Bananas can indeed cause migraines. But when we put people on an anti-migraine diet, and tell them to stay away from bananas, it's not the banana, it's the peel. If you can make sure there is no peel stuck to the banana, you won't get migraines from them. Just shave the outside of the banana. The peel contains the same chemical found in red wine and chocolate, which produces migraines in some people. -- Robert B. Daroff, MD, president, American Headache Society, neurologist.
