Metabolic Syndrome is a group (3 or more) of the following conditions that increase the risk of heart disease, stroke and diabetes: high fasting blood glucose, elevated blood pressure, excess waist circumference, elevated triglycerides, and low HDL cholesterol. It is estimated that one in four American adults has metabolic syndrome.
In a large study involving 5,115 people ages 18 to 20 years at baseline and followed by 15 years, researchers found that high dietary magnesium was associated with a reduced likelihood of developing metabolic syndrome. Compared with those in the lowest quartile of magnesium intake, participants with the highest magnesium intakes were 31 percent less likely to develop metabolic syndrome."
The researchers stated, "...Magnesium intake may have beneficial effects on individual components of the metabolic syndrome." Magnesium may help regulate cellular glucose metabolism, and influence insulin secretion, as well as improve insulin sensitivity. Magnesium may help reduce blood pressure, lower triglycerides and help raise HDL levels.
Having just one of the components of metabolic syndrome can increase your risk of cardiovascular disease. Because of its important metabolic functions, magnesium is an important component of a heart healthy diet.
