> I would bet dollars to doughnuts in a few decades we will look at all current nutrition advice to something akin of medieval quackery. All current nutrition advice? Does this equally include the nutrition advice that your cousin gives on Facebook, as well as the advice given by doctors of nutritional science? I get where this skepticism comes from. Nutrition is complicated, and there's a lot of bad advice shared by random people you meet. There's also the diet supplement aisle at your local grocery store, which is full of poorly-regulated products with dubious claims. (At least, in the US, we have these. They are not regulated as drugs.) At the same time, nutrition-based interventions are some of the most effective public health policies we've ever implemented. In the US, we have programs like WIC. We have iodized salt. We cure blindness in children. We cure scurvy. These are all amazing things--things which we kind of take for granted, because we're not ever exposed to scurvy, childhood blindness, etc. This is not the first time I've heard such extreme skepticism of nutritional science and it just boggles the mind because if you talk to someone who works in the field, they have amazing success stories to talk about.
