I agree that there is a big cultural factor here. I wish people focused on this more. So many people want to look at correlations like income:BMI that don’t generalize to other countries or cultures. Really what they expose are cultural and societal idiosyncrasies, much more than they expose that “cheap food is not healthy”. Of course, that is less appealing to an epidemiologist because the cause and effect is less clear and has much greater implications than recommending more exercise.
