If we take hard science we are told that the double blind placebo controlled trial is the gold standard. Indeed when we are measuring a single agent in regard to effecting a specific health marker in particular such trials are indeed the gold standard However such testing tends to overlook, or to be unable to calculate how multitudes of factors work in concert to create overall health This is likely one of the reasons tht we do not see any type of controlled studies regarding diets. Too many factors, too many potential mistakes in individuals reporting accurately what they eat and perhaps too many variables in determining what healthy outcomes are
This is not to say science and researchers with both their use of controlled studies and population studies are not able to make valuable contributions and insights into how how certain mechanisms in the body tend to work But there are other fields of what is being called evidence here that is also worthy of consideration
