Abstract:
Food allergies and atopic diseases are on the rise worldwide. There have been several published practice guidelines on the primary prevention of these diseases. One aspect of these guidelines is the recommendations on infant nutrition, as food allergen exposure and other nutritional factors may influence allergen sensitization. This article aims to review the current international recommendations on infant diet and weaning practices in the primary allergy prevention of infants. The conclusions drawn are as follows: (1) Breastfeeding is considered the gold standard for infant nutrition, especially since exclusive breastfeeding confers some protection against the development of allergic diseases. However, large cohort studies have not been carried out in Asian populations. (2) Maternal avoidance of allergenic food substances during pregnancy and lactation has not been proven to reduce the risk of allergies and is not recommended as a primary prevention strategy. (3) Hydrolyzed formulas have not been shown to have an advantage over breastfeeding, although they have some protective value against atopic eczema in at risk infants when compared to regular cows milk based infant formula. (4) Soy formula is also not recommended for prevention of atopic diseases. (5) Weaning to semisolids should be undertaken between the ages of 4 to 6 months as weaning before the age of 4 months is associated with increased of allergy symptoms. (6) The age for introduction of certain highly allergenic foods have been arrived at empirically and included in some guidelines. These comprise the initiation of dairy products at 12 months, eggs at 24 months, and peanuts, nuts and fish at 36 months.
