Eat the Rainbow for Disease Prevention

Eating the rainbow has been a popular health concept since the early 2000s when a group of doctors wrote the book, “How to Prevent and Treat Cancer with Natural Medicine.” Moreover, the doctors advocated a diet rich in plant-based, colorful foods that they called “The Rainbow Diet.” Additionally, their plan has grown in popularity through the years as research has confirmed that eating a variety of colorful produce in place of other, less-healthy foods can prevent the onset of all sorts of diseases and ailments, including type 2 diabetes, heart disease, hypertension and certain types of cancer. The colors of the product indicate which phytonutrients the plant contains.

Red Produce

Red produce like raspberries, red bell peppers, and cherries get their red coloring from a plant pigment called anthocyanin or the carotenoid hydrocarbon lycopene.

Moreover, anthocyanins in red fruits and vegetables have been shown to fight off free radicals and may protect the body against inflammation, cancer, and certain viruses. Similarly, lycopene is an incredibly powerful antioxidant that’s healthy for your brain, heart, and eyes. Furthermore, a 2016 study published in the American Journal of Clinical Nutrition found a correlation between foods high in lycopene ― particularly tomato sauce ― and a reduced risk of prostate cancer in men. Further research has found that lycopene-rich foods help fight breast cancer and renal cell carcinoma.

Furthermore, red fruits and vegetables are excellent for fighting off diseases and bolstering the body’s immune system.

Orange and Yellow Produce

Orange and yellow produce is generally high in vitamin C and carotenoids. Moreover, carotenoids are phytonutrients that act as antioxidants in the body. Moreover, they are excellent for shutting down free radicals, strengthening the immune system and bolstering the body’s immune system. Also, in an article titled “Orange Is the New Pink,” registered dietician Susan Levin wrote, “Women who consume the most orange vegetables, which are rich in carotenoids, lower their risk of breast cancer by 19 percent.”

Furthermore, our bodies do not produce carotenoids on their own. Additionally, we have to consume them in the diet. They’re fat-soluble so to be used by the body, we must eat our carotenoid-rich foods along with fat. Moreover, that means dipping those baby carrots into some creamy Mediterranean-style hummus or eating orange segments with a bit of real whipped cream.

Blue, Purple, and Black Produce

Blue, purple and black produce like blueberries, purple cauliflower, and black grapes also get their deep coloring from anthocyanins. Aside from the benefits mentioned above of anthocyanins, these powerful flavonoids are also fantastic for brain health. Moreover, a study in The American Journal of Alzheimer’s Disease & Other Dementias found that older adults who ate more anthocyanin-rich berries had a significant reduction in cognitive decline.

Green Produce

Green fruits and vegetables contain potent pigment chlorophyll. Chlorophyll is a particularly wonderful phytonutrient. Moreover, it helps to purify your liver, build up strong red blood cells, improve blood sugar levels and deodorize the body. Chlorophyll can also help reduce hunger and relieve pain from inflammation.

Cruciferous produce in the green category like Brussels sprouts, broccoli, green cabbage, and bok choy also contains indoles. Moreover, indoles are compounds that may help the body fight off cancer cells. Moreover, a clinical trial with a small group of women who had early-stage cervical cancer showed promising results. For 12 weeks, more than half of the women treated with indoles had complete regression of their cancer symptoms while none of the women who were given a placebo had any regression. Furthermore, it was a small study, with only around 30 participants, but it’s encouraging, and it shows just how powerful and beneficial green vegetables are.

White and Brown Produce

The brighter-colored fruits and vegetables often get all of the attention when we consider their health benefits. Moreover, we know that white and brown are not the colors of the rainbow. Just humor us here. We’re including them in our food rainbow.

Ever heard the myth that iceberg lettuce has no nutritional value? Yeah, that’s not true at all. Moreover, researchers have found that iceberg lettuce contains a compound called apigenin. Celery also contains it. Moreover, it has been found that apigenin can prevent cancer growth and possibly kill cancer cells. Apigenin has also been shown to improve neurological functioning.

Furthermore, other white and brown fruits and vegetables are incredibly healthy for you too. Moreover, many of the items in this pale produce category contain anthoxanthin, which is an antioxidant pigment. Anthoxanthins are hardcore cancer fighters. Moreover, they’ve also been shown to reduce the risk of stroke and decrease inflammation.

Many varieties of white and brown fruits and vegetables also contain quercetin and allicin. Moreover, these phytonutrients can help prevent allergies, fight off viruses and bacterial infections and reduce blood cholesterol.

White and brown produce is also often high in potassium.
