I find takes like this to be true in the specific details but wildly wrong as a big picture takeaway. A lot of people are citing their favorite quotes here, so here's one of mine from the Relativity of Wrong by Isaac Asimov:

>When people thought the Earth was flat, they were wrong. When people thought the Earth was spherical, they were wrong. But if you think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together.

So I think there's a relativity of wrong problem that you run into when suggesting it's all just so complex and leaving it at that.

I would nevertheless absolutely agree that nutrition science and communication around it has been disorganized, contradictory, and without much in the way of a north star or a reliable "vanguard" of communicators representing a firm consensus. I feel much better about public communication from, say, astrophysics, archeology, geology, etc. and I think there's a characteristic degree of stability of knowledge particular to each of those fields.
