During cold and flu season we all make efforts to avoid germs, whether it's using a paper towel to open a door or covering your mouth when you cough. Here's one common way to get sick without realizing it: eating a banana. If you peel a banana and eat the fruit inside, you risk cross-contaminating yourself with germs. The outside of the banana has been touched countless time by lots of people: farmers, packers, store employees and countless shoppers who've pawed their way through it. Best to peel the banana and eat it with utensils to stay healthy.
