health and poor oral hygiene. Prosthetic treatment could modify taste ability and oral food perception. A palatal covering with removable dentures can have an impact on taste perception which may depend on taste modality. During the mastication sequence, taste is apparently scattered throughout the oral cavity, probably through saliva. The deterioration of masticatory function modifies taste perception. Oral health and oral care should consider factors influencing patients' food perception and relations between taste and mastication. Therefore, dentists may modulate these factors to improve food perception and patients' eating pleasure and quality of life. © 2017 John Wiley & Sons Ltd.

Food allergies affect up to 8% of children in the United States and may occasionally lead to severe life-threatening reactions. Because there is currently no cure for food allergies, strict avoidance of the allergen-containing foods is the only means of preventing an allergic reaction. Consumers rely on food manufacturers to reliably track and declare the presence of food allergens in products. Over the past 10 to 20 years, the food industry has increasingly adopted allergen control approaches in its processing facilities. However, the major industry costs related to food allergen management have not been fully described. The objective of this study was to characterize the factors that contribute to the economic impact of food allergen control practices on the food industry. A focus group (n = 100) was conducted with food industry professionals to identify key areas of cost for food allergen management. A survey based on the domains identified was then developed and disseminated to a convenience sample (n = 50) of quality control food industry specialists with knowledge of their company's food allergen management practices. Nearly all companies (92%) produced food products containing one or more of the top eight allergenic foods recognized by the U.S. Food and Drug Administration or sesame seeds. Cleaning procedures, employee training, and the potential for a recall due to allergen cross-contact were most frequently rated as the important factors in food allergen management. Recalls due to food allergen cross-contact, cleaning procedures, equipment and premises design, and employee training were ranked as the greatest allergen management expenses. Although 96% of companies had a food allergen control plan in place, nearly half (42%) had at least one food allergen-related recall within the past 5 years. The industry appears to endorse a willingness to unify precautionary allergen labeling to communicate a clear message more effectively to consumers.

The survey studies the effects of six factors including customer's perception, persuasive factors, brand, customers' expectations, product's characteristics and special features of store on attracting more customers. We have distributed questionnaire among 196 customers who regularly visit stores and analyzed details of the data. The results indicate that customers' perception is the most important item, which includes eight components. Years of experience is the most important item in our survey followed by impact of color and working hours. Diversity of services is another factor, which plays the most important role followed by quality of services. Next, fidelity and brand are other most important factors and the name of store and risk are in lower degree of importance.

Animal welfare versus food quality: factors influencing organic consumers' preferences for alternatives to piglet castration without anaesthesia.

Heid, Astrid; Hamm, Ulrich

2013-10-01

Surgical piglet castration without pain relief has been banned in organic farming in the EU since the beginning of 2012. Alternative methods therefore need to be implemented that improve animal welfare and solve the underlying problem of boar taint. This paper explores German organic consumers' preferences for piglet castration without pain relief and three alternative methods. In an innovative approach using a multi-criteria decision making procedure, qualitative data from focus group discussions were compared with quantitative results from Vickrey auctions. Overall, participants preferred all alternatives to castration without pain relief. Different aspects influenced willingness-to-pay for the methods. Animal welfare was important for the evaluation of castration without pain relief and castration with anaesthesia. Food safety played a major role for willingness-to-pay for immunocastration, while taste and, to some extent, animal welfare were dominant factors for fattening of boars. These differences should be considered when communicating the alternatives. Copyright © 2013 Elsevier Ltd. All rights reserved.

Gender inequities place women at an increased risk for HIV acquisition, and this association may particularly disenfranchize young pregnant women. Intimate partner violence (IPV) and food insecurity may contribute to gender differences in power, thereby influencing HIV disparities between women and men. Factors influencing gender disparities in HIV are unique and country-specific within sub-Saharan Africa, yet these factors are understudied among women in Liberia. This paper sought to examine the unique contributions and intersections of intimate partner violence (IPV) and food insecurity with HIV-related risk factors among young pregnant women in Liberia. Between March 2016 and August 2016, cross-sectional data collected from 195 women aged 18-30, residing in Monrovia, Liberia who were receiving prenatal services were used to examine the independent and interaction effects of IPV and food insecurity on HIV-related risk factors (i.e., sexual partner concurrency, economically-motivated relationships). IPV (31.3%) and food insecurity (47.7%) were prevalent. Young women who experience IPV are more likely to report food insecurity (p insecurity were more likely to start a new relationship for economic support (ps insecurity were more likely to report engaging in transactional sex (ps insecurity (ps > 0.05). IPV and food insecurity each uniquely heighten young Liberian women's vulnerability to HIV. Intervention and policy efforts are need to promote and empower women's sexual health through integrated sexual and reproductive health services, and reduce IPV and food insecurity among pregnant Liberian women.

Rodríguez-Entrena, Macario; Salazar-Ordóñez, Melania

2013-01-01

The application of genetic engineering to agriculture has led to an important and controversial innovation in the food sector, so-called Genetically Modified (GM) food. A great deal of literature has studied cognitive and attitudinal factors conditioning consumers' acceptance of GM food, knowledge being one of the most inconsistent variables. Notwithstanding, some authors suggest closer attention should be paid to "science literacy", even more so than knowledge. This paper studies the potential role of consumer literacy fields - i.e. consumer scientific-technical or social-humanistic literacy - in determining consumer choice behaviour towards GM foods. We analyse the strength of the moderating effects produced by consumer university training in some of the most important factors which influence consumers' innovative product acceptance, such as perceived benefits and risks, attitudes to GM technology, trust in institutions or knowledge. The research is performed in southern Spain, using a variance-based technique called Structural Equation Modelling by Partial Least Squares (PLSs). The results show that perceived benefits and risks play a significant role in shaping behavioural intentions towards GM food, the attitude to GM technology being the main driver of consumers' beliefs about risks and benefits. Additionally, behavioural intentions display some differences between the scientific-technical and social-humanistic literacy fields, the variables of trust in institutions and knowledge registering the most striking differences.

Nanotechnology has the potential to generate new food products and new food packaging. In a mail survey in the German speaking part of Switzerland, lay people's (N=337) perceptions of 19 nanotechnology applications were examined. The goal was to identify food applications that are more likely and food applications that are less likely to be accepted by the public. The psychometric paradigm was employed, and applications were described in short scenarios. Results suggest that affect and perceived control are important factors influencing risk and benefit perception. Nanotechnology food packaging was assessed as less problematic than nanotechnology foods. Analyses of individual data showed that the importance of naturalness in food products and trust were significant factors influencing the perceived risk and the perceived benefit of nanotechnology foods and nanotechnology food packaging.

Neighborhood fast food availability and fast food consumption.

Science.gov (United States)

Oexle, Nathalie; Barnes, Timothy L; Blake, Christine E; Bell, Bethany A; Liese, Angela D

2015-09-01

Recent nutritional and public health research has focused on how the availability of various types of food in a person's immediate area or neighborhood influences his or her food choices and eating habits. It has been theorized that people living in areas with a wealth of unhealthy fast-food options may show higher levels of fast-food consumption, a factor that often coincides with being overweight or obese. However, measuring food availability in a particular area is difficult to achieve consistently: there may be differences in the strict physical locations of food options as compared to how individuals perceive their personal food availability, and various studies may use either one or both of these measures. The aim of this study was to evaluate the association between weekly fast-food consumption and both a person's perceived availability of fast-food and an objective measure of fast-food presence - Geographic Information Systems (GIS) - within that person's neighborhood. A randomly selected population-based sample of eight counties in South Carolina was used to conduct a cross-sectional telephone survey assessing self-report fast-food consumption and perceived availability of fast food. GIS was used to determine the actual number of fast-food outlets within each participant's neighborhood. Using multinomial logistic regression analyses, we found that neither perceived availability nor GIS-based presence of fast-food was significantly associated with weekly fast-food consumption. Our findings indicate that availability might not be the dominant factor influencing fast-food consumption. We recommend using subjective availability measures and considering individual characteristics that could influence both perceived availability of fast food and its impact on fast-food consumption. If replicated, our findings suggest that interventions aimed at reducing fast-food consumption by limiting neighborhood fast-food availability might not be completely effective

The influence of media characters on children's food choices.

Science.gov (United States)

Kotler, Jennifer A; Schiffman, Jennifer M; Hanson, Katherine G

2012-01-01

Two experiments were conducted to assess the role of media characters in influencing children's food choices; the first focused on children's self-reported preference, whereas the second focused on actual choice. The results of the experiments suggest that popular characters can make a difference in encouraging children to select one food over another. In the first experiment, children were more likely to indicate a preference for one food over another when one was associated with characters that they liked and with whom they were familiar. This effect was particularly strong when a sugary or salty snack branded by a favored character was competing with a healthier option branded by an unknown character or no character. Alternatively, when children were asked to choose between a healthy food and a sugary or salty snack, branding of the healthy food with a favored character did not significantly change appeal of that healthy snack. However, when foods within the same category (i.e., 2 vegetables, 2 fruits, or 2 grains) were asked to compete against each other, character branding strongly influenced children's food choice. Findings from the second experiment suggest that children are more willing to try more pieces of a healthy food if a favored character, in comparison with an unknown character, is promoting that food.

The influence of oral processing, food perception and social aspects on food consumption: a review.

Science.gov (United States)

Pereira, L J; van der Bilt, A

2016-08-01

Eating is an essential activity to get energy and necessary nutrients for living. While chewing, the food is broken down by the teeth and dissolved by saliva. Taste, flavour and texture are perceived during chewing and will contribute to the appreciation of the food. The senses of taste and smell play an important role in selecting nutritive food instead of toxic substances. Also visual information of a food product is essential in the choice and the acceptance of food products, whereas auditory information obtained during the chewing of crispy products will provide information on whether a product is fresh or stale. Food perception does not just depend on one individual sense, but appears to be the result from multisensory integration of unimodal signals. Large differences in oral physiology parameters exist among individuals, which may lead to differences in food perception. Knowledge of the interplay between mastication and sensory experience for groups of individuals is important for the food industry to control quality and acceptability of their products. Environment factors during eating, like TV watching or electronic media use, may also play a role in food perception and the amount of food ingested. Distraction during eating a meal may lead to disregard about satiety and fullness feelings and thus to an increased risk of obesity. Genetic and social/cultural aspects seem to play an important role in taste sensitivity and food preference. Males generally show larger bite size, larger chewing power and a faster chewing rhythm than females. The size of swallowed particles seems to be larger for obese individuals, although there is no evidence until now of an 'obese chewing style'. Elderly people tend to have fewer teeth and consequently a less good masticatory performance, which may lead to lower intakes of raw food and dietary fibre. The influence of impaired mastication on food selection is still controversial, but it is likely that it may at least cause

'Treats', 'sometimes foods', 'junk': a qualitative study exploring 'extra foods' with parents of young children.

The present study investigated parents' understanding and approaches to providing energy-dense and nutrient-poor 'extra foods' to pre-school children and explored variation between parents of low and high socio-economic status in relation to these issues. We conducted thirteen focus groups. Data were subject to framework analysis. Child-care centres in distinctly socially disadvantaged and socially advantaged areas. Eighty-eight parents of children aged 3-5 years. The three most common terms parents identified to describe foods that are not 'everyday foods' were 'treats', 'sometimes foods' and 'junk'. Parents' perceptions regarding what influences them in providing food to their children included seven sub-themes: (i) the influence of the child; (ii) food-related parenting practices; (iii) health considerations; (iv) food costs and convenience; (v) external factors perceived as influencing their child; (vi) factors related to child care; and (vii) social influences and occasions. Parents' decision-making processes regarding provision of 'extra foods' related to moderation and balance. Parents generally expressed the position that as long as a child is eating healthy foods, then treats are appropriate; and for many parents, this might apply frequently. All groups described the health of their child as an influence, but parents in low socio-economic groups were more likely to describe immediate concerns (dental health, behaviour) in relation to avoiding sugar-dense food or drink. The belief that provision of 'extra foods' can be frequent as long as children are eating a healthy balance of foods is factored into parents' decision making. Challenging this belief may be important for reducing the consumption of 'extra foods' by young children.

The influence of parental food preference and neophobia on children with phenylketonuria (PKU

2018-03-01

Conclusions: In PKU, parental food choices and their food neophobia have limited influence on their children's eating habits. Food neophobia in children with PKU may be associated with fear of eating unfamiliar foods potentially containing a source of protein or aspartame. Their preference for sweet foods may be influenced by limited food choices and habitual consumption of artificially sweetened L-amino acid supplements.

The majority of foods that are consumed in our developed society have been processed. Processing promotes a non-enzymatic reaction between proteins and sugars, the Maillard reaction (MR). Maillard reaction products (MRPs) contribute to the taste, smell and color of many food products, and thus influence consumers’ choices. However, in recent years, MRPs have been linked to the increasing prevalence of diet- and inflammation-related non-communicable diseases including food allergy. Although during the last years a better understanding of immunogenicity of MRPs has been achieved, still only little is known about the structural/chemical characteristics predisposing MRPs to interact with antigen presenting cells (APCs). This report provides a comprehensive review of recent studies on the influence of the Maillard reaction on the immunogenicity and allergenicity of food proteins. PMID:28777346

Most tropical insectivorous birds, unlike their temperate counterparts, hold and defend a feeding and breeding territory year-around. However, our understanding of ecological factors influencing territory selection and size in tropical insectivores is limited. Here we examine three prominent hypotheses relating food abundance, food dispersion (spatial arrangement of food items), and habitat structure to territoriality in the Usambara Thrush Turdus roehli. We first compared leaf-litter macro-invertebrate abundance and dispersion, and habitat structure between territories and random sites. We then examined the relation between these same ecological factors and territory size. Invertebrate abundance and dispersion were sparsely and evenly distributed across our study system and did not vary between territories and random sites. In contrast, habitat structure did vary between territories and random sites indicating the Usambara Thrush selects territories with open understorey and closed overstorey habitat. Invertebrate abundance and dispersion within territories of the Usambara Thrush were not associated with habitat structure. We believe the most likely explanation for the Usambara Thrush’s preference for open understorey and closed overstorey habitat relates to foraging behavior. Using information-theoretic model selection we found that invertebrate abundance was the highest-ranked predictor of territory size and was inversely related, consistent with food value theory of territoriality.

The epidemiology of vector-borne diseases is governed by a structured array of correlative and causative factors, including landscape (for example, rural versus urban), abiotic (for example, weather), and biotic (for example, food web) factors. Studies of mosquito-borne diseases rarely address these multiple factors at large spatial scales, which limits insights into how human alterations of landscapes and food webs alter mosquito abundance. We used structural equation modeling to identify the relative magnitude and direction of landscape, abiotic, and food web factors on Aedes larvae and adults across 70 sites in northern Thailand. Food web factors were modeled as mosquito-predator trophic cascades. Landscape context affected mosquito-predator communities in aquatic and terrestrial environments via cascading food web interactions. Several mosquito predators within these food webs showed potential as biocontrol agents in mosquito population control, but their potentials for control were landscape-dependent. In terrestrial food webs, the habitat-sensitive tokay gecko structured mosquito-predator communities, indicating that a conservation approach to vector control could be a useful addition to existing control efforts.

Lwin, May O; Shin, Wonsun; Yee, Andrew Z H; Wardoyo, Reidinar Juliane

2017-05-01

This study proposes that parental mediation of television advertising and parental guidance of food consumption differentially influence children's attitude, intention, and behavior toward the consumption of healthy and unhealthy foods. Structural equation modeling based on a survey of 1,119 children aged 9-12 supported our model, revealing that parental education strategies influence children's food consumption in a complex manner that is highly context-dependent. Parental guidance of food consumption enhanced children's healthy food attitude and intention to consume, while reducing the intention to consume unhealthy food. However, parental mediation of television advertising influenced unhealthy food attitude to a greater extent than healthy food attitude. Implications for health promotion and education, as well as parents and policy makers are discussed.

The influence of food supply on the response of Olympia oyster larvae to ocean acidification

2013-10-01

Full Text Available Increases in atmospheric carbon dioxide drive accompanying changes in the marine carbonate system as carbon dioxide (CO2 enters seawater and alters ocean pH (termed "ocean acidification". However, such changes do not occur in isolation, and other environmental factors have the potential to modulate the consequences of altered ocean chemistry. Given that physiological mechanisms used by organisms to confront acidification can be energetically costly, we explored the potential for food supply to influence the response of Olympia oyster (Ostrea lurida larvae to ocean acidification. In laboratory experiments, we reared oyster larvae under a factorial combination of pCO2 and food level. Elevated pCO2 had negative effects on larval growth, total dry weight, and metamorphic success, but high food availability partially offset these influences. The combination of elevated pCO2 and low food availability led to the greatest reduction in larval performance. However, the effects of food and pCO2 interacted additively rather than synergistically, indicating that they operated independently. Despite the potential for abundant resources to counteract the consequences of ocean acidification, impacts were never completely negated, suggesting that even under conditions of enhanced primary production and elevated food availability, impacts of ocean acidification may still accrue in some consumers.

Full Text Available The issue of food is indeed a systemic problem involving fundamental aspects of the social, cultural and economic organisation of our planet. This paper focuses on the main aspects related to the concepts of food security and food safety. While the first problem mainly affects less developed countries, the second concerns diet in the developed world. They are influenced by important factors such as the structure of food distribution, the effective access to food resources, the lack of confidence about the safety of the products, and the different consumption behaviours affected by social, economic and religious factors.

Full Text Available This study aimed to analyze the factors that influence consumers in making the decision to buy organic tofu. The theory of factors that influence the purchasing behavior developed by Kotler was used as the analytical tool, and these factors include cultural factors, social factors, personal factors, psychological factors and purchasing process. These data were collected through interview techniques and analyzed descriptively using multinomial logistic regression. The characteristics of respondents indicated the consumers who never bought organic tofu are mostly at the age of 26-35 years old and university graduates, do not work, have an expenditure from Rp 1 million to Rp 2.5 million, are highly knowledge, and have the highest scores on the perceptions on sustainable and environmentally friendly organic farming, health benefits, and a more expensive price. There are a number of factors that influence consumers in making purchase decisions of organic tofu including age, education, knowledge and product external factors. The consumers who are potentially interested in purchasing the organic tofu are at the age of 36–50 years old, university graduates, highly knowledgeable in food and organic tofu products, because the higher the education and knowledge, the greater the interest in buying the products, and they approved of the external products such as price, advertising, personal selling and places of selling which are also potentially equal. The managerial implications for the business agents of tofu organic product is that they must be more active in assuring the consumers that these products are good for them by creating a blog, an ad in the local paper, or a pamphlet containing information of the product.Keywords: purchase decision, logistic regression, organic tofu product, purchasing interest

Food additives, food and the concept of 'food addiction': Is stimulation of the brain reward circuit by food sufficient to trigger addiction?

Onaolapo, A Y; Onaolapo, O J

2018-04-12

In the last few years, the concept of 'food addiction' has continued to gain popularity, with human and animal studies demonstrating the differential effects of foods that are high in fat, sugar or protein on appetite, satiety, eating behaviour and the development of food addiction. However, a number of studies have disputed the occurrence of food addiction in humans. Questions have also arisen regarding the possible impacts that food additives may have on the development of food addiction or eating disorders. Also, it is known that alterations in food composition and the presence of food additives (flavour enhancers, sugars, sugar substitutes, and non-nutritive sweeteners) are factors that generally influence the sensory perception of food. Our understanding of the potential roles of central neurotransmitters (such as dopamine) and certain neuropeptides in the evolution of food addiction is also evolving; but presently, there isn't sufficient scientific evidence to consider any food ingredient, micronutrient or standard food-additive as addictive. In this review, the relevant literatures dealing with the concept of 'food addiction' are examined, and the factors which may predispose to food addiction are discussed. The possible influences that flavour-enhancers, sugars, sugar substitutes and non-nutritive sweeteners may exert on central neurotransmission, neurotransmitter/receptor interactions, appetite, satiety, conditioned- preferences and the brain reward system are also highlighted.

Studies on influence of biological factors on concentration of radionuclides

International Nuclear Information System (INIS)

Anon.

1974-01-01

Biological factors influencing the concentration of radionuclides were studied from the points of uptake through digestive tract, food as pathways, and metabolic activities. The uptake of radionuclides by marine fishes through digestive tract was determined by whole body counter. 137 Cs, 65 Zn, 131 I, 54 Mn, 60 Co, 85 Sr, and 144 Ce were used as tracers and was given with solid feed. The feed given was excreated 24 to 48 hours later in small of middle sized fishes, and 20 to 48 hours later in large sized fishes. The uptake rate of 137 Cs and 65 Zn was high absorption of 20 to 80 per cent, that of 131 I, 60 Co and 54 Mn was not remarkable, and that of 85 Sr and 144 Ce was low absorption. The biological concentration of 137 Cs through pathways of food. In fishes taking up radionuclides through contaminated food, concentration factor increased in accordance with contamination level. In addition, radionuclides with small uptake but delayed excretion and those with high concentration rate could be the factors to decide the concentration factors of marine organisms. In order to study the relationship between metabolic activities and concentration, the uptake of one-year old fishes and adult fishes, and fishes fed and those non-fed were compared. One-year fishes took up large amount of 85 Sr during short period, however, concentration by metabolism in adult fishes was slow. Comparing feeding group and non-feeding group, the former showed 85 Sr concentration factor of 1.5 to 2 times that of the later, and the later showed 137 Cs concentration factor of 2 to 4 times that of the former. However, both uptake and excretion were rapid suggesting that taking food activated the metabolism of substances. (Kanao, N.)

Full Text Available The needs to develop improved varieties of maize have been in the heart of various researchers and institutions in Nigeria because of its strategic role in tackling food insecurity and poverty. Despite substantial efforts to improve maize varieties, the level of adoption of improved maize varieties (IMV in Nigeria in still very low. Although previous adoption studies have indicated a number of socioeconomic and institutional/organizational variables as important factors influencing adoption of improved maize (crop varieties in the country, whether these factors are the main issues of concern, and whether the inclusion of regional/agro-ecological variables in adoption model are also important in explaining what could drive farmers’ adoption behaviour requires investigation. This study therefore examined factors influencing adoption of IMV among farmers in Nigeria using a selected portion of the Nigeria Living Standard Measurement Survey data collected by the National Bureau of Statistics and the World Bank for 2010/2011 cropping season with descriptive statistics and probit model as tools for data analysis. The results suggest, in line with some previous studies, that farm size, education level of farmers and access to extension services would significantly influence adoption of IMV. The results also indicate that farmers across the entire agro-ecological regions of country share some negative sentiments regarding adoption of IMV. Renewed emphasis on interventions that would enable farmers gain more access to farmland, and promote formal education and extension service are advocated. An attempt to incorporate variables that capture farmers’ perception/experience on agroclimatic/ ecologically related concerns in adoption study could aid better understand of what drives farmers’ adoption decisions across the country especially in the light of the emerging climate change issues and its implication on food production.

Introduction Junk food (JF) consumption trend is increasing in all parts of the world. The transition in lifestyle and dietary habits is leading to many non-communicable diseases. The objectives of this study are twofold: (1) To examine the prevalence of junk food consumption and factors associated with consuming junk food among Saudi adults in Jeddah; and (2) to compare the trends of junk food consumption among males and females in Jeddah. Methodology This cross-sectional study was conducted in five different Primary Health Care centers (PHCCs) of Jeddah working under Ministry of Health. The subjects were men (n = 146) and women (n = 254) aged 18-67 years visiting these centers. Structured validated close ended questionnaire was filled by all the participants. Data analysis was done using SPSS. Chi-square was applied to analyze the difference between male and female JF consumption and multivariate logistic regression analysis was done to examine the risk factors. Results Overall the JF consumption in subjects with mean age 33.69 ± 12.29 years was highly prevalent in both genders (86.5%); (men = 85.6% and women = 87.4%). Controlling for some demographic and socioeconomic variables, increased junk food consumption was independently associated with education (OR = 2.47, 95% CI: 1.088-5.605, p = 0.031), individuals who had limited time (OR = 3.82, 95% CI: 1.690-8.642, p junk food consumption among Saudi adults. Junk food has influence in the dietary patterns of Saudi adults and this trend is likely to rise. This growing widespread use of junk food is of concern which may cause obesity-related non-communicable diseases.

Like drug addiction, cues associated with palatable foods can trigger food-seeking, even when sated. However, whether susceptibility to the motivating influence of food-related cues is a predisposing factor in overeating or a consequence of poor diet is difficult to determine in humans. Using a rodent model, we explored whether a highly palatable 'junk food' diet impacts responses to reward-paired cues in a Pavlovian-to-instrumental transfer test, using sweetened condensed milk (SCM) as the reward. The hedonic impact of SCM consumption was also assessed by analyzing licking microstructure. To probe the effects of pattern and duration of junk food exposure, we provided rats with either regular chow ad libitum (controls) or chow plus access to junk food for either 2 or 24 h per day for 1, 3, or 6 weeks. We also examined how individual susceptibility to weight gain related to these measures. Rats provided 24 h access to the junk food diet were insensitive to the motivational effects of a SCM-paired cue when tested sated even though their hedonic experience upon reward consumption was similar to controls. In contrast, rats provided restricted, 2 h access to junk food exhibited a cue generalization phenotype under sated conditions, lever-pressing with increased vigor in response to both a SCM-paired cue, and a cue not previously paired with reward. Hedonic response was also significantly higher in these animals relative to controls. These data demonstrate that the pattern of junk food exposure differentially alters the hedonic impact of palatable foods and susceptibility to the motivating influence of cues in the environment to promote food-seeking actions when sated, which may be consequential for understanding overeating and obesity.

Background Price can influence food purchases, which can influence consumption. Limited laboratory research has assessed the effect of price changes on food purchases, and no research on individual differences that may interact with price to influence purchases exists. Objective We aimed to assess the influence of price changes of low-energy-density (LED) and high-energy-density (HED) foods on mother’s food purchases in a laboratory food-purchasing analogue. Design Mothers were randomly assigned to price conditions in which the price of either LED or HED foods was manipulated from 75% to 125% of the reference purchase price, whereas the price of the alternative foods was kept at the reference value. Mothers completed purchases for 2 income levels ($15 or $30 per family member). Results Purchases were reduced when prices of LED (P elasticity of HED foods and substitution of LED for HED foods.

Bailey, Rachel L

2016-12-01

More energy dense foods are preferable from an optimal foraging perspective, which suggests these foods are more motivationally relevant due to their greater capability of fulfilling biological imperatives. This increase in motivational relevance may be exacerbated in circumstances where foraging will be necessary. This study examined how food energy density and presence of food in the immediate environment interacted to influence motivational processing of food advertisements. N = 58 adults viewed advertisements for foods varying in energy density in contexts where the advertised food was actually present in the viewing room or not. Advertisements for more energy dense foods elicited greater skin conductivity level compared to ads for less energy dense foods when food was not present. All ads elicited decreases in corrugator supercilii activation indicating positive emotional response resultant from appetitive motivational activation, though the greatest activation was exhibited toward higher energy density foods when food was present. This supports an optimal foraging perspective and has implications for healthy eating interventions. Copyright © 2016 Elsevier Ltd. All rights reserved.

Adverse effect on health has been described for a high consumption of energy-dense food, among children and adults. Limited research has been performed among pre-school children. The objective of this study is to evaluate the association between socioeconomic characteristics and family structure, and the consumption of energy-dense food among 2-year-old children. The study sample includes 808 2-year-old children from the Portuguese birth cohort Generation XXI with information on food consumption. Data were obtained from questionnaires administered by interviewers to parents. Based on a food frequency questionnaire, four groups of energy-dense food were defined: soft drinks (sweetened drinks), sweets (chocolate and candies), cakes (creamy and not creamy cakes and sweet pastry) and salty snacks (crisps, pizza and burger). Multinomial logistic regression models (odds ratio and 95% confidence intervals) were fitted to estimate the associations. Intakes of energy-dense food were much lower than in similar aged children in other Westernized countries. Maternal age and education, grandparents' education, household income and maternal occupation were inversely associated with the consumption of energy-dense food, particularly soft drinks and sweets. Children with older siblings were more likely to have a daily consumption of any energy-dense food. Few significant associations were found between socioeconomic characteristics and family structure and consumption of cakes and sweets less than once a week. High socioeconomic characteristics were associated with lower consumption of energy-dense food by 2-year-old children, mainly soft drinks and sweets. This influence is not only from parents' background but also from the preceding generations.

Association between food and nutrition insecurity with cardiometabolic risk factors in childhood and adolescence: a systematic review

2016-06-01

Full Text Available Abstract Objective: To address the association between food and nutrition insecurity and cardiometabolic risk factors in childhood and adolescence. Data source: Articles were selected from the Medline, Lilacs and SciELO databases with no publication date limit, involving children and adolescents, using the descriptors: food and nutrition security, diabetes mellitus, hypertension, metabolic syndrome, stress and dyslipidemia. The terms were used in Portuguese, English and Spanish. The search was carried out systematically and independently by two reviewers. Data synthesis: Exposure to food insecurity during childhood and adolescence ranged from 3.3% to 82% in the selected publications. Exposure to food insecurity was associated with stress, anxiety, greater chance of hospitalization, nutritional deficiencies, excess weight and inadequate diets with reduced intake of fruits and vegetables and increased consumption of refined carbohydrates and fats. Conclusions: Food and nutrition insecurity was associated with the presence of cardiometabolic risk factors in the assessed publications. Childhood and adolescence constitute a period of life that is vulnerable to food insecurity consequences, making it extremely important to ensure the regular and permanent access to food. Because this is a complex association, some difficulties are found, such as the synergy between risk factors, the assessment of heterogeneous groups and extrapolation of data to other populations, in addition to the influence of environmental factors.

Little is known about the dynamics of the food outlet distributions associated with local contextual factors in the U.S. This study examines the changes in food stores/services at the 5-digit Zip Code Tabulated Area (ZCTA5) level in the U.S., and assesses contextual factors associated with the changes. Data from 27,878 ZCTA5s in the contiguous United States without an extreme change in the number of 6 types of food stores/services (supermarkets, small-size grocery stores, convenience stores, fresh/specialty food markets, carry-out restaurants, and full-service restaurants) were used. ZCTA5s' contextual factors were from the 2000 Census. Numbers of food stores/services were derived from the Census Business Pattern databases. Linear regression models assessed contextual factors' influences (racial/ethnic compositions, poverty rate, urbanization level, and foreign-born population%) on 1-year changes in food stores/services during 2000-2001, adjusted for population size, total business change, and census regions. Small-size grocery stores and fresh/specialty food markets increased more and convenience stores decreased more in Hispanic-predominant than other areas. Among supermarket-free places, new supermarkets were less likely to be introduced into black-predominant than white-predominant areas (odds ratio (OR) = 0.52, 95% CI = 0.30-0.92). However, among areas without the following type of store at baseline, supermarket (OR = 0.48 (0.33-0.70)), small-size grocery stores (OR = 1.32 (1.08-1.62)), and fresh/specialty food markets (OR = 0.70 (0.53-0.92)) were less likely to be introduced into areas of low foreign-born population than into areas of high foreign-born population. Higher poverty rate was associated with a greater decrease in supermarket, a less decrease in small-size grocery stores, and a less increase in carry-out restaurants (all p for trends restaurants than suburban areas.

Previous research has identified convenience, enjoyment, value for money and perceived goodness as primary dimensions of parents' attitudes to foods and beverages. The aim of the present study was to examine the factors associated with parents' scores on each of these attitudinal dimensions to identify key issues for future interventions designed to improve parents' food provision behaviours and children's diets. A sample of 1302 Australian parents of children aged 8 to 14 years completed an online survey relating to their food-related beliefs. Linear regression analyses were undertaken to examine factors associated with parents' attitudes to soft drinks and energy-dense nutrient-poor foods. Consistent factors were identified for both energy-dense, nutrient-poor foods and soft drinks, indicating that similar approaches could be adopted in interventions for both product categories. The primary factors were social norms, child pestering, television viewing and exposure to food advertising. Food advertising represents a common link between the primary factors, indicating that it constitutes a critical component of future interventions designed to modify parents' attitudes to unhealthy food products and to reduce the frequency with which these foods are consumed by children. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Full Text Available Closing the health gap between Indigenous and non-Indigenous Australians relies, in part, on addressing the poor levels of nutrition in remote Indigenous communities (RIC. This article identifies and maps key influencers of food choice at the point-of-purchase (POP in Australian RIC and identifies gaps in our knowledge. It is based on a narrative review of the literature pertaining to food in RIC from a range of disciplinary perspectives including nutrition, ethnography, public health, anthropology, and remote health to map POP drivers of food choice. In particular, the role of habit is identified as a key factor that has previously not been discussed in the literature. The conceptual framework can be used as a basis for future POP research in RIC and provides guidance for social marketers, public health, nutrition, and policy workers operating in this field.

Influence of functional food components on gut health.

Science.gov (United States)

Wan, Murphy L Y; Ling, K H; El-Nezami, Hani; Wang, M F

2018-01-30

Intestinal epithelial cells (IECs) lining the gastrointestinal tract establish a barrier between external environments and the internal milieu. An intact intestinal barrier maintains gut health and overall good health of the body by preventing from tissue injury, pathogen infection and disease development. When the intestinal barrier function is compromised, bacterial translocation can occur. Our gut microbiota also plays a fundamentally important role in health, for example, by maintaining intestinal barrier integrity, metabolism and modulating the immune system, etc. Any disruption of gut microbiota composition (also termed dysbiosis) can lead to various pathological conditions. In short, intestinal barrier and gut microbiota are two crucial factors affecting gut health. The gastrointestinal tract is a complex environment exposed to many dietary components and commensal bacteria. Dietary components are increasingly recognized to play various beneficial roles beyond basic nutrition, resulting in the development of the functional food concepts. Various dietary modifiers, including the consumption of live bacteria (probiotics) and ingestible food constituents such as prebiotics, as well as polyphenols or synbiotics (combinations of probiotics and prebiotics) are the most well characterized dietary bioactive compounds and have been demonstrated to beneficially impact the gut health and the overall well-being of the host. In this review we depict the roles of intestinal epithelium and gut microbiota in mucosal defence responses and the influence of certain functional food components on the modulation of gut health, with a particular focus on probiotics, prebiotics and polyphenols.

[Bioavailability and factors influencing its rate].

Science.gov (United States)

Vraníková, Barbora; Gajdziok, Jan

Bioavailability can be defined as the rate and range of active ingredient absorption, when it becomes available in the systemic circulation or at the desired site of drug action, respectively. Drug bioavailability after oral administration is affected by anumber of different factors, including physicochemical properties of the drug, physiological aspects, the type of dosage form, food intake, biorhythms, and intra- and interindividual variability of the human population. This article is the first from the series dealing with the bioavailability and methods leading to its improvement. The aim of the present paper is to provide an overview of aspects influencing the rate of bioavailability after oral administration of the active ingredient. Subsequentarticles will provide detailed descriptions of methods used for dug bioavailability improvement, which are here only summarized.

Influence of social norms and palatability on amount consumed and food choice.

Science.gov (United States)

Pliner, Patricia; Mann, Nikki

2004-04-01

In two parallel studies, we examined the effect of social influence and palatability on amount consumed and on food choice. In Experiment 1, which looked at amount consumed, participants were provided with either palatable or unpalatable food; they were also given information about how much previous participants had eaten (large or small amounts) or were given no information. In the case of palatable food, participants ate more when led to believe that prior participants had eaten a great deal than when led to believe that prior participants had eaten small amounts or when provided with no information. This social-influence effect was not present when participants received unpalatable food. In Experiment 2, which looked at food choice, some participants learned that prior participants had chosen the palatable food, others learned that prior participants had chosen the unpalatable food, while still others received no information about prior participants' choices. The social-influence manipulation had no effect on participants' food choices; nearly all of them chose the palatable food. The results were discussed in the context of Churchfield's (1995) distinction between judgments about matters of fact and judgments about preferences. The results were also used to illustrate the importance of palatability as a determinant of eating behavior.

2018-03-01

In a previous case-control study, we demonstrated that children with PKU and non-PKU controls preferred sweet foods. Additionally, children with PKU exhibited food neophobia, with no preference for bitter tasting foods associated with the taste of phenylalanine (Phe)-free L-amino acid supplements. In an observational extension study, we evaluated the influence of parental food choice and neophobia on their children's taste preferences and food neophobia. Male and female parents/caregivers of 35 children with PKU and 35 control parents, completed a neophobia and food frequency questionnaire for comparison using the same questionnaires that they completed for their children. Both groups of children (PKU and non PKU control) were rated as more food neophobic and exhibited more neophobic behaviour than parents, although children with PKU more so than non-PKU controls (PKU food neophobia p foods such as bread and pasta, and more sweet snacks such as biscuits than their parents. Non-PKU control children's food choices were closer to their parent's choices. In PKU, parental food choices and their food neophobia have limited influence on their children's eating habits. Food neophobia in children with PKU may be associated with fear of eating unfamiliar foods potentially containing a source of protein or aspartame. Their preference for sweet foods may be influenced by limited food choices and habitual consumption of artificially sweetened L-amino acid supplements.

2016-10-01

To assess the influence of brand equity characters displayed on food packaging on children's food preferences and choices, 2 studies were conducted. Brand equity characters are developed specifically to represent a particular brand or product. Despite existing literature suggesting that promotional characters influence children's food choices, to date, no research has assessed the influence of brand equity characters specifically. We recruited 209 children 4-8 years of age from schools and childcare centers in the UK. In a mixed-measures design, the children were asked to rate their taste preferences and preferred snack choice for 3 matched food pairs, presented either with or without a brand equity character displayed on packaging. Study 1 addressed congruent food-character associations and study 2 addressed incongruent associations. Participants were also asked to rate their recognition and liking of characters used. Wilcoxon signed-rank tests and χ(2) analyses were used where appropriate. Children were significantly more likely to show a preference for foods with a brand equity character displayed on the packaging compared with a matched food without a brand equity character, for both congruent and incongruent food-character associations. The presence of a brand equity character also significantly influenced the children's within-pair preferences, within-pair choices, and overall snack choice (congruent associations only). Displaying brand equity characters promotes unhealthy food choices in children. The findings are consistent with those of studies exploring other types of promotional characters. In the context of a childhood obesity epidemic, the use of brand equity characters in the promotion of foods high in fat, salt, and sugar to children should be restricted.

A preceding study revealed much difference among a selected number of radioisotopes in the passing of the food chains. The present study confirms the possibility to reduce radioactivity intake by a careful food choice. The physiology of metabolism of /sup 131/I, /sup 90/Sr and /sup 137/Cs, and other radionuclides is shortly recapitulated. Discrimination and speciation are seen to be main factors in reduction or enrichment in animal food products. Several calculations are given relating intake of radioactivity and food sources. Risk factors are mentioned, as well as the psychology around them. Although it is not urgent, it seems possible to reduce the intake of radioactivity by individuals, mainly by preference for animal products (except milk during the first weeks of a nuclear incident), and by consumption of refined food instead of 'health products'. For mankind as a whole, the popular conceptions about risk and health food need to be studied first and to be redressed, eventually. 13 refs.; 1 figure; 3 tabs.

Objective: To study the influence of diet and behavior related factors on the peripheral blood triglyceride levels in adults, through a cross-sectional survey. Methods: The current study included 13 434 subjects without histories of major chronic diseases from a population-based cross-sectional survey: the 2010 Metabolic Syndrome Survey in Zhejiang Province. A generalized linear model was used to investigate the influence of diet/behavior-related factors on the peripheral blood triglyceride levels. Results: Mean TG of the sample population appeared as (1.36±1.18) mmol/L. The proportions of elevated TG and marginally elevated TG were 10.3% and 11.0% respectively, with statistically significant difference seen between males and females ( χ (2)=44.135, P smoking, alcohol-intake, meat, fruit and water intake in male population from this study. However, in females, the intake of aquatic product and physical exercise showed statistically significant differences. After controlling for other variables, factors as age, drinking, staple food and aquatic products showed positive influence on TG, while milk presented negative influence on TG. Through interaction analysis, fruit and meat intake in males and staple food in females showed positive influence on TG, when compared to the reference group. Conclusion: Hyperglyceridemia appeared as one of the major metabolic abnormities in Zhejiang province. Programs on monitoring the alcohol, staple food and meat intake should be priority on intervention, in the communities.

Concentrations of organochlorine pesticides and stable isotope ratios of nitrogen and carbon were measured in a tropical freshwater ecosystem to evaluate the contamination level of biota and examine the bioaccumulation patterns of pollutants through the food web. Chemical analyses showed a general and heavy contamination of the entire food web. They revealed the strong accumulation of pollutants by juveniles of diadromous fishes and shrimps, as they re-enter the river. The role of ecological factors in the bioaccumulation of pesticides was evaluated. Whereas the most persistent pollutants (chlordecone and monohydro-chlordecone) were related to the organisms diet and habitat, bioaccumulation of {beta}-HCH was only influenced by animal lipid content. The biomagnification potential of chlordecone through the food chain has been demonstrated. It highlighted the importance of trophic transfer in this compound bioaccumulation process. In contrast, bioconcentration by passive diffusion from water seemed to be the main exposure route of biota to {beta}-HCH. - Highlights: > We measured OC pesticides and stable isotope ratios in a tropical stream. > Results showed a strong and ubiquitous contamination of the entire food web. > Diadromous juveniles strongly accumulated pollutants when they re-enter the river. > The most persistent pollutant (chlordecone) was related to species diet and habitat. > {beta}-HCH was only influenced by animal lipid content. - This paper determines the bioaccumulation and transfer processes of organochlorine pesticides within the stream food web in Guadeloupe (Caribbean).

Convenience-based food purchase patterns: identification and associations with dietary quality, sociodemographic factors and attitudes.

Peltner, Jonas; Thiele, Silke

2018-02-01

The present study aimed to derive food purchase patterns considering the convenience level of foods. Associations between identified patterns and dietary quality were analysed, as well as household characteristics associated with the dietary patterns. A Convenience Food Classification Scheme (CFCS) was developed. After classifying basic food groups into the CFCS, the formed groups were used to apply a factor analysis to identify convenience-based food purchase patterns. For these patterns nutrient and energy densities were examined. Using regression analysis, associations between the adherence to the patterns and household characteristic and attitude variables were analysed. The study used representative German food purchase data from 2011. Approximately 12 million purchases of 13 131 households were recorded in these data. Three convenience-based patterns were identified: a low-convenience, a semi-convenience and a ready-to-eat food pattern. Tighter adherence to the semi-convenience pattern was shown to result in the lowest nutrient and highest energy densities. Important factors influencing adherence to the patterns were household size, presence of children and attitudes. Working full-time was negatively associated with adherence to the low-convenience pattern and positively with the ready-to-eat pattern. Convenience foods were an important part of households' food baskets which in some cases led to lower nutritional quality. Therefore, it is important to offer convenience foods higher in nutrient density and lower in energy density. Interventions targeted on enhancing cooking skills could be an effective strategy to increase purchases of unprocessed foods, which, in turn, could also contribute to an improved diet quality.

Utilization of essential oils (EOs) as antimicrobial agents against foodborne disease has gained importance, for their use as natural preservatives. Since potential interactions between EOs and food characteristics may affect their antimicrobial properties, the present work studies the influence of fat, protein, pH, a w and food additives on the antimicrobial effect of oregano and garlic EOs against Salmonella spp. and Listeria monocytogenes. Results showed that protein, pH, a w , presence of beef extract, sodium lactate and nitrates did not influence their antimicrobial effect. In contrast, the presence of pork fat had a negative effect against both EOs associated with their dilution of the lipid content. The addition of food phosphates also exerts a negative effect against EOs probably associated with their emulsification properties as observed with the addition of fat. The results may help the food industry to select more appropriate challenges to guarantee the food safety of foodstuffs.

Factors affecting food handling Practices among food handlers of Dangila town food and drink establishments, North West Ethiopia

Science.gov (United States)

2014-01-01

Background Food borne diseases are major health problems in developed and developing countries including Ethiopia. The problem is more noticeable in developing countries due to prevailing poor food handling and sanitation practices, inadequate food safety laws, weak regulatory systems, lack of financial resources to invest on safer equipments, and lack of education for food handlers. Methods The objective of this study was to assess food handling practice and associated factors among food handlers working in food and drinking establishments of Dangila town, North West Ethiopia. Cross-sectional quantitative study design was conducted among 406 food handlers working in 105 food and drink establishments from July to August 2013 in Dangila town. Data were collected using face to face interview with pretested structured questionnaire and physical observation. Result The mean age of the respondents was 22.7 ± 4.2 years of which 62.8% of the food handlers were females. Two hundred thirteen (52.5%) of food handlers had good food handling practices. Marital status (AOR = 7.52, 95% CI, 1.45-38.97), monthly income (AOR = 0.395, 95% CI, 0.25-0.62), knowledge about food handling (AOR = 1.69, 95% CI, 1.05-2.73), existence of shower facility (AOR = 1.89, 95% CI, 1.12-3.21) and separate dressing room (AOR = 1.97, 95% CI, 1.11-3.49) were found to be significantly associated with good food handling Practices. Conclusion Above half of food handlers had good food handling practices. Marital status, monthly income, knowledge status, existence of shower facility, existence of separate dressing room and presence of insect and rodent were factors associated with food handling Practices.

Full Text Available Many species of primates are considered seasonal breeders, but the set of factors, such as food availability, day length and temperature, that influence the timing of reproductive events for both wild and captive individuals remains unclear. Here, we examine the role of factors in shaping breeding patterns in Rhinopithecus roxellana, a temperate colobine primate. We used circular statistics to describe and compare the patterns of reproductive seasonality among individuals in 13 captive groups and two free ranging but provisioned groups at various locations throughout China. Almost 90% of births occurred in March, April and May in adult females residing in both free ranging (n = 131 and captive groups (n = 407. Births occurred principally in 2–4 months prior to the peak of food availability, while conceptions occurred in 1–2 months after the peak of food availability in free ranging but provisioned groups. Day length (latitude had a significant effect on the timing of reproduction. However, females that experienced a wide variation of temperature between the lowest and highest monthly average temperature had a later conception date. These results support that day length and temperature might be factor influencing the timing of reproductive activity.

Elbel, B; Gyamfi, J; Kersh, R

2013-01-01

Objective Obesity is an enormous public health problem and children have been particularly highlighted for intervention. Of notable concern is the fast-food consumption of children. However, we know very little about how children or their parents make fast-food choices, including how they respond to mandatory calorie labeling. We examined children’s and adolescents’ fast-food choice and the influence of calorie labels in low-income communities in New York City (NYC) and in a comparison city (Newark, NJ). Design Natural experiment: Survey and receipt data were collected from low-income areas in NYC, and Newark, NJ (as a comparison city), before and after mandatory labeling began in NYC. Study restaurants included four of the largest chains located in NYC and Newark: McDonald’s, Burger King, Wendy’s and Kentucky Fried Chicken. Subjects A total of 349 children and adolescents aged 1–17 years who visited the restaurants with their parents (69%) or alone (31%) before or after labeling was introduced. In total, 90% were from racial or ethnic minority groups. Results We found no statistically significant differences in calories purchased before and after labeling; many adolescents reported noticing calorie labels after their introduction (57% in NYC) and a few considered the information when ordering (9%). Approximately 35% of adolescents ate fast food six or more times per week and 72% of adolescents reported that taste was the most important factor in their meal selection. Adolescents in our sample reported that parents have some influence on their meal selection. Conclusions Adolescents in low-income communities notice calorie information at similar rates as adults, although they report being slightly less responsive to it than adults. We did not find evidence that labeling influenced adolescent food choice or parental food choices for children in this population. PMID:21326209

Revisiting the Economic Factors which Influence Fast Food South African Small, Medium and Micro Enterprise Sustainability

Directory of Open Access Journals (Sweden)

Bruce MASAMA

2018-03-01

Full Text Available In order to stimulate both developing economies and developed economies around the globe policy makers have, over the years, focused their attention to Small, Medium and Micro Enterprises (SMMEs. These business entities are often regarded as the lifeblood of economies around the globe however SMMEs are reported to have high failure rates. For example, in a South African dispensation, the failure rate of SMMEs is considered to be among the worst in the world as approximately 75% fail within a period of 42 months after opening. Through research in the early-2000s, the cause of the excessive South African SMMEs failure rate has been pinned on a plethora of micro-economic factors and macro-economic factors. Over the years the list of economic factors which adversely influence the sustainability of South African SMMEs have not changed drastically, which may well probably explain the high failure rate of these business entities in more recent times. Thus, for this paper, empirical research was conducted to ascertain the extent to which 24 economic factors adversely influence the sustainability of South African SMMEs. Quantitative data were obtained from 116 members of management of South African SMMEs and stemming from the results, it was found that these economic factors still have a reasonable adverse influence on the sustainability of these business entities.

Factors influencing behavior in the forced swim test

Bogdanova, Olena V.; Kanekar, Shami; D’Anci, Kristen E.; Renshaw, Perry F.

2017-01-01

The forced swim test (FST) is a behavioral test in rodents which was developed in 1978 by Porsolt and colleagues as a model for predicting the clinical efficacy of antidepressant drugs. A modified version of the FST added the classification of active behaviors into swimming and climbing, in order to facilitate the differentiation between serotonergic and noradrenergic classes of antidepressant drugs. The FST is now widely used in basic research and the pharmaceutical screening of potential antidepressant treatments. It is also one of the most commonly used tests to assess depressive-like behavior in animal models. Despite the simplicity and sensitivity of the FST procedure, important differences even in baseline immobility rates have been reported between different groups, which complicate the comparison of results across studies. In spite of several methodological papers and reviews published on the FST, the need still exists for clarification of factors which can influence the procedure. While most recent reviews have focused on antidepressant effects observed with the FST, this one considers the methodological aspects of the procedure, aiming to summarize issues beyond antidepressant action in the FST. The previously published literature is analyzed for factors which are known to influence animal behavior in the FST. These include biological factors, such as strain, age, body weight, gender and individual differences between animals; influence of preconditioning before the FST: handling, social isolation or enriched environment, food manipulations, various kinds of stress, endocrine manipulations and surgery; schedule and routes of treatment, dosage and type of the drugs as well as experimental design and laboratory environmental effects. Consideration of these factors in planning experiments may result in more consistent FST results. PMID:23685235

2018-07-01

Previous evidence showed the presence of a straight relationship between feeding behavior and emotions. Despite that, no studies have focused on the influence of emotional faces on food processing. In our study, participants were presented with 72 couples of visual stimuli composed of a neutral, happy, or disgusted faces (5000 ms duration in Experiment 1, adaptation; 150 ms in Experiment 2, priming) followed by a food stimulus (1500 ms). Food stimuli were grouped in pleasant foods, further divided in natural and transformed, and unpleasant rotten foods. The task consisted in judging the food valence (as 'pleasant' or 'unpleasant') by keypress. Results showed a different pattern of response based on the transformation level of food. In general, the evaluation of natural foods was more rapid compared with transformed foods, maybe for their simplicity and healthier perception. In addition, transformed foods yielded incongruent responses with respect to the preceding emotional face, whereas natural foods yielded congruent responses with respect to it. These effects were independent of the duration of the emotional face (i.e., adaptation or priming paradigm) and may depend on pleasant food stimuli salience.

The influence of parents versus friends on youths' eating behavior has not been directly compared, and little is known about the developmental effects of social influences on their eating behavior. The objective was to compare the effects of mothers and friends on children's and adolescents' energy intake from sandwiches and from healthy and unhealthy snacks and dessert foods. Twenty-three children (ages 5-7 y) and 27 adolescents (ages 13-15 y) ate a meal with their mother on one occasion and with a same-sex friend on another occasion. Male and female children consumed less energy from unhealthy snacks when in the presence of their mothers than when in the company of their friends. Conversely, female adolescents consumed less energy from unhealthy snacks and more energy from healthy snacks when they were with their friends than when with their mothers. Food selection is differentially influenced by the source of social influence and the age and sex of the child. Parents may act as an inhibitory influence on unhealthy eating for younger children. Adolescent girls may try to convey a good impression of healthy eating when eating with same-sex friends, but the eating habits of teenage boys are not as influenced by the social context. This trial is registered at clinicaltrials.gov as NCT00875576.

To apply the traditional method in pest control it is needed to know the reaction capability of the insect in reference to radiations as well as the influence which can be exerted over it by different factors. The radiosensitivity of Spodoptera Frugiperda Smith Abbot larvae raised with two different diets (natural and artificial) was studied using doses between 20 and 100 Gy, in Co-60 gamma source with a dose power of 13.4 Gy/min survival, formation and dimensions of pupas, adult emergency and other interesting aspects were determined. The multiple analysis of results showed the influence of the food diet on radiosensitivity of larvae. results of both diets are statistically compared

To investigate how food commercials influence children's food choices. Twenty-three children ages 8-14 years provided taste and health ratings for 60 food items. Subsequently, these children were scanned with the use of functional magnetic resonance imaging while making food choices (ie, "eat" or "not eat") after watching food and nonfood television commercials. Our results show that watching food commercials changes the way children consider the importance of taste when making food choices. Children did not use health values for their food choices, indicating children's decisions were largely driven by hedonic, immediate rewards (ie, "tastiness"); however, children placed significantly more importance on taste after watching food commercials compared with nonfood commercials. This change was accompanied by faster decision times during food commercial trials. The ventromedial prefrontal cortex, a reward valuation brain region, showed increased activity during food choices after watching food commercials compared with after watching nonfood commercials. Overall, our results suggest watching food commercials before making food choices may bias children's decisions based solely on taste, and that food marketing may systematically alter the psychological and neurobiologic mechanisms of children's food decisions.

This study describes and evaluates the influence of income on the percentage of food expenditures away from home for Brazilian families. Food acquisition data from the National Household Budget Survey conducted from 2002 to 2003 (POF 2002/2003) by the Brazilian Institute of Geography and Statistics (IBGE) or National Census Bureau was used in the analysis. Information on food-and-drink expenditures away from home was analyzed. The influence of income on the share of food purchased away from home in the household budget, adjusted for socio-demographic variables, was analyzed through elasticity coefficients estimated in multiple linear regression. Food purchased away from home accounted for 21% of total food expenditures by Brazilian households. A 10% increase in income increased the share of food purchased away from home by 3%. Income elasticity was high, especially for the lowest income families. The results demonstrate an important influence of income on food expenditures away from home, and higher income is associated with a greater share of food purchased away from home.

Stress and food allergy: mechanistic considerations.

Science.gov (United States)

Schreier, Hannah M C; Wright, Rosalind J

2014-04-01

Recent years have seen a marked increase in food allergy prevalence among children, particularly in Western countries, that cannot be explained by genetic factors alone. This has resulted in an increased effort to identify environmental risk factors underlying food allergies and to understand how these factors may be modified through interventions. Food allergy is an immune-mediated adverse reaction to food. Consequently, considerations of candidate risk factors have begun to focus on environmental influences that perturb the healthy development of the emerging immune system during critical periods of development (eg, prenatally and during early childhood), particularly in the gut. Given that psychosocial stress is known to play an important role in other allergic and inflammatory diseases, such as asthma, its potential role in food allergy is a growing area of research. However, research to date has largely focused on animal studies. This review synthesizes relevant animal research and epidemiological data, providing proof of concept for moderating influences of psychological stress on food allergy outcomes in humans. Pathways that may underlie associations between psychosocial stress and the expression of food allergy are discussed. Copyright © 2014 American College of Allergy, Asthma & Immunology.

Full Text Available Morphological characteristics of the digestive systems in birds are direct reflection of evolutionary adaptations of these animals to different type and way of diet. The research conducted on domestic and some wild birds indicate that besides the evolutionary factors, time of start of food intake after the hatching, and amount and composition of food in the period of intensive growth also influence morphological characteristics of digestive systems in birds. The aim of this study was to determine the influence of extensive and intensive way of farming, and different types and amount of food on the morphometric characteristics of the small and large intestines in 45 broiler turkeys (BIG BUT 600. Statistical analysis shows that the way of breeding and the type and quantity of food all have significant impact on the body weight in turkeys but do not influence the length of the intestinal tract in these animals.Key words: turkey, digestive system, morphology

Observance of the hunger-obesity paradox in urban Minnesota has ignited interest in the quality of low-income households' food purchases. This cross-sectional study investigated low-income, urban Minnesotan women's past-month food purchases and their associations with race, homelessness, and aspects of the food system, including food shelf (ie, food pantry) and food store usage, factors believed to influence food choice and grocery shopping behavior. The survey included demographics, the US Department of Agriculture's 18-item Household Food Security Survey Module, and grocery shopping questions related to food purchases and food stores visited in the past month. Participants were a convenience sample of 448 low-income, urban Minnesotan women, and data were collected from February through May 2008. The sample was 44% African American, 35% American Indian, 10% white, and 11% other/mixed race; 37% were homeless. Rates of "less healthy" food group purchases were higher compared to "healthy" food group purchases.

Childhood food allergy and asthma rates are increasing. The hygiene hypothesis has been proposed as an explanation for the increased incidence of allergic disease. To describe the association of childhood food allergy and asthma with hygiene factors, such as the number of siblings, antibiotic use, infection history, pet exposure, child care exposure, and maternalchild factors. Children ages 021 years old (N = 1359) were recruited for a cross-sectional family-based study, including children with food allergy and children without food allergy, and their siblings. We assessed the associations between childhood food allergy and asthma with hygiene factors. Of the 1359 children, 832 (61.2%) had food allergy, and 406 (30%) had asthma. In the adjusted analysis, the prevalence of food allergy was increased if there was a history of skin infection (prevalence ratio [RRR] 1.12 [95% confidence interval {CI}, 1.011.24]) or eczema (RRR 1.89 [95% CI, 1.702.10]). The prevalence of asthma was increased with a history of respiratory syncytial virus infection (RRR 1.60 [95% CI, 1.341.90]) or eczema (RRR 1.54 [95% CI, 1.271.86]). A greater number of siblings were associated with a decreased prevalence of food allergy (RRR 0.79 [95% CI, 0.750.84]) and asthma (RRR 0.82 [95% CI, 0.740.91]). Our findings supported the accumulating evidence of an association between skin infections and eczema with food allergy. Because these results could be subject to recall bias, additional prospective studies are needed to substantiate these findings.

Full Text Available Food banks provide supplemental food to low-income households, yet little is known about the cardiovascular health of food banks members. This study therefore described cardiovascular disease (CVD risk factors among food bank members and explored associations between food insecurity and CVD risk.Adults ≥18 years (n = 77 from three food bank sites in metro Vancouver, British Columbia completed surveys and physical assessments examining a range of socio-demographic variables and CVD risk factors. A composite measure of myocardial infarction (MI risk called the INTERHEART score was assessed and household food insecurity was measured using the Household Food Security Survey Module. Regression models were used to explore associations between food insecurity and CVD risk measures, including the INTERHEART score.Ninety-seven percent of food bank members reported experiencing food insecurity, 65% were current smokers, 53% reported either chronic or several periods of stress in the past year, 55% reported low physical activity levels and 80% reported consuming fewer than five servings of fruit and vegetables daily. Prevalence of self-reported diabetes and hypertension were 13% and 29% respectively. Fifty-two percent of the sample were at high risk of non-fatal MI. No statistically significant associations were found between increased severity of food insecurity and CVD risk factors among this sample where both severe food insecurity and high CVD risks were prevalent.Food bank members were at elevated risk for CVD compared with the general population. Strategies are needed to reduce prevalence of food insecurity and CVD risk factors, both of which disproportionately affected food bank members.

This study focuses on understanding factors that influence food agency in the Spanish population, specifically with regard to cooking habits, knowledge, and determinants and their possible relationship with body weight. A cross-sectional telephone survey was conducted. Individuals were asked about their cooking responsibilities, how they learned to cook, factors that affect their food choices, and their preferred cooking techniques. Anthropometric data were also recorded. Participants were randomly selected, and we finally had 2026 respondents aged ≥18 years (60% women, 40% men). A total of 90.5% of participants stated that they had cooking skills. Women were mainly responsible for cooking tasks (p cook” in comparison with groups over 50 years. Regardless of age, most participants learned to cook either by practice (43.3%) or from a family member (42.2%). Men tended to be more autodidactic, whereas women reported learning from family. No relation was found between weight status and the evaluated factors investigated. In conclusion, women bear the responsibility for the entire cooking process in families, indicating a gender gap in the involvement of men in cooking responsibilities and competence. More research is needed to assess the influence of cooking knowledge on obesity prevention. PMID:29462887

2014-01-01

Background Little is known about the dynamics of the food outlet distributions associated with local contextual factors in the U.S. This study examines the changes in food stores/services at the 5-digit Zip Code Tabulated Area (ZCTA5) level in the U.S., and assesses contextual factors associated with the changes. Methods Data from 27,878 ZCTA5s in the contiguous United States without an extreme change in the number of 6 types of food stores/services (supermarkets, small-size grocery stores, convenience stores, fresh/specialty food markets, carry-out restaurants, and full-service restaurants) were used. ZCTA5s’ contextual factors were from the 2000 Census. Numbers of food stores/services were derived from the Census Business Pattern databases. Linear regression models assessed contextual factors’ influences (racial/ethnic compositions, poverty rate, urbanization level, and foreign-born population%) on 1-year changes in food stores/services during 2000–2001, adjusted for population size, total business change, and census regions. Results Small-size grocery stores and fresh/specialty food markets increased more and convenience stores decreased more in Hispanic-predominant than other areas. Among supermarket-free places, new supermarkets were less likely to be introduced into black-predominant than white-predominant areas (odds ratio (OR) = 0.52, 95% CI = 0.30-0.92). However, among areas without the following type of store at baseline, supermarket (OR = 0.48 (0.33-0.70)), small-size grocery stores (OR = 1.32 (1.08-1.62)), and fresh/specialty food markets (OR = 0.70 (0.53-0.92)) were less likely to be introduced into areas of low foreign-born population than into areas of high foreign-born population. Higher poverty rate was associated with a greater decrease in supermarket, a less decrease in small-size grocery stores, and a less increase in carry-out restaurants (all p for trends <0.001).

Hardcastle, Sarah J; Blake, Nicola

2016-01-01

The purpose of this qualitative study was to explore the perceptions and attitudes that underlie food choices, and, the impact of a school-based healthy eating intervention in mothers from an economically-disadvantaged community. The aim of the intervention was to educate children to act as 'health messengers' to their families. Sixteen semi-structured phone interviews were conducted with mothers with four receiving a second interview. Interviews were conducted following their child's participation in a six-week after school healthy cooking intervention. Thematic content analysis revealed four main themes: Cost and budget influence on food choices, diversity in household rules controlling food, role of socialisation on diet, and improved cooking skills and confidence to make homemade meals. The interview findings demonstrated the positive influence of the after-school cooking intervention on children and their families in cooking skills, promoting healthier cooking methods and increasing confidence to prepare homemade meals. The findings demonstrated the wider economic and social influences on food choices and eating practices. Socialisation into, and strong cultural norms around, eating habits were significant influences on family diet and on parental decisions underpinning food choices and attitudes towards the control of food within the family. The intervention was perceived to be successful in terms of improving nutritional knowledge, cooking skills and increasing confidence to make healthy and tasty homemade meals. The study demonstrates the importance of parental involvement in school-based interventions if improvements in healthy eating are to be evidenced at the family level and maintained.

Zenk, Shannon N; Horoi, Irina; McDonald, Ashley; Corte, Colleen; Riley, Barth; Odoms-Young, Angela M

2014-12-01

This study examined contributions of environmental and personal factors (specifically, food availability and expense, daily hassles, self-efficacy, positive and negative affect) to within-person and between-person variations in snack food intake in 100 African American women. Participants were signaled at random five times daily for seven days to complete a survey on a study-provided smartphone. Women reported consuming snack foods at 35.2% of signals. Easier food availability accounting for one's usual level was associated with higher snack food intake. Being near outlets that predominately sell snacks (e.g., convenience stores), while accounting for one's usual proximity to them, was associated with higher snack food intake. Accounting for one's usual daily hassle level, we found that on days with more frequent daily hassles snack food intake was higher. The positive association between within-person daily hassles frequency and snack food intake was stronger when foods were easily available. Public and private policies to curb ubiquitous food availability and mobile health interventions that take into account time-varying influences on food choices and provide real-time assistance in dealing with easy food availability and coping with stressors may be beneficial in improving African American women's day to day food choices.

To examine the influence of food consumption survey duration on estimates of percentage consumers, mean total population intakes and intakes among consumers only and to consider its relevance for public health nutrition and food safety issues. Prospective food consumption survey. A multicentre study in five centres in the European Union-Dublin, Ghent, Helsinki, Potsdam and Rome. Teenage subjects were recruited through schools; 948 (80%) out of 1180 subjects completed the survey. 14-day food diaries were used to collect the food consumption data. For mean total population intakes, 53% of the foods had slopes significantly different to 0 (Pday), these differences were small, with 41% of foods having differences of day and a further 35% having differences of 1-5 g/day. Estimates of percentage consumers based on 3 days and 14 days were 1.9 and 3.6 times the 1-day estimate, respectively. For 72% of foods, at least 50% of non-consumers on day 1 became consumers over the subsequent 13 days. Estimates of mean consumer only intakes based on 3 days and 14 days were 53% and 32% of the 1 day value. In practical terms, survey duration influences estimates of percentage consumers and intakes among consumers only but not mean total population intakes. Awareness of this influence is important for improved interpretation of dietary data for epidemiological studies, development of food-based dietary guidelines and food chemical intakes.

Constructing food choice decisions.

Science.gov (United States)

Sobal, Jeffery; Bisogni, Carole A

2009-12-01

Food choice decisions are frequent, multifaceted, situational, dynamic, and complex and lead to food behaviors where people acquire, prepare, serve, give away, store, eat, and clean up. Many disciplines and fields examine decision making. Several classes of theories are applicable to food decision making, including social behavior, social facts, and social definition perspectives. Each offers some insights but also makes limiting assumptions that prevent fully explaining food choice decisions. We used constructionist social definition perspectives to inductively develop a food choice process model that organizes a broad scope of factors and dynamics involved in food behaviors. This food choice process model includes (1) life course events and experiences that establish a food choice trajectory through transitions, turning points, timing, and contexts; (2) influences on food choices that include cultural ideals, personal factors, resources, social factors, and present contexts; and (3) a personal system that develops food choice values, negotiates and balances values, classifies foods and situations, and forms/revises food choice strategies, scripts, and routines. The parts of the model dynamically interact to make food choice decisions leading to food behaviors. No single theory can fully explain decision making in food behavior. Multiple perspectives are needed, including constructionist thinking.

Maldonado-Simán, Ema; Martínez-Hernández, Pedro Arturo; García-Muñiz, José G.; Cadena-Meneses, José

Food marketing at international and domestic markets has focused on processing systems that improve food safety. The objective of this research is to determine the factors influencing the implementation of the HACCP system in the Mexican meat industry, and to identify the main marketing destination of their products. Only 18.5% of enterprises reports fully operational HACCP in their plants. The main destination of their production in the domestic market is supermarkets, suppliers and distributors and specific niches of the domestic market. Exports are to USA, Japan, Korea and Central America and some niches of the domestic market with requirements of higher quality. The four principal factors that motivate enterprises to adopt HACCP are associated with improvement of plant efficiency and profitability, adoption of good practices, improvement of product quality and waste reduction. It is concluded that Mexican enterprises adopt HACCP to successfully remain and face competition by foreign enterprises in the domestic market and to a lesser extent to compete in the international market.

Food banks provide supplemental food to low-income households, yet little is known about the cardiovascular health of food banks members. This study therefore described cardiovascular disease (CVD) risk factors among food bank members and explored associations between food insecurity and CVD risk. Adults ≥18 years (n = 77) from three food bank sites in metro Vancouver, British Columbia completed surveys and physical assessments examining a range of socio-demographic variables and CVD risk factors. A composite measure of myocardial infarction (MI) risk called the INTERHEART score was assessed and household food insecurity was measured using the Household Food Security Survey Module. Regression models were used to explore associations between food insecurity and CVD risk measures, including the INTERHEART score. Ninety-seven percent of food bank members reported experiencing food insecurity, 65% were current smokers, 53% reported either chronic or several periods of stress in the past year, 55% reported low physical activity levels and 80% reported consuming fewer than five servings of fruit and vegetables daily. Prevalence of self-reported diabetes and hypertension were 13% and 29% respectively. Fifty-two percent of the sample were at high risk of non-fatal MI. No statistically significant associations were found between increased severity of food insecurity and CVD risk factors among this sample where both severe food insecurity and high CVD risks were prevalent. Food bank members were at elevated risk for CVD compared with the general population. Strategies are needed to reduce prevalence of food insecurity and CVD risk factors, both of which disproportionately affected food bank members.

Tourette syndrome (TS) is characterized by waxing and waning motor and vocal tics. Because standard medication often remains unsatisfactory, many patients seek alternative medicine. The aim of this study was to increase experience about the influence of food and drinks in TS. A standardized questionnaire was sent to 887 people recruited from our Tourette outpatient clinic and the German TS self-aid group. Respondents should assess whether 32 different foods influenced their tics. Two hundred twenty-four questionnaires could be used for analyses. A significant positive correlation (tic deterioration) was found for caffeine- and theine-containing drinks such as coke (ptic improvement) was not found. Results from this first survey investigating the influence of special foods and drinks on tics demonstrated that 34% and 47% of responders, respectively, assessed that coffee and coke deteriorate tics. It, therefore, can be speculated that caffeine may further stimulate an already overactive dopaminergic system in TS and thus increases tics. However, from these preliminary data, no further general recommendations regarding special diets and food restrictions can be made.

Massive exposure of children to low-nutrient food advertising combined with the increasing prevalence of obesity have led to growing support for statutory regulations concerning food marketing targeting children. Food and advertising industries lobbies have nevertheless managed to stop such measures in many countries. In this context, civil society support for statutory regulation, especially by parents, is essential. The objective of this study was to describe and analyse factors associated with parents' opinion on the impact and possible banning of food TV advertisements targeting children. An online survey of 2,387 parents of children aged 3 to 17 was conducted in 2013. Associations between parents'opinion on food advertising and their socio-demographic characteristics were analysed by multivariate logistic regressions. The influence of food advertising on children' preferences was perceived by 64.7% of parents, 68.8% of parents were at least occasionally asked by their children to purchase food or beverages seen on television, 43.5% reported that their children influenced their food purchases and 73.7% supported a statutory regulation that would ban advertisements for excessively fatty, salty and sugary beverages and foods during television programmes for children or teenagers. This view was positively associated with high socio-economic status and a high perceived impact of advertising on children's food preferences. Parents support for the ban on television food advertising to children is particularly high in France, especially compared to the USA. This result should influence political decision-making to restrict food marketing targeting young people.

How food valuation and decision-making influence the perception of food is of major interest to better understand food intake behavior and, by extension, body weight management. Our study investigated behavioral responses and spatio-temporal brain dynamics by means of visual evoked potentials (VEPs) in twenty-two normal-weight participants when viewing pairs of food photographs. Participants rated how much they liked each food item (valuation) and subsequently chose between the two alternative food images. Unsurprisingly, strongly liked foods were also chosen most often. Foods were rated faster as strongly liked than as mildly liked or disliked irrespective of whether they were subsequently chosen over an alternative. Moreover, strongly liked foods were subsequently also chosen faster than the less liked alternatives. Response times during valuation and choice were positively correlated, but only when foods were liked; the faster participants rated foods as strongly liked, the faster they were in choosing the food item over an alternative. VEP modulations by the level of liking attributed as well as the subsequent choice were found as early as 135-180ms after food image onset. Analyses of neural source activity patterns over this time interval revealed an interaction between liking and the subsequent choice within the insula, dorsal frontal and superior parietal regions. The neural responses to food viewing were found to be modulated by the attributed level of liking only when foods were chosen, not when they were dismissed for an alternative. Therein, the responses to disliked foods were generally greater than those to foods that were liked more. Moreover, the responses to disliked but chosen foods were greater than responses to disliked foods which were subsequently dismissed for an alternative offer. Our findings show that the spatio-temporal brain dynamics to food viewing are immediately influenced both by how much foods are liked and by choices taken on them

To examine food decision-making priorities for restaurant-type foods at grocery stores and determine whether adding calorie information, as required by federal menu labeling laws, affected decision-making priorities. Natural experiment: intervention and control groups with baseline and follow-up. Regional grocery store chain with 9 locations. Participants (n = 393; mean age, 54.8 ± 15.1 years) were primarily women (71%) and Caucasian (95%). Data were collected before and after calorie information was added to restaurant-type foods at 4 intervention locations. Primary influencers of food selection decision making for restaurant-type foods and frequency of use of nutrition information. Quantitative analysis examined the top 3 influencers of food selections and chi-square goodness of fit test determined whether the calorie labeling intervention changed food decision-making priorities. Qualitative data were used to describe responses. Taste, cost, and convenience were the most frequently reported influencers of restaurant-type food selections; 20% of participants rated calories as influential. Calorie labeling did not affect food selection decision making; 16% of participants in intervention stores noticed calorie labels. Qualitative explanations confirmed these findings. Menu labeling laws increase access to calorie information; however, use of this information is limited. Additional interventions are needed to encourage healthier restaurant-type food selections in grocery stores. Copyright © 2018 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

Jurkowski, Marek K; Bobek-Billewicz, Barbara

2007-01-01

Sleep is a universal phenomenon of human and animal lives, although the importance of sleep for homeo-stasis is still unknown. Sleep disturbances influence many behavioral and physiologic processes, leading to health complications including death. On the other hand, sleep improvement can beneficially influence the course of healing of many disorders and can be a prognostic of health recovery. The factors influencing sleep have different biological and chemical origins. They are classical hormones, hypothalamic releasing and inhibitory hormones, neuropeptides, peptides and others as cytokines, prostaglandins, oleamid, adenosine, nitric oxide. These factors regulate most physiologic processes and are likely elements integrating sleep with physiology and physiology with sleep in health and disorders.

In the scenario of food consumptions, we witness the consumer's growing consideration for the "convenience" attribute. Our study intends to understand the consumer behaviour towards convenience-processed foods by analysing in a single model the role of beliefs, personal traits, social influence and market availability. We applied a Structural Equation Model (SEM) to a representative sample of 426 Italian consumers. The results show a correlation between intention to consume convenience-processed foods and social influence, market availability and several personal traits, suggesting strategies for the development of the convenience food market.

Full Text Available Despite the growth in empirical research on neighborhood environmental characteristics and their influence on children’s diets, physical activity, and obesity, much remains to be learned, as few have examined the relationship between neighborhood food availability on dietary behavior in children, specifically. This analysis utilized data from a community-based, cross-sectional sample of children (n = 199 that was collected in New Orleans, Louisiana, in 2010. This dataset was linked to food environment data to assess the impact of neighborhood food access as well as household and parent factors on children’s diets. We observed a negligible impact of the neighborhood food environment on children’s diets, except with respect to fast food, with children who had access to fast food within 500 m around their home significantly less likely (OR = 0.35, 95% CI: 0.1, 0.8 to consume vegetables. Key parental and household factors did play a role in diet, including receipt of public assistance and cooking meals at home. Children receiving public assistance were 2.5 times (95% CI: 1.1, 5.4 more likely to consume fruit more than twice per day compared with children not receiving public assistance. Children whose family cooked dinner at home more than 5 times per week had significantly more consumption of fruit (64% vs. 58% and vegetables (55% vs. 39%, but less soda (27% vs. 43%. Findings highlight the need for future research that focuses on the dynamic and complex relationships between built and social factors in the communities and homes of children that impact their diet in order to develop multilevel prevention approaches that address childhood obesity.

Detrital shadows: estuarine food web connectivity depends on fluvial influence and consumer feeding mode.

Howe, Emily; Simenstad, Charles A; Ogston, Andrea

2017-10-01

We measured the influence of landscape setting on estuarine food web connectivity in five macrotidal Pacific Northwest estuaries across a gradient of freshwater influence. We used stable isotopes (δ 13 C, δ 15 N, δ 34 S) in combination with a Bayesian mixing model to trace primary producer contributions to suspension- and deposit-feeding bivalve consumers (Mytilus trossulus and Macoma nasuta) transplanted into three estuarine vegetation zones: emergent marsh, mudflat, and eelgrass. Eelgrass includes both Japanese eelgrass (Zostera japonica) and native eelgrass (Zostera marina). Fluvial discharge and consumer feeding mode strongly influenced the strength and spatial scale of observed food web linkages, while season played a secondary role. Mussels displayed strong cross-ecosystem connectivity in all estuaries, with decreasing marine influence in the more fluvial estuaries. Mussel diets indicated homogenization of detrital sources within the water column of each estuary. In contrast, the diets of benthic deposit-feeding clams indicated stronger compartmentalization in food web connectivity, especially in the largest river delta where clam diets were trophically disconnected from marsh sources of detritus. This suggests detritus deposition is patchy across space, and less homogenous than the suspended detritus pool. In addition to fluvial setting, other estuary-specific environmental drivers, such as marsh area or particle transport speed, influenced the degree of food web linkages across space and time, often accounting for unexpected patterns in food web connectivity. Transformations of the estuarine landscape that alter river hydrology or availability of detritus sources can thus potentially disrupt natural food web connectivity at the landscape scale, especially for sedentary organisms, which cannot track their food sources through space. © 2017 by the Ecological Society of America.

Theoretical difference between impact factor and influence factor

Full Text Available Bibliometric constructions of "knowledge maps" and "cognitive structures of science" do not differentiate between impact and influence factors. The difference can be constructedaccording to different meaning and interpretation of the terms reference and citation. Reference is "acknowledgment which one author gives to another", whereas citation is "acknowledgment which one document receives from another". Development of Information Science according to period and subject area is analyzed on the corpus of citation literature retrieved from doctoral dissertations in Information Science from 1978 to 2007 at Croatian universities. The research aim is to indicate the difference between document impact factor and author's influence factor (i.e. reference ability to produce effects on actions, behavior, and opinions of authors of doctoral theses. The influence factor serves to distinguish the key role of cited authors in time and according to the duration of the influence (the average age for cited papers of dominant authors in different periods is between eight and ten years. The difference between linear and interactive communication seems vital for the interpretation of cited half-life, i.e. the attitude of one science community towards used information resources and cognitive heritage. The analyzed corpus of 22,210 citations can be divided into three communication phases according to influence factor criteria: in the phase of dialogue and interactive communication 25% of bibliographic units are cited in the first four years; in the second phase another 25% of units are cited from the fifth to the ninth year; after ten years, in the dominant linear communication phase, approximately 30% of units are cited.

Time orientation can influence health-related behaviors, including food consumption. The aim of the present work was to study the influence of time orientation on food choice, using cookie labels as case study. A choice-conjoint task was designed using labels differing in type of cookie (chocolate chips vs. granola), front-of-pack nutrition information (nutritional warnings vs. Facts Up Front system) and nutritional claim (no claim vs. "0% cholesterol. 0% trans fat"). An online study was conducted, in which 155 participants evaluated 8 pairs of cookie labels and selected the one they would buy if they were in the supermarket. Then, they were asked to complete a consideration of future consequences scale (CFC) adapted to eating habits, as well as a questionnaire about socio-demographic characteristics. Time orientation influenced participants' choices of cookies labels; particularly the importance attached to type of cookie. Participants with greater consideration of future consequences preferred the granola cookies, associated with health, while those who prioritized immediate consequences preferred chocolate chip cookies. In addition, nutritional warnings discouraged choice regardless of participants' time orientation. Results from the present work provide additional evidence of the influence of time preferences on food choices and suggest that strategies to stimulate and generate a more future-oriented perspective on eating habits could contribute to more healthful food choices.

One way to increase choice of healthy over unhealthy behaviors is to increase the cost of less healthy alternatives or reduce the cost of healthier alternatives. The influence of price on purchases of healthy and unhealthy foods was evaluated in two laboratory experiments. In Experiment 1, thirty-two 10- to 12-year-old youth were given $5.00 and allowed to purchase multiple portions of a healthy food (fruit or vegetable) and a less healthy food (higher-fat snack). The price of one type of food varied from $0.50 to $2.50, while the price of the other type was held at $1.00. Increasing the price of a type of food reduced purchases of that type of food, but did not lead to substitution with the alternative type of food. In Experiment 2, twenty 10- to 14-year-old youth were given $1.00, $3.00, and $5.00 to purchase healthy and unhealthy foods. The price of each food was raised and lowered by 25% and 50%. Raising the price of healthy or unhealthy foods resulted in decreased purchases of those foods, and income available interacted with price to predict the pattern of substitution of alternative foods. These results show the potential for controlled laboratory studies of price and food purchases, and show that the substitution of healthier for unhealthy food is related to available money.

Whole grain consumption is associated with reduced risk of chronic disease. One-fifth of UK adults and children do not consume any whole grains, and adolescents have low consumption rates. Factors affecting whole grain intake among adolescents are not well understood. This study examined the socio-economic, environmental, lifestyle and psychological factors likely to influence consumption and explored whether outcomes aligned with behavioural predictors proposed in the Reasoned Action Approach. Five focus groups explored young people's attitudes towards, knowledge and consumption of wholegrain foods, as well as barriers to, and facilitators of, consumption. Participants were male and female adolescents (n = 50) aged 11-16 years from mixed socioeconomic backgrounds and ethnicities, recruited through schools in the city of Leeds, UK. Focus groups were analysed using thematic analysis. Most participants had tried wholegrain food products, with cereal products being the most popular. Many recognised whole grain health benefits related to digestive health but not those related to heart disease or cancers. Several barriers to eating whole grains were identified including: difficulties in identifying wholegrain products and their health benefits; taste and visual appeal; and poor availability outside the home. Suggested facilitators of consumption were advertisements and educational campaigns, followed by improved sensory appeal, increased availability and choice, and tailoring products for young people. All constructs of the Theory of Reasoned Action were identifiable in the data, suggesting that the factors influencing whole grain intake in adolescents are well captured by this model. Study outcomes may inform research and health promotion to increase whole grain intake in this age group. Copyright © 2016 Elsevier Ltd. All rights reserved.

Food-borne yeasts, excluding yeasts used as starter cultures, are commonly considered as food spoilage microorganisms. However, the incidence of non-C. albicans Candida (NCAC) infections has increased considerably over the past two decades. Although 15 Candida species are frequently identified as pathogens, a threat to human from food-borne Candida is poorly recognized. In the present study food-borne NCAC were characterized for the virulence factors, known to be associated with yeast pathogenicity. All food-borne strains in planktonic forms and 89% in biofilm structures represented biotypes established for C. albicans, and 61% demonstrated hemolytic activity. 56-94% of food-borne isolates formed biofilms on glass and biomaterials at a level comparable to clinical C. albicans. Nine out of eighteen tested food-borne NCAC strains (C. krusei, C. lusitaniae, C. famata, C. colliculosa, C. parapsilosis, C. tropicalis) showed similarity to clinical C. albicans in terms of their biotypes and the tested virulence factors, allocating them in a group of risk of potential pathogens. However, their capacity to grow at 37 °C seems to be the preliminary criterion in the study of potential virulence of food-borne yeasts. Copyright © 2018 Elsevier B.V. All rights reserved.

Hunger is associated with food insecurity at the household level and is considered as a global public health problem with long term adverse consequences on children's health. This study aims to determine the factors associated with child hunger from a nationally representative sample in Bangladesh among food insecure households. Data was derived from the Food Security and Nutritional Surveillance Project; 14,712 children aged 6-59 months belonging to food insecure households contributed to the analysis. Information on food security at the household level was collected for 30 days preceding the survey. Descriptive statistics served to illustrate the variables studied and multiple logistic regression analysis was conducted to identify the significant risk factors for child hunger. Overall 10% of the children were found to be hungry. After adjusting for seasonality, residence type and education level of household head, the variables - female headed households [OR: 1.87 (1.43-2.45); p hunger. Out of the potential risk factors examined, our study found significant and independent association of five variables with child hunger: sex of the household head, household food insecurity status, educational status of household women and asset index. Despite all sampled household being food insecure, degree of household food insecurity status appeared to be the strongest predictor of child hunger.

The increase number of active users of social media, especially Facebook, stimulates viral advertising behaviour among them, thus attracting e-marketers to focus on viral advertising in promoting their products. In global market, use of Facebook platform indicated that food services/restaurant of food industry is ranked number 11 with 18.8% users’ response rate within the platform. This development calls for e-marketers in Malaysia to use Facebook as their viral advertising channel. Attitudinal factors affecting the viral advertising pass-on behaviour (VAPB) especially among members of social media is of interest to many researchers. The typical attitudinal factors used were attitude toward social media (ATSM), attitude toward advertising in social media (AASM) and attitude toward advertising in general (AAIG). Attitude toward advertised brand (ATAB) is important in fast food industry because users of social media tend to share their experience about tastes and features of the food. However, ATAB is less emphasized in the conceptual model between attitudinal factors and VAPB. These four factors of consumer attitude served as independent variables in the conceptual model of this study and their effect on viral advertising pass-on behaviour among members of Domino's Pizza Malaysia Facebook page was examined. Online survey using a set of questionnaire which was sent to the members of this group via private message was employed. A total of 254 sets of usable questionnaires were collected from the respondents. All the attitudinal factors, except for AASM, were found to have positive and significant effect on VAPB. AAIG exerted the strongest effect on VAPB. Therefore, e-marketers should emphasize on developing a favourable attitude toward advertising in general among members of a social media to get them involve in viral advertising. In addition, instilling a favourable attitude towards advertised brand is also vital as it influences the members to viral the brand

Full Text Available Motivation is one of the most important factors influencing workers' productivity. An increase in workers' motivation could add more value to organizations' structure and influence the profitability, significantly. In this paper, we study different factors on demotivating workers using questionnaire consist of various questions. The questionnaire is distributed among some employees who work for rubber production units located in Esfahan, Iran. The results of this survey indicate that discrimination on annual job compensation, entrusting responsibilities and unpleasant relationship with family partner are some of the most important factors influencing employees' motivation. While financial factors play important role on increasing employees' motivation, non-financial factors are considered more important.

Factors Influencing the Phenotypic Characterization of the Oral Marker, PROP

Directory of Open Access Journals (Sweden)

Beverly J. Tepper

2017-11-01

Full Text Available In the last several decades, the genetic ability to taste the bitter compound, 6-n-propyltiouracil (PROP has attracted considerable attention as a model for understanding individual differences in taste perception, and as an oral marker for food preferences and eating behavior that ultimately impacts nutritional status and health. However, some studies do not support this role. This review describes common factors that can influence the characterization of this phenotype including: (1 changes in taste sensitivity with increasing age; (2 gender differences in taste perception; and (3 effects of smoking and obesity. We suggest that attention to these factors during PROP screening could strengthen the associations between this phenotype and a variety of health outcomes ranging from variation in body composition to oral health and cancer risk.

Sensory influences on food intake control: moving beyond palatability.

Science.gov (United States)

McCrickerd, K; Forde, C G

2016-01-01

The sensory experience of eating is an important determinant of food intake control, often attributed to the positive hedonic response associated with certain sensory cues. However, palatability is just one aspect of the sensory experience. Sensory cues based on a food's sight, smell, taste and texture are operational before, during and after an eating event. The focus of this review is to look beyond palatability and highlight recent advances in our understanding of how certain sensory characteristics can be used to promote better energy intake control. We consider the role of visual and odour cues in identifying food in the near environment, guiding food choice and memory for eating, and highlight the ways in which tastes and textures influence meal size and the development of satiety after consumption. Considering sensory characteristics as a functional feature of the foods and beverages we consume provides the opportunity for research to identify how sensory enhancements might be combined with energy reduction in otherwise palatable foods to optimize short-term energy intake regulation in the current food environment. Moving forward, the challenge for sensory nutritional science will be to assess the longer-term impact of these principles on weight management. © 2015 World Obesity.

2015-10-16

An increased consumption of energy-dense, nutrient-poor food and beverages as a result of a changing obesogenic environment contributes substantially to the increasing prevalence of childhood overweight and obesity. This paper reviews the nature and extent of food industry influences which expose children to commercial influences and thus might affect unhealthy dietary behaviour and finally contributes to obesity. A systematic search of nine electronic databases (including PubMed, PsycINFO, EconLit) and reference lists of original studies and reviews using key search terms identified 1900 articles. Of these only thirty-six articles met the inclusion and quality criteria. A narrative synthesis of the reviewed studies revealed six key obesogenic environments by which the food industry possibly influences obesity-related dietary behaviours in young children. These were schools, retailers, mass media "television", mass media "internet", home and promotional campaigns. Identifying these obesogenic environments is critical for monitoring and controlling the food industry, the development of effective environmental-level interventions to prevent childhood overweight and obesity and to identify knowledge gaps to be addressed in future research to support informed decisions of policy makers.

Wissel, Björn; Fry, Brian

2005-08-01

The Breton Sound estuary in southern Louisiana receives large amounts of Mississippi River water via a controlled diversion structure at the upstream end of the estuary. We used stable isotopes to trace spatial and seasonal responses of the downstream food web to winter and spring introductions of river water. Analysis of delta13C, delta15N, and delta34S in the common local consumers such as grass shrimp (Palaemonetes sp.), barnacles (Balanus sp.), and small plankton-feeding fish (bay anchovies, Anchoa mitchilli) showed that the diversion was associated with two of the five major source regimes that were supporting food webs: a river regime near the diversion and a river-influenced productive marsh regime farther away from the diversion. Mixing models identified a third river-influenced source regime at the marine end of the estuary where major natural discharge from the Bird's Foot Delta wraps around into estuarine waters. The remaining two source regimes represented typical estuarine conditions: local freshwater sources especially from precipitation and a brackish source regime representing higher salinity marine influences. Overall, the Mississippi River diversion accounted for 75% of food web support in the upper estuary and 25% in the middle estuary, with influence strongest along known flow pathways and closest to the diversion. Isotopes also traced seasonal changes in river contributions, and indicated increased plant community productivity along the major flow path of diversion water. In the Breton Sound estuary, bottom-up forcing of food webs is strongly linked to river introductions and discharge, occurring in spatial and temporal patterns predictable from known river input regimes and known hydrologic circulation patterns.

US consumers spend more than $20 billion/year on over-the-counter (OTC) drugs. Although generic and brand name OTC drugs share the same active ingredients and undergo the same rigorous Food and Drug Administration approval process, brand name formulations continue to lead the OTC drug market with a higher market share. There is a limited amount of publicly available information regarding consumer perceptions and awareness about generic and brand name OTC drugs. The main objective of this research was to understand what factors influence US consumers to purchase generic versus brand name OTC drugs. The researchers used a 20-question, self-administered, multiple-choice survey to collect data on the factors influencing consumers' preferences for generic versus brand name OTC drugs. Results revealed that the single most influential factor for participants when purchasing OTC drugs was lower cost. Although economic factors play an important role in influencing consumers to choose generic formulations, a variety of other factors including advertisements, duration of the OTC effectiveness, severity of sickness, preferable form of OTC medication, safety of the OTC, relief of multiple symptoms, and preferred company will persuade others to pay more for brand name drugs. Ultimately, increased awareness and use of generic OTC drugs may result in substantial cost savings for consumers.

Individual and environmental influences on adolescent eating behaviors.

Story, Mary; Neumark-Sztainer, Dianne; French, Simone

2002-03-01

Food choices of adolescents are not consistent with the Dietary Guidelines for Americans. Food intakes tend to be low in fruits, vegetables, and calcium-rich foods and high in fat. Skipping meals is also a concern among adolescents, especially girls. Factors influencing eating behaviors of adolescents need to be better understood to develop effective nutrition interventions to change eating behaviors. This article presents a conceptual model based on social cognitive theory and an ecological perspective for understanding factors that influence adolescent eating behaviors and food choices. In this model, adolescent eating behavior is conceptualized as a function of individual and environmental influences. Four levels of influence are described: individual or intrapersonal influences (eg, psychosocial, biological); social environmental or interpersonal (eg, family and peers); physical environmental or community settings (eg, schools, fast food outlets, convenience stores); and macrosystem or societal (eg, mass media, marketing and advertising, social and cultural norms).

Obesity has increased since the early 1980s, and despite numerous attempts, effective strategies to counter this worldwide epidemic are lacking. Food preferences are established early in life and are difficult to change later. There is therefore a need to identify factors that influence...... the development of food preferences. Our aim was therefore, to investigate cross-sectional and prospective associations between TV viewing habits and food preferences and habits, respectively. We hypothesized that more TV viewing was associated with less healthy concomitant and future food preferences and food...

Food as a way to convey masculinities: How conformity to hegemonic masculinity norms influences men's and women's food consumption.

Campos, Lúcia; Bernardes, Sónia; Godinho, Cristina

2018-05-01

This study investigated how conformity to hegemonic masculinity norms affects men's and women's food consumption and whether such influence was contextually modulated. A total of 519 individuals (65% women; M = 44 years old) participated in a 2 (gender salience: low vs high) × 2 (participants' sex: male vs female) quasi-experimental between-subjects design, completing the Conformity to Masculinity Norms Inventory (Portuguese version) and reporting their past week's food consumption. Gender salience moderated the relation between men's conformity to masculinity norms and food consumption; sex-related differences in food consumption were partially mediated by conformity to masculinity norms. Implications for food consumption interventions are discussed.

2010-06-01

Globally, foodborne illness affects an estimated 30% of individuals annually. Meals prepared outside of the home are a risk factor for acquiring foodborne illness and have been implicated in up to 70% of traced outbreaks. The Centers for Disease Control and Prevention has called on food safety communicators to design new methods and messages aimed at increasing food safety risk-reduction practices from farm to fork. Food safety infosheets, a novel communication tool designed to appeal to food handlers and compel behavior change, were evaluated. Food safety infosheets were provided weekly to food handlers in working food service operations for 7 weeks. It was hypothesized that through the posting of food safety infosheets in highly visible locations, such as kitchen work areas and hand washing stations, that safe food handling behaviors of food service staff could be positively influenced. Using video observation, food handlers (n = 47) in eight food service operations were observed for a total of 348 h (pre- and postintervention combined). After the food safety infosheets were introduced, food handlers demonstrated a significant increase (6.7%, P < 0.05, 95% confidence interval) in mean hand washing attempts, and a significant reduction in indirect cross-contamination events (19.6%, P < 0.05, 95% confidence interval). Results of the research demonstrate that posting food safety infosheets is an effective intervention tool that positively influences the food safety behaviors of food handlers.

The study comprises a systematic and quantitative evaluation of potential intrinsic and extrinsic factors that impact vitamin C degradation in a real food matrix. The supernatant of centrifuged apple purée was fortified in vitamin C, and degradation was followed without stirring. Model discrimination indicated better fit for the zero order model than the first order model which was hence chosen for determination of rate constants. pH influenced strongly vitamin C degradation in citrate-phosphate buffer but not in the apple purée serum. To get an idea of the impact of the food matrix, stability in apple purée serum was compared with that in carrot purée. In the latter, stability was slightly higher. Vitamin C degradation rates were not influenced by its initial concentration. The temperature effect was only marked in the temperature range 40-60°C. In the range 60-80°C, filling height of tubes had the greatest impact. Copyright © 2016 Elsevier Ltd. All rights reserved.

The purpose of this study was to identify the food habits of pregnant adolescents and their perception about which, of her cultural concepts, have higher influence. 54 subjects between 12 and 19 years old from Guadalajara City were included and socioeconomic, dietetic data, as food frequency consumption and cultural concepts about feeding were also explored. Chi square was used for identifying association between variables. The fat intake was lower in late vs. Early and middle stage of adolescence (57 vs. 71 g/d, p = 0.05). The iron, calcium and zinc intake was also deficient in the early/middle stage; meanwhile, the folic acid consumption was very low in the late stage of adolescence. Corn tortillas were the most consumed cereal and food (93-96%); junk food and sodas (62 and 55%) prevailed in the early/middle stage. About local costumes, "tacos", "pozole" and burgers were the most referred (74.1%). They also mentioned that fat (36.7%), junk food (30%), chili (26.7%), sodas (23.3%), processed meals (26.7%) and salt (10%) were harmful. They also believed that vegetables (77%), fruits (60 %), milk (21%), broths (17%), and meat (12.5%) were beneficial; and, 96% considered that chicken and bean broths were nutritious (myth). There were some prohibited foods (taboos) during pregnancy: chili (48%), junk food (20%), and salt (16%). Prejudices were more common among later adolescents (60.9%) (p = 0.03). The erratic food habits and the conceptual confusion of these adolescents cause a low intake of nutrients and place them in a nutritional risk.

2018-02-15

This study focuses on understanding factors that influence food agency in the Spanish population, specifically with regard to cooking habits, knowledge, and determinants and their possible relationship with body weight. A cross-sectional telephone survey was conducted. Individuals were asked about their cooking responsibilities, how they learned to cook, factors that affect their food choices, and their preferred cooking techniques. Anthropometric data were also recorded. Participants were randomly selected, and we finally had 2026 respondents aged ≥18 years (60% women, 40% men). A total of 90.5% of participants stated that they had cooking skills. Women were mainly responsible for cooking tasks ( p < 0.05) at all ages. A significantly higher proportion of people under 50 years self-reported that they were "able to cook" in comparison with groups over 50 years. Regardless of age, most participants learned to cook either by practice (43.3%) or from a family member (42.2%). Men tended to be more autodidactic, whereas women reported learning from family. No relation was found between weight status and the evaluated factors investigated. In conclusion, women bear the responsibility for the entire cooking process in families, indicating a gender gap in the involvement of men in cooking responsibilities and competence. More research is needed to assess the influence of cooking knowledge on obesity prevention.

Influence of food companies' brand mascots and entertainment companies' cartoon media characters on children's diet and health: a systematic review and research needs

Kraak, V I; Story, M

2015-01-01

Reducing the extent and persuasive power of marketing unhealthy foods to children worldwide are important obesity prevention goals. Research is limited to understand how brand mascots and cartoon media characters influence children's diet. We conducted a systematic review of five electronic databases (2000–2014) to identify experimental studies that measured how food companies' mascots and entertainment companies' media characters influence up to 12 diet-related cognitive, behavioural and health outcomes for children under 12 years. Eleven studies met the inclusion criteria. Studies used 21 unique popular media characters, but no brand mascots. Results suggest that cartoon media character branding can positively increase children's fruit or vegetable intake compared with no character branding. However, familiar media character branding is a more powerful influence on children's food preferences, choices and intake, especially for energy-dense and nutrient-poor foods (e.g. cookies, candy or chocolate) compared with fruits or vegetables. Future research should use a theoretically grounded conceptual model and larger and more diverse samples across settings to produce stronger findings for mediating and moderating factors. Future research can be used to inform the deliberations of policymakers, practitioners and advocates regarding how media character marketing should be used to support healthy food environments for children.

Full Text Available Introduction/Objective. As a risk factor for chronic diseases, metabolic syndrome (MS is increasing at an alarming rate. The prevalence of MS varies according to lifestyle and occupation in different populations. The present study aimed to determine the prevalence of MS and its components in food suppliers. Methods. A total of 112 food suppliers were randomly selected from all around the city. Data collection tools included demographic, physical activity, and food frequency questionnaires. Body composition was measured using Bio-Electrical Body Analyzer. A sample of 5 ml of fasting blood was taken from participants to assess lipid profile, blood sugar, insulin, and liver enzymes. The data were analyzed using χ2, Kolmogorov–Smirnov and ANOVA tests. Results. Participants’ mean BMI was 27.1 ± 3.9 kg/m2, 43.6% were overweight, and 26.4% were obese. Consumption of vegetables was less and of meats more than recommended amounts. The prevalence of MS was 45.5% (51 people, which increased with aging (p = 0.02. Among factors causing MS, the most common one was waist-to-hip ratio (WHR > 0.09 (72.7%, followed by high triglyceride and low HDL. Conclusion. In this study, the prevalence of MS among food suppliers was higher than the world average and than prevalence in other countries. WHR (or obesity was found to be the most important risk factor for MS. To reduce the risk of MS, changing dietary consumption habits and increased physical activity are recommended to persons with high risk and sedentary occupations.

Promoting Healthy Menu Choices in Fast Food Restaurant Advertising: Influence of Perceived Brand Healthiness, Brand Commitment, and Health Consciousness.

Science.gov (United States)

Choi, Hojoon; Reid, Leonard N

2018-01-01

Fast food restaurants have increasingly turned to healthier choices to counter criticisms of nutritionally poor menu offerings and to differentiate themselves from the competition. However, research has yet to specifically investigate how consumers respond to advertisements for these healthier foods. To address this knowledge gap, two experiments were conducted to examine how perceived brand healthiness, brand commitment, and health consciousness influence responses to nutrient-content claimed print advertisements for healthy foods. Findings indicate that consumer responsiveness varies across the three factors but is more positive for advertisements placed by perceivably healthy restaurant brands, and that brand commitment and health consciousness play significant roles in affecting how consumer respond to such advertising. Several theoretical and managerial implications of the findings are discussed.

Until now, the literatures on the effects of food parenting practices and parents' own dietary behavior on children's dietary behavior have largely been independent from one another. Integrating findings across these areas could provide insight on simultaneous and interacting influences on children's food intake. In this narrative review, we provide a conceptual model that bridges the gap between both literatures and consists of three main hypotheses. First, parental dietary behavior and food parenting practices are important interactive sources of influence on children's dietary behavior and Body Mass Index (BMI). Second, parental influences are importantly mediated by changes in the child's home food environment. Third, parenting context (i.e., parenting styles and differential parental treatment) moderates effects of food parenting practices, whereas child characteristics (i.e., temperament and appetitive traits) mainly moderate effects of the home food environment. Future studies testing (parts of) this conceptual model are needed to inform effective parent-child overweight preventive interventions. Copyright © 2015 Elsevier Ltd. All rights reserved.

Food-packaging interactions influencing quality and safety.

Science.gov (United States)

Hotchkiss, J H

1997-01-01

Interactions between foods and packaging can be detrimental to quality and/or safety. Changes in product flavour due to aroma sorption and the transfer of undesirable flavours from packaging to foods are important mechanisms of deterioration when foods are packaged in polymer-based materials. Careful consideration must be given to those factors affecting such interactions when selecting packaging materials in order to maximize product quality, safety, and shelf-life while minimizing undesirable changes. Product considerations include sensitivity to flavour and related deteriorations, colour changes, vitamin loss, microbial activity, and amount of flavour available. Storage considerations include temperature, time, and processing method. Polymer considerations include type of polymer and processing method, volume or mass of polymer to product ratio, and whether the interaction is Fickian or non-Fickian. Methodology to determine the extent of such interactions must be developed. Direct interactions between food and packaging are not necessarily detrimental. The same principles governing undesirable interactions can be used to affect desirable outcomes. Examples include films which directly intercept or absorb oxygen, inhibit microorganisms, remove undesirable flavours by sorption, or indicate safety and product shelf-life.

Environmental conditions influence meal size in adults and children. Intake of sweet drinks could contribute significantly to energy intake and potentially affect body weight, particularly in young individuals. The objectives of the present study were to measure the lunch intake of food and drinks under controlled laboratory settings in teenagers and to compare the influence of different meal conditions. Normal-weight adolescents (fourteen males and fifteen females) participated in four standardised lunches, scheduled 1 week apart. The same popular items (meat dish, dessert, water, juice, soda) were served at all meals. Ad libitum intake was measured under four conditions: subjects ate alone; in groups; alone while viewing television; alone while listening to music. Visual analogue scales were used to assess pre- and post-meal hunger and thirst and meal palatability. Energy, solid food and fluid intake was different (significantly lower) only in the 'eating in group' condition, in spite of identical intensity of pre-meal hunger. More soda was consumed when participants were watching television, and more water was consumed while listening to music. Across all conditions, more soda than water was consumed. Post-meal ratings of hunger, thirst and palatability did not differ between conditions. We concluded that, in teenagers, a 'social inhibition' effect appears rather than the 'social facilitation' previously reported in adults. Although teenagers do not respond to the presence of television or another 'distractor' such as music by eating more, they do ingest more soda when the television is on. The social significance of meals, conditioned responses and habituation to 'distractors' may be different between adolescents and adults.

Continuous monitoring of fluid changes using bioimpedance spectroscopy (BIS) during hemodialysis could help to predict hypotensive complications and extend the patient's life. Food and beverage consumption during the treatment may influence the measurements and the calculated fluid removal. In the present article the change observed in whole body and segmental (knee-to-knee, abdomen) BIS measurements following a sequence similar to the one of dialysis treatment (lying down, sitting and eating, lying down) on healthy subjects is presented. The measurements have been performed using a commercial bioimpedance device with a frequency range of 5 kHz to 1 MHz. Knee-to-knee measurements seem to be less sensitive to these influences, compared to the standard whole body and the alternative abdomen BIS measurements. The results indicate that the individual influence of both body posture and food and beverage consumption may be superposed when combined.

Avoidable food waste is produced in the food service sector, with significant ecological and economical impacts. In order to understand and explain better the complex issue of food waste a qualitative study was conducted on the reasons for its generation in restaurants and catering businesses. Research data were collected during three participatory workshops for personnel from three different catering sector companies in Finland. Based on synthesized qualitative content analysis, eight elements influencing production and reduction of food waste were identified. Results revealed the diversity of managing food waste in the food service sector and how a holistic approach is required to prevent and reduce it. It is crucial to understand that food waste is manageable and should be an integral component of the management system. The model of eight factors provides a framework for recognition and management of food waste in the food service sector. Copyright © 2016 Elsevier Ltd. All rights reserved.

To investigate: (i) the percentage of the New Zealand (NZ) population reporting fast food/takeaway food and restaurant/café food per day; (ii) examine demographic factors associated with their use; (iii) quantify their contribution to energy intake; and (iv) describe the specific types of foods reported from both sources. Twenty-four hour diet recalls from the cross-sectional 2008/09 NZ Adult Nutrition Survey were used to identify fast-food and restaurant-food consumers. NZ households. Adults aged 15 years and older (n 4721). Overall 28 % reported consuming at least one fast food and 14 % a restaurant food within the 24 h diet recall. Fast-food consumption was not associated with level of education or an area-based measure of socio-economic status, but a higher education was positively associated with restaurant-food consumption. Individual factors such as ethnicity, household size, age, sex and marital status were found to be important influences on the use of fast food and restaurant food. Fast-food consumption was more prevalent among participants living in urban areas, young adults (19-30 years) and Māori compared with NZ European and Others. The most frequently reported fast foods were bread-based dishes, potatoes (including fries) and non-alcoholic beverages. Given the high reported consumption of fast food by young adults, health promotion initiatives both to improve the nutritional quality of fast-food menus and to encourage healthier food choices would likely make a large impact on the overall diet quality of this group.

STUDY OF FACTORS AFFECTING DEVELOPMENT OF FOOD AROMATIZATION

Directory of Open Access Journals (Sweden)

Н.Ye. Dubova

2017-10-01

Full Text Available The specific understanding of food philosophy according to the facts of development of cooking technologies and growth rate of food range is given. As it has been proven by historical stages of production of flavorings, aroma is one of the important organoleptic ingredients for food developers. A review of food production based on development of nanotechnologies, as well as promising and cautioning publications on nanotechnologies in the food sector is presented. On the basis of the literary analysis, the future impact of nanotechnologies on the evolution of the aromatization process of food products is predicted. It has been determined that the peculiarity of the development mentioned above lies in the use of plant enzymes and / or flavor precursors in the nanoscale range. The example of enzymatic breakdown of polyunsaturated fatty acids of plant cell membranes as one of the ways of creating fresh flavor of many fruits, namely C6-C9 aldehydes and alcohols, is considered. It is noted that green fresh aromatic ingredients are needed to improve the organoleptic profile of foods from heat-treated vegetables, melons and gourds. The following factors affecting the development of food aromatization are defined: the decreased differentiation of principles of healthy nutrition and fast food, repetition of natural processes of aroma formation, application of wild green leafy vegetables, and evolution of medical nutrition. The information on food aromatization by packing with autonomous mixing and their approximate assortment is given. The innovations in food aromatization are aimed at quality nutrition, time saving, recreation and entertainment, meeting specific needs (vegetarian dishes, restrictive diets.

To study main risk factors that cause foodborne diseases in food catering business. Data from references and investigations conducted in food catering units were used to establish models which based on @Risk 4.5 with Monte Carlo method referring to food handling practice model (FHPM) to make risk assessment on factors of food contamination in food catering units. The Beta-Poisson models on dose-response relationship to Salmonella (developed by WHO/FAO and United States Department of Agriculture) and Vibrio parahaemolyticus (developed by US FDA) were used in this article to analyze the dose-response relationship of pathogens. The average probability of food poisoning by consuming Salmonella contaminated cooked meat under refrigeration was 1.96 × 10(-4) which was 1/2800 of the food under non-refrigeration (the average probability of food poisoning was 0.35 at room temperature 25°C). The average probability by consuming 6 hours stored meat under room temperature was 0.11 which was 16 times of 2 hours storage (6.79 × 10(-3)). The average probability by consuming contaminated meat without fully cooking was 1.71 × 10(-4) which was 100 times of consuming fully cooked meat (1.88 × 10(-6)). The probability growth of food poisoning by consuming Vibrio parahaemolyticus contaminated fresh seafood was proportional with contamination level and prevalence. The primary contamination level, storage temperature and time, cooking process and cross contamination are important factors of catering food safety.

Quantifying and analysing food waste generated by Indonesian undergraduate students

Science.gov (United States)

Mandasari, P.

2018-03-01

Despite the fact that environmental consequences derived from food waste have been widely known, studies on the amount of food waste and its influencing factors have relatively been paid little attention. Addressing this shortage, this paper aimed to quantify monthly avoidable food waste generated by Indonesian undergraduate students and analyse factors influencing the occurrence of avoidable food waste. Based on data from 106 undergraduate students, descriptive statistics and logistic regression were applied in this study. The results indicated that 4,987.5 g of food waste was generated in a month (equal to 59,850 g yearly); or 47.05 g per person monthly (equal to 564.62 g per person per a year). Meanwhile, eating out frequency and gender were found to be significant predictors of food waste occurrence.

Factors modulating social influence on spatial choice in rats.

Bisbing, Teagan A; Saxon, Marie; Sayde, Justin M; Brown, Michael F

2015-07-01

Three experiments examined the conditions under which the spatial choices of rats searching for food are influenced by the choices made by other rats. Model rats learned a consistent set of baited locations in a 5 × 5 matrix of locations, some of which contained food. In Experiment 1, subject rats could determine the baited locations after choosing 1 location because all of the baited locations were on the same side of the matrix during each trial (the baited side varied over trials). Under these conditions, the social cues provided by the model rats had little or no effect on the choices made by the subject rats. The lack of social influence on choices occurred despite a simultaneous social influence on rats' location in the testing arena (Experiment 2). When the outcome of the subject rats' own choices provided no information about the positions of other baited locations, on the other hand, social cues strongly controlled spatial choices (Experiment 3). These results indicate that social information about the location of food influences spatial choices only when those cues provide valid information that is not redundant with the information provided by other cues. This suggests that social information is learned about, processed, and controls behavior via the same mechanisms as other kinds of stimuli. (c) 2015 APA, all rights reserved).

To investigate influences on shopping and eating behavior of Hmong adults living in St. Paul/Minneapolis, Minnesota. Conducted a mapping project, food surveys, food frequency questionnaire (FFQ), and focus groups (n = 11). Subjects were assigned to three groups. The B-TL(1) group was made up of subjects who were born in Thailand/Laos and had lived in the US 5 years (n = 20). The B-US group was made up of subjects who were born and/or raised in the US (n = 30). Using Geographical Informational Systems software, 15 grocery stores were mapped and surveyed. Food prices were compared with the consumer price index (CPI). The FFQ assessed food consumption patterns. Focus group transcripts were evaluated for themes and coded. Degree of acculturation was assessed by adapting a previously developed instrument. The population is concentrated in St. Paul, coinciding with store density. Limited foods had CPIs and some CPIs were outdated. B-US had significantly higher levels of dietary acculturation than B-TL(2) and B-TL(1), with B-TL(2) also having a higher dietary acculturation level compared with B-TL(1). Acculturation of the Hmong into the American food system, determinants of store type, and Hmong food's having a mainstream factor were identified themes. B-US and B-TL(2) shopped at American stores more than did B-TL(1) because of convenience, one-stop shopping, and increased English fluency. Hmong foods have entered the American food system and are sold at Asian and American stores.

Commercial food marketing has considerably shaped consumer food choice behaviour. Meanwhile, public health campaigns for healthier eating have had limited impact to date. Social marketing suggests that successful commercial food marketing campaigns can provide useful lessons for public sector activities. The aim of the present study was to empirically identify food marketing success factors that, using the social marketing approach, could help improve public health campaigns to promote healthy eating. In this case-study analysis, 27 recent and successful commercial food and beverage marketing cases were purposively sampled from different European countries. The cases involved different consumer target groups, product categories, company sizes and marketing techniques. The analysis focused on cases of relatively healthy food types, and nutrition and health-related aspects in the communication related to the food. Visual as well as written material was gathered, complemented by semi-structured interviews with 12 food market trend experts and 19 representatives of food companies and advertising agencies. Success factors were identified by a group of experts who reached consensus through discussion structured by a card sorting method. Six clusters of success factors emerged from the analysis and were labelled as "data and knowledge", "emotions", "endorsement", "media", "community" and "why and how". Each cluster subsumes two or three success factors and is illustrated by examples. In total, 16 factors were identified. It is argued that the factors "nutritional evidence", "trend awareness", "vertical endorsement", "simple naturalness" and "common values" are of particular importance in the communication of health with regard to food. The present study identified critical factors for the success of commercial food marketing campaigns related to the issue of nutrition and health, which are possibly transferable to the public health sector.

To examine if food group consumption varies by differences in socioeconomic, demographic, and lifestyle factors in young adults from a semirural setting in Louisiana. Cross-sectional. Young adults (n=1,266, 74% European American, 26% African American; 39% men, 61% women) aged 20 to 38 years, enrolled in the Bogalusa Heart Study. Food group consumption was assessed by a food frequency questionnaire. Socioeconomic (eg, income and education), demographic (eg, age, sex, and ethnicity), and lifestyle (eg, marital status and physical activity) information was obtained by a self-administered questionnaire and the subjects were stratified according to these groups. Analysis of covariance (adjusted for covariates) was used to detect differences in the mean servings of food groups consumed per day between the various socioeconomic, demographic, and lifestyle groups.

Lower birth weight, often found in infants from minority ethnic groups, may be partly because of the disproportionate representation of ethnic minority groups in low-income areas. To develop an intervention, to improve the nutritional intake of young women from populations at risk of low-birth-weight babies, which would be culturally sensitive and well received by the intended recipients, a community development approach was used to investigate factors that might influence food choice and the nutritional intake of girls and young women from ethnic minority groups. Focus group discussions were conducted across the UK, to explore factors that might affect the food choices of girls and young women of African and South Asian decent. The data was analysed using deductive content analysis (Qual. Soc. Res., 1, 2000, 1). Discussions were around the broad themes of buying and preparing food, eating food and dietary changes, and ideas for an intervention to improve diet. The focus group discussions indicated that all the communities took time, price, health and availability into consideration when making food purchases. The groups were also quite similar in their use of 'Western' foods which tended to be of the fast food variety. These foods were used when there was not enough time to prepare a 'traditional' meal. Many issues that affect the food choice of people who move to the UK are common within different ethnic groups. The idea of a practical intervention based on improving cooking skills was popular with all the groups.

Food Retailers and Obesity.

Science.gov (United States)

Stanton, Rosemary A

2015-03-01

We live in an 'obesogenic environment' where we are constantly bombarded with choices that encourage us to move less and eat more. Many factors influence our dietary choices, including the expert marketers who advise manufacturers on ways to encourage the population to buy more, especially profitable, palatable 'ultra-processed' foods. Supermarkets themselves have become skilled in manipulating buying behaviour, using their layout and specific product placement as well as advertising to maximise purchases of particular foods. Increasingly, supermarkets push their own 'house' brands. Those marketing fast foods also use persuasive tactics to attract customers, especially children who they entice with non-food items such as promotional or collectable toys. There is no mystery to the increase in obesity: our energy intake from foods and drinks has increased over the same period that energy output has decreased. Obesity has a range of relevant factors, but there is little doubt that marketing from supermarkets and fast food retailers has played a role.

Reducing the extent and persuasive power of marketing unhealthy foods to children worldwide are important obesity prevention goals. Research is limited to understand how brand mascots and cartoon media characters influence children's diet. We conducted a systematic review of five electronic databases (2000-2014) to identify experimental studies that measured how food companies' mascots and entertainment companies' media characters influence up to 12 diet-related cognitive, behavioural and health outcomes for children under 12 years. Eleven studies met the inclusion criteria. Studies used 21 unique popular media characters, but no brand mascots. Results suggest that cartoon media character branding can positively increase children's fruit or vegetable intake compared with no character branding. However, familiar media character branding is a more powerful influence on children's food preferences, choices and intake, especially for energy-dense and nutrient-poor foods (e.g. cookies, candy or chocolate) compared with fruits or vegetables. Future research should use a theoretically grounded conceptual model and larger and more diverse samples across settings to produce stronger findings for mediating and moderating factors. Future research can be used to inform the deliberations of policymakers, practitioners and advocates regarding how media character marketing should be used to support healthy food environments for children. © 2014 The Authors.

Full Text Available Abstract Background Hunger is associated with food insecurity at the household level and is considered as a global public health problem with long term adverse consequences on children’s health. This study aims to determine the factors associated with child hunger from a nationally representative sample in Bangladesh among food insecure households. Methods Data was derived from the Food Security and Nutritional Surveillance Project; 14,712 children aged 6–59 months belonging to food insecure households contributed to the analysis. Information on food security at the household level was collected for 30 days preceding the survey. Descriptive statistics served to illustrate the variables studied and multiple logistic regression analysis was conducted to identify the significant risk factors for child hunger. Results Overall 10% of the children were found to be hungry. After adjusting for seasonality, residence type and education level of household head, the variables - female headed households [OR: 1.87 (1.43–2.45; p < 0.001], severely food insecure households [OR: 10.5 (1.43–76.6; p < 0.05], households having women with no education [OR: 1.56 (1.27–1.92; p < 0.05], poorest asset quintile [OR: 1.50 (1.11–2.15; p < 0.05] and the amount of rice consumed per household per week [OR: 0.94 (0.92–0.96; p < 0.001] were found to be significantly and independently associated with child hunger. Conclusions Out of the potential risk factors examined, our study found significant and independent association of five variables with child hunger: sex of the household head, household food insecurity status, educational status of household women and asset index. Despite all sampled household being food insecure, degree of household food insecurity status appeared to be the strongest predictor of child hunger.

2009-06-01

This study aimed to understand parents' evaluations of the way they integrated work-family demands to manage food and eating. Employed, low/moderate-income, urban, U.S., Black, White, and Latino mothers (35) and fathers (34) participated in qualitative interviews exploring work and family conditions and spillover, food roles, and food-choice coping and family-adaptive strategies. Parents expressed a range of evaluations from overall satisfaction to overall dissatisfaction as well as dissatisfaction limited to work, family life, or daily schedule. Evaluation criteria differed by gender. Mothers evaluated satisfaction on their ability to balance work and family demands through flexible home and work conditions, while striving to provide healthy meals for their families. Fathers evaluated satisfaction on their ability to achieve schedule stability and participate in family meals, while meeting expectations to contribute to food preparation. Household, and especially work structural conditions, often served as sizeable barriers to parents fulfilling valued family food roles. These relationships highlight the critical need to consider the intersecting influences of gender and social structure as influences on adults' food choices and dietary intake and to address the challenges of work and family integration among low income employed parents as a way to promote family nutrition in a vulnerable population.

2016-08-01

Focus groups (n = 7) were conducted with Chinese students (n = 43) studying in the USA to determine how acculturation and environmental factors influence dietary behavior and body mass index (BMI). This study used mixed methodology, collecting both qualitative (focus groups) and quantitative (24-h dietary recalls, food adoption scores, degree of acculturation, and height and weight measures) data. Themes emerging from focus group discussions were: a) dietary and social acculturation, b) factors influencing food intake, c) cultural importance of food, and d) changes in weight and BMI status. Environmental, behavioral, and cultural factors appear to have impacted the eating behaviors of the students. Because of the nature of the study, self-reported heights and weights were used to calculate BMI while living in China and actual heights and weights were taken for each student at the focus group to calculate current BMI after living in the USA. The majority of Chinese students (69% males; 85% females) experienced weight gain, resulting in an increased BMI based on weight/height data and as reported in focus group discussions. As a result, if students continue to gain weight, they may be at higher risk of developing chronic diseases in the future. Further, implemented dietary change may be transferred to other family members if students return to China. Results suggest that nutrition education should be provided to incoming foreign students during their orientation. Copyright © 2016 Elsevier Ltd. All rights reserved.

Consumer-Related Food Waste: Causes and Potential for Action

Directory of Open Access Journals (Sweden)

Jessica Aschemann-Witzel

2015-05-01

Full Text Available In the past decade, food waste has received increased attention on both academic and societal levels. As a cause of negative economic, environmental and social effects, food waste is considered to be one of the sustainability issues that needs to be addressed. In developed countries, consumers are one of the biggest sources of food waste. To successfully reduce consumer-related food waste, it is necessary to have a clear understanding of the factors influencing food waste-related consumer perceptions and behaviors. The present paper presents the results of a literature review and expert interviews on factors causing consumer-related food waste in households and supply chains. Results show that consumers’ motivation to avoid food waste, their management skills of food provisioning and food handling and their trade-offs between priorities have an extensive influence on their food waste behaviors. We identify actions that governments, societal stakeholders and retailers can undertake to reduce consumer-related food waste, highlighting that synergistic actions between all parties are most promising. Further research should focus on exploring specific food waste contexts and interactions more in-depth. Experiments and interventions in particular can contribute to a shift from analysis to solutions.

Instruments for analysing the influence of advertising on children's food choices.

Gwozdz, W; Reisch, L A

2011-04-01

The aim of this report was to present methodological aspects of assessing the effects of advertising on children's food choices and preferences. Two instruments have been used: first, a choice experiment on children's food knowledge and preferences, and second, a questionnaire on children's knowledge about and attitudes towards advertising. The choice experiment employed 10 matched pairs of food items, each represented in two magazines, one that tested knowledge and the other food preferences. The children's questionnaire contained four dimensions that tested children's credibility and suspiciousness of, as well as entertainment by, advertising. Although based on already developed tools, both instruments were modified to suit the young target group and ensure cross-cultural comparability. The questionnaire was validated via Cronbach's alpha and factor analysis. A total of 393 children aged 5-11 years from seven European countries participated in the study. Both instruments proved to be valid and reliable to analyse the food knowledge and preferences of children, as well as knowledge about and attitudes towards advertising. While 92.2% of the children predominantly recognised the healthier food, only 33.2% also preferred the healthier food. The Cronbach's alpha values for the dimensions were 0.470 for credibility, 0.409 for suspiciousness and 0.295 for entertainment factor. The gathered data revealed that children are rather critical and suspicious of advertising and only moderately entertained. Both instruments are applicable for the 5- to 11-year-old age group in different European countries. Descriptive results indicate additional insights into the effects of advertising on children's food knowledge, preferences and food choice.

Zooplankton taxonomic and size diversity in Mediterranean coastal lagoons (NE Iberian Peninsula): Influence of hydrology, nutrient composition, food resource availability and predation

2007-01-01

The influence of hydrology, nutrient composition, food resource availability and predation on zooplankton taxonomic and size diversity was analyzed in several shallow lagoons of a Mediterranean salt marsh (Baix Ter Wetlands, NE Iberian Peninsula). Taxonomic diversity correlated better with variables related to the trophic state, such as nutrient concentrations, whereas size diversity was more sensitive to fish predation. However, the fish predation influence on the size diversity was only significant when fishes reached high densities. Under low fish densities no predation effects were observed and the food resource availability (FR a) appeared to be more important in structuring the zooplankton community. Nevertheless, the two diversity indexes showed opposite responses to this factor. With increasing FR a the taxonomic diversity increased and the size diversity decreased. Neither taxonomic nor size diversity of the zooplankton community correlated with other physical or biotic factors such as hydrological variability or macroinvertebrate predation. The relationships found suggest that the size diversity is mainly related to biotic interactions, such as fish predation or inter/intraspecific competition, while the taxonomic diversity appears to be more sensitive to abiotic factors such as the nutrient composition.

Motives for food choice among Serbian consumers

Gagić Snježana

2014-01-01

Full Text Available People's motives for food choice depend on a number of very complex economic, social and individual factors. A Food Choice Questionnaire (FCQ, an instrument that measures the importance of factors underlying food choice, was used to reveal the Serbian consumers' food choice motives by survey of 450 respondents of different age groups. A confirmatory factor analysis was conducted on the motive items, using 11 factors. Previous research shows that the nutrition in Serbia is not balanced enough, and therefore the analysis of motives for food choice is considered a useful tool for the planning of more efficient public policies and interventions aimed at influencing healthier eating habits. Hence the results can be useful for researchers as well as for public institutions which deal with creating the strategy of public health or businessmen who produce and sell food products, because knowing consumer behaviour is necessary for product success on the market.

2011-01-01

It is recognised that eating habits established in early childhood may track into adult life. Developing effective interventions to promote healthier patterns of eating throughout the life course requires a greater understanding of the diets of young children and the factors that influence early dietary patterns. In a longitudinal UK cohort study, we assessed the diets of 1640 children at age 3 years using an interviewer-administered FFQ and examined the influence of maternal and family factors on the quality of the children's diets. To describe dietary quality, we used a principal components analysis-defined pattern of foods that is consistent with healthy eating recommendations. This was termed a 'prudent' diet pattern and was characterised by high intakes of fruit, vegetables and wholemeal bread, but by low intakes of white bread, confectionery, chips and roast potatoes. The key influence on the quality of the children's diets was the quality of their mother's diets; alone it accounted for almost a third of the variance in child's dietary quality. Mothers who had better-quality diets, which complied with dietary recommendations, were more likely to have children with comparable diets. This relationship remained strong even after adjustment for all other factors considered, including maternal educational attainment, BMI and smoking, and the child's birth order and the time spent watching television. Our data provide strong evidence of shared family patterns of diet and suggest that interventions to improve the quality of young women's diets could be effective in improving the quality of their children's diets.

This study investigates the association between traditional food consumption and motives for food choice in six European countries. Cross-sectional data were collected through the TRUEFOOD pan-European consumer survey (n = 4828) with samples representative for age, gender and region in Belgium, France, Italy, Norway, Poland and Spain. Importance attached to familiarity with a product is found to be strongly and positively associated with general attitude toward traditional food as well as traditional food consumption. The importance attached to convenience was negatively related to both general attitude toward traditional food and traditional food consumption, while the importance of weight control negatively influenced the general attitude. Natural content of food was positively associated with the attitude toward traditional food and traditional food consumption. The importance of price when purchasing food failed to be significantly related with general attitude and traditional food consumption both for the pooled sample as well as within each country except in Spain. The proposed model contributes to a better understanding of factors shaping the image and influencing the consumption of traditional foods in Europe. General attitude toward traditional foods, familiarity, and importance of food naturalness emerged as drivers for traditional food consumption. Importance attached to convenience and health acted as direct barriers to traditional food consumption, whereas importance of weight control emerged as an indirect barrier through lowering general attitude toward traditional foods.

Food choice is influenced by consumer attitudes towards food attributes. This U.S.-based study (n = 601) simultaneously compares attitudes towards selected food attributes of organic, locally grown, U.S. grown, and GM-free food in relation to other food attributes. Exploratory factor analysis identifies underlying constructs that determine, together and separately, female and male food choice decisions. Gendered analysis of the value of food in life and food behaviours (cooking and shopping) support the investigation of the highlighted food attributes. Respondents generally assigned greater importance to the U.S. grown, followed by GM-free, locally grown, and organically produced food attributes in deciding what to eat. Analysis of the female and male subsamples yielded similar factor results. All four main attributes were captured in a single factor, associated with respondents in both the female and male subsamples who are older, have lower incomes, and who are religiously observant. Additionally, among females, this factor was associated with higher education; and among males, living in households with children and/or with partners. Additional studies should further explore the interaction of food attributes now becoming increasingly important and prevalent in current food products. Copyright © 2010 Elsevier Ltd.

2014-10-01

Full Text Available Packaging is an important instrument of commerce and trade in the world, it plays essential role in increasing sales and export and thus it maximizes profits generated in enterprises. Hence, the appropriate packaging for the producer generates necessary incentives for production, partly preserves them against zany opponents, and finally provides the customer with much more variety and choosing the right products. Packaging in fact, is a major contributor to the performance of customer relationship management. This survey determines five packaging factors influencing on export development including communications, infrastructure, awareness, design and technical extraction. Through the implementation of principal component analysis, the effective role of packaging components on exports is measured. Exploratory research model indicates that all five packing components were effective in export development of food industry.

An exponential increase of PBDE levels in breast milk from Sweden between 1972 and 1997 has been reported, which is in contrast to the continuous decline of other chlorinated POPs in breast milk. Also in blood samples from Germany, an increasing trend has been observed during the period from 1985 to 1999. The knowledge about human exposure pathways, which contribute to the PBDE body burden, is very limited. Consumption of food of animal origin, inhalation or ingestion of dust and further factors possibly influencing the PBDE levels in human matrices, like age, breast-feeding or smoking are under discussion. Only a few data on PBDE levels in breast milk from Germany have been published. To fill the data gaps, a controlled study was started in 2001 to characterise the PBDE levels in human milk from Germany with special efforts to identify and quantify deca-BDE-209. Furthermore, it was intended to verify potential factors possibly influencing PBDE levels. Two main hypotheses were proposed: (1) Are PBDE levels in breast milk from mothers consuming traditional food (omnivores) higher than those found in breast milk from mothers consuming vegetarian or vegan food? and (2) Are the PBDE levels found in human milk after a three-months period of breast-feeding lower than those detected at the beginning or does breast feeding result in a lower body burden, respectively? This paper summarises preliminary results. Further analytical data and results of data evaluation will be presented at the conference.

Food preferences have been identified as a key determinant of children's food acceptance and consumption. The aim of this study was to identify factors that influence children's liking for fruits, vegetables and non-core foods. Participants were Australian mothers (median age at delivery=31years, 18-46years) and their two-year-old children (M=24months, SD=1month; 52% female) allocated to the control group (N=245) of the NOURISH RCT. The effects of repeated exposure to new foods, maternal food preferences and child food neophobia on toddlers' liking of vegetables, fruits and non-core foods and the proportion never tried were examined via hierarchical regression models; adjusting for key maternal (age, BMI, education) and child covariates (birth weight Z-score, gender), duration of breastfeeding and age of introduction to solids. Maternal preferences corresponded with child preferences. Food neophobia among toddlers was associated with liking fewer vegetables and fruits, and trying fewer vegetables. Number of repeated exposures to new food was not significantly associated with food liking at this age. Results highlight the need to: (i) encourage parents to offer a wide range of foods, regardless of their own food preferences, and (ii) provide parents with guidance on managing food neophobia.

Radiopreservation of food is a technological process which is ensuring quality and durability of food. Food materials are irradiated by ionising radiation to reduce biological activity in foodstuffs. From this point of view, application of food irradiation is equivalent process to the other technological procedures ensuring good quality of food such as sterilisation by low or high temperature and chemicals factors. Although the sterilisation by ionising radiation has been limited by controversial effects in general, irradiated technologies of more than 40 products were accepted in several countries. Radiopreservation of food is spread mainly in the U.S.A. where ionizing radiation is even using for enhancement of several visual factors of food for instance the color. The countries of European Union accepted similar standards for radiopreservation of food and ingredients. They determined the kind of food materials, the convenient doses of irradiation and other conditions at ionizing radiation using for food preservation. Number of food is limited by toxicological aspects and unknown behaviour of radiation within food material (e.g. secondary radiation). For this reason, it is necessary to study the effects of food irradiation and find out its mediate influence on human organism. (authors)

Factors influencing the transfer of radionuclides in agricultural food chains

The applications of nuclear energy have led and will continue to lead to routine or accidental discharges of radioactive elements into the atmospheric and/or aquatic environment resulting in the exposure of populations to ionising radiations. The radionuclides released into the atmosphere are transported downwind, dispersed by the atmospheric mixing phenomena and progressively settled by deposition processes. During the passage of the radioactive cloud, people are irradiated externally as well as internally by inhalation. After the passage of the cloud, exposure of the population continues via three main pathways: external irradiation from the radionuclides deposited on the ground, inhalation of resuspended contaminated particles and ingestion of contaminated food products. When discharged into aquatic systems, the radionuclides can be partly removed from the aqueous phase by adsorption on suspended solids and bottom sediments. As the radioactivity disperses, there is a continuing exchange between water and solid phases. The contaminated sediments deposited on the banks of rivers, lakes and coastal area lead to external irradiation of people spending time at these sites. The residual activity in water exposes man internally through the ingestion of drinking water and food products, contaminated by irrigation of vegetation and ingestion of water by livestock. Among the various exposure pathways, the main route of entry of fission products and most other artificial radionuclides into man has been identified as uptake from the diet. Since agricultural products constitute the basic diet of most populations, the fate and behavior of radionuclides in agricultural ecosystems are of primary importance when assessing the exposure risk of man from environmental releases of radioactivity. 69 refs., 4 figs

Highlights: • The basic information of China’s food industry is introduced in detail. • Inter-factor substitution relationship in China’s food industry is analyzed. • Direct rebound effect in the industry is measured. • Several relevant policy suggestions about energy conservation are provided. - Abstract: Energy efficiency improvement can reduce the energy consumption of an industry, and thus promote energy conservation. However, the reduction of effective energy prices caused by energy efficiency improvement will lower energy costs for enterprises, making them substitute energy for other input factors. Therefore, energy conservation brought about by efficiency improvement will be partly offset. This offset is called the energy rebound effect of an industry. This paper estimates the system of cost share equations in China’s food industry, analyzes the substitution relationship between each input factor, and calculates the direct rebound effect. The results show that: there exist substitution relationships between energy and other input factors, among which the substitution elasticity between energy and labor is the biggest, and the substitution of energy for capital dominates that of capital for energy. The direct rebound effect is approximately 34.39%, which means that about 34.39% of energy conservation caused by energy efficiency enhancement in the industry has been offset by the rebound effect. The paper proposes some policy suggestions on energy conservation according to the results of substitution relationship among input factors and the rebound effect of the industry. The policy suggestions include reducing the capital and labor costs of the food industry by decreasing financing costs of small businesses, optimizing personnel management, and rationalizing the energy pricing mechanism to form a reasonable energy price.

The application of electrostatics in both powder and liquid coating can improve the quality of food, such as its appearance, aroma, taste, and shelf life. Coatings can be found most commonly in the snack food industry, as well as in confectionery, bakery, meat and cheese processing. In electrostatic powder coating, the most important factors influencing coating quality are powder particle size, density, flowability, charge, and resistivity, as well as the surface properties and characteristics of the target. The most important factors during electrostatic liquid coating, also known as electrohydrodynamic coating, include applied voltage and electrical resistivity and viscosity of the liquid. A good understanding of these factors is needed for the design of optimal coating systems for food processing.

In a random sample (N = 951) from the general population, direct and indirect effects of the Big Five personality traits on eating styles and food choices were examined. Path models revealed that high openness to experience were associated with higher fruit, vegetable and salad and lower meat and soft drink consumption. High agreeableness was associated with low meat consumption. Neuroticism, conscientiousness and extraversion significantly and directly influenced eating styles and significantly indirectly influenced food choices. Conscientiousness mainly promoted fruit consumption by promoting restrained eating and prevented meat consumption by reducing external eating. Conscientiousness prevented consumption of sweet and savory foods, and of sugar-sweetened soft drinks by promoting restrained eating and reducing external eating, and consumption of sweet and savory foods also by reducing emotional eating. Neuroticism promoted consumption of sweet and savory foods by promoting emotional and external eating. Extraversion promoted sweet and savory, meat and soft drink consumption via promoting external eating. Results suggest that neurotic and emotionally unstable individuals seem to adopt counter-regulatory external or emotional eating and eat high-energy dense sweet and savory foods. Highly conscientious individuals adopt regulatory dietary restraint and practice counter-regulatory emotional or external eating less, resulting in more consumption of recommended and less consumption of not recommended food. The higher sociability of extraverted people, which is basically a health beneficial psychological resource, seems to have health-averse effects. Personality traits are stable; however, the resulting more proximal, counter-regulatory eating styles such as emotional or external eating might be more successfully addressed in interventions to prevent overeating and overweight.

Production of sufficient, safe and nutritious food is a global challenge faced by the actors operating in the food production chain. The performance of food-producing systems from farm to fork is directly and indirectly influenced by major changes in, for example, climate, demographics, and the economy. Many of these major trends will also drive the development of food safety risks and thus will have an effect on human health, local societies and economies. It is advocated that a holistic or system approach taking into account the influence of multiple "drivers" on food safety is followed to predict the increased likelihood of occurrence of safety incidents so as to be better prepared to prevent, mitigate and manage associated risks. The value of using a Bayesian Network (BN) modelling approach for this purpose is demonstrated in this paper using food fraud as an example. Possible links between food fraud cases retrieved from the RASFF (EU) and EMA (USA) databases and features of these cases provided by both the records themselves and additional data obtained from other sources are demonstrated. The BN model was developed from 1393 food fraud cases and 15 different data sources. With this model applied to these collected data on food fraud cases, the product categories that thus showed the highest probabilities of being fraudulent were "fish and seafood" (20.6%), "meat" (13.4%) and "fruits and vegetables" (10.4%). Features of the country of origin appeared to be important factors in identifying the possible hazards associated with a product. The model had a predictive accuracy of 91.5% for the fraud type and demonstrates how expert knowledge and data can be combined within a model to assist risk managers to better understand the factors and their interrelationships.

Objectives: The study evaluates the influence of ICTs in improving food security in KwaZulu-Natal Province. A theoretical framework was developed as the lens through which diffusion and adoption of ICTs can be understood. The theorised model was developed using constructs from the diffusion of innovation (DOI theory, technology acceptance model (TAM and Hofstede’s cultural dimensions theory. Method: Survey data from 517 smallholder farmers from the district municipality of iLembe were collected using a questionnaire. A quantitative approach was followed, and the developed theorised model was analysed using structural equation modelling techniques. Results: This study proposes that ICT influence on food security is associated with culture, perceived usefulness and perceived ease of use. The study further finds that perceived ease of use of ICTs has the most significant effect with regard to ICT adoption and diffusion amongst smallholder farmers in iLembe district municipality. There are, however, no associations found with perceived attributes of innovation and the nature of social systems. The study consisted of a largely homogeneous social system; therefore, the researcher could not make any comparisons. Conclusion: The proposed framework for evaluating the influence of ICTs on food security put forward in this study highlights a number of issues. Firstly, there is need for further study to be conducted to understand adoption of ICTs specifically for food security. This would help in creating more accurate adoption strategies. Secondly, the study informs ICT innovation developers on the need to prioritise ease of use of ICT-based interventions when developing innovations that focus on smallholder farmers. The study also contributes to policy guidelines and suggests clear guidelines be developed to address cultural aspects such as gender imbalances.

Fermented foods are among the food products more often complained of having caused episodes of biogenic amines (BA) poisoning. Concerning milk-based fermented foods, cheese is the main product likely to contain potentially harmful levels of BA, specially tyramine, histamine, and putrescine. Prompted by the increasing awareness of the risks related to dietary uptake of high biogenic amine loads, in this review we report all those elaboration and processing technological aspects affecting BA biosynthesis and accumulation in dairy foods. Improved knowledge of the factors involved in the synthesis and accumulation of BA should lead to a reduction in their incidence in milk products. Synthesis of BA is possible only when three conditions converge: (i) availability of the substrate amino acids; (ii) presence of microorganisms with the appropriate catabolic pathway activated; and (iii) environmental conditions favorable to the decarboxylation activity. These conditions depend on several factors such as milk treatment (pasteurization), use of starter cultures, NaCl concentration, time, and temperature of ripening and preservation, pH, temperature, or post-ripening technological processes, which will be discussed in this chapter.

Households in the UK discard much food. A reduction in such waste to mitigate environmental impact is part of UK government policy. This study investigated whether household food waste is linked to a lifestyle reliant on convenience food in younger consumers. A survey of 928 UK residents aged 18-40 years and responsible for the household food shopping (male n = 278; female n = 650) completed an online questionnaire designed to measure attitudes to convenience food and to quantify household food waste. Cluster analysis of 24 food-related lifestyle factors identified 5 consumer groups. General linear modelling techniques were used to test relationships between the purchase frequency of convenience food and household food waste. From the cluster analysis, five distinct convenience profiles emerged comprising: 'epicures' (n = 135), 'traditional consumers' (n = 255), 'casual consumers' (n = 246), 'food detached consumers' (n = 151) and 'kitchen evaders' (n = 141). Casual consumers and kitchen evaders were the most reliant on convenience food and notably were the most wasteful. The demographic profile of kitchen evaders matched the population groups currently targeted by UK food waste policy. Casual consumers represent a new and distinct group characterised by "buy a lot and waste a lot" behaviour. Household size, packaging format, price-awareness and marketing all appear to influence levels of food waste. However, it seems that subtle behavioural and sociocultural factors also have impact. Further research is needed to elucidate the factors that mediate the positive association between the purchase of convenience food and reported food waste in order to inform food waste policy and initiatives.

The purpose of this study was to investigate food habits and preferences against menu planning for heterogeneous groups in institutions and to determine to what extent these results on food habits and preferences can be applied to practical recommendations in menu planning for heterogeneous groups. This study used data from a sample of students to determine whether food habits and preferences influence students' own menu planning and that of other eating outlets. A sample of 60 students within the University of Cape Coast campus was considered for this study. Findings from the study revealed that a greater number of students have altered their food habits over the years. This was attributed greatly to health factors, change of environment and education. The recommendations made in this study include encouraging cooking competitions among young people to expose them to traditional meals/dishes, which show culinary prowess, and also holding food fairs and encouraging teaching cooking methods for traditional dishes to children.

Factors influencing consumer dietary health preventative behaviours.

The deterioration of the health status of the Romanian population during the economic transition from a centrally planned to a free market economy has been linked to lifestyles factors (e.g. diet) regarded as a main determinants of the disparity in life expectancy between Eastern and Western Europe. Reforms in the health care system in this transition economy aim to focus on preventive action. The purpose of this study was to identify the factors that impact on the individual decision to engage in Dietary Health Preventive Behaviour (DHPB) and investigate their influence in the context of an adapted health cognition model. A population-based study recruited 485 adult respondents using random route sampling and face-to-face administered questionnaires. Respondents' health motivation, beliefs that diet can prevent disease, knowledge about nutrition, level of education attainment and age have a positive influence on DHPB. Perceived barriers to healthy eating have a negative impact on alcohol moderation. The information acquisition behaviour (frequency of reading food labels) is negatively predicted by age and positively predicted by health motivation, education, self-reported knowledge about nutrition and household financial status. A significant segment of respondents believe they are not susceptible to the elicited diseases. Health promotion strategies should aim to change the judgments of health risk. The adaptation of the Health Belief Model and the Theory of Health Preventive Behaviour represents a valid framework of predicting DHPB. The negative sign of perceived threat of disease on DHPB may suggest that, under an income constraint, consumers tend to trade off long-term health benefits for short-term benefits. This cautions against the use of negative messages in public health campaigns. Raising the awareness of diet-disease relationships, knowledge about nutrition (particularly sources and risks associated with dietary fat and cholesterol) may induce people to
