Markedly Higher Vitamin D Intake Needed to Reduce Cancer Risk

[Richard D]

Researchers at the University of California, San Diego School of Medicine and Creighton University School of Medicine in Omaha have reported that markedly higher intake of vitamin D is needed to reach blood levels that can prevent or markedly cut the incidence of breast cancer and several other major diseases than had been originally thought.

The findings are published February 21 in the journal Anticancer Research.
While these levels are higher than traditional intakes, they are largely in a range deemed safe for daily use in a December 2010 report from the National Academy of Sciences Institute of Medicine.
"We found that daily intakes of vitamin D by adults in the range of 4000-8000 IU are needed to maintain blood levels of vitamin D metabolites in the range needed to reduce by about half the risk of several diseases -- breast cancer, colon cancer, multiple sclerosis, and type 1 diabetes," said Cedric Garland, DrPH, professor of family and preventive medicine at UC San Diego Moores Cancer Center. "I was surprised to find that the intakes required to maintain vitamin D status for disease prevention were so high -- much higher than the minimal intake of vitamin D of 400 IU/day that was needed to defeat rickets in the 20th century."

1. Word of advice

A lot of Vit C uses a sodium abscorbate base which your stomach cannot handle in large quantities. A few supplier use calcium abscorbate which is generally ok.

2. Has anyone ever done a study of primitive people in their natural habitats

to see what their vitamin levels are? Instead of guessing by using people in our FUBYAR societies?
You know, do some research on our roots for a base level to reference by.

5. I believe so

It was years ago when I saw it though. Of course the source of their Vit D was solar exposure, which, in our northern latitude sun phobic society, very few of us get enough of to make much Vitamin D.

3. So the ultimate "cure" for cancer is to use your immune system to prevent

it altogether, who would have thought.

4. What a horribly naive and terribly judgmental thing to say.

Are you basically blaming every cancer victim for not having an adequate immune system?

Yes, the immune system does a great job at targeting and eliminating abnormal cells. But many cancers are masked so well that even a perfectly functioning immune system will not recognize them as a threat. Such a simplistic and ignorant view of cancer is not helpful.
