High coffee consumption is no worse for arteries than drinking less than one cup a day. If they become stiff, it can increase the workload in the heart and increase the likelihood of a person suffering a heart attack or stroke.
The limit seems to be 25 cups, according to a study presented at the British Cardiovascular Society Conference in Manchester and which has been conducted by researchers at the Queen Mary University of London.
Average consumption of 5 cups
Although the study included individuals who drink up to 25 cups a day, the average consumption among the highest coffee consumption group was 5 cups a day. With everything, 25 cups seemed to be equally safe for cardiovascular health.
Some previous studies have suggested that coffee hardens the arteries, puts pressure on the heart and increases the likelihood of a heart attack or stroke, and drinkers are warned to reduce their consumption. The arteries carry blood that contains oxygen and nutrients from your heart to the rest of your body.
However, a new study conducted in over 8 000 people throughout the United Kingdom He has found that drinking five cups a day, and even up to 25, was no worse for the arteries than drinking less than one cup a day.
The experts of the Queen Mary University of London (QMUL) divided 8,412 people into three groups for the study. The first group drank less than one cup of coffee a day, the second between one and three cups, and the third more than three. Some people in this last group drank up to 25 cups a day, although the average in that group was five cups per day.
All study participants underwent cardiac magnetic resonance imaging examinations, and the results remained solid even after factors such as age, weight and smoking status were taken into account. As explained by the researcher Kenneth Fung:
While we cannot demonstrate a causal link in this study, our research indicates that coffee is not as bad for arteries as previous studies would suggest.
The effects of coffee will have to be studied with larger and more diverse groups to offer general advice in one direction or another. Coffee contains several stimulants, such as caffeine, whose consequences on the body are still unclear. The results of another study, published in the journal Heart, add to the debate about whether coffee is good for health, because it also reflected that people who consumed coffee in moderation (three to five cups a day) They were less likely to show the first symptoms of heart disease.
