Preparing for a flight is not only about what you pack into your bags but also what goes inside your stomach. Luxurious seating and business-class hospitality cannot compensate for a poorly planned meal before a flight. Changes in air pressure and density on board a flight cause a shift in meal requirements before and during one’s air journey. This article provides a list of foods that one should avoid before boarding a flight: Apples The proverb “an apple a day keeps the doctor away” cannot be more accurate, considering the abundance of antioxidants and vitamin C in apples. However, the fruit is extremely high in fiber content, which may cause problems with digestion and lead to bloating. Such issues can have a more severe impact while one is on board a flight. Hence, it is best to opt for fruits like oranges, berries, and papayas, which are easier to digest, before flight journeys. Cruciferous vegetables Cruciferous vegetables like broccoli, cauliflower, cabbage, and Brussels sprouts are high in vital nutrients; however, they can be heavy on the stomach and trigger digestion issues. They are also rich in a sugar called raffinose, which often causes bloating. It helps to avoid cruciferous vegetables before a flight, swapping them with lighter foods like white rice, fermented foods, and instant oats.
