Drinking up to five 8-ounce cups of coffee per day may potentially lower the risk of heart disease, health experts said [2].
This finding suggests that a common daily habit could provide significant cardiovascular benefits for a large portion of the population. However, the protective effects depend heavily on the type of coffee consumed and the total amount of caffeine ingested.
Research published in the journal of the American Heart Association in the U.S. indicates that certain coffee preparations offer these benefits [4]. Specifically, heart-healthy links apply to instant coffee or coffee prepared with a paper filter [5]. These filtered versions contain compounds that may protect the heart, whereas other caffeinated beverages, such as energy drinks, are associated with higher risks [6].
Medical professionals said that the maximum recommended caffeine intake is 400 mg per day [1]. This limit is approximately equal to five 8-ounce cups of coffee [1]. While five cups per day is linked to a lower risk of heart disease [2], some reports suggest that consuming more than this limit could be harmful [4].
Experts distinguish between black coffee and additive-heavy drinks. While black coffee may have a protective effect [4], the addition of sugars, and creams can negate the health benefits. The distinction between filtered and unfiltered coffee is also critical, as paper filters remove certain oils that can impact cholesterol levels [5].
Doctors said that individuals should monitor their personal tolerance to caffeine to avoid jitters or sleep disruption. They also said that the heart-protective benefits are most evident when coffee is consumed in moderation within the recommended daily limits [2].

The distinction between filtered and unfiltered coffee is central to these findings, as the filtration process removes specific compounds that can otherwise interfere with cardiovascular health. While the data suggests a protective ceiling at five cups, the narrow window between a health benefit and potential caffeine toxicity underscores the importance of moderation and preparation methods.
