Two to three cups of coffee a day is good for the heart – What three new studies show

by

The consumption two to three coffees a day it seems that does good to the heartreducing the risk of coronary disease, Cardiac arrhythmia and inadequacywhile also promotes longevityaccording three new scientific researchespresented at its annual conference American College of Cardiology.

The benefit applies to both people with cardiovascular disease and those without such a diagnosed problem. New studies, according to scientists, reassure that coffee does not create new cardiovascular problems, nor does it exacerbate existing ones, while seems to work protectively as well.

“Because coffee can speed up your heart rate, some people worry that it could trigger or worsen certain heart problems. From this can come a general medical advice to cut coffee. But our data show that daily coffee consumption should not be discouraged, but rather coffee should be considered part of a healthy diet for people with and without heart disease. “We found that coffee consumption had either a neutral effect, meaning it did not cause any harm, or was associated with heart health benefits,” said the head of the three studies. Professor of Medicine Peter Kistler Australian Alfred Hospital, Baker Heart Institute and University of Melbourne.

THE first research analyzed data for 382,535 people with average age 57 years and without known heart disease. Those who drank two to three coffees a day, had the greatest benefit, approximately 10% to 15% lower risk of coronary heart disease, heart failure, heart arrhythmia or premature death from any cause. The risk was higher for those who drank less or more coffee than two or three. On the other, the risk of stroke the cardiovascular death it was smaller among those who drank a coffee a day.

THE second study in 34,279 people with a diagnosed cardiovascular disease also showed that two to three coffees a day were associated with less likely to die, compared to those who did not drink coffee at all. Consumption of any amount of coffee did not increase the risk atrial fibrillation or other heart arrhythmia. Those who already had an arrhythmia and drank coffee a day had an almost 20% lower risk of death than those who drank no coffee.

“Coffee lovers can rest assured that they can continue to enjoy it even if they have heart disease,” said Dr. Kistler. As he said, “there is one full range of mechanisms through which coffee can reduce mortality and have a beneficial effect on cardiovascular disease. People often equate coffee with caffeine, but coffee actually contains over 100 biologically active substances. They can help reduce oxidative stress and inflammation, improve the body’s sensitivity to insulin, stimulate metabolism, inhibit the absorption of fat from the intestine and block receptors known to be involved in abnormal heart rhythms. .

THE third study focused on whether there are differences in the relationship between coffee and cardiovascular disease depending on whether one drinks coffee with or without caffeineas well ground or instant. It has been found again that regardless of the type of coffee, two to three coffees a day are associated with a reduced risk of arrhythmia, blockage of arteries or heart failure. THE “Decaffeinated” coffee does not seem to reduce the risk for arrhythmia or heart failure, but reduces the risk of cardiovascular disease. In general, according to researchers, caffeinated coffee seems preferable.
