I can’t help getting caught up in the arguments about school nutrition standards, particularly because I was quoted in an article about them in the New York Times last week.  I am very much of two minds on the subject:
On the one hand: My understanding is  that Senator Harkin thinks that his plan for school nutrition standards is the best that can be expected in  the current administration.  Will the next Farm Bill do something better?  I  have no idea.  So from a pragmatic standpoint, Harkin’s bill is worth  supporting.  It will get the worst foods out of most schools in most  places.
 On the other hand:  With that said, I  personally do not favor setting up nutrient-based criteria for deciding which  foods are in or out.  I think such standards are a slippery slope.  If you set  those kinds of standards, food companies will simply formulate products to slip  just under the cut points.  Does a gram of sugar make that much difference?  I  don’t think so.  My personal view is that schools shouldn’t sell competing foods  at all and that vending machines should be removed from schools.  Out!  Vending machines didn’t  used to be in schools and they don’t have to be there now.    But, as I like to explain,  I have tenure and I get to take principled positions on such  matters. 
Opinions, please!
