Coffee is enjoyed by millions of people every day and the ‘coffee experience’ has become a staple of our modern life and culture. While the current body of research related to the effects of coffee consumption on human health has been contradictory, a study in the June issue of Comprehensive Reviews in Food Science and Food Safety, which is published by the Institute of Food Technologists (IFT), found that the potential benefits of moderate coffee drinking outweigh the risks in adult consumers for the majority of major health outcomes considered. Researchers at Ulster University systematically reviewed 1,277 studies from 1970 to-date on coffee’s effect on human health and found the general scientific consensus is that regular, moderate coffee drinking (defined as 3-4 cups per day) essentially has a neutral effect on health, or can be mildly beneficial. The authors noted causality of risks and benefits cannot be established for either with the research currently available as they are largely based on observational data. Further research is needed to quantify the risk-benefit balance for coffee consumption, as well as identify which of coffee’s many active ingredients, or indeed the combination of such, that could be inducing these health benefits.
There is a scientific consensus that regular and moderate drinking of coffee would exert a neutral or slightly beneficial influence for adult consumers rather than bringing huge potential risks, but it should be noted that current research is based primarily on observational data, with further research needed to confirm and quantify the result of current findings.
