The potential benefits of moderate coffee drinking outweigh the risks in adult consumers for the majority of major health outcomes, an extensive scientific review has found.
The review was carried out by researchers at Ulster University and published in the June issue of Comprehensive Reviews in Food Science and Food Safety, which is published by the Institute of Food Technologists (IFT).
The researchers 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 review was used to create an exhaustive list of the potential health benefits and risks of coffee consumption on total mortality, cardiovascular disease, cancer, metabolic health, neurological disorders, gastrointestinal conditions, and other miscellaneous health outcomes.
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.
Some financial support of this study was provided by Italian coffee roasting company illycafe s.p.a., the authors claimed no conflict of interest regarding the objective search and summary of the literature.
