just a few thoughts on this thread...
- peanuts are actually legumes, not true nuts
- a peanut allergy may coincide with a tree nut allergy, but there is no proven connection between the two (totally different plant families)
- soy, now rampant in baby formula/infant foods, is a legume
- some studies suggest that exposing infants to soy may in fact sensitize them to peanuts later on
As one who can't eat wheat, and the parent of a child with multiple life-threatening allergies, I've learned to control what I can and avoid the environments where the number of risk factors beyond my control is too great. From a personal point of view, I'm glad to see peanuts return, as we can't eat the pretzels.
