I agree with you, Graycat. I have noticed that the words "high fat" or "fatty food" actually seem to mean unhealthy foods to people. Half the time, "fatty food" actually means sugary food in reality if you ask someone to list the foods that they consider fatty foods. It's like the word fat doesn't literally mean fat to people anymore and I think most people don't even realize they are doing this. I was talking to an Egyptian guy for whom English was a 2nd language and he kept listing all these great Egyptian foods that were obviously extremely fatty and meaty and he'd end every description of these foods with "no fat, very healthy!" I think he had actually picked up on this tendency to equate the meaning "fat" with "unhealthy" and "no fat" with "healthy" through his ignorance of the language. But the rest of us are just ignorant period. Including your anthropology professor. He ought to go discuss his mistake with a linguistics professor.
