Magnesium intake may influence diabetes risk

October 27, 2010
A study by University of North Carolina researchers found that people who consume more magnesium, from food and vitamin supplements, may have a reduced risk of developing diabetes.

Published in the journal Diabetes Care, they reviewed the cases of about 4,500 young adults and their magnesium intake. Those who averaged 200 milligrams of magnesium for every 1,000 calories they consumed were 47 percent less likely to develop diabetes than those who consumed only 100 milligrams per 1,000 calories.

"Increasing magnesium intake may be important for improving insulin sensitivity, reducing systemic inflammation, and decreasing diabetes risk," wrote researcher Ka He.

The findings may explain why whole grains, which are high in magnesium, are associated with lower diabetes risk. The researchers theorize that magnesium may influence diabetes development because it is needed for several enzymes to help the body process glucose.

A clinical trial under way in the North Shore-LIJ Health System focuses on diabetes patients who also live with coronary artery disease and require a procedure to restore blood flow to the heart. The trial is comparing two diabetes treatments - heart bypass surgery and the use of coronary stents - to learn which is more effective.
