Plan ahead: "Choose foods to take in the car, eat before arriving at the airport and consider the options available upon arrival at the destination," Newton said in a UAB news release this week.
Keep it on ice: Put a cooler in the car and pack it with such healthy treats as fruit, yogurt, water, cut-up vegetables and sandwiches on whole-grain bread.
Eat this, not that: Make the best food choices you can when you're on the road. At convenience stores, go for yogurt, fresh fruit, fruit cups or nuts (which are good in moderation.) At burger joints, the most simply prepared items are the healthiest choices, according to Newton. She suggests a plain hamburger with lettuce and tomatoes or a grilled chicken sandwich with lettuce and tomatoes. You can also hold the mayo and dressing and choose kid-size portions.
Don't eat out all the time: If possible, rent a hotel room or vacation home with a refrigerator and stock it with good food. "It can be easier to eat healthful meals when cooking yourself," Newton said.
Search the web: Look online for restaurants in the area you're visiting. Review the menus in advance and decide what to eat before you go.
Drink lots of water: People often mistake dehydration for hunger, according to Newton.
