Googling "problems with self-reporting in diet studies" gives a good listing of scientific papers for me. Of course such a search is screaming out "confirmation bias", but it is still useful I think. This[1] is one study that seems to cover what I was talking about, although I have not read it in full.
If you want to take a deep dive into a subject, search for a recent paper on the subject and as you read it the paper will reference other papers, especially in the introduction. Here is where you can find possibly a more relevant paper on the subject. Read that paper and repeat. Soon you will have a decent idea of what is going on in the field. Hard to do if you don't know the jargon and the mathematical methods though.
