Coffee consumption studies differ that coffee damages arteries, protects the heart, or has no effect on the cardiovascular system. New research on thousands of participants has once again emphasized the relationship between this favorite drink and heart health.
Does it not damage, protect or interfere with the health of the heart and blood vessel system?
Scientists have been trying for years to answer these questions because coffee is the world’s favorite beverage.
While some studies have suggested that drinking coffee can increase the risk of cardiovascular events, others show that this can help maintain heart health and blood vessel function.
Some studies show that drinking lots of coffee regularly contributes to aortic stiffness – that is, when the aorta, which is the largest blood vessel in the human body, becomes less flexible. Aortic stiffness can contribute to the risk of cardiovascular disease.
Meanwhile, other evidence shows that drinking more than three cups of coffee a day can protect against atherosclerosis, a condition in which plaque builds up in the arteries to prevent normal blood flow.
Now, a new study conducted by researchers at the University of London “Queen Mary” UK survey found that people who drink large amounts of coffee every day do not experience arterial stiffness, which means that coffee does not increase the risk of heart disease. Circuit problems don’t increase this way.
Lead author Professor Steffen Petersen and his colleagues presented the findings of the study yesterday at the BCS Annual Conference in Manchester, England.
The study was sponsored by the British Heart Foundation, a US registered charity that supports the assessment of heart health and blood flow.
Same results for all groups
In the new study, the research team analyzed data from 8,412 participants employed in the biobank study. At the BCC conference, the team stated that the participants agreed to conduct cardiac magnetic resonance imaging and other special examinations to help researchers determine their cardiovascular function status.
The participants also showed how much coffee they usually drank every day. According to this report, the researchers classified participants into three groups according to their drinking habits:
- People who drink one or more cups of coffee every day
- those who drink between one and three cups of coffee a day
- those who drink more than three cups of coffee a day
- Finally, Professor Petersen and the team excluded people who drank more than 25 cups of coffee a day, as well as people who initially suffered from heart disease.
When comparing arterial stiffness between the three groups, the researchers found no difference between moderate and heavy coffee (those who drank between one and three or more than three cups of coffee each day) and those who drank a cup of coffee. or less a day.
These results indicate that even drinking significant amounts of coffee will not affect arterial health, so that the health of the heart and blood vessels cannot be disturbed.
“Despite the extraordinary popularity of coffee in the world, various reports can prevent people from enjoying themselves, and while we cannot prove a causal relationship in this study, our study shows that coffee is not as bad as arteries, as the previous study showed” obviously co-author Kenneth Fung.
This finding remains valid after researchers discussed factors that might contribute to arterial stiffness, including age, gender, ethnicity, smoking status, alcohol consumption, height, weight, dietary habits, hypertension (hypertension), high cholesterol, and diabetes. .
What do we need and what should we not believe?
The researchers also found that moderate and heavy coffee drinkers were more likely to be men, regular smokers and often drinkers of alcohol.
“Although our study involved people who drank up to 25 cups a day, the average intake in the highest group of coffee intake was 5 cups per day, the safe limit,” Feng said.
Metin Avkiran, who is an Associate Medical Director of the British Heart Foundation and who was not involved in the current research, explained that such studies of the relationship between coffee consumption habits and heart health can make people better too. help make informed decisions.
