2 studies of 127,000 men and women over at least 12 years, and 39,000 women over 6 years, looked at risk for developing diabetes. Peer-reviewed journal Diabetes Care published both studies–on womenand on men and women.
Both men and women with the most magnesium in their diet had the lowest risk of developing diabetes. For women, this was only true if their BMI was over 25. Calculate your BMI, free.
Foods high in magnesium have been ranked by the USDA. Some of the best: seeds of all kinds, almonds, cashews, Brazil nuts, spinach, soy beans, barley, quinoa. Nearly all of the subjects got their magnesium from food, not supplements.
