What's causing the extreme increase in kids' food allergies?

Are you concerned about food allergies and why so many kids have them?  The food supply in the United States has been greatly altered since the late 1990's.  Sadly, many of the additives being sold in the United States are illegal in other countries due to the fact they haven't been proven safe for human consumption. 

Robyn O'Brien, former financial and food industry analyst, became very interested in studying the food supply when her daughter had a severe allergic reaction during breakfast one day. Check out this excellent video featuring a TED Talk by Robyn O'Brien and also sign up for the free Food Revolution summit.
