If you haven't heard about this act, you should definitely look into it. I encourage you to sign the petition as well. Here's the platform:
We believe that federally funded nutrition programs should provide all children with the healthy food they deserve. This includes low fat and safe dairy, fresh fruits and vegetables, and whole grains. Schools should be soda and junk-food-free zones and serve food that complements and furthers parents' efforts to feed their children healthfully.
I believe this is definitely worth getting behind! Take action today!
