The benefits of vitamin D in promoting bone health are already well known. A new study in Brazil shows that vitamin D may also contribute to an increase in insulin sensitivity, which reduces glucose levels and the risk of developing type 2 diabetes. Results published online today at menopause, the journal of the North American Menopause Society (NAMS).
Other recent studies have shown a clear correlation between vitamin D and glycemic control, suggesting that vitamin D increases insulin sensitivity and improves the function of pancreatic beta cells. In this cross-sectional study, in which 680 Brazilian women between the ages of 35 and 74 years old participated, the aim was to evaluate the possible link between vitamin D deficiency and elevated glycemia.
Of the women interviewed, 24 (3.5%) reported using vitamin D supplements. Vitamin D supplementation was found to be negatively associated with high glucose levels. Habitual exposure to the sun also provided the same connection, demonstrating that vitamin D deficiency is associated with high blood glucose levels.
The results of the study appear in the article "Higher serum levels of vitamin D are associated with lower levels of glucose in the blood."
“Although a causal relationship has not been proven, low levels of vitamin D can play a significant role in type 2 diabetes,” said Dr. Joanne Pinkerton, executive director of NAMS. "Adding vitamin D can help improve blood sugar control, but interventional studies are still needed."
Obesity and vitamin D deficiency may indicate a greater risk of developing breast cancer.
