Agreed as far as nutrition is concerned. Look at the cholesterol and fat-related "common wisdom" they promoted for decades: saturated fats bad, animal fats bad because cholesterol, etc. Meanwhile I looked at my biochemistry textbook where the biosynthetic pathway for cholesterol began with Acetyl-CoA, which means that almost everything can be a precursor for cholesterol in the organism, be it carbohydrates, proteins, sugars, anything. The corollary for this is that should you want to reduce your cholesterol levels, a more appropriate course would have been to lower your calorie intake and perhaps a strategy to block cholesterol reabsorption on the digestive tract (the enterohepatic cycle) than just seeking a "low-fat" diet. Today this perception was corrected, but it was sacred dogma for decades despite it conflicted with the basic facts of human biochemistry.
