"perhaps doing and eating what we want (to the extent we’re making choices) is more valuable than lower mortality and morbidity"

It seems more systemic to me. I go to my supermarket and decide to eschew snacks like candy or potato chips for dried fruit or the like. But even the dried fruit has extra sugar added to it. I look at the vitamins and such on some yogurts and there is very little healthy about them. Normal dinner type foods are loaded with sodium, cholesterol, saturated fat etc. Even when one wants to be eat healthy, it can be a trial, because so much food is loaded with junk, even "healthy" type foods.
