In the diet of infants and young children, from breastfeeding to the consumption of dairy products or infant formula, and non-staple foods, the flavor of the chosen foods by these infants and young children would actually influence their future food preferences. Besides, these choices could potentially lead to deviations in diet, which may increase the risk of chronic diseases. Therefore, in terms of formula design, infant dietary supplements should specially avoid any food additives that do not come from the original taste of natural food, especially flavoring agents such as artificial fruit flavors.
