"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

See  https://en.wikipedia.org/wiki/Food_intolerance

As usual Wikipedia is your friend.

See the links at the bottom for Lactose and Gluten tolerance problems.  These are fairly common.
