Traveling is at its height during the holidays—up by 23%, according to the U.S. Department of Transportation—as are the calories you presumably consumed before, during, and after each special occasion. And with major holidays studded throughout the calendar year—summer barbecues, big winter dinners, and the occasional springtime beer-and-potato binge—that means many of us are shlepping more or less non-stop via planes, trains, and automobiles.

If you should find yourself at an airport, don't let it be your excuse to continue letting your diet spiral out of control. Instead, get back on track before you touch down at your final destination.

To help you do just that, we worked with Molly Kimball, C.S.S.D., R.D., a dietitian at Ochsner's Elmwood Fitness Center in New Orleans, to narrow down the overwhelming selection of foods readily available within most airports to the 12 healthiest options you can purchase at magazine shops, delis, and kiosks. From nuts to smoothies, the picks in this roundup contain minimal sugar and refined carbohydrates, while being rich in protein and healthy fats, which will ensure sustained energy before boarding that flight. 

Next time you roam the terminals in search for a healthy snack—holiday season or not—skip the fast food chains and consult this list instead.
