Coffee is a popular beverage. According to the National Coffee Data Trends (NCDT), 63% of American adults drink coffee daily. Once suspected to be a cancer-causing agent, the World Health Organization (WHO) has removed coffee from its possible carcinogen list, and coffee can actually have positive health benefits.
A 2015 study in the journal Circulation found moderate coffee consumption (three to four cups daily) was associated with an 8 to 15 percent reduction in the overall risk of death.
Black coffee also contains a number of micronutrients, including potassium, magnesium and niacin.
