When nutritional epidemiologists conclude (as they always do) that some item of our diet or lifestyle associates with chronic disease, it’s inevitably news. Not so when methodologists point out potential, if not very disturbing problems with the epidemiology itself. This research has enormous influence on our conceptions of a healthy diet and yet the media tends to universally ignore its many problems.
Maybe this will help: welcome to the metaverse problem in nutritional epidemiology.
My latest post on substack is about another reason (as if we needed one) to be skeptical of this research.
