The 3 things I mentioned counterbalance each other. And also notice I didn't say we should get rid of science or scientists. I said we have gone too far in the other direction of disregarding "Joe Schmuck" (or granny), which your comment demonstrates.

Also there are lots of Joe Schmucks that know better than a so called "nutritionist" that a steak is better than an Oreo. Not all Joe Schmucks, but a lot of them.
