Research by the University of California shows that increasing sunlight and vitamin D intake will greatly reduce the risks of cancer and other debilitating diseases.
If vitamin D3 levels among populations worldwide were increased, 600,000 cases of breast and colorectal cancers could be prevented each year, according to researchers from the Moores Cancer Center at the University of California, San Diego (UCSD). This includes nearly 150,000 cases of cancer that could be prevented in the United States alone. The researchers estimate that 250,000 cases of colorectal cancer and 350,000 cases of breast cancer could be prevented worldwide by increasing intake of vitamin D3, particularly in countries north of the equator.
The study examines the dose-response relationship between vitamin D and cancer, and is the first to use satellite measurements of sun and cloud cover in countries where blood serum levels of vitamin D3 were also taken. Serum vitamin D levels during the winter from 15 countries were combined, then applied to 177 countries to estimate the average serum level of a vitamin D metabolite among the population.
An inverse association between serum vitamin D and the risk of colorectal and breast cancers was found.
To increase your vitamin D3 levels, the researchers recommended a combination of dietary methods, supplements and sunlight exposure of about 10 to 15 minutes a day, with at least 40 percent of your skin exposed.
Dr. Mercola’s Comments:
The dangers of sun exposure have been greatly exaggerated, and the benefits highly underestimated. Sun exposure is not the major reason people develop skin cancer. I know many of you might be surprised by this, but this is simply not the truth, and buying into this lie will most assuredly deprive you of the vital benefits the sun can provide.
And one of the major benefits is lowering your risk of getting cancer — the number one cause of death. As this groundbreaking study found, 600,000 cases of cancer could be prevented every year just by increasing your levels of vitamin D, and without question, the best way to obtain your vitamin D is by UVB sunlight falling on unexposed skin in doses that do not cause sunburn.
Even beyond cancer, the researchers pointed out that increasing levels of vitamin D3 could prevent diseases that claim nearly 1 million lives throughout the world each year!
That is absolutely extraordinary, and NO ONE is making a penny from this recommendation, which is one of the primary reasons why this is not being more widely promoted.
The Endless Benefits of The Sunshine Vitamin
Vitamin D, the sunshine vitamin, is different from other vitamins in that it influences your entire body — receptors that respond to the vitamin have been found in almost every type of human cell, from your brain to your bones.
Optimizing your vitamin D levels could help you to prevent as many as 16 different types of cancer including pancreatic, lung, breast, ovarian, prostate, and colon cancers.
Further, optimal vitamin D levels are also known to positively influence the following conditions:
- Heart disease
- Inflammatory bowel disease
- Rheumatoid arthritis
- Multiple sclerosis and osteoporosis
