Vitamin D Fights Cancer

Vitamin D Fights Cancer


One out of every eight women will get breast cancer in their lifetime. Breast cancer is the most common cancer among women and is the fastest growing cancer among men. More than 207,000 women were diagnosed with breast cancer last year. If there was a new drug that lowered the risk of a woman having breast cancer by 50 percent, it would be all over the news. This news exists in a simple vitamin.


If women would take just 3,500 international units of Vitamin D3 a day, they would cut their chances of having breast cancer by half. Vitamin D has many far-reaching health effects and is one of the most potent anticancer nutrients there is. We may have to take much more if levels are already too low. The optimal blood level of Vitamin D is 60 to 90 nanograms per milliliter. This can be measured easily and should be done regularly.


Before choosing to supplement with Vitamin D, have blood levels checked, then vitamin D3 over the synthetic vitamin D2. Those with naturally dark pigmented skin are probably deficient in vitamin D. The dark pigment, melanin, protects our skin from the damaging rays of the sun, but also limits our ability to manufacture Vitamin D efficiently. Thus it is especially important for darker-skinned people to have their vitamin D levels checked.


The biggest risk factors when it comes to breast cancer are low vitamin D levels; estrogen dominance; toxic exposure (food, smoking, chemicals, plastics); iodine deficiency; and estrogen metabolism variance or dysfunction.


 A genetic predisposition or family history of breast cancer is not a sentence that a person will automatically get the disease. Epigenetics, which is the concept that the environment and its triggers supersede these genes as the determining factor. The environmental triggers and signals we give our genes are most important. Understanding these risk factors and measuring them helps determine the best course to take in reducing that risk and making sure that the cancer gene does not get turned on.


Take advantage of new science that allows a functional medicine practitioner to measure risk factors that influence health today and tomorrow.

Healthy Ways To Spend Time At Home
Global Brief: Natural Thinking Spending Time in Nature Increases Cognitive Performance
More of our time is spent indoors than ever before. One of the ways by which nature may improve cognitive function (i.e. the acquisition of and goal-oriented use of knowledge) is by improving memory formation and recall, specifically that of short-term or working memory, and goal-oriented or directed attention; the kind that requires focused effort. By comparing and contrasting 13 studies, a team of researchers has shed light on this complex interaction in research published in Frontiers in Psychology. The studies used the backwards digit span task, which requires participants to invert a series of numbers and repeat them back. All demonstrated significantly improved cognition in nature as compared to urban environments. The benefits of studies like this are two-fold: not only are we learning more about how the brain interacts with its environment, but also how to leverage this interaction to lead healthier, more productive and happier lives.
