7 foods you should never eat on a plane

Bringing your own food on the plane makes perfect sense, both for your taste buds and your wallet.

But whether you're packing your own snacks or buying a gate-side meal to-go, you should avoid these seven foods — for your sake and those around you.

Food You Can't Finish

If you decide that a long flight is the time to tuck in to a special treat, more power to you. Just make sure you have time to finish it — or that you're okay with throwing it away before you land. In most countries, you'll have to declare any food (even packaged items) before entering, and something that you've opened up might not make it in.

Fresh fruits and vegetables usually won't be allowed in, either, due to agricultural concerns. (The U.S. Customs and Border Control Agency offers this helpful guide, but other countries will have different rules.)

Instant Soups

Some people will tell you to bring a cup of noodles or other instant soup aboard a flight and ask the flight attendant for boiling water during meal service. Although a mug of hot soup may sound enticing, it’s a bad idea to keep a cup of scalding liquid near your lap when turbulence could strike at any second. Plus, many prepackaged ramen cups have close to half of your daily recommendation of sodium, which certainly won't help you fight jet bloat.

Noisy Foods

Crunch… crunch… crunch… Put down the chips or raw vegetables — your seatmate does not want to listen to you chew. Crunchy foods can sound louder than a jet engine when you're basically chewing right in your seatmate's ear.

Remember that the person next to you has nowhere to go, so save the noisy foods for when you land.
