The Rainbow of Food: How Phytonutrients Support a Cancer Protective Diet

Phytonutrients: Eat the rainbow

WHAT ARE PHYTONUTRIENTS?

Phytonutrients are compounds produced by plants to help protect them from environmental damage or predators. Some phytonutrients have been found to have cancer-protective properties, and many are anti-inflammatory. We recommend you get phytonutrients by eating whole foods to ensure you get all the phytonutrients, plus the vitamins, minerals, and fiber whole foods also provide to support a well-balanced diet. 

THE RAINBOW

RED 

The phytonutrients that give food theirREDcolor include anthocyanidins, carotenoids, flavones, flavanols, luteolin, lycopene, and quercetin. These compounds vary in abundance between different foods. These phytonutrients help reduce inflammation in our bodies and protect us from free radicals that can damage DNA, increasing a person’s risk of developing chronic disease.

To learn more aboutREDfoods, check out some of our favorites: beets, radishes, tomatoes, sweet red peppers, rhubarb, red onions, red potatoes, apples/applesauce, grapefruit, pomegranate, cranberries, watermelon, strawberries, cherries, plums, raspberries, red grapes, and kidney beans.

We have many recipes that showcaseREDcolors; here, we highlight a few:

ORANGE

The phytonutrients that provide theORANGE color of foods include beta-carotene, bioflavonoids, carotenoids, and curcuminoids, to name a few. These compounds vary in abundance between different foods. These phytonutrients help reduce inflammation in our bodies and support eye and skin health.

To learn more about ORANGE foods, check out some of our favorites: acorn squash, winter squash, sweet potato, pumpkins, carrots, bell peppers, oranges, persimmons, mango, papaya, apricots, tangerines, dried fruit, nectarine, cantaloupe.

GREEN

There are so many reasons to celebrate GREEN today and every day. One well-studied phytonutrient that comes from the cruciferous vegetable family is indole-3 carbinol. Animal and cell studies have found indole-3 carbinol to inhibit progression in several cancers by protecting our healthy cells from DNA damage, antiviral and antibacterial effects, and anti-inflammatory effects.

GREEN plants often have other colors mixed in with them, providing even more phytonutrients! Cruciferous vegetables include arugula, Bok choy, broccoli, cabbage, kale, and Swiss chard.

To learn more about GREEN foods, check out some of our favorites: brassicas (i.e.,broccoli, brussels sprouts, cabbage, kale, collard greens, kohlrabi, arugula, chard), spinach, watercress, celery, peas, cucumbers, artichokes, green peas/snow peas, lettuce, asparagus, okra, olives/olive oil, lime, rosemary, basil, parsley, cilantro, thyme, green tea, and Matcha.
