Quinoa, tofu, sushi, hummus, wine and shrimp were deemed to be healthier by experts than by the public.
The reason, according to FDA research, might be that these foods have only become part of the mainstream American diet relatively recently, and people may not be aware of their health benefits.
Other differences in opinion could be due to mixed messages in the media about healthy and unhealthy foods. For example, there are conflicting ideas about alcohol: while some believe moderate drinking has some health benefits, it's not clear where the line is between moderate and excessive consumption of alcohol.
