Obesity can lead to lower vitamin D levels
Another strike against obesity: it limits your body's ability to use vitamin D successfully. Researchers from the University College London Institute of Child Health found that vitamin D is stored in fatty tissue, and when there is a high prevalence of fatty tissue, the body has difficulty distributing the vitamin around the body.
The research linking obesity and vitamin D compiled the genetic data from 21 studies, gathered from a total of 42,000 people. From this data, the researchers found that for every 10 percent rise in BMI, there was a 4 percent drop in vitamin D capacity.
Vitamin D is most commonly absorbed through sun exposure or through supplementation. Low levels of vitamin D have been linked to softening and weakening of the bones, rickets in children, multiple sclerosis, rheumatoid arthritis and a variety of other conditions. It helps the body absorb calcium, promotes cell growth and immune function and reduces inflammation.
