Magnesium-containing foods may reduce risk of type 2 diabetes

While obesity remains the strongest risk factor for type 2 diabetes, there is growing evidence that particular foods may reduce risk.

High consumption of whole grains, beans, nuts, fruits and vegetables has been associated with a lower risk.

Swedish researchers, noting that these foods are rich sources of magnesium, identified seven published studies which identified magnesium intake and incidence of Type 2 diabetes and reviewed the results.

They found that people with lower magnesium intakes had a higher risk of developing Type 2 diabetes.

Supporting the hypothesis, animal studies have shown a link between magnesium intake and insulin sensitivity.

The researchers highlight that while the results are compelling, they are not definitive: people consuming more magnesium in their diets may also be leaner, more physically active and less likely to smoke.

Not all of the studies included in the analysis adjusted for these factors. The researchers support advice to consume more whole grains, beans, nuts, fruits and vegetables.
