Yes, that means skipping the airport’s fast food restaurants conveniently situated between security and your gate. French fries and chips are loaded with fat and sodium, which your body can struggle to process at high altitudes, and that can lead to fluid retention and bloating.

No chips, no burgers. As well as being another high-fat, high-sodium deal, burgers – and red meat in general – can be difficult to digest. That can result in nausea and cramping and a general blah feeling that’s probably not how you want to start your holiday.

A surprise addition, maybe, but hear us out. Apples are a great source of fibre – which is normally fantastic news – but they can be difficult to digest. A build-up of gas and bloating isn’t fun at the best of times, but stuck on a 12-hour flight? Torture.

Baked, broad, borlotti… Whatever your bean of choice, it’s probably best to steer clear until you hit the tarmac. Like apples, they’re heavy on the fibre and can cause uncomfortable cramping in the air.

As well as causing gas, downing a couple of colas or lemon soda can also kickstart some pretty unpleasant heartburn. It’s easy to become dehydrated up in the air, though, so stick to water – and plenty of it.

Spicy food in general can lead to stomach discomfort and, believe it or not, bladder irritation, so giving chilli and peppers a wide berth is probably the safest bet.

Bet you thought you’d get away with this one. Sorry foodies, but saying no to those cute-as mini G&Ts or a swig of whisky is the easiest way to get through a flight. Alcohol can be incredibly dehydrating, and if you start boozing at the very start of your flight, your hangover will be kicking in just as you land. Once again, water is your on-board best friend.

Double whammy of bad news, but coffee’s out too. Caffeine is another big offender when it comes to dehydration, and while a well-timed coffee can be known to heal a headache, stick to green tea or peppermint tea during the flight.

Cruciferous vegetables like broccoli, cauliflower and Brussels sprouts produce gas in your stomach and can cause bloating. Try to avoid eating these prior to boarding and if you see them served in in-flight meals, do not take too much.

We would never normally say this, but let’s temporarily leave garlic out of any cooking before you take to the skies; your fellow passengers will thank you for it!
