ABSTRACT

El DHA es un nutriente crítico en mujeres embarazadas y en lactancia, con importantes beneficios en el desarrollo cerebral y agudeza visual del lactante. En Chile el consumo de DHA representa menos del 30% de las recomendaciones internacionales para el embarazo. El objetivo del estudio fue diseñar y evaluar una bebida láctea para embarazadas y nodrizas adicionada de 60 mg de DHA y 11 de EPA por porción de consumo (200 mi), además de estar fortificada con vitaminas y minerales. Se estudió una cohorte de 177 embarazadas que recibieron 2 Kg. mensuales de bebida láctea en comparación con un grupo control de 175 embarazadas que recibió el producto actualmente en uso en el Programa Nacional de Alimentación Complementaria (leche 26% de materia grasa, fortificada con Fe, Zn y vit C). Se evaluó aceptabilidad, tolerancia y consumo de ambos productos en dos oportunidades en el embarazo y a los 2 meses posparto. Ambos alimentos fueron bien evaluados en sus características organolépticas. El consumo promedio de ambos grupos fue 1,8 +/- 1,0 tazas diarias, inferior a las 3 tazas programadas. Durante el embarazo la evaluación sensorial y el consumo fueron mayores para la leche entera, aunque las diferencias no fueron importantes desde el punto de vista biológico. Durante la lactancia no hubo diferencias en ninguno de los parámetros evaluados. Se concluye que la bebida láctea es una buena alternativa para mejorar el consumo de DHA durante el embarazo y lactancia.


DHA is a critical nutrient for pregnant and lactating women, with important functions in brain development and sight acuity of the newborn. In Chile, DHA intake represents less than 30% of the international recommendation for pregnancy. The objective of this study was to design and evaluate a milk drink for pregnant and lactating women, containing 60 mg of DHA and 11 mg of EPA per 200 mi portion, plus other added vitamins and minerals. A cohort of 177 pregnant women received 2 kg/month of the milk drink and compared to a group ofl75 women receiving the regular milk distributed by the National Complementary Feeding Program (PNAC), consisting of whole milk powder (26% fat) fortified with Fe, Zn, and Vitamin C. Evaluation included acceptability tests, tolerance, and intake of both milks, and measurements were performed at two moments during pregnancy, and after two months of lactation. Both milks had good evaluations in their organoleptic characteristies. Average intake for both groups was 1.8 +/- 1 cup per day, lower than the three cups per day that were originally defined for the study. During pregnancy, sensory evaluation was better, and intake was higher, than with the regular whole milk, although these differences were not significant from a biological standpoint. During lactation, there were no differences among any of the evaluated parameters. The developed milk drink constitutes a good alternative for improving DHA intake during pregnancy and lactation.
