Healthy Airport Food: What to Grab

Short answer: The healthiest airport food is usually the simplest: water, fruit, nuts, yogurt, hummus with vegetables, or a salad or bowl with a protein, picked over sugary drinks and sweets. [S06] [S10] Snacks that combine protein and fiber tend to keep you full longer, and a quick look at the label for sodium and added sugar makes it easy to compare two options. [S10] [S07] You can also bring your own: solid foods can go through security in your carry-on, while liquid or gel foods over 3.4 ounces can't. [S01]

What to look for at the airport

Most terminals have the same mix of coffee counters, grab-and-go fridges, newsstands, fast food and sit-down restaurants. The useful question isn't which spot is "healthy." It's which item at that spot gives you some protein, fiber and water without a lot of added sugar or salt.

Harvard's Nutrition Source notes that snacks with protein, fiber and whole grains, such as nuts, yogurt and popcorn, tend to be more satisfying. [S10] It suggests aiming for roughly 150 to 250 calories for a snack, and checking the serving size on packaged foods, since one bag can hold more than one serving. [S10]

Good picks you can find in most terminals:

• Grab-and-go fridge: yogurt, cottage cheese, cheese, hummus with vegetable sticks, cut fruit, or a salad with a protein. [S10]
• Newsstand: unsalted nuts, a whole apple or banana, whole grain crackers, roasted chickpeas, popcorn. [S10] [S08]
• Coffee counter: plain coffee or tea, plus fruit or yogurt if you need food. [S06] [S10]
• Restaurant or food court: a bowl or salad with vegetables and a protein, with sauce or dressing on the side. [S08]

If your options are limited, a simple pairing works well: a piece of fruit plus a small bag of nuts, or yogurt plus an apple. For more everyday ideas, see our eating well while traveling guide.

How to read a label in 30 seconds

Many airport foods are packaged, which makes them easier to compare. The FDA's rule of thumb for the percent Daily Value (%DV) on the Nutrition Facts label is simple: 5% DV or less of a nutrient is low, and 20% DV or more is high. [S07]

Use it like this:

• Sodium: aim for a lower %DV. The Daily Value for sodium is less than 2,300 milligrams a day, so one salty snack can use up a large share. [S08]
• Added sugars: aim for a lower %DV. The Daily Value is 50 grams, and the biggest sources in American diets are sugary drinks and sweets. [S09]
• Fiber: a higher %DV is a plus.
• Protein: the label usually doesn't list a %DV for protein, so look at the grams instead. [S07]

You don't need to add anything up. Comparing two packages side by side, such as two kinds of crackers or two yogurts, is usually enough to pick the better one.

Drinks: start with water

Travel days can be long and dry, and it's easy to go hours without drinking much. The CDC points out that water has no calories, recommends choosing it over sugary drinks, and suggests carrying a reusable water bottle. [S06] Because liquids over 3.4 ounces can't go through the checkpoint in a carry-on, the simplest approach is to fill your bottle after screening. [S01] [S02] Our guide to hydration habits has more ideas for drinking enough on the road.

Plain coffee and tea are low-calorie choices. [S06] The drinks that add up quickly are the ones the CDC lists as sugary: regular soda, sports drinks, energy drinks and sweetened coffee drinks. [S06] If you have a drink at the airport bar, the CDC's advice is that if you choose to drink alcohol, do so in moderation. [S06]

Caffeine deserves a thought too, especially before a night flight. The FDA says up to 400 milligrams a day, about two to three 12-ounce cups of coffee, isn't generally linked to harmful effects in healthy adults, but sensitivity varies from person to person. [S13] Our guide to caffeine and sleep explains why timing matters.

Sit-down meals and food courts

A restaurant meal before a flight can still be a good one. A few FDA tips for eating out apply well at the airport:

• Ask for nutrition information before you order. [S08]
• Ask for sauces and dressings on the side, so you control how much you use. [S08]
• Choose unsalted versions of snacks like nuts when you can. [S08]

Beyond that, build the plate around vegetables and a protein, and treat fries or a pastry as an extra rather than the meal. A bowl, salad, sandwich on whole grain bread or a breakfast with eggs and fruit are all easy to find in most terminals.

What you can pack through security

Packing food from home gives you more control and can save money. If you're planning food costs for a trip, our Travel Budget Worksheet has room for them.

TSA's rules for food are straightforward:

• Solid foods are allowed in carry-on and checked bags. [S01]
• Liquid or gel foods over 3.4 ounces aren't allowed in a carry-on and should go in a checked bag. [S01]
• Items that count as liquids or gels must fit TSA's 3.4-ounce (100 milliliter) limit and go in one quart-sized bag. [S02]
• Peanut butter and yogurt count as liquids or gels, so only 3.4 ounces or less can go in your carry-on. [S04] [S05]
• Officers may ask you to separate items like foods and powders from your bag for screening. [S01]

One exception surprises people. If you're flying from Hawaii, Puerto Rico or the U.S. Virgin Islands to the mainland, you can't take most fresh fruits and vegetables with you. [S03]

Easy foods to pack include whole fruit, nuts, whole grain crackers, roasted chickpeas, cheese and vegetable sticks. [S10] Think about how long the day will be. Perishable food shouldn't sit out for more than 2 hours, or 1 hour if it's above 90°F, and bacteria grow fastest between 40°F and 140°F. [S11] On a long trip, foods that don't need chilling are the safer choice.

Food allergies on the go

If you have a food allergy, grab-and-go labels help. The FDA lists nine major food allergens, including sesame, and labels must name them either in the ingredient list or in a "Contains" statement. [S12] Freshly made items at airport counters may not carry a full label, so ask staff about ingredients before you buy. The FDA notes that a reaction can become life-threatening quickly and may need emergency treatment such as epinephrine, so if you've been told to carry medicine, keep it with you rather than in a checked bag. Our guide to packing medications covers how to do that.

Make it a habit, not a perfect meal

One airport meal won't make or break your health. What helps more is having a default you return to every trip: water first, a protein-and-fiber snack in your bag, and a quick label check when you're choosing between two options.
