>Nutritional guidelines have very short lives compared to every other field of science. It's such a minefield of contradictions.

Like psychology. And I'm sure there are many other examples.

Nutritional science seems worse, but I think that's because real (not pop) psychologists seem to be giving up on simple good/bad and fad advice.

There is so much of this in nutrition because there is profit motive via the food industry.

Drugs are another industry. We will look back at SSRIs and benzos the same way we look at lobotomy now.

Only when we have much better things of course. Progress is being made.

The thing about nutritional science is that progress seems like it's just not being made at all. We go from fad to fad.
