Outcome of food intake and nutritional status after discontinuation of a cow’s-milk-free diet post negative oral food challenge in infants and children

Objective To evaluate the outcome of food intake and nutritional status post discontinuation of a cow’s-milk-free diet after a negative oral food challenge.Methods This was a prospective, uncontrolled study that evaluated food intake and nutritional status of a cohort of 80 infants and children under 5 years of age. Food intake and nutritional status were evaluated on the day of the oral food challenge test and after 30 days. Weight and height were measured on the day of the test and after 30 days.Results The mean age of the patients was 18.7 ± 12.4 months, and 58.7% were male. After discontinuation of the elimination diet, the children showed daily intake increases in (P < 0.001), protein (P < 0.001), carbohydrates (P = 0.042), calcium from foods (P < 0.001), calcium from foods and supplements (P < 0.001), phosphorus (P < 0.001), and vitamin D from foods (P = 0.006). The Z-scores (n = 76) on the day of the oral food challenge test and 30 days after restarting the consumption of cow’s milk were as follows: weight-for-age (P < 0.001) and height-for-age (P < 0.001), respectively.Conclusion Cow’s milk protein in the diet was associated with increased intake of energy, proteins, carbohydrates, calcium, phosphorus, and vitamin D, in addition to an increase in the Z-scores for weight-for-age and height-for-age (aU)
