But what is healthy? You can't go wrong with anything that has bright, vibrant colors—think fruits and vegetables, not boxes of processed junk food.

Red
Rosy-hued fruits and vegetables offer a payload of an important antioxidant called lycopene, which is associated with health benefits like protecting the skin from sun damage and decreasing the risk of heart disease and certain forms of cancer.

Lycopene-rich foods also have been shown to decrease symptoms of wheezing, asthma and shortness of breath in people when they exercise.

Tomato - Canned and cooked tomatoes have been shown to contain more lycopene than fresh, so go crazy with the ketchup, salsa and marinara sauce.
Red Bell Pepper - The reds pack twice the vitamin C and nine times as much vitamin A as their green relatives. They've been shown to aid in the fight against everything from asthma to cancer to cataracts.
Guava - Guava is packed with vitamins A and C. It also contains heart-healthy omega-3 fatty acids and belly-filling fiber.
Watermelon - This summertime favorite is also a big provider of vitamins A and C, which help to neutralize cancer-causing free radicals.
Pink Grapefruit - This contains one of the highest concentrations of antioxidants in the produce aisle.

Orange
The vaunted vitamin C monster has critical phytonutrients known to lower blood pressure and contain strong anti-inflammatory properties. Juice is fine, but the real fruit is even better.

The secret, though, is that the orange's most powerful healing properties are found in the peel. Use a zester to grate the peel over bowls of yogurt or salads or directly into smoothies.

Sweet Potato - The best part about sweet potatoes, outside of the beta-carotene, is that they're loaded with fiber. That means they have a gentler effect on blood sugar levels than regular potatoes.
Carrot - The snack of choice for Bugs Bunny happens to be the richest carotene source of all. Baby carrots are perfect plain for dipping or snacking, of course, but also try shredding carrots into a salad or marinara for a bit of natural sweetness.
Cantaloupe - Sliced cantaloupe and yogurt make a great breakfast, or combine the two in a food processor with a touch of honey and lemon and puree into a great low-cal dessert.

Yellow
Yellow foods are close relatives to orange foods, and, likewise, they are rich in carotenoids. Studies show yellow foods can decrease the likelihood for such diseases as lung cancer and arthritis, but since youngsters have more important things to worry about, you're better off selling yellow foods on their superpowers—jumping higher and playing harder!

Research shows that yellow foods help decrease inflammation in the joints, ensuring a springy step in kids for years to come. Studies also show they may improve the functioning of the respiratory system, making beating their classmates in dodgeball and relay races just that much easier.

Yellow Bell Pepper - Yellow bells are vitamin C treasure troves, providing two and a half times the amount you'd get from an orange. Their sweet, mellow flavor is perfect for kids.
Pineapple - Skewer chunks and cook on a hot grill for a killer dessert.
Corn - This king of the summer barbecue is loaded with thiamin, which plays a central role in energy production and cognitive function. Boost their brains and their energy levels by carefully removing the kernels from the cob with a kitchen knife and sautéing with a bit of olive oil.
Banana - Bananas are loaded with potassium, which will help your kids grow strong, durable bones. Here's a shopping tip: Not all bananas are grown equal. Search for those with a deeper gold to their edible flesh.
Yellow Squash - With huge doses of fiber, manganese, magnesium and folate, summer squash proves to be a serious nutritional player.
