Ever been on a flight and regretted your snack choice? We've all been there. Whether it's the cramped quarters, the recycled air, or the stress of travel, there are just 15 foods you should never eat on a flight. These are certain snacks that can lead to discomfort, awkward situations, or even some side-eye from your fellow passengers.

When you're thousands of feet in the air, your body reacts differently to certain foods. The pressurized cabin can make digestion tricky, and strong smells can become overwhelming in the confined space. What seemed like a harmless snack on the ground can turn into a source of discomfort or even embarrassment. It's not just about your own experience, either—consideration for those around you is key to a pleasant experience for everyone.

We'll break down why these choices can turn your flight into a not-so-great experience. So, buckle up and get ready to learn how to make your next flight more comfortable and pleasant for everyone involved.

Garlic-Heavy foods

Foods rich in garlic, such as garlic bread or garlic-laden pasta, can cause a strong and lingering odor that permeates the air. In the confined space of an airplane, this can be particularly unpleasant for fellow passengers. Beyond the smell, garlic can also lead to digestive issues like heartburn or upset stomach for some individuals. Given the close quarters and limited ventilation, it's best to avoid consuming garlic-heavy foods before or during a flight to maintain a more pleasant environment for everyone on board.

Onions

Onions, whether raw or cooked, have a potent aroma that can linger long after consumption. This can be off-putting in the tight, enclosed space of an airplane cabin. Additionally, onions can cause digestive discomfort, including gas and bloating, which can be particularly uncomfortable during a flight. The strong smell can also cling to your breath and clothing, making it less than ideal for close interactions with fellow passengers. To maintain a more pleasant atmosphere and avoid potential discomfort, it's advisable to steer clear of onion-laden dishes while flying.

Tuna

Tuna, especially when canned or in a sandwich, has a distinct and strong odor that can quickly fill an airplane cabin. This smell can be overwhelming and unpleasant for other passengers, particularly in such a confined space. Additionally, tuna can sometimes cause digestive issues for those with sensitive stomachs. The combination of its potent aroma and potential for causing discomfort makes tuna a less-than-ideal choice for in-flight consumption. Opting for less aromatic and more easily digestible foods can contribute to a more pleasant travel experience for everyone on board.

Durian

Known for its incredibly strong and often offensive odor, durian is a fruit that can quickly fill an entire space with its scent. In the confined quarters of an airplane, this can be particularly overwhelming and unpleasant for other passengers. The smell is so potent that it has been banned on some public transportation systems in certain countries. Beyond the odor, durian's rich and creamy texture can also be heavy on the stomach, potentially causing digestive discomfort. To maintain a more pleasant environment for everyone, it's best to avoid bringing or consuming durian on a flight.

Broccoli and Cauliflower

These cruciferous vegetables, while nutritious, are known to cause gas and bloating due to their high fiber content and the presence of certain complex sugars. In the pressurized environment of an airplane cabin, these digestive issues can be exacerbated, leading to significant discomfort. Additionally, the smell of cooked broccoli and cauliflower can be quite strong and may not be well-received by fellow passengers. Given the potential for digestive distress and the strong odor, it's advisable to avoid consuming these vegetables before or during a flight to guarantee a more comfortable journey.

Beans

Beans are a great source of protein and fiber, but they are also notorious for causing gas and bloating. This is due to the presence of complex sugars that can be difficult for the body to break down. In the confined and pressurized environment of an airplane cabin, these digestive issues can become even more pronounced, leading to significant discomfort. Additionally, the effects of consuming beans can be unpleasant for fellow passengers who are in close proximity. To avoid potential embarrassment and discomfort, it's best to skip beans before or during a flight.

Chewing Gum

While chewing gum can help with ear pressure changes during takeoff and landing, excessive chewing can lead to swallowing air. This can result in bloating and gas, which can be particularly uncomfortable in the pressurized cabin of an airplane. Additionally, the constant chewing motion can become annoying to nearby passengers. Some gums also contain artificial sweeteners like sorbitol, which can cause digestive issues for some individuals. To avoid these potential problems, it might be better to use other methods for managing ear pressure, such as yawning or swallowing.

Spicy Foods

Spicy foods can cause a range of digestive issues, including heartburn, acid reflux, and stomach upset. In the confined space of an airplane, these symptoms can become particularly uncomfortable. The pressurized cabin can exacerbate these digestive issues, making for an unpleasant flight experience. Additionally, the strong aromas of spicy foods can be overwhelming and potentially irritating to fellow passengers. To avoid these potential problems, it's advisable to steer clear of heavily spiced dishes before and during your flight, opting instead for milder and more easily digestible options.

Fried Foods

Fried foods are often heavy and greasy, making them difficult to digest. This can lead to feelings of sluggishness, bloating, and even nausea, which can be particularly uncomfortable during a flight. The high-fat content in fried foods can also exacerbate symptoms of acid reflux and heartburn. Additionally, the smell of fried foods can linger and be unpleasant for other passengers in the confined space of an airplane cabin. To maintain a more comfortable and pleasant travel experience, it's best to avoid consuming fried foods before or during your flight.

Dairy Products

A variety of dairy products are arranged on a surface. Included are a wedge of Swiss cheese with holes, a glass jar of milk, a glass jar of yogurt, a jar of strawberry flavored yogurt, and various pieces of butter.

Dairy products, such as milk, cheese, and yogurt, can cause digestive issues for those who are lactose intolerant. Symptoms can include bloating, gas, and stomach cramps, which can be particularly uncomfortable in the pressurized environment of an airplane cabin. Even for those who are not lactose intolerant, dairy can sometimes lead to mucus production, which can exacerbate sinus issues and make breathing more difficult. To avoid these potential problems, it might be best to limit or avoid dairy consumption before and during your flight, opting for lactose-free alternatives if necessary.

High-Sugar Snacks

Rapid spikes in blood sugar levels followed by sudden drops can result from consuming high-sugar snacks such as candy bars, pastries, and sugary drinks. This rollercoaster effect on energy levels can be particularly disruptive during a flight, making it harder to rest or stay comfortable. Additionally, high-sugar snacks can contribute to dehydration, which is already a concern in the dry cabin air. To maintain more stable energy levels and stay hydrated, it's advisable to opt for snacks that are lower in sugar and higher in protein and fiber.

Hard-Boiled Eggs

Emitting a strong sulfuric odor, hard-boiled eggs can be unpleasant for fellow passengers in the confined space of an airplane cabin. The smell can linger long after the eggs have been consumed, making it a less-than-ideal choice for in-flight dining. Additionally, eggs can sometimes cause digestive issues for some individuals, leading to discomfort during the flight. To maintain a more pleasant atmosphere and avoid potential digestive distress, it's best to avoid bringing or consuming hard-boiled eggs on a flight, opting for less aromatic and more easily digestible options instead.

Peanut Butter

Posing a significant risk for individuals with peanut allergies, peanut butter can trigger severe allergic reactions in some people even with the slightest exposure to peanut particles. In the confined and shared space of an airplane cabin, this risk is heightened. Additionally, peanut butter can be sticky and messy, making it less convenient to eat during a flight. To guarantee the safety and comfort of all passengers, it's advisable to avoid bringing or consuming peanut butter on a flight, opting for allergy-friendly alternatives like sunflower seed butter or almond butter if necessary.

No to Turbulence in Your Tummy

The foods you choose to eat on a flight can either make your journey more comfortable or turn it into a series of awkward and uncomfortable moments. By being mindful of what you consume, you can avoid unnecessary discomfort and guarantee a smoother, more pleasant trip for yourself and those around you.

Remember, the confined space and pressurized cabin of an airplane amplify the effects of certain foods. Strong odors, potential digestive issues, and the risk of causing discomfort to fellow passengers are all factors to consider when packing your in-flight snacks. Opting for lighter, more neutral options can make a world of difference, allowing you to arrive at your destination feeling better and more refreshed.

Next time you prepare for a flight, think twice about your food choices. A little planning can go a long way in enhancing your travel experience. By avoiding the foods we've discussed, you'll be taking a big step toward a more enjoyable journey. Safe travels and happy snacking!
