In recent years, many different nations and age groups have conducted extensive research on the growth and nutritional intake of children with cow’s milk allergy and other dietary allergies. Atopic children’s stunted growth should not be ascribed just to a high number of allergens and foods to avoid, but to a general state of “sub-inflammation,” which negatively affects the absorption and utilization of fuel and substrates. Atopic research participants may be an excellent target for customized nutrition, and researchers attempted to describe several of the problems that should be considered when dietitians counsel patients about food avoidance and predicted consequences on growth and health in this review. Food allergy management necessitates optimal nutritional choices to ensure healthy development, beginning with specific formulas in infancy. The fussy eating associated with the exclusion of cow’s milk and other foods during infancy, as well as the long-term consequences on eating habits and dietary preferences, is an emerging topic of research.

Participants in studies with mono- or poly allergic illnesses should preferably have their allergic and metabolic features defined in order to accurately tailor dietary treatments on an individual basis to promote the genetic potential of growth and avoid adverse consequences.
