Dietary intake of magnesium from foods or from food and supplements is associated with improvements in diabetes-related outcomes, including metabolic syndrome, obesity or overweight, hypertension, and high-density lipoprotein cholesterol (HDL-C), according to a new study in the Journal of Human Nutrition & Food Science.
Data from the National Health and Nutrition Examination Survey (NHANES) over the years 2001–2010 of more than 14,000 adults aged >20 years was review to examine the association between dietary magnesium intake and health outcomes. Adequate magnesium intake was defined as meeting the estimated average requirement of 330–350mg/day for men and 225–265mg/day for women.
Adequate magnesium intake from food alone was linked to significantly reduced odds ratios for metabolic syndrome (0.88, P=0.0166), overweight or obesity (0.91, P=0.0305), hypertension (0.88, P=0.0205), elevated systolic blood pressure (0.87, P=0.0070) and reduced HDL-C (0.84, P=0.0039) vs. adults with inadequate intake of magnesium from food. Compared to adults with inadequate intake of magnesium from food plus supplements, adults reporting magnesium intake from foods in combination with dietary supplements showed significantly lower odds ratios for elevated glycohemoglobin (0.88, P=0.0046), obesity (0.92, P=0.85), overweight or obesity (0.86, P=0.0011), elevated waist circumference (0.88, P=0.0057) and reduced HDL-C (0.81, P=0.0034).
The results emphasize the importance of meeting magnesium intake recommendations with diet and dietary magnesium supplementation for associated health benefits, stated lead study author Yanni Papanikolaou.
