Waking up in the morning, we all dream of fresh delicious and fragrant coffee. People say that using a large amount of coffee negatively affects the human body. But American scientists have found the opposite. How does coffee actually affect the body? Doctors say a few cups of coffee a day have a positive effect on life expectancy. Experts observed people aged 38-73 years for 10 years from 2006 to 2016. The results are amazing. The risk of premature death is reduced by 14% in people who drink more than 5 cups of coffee a day. However, the life expectancy of people regularly consumes coffee is much higher than those who do not use it at all. As for other positive aspects, coffee helps to overcome excess weight, has a positive effect on digestion. But despite this, doctors argue that coffee still brings more harm than good. Coffee negatively affects the nervous, cardiovascular system and even leads to the development of various psychoses. The beverage washes out the substances and microelements that are useful for the body, such as potassium, magnesium, calcium. Everyone’s favorite drink needs to be consumed as much as possible, for pleasure and good for the body.
