I think the problem is the exact opposite. It's easier to blame everything on some single, specific thing like high fructose syrup or saturated fat. If you eat varied and in moderation (and don't sit on the couch all day) then you wont be obese. But politically it's better to blame McD, Coca Cola, and friends than say "You're fat, and it's your own fault".
