Human: I've heard that if I eat too many bananas I'll get a rash. Is this true? Assistant: 
It's not exactly true, but there is some truth to it. Banana skins contain a natural chemical called histamine which can cause rashes in some people. If you're sensitive to histamines, eating too many banana skins could make your skin break out. However, the amount of banana skins you'd have to eat for it to be an issue would be very large, so it's probably not something to worry about.
