Eating Green to Prevent Cancer

Why do people who eat more plants get less cancer? The largest prospective study of diet and cancer in history, for example, found that vegetarians had lower levels of all cancers combined. This could be due to what they eat less of:

There are also components of plant foods they are getting more of that can help eliminate excess estrogen; extinguish free radicals; and boost our antioxidant, detoxification, and DNA repair enzymes. What we do eat may be as important as what we don’t eat.

The healthiest food is dark green leafy vegetables, which we should ideally eat every day. Greens can improve our eyesight, immune function, athletic performance, and even our physical appearance. The green pigment itself—chlorophyll—may even intercept carcinogens. See my NutritionFacts.org video pick above.

For more on protective compounds in plants, check out my video Phytochemicals: The Nutrition Facts Missing From the Label. Green pigments are just one sliver of the rainbow though. There are benefits to the yellow onesorange onesred ones, and blue ones. Sounds like a Dr. Seuss book!

In health,

Well, now as I eat my spinach and kale everyday I will be imagining them grabbing my carcinogens and booting them out. Thanks for the great article.

Just as I get a hankering for green olives, I must have greens every day. I'll have huge salads with mixed greens, romaine, baby spinach, fresh green cabbage, sprouts and anything fresh I have that will add to the salad. Other days I'll saute dandelion greens when they are in season, add a little olive oil and lemon juice. Another addiction for me is collard greens and red or green swiss chard. With all my greens that require cooking, I use the saute method rather than boiling. Greens of any kind along with an organic jewel yam baked to sticky sweet perfection--that's heaven to me.
