Consuming too much coffee can be hazardous to our health, yet moderate consumption of coffee and caffeine seems to provide many health advantages. A study published by Annals of Internal Medicine demonstrated this by finding that those who consumed coffee were 17% less likely to die of any cause, 19% less likely to develop heart disease, and 18% less likely to contract cancer compared to non-coffee drinking individuals.

Research was conducted with over half a million participants from 10 European countries who consumed anywhere from zero to three cups per day of coffee, over 16 years. Participants who regularly consumed three or more cups had lower risks of death from cardiovascular and metabolic conditions such as Type 2 diabetes and coronary heart disease than non-coffee drinkers. The findings demonstrated this connection.

Coffee may lower the risk of such conditions due to its polyphenols such as chlorogenic acid and quercetin, which have been shown to help lower blood pressure. Furthermore, its high levels of phenols help improve glucose metabolism which benefits both heart health and brain wellbeing.

However, many studies linking coffee with improved heart health are observational rather than clinical trials, making it hard to ascertain exactly which factors contributed to observed results. It could be that those who drink more than three cups may tend to be healthier overall and thus biasing studies’ conclusions. Furthermore, many coffee drinkers add milk, sugar, flavors or nondairy creamers which increase caloric intake significantly; it is important to remember that each 8 ounce serving is just that!

Notably, reducing risk for cardiovascular disease does not directly correlate to lower rates of death; many factors come into play when predicting someone’s likelihood of cardiovascular disease or death including diet, lifestyle and genetics.

At present, most healthy adults may continue enjoying a daily cup of coffee (black, without sweeteners). However, coffee should not serve as a replacement for other forms of healthy living behavior.
