A diet rich in fruits and vegetables offers more health benefits than you can count on both hands, including lower blood pressure, reduced risk of heart disease and stroke, cancer prevention, lower risk of obesity and digestive problems, and improved blood sugar levels. Even more, eating the daily recommended doses of fruits and veggies will help you feel full longer and keep your appetite in check.

“There are so many people who rely on supplements and vitamins when we should be able to get most of what we need from our food,” says registered nurse and nutrition advocate Kristin Woodruff. “Make sure you’re getting as many colors on your plate as possible. That is the original multivitamin.”
While the research surrounding the effects of color on health is ongoing, here’s a look at the potential health benefits of tasting the rainbow with some help from Dr. David Heber, author of What Color is your Diet?

Red foods

Health benefits - Contain lycopene , a powerful antioxidant associated with reduced risk of some cancers and protection against heart attacks

Sources - Tomatoes and tomato-based products; watermelon, pink grapefruit, guava, cranberries

Fun fact - Cooked tomato sauces may offer the most health benefits. The heating process allows the body to more readily absorb carotenoids, including lycopene.

Blue/purple foods

Health benefits - Rich in anthocyanin, antioxidants that support a healthy heart and regulate blood pressure

Sources - Eggplant (especially the skin), blueberries, blackberries, prunes, plums, pomegranates

Fun fact - The richer the color, the riper the fruit/veggie. Blueberries have the highest antioxidant activity of all. 

Green foods 

Health benefits - Contain lots of isothiocyanates, which live in the liver and help the body remove carcinogenic compounds; good source of vitamin K (essential for blood clot formation), folic acid, and potassium (helps lower blood pressure)

Sources - Broccoli, cabbage, bok choy, brussels sprouts

Fun fact - The isothiocyanates found in cruciferous vegetables may have cancer-fighting properties, particularly against colon and bladder cancers. 

Yellow/green foods

Health benefits - Rich in lutein, which is especially good for eye health; good source of vitamin C

Sources - Avocado, kiwi, spinach and other leafy greens, pistachios

Fun fact - Pistachios contain lutein in the green skin that surrounds the nut.

Orange/yellow foods

Health benefits - High in vitamin C and beta-carotene (good sources of antioxidants), which convert to vitamin A, a vital  nutrient for vision and immune function as well as skin and bone health

Sources - Carrots, mangos, cantaloupe, winter squash, sweet potatoes, pumpkins, apricots

Fun fact - Beta-carotenes may also help prevent some cancers, particularly lung, esophagus and stomach.

White/green foods

Health benefits - Rich in flavonoids, powerful antioxidants that help the body combat free radicals

Sources - Garlic, onions, endives, chives, celery, pears

Fun fact - A recent study found that increasing your intake of white fruits (those with white flesh) may lower your risk of stroke.
