The saying goes: “Beans, beans, they’re good for your heart. The more you eat, the more you…” (well, you know the rest).

This is especially true when you’re flying. According to Dr. Oz, beans, lentils and cruciferous vegetables (broccoli, cauliflower, Brussels sprouts, etc.) are the foods you’ll want to avoid before air travel.

“The foods you eat can make you miserable or make you very happy,” he tells Rachael. “Because you’re flying at a high altitude and your body’s not completely pressurized, your intestines sort of swell. If you have lentils, beans, any cruciferous vegetables or a gassy beer, you start to bloat and you can’t hold it in.”

Dr. Oz suggests staying hydrated with water or herbal tea and says it’s important to pack a snack (nuts are a great option!) to hold you over while flying.

So be courteous to yourself and your fellow passengers. Follow the doc’s advice.
