What kind of coffee can be harmful

This is reported by Norwegian scientists who have been studying the effect of coffee on the body for more than 20 years.

The study was conducted from 1985 to 2003. It involved 500 thousand people aged 20 to 79 who consumed coffee prepared in different ways. The way of life of people was also taken into account. As a result, researchers at the University of Gothenburg concluded that there is a link between coffee brewing methods, heart attacks and life expectancy.

The most harmful was unfiltered coffee, and coffee brewed directly in the cup . It contains a large number of substances that increase "bad" cholesterol. The most harmful option is when the coffee grounds remain in hot water for a long time. Also, less healthy drinks include espresso, cappuccino, Turkish coffee, coffee brewed in a French press.

Filter coffee turned out to be the most useful - coffee prepared by the method of a single flow of hot water through a layer of ground coffee located on the filter. Moderate consumption of this coffee reduces the risk of death from cardiovascular disease. The lowest mortality among study participants was among those who drank one to four cups of filter coffee per day. Moreover, drinking such coffee turned out to be even more useful than completely abandoning the drink.
