Claim: 75% of breast and colon cancer deaths could be prevented if we had between 40 and 60 ng/ml of vitamin D in our body. According to a research by Dr. Cedric F. Garland from the University of San Diego, CA, Department of Family and Preventive Medicine, if we increase and maintain the level of vitamin D in our body at 25 ng/ml to 40-60 ng/ml, it would prevent approximately 58,000 new cases of breast cancer, and 49,000 new cases of colon cancer each year, and 3/4 of deaths from these diseases could be prevented in the United States and Canada.
A reasonable target range is 40-60 ng/ml of vitamin D in your body. You can get vitamin D either by taking supplements or naturally by being exposed to a moderate amount of sunshine.
Further, according to the same research on a newer model, the cause of cancer is initiated by disrupting the communication between cells that is essential to healthy cell turnover due to low vitamin D and calcium levels. In other words, the cause of cancer starts with decoupling of healthy cells; however, vitamin D prevents decoupling of these cells in the early stage of cancer.
Check your vitamin D level with your doctor to determine what level your vitamin D should be! A reasonable target of vitamin D is 40 to 60 ng/ml.
The vitamin D level in the blood should maintain between 40-60 ng/ml, according to research published by Dr. Cedric F. Garland, University of California San Diego, School of Medicine. Approximately75% - 80% of people in the United States have below the normal range of vitamin D in their body.
According to observational studies, the rate of breast cancer decreases by about 30% when vitamin D levels are greater than 40 ng/mL compared to lower levels of around 20 ng/ml. It appears that risk of getting breast cancer decreases substantially as vitamin D levels increase from very low levels of less than 10 ng/ml to 20-30 ng/ml. Furthermore, the rate of getting breast cancer decreases at a slower pace from 20-30 ng/ml levels to around 50 ng/ml.
