Apples and Green Tea (IMAGE) Norwich BioScience Institutes Caption The Institute of Food Research has published a new study that adds more to the growing body of evidence that certain compounds found naturally in foods have specific effects that help prevent chronic diseases. They have uncovered a mechanism by which polyphenols in green tea and apples affect a key signalling molecule, which could explain other studies that have shown how polyphenol-rich foods reduce risks of chronic diseases.
