Coffee is one of the most popular beverages in the world, often reported as a cardiovascular risk factor, although this theory has not been scientifically proven. Most health advice websites contradict themselves when it comes to coffee as some say it is beneficial while others say that it is a major health risk. A large intake of coffee or other substance containing caffeine can increase the cardiac index, blood pressure and activate the sympathetic nervous system in people that are not habitual consumers. Moreover, coffee should not be consumed against medical advice. Nevertheless, no clear association between coffee and cardiovascular diseases, including myocardial infarction and hypertension has been evidenced. Some studies even show the beneficial effect of the beverage on the organism. So is coffee good for your heart after all?
A study published in the New England Journal of Medicine in 2012 showed that people who drank two-three cups of coffee a day were less likely to die in the next 13 years for any reason. This does not prove a cause-effect connection, although it provides grounds for further research. Other studies revealed that coffee consumption can have an effect on biological markers of coronary heart disease risk, such as insulin resistance, serum cholesterol, plasma homocysteine and blood pressure. Higher coffee consumption does not have any of these effects. Then the question appears: is coffee good for your heart if you drink it every day?
Long-term habitual usage of coffee can influence the reactions, as well as the psychological effects that are related to the type of coffee. Drinking coffee can also affect the biological pathways that cause coronary heart disease and result in long-term benefits. It can also compensate on the adverse effects or have no influence at all on the development of CHD.
Scientists at Beth Israel Deaconess Medical Center in Boston recommend a moderate consumption of coffee that is associated with positive effects. Researchers analyzed five studies on more than 140,000 people and revealed that those who drink a moderate quantity of the beverage daily, about 2 cups, can have a 11% less chance to develop heart failure. The strength of the coffee was not considered. A low consumption of coffee was not associated with negative or positive effects, and a high consumption, of about five cups a day, was linked with higher risks of heart failure.
But which health advice websites can you trust? In the end, is coffee good for your heart and bad for other organs? Research shows that coffee can reduce the risk of other diseases as well, such as several cancers, depression, stroke and dementia. The beverage has a bad reputation because in the past, animal studies revealed that caffeinated coffee causes high blood pressure. Some compounds, including antioxidants, can lower the risk of type 2 diabetes. However, the American Heart Association recommends no more than one or two cups per day for those who suffer from heart failure. In a nutshell, your coffee consumption should be moderate and you should not consume it against medical advice.
As you can see, like most things in our life, coffee requires moderation in order not to cause any health problems.
