Ted Bittman and Food

A great talk from Mark Bittman (popular food writer and talented cook) speaking on Ted.com.
Some of what he says channels Michael Pollan's The Omnivore's Dilemma. (Pollan says it better.) And I vigorously disagree regarding his remarks of animals and methane gas. (Bittman needs to read Joel Salatin.)  But much of Bittman's remarks are right on, and gives one pause as to just what we're doing to our health via our mouths.
 
What do you think about his remarks?
