When I was young it was extremely rare to be allergic to peanuts or most other foods. Today, nobody eats "real" food. It's artificial sweeteners,peanut butter and other "foods" made of soy and partially hydrogenated corn syrup. What's the last thing you bought where the main ingredient was actually what you thought you were buying? Get away from artificial ingredients and the problem will start to diminish. Unfortunately, it will take years to get back to where we were.

Now when you eat something natural the body reacts like it is a foreign substance that needs to be dealt with.
