No Proof Vitamin D Prevents Development of Type 2 Diabetes.
Previous research has suggested that high levels of vitamin D may protect individuals from developing type 2 diabetes; however, a new study has found no evidence that high levels of vitamin D can prevent type 2 diabetes and that the only proven way to prevent type 2 diabetes is through a combination of diet and exercise. Study author Dr. Nita Forouhi writes, “Our findings suggest that interventions to reduce the risk of type 2 diabetes by increasing concentrations of vitamin D are not currently justified. Observational studies that show a strong and consistent higher risk of type 2 diabetes with lower levels of vitamin D may do so because they have thus far not been able to adequately control for distorting or confounding factors, such as physical activity levels.”
