Scientists think allergies are largely due to a lack of exposure during the early childhood years. As a result of not being exposed, the body interprets the signals from strange foods as though it is a virus that needs to be attacked.
The good news is that the body can be trained, including peanut allergies, to learn those things aren’t a danger to it.
What about the rise of people who were not allergic and exposed all their lives. Then suddenly get allergies in adulthood?
Have several in the office and years ago I never heard of such a thing
I think those scientist are wrong. I had allergies since childhood to things I lived with, dust, mold, pollen , feathers and ate corn, chocolate, I never ate peanut butter until I was an adult and I am not allergic to it.
This too clean meme is a crock. You inherit the gene.
