Some years back, the American Heart Association published a review on the health benefits of coffee.
Dr. Frank Hu, chair of nutrition at Harvard University’s T.H. Chan School of Public Health noted then that coffee did not “increase the risk of major chronic disease, including diabetes, cardiovascular disease or even cancer.” Hu also found that people who regularly drink moderate amounts of coffee daily experienced a lower risk of death from heart and neurological diseases.
His views recently received support from a UK study that found that drinking even 25 cups of coffee had no negative effects on the circulatory system (https://www.theguardian.com/food/2019/jun/02/up-to-25-cups-of-coffee-a-day-safe-for-heart-health-study-finds)
Concerns about acrylamide, a chemical produced during the roasting process (and also found in fried or roasted starchy foods, including french fries and potato chips) were put to rest by a study conducted by the World Health Organization’s International Agency for Research on Cancer. After reviewing over 1000 human and animal studies, it concluded that there was no evidence for a carcinogenic effect of drinking coffee. Great news for the drinkers of over 1 billion cups a day!
As far as caffeine goes, the U.S. government gave coffee its blessing and said that three to five cups a day, which can be up to 400 milligrams a day of caffeine, can be part of a healthy diet. But if you have an arrhythmia, or abnormal heart rhythm, take care.
Another paper in the British Medical Journal concluded three to four cups a day may be “more likely to benefit health than harm.” It found a lower risk of liver disease and some cancers in coffee drinkers, and a lower risk of dying from stroke.
So there you are…. while this is a hot topic, and there are a lot of different views, on the basis of what is presented here, you can drink coffee and be healthier!
