I can't attend, but if any of you Boston-area Groks have $5-10 to spare, you should attend this symposium: The Harvard Food Law Society Presents: 2013 Forum on Food... - Eventbrite

I wish I could go, but I have a family engagement. It sounds very, very interesting. Here are the details:

As a part of the Harvard Food Law Society's mission to foster dialogue and exchange knowledge of emerging issues in food policy and regulation, our second annual conference will explore the legal and policy aspects of food labeling and its effects on consumer knowledge, choice and behavior.
Our forum will bring together a host of authorities on food law and policy to raise discussion on a number of pressing questions, including: What should we know about what's in our food and how it is grown? What considerations should inform these decisions? Are food labels a meaningful tool to encourage better nutrition choices?
