Whether the findings have merit or not (I'm willing to believe its true), the sticking point is getting people to change even if that change will directly benefit them. As many things culture-bound, you have to start with the young, those already eating are mostly set on the ways and there isn't much of a chance to change them.<p>It's like changing attitudes toward education, spending habits, rules of society, racism, etc. We all will recognize what's better, but will have difficulty executing, either individually or as a society.<p>So, good news, but... how does it help people in practice?
