Nutritional science has failed us before -- the low fat movement and the panic over salt. And then there's ye olde Food Pyramid which was marketing for Big Ag.

Another one was the concern of soy phytoestrogens, and claiming that only fermented soy was safe.

Much of this had some scientific basis, but science isn't perfect and evolves.

On the other hand, there's ideology and it rejects any scientific reporting that falsifies its beliefs. Science is about being falsifiable -- so when confronted with compelling evidence that earlier understanding is rejected and replaced with new knowledge.

RFK Jr. is an ideologue and is the worst person to be in the role he is. He may get some things right (food dyes, etc), but that's the broken clock effect.
