A mix of my parents and Sesame Street, but I remember as a kid it was so much fun to try and eat a rainbow every day! I remember there being a lot of emphasis in the different colored fruits and vegetables that should be incorporated into a diet, and the more colors you ate every day, the more varied nutrition you were getting. Even as a kid I didn't I think this was foolproof or anyting, but I had a little marker board to record all the colors of foods that I ate that day and I used to think it was so much fun. I want to parent my kids the same way someday :)
