There seems to be an entire industry around extracting nutrition research from these deeply flawed self-reported surveys ... on the grounds that it's the best data we have. Which is like looking for your car keys under the street light because that's where the light is.

So while I sympathize with this story and think it shines light on the process of institutional character assassination, it's about replacing one set of non-probative data with another.

Did the paper here use the calorie data from the nhanes dataset? My (perhaps incorrect) understanding was that they used bmi which was measured rather than self reported?

I presume you relate this as a critique of self-reported data rather than a critique of the paper in TFA?

The article specifically mentions how all the datasets their study used were NOT self reported, but measured. It's one of the biggest arguments for why their study was more trustworthy and why the assumptions/accusations were spurious and baseless
