Across the globe, individuals consume an estimated 2.25 billion cups of coffee per day. Coffee contributes a range of biologically active compounds, including many with antioxidant activity. The National Coffee Association reports clinical research documenting that drinking coffee is associated with unique health benefits related to longevity, cancer, diabetes, cardiovascular disease, stroke, liver and kidney health, and mental health.
