It's "good" that this is in Nature, but does any health-aware person not already know this? Our real problem is that most people aren't health-aware, and advertising (including the pharma-funded healthcare system) absolutely overwhelms common-sense truths about health. Over the past few years I have improved my own health by greatly limiting my intake of sugars, including by cutting out "healthy" smoothies, but I learned all this from Dr Internet, and NOT from any physician who was being paid to treat me. US physicians' knowledge of nutrition is stuck at whatever they were taught in med school, which was probably 20+ years behind the research at that time.
