Coffee is one of the most popular beverages in the world, with millions of people drinking it every day. It is known for its ability to keep people alert and energized, but its effects on the arteries have been a subject of much debate.

Some studies show that coffee may have a positive effect on the arteries, while others suggest that it may have negative effects. In this article, we will take a closer look at coffee’s effects on the arteries, and examine the limits of its beneficial and negative effects.

The Benefits of Coffee on Arteries

Studies have shown that moderate coffee consumption can have a positive effect on the arteries.

Coffee contains polyphenols, which are antioxidants that can help reduce inflammation and prevent oxidative damage, both of which are linked to the development of cardiovascular diseases. A study published in the Journal of the American Heart Association in 2015 found that participants who drank three to five cups of coffee per day had a lower risk of developing clogged arteries than those who drank no coffee at all.

Another study published in the European Journal of Epidemiology in 2019 found that regular coffee consumption was associated with a reduced risk of mortality from cardiovascular disease.

The study analyzed data from 378,256 participants in the UK Biobank and found that those who drank one to two cups of coffee per day had a 22% lower risk of dying from cardiovascular disease than those who drank no coffee at all.

The Negative Effects of Coffee on Arteries

While some studies have shown that moderate coffee consumption can have positive effects on the arteries, others have shown that excessive coffee consumption can have negative effects.

A study published in the American Journal of Clinical Nutrition in 2001 found that consumption of six or more cups of coffee per day was associated with an increased risk of coronary heart disease in women.

Other studies have found that excessive coffee consumption can increase blood pressure and damage the lining of the arteries, both of which can lead to the development of cardiovascular diseases.

A study published in the Journal of Hypertension in 2012 found that regular consumption of coffee was associated with a modest increase in blood pressure, especially in those who were not habitual coffee drinkers.

The Limits of Coffee’s Effects on Arteries

The positive and negative effects of coffee on the arteries are dependent on the amount of coffee consumed.

Moderate coffee consumption, which is usually defined as one to three cups per day, is generally considered to be safe and may even have beneficial effects on the arteries. However, excessive coffee consumption, which is usually defined as more than four cups per day, can have negative effects on the arteries.

The effects of coffee on the arteries may also be dependent on other factors, such as age, sex, and genetics.

For example, a study published in the American Journal of Clinical Nutrition in 2003 found that the positive effects of coffee on the arteries were more pronounced in women than in men. Another study published in the Journal of Internal Medicine in 2019 found that the beneficial effects of coffee on the arteries were attenuated in individuals with genetic variations associated with a higher risk of cardiovascular diseases.

The Bottom Line

Coffee can have both beneficial and negative effects on the arteries, depending on the amount consumed and other factors.

Moderate coffee consumption is generally considered to be safe and may even have positive effects on the arteries, while excessive coffee consumption can have negative effects. As with any dietary choice, it is important to consider your individual circumstances and to speak with a healthcare professional before making any changes to your diet or lifestyle.
