TUFTS UNIVERSITY: TYPE 2 DIABETES PREVENTION: VITAMIN D A FACTOR?

Vitamin D, aka Sunshine Vitamin

In a new study of 2029 participants of the Diabetes Prevention Program (DPP), Tufts researchers found that highest risk patients with the highest blood levels of vitamin D were 28% less likely to develop type 2 diabetes than those patients with the lowest levels of the vitamin.

Previous studies measured participants’ vitamin D status only once; researchers in the DPP tested participants’ vitamin D blood levels multiple times over an average of 2.7 years.

After adjusting for other risk factors for diabetes and for DPP lifestyle interventions in 50% of the participants, those in the top one-third of vitamin D status were significantly less likely to progress to type 2 diabetes.

Tuft’s Anastossios Pittas, MD, cautioned, “The findings are very promising but do not prove cause and effect, and the evidence to support general supplementation with vitamin D for diabetes prevention does not currently exist.”

My Take on the study:  The results of the study persuade me to adopt the spirit of Blaise Pascal’s famous wager:  What’ve I got to lose?  I’ll keep taking vitamin D.
