Breastfeeding may lower allergy risk
Jan 9, 2008
Exclusive breastfeeding for at least four months may help prevent asthma eczema, and food allergies in high-risk babies, but there is little evidence that delaying the introduction of specific foods makes a difference, the nation's leading group of pediatricians now says.
A previous call for the gradual introduction of foods typically associated with allergies in high-risk children.
The earlier guidelines recommended delaying the introduction of cow's milk until after a child's first birthday, eggs until age 2, and tree nuts, peanuts, and fish until age 3.
"If a child is going to be allergic to peanuts or eggs, it doesn't seem to matter [after 4 to 6 months] when you introduce these foods".
There is also no convincing evidence to justify telling moms to avoid these foods during pregnancy and while they are nursing, the new report shows.
.Among the major findings:
- Exclusive breastfeeding for at least four months, compared with feeding regular formula made from cow's milk, appears to help protect high-risk children against milk allergy and eczema in the first two years of life, the report states.
- There is "modest evidence" that special formulas that are extensively or partially hydrolyzed may prevent eczema in infants
- More study is needed to determine whether the benefits of these extensively or partially hydrolyzed formulas for allergic disease prevention extend into later childhood and adolescence.
- There is "no convincing evidence" that soy-based formulas help prevent allergic disease in high-risk children.
"If there is a family history of allergy problems, it is clear that moms should breastfeed exclusively for at least four months”.
Long-Term Impact Unknown
The new guidelines apply only to babies with a high risk of developing allergic disease, not those who already have asthma, food allergies, or eczema.
The authors conclude that more research is needed to document the long-term effect of dietary interventions in infancy for preventing allergic disease after early childhood.
Doing away with the recommendation to delay the introduction of certain foods will probably have little practical impact because few parents were following them.the food restriction guideline may have even made the parents of children with allergic diseases feel responsible.
"Moms who think they caused their child's milk allergy or egg allergy by introducing these foods too soon can relax.
