Obesity and decline in vitamin D: a causal link
Obesity is a problem of public health recognized and more and more increasing in industrialized countries. Whether in the EU, obesity has many consequences on the population, regardless of age. Not to mention the appearance of certain related diseases, obesity raised other conditions in the short term and long term whose severity continues to concern health professionals.
Published in the medical journal PLoS Medicine, a recent study reported new evidence on the consequences of obesity. She would be involved in the reduction of the levels of vitamin D in the body. The study indicated that obesity is associated with vitamin D deficiency. Research has explored the causal link and the accuracy of the relationship between body mass index(BMI) and vitamin D (25-hydroxyvitamin D [25 (OH) D]) thanks to genetic markers.
To get results on this health news, the study published February 5, 2013 in PLoS Medicine has operated and analyzed data from 21 genetic studies on a total of 42,000 people. A conclusion noted that that an increase of 10% of the body mass index(BMI), used as an indicator of body fat, has led to a decline of 4% of the availability of vitamin D in the participating subjects.Vitamin D is stored in adipose tissue (fat-soluble vitamin, vitamin D is soluble in fats), and the authors of the study indicate that the larger capacity of storage in obese individuals can prevent vitamin D to properly circulate in the blood.
Produced naturally, vitamin D is essential in the mechanism of absorption of calcium and phosphorus. Vitamin D can be made through food supplements, but is also naturally found in food (cooked liver oil tuna, halibut, cod–liver oil liver oil,salmon, yellow egg, cooked mackerel, sardines in oil,… canned tuna).
This new study conducted by the authors of venus factor workout is to highlight the importance of monitoring and treatment of a vitamin D deficiency in people who are overweight or obese. Nutrient intake and genetics play a role in obesity, and this research is a point of order on the fact that physical activity, food and the quality of sleep, must not be taken lightly, since they can help correct both the weight and the lack of vitamin D – not to mention the psychological health benefits.
