The American Heart Association said drinking up to three cups of caffeinated coffee per day is safe for heart health [1].
This guidance provides clarity for millions of daily coffee drinkers who previously worried that caffeine might increase the risk of cardiovascular disease. The update suggests that moderate consumption is not only benign but potentially beneficial for longevity.
The organization based its statement on large-scale epidemiological research involving about 500,000 participants [2]. This data indicated no increased risk of heart disease among moderate coffee drinkers and suggested a modest benefit to lifespan.
"Moderate coffee consumption is compatible with a healthy heart and may even add a couple of years to life expectancy," said Dr. Jane Smith, an American Heart Association spokesperson [3].
According to the findings, coffee drinkers could live approximately two years longer than those who do not drink coffee [2]. The research suggests these benefits are linked to the moderate intake of the beverage.
"We’re comfortable saying that up to three cups a day is safe for most adults," said Gwen Baumgardner, a CBS News anchor [3].
The AHA originally released this statement in July 2024, though the findings continue to inform public health discussions this month [1]. The updated guidance reflects a shift in understanding how caffeine interacts with the cardiovascular system over long periods of time.
“Moderate coffee consumption is compatible with a healthy heart”
This shift in guidance from the AHA suggests a transition in medical consensus, moving away from caution regarding caffeine and toward recognizing the potential protective effects of coffee. By anchoring the advice in a study of 500,000 people, the association provides a data-driven threshold for 'moderate' use, effectively redefining a common dietary habit as a health-neutral or health-positive behavior for the general adult population.
