Introduction and Maintenance of Still Eating Protein Blends in Support of Infant Nutritional Goals

The study involves parents/caregivers of infants, ≥ 5 months but < 11 months of age. Parents who enrolled their infants complete a 1‐month blinded placebo run‐in period, followed by randomization to placebo or the food supplement. During the intervention period, infants randomized to the food supplement are fed a once daily, individual packet of the food supplement mixed into liquid (e.g., breast milk, infant formula) or solid (e.g., applesauce, pureed carrots) foods being fed to the infant. The food supplement is a blend of 16 common allergenic proteins ([oat, milk, egg, sesame, wheat] [almond cashew, hazelnut, peanut, pecan, pistachios, soy, walnut] [cod, shrimp, salmon]) combined with 400 IU of Vitamin D3. Parents complete a daily diary about any reactions or symptoms within 2 hours of ingesting the food supplement. Infants randomized to the placebo are also fed a once daily individual packet of the placebo mixed into liquid or solid foods being fed to the infant. Parents also complete a daily diary about any reactions or symptoms within 2 hours of ingesting the placebo.
