It's difficult to know how much confidence the conclusions of this review warrants. All of the evidence was assessed to be "low" or "very low certainty" by the researchers themselves, meaning the results could be unreliable. Also, even a small reduction in risk of common health outcomes such as cardiovascular disease and cancer could make a big difference at a population level.
Arguably it would be prudent to stick to World Cancer Research Fund recommendations, at least until higher-quality evidence becomes available.
