Scientists found coffee safe for arteries

An incredible amount of research has been done on the dangers or benefits of coffee for the human body, and debate about how it affects health continues to this day among physicians and nutritionists. Most of the fears, of course, are associated with the harm of coffee to the cardiovascular system, since the caffeine contained in the drink has the ability to increase blood pressure. And then another scientific experiment proved that coffee is absolutely safe for arteries, even if it is consumed in large quantities.

It was previously believed that the increase in blood pressure as a result of drinking coffee is caused by a decrease in the elasticity of the walls of the arteries. Because of these changes, pressure increases and the likelihood of heart attacks and other troubles associated with the work of the heart increases sharply. But scientists from Queen Mary's University in London showed that coffee was in vain accused of problems with blood vessels.

The study involved more than 8,400 people. In order to compare the effect of different amounts of coffee on the body, lovers of this drink were divided by the number of cups drunk per day. As a result, three groups were formed: people who consume less than 1 cup per day, coffee lovers who drink 1-3 cups, and real coffee lovers who drink 4-25 cups.

All participants in the experiment underwent thorough medical examinations aimed at studying the work of the cardiovascular system. It turned out that the elasticity of blood vessels is not affected by the amount of coffee consumed, and this indicator was the same for both those who drink coffee occasionally and those who absorb large quantities of coffee.

This study partially confirms other data that were obtained as a result of the study of more than 500 thousand coffee lovers from different countries of Europe. It was possible to find out that the use of coffee is not associated with diseases of the cardiovascular system, moreover, it reduces the risk of mortality. Scientists from the United States, who conducted studies involving more than 179,000 people, came to similar conclusions.

But not everything is so simple. In addition to caffeine in natural coffee, there is a substance called cafestol, which gives the drink bitterness and helps increase cholesterol. But at the same time, researchers note that there is almost no cafestol in instant coffee and filtered beverages.

In general, most researchers agree that moderate consumption of coffee does not harm, of course, if we are talking about a healthy person, without problems with the cardiovascular system.
