Researchers Examine Effects of Dietary Magnesium on Type 2 Diabetes Risk

JAMA. 2004;291(9):1056-1057. doi:10.1001/jama.291.9.1056

Eating foods rich in magnesium such as whole grains, nuts, and leafy green vegetables may prove to be a cost-effective approach to reducing the risk of developing type 2 diabetes, according to two epidemiological studies with large enrollment numbers and long follow-up .

The findings, published in the January issue of Diabetes Care, suggest a significant inverse association between dietary magnesium intake and diabetes risk, said the researchers from Harvard University's Medical School and School of Public Health in Boston, Mass, who performed the two studies. The investigators said that research in animals had previously shown that an adequate magnesium intake may enhance peripheral insulin sensitivity and glucose metabolism. In addition, a randomized, double-blind placebo-controlled trial with 63 enrollees with type 2 diabetes and decreased serum magnesium had found that oral magnesium supplementation improved insulin sensitivity and metabolic control (Diabetes Care. 2003;26:1147-1152).
