Oh dear, it just came to me that I had margarine in my childhood during WW2 and after because butter was limited. My wife remembers my mother saying to her in the 1960s - I hope you don't give him too much best butter.
It is actually worse than this. Any study that uses two diets that don't have the exact same base diet are not real science. In real science - we only change ONE variable. If you have two research diets - often from two companies - the base of the diet is not the same - thus multiple variables.
This is a failure even at high-school level science - high fat diets that have added sugar and no fat - (vegetable oils are not 'fat') - the rule is garbage studies - not science.
You don't have to read much to note the absurdity.
