Please, just for me, please go to see “Fed Up,” the new documentary that Katie Couric pitched to producer Laurie David as “the ‘Inconvenient Truth’ for food. I have several reasons for desiring this, but foremost among them is:

Doesn’t everyone know this already?”

The answer must be “no,” of course, for why would Couric, David, and director Stephanie Soechtig put all that stuff in there about the ill health effects of processed sugar, and the brutality of Big Food’s protectors, and the human toll that obesity brings to those who have it and their families.

So please go and tell me: You knew this already, right?
