In the 80’s as a NICU nurse, studies came out that showed people with peanut allergies had a cross sensitivity to soy, and the peanut allergies were probably developing because of early exposure soy. That information seems to have gotten buried as they’ve genetically modified our food. I avoid products with soy, and I hear birds won’t eat the genetically modified soy either.
It turned out to be a tainted study. But we also avoid soy. And try to keep low on modified foods, like corn.
