CHICAGO — Breast-feeding helps prevent babies' allergies, but there's no good evidence for avoiding certain foods during pregnancy, using soy formula or delaying introduction of solid foods beyond six months.

That's the word from the American Academy of Pediatrics, which is updating earlier suggestions that may have made some parents feel like they weren't doing enough to prevent food allergies, asthma and allergic rashes.

In August 2000, the medical group advised mothers of infants with a family history of allergies to avoid cow's milk, eggs, fish, peanuts and tree nuts while breast-feeding.

That advice, along with a recommended schedule for introducing certain risky foods, left some moms and dads blaming themselves if their children went on to develop allergies.

"They say, 'I shouldn't have had milk in my coffee,' " said Dr. Scott Sicherer of the Mount Sinai School of Medicine's Jaffe Food Allergy Institute in New York. "I've been saying, 'We don't really have evidence that it causes a problem. Don't be on a guilt trip about it.' "
