Allergies

Interesting stuff about childhood food allergies over at BoingBoing.

Here's the bit that matters (unless you're desperate to read about the physics of jukebox operations and The Fonz):

"For years, parents have been told to put off introducing their babies to certain foods—things like milk, soy and peanuts—that tend to cause allergic reactions. The idea behind the advice was that, if you gave a baby's immune system a chance to mature before tossing a food trial at it, it might not be so likely to overreact.

But that theory is turning out to be wrong, according to a panel of European and American public health experts from organizations like the FDA and the British National Health Service Trust. There's no evidence that delaying the introduction of potentially allergenic foods does anything to reduce a child's likelihood of developing an allergy, they said. And, in fact, there's some evidence that delaying the foods may actually increase the risk of allergic reaction.

Why? Researchers can only speculate right now, but it might have to do with the fact that you can never completely eliminate environmental exposure to certain foods. Even if you stringently avoid peanuts, you might still come into contact with very, very minute amounts of the allergy-causing nut proteins. As it turns out, it's these small, rare, random exposures that are more likely to set the stage for developing a sensitivity to a particular food, rather than regular consumption.

Once they're ready to eat solids, your baby or toddler is better off being adventurous with new foods." - Maggie Koerth-Baker

My philophsophy is that the doctors don't know everything. I just do what feels right for us even if I disagree with the doc/research at the time. So when it comes to food I just make my decision based of if I think my kid is ready. :)
