Many people depend on coffee in the morning to boost energy, alertness, and concentration levels – providing energy, alertness, and increased concentration for daily tasks. Coffee has also been associated with numerous health benefits – including lower risks of stroke, heart disease, Type 2 diabetes and certain cancers, as well as decreasing chances of premature mortality related to such conditions or other causes. But how much coffee is safe to drink each day?

An observational study published online Sept. 27 in the European Journal of Preventive Cardiology shows that coffee consumption, in moderation, can help increase longevity and lower cardiovascular disease and early death risk. Nearly 450,000 participants self-reported their coffee intake and were free from heart rhythm issues or cardiovascular diseases at the start of this research; they reported whether they preferred instant, ground or decaffeinated coffee as well as how many cups a day.

Researchers discovered that individuals who consumed two or three cups of coffee per day were significantly less likely to die over the course of the study than those who avoided it, as well as having lower risks of coronary artery disease, high blood pressure and heart-rhythm problems. The link held regardless of its caffeinated or decaffeinated content or how often people consumed one or more cups daily.

Studies examining only a subset of population have produced similar findings; other recent research shows the same thing. Studies have also demonstrated that coffee contains polyphenols – antioxidants which may reduce inflammation and protect against cardiovascular disease and Alzheimer’s. Beans grown at higher altitudes such as Ethiopia or Central/South America tend to contain higher concentrations. Brewing methods also influence flavor and nutrition with espresso and French press producing stronger cups than others.

Coffee should not replace other healthy food and beverages such as whole grains, fruits, vegetables, nuts and seeds – however a registered dietitian can assist you with creating a comprehensive approach to coffee consumption that maximizes its health benefits.

Caffeine may interact with medications you take, so it’s advisable to check the labels on them prior to beginning any new habits like drinking coffee. Caffeine has been shown to increase blood pressure, interfere with heart medications, affect mood and energy levels negatively and alter mood and energy levels significantly – for this reason if you have any medical conditions or take medications consult your physician first, while speaking to a registered dietitian can assist in finding ways of enjoying coffee while meeting all your health requirements.
