Diabetes Risk Rises Dramatically When Obesity Is Combined With Vitamin D Deficiency

Research has shown that vitamin D insufficiency and obesity are individual risk factors for insulin resistance and diabetes. But new U.S. research shows that when you combine the two, the odds of insulin resistance rise to an even greater degree. Obese individuals in the study who had healthy levels of vitamin D were 20 times more likely to have insulin resistance than the overall study population. But obese individuals who also had low levels of vitamin D were 32 times more likely to have insulin resistance. Further research could help determine whether vitamin D supplements would reduce insulin resistance.
