Two new studies bolster evidence that feeding babies peanuts or other allergy-inducing foods is more likely to protect them than to cause problems. One study, a follow-up to landmark research published last year, suggests that the early prevention strategy leads to persistent, long-lasting results in children at risk for food allergies. It found that allergy protection lasted at least through age 5 and didn't wane even when kids stopped eating peanut-containing foods for a year. (AP Photo/Patrick Sison, File)
