Research From 100 Countries Proves This Strongly Protects Against Cancer

A recent paper reviewed ecological studies of the hypothesis that ultraviolet-B (UVB) light protects against cancer by stimulating the production of vitamin D. The review looked at geographical variation of cancer incidence and mortality rates.

The review was based largely on three studies from the United States, one each from Australia, China, France, Japan, and Spain, and eight multicountry studies of cancer incidence rates that collectively examined more than 100 countries. The review consistently found that the higher the solar UVB, the lower the incidence of 15 different types of cancer. There was also some evidence of a similar relationship for 9 additional type of cancer.

According to the study, as reprinted on the website Green Med Info:

"The evidence for the UVB-vitamin D-cancer hypothesis is very strong in general and for many types of cancer in particular."
