Carole Baggerly is the founder director of GrassrootsHealth. Her organization’s mission is to increase awareness about vitamin D and the crucial role it plays in many aspects of your health.
Carole is on the cutting edge of vitamin D research, with her finger on the pulse of some of the world’s leading vitamin D scientists.
Prior to this focus, Carole’s educational background included physics and mathematics, and she owned and managed an aerospace business. However, her passion for vitamin D arose from a more personal experience. She is a breast cancer survivor and attributes a large portion of her healing to vitamin D.
Her particular combination of managerial and executive skills, education in the sciences and personal health battles make her uniquely qualified to get this critical information into the hands of the public.
I first interviewed Carole in 2011. In this second interview, Carole discusses what the latest science says about how vitamin D prevents and slows multiple forms of cancer, and why it’s so important to have your serum levels tested on a regular basis.
In fact, optimizing your vitamin D levels may help you prevent more than 16 different types of cancer including pancreatic, lung, ovarian, breast, prostate, and skin cancers.
Modest Vitamin D Levels May Decrease Your Risk of ALL Cancer by 77 Percent
Vitamin D has shown preventative benefits for many diseases, including heart disease and diabetes, and can even reduce chronic pain1. But when it comes to cancer, vitamin D is its worst enemy! Theories linking vitamin D deficiency to cancer have been tested and confirmed in more than 200 epidemiological studies, and understanding of its physiological basis stems from more than 2,500 laboratory studies.
One particularly noteworthy study was completed by Joan Lappe and Robert Heaney in 20072. A group of menopausal women were given enough vitamin D to raise their serum levels to 40 ng/ml.
These women experienced a 77 percent reduction in the incidence of all cancers, across the board, after just four years3. The remarkable thing is, 40 ng/ml is a relatively modest level. The latest information suggests the serum level “sweet spot” for vitamin D is 50 to 70 ng/ml. To have such stunning findings at just 40 ng/ml underscores just how powerful and important vitamin D is to your body’s optimal functioning.
Could Breast Cancer Be 90 Percent Preventable, Just with Vitamin D?
Vitamin D has powerful effects when it comes to breast cancer, to the degree that breast cancer is being described as a “vitamin D deficiency syndrome.” Of course, other lifestyle factors are also important in preventing cancer, such as nutrition, exercise, sleep, and managing stress. However, vitamin D’s critical importance seems to grow with every emerging study.
Carole believes that 90 percent of ordinary breast cancer is related to vitamin D deficiency — which is 100 percent preventable!
This is absolutely a profoundly important statement. As breast cancer is the most common cancer in women, this has massive implications for women’s health. For more information about breast cancer, I invite you to watch my informational video on the subject. Please be aware though that she is referring to more common types of breast cancer as opposed to inflammatory breast cancer and some of the other unique forms.
Vitamin D Can Make Breast Cancer Cells Fall Apart
The recently deceased Dr. Frank Garland4 was the epidemiologist who connected the dots between vitamin D deficiency and cancer. According to Garland, in nearly all forms of breast cancer, vitamin D affects the structure of your epithelial cells. These cells are held together by a glue-like substance called E-cadherin, which provides structure to the cell. E-cadherin is made up of mostly vitamin D and calcium.
If you don’t have adequate vitamin D, that structure comes apart and those cells do what they are programmed to do in order to survive — they go forth and multiply. If this growth process (cell proliferation) gets out of control, you may end up with cancer.
If you have breast cancer in progress, the addition of vitamin D can help stop cancer cells in their tracks by replenishing E-cadherin. Once cancer growth is slowed, your immune system can begin to get ahead of the cancer cells, because it doesn’t have to deal with gazillions of them. It’s just disposing of the “leftovers.” The theory above is Dr. Garland’s DINOMIT theory and has been substantiated by subsequent studies by other researchers
