Why is coffee useful?

Drinking several cups of coffee a day can help people avoid clogged arteries.

This is a known risk factor that can lead tocardiovascular disease, Korean researchers believe.

They studied more than 25,000 men and women who underwent routine health checks at their workplace. Employees who drink moderate amounts of coffee, 3 to 5 cups a day, have a lower risk of early signs of cardiovascular disease, medical tests show. p>

The findings have renewed the debate about whether coffee is good for the heart.

Heart Effects

There is a lot of confusion when it comes to the effects of coffee on heart health. Angiogram showing the coronary artery reveals that heart disease can block the arteries that supply blood to the heart muscle.

Some studies have linked the harms of coffee, such as increased cholesterol or high blood pressure, while others believe that the drink may offer good enough protection of the heart.

Ultimately, there is no conclusive evidence, and new research underway in South Korea, published in the journal Heart, adds little to the subject.

Unexplained link

In the study, researchers used medical tests to assess heart health. Specifically, they look for any disease of the arteries supplying blood to the coronary arteries.

More research is needed to confirm these facts and understand the reason for the associations.

“In coronary heart disease, the coronary arteries become blocked by a gradual build-up of fatty substance on their walls,” says Victoria Taylor of the British Heart Disease Research Institute. .

Researchers are trying to find calcium in the walls of coronary arteries to understand where the disease may be starting to develop. None of the volunteers in the Korean study showed signs of cardiovascular disease, but more than one in 10 of them had visible calcium deposits according to tests.

The researchers then looked at the test results of employees who consumed coffee regularly while also accepting other potential heart health risk factors such as smoking or having a family history of heart disease.

People who drink several cups of coffee a day are much less likely to build up calcium deposits in their coronary arteries than people who do not consume coffee or exceed their daily allowance. But the study authors reiterate that more research is needed to confirm and explain the link between the two.

Coffee contains a stimulant calledcaffeine, as well as a host of other compounds, but it is not clear whether this causes good or harm to the body.

“This study does highlight the potential link between coffee consumption and a lower risk of clogged arteries, but this factor is still subject to much research to these facts are confirmed,” said Victoria Taylor.

“You should be careful when analyzing these results and not jump to conclusions because the study is based on the South Korean population, which has a different eating style and lifestyle than people in other parts of the world,” she added. American experts claim that the daily dose of coffee that is considered safe is up to 400 milligrams.
