A new study of Jewish children in Israel and the UK suggests that early exposure to peanuts significantly reduces the risk of peanut allergy. What the article describing the study doesn't say is that most Israeli infants are introduced to a peanut snack called "Bamba" as one of their first foods. We started giving Natalie Bamba at around eight months, contrary to our doctors' recommendations. My wife said at the time, "I don't care what the doctors here say. Where is the evidence that peanut allergies are caused by early exposure to peanuts? [There is none, just a theory.] We all ate Bamba as babies in Israel growing up, and I never even heard of peanut allergies until I moved to the U.S."
