Are you one of those people that like to grab a meal in the airport terminal right before your flight? From burgers, chicken wings, and smoothies to a good ole’ cup of joe to keep you awake for the next few hours—the choices are endless. But a lot of these edible options are not your stomachs best friend, especially when you’re about to fly.

Many foods, in fact, will cause your tummy feel bloated and gassy, making your whole trip very uncomfortable (and even harder for you to fall asleep). So to make your long flight a bit more enjoyable, here are a few foods and drinks to avoid. Your digestive system will thank you ;).

Alcohol

It can be refreshing to drinking a glass of wine or a cup of beer (or maybe some brandy) with your in-flight meal. But the issue with alcohol is it causes body dehydration. And since you already lose one liter of water while flying, drinking alcohol will add on to the dehydration. If you really cannot go without a glass of red or white, then make sure you at least drink twice the amount of water as you do alcohol.

“Cross Shaped” Vegetables

These veggies are high in carbohydrates that your small intestine cannot break down, however, once they reach your large intestine, the bacteria that lives there goes to work, causing your tummy to blow up. Of course, these vegetables are healthy for you (can’t argue there!), but not when you’re flying sky high with high cabin pressures.

It’s best to stay away from them before and during your flight in order to avoid cramps and gas. It will also help you from feeling embarrassed while you’re up in the air since you won’t need to visit the toilet as often to let out the built up gas.

Carbonated Drinks

Carbonated drinks in a high pressured cabin won’t make your stomach feel any better. The bubbles will make your gastro-intestinal tract gassy, and running to the restroom to release those air bubbles every thirty minutes or so is not ideal either.

Caffeine

Caffeine is a diuretic, which will make you want to head to the toilet more often than you want to. This will mess with your sleep, and can give you unwanted jitters. Plus, it causes additional dehydration that you’ll want to avoid while flying (just like alcohol).

Give your tummy a break! If anything, try fasting a bit before your flight. According to research, this can actually help you with jet lag as well.
