Researchers have discovered that drinking moderate amounts of coffee may be beneficial to your heart health.
An analysis of five previous studies suggests that daily consumption of two 8-oz cups of coffee can reduce the risk of heart failure by 11%. These five studies were completed between the years 2001 and 2011, and they involved a total of 140,220 subjects. The analysis was published in an American Heart Association journal called Circulation: Heart Failure.
According to lead author of the analysis, Elizabeth Mostofsky, a research fellow at the Beth Israel Deaconess Medical Center, heart failurehas the same risk factors as other cardiovascular diseases, including type 2 diabetes and high blood pressure. Since coffee can lower the risk of diabetes, it can also provide some form of protection against heart failure.
However, coffee is only good for the heart if it is consumed in moderation.
Its protective quality will slowly decrease with higher consumption, and it may not offer any health benefit for those who drink more than four or five cups a day. Excessive consumption of coffee may also be potentially harmful.
The results of the analysis are in accordance with previous studies on the health effects of coffee. A study that was published in the New England Journal of Medicine showed that drinking at least two cups of coffee can improve longevity. According to the American Heart Association, it is best that heart failure patients consume no more than two 8-oz cups of coffee a day.
