Carbonated Beverages: Soda and other fizzy drinks can cause bloating and gas due to the high-altitude pressure changes, leading to discomfort.
Alcohol: It might be tempting to have a glass of wine or a beer to relax, but alcohol can dehydrate you faster, especially in the dry cabin air, and can also affect your sleep quality on long flights.
Salty Snacks: Foods high in salt, like chips or pretzels, can increase dehydration and lead to swelling and bloating.
Beans and Legumes: While healthy, beans and legumes can cause gastrointestinal discomfort and bloating due to their high fiber content, which can be exacerbated in the pressurized cabin.
Cruciferous Vegetables: Broccoli, cauliflower, and cabbage are known to cause gas and bloating. It’s best to avoid these before and during flights to prevent discomfort.
Garlic and Onions: These can cause bad breath and may also contribute to an upset stomach, which isn't ideal when you're confined to a small space.
Spicy Foods: While delicious, spicy foods can upset your stomach, leading to acid reflux and heartburn, which are particularly uncomfortable during a flight.
Heavy Meals: Eating large, heavy meals can make you feel lethargic and uncomfortable. Digestion is slower in the pressurized environment of a plane, so it's better to eat light.
Caffeinated Beverages: Coffee and tea can lead to dehydration and may increase your need to use the restroom, which is not always convenient on a crowded flight.
Dairy Products: For those who are lactose intolerant or sensitive, consuming dairy before or during a flight can lead to gastrointestinal distress.
