Researchers from MCP Hahnemann University in Philadelphia discovered that a magnesium-poor diet increases insulin resistance in black Americans.
According to the August issue of The American Journal of Hypertension (AJH), 179 young black Americans (90 men and 89 women) were recruited for a study designed to determine whether dietary magnesium intake is associated with insulin sensitivity or blood pressure. Twenty-seven percent of the study group had a family history of diabetes.
While the researchers did not find a link between blood pressure and magnesium in the diet, they did discover a relationship between magnesium intake and insulin resistance.
“Studies have shown that a diet low in magnesium can lead to glucose intolerance,” says Michael Weber, MD, and editor of the AJH.
The daily average Recommended Dietary Allowance of magnesium is 410 mg. for men and 315 mg. for women. R. Keith Campbell, RPh, CDE, professor of pharmacy department at Washington States University, recommends 800 milligrams of magnesium twice per day. However, he points out that one of magnesium’s side effects is runny stools.
Foods such as nuts, seafood and whole grains also provide good magnesium sources.
