Resumen en español El objetivo del estudio fue valorar el aporte energético, de antioxidantes y de poliaminas de la ingesta, iniciándose desde las primeras 24 horas inmediatas a la quemadura. La valoración nutricional se realizó a los 7, 15 y 21 días y se comparó con el grupo control (n = 30). La edad de los pacientes (n = 25; 20 hombres y 5 mujeres) fue de 45,6 ± 20,4 años. Veintiún pacientes presentaron una superficie corporal quemada (SQC) entre el 20-50% y en 4 casos fue superi (mas) or al 50%. Se observó un descenso del aporte energético medio de ~40% vs el teórico calculado en los 3 períodos: 1.186 ± 32, 1.117 ± 589 y 1.331 ± 578 kcal. En los primeros 15 días la ingesta de antioxidantes fue ligeramente inferior a las RDA para la vitamina C: 60 mg vs 57 ± 32, 57 ± 53 y 75 ± 53 mg, e inferior durante todo el período para la vitamina E: 10 mg vs 5,0 ± 2,9; 4,5 ± 3,0 y 5,3 ± 3,4 mg, selenio: 40 µg vs 22,8 ± 13,7, 22,5 ± 9,8 y 25,7 ± 11,2 µg y zinc: 12 mg vs 7.3 ± 3.0; 6,8 ± 4,8 y 8.4 ± 5,3 mg. La ingesta de taurina descendió en el día 15 y se incrementó significativamente en el día 21: 65,7 ± 30 mg, 50,9 ± 25 y 72,0 ± 29 mg (p Resumen en inglés Starting the first 24 hours after burn injury, energy supply, antioxidants and polyamines were assessed in 25 severe burn patients (20 men and 5 women) with a mean age of 45.6 ± 20.4 years. Nutritional assessment was performed at 7, 15 and 21 days and was compared with a control group (n = 30). In 21 patients the burned body surface area was 20%-50% and in four patients it was greater than 50%. A mean decrease in energy supply of ~40% versus the calculated theoretical va (mas) lue was found in the three periods: 1,186 ± 32; 1,117 ± 589 and 1,331 ± 578 kcal. In the first 15 days antioxidant ingestion was slightly lower than the recommended daily allowance for vitamin C: 60 mg versus 57 ± 32, 57 ± 53 and 75 ± 53 mg, and was lower during the entire period for vita-min E: 10 mg versus 5.0 ± 2.9; 4.5 ± 3.0 and 5.3 ± 3.4 mg; selenium: 40 µg versus 22.8 ± 13.7; 22.5 ± 9.8 and 25.7 ± 11.2 µg and zinc: 12 mg versus 7.3 ± 3.0, 6.8 ± 4.8 and 8.4 ± 5.3 mg. Taurine ingestion decreased on day 15 and significantly increased on day 21: 65.7 ± 30 mg, 50.9 ± 25 and 72.0 ± 29 mg (p
