According to the American Heart Association (AHA), drinking up to five 8-ounce cups of caffeinated coffee a day may lower risk of cardiovascular disease, including heart disease, stroke and heart failure. Researchers found that this amount, which is about 400 milligrams of caffeine, appears safe for most adults.

In a new scientific statement published in Circulation, the AHA emphasized that the findings apply to moderate coffee consumption, not high-dose caffeine products such as energy drinks, and that benefits may vary depending on a person’s health, caffeine sensitivity and how the coffee is prepared.

According to ABC News, the new recommendations offer a comprehensive review of recent clinical trials that show that daily coffee can even reduce the recurrence of irregular heart rhythms in patients who have had corrective procedures by an impressive 39%. It can also lower the risk of developing Type 2 diabetes by 20% to 30%.

Based on the results of the latest research, consuming up to 400 mg of caffeine per day, or no more than three to five, eight-ounce cups of regular black caffeinated coffee per day —without sugars, sweeteners, flavors or added fillers — is considered safe for most adults, according to an AHA news release.

However, the AHA cautions that these results are true only for paper-filtered or instant coffee. Coffee that’s unfiltered such as espresso, French press, or Turkish coffee contain a natural component called cafestol that raises low-density lipoprotein or LDL, often referred to as the “bad” form of cholesterol which can clog arteries.

Furthermore, the AHA warned that the evidence supporting moderate coffee intake should not be applied to high-caffeine energy drinks or energy shots. Those products can deliver much higher doses of caffeine and may increase the risk of high blood pressure and irregular heart rhythms, especially in people who are sensitive to caffeine or who have underlying cardiovascular conditions.

Experts warn that inherited genetic characteristics govern how well your liver processes stimulants like caffeine. Coffee can also disrupt sleep patterns and spike blood pressure in certain individuals. People with preexisting cardiovascular conditions should consult their healthcare provider or cardiologist before indulging in up to five cups of coffee.
