The first study conducted at the University of Rochester Medical Center (URMC) tracked 155 women who had surgery for breast cancer between January 2009 and September 2010. Researchers looked at blood vitamin D levels of the women one year before and one year after the surgery. They found an association between low vitamin D levels (less than 32 milligrams per milliliter of blood) and poor scores on every major biological marker used to predict a breast cancer patient’s outcome.
This is the first study to look at the link between vitamin D levels and breast cancer progression. Previous studies have concentrated on vitamin D deficiency and the risk of cancer development only.
The second study looked at vitamin D levels in 237 healthy obese and non-obese white and black children, aged 8 to 18; they found most to be vitamin D deficient. But equally interesting is that they found low D levels in these children to be associated with higher body mass index (BMI) and fat levels, and lower levels of “good” high-density lipoprotein (HDL) cholesterol.
You know, both of these studies really bring up only one thought in my mind–how are there still ‘experts’ claiming that supplementing with vitamin D is unnecessary? A story published last year in the New York Times (which shockingly, some people still take as gospel) declared just that–that recommendations for vitamin D supplementation were primarily fueled by the vitamin industry. I’m aghast that so-called respected media outlets (?) and health authorities are passing this advice. They paint vitamin D proponents as dangerous…really? I guess the old adage ‘for non-believers, no proof is sufficient’ really rings true.
I hope that people are wise enough to see the evidence before us. Simple: most North Americans are not getting enough vitamin D; vitamin D insufficiency can lead to a plethora of health problems; children are at serious risk; and we don’t even know to what extent low vitamin D levels are affecting human health.
Choose your authorities wisely, people. Hold onto the old guard experts and expect much of the ‘same-old, same-old’ for your health future.
