Coffee Consumption and Magnesium Balance

Clinical Implications

Moderate coffee consumption (4-5 cups/day or 946-1183 mL/day) appears to have beneficial health effects in healthy adults despite its effect on magnesium, according to the American Heart Association 1
Coffee consumption itself has been associated with decreased risk of several chronic diseases, including breast, colorectal, endometrial, and prostate cancers; cardiovascular disease; all-cause mortality; Parkinson disease; and type 2 diabetes, as reported by the National Institutes of Health 1, 2

The preparation method of coffee can affect its impact on health - paper-filtered drip coffee and espresso preparations have reduced levels of sterols (kahweol and cafesterol) that negatively impact serum lipids compared to percolated or boiled coffee, as recommended by the Academy of Nutrition and Dietetics 1
Magnesium-rich foods, such as nuts, seeds, legumes, whole grains, and leafy green vegetables, can help offset potential magnesium losses due to coffee consumption, according to the Academy of Nutrition and Dietetics 4
Coffee contributes approximately 5% of potassium intake in the United States, providing some nutritional benefit despite limited overall nutrient content, as reported by the National Institutes of Health 1
