Nutritional biology is the absolute epitomy of how truly corrupt and moronic the system is.
It's actually quite remarkable how almost everything boils down to
'This popular scientist in the 60s said xyz therefore all research papers must conform to xyz to reach peer review'
And it's not small issues either. Literally all research on the causation between LDL cholesterol and blocked arteries are wildly incorrect.
Dietary effects on cancer growth, carbohydrate based inflammation and arthritis, carbohydrates and insulin resistance... All massively incorrect.
Life expectancy is literally 10 years lower across the board when averaged out because of this.
