Every day, the world’s population consumes about 1.6 billion cups of coffee.1 In the United States, specifically, 64% of adults drink coffee daily.2 Among daily coffee-drinkers in the U.S., adults drink an average of 3 cups of coffee per day.2 I would consider this amount of coffee consumption as “moderate”; federal agencies claim it is safe to drink 3-5 cups of coffee each day.3
Most research on the benefits of coffee consumption are based on ~4 cups of coffee per day. Thus, the following list of benefits are only evidence-based for moderate coffee consumption. Drinking higher amounts of coffee may reduce benefits and increase risks. Continue reading for 20 potential benefits of (moderate) coffee consumption according to current research.
