Does coffee give people a heart attack?
The good news: 20 years of medical research has found that drinking coffee can prevent liver cirrhosis, make people feel happy, responsive, and improve memory.
The bad news: if you have symptoms such as poor sleep or heartburn, it's best not to drink coffee. A study by the University of Toronto in Canada found that about half of people carry some kind of mutant gene, and drinking three cups of coffee a day increases the risk of heart disease by 36%.
Bottom line: it's no problem to drink 3 cups of 1m / m every day. If you have a heart attack, you can only drink filtered coffee. The cholesterol-raising ingredients in coffee are screened out by the filter.
