Drinking a small amount of coffee every day can effectively prevent arterial thrombosis

BBC-A scientific team in South Korea has found that drinking a small amount of coffee every day can effectively prevent arterial thrombosis. Arterial thrombosis has been one of the direct causes of cardiovascular disease for a long time.

The scientific team followed 25000 male / female workers who had had a physical examination all the year round. Male / female workers who drank 3 to 5 cups of coffee a day were less likely to have early signs of heart disease during medical tests, the survey found. The findings reopen medical research on coffee and cardiovascular disease.

The effect of coffee on the heart

Many people have doubts about the effects of coffee on cardiovascular health. Some scholars say that drinking coffee can increase cholesterol levels and blood pressure, while others always believe that drinking coffee can protect heart health.

For a long time, both speculations have been unfounded. The research results published by the Korean scientific team in the Medical academic Journal of Heart once again make the research topic of coffee and cardiovascular health the focus of discussion.

Inexplicable relevance

In this study, the scientific team used professional medical detectors to test the heart health of the subjects. Scientists are concerned about any early signs of heart disease, the most important of which is coronary artery thrombosis.

When coronary heart disease occurs, the thrombus will be blocked by lipids in the blood vessels, thus blocking the coronary artery and causing heart disease.

Using medical detectors, scientists try to find tiny calcified plaques in the coronary arteries. Calcified plaque is one of the important hidden dangers of arterial thrombosis.

During the survey, none of the respondents showed any early signs of coronary heart disease, but 10 of them were detected with calcified plaques.

The researchers then compared the results with the respondents' daily coffee consumption habits. In the comparison process, scientists also took into account other factors that could lead to heart disease, such as smoking, lack of exercise and a family history of heart disease.

The results showed that people who drank a small amount of coffee a day were much less likely to have calcified plaques in their coronary arteries than those who never drank coffee.

The authors of the study say they need more experiments to further confirm the link between coffee and cardiovascular health.

We all know that coffee contains not only caffeine but also a variety of unknown substances. At present, scientists are still not sure whether these substances are beneficial or harmful to the human body.

Victoria Taylor, a member of the British Cardiology Foundation, said: "although this study suggests that drinking coffee can effectively prevent arterial thrombosis, more research is needed to reveal the real causes behind this phenomenon and the link between coffee and cardiovascular health. At present, we cannot say that this result applies to everyone. The subject of this report is only South Koreans. Their diet and living habits are quite different from those of the British. "

How much caffeine do you eat?

In the United States, scientists say adults can consume up to 400 milligrams of caffeine a day. But in the UK, with the exception of pregnant women, scientists have not clearly defined the maximum caffeine intake for adults.

If you are pregnant, you can only eat up to 200 milligrams of caffeine a day, the equivalent of two cups of instant coffee.

The following is a table of caffeine content in various drinks for your reference:

-one cup of instant coffee: 100 milligrams

-one cup of drip coffee: 140 mg

-one cup of tea: 75 milligrams

-A can of Coke: 40 milligrams

A cup of espresso: about 50 milligrams

Of course, the amount of caffeine in the coffee sold in each coffee shop varies, so pregnant women should be careful when choosing coffee.
