How To Eat Broccoli? See these articles: Broccoli Sprouts and Daily Cruciferous Intake: How To?

Leafy Greens

Leafy greens are the best veggies, says Dr Greger! Are they protective against cancer as well?

Videos by Dr Greger:

(2012) Preventing Breast Cancer by Any Greens Necessary

(2 mins) Transcript. Collards (a cruciferous leafy green) and carrots were identified as the top two veggies in this video.

(2007) Plant-Based Prevention

(4 mins) Transcript. Dr Greger's summary: "Phytonutrients may, in part, account for the benefits of whole plant foods in cancer prevention." Excerpt:

… something so incredibly powerful that it cut skin cancer risk by about 50%—greens. Eating dark green leafy vegetables cuts our risk in half.  Yes, but how many greens did these people have to eat?

Well, here’s the data. These are the people who ate the most greens, and had half the cancer risk—compared to these, who ate the least, averaging only six grams of greens a day. That’s the weight of six paper clips. They must have accidentally eaten the garnish—some sprig of parley next to their steak!

What about the highest tier of greens intake, cutting their squamous cell skin cancer risk in half? Just 31 grams of greens a day; 31 paper clips. That’s the equivalent of just three leaves of spinach. One, two, three leaves a day. Half the risk of this cancer. That’s how powerful greens are. My motto is, eat your greens, every day of your life, until you die.

(2012) Eating Green to Prevent Cancer

(2 mins) Transcript. Dr Greger's summary: "Chlorophyll, the most ubiquitous plant pigment in the world, may protect our DNA against mutation by intercepting carcinogens."

(2016) How to Regenerate Coenzyme Q10 (CoQ10) Naturally

(6 mins) Transcript. Dr Greger's summary: "Chlorophyll in our bloodstream after eating greens may react with wavelengths of sunlight that penetrate through our skin to reactivate the antioxidant Coenzyme Q10 (ubiquinol)."

Sweet Potatoes

Sweet potatoes are underappreciated superfoods! Who says so? WFPB doctors like Dr McDougall. See Tubers. Do they have anti-cancer properties too? Yeah:

(2018) Anti-Cancer Potential of Sweet Potato Proteins

(3 mins) Transcript. Dr Greger's summary: "Sweet potatoes are not just one of the healthiest and cheapest sources of nutrition; the predominant protein is a type of protease inhibitor that may have cancer-fighting properties."

Tomatoes

Through the videos below, Dr Greger highlights a general theme: sometimes, extracting an active compound from a whole plant food doesn't help but the whole plant may! Why? 'Food synergy': various chemicals found in a whole plant may work together to be far more impactful than an extract. Sometimes, extracts may be harmful but a whole plant food may be beneficial.

(2017) Lycopene Supplements vs Prostate Cancer

(5 mins) Transcript. Dr Greger's summary: "High doses of lycopene — the red pigment in tomatoes — were put to the test to see if it could prevent precancerous prostate lesions from turning into full-blown cancer."

(2017) Tomato Sauce vs Prostate Cancer

(7 mins) Transcript. Dr Greger's summary: "What happened when cancer patients were given three quarters of a cup of canned tomato sauce every day for three weeks?"

(2009) Lutein, Lycopene and Selenium Pills

(1 min) Transcript. Lutein is a phytonutrient found in dark leafy greens. Lycopene is found in tomatoes. Selenium is a trace mineral found in nuts and whole grains.

Question: is it meaningful to get these minerals and compounds in pill form instead of having to consume dark leafy greens or tomatoes or nuts & whole grains?

Neither of these three supplements was found to decrease cancer risk. But one of them (lutein) was associated with an increased risk of cancer; so it is harmful.

Dr Greger's closing statement in the video: "Drug companies are never going to find the right combination, but they don't need to, because Mother Nature did it for us."
