Fear the Nutrition Guru Whose Opinions Don't Change
Nutrition is anything but a set-in-stone science. It's staggeringly difficult to study as it's near impossible to control for the myriad of confounding variables that might influence outcomes, study durations are too short, and dietary self-reporting is abysmal.
As a consequence attitudes and opinions change.
It's not an academic crime to have a mind open to change, on the contrary, it's an academic crime if you don't.
