4. Harambe Market (Disney's Animal Kingdom, Harambe)

The newest eatery at Disney's Animal Kingdom is a street-food market that has plenty of good-for-you options. The market in the Africa section of the park features four walk-up windows — Kitamu Grill has all-natural grilled chicken skewers with roasted broccoli and tomato salad; Boerewors Sausages also has a grilled vegetable stack with herb pesto and chickpea salad; Chef Mwanga's has spice-rubbed Karubi ribs with green papaya-carrot slaw and chickpea, cucumber and tomato salad; and Wanjohi Refreshments has drinks to wash it all down. 

5. The World Showcase (Epcot)

Epcot's World Showcase has a nearly endless assortment of food choices, and even if it's not time for the Food and Wine or Flower and Garden festivals (where small-portioned dishes abound), you can still make a meal out of sampling the goods from the various countries. Try starting in Mexico with some fresh guacamole at La Cantina de San Angel, then have a ham and apple sandwich on multigrain bread at Norway's Kringla Bakeri Og Kafe. Have a hot beverage at Joy of Tea in China, then maybe try some traditional cold potato salad with eggs at Germany's Sommerfest.

Have some gelato in a cup from the Italian Gelato Kiosk and don't feel too guilty about it, since most varieties of gelato have fewer calories than ice cream. If you're still hungry, there are sweet potato tortilla chips to be had at Liberty Inn at the American Adventure; sushi and edamame at Japan's Kabuki Cafe; a vegetable platter with falafel, tangerine couscous salad, hummus, tabouleh, lentil salad and marinated olives at Morocco's Tangerine Cafe; a cheese plate at the Boulangerie Patisserie in France; and whole fresh fruit at the Yorkshire County Fish Shop in the United Kingdom. Canada is the only country without a counter-service option, but popcorn can be found at a cart near the entrance to Le Cellier.

6. Think outside the parks

If you're willing to leave the parks for a meal, you'll find lots more choices at the resorts. For breakfast, you can have a make-your-own omelet or make-your-own yogurt parfait at resorts such as Art of Animation, which also has create-your-own salad and pasta options for later in the day. Other interesting resort options include the steakhouse salad with mustard vinaigrette at the Contemporary's Contempo Cafe, Hawaiian flatbread pizza and fish tacos at Capt. Cook's at the Polynesian and the grand turkey sandwich on sunflower bread at the Grand Floridian's Gasparilla Island Grill (which is open 24 hours).  

There are enough low-calorie and healthy treats at the parks that it should be easy to skip the high-fat burgers and other gut-busting meals. So with some planning and menu consideration, you can stay on the healthy-eating track, even when you're on vacation!
