A Sunny Cancer-Fighter

“Laboratory, animal, and epidemiologic evidence suggests that vitamin D may be protective against cancer,” explains Dr. Fuhrman. According to him a lot of research has shown vitamin D to be a potent cancer-fighter. Take a look:
Epidemiologic studies suggest that a higher dietary intake of calcium and vitamin D, and/or sunlight-induced vitamin D synthesis, correlates with lower incidence of cancer, including lymphoma, breast, prostate, and colon cancer.1 In fact, for over 60 years, researchers have observed an inverse association between sun exposure and cancer mortality,2 and those with more sun exposure had fewer cancers.
Speaking of sun exposure—it’s important! Trust the facts. Being a mole-person is not a good idea. Get some sun, and, check out this study in the NewScientist. Sun-drenched populations are more protected against cancer. Andy Coghlan reports:
Sunshine is regularly blamed for causing fatal skin cancers, but it may help save your life if you develop a different cancer. It seems that sunlight has an overall protective effect as it stimulates the body's production of vitamin D, which helps to combat internal cancers, including those of the colon and prostate.

"A little sun exposure is a little better for you than avoiding sunlight," says Richard Setlow of Brookhaven National Laboratory in Upton, New York, who co-led the new work. "Vitamin D doesn't lower the incidence of internal cancers, but it prevents more people dying from them."
Now, in case you’re curious or you forgot. Here Dr. Fuhrman explains just what makes sunlight so special. More reason to go into the light:
Vitamin D is a fat-soluble vitamin that your body makes after exposure to ultraviolet (UV) rays from the sun. Vitamin D functions as a hormone because it sends a message to the intestines to increase the absorption of calcium and phosphorus.
For a long time I used to be a cave-dweller. I’d stay indoors all the time and hardly ever go outside. Not anymore. Now I drag my butt outside fairly often. How about you?

Absolutely! I get out in the sun every chance I get....but not for too long of course. I've never believed that sun caused cancer. There was just something in my little head that told me that couldn't be true!
Thanks for all the great info!

Hey April-

I love the sun. When its real hot it sucks, but, I'd kill for some of that sunny-heat right now--its snowing in Jersey right now! Grrr!

This time of year, the best way to get adequate vitamin D3 is a few sessions in a tanning bed - 10,000 to 15,000IU in a single session. Moderate exposure to UV light in a tanning bed is healthy behavior. Don't sunburn. Don't go tanning everyday. Look better and feel better with a tan.

Hey Jim-

You can't be serious, right? Tanning!

Yes, we are serious uv/sun light makes Vitamin D, a cancer fighter! Avoid sun burns not the sun. And get your moles checked!
