I’m not stating an opinion on BPA, just the incorrect and over use of the term “study”.
Frankly, I don’t care anymore about much of this. I’ve got “study fatigue”.
There are different types of studies; there are pre-clinical studies, clinical studies and observational studies. This was the latter. Scientists understand the strengths and weaknesses of all types of studies (and there are many sub-groups of the ones I mentioned). Chill.
