More Magnesium Matters
While magnesium is found in dietary sources such as green leafy vegetables, meats, starches, grains, nuts and milk, a number of surveys suggest that many adults fail to consume the Recommended Daily Allowance (RDA) for this essential mineral. Frank Christoph Mooren, from the Institute of Sport Sciences at the Justus-Liebig University (Germany), and colleagues enrolled 52 men and women in a study in which each received either a magnesium supplement (containing magnesium-aspartate-hydrochloride at a dose of 365 mg per day) or placebo for six months. At the study’s conclusion, the team found that two out of three measures of insulin sensitivity had improved significantly in those receiving the supplemental magnesium compared to the placebo group, and blood sugar levels, measured as fasting levels of glucose in the blood, had improved by about 7 percent in the magnesium-supplemented group compared with placebo.
Grab Some Grapes
A daily dose of the polyphenol resveratrol (found in purple grapes, red wine, peanuts and some berries) may prove useful in the treatment and/or prevention of type 2 diabetes. Researchers from Hungary’s University of Pecs studied 19 people with type 2 diabetes. Participants were randomly assigned to take resveratrol supplements (10 mg/day) or a placebo for four weeks. Results showed that insulin resistance decreased significantly in the participants who received the resveratrol.
