Early exposure to allergens : a new window of opportunity for non-communicable disease prevention in complementary feeding?

Recent findings suggest that an early exposure to dietary antigens may be more protective towards allergy than a later introduction even in high-risk infants. The consequent earlier introduction of food items such as egg yolk and oily fish, together with breastfeeding continuation through the first year, could contribute to reducing protein and increasing fat supply, respectively. These changes might have a role in the overall prevention of non-communicable disorders of adulthood.
