Fly Fart-Free: 3 Foods and Drinks to Avoid on a Plane

Want to avoid bloating unwanted germs and gas? Flight attendants say your in-flight diet might be to blame! Here are three things you should skip next time you buckle up.

1. Tap Water (Including Coffee & Tea)

That cup of tea might come with an unwanted side of germs. Flight attendant Sue Fogwell, who flew for 22 years, warns that airplane tap water—used for coffee and tea—comes from notoriously dirty water tanks. In a 2004 EPA study, 13% of sampled planes had coliform bacteria, with some even testing positive for E. coli! If you need a caffeine fix, grab a soda or pre-bought coffee from the terminal.

2. Gas-Inducing Foods

Want to avoid becoming the reason your seatmate keeps turning toward the window? Former flight crew member Josephine Remo advises against eating bloat-causing foods like beans, onions, broccoli, and lentils. Due to changes in cabin pressure, your stomach expands mid-flight, making gas-prone foods even worse. Even carbonated drinks can add to the discomfort. Stick to light, easy-to-digest meals instead.

3. Bloody Marys

Sure, tomato juice tastes better in the sky, but that Bloody Mary could leave you feeling extra puffy. Fogwell warns that the high sodium content leads to bloating and dehydration. If you can’t resist, alternate with plenty of water to keep your body balanced.

For a comfortable, gas-free flight, choose wisely—and maybe save the beans for after landing!

What Not to Eat and Drink at the Airport – And Safer Alternatives

Airport food may be convenient, but some options come with hidden food safety risks. Improper storage, temperature fluctuations, and poor handling can lead to bacterial contamination and foodborne illnesses. 

Here’s what experts say you should avoid—and what to choose instead.

Foods & Drinks to Avoid

  1. Fountain Drinks & Iced Tea
    Fountain machines and iced tea dispensers are difficult to clean, accumulating bacteria like E. coli, Salmonella, and Legionella, which can cause pneumonia. Instead, opt for bottled drinks or freshly brewed coffee or tea, but be cautious of dairy left at room temperature.
  2. Prepackaged Sandwiches & Salads
    These often sit at unsafe temperatures, allowing bacteria to thrive—especially in open refrigeration units. Salads with raw sprouts are particularly risky due to high bacterial contamination. Instead, choose sealed snacks like nuts, granola bars, or dried fruit, or bring your own food.
  3. Fruit Cups
    Once cut, fruit loses its protective skin and can harbor Listeria, E. coli, and Salmonella if not stored properly. Instead, opt for whole, unpeeled fruits like bananas, oranges, or apples.
  4. Unpasteurized Juices & Dairy Products
    Cold-pressed juices and raw dairy products may contain harmful bacteria. Instead, look for sealed, pasteurized products stored at proper temperatures.
  5. Sushi & Raw Seafood
    Maintaining safe temperatures for raw fish at an airport is difficult, increasing the risk of parasites and foodborne illnesses. Instead, opt for hot, fully cooked meals like grilled chicken, shrimp, or pizza.

Final Tips

  • Choose restaurants that look clean and follow hygiene protocols.
  • Wash your hands frequently, as hand sanitizer doesn’t kill norovirus.
  • When in doubt, opt for hot, cooked foods rather than cold or raw options.

Safe eating choices can help you avoid illness and enjoy stress-free travel!
