Plan ahead and pack snacks
Being hungry and left wandering the airport in search of food is a surefire way to end up scarfing down sugary or high-fat foods. The problem is packaged, processed snack foods like chips, candy, baked goods and chocolate bars won’t fill you up for long. They’ll actually end up intensifying your cravings for carbs and sugars throughout your travels, says registered dietitian Sarah Remmer. Instead, pack healthy snacks such as high-fiber granola bars, fruit, nuts and seeds, or whole-wheat crackers and peanut butter, so you’re never without a healthy option.
