|Sweeping New Guidelines for Prevention of Breast, Prostate & Colorectal Cancers|
|Foundation for Cancer Research & Wellness is embarking on a new campaign to educate people on the preventative and health promoting qualities of Vitamin D.|
|“We strongly recommend that adults should take up to 2,000 international units (IU) of vitamin D supplements daily.” This is the recommendation from Foundation for Cancer Research & Wellness.
The new guideline, with wide-ranging implications not only for cancer prevention but also for public health policy, is based on the growing scientific evidence that links vitamin D with up to a 77-percent lower risk of breast, prostate and colorectal cancers.”We believe this to be one of the most significant, lowest-cost, and highly-effective cancer prevention protocols ever,” says Greg Anderson, Founder of the Cancer Recovery Foundation Group of Charities. “This is in the same league as not smoking. While more research is certainly needed, we want people to know and act on this information now. As further research becomes available, we will update our recommendations.”In consultation with one’s primary healthcare provider, the Foundation is recommending:
The recommended amounts take into consideration, and are in addition to, vitamin D from other sources including food and multivitamins. The recommendation is particularly important to adults at risk of having low levels of vitamin D. This includes people with dark skin, those who do not go outside often and people who wear clothing covering most of their skin. The elderly are also in this group.
The new guidelines are based on a long history of vitamin D’s efficacy in cancer prevention and include two significant recently published research studies. A four-year randomized trial at Creighton University, published in the American Journal of Clinical Nutrition, found that the higher the level of vitamin D in the blood, the lower the relative risk of all cancers in post-menopausal women. Another study released last month demonstrated that women who consume more calcium and vitamin D were less likely to develop breast cancer before menopause.
“Our study shows that with adequate vitamin D, cancer can be prevented—or a high incidence of it can,” said Joan Lappe, PhD, RN, professor of nursing and medicine at Creighton and lead author of the study. “This is the first study that shows, in a clinical trial, that adequate levels of vitamin D can actually reduce the incidence of cancer.”
Vitamin D is often referred to as the “sunshine vitamin” and is actually a fat-soluble hormone that the body synthesizes naturally. Vitamin D2 is synthesized by plants while vitamin D3 is synthesized by humans when the skin is exposed to ultraviolet-B (UVB) rays from the sun. For years it has been known that the vitamin helps maintain bones and muscles. Now mounting evidence indicates vitamin D is essential in defending against as many as 18 different cancers.
Dr. Michael Holick, Professor of Medicine at Boston University Medical Center and an international authority on vitamin D, concurs. “We now recognize that every tissue and every cell in the body needs vitamin D. This vitamin tells cells to keep their growth in check and helps keep them from becoming [cancerous].”
It is not easy to get enough vitamin D. Diet is a primary source with milk, cereals and even orange juices claiming to be “fortified” with Vitamin D2, the form that is much less well-utilized by the body. Good natural sources of Vitamin D3 include eggs, salmon, tuna, mackerel and sardines.
In addition to diet, daily exposure to sunlight is also helpful. However, Anderson cautioned against relying too much on sunlight for vitamin D. “The issue is skin cancer. Unprotected sun exposure, even just a few minutes a day, increases skin cancer risk. More research studies are needed about sunlight exposure and vitamin D. But this much is clear, too much sun is bad. That’s why people need to start taking the supplement now.”
Foundation for Cancer Research & Wellness is not revising its SunWise® guidelines. The Foundation recommends that people limit their exposure to the sun, especially between the hours of 11:00 am and 4:00 pm, the time when the sun is most damaging to the skin. It is also strongly recommended to use a sunscreen with sun protection factor (SPF) 15 or higher, SPF 30 or higher for those who work outdoors or when people plan to be outside most of the day.
Since the recent research on links between vitamin D and cancer has focused on adults, the Foundation does not yet have a recommendation for children.
“Foundation for Cancer Research & Wellness wants people to be pro-active,” said Anderson. “The evidence for vitamin D is overwhelming. The government routinely approves toxic and expensive drugs on much less-convincing proof. This is a vitamin, a natural hormone. At these levels, it is safe. It is going to help prevent disease. Take up to 2,000 IU of vitamin D a day.”
