Moderate tea consumption slowed the progression of coronary artery calcium and reduced risk for cardiovascular events, a recent study found. Coffee and tea data were examined from 6,508 ethnically-diverse participants in the Multi-Ethic Study of Atherosclerosis with intake for each classified as never, occasional (<1 cup/day), and regular (≥1 cup/day). Researchers found:

• Participants who regularly drank tea (>1 cup/day) had a slower progression of coronary artery calcium vs never drinkers over a median follow-up of 5.3 years.

• There was a statistically significant lower incidence of CV events for >1 cup/day team drinkers (HR, 0.71).

• Regular coffee intake (>1 cup/day) was not statistically associated with coronary artery calcium progression or CV events (HR, 0.97), when compared to never coffee drinkers.

• Caffeine intake was marginally inversely associated with coronary artery calcium progression.

Commentary: An article we reviewed about a year ago with over 4 million person-years of observations showed that increased coffee intake is associated with decreased cardiovascular disease, neurological disease, suicide and total mortality.¹ Other studies have shown coffee consumption to be associated with a decreased risk of type 2 diabetes, Parkinson disease, and fatal prostate cancer.² Now tea appears to have positive benefits on CV outcomes as well. —Neil Skolnik, MD
