RESUMEN
INTRODUCTION AND OBJECTIVES: Food allergy has several negative nutritional consequences and may persist beyond the first year of lives. This study aimed to assess the role of a complete oral amino acid-based supplement in the diet of children on cow's milk protein elimination diet because of food allergy. MATERIALS AND METHODS: This study included two groups of children aged 1-5 years paired by age and socioeconomic status: (1) study group, on cow's milk protein elimination diet plus an oral amino acid-based supplement, and (2) control group, on cow's milk protein elimination diet. Sociodemographic, clinical, anthropometric, and dietary data were obtained through online interviews. Two 24-h dietary recalls were collected on nonconsecutive days. Both groups comprised mostly boys. RESULTS: The study group presented lower values of body mass index. The frequency of feeding difficulties was similar between groups. The study group had a higher intake of energy, protein, carbohydrates, calcium, iron, zinc, phosphorus, magnesium, copper, selenium, vitamins D, E, B1, B2, B6, and B12, niacin, and folic acid compared to the control group. A higher proportion of children in the study group had adequate intake according to the recommendations made for energy, carbohydrates, iron, phosphorus, selenium, vitamins A, D, E, B1, B2, and B6, and folic acid. CONCLUSIONS: The use of a complete oral amino acid-based supplement has a positive effect on the diet quality of preschoolers on cow's milk elimination diet because of food allergy, promoting higher intake of energy, calcium, vitamin D, and other essential nutrients.
