Low mineral intakes might be a contributing factor in metabolic syndrome, according to a study from Kongju National University in South Korea. Dietary intakes of magnesium, manganese, and copper were gathered on 5,136 adults (2,084 men and 3,052 women) from the 2007-2008 Korea National Health and Nutrition Examination Survey (KNHANES). The intakes of people with metabolic syndrome were compared to intakes of healthy adults. Among study participants, 25.9% (540 subjects) of the men and 24.5% (748 subjects) of the women met diagnostic criteria for metabolic syndrome. Results showed that men with metabolic syndrome had significantly lower levels of magnesium and copper compared to controls.
In women, dietary intakes of magnesium, manganese, and copper were lower in the metabolic syndrome group. The women with high blood pressure showed significantly lower intakes of all three minerals compared to control subjects. In addition, in women, the highest quartile of magnesium and copper intakes was inversely associated with metabolic syndrome. The researchers conclude that, “ …[since metabolic syndrome]incidence increases and dietary intake and nutrient density decrease with increasing age, and mineral intake is reduced accordingly, these results suggest that meal management with adequate mineral intake is advisable to control [this disease].”
