Our aim in this study was to assess the relationship between magnesium intake and risk of coronary heart disease (CHD) among men.
A total of 39,633 men in the Health Professionals Follow-up Study who returned a dietary questionnaire in 1986 were followed up for 12 years. Intakes of magnesium, zinc and potassium and other nutrients were assessed in 1986, 1990 and 1994. Total CHD incidence (nonfatal myocardial infarction (MI) and fatal CHD) was ascertained by biennial questionnaire and mortality surveillance confirmed by medical record review. Standard CHD risk factors were recorded biennially.
These results suggest that intake of magnesium may have a modest inverse association with risk of CHD among men.
