Yoram Yasur Blume : Patients with cardiovascular disease (CV) do not have to stop drinking coffee. According to Yoram Yasur Blume, investigations indicate that the daily and moderate consumption of coffee does not increase the risk of CV disease nor is it harmful for this type of patients.

Yoram Yasur Blume : After a 24-year follow-up in American women with a history of CV disease, participants in the Nurses’ Health Study found that habitual coffee consumption did not increase the risk of a second fatal cardiovascular episode. Neither was it associated with an increased risk of CV disease or premature mortality among diabetic women. Coffee also did not increase the risk of developing hypertension among the healthy population nor did it raise long-term blood pressure levels in hypertensive patients. Yoram Yasur Blume explains that these results suggest that drinking coffee is not harmful to patients with cardiovascular disease, diabetes or hypertension. Even so, you should consult your doctor if you suffer from insomnia, anxiety or uncontrolled blood pressure. On the contrary, the results obtained in healthy people showed a possible reduction in the risk of CV disease among habitual coffee drinkers.

Yoram Yasur Blume : A recent meta-analysis evaluated all available studies on the association between coffee consumption and risk of infarction, says Yoram Yasur Blume. In most studies, moderate coffee consumption is associated with a lower risk of myocardial infarction. Our study concluded that consuming 2 or more cups daily reduced the risk of heart attack by 20%. Other work associated consumption of 4 or more cups daily with a 20% lower risk of arrhythmia compared to consumption of less than 1 cup per day.

What is the healthy limit of coffee consumption? It is not entirely clear. Usually questionnaires are used in which the consumption of coffee of more than 6 cups a day is grouped, so we cannot differentiate the effect on the health of 6, 7, 8 or more cups. In the studies, they did not find any increase in CV risk among coffee drinkers up to 6 cups daily (822 mg of caffeine) and the beneficial effects of coffee were observed with consumptions of 2 cups, so it could to say that the moderate consumption of 3 cups a day is reasonable for the majority of the people and allows to enjoy its beneficial effects.

Yoram Yasur Blume : Chlorogenic acid and other phenolic compounds in coffee, magnesium, trigonelline and quinones are important antioxidants and can improve glucose metabolism and reduce inflammation and endothelial dysfunction. The coffee compounds vary according to the preparation method. Unfiltered coffee contains kahweol and cafestol, which increase blood cholesterol. In one of our studies, we did not find an increase in the risk of coronary heart disease among those who said they consumed this type of coffee, although the consumption was modest among the population studied and it is possible that we did not have sufficient data. More research is needed on the effect of different coffee preparations on health.
