Vitamin D may decrease diabetes risk, according to new research

Posted on: June 18, 2018   by  Rachel Namery & John Cannell, MD


Type II diabetes is a metabolic disease that is far too prevalent across the globe. For example, in 2013, half of the population in China was prediabetic; a condition in which fasting glucose levels are between 100 -125. Individuals with prediabetes are at a greater risk of developing type II diabetes. Unlike most diabetes, prediabetes is reversible if caught early and fixed with healthy lifestyle changes.

Rates of type 2 diabetes have increased markedly since 1960 in parallel with obesity. As of 2015 there were approximately 392 million people diagnosed with the disease compared to around 30 million in 1985, a ten-fold increase in 30 years. Interestingly, those born in the summer have a lower risk of developing type II diabetes.

Vitamin D status plays a crucial role in helping prevent many diseases including some cancers, multiple sclerosis, cardiovascular disease, osteoporosis and diabetes. Studies have shown a direct correlation between vitamin D deficiency and insufficiency with obesity and type II diabetes. Doctors and scientists theorize this relationship is because of vitamin D’s ability to help regulate pancreatic beta-cell function, insulin action and inflammation. With so much compelling research on vitamin D, it is becoming clearer that levels need to be monitored as a part of a proactive approach to one’s health.
