If you're doing a lot of traveling over this week between Christmas and New Year's, you might want to give what you put in your stomach some second thought. According to Healthday, traveling across time zones can mess with your natural body rhythms, and your stomach can get jet lag too. Eating when you're supposed to be sleeping or sleeping when you're supposed to be eating can upset your digestive system. Combine that with heavy holiday meals, and you've got a recipe for digestive disaster.

If you're traveling, try to eat regular, light meals and avoid things like alcohol and carbonated beverages. If you give it some time, your stomach will eventually catch up with the rest of you!
