here's what he says about this great infographic:

In a nutshell, I was really inspired by the diversity and nutritiousness of the crops planted in the White House kitchen garden this spring and thought it would be eye-opening - not to mention jaw-dropping - to see what the White House garden would look like if it were planted to reflect the relative importance of the crops that are taxdollars are actually supporting.  

You'll see that there's very little resemblance between America's Kitchen Garden and our "Subsidy Garden" 

I don't know how useful this is, but feel free to download it, use it and share it as you wish. The data comes from the Environmental Working Group's amazingly comprehensive and searchable Farm Subsidy Database: http://farm.ewg.org/
