Magnesium Intake and Risk of Type 2 Diabetes
Jia-Yi Dong, Pengcheng Xun, Ka He, Li‐Qiang Qin · Diabetes Care (2011)
TL;DR
Studies suggest that getting more magnesium in your diet is linked to a lower risk of developing type 2 diabetes.
What they did
Researchers searched the PubMed database through January 2011 to find relevant health research. They combined data from 13 prospective cohort studies. Together, these studies followed 536,318 participants and tracked 24,516 cases of type 2 diabetes.
What they found
Higher magnesium intake was linked to a lower risk of type 2 diabetes, with a relative risk of 0.78 (95% CI 0.73-0.84). Each 100 mg/day increase in magnesium intake was linked to a summary relative risk of 0.86 (95% CI 0.82-0.89). This link was significant in people with a BMI of 25 kg/m(2) or higher, but not in people with a BMI under 25 kg/m(2).
Why it matters
These findings suggest that eating foods with magnesium may support everyday health. Foods such as nuts, seeds, beans, and whole grains naturally provide magnesium. Studies suggest that adding more of these foods to meals is linked to helpful dietary habits.
Limits
The abstract notes that the link was not statistically significant for people of normal weight, but it does not discuss other study limits. This is general education, not medical advice.
