I don't know. It's too early to decide. Food science is really hard. You don't have any good measurements, just questionnaires and people lying in them or completely miss-judging their consumption.

There are some exceptions but even then (ward experiments, controlled feeding studies, etc.) you often have very low number os participants and other limitations.

They've done pretty good studies with rats and mice I believe. I think that htey discovered that the best foods to make them obese were the ones that are recommended for a healthy diet for humans!
