A dose–response meta-analysis of prospective cohort studies found that increasing dietary magnesium intake is associated with a reduced risk of stroke, heart failure, diabetes, and all-cause mortality. The analysis included more than 1 million participants in 40 prospective cohort studies published through May 31, 2016. During the follow-up periods (ranging from 4 to 30 years), 701 cases of heart failure, 14,755 cases of stroke, 26,299 cases of type 2 diabetes (T2D), and 10,983 deaths were reported. Significant association was observed between increasing dietary magnesium intake (per 100 mg/day increment) and the risk of heart failure (Relative Risk [RR]: 0.78) and stroke (RR: 0.93). Moreover, the summary RRs of T2D and mortality per 100 mg/day increment in magnesium intake were 0.81 and 0.90, respectively. A major cause of magnesium deficiency is an improperly balanced diet. Consuming a wide variety of magnesium-rich foods (such as green leafy vegetables, nuts, beans, and whole grains, etc.) will help ensure adequate daily intake of magnesium.

对前瞻性群组研究的量效关系荟萃分析发现，增加膳食镁摄入量与中风，心衰，糖尿病和全因死亡的风险降低有关。该分析包括了截至2016年5月31日发表的40项前瞻性群组研究， 超过100万参与者。随访期间（4至30年）报告了701例心衰，14,755例中风，26,299例2型糖尿病，10,983例死亡。膳食镁摄入增加（每增加100毫克/天）与心衰（相对风险：0.78）及中风（相对风险：0.93）风险之间观察到显着的相关。此外，镁摄入量每增加100毫克/天，2型糖尿病和全因死亡的相对风险分别为0.81和0.90。缺镁的主要原因是饮食未适当地平衡。食用各种富含镁的食物（如绿叶蔬菜，坚果，豆类, 和全谷类等）将有助于确保每天摄入足量的镁。来源：http://bmcmedicine.biomedcentral.com/
