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).
