There are, thus far, no guarantees that parents can prevent allergies in any one particular child. However, the American Academy of Pediatrics (AAP) has put forth some guidelines that, over large population groups, are believed to help prevent food allergies in high-risk children (those with parents or siblings with food allergies or other allergic disorders, like eczema):
- Breastfeed exclusively for at least four to six months, if possible.
- Breastfeeding isn't possible, desirable, or workable in some circumstances. In these cases, doctors will likely recommend or prescribe hydrolysate formulas -- formulas that have been broken down into simpler proteins that are considered easier to digest. At this time, extensively hydrolyzed formulas are considered the most effective for preventing allergic conditions.
- Wait until infants are four to six months old to introduce solid foods.
In January 2008, the American Academy of Pediatrics reversed its stance on delaying the introduction of common allergens like dairy, eggs, and nuts, stating that there was "no current convincing evidence that delaying their introduction beyond [the age of four to six months] has a significant protective effect on the development of atopic disease."
This means that, contrary to earlier recommendations, it is now the AAP's stance that dairy, eggs, peanuts, tree nuts, and seafood are safe to introduce to your baby at the same time you introduce other foods. As always, however, your allergist or pediatrician is the best source for specific recommendations for your family.
