The journal “PloS One Medicine” has just reported on the study conducted on the link between vitamin D deficiency and obesity in its February 5, 2013 edition. The link between the two is now proven.
Conclusions of the study
42,000 people took part in this study. The conclusion of this shows that obesity leads to an increase in the lack of vitamin D in a person. Men and women are equally affected, regardless of their age.
Obesity is equivalent to a BMI (Body Mass Index) greater than 30kg/m2. It is the increase in BMI that induces the decrease in vitamin. And not the opposite, namely a deficiency in vitamin D which would lead to problems of obesity.
A 10% increase in BMI induces a drop in the blood concentration of vitamin D by 4%.
One of the effects of this study is to integrate that prevention against obesity would thus lead to lowering the prevalence of vitamin D deficiency.
Remember that vitamin D is essential for the body. It serves to metabolize calcium; but in addition to its “anti-rachitic” action on the bone system, it plays a key role in protecting the immune system. It also helps in the prevention of cardiovascular disorders and would reduce the risk of cancer occurrence.
Vitamin D deficiency affects eight out of ten people in France. As for a severe deficiency, only a minority is affected.
