Researchers looked at the dietary magnesium intakes of 4,637 Americans, aged 18 to 30 years, who were free from metabolic syndrome and diabetes at baseline. During 15 years of follow-up, 608 people developed metabolic syndrome. Results showed the multivariable-adjusted hazard ratio of metabolic syndrome for participants in the highest quartile of Mg intake was 0.69, compared with those in the lowest quartile of intake. In other words, people with the highest Magnesium intake were about 30% less likely to develop Metabolic Syndrome. They also showed Mg intake was inversely correlated to individual components of the metabolic syndrome, including fasting insulin levels. Or in plain English, the more Magnesuim one took, the lower the fasting insulin levels were. The researchers concluded young adults with higher magnesium intake have a lower risk of development of metabolic syndrome. The study appeared in the March 27 issue of Circulation (113:1675-82, 2006).
