That's a pretty biased and inaccurate scoring system though. It would be more useful if it were in more detail and included things like grains, fruit juice, processed foods, vitamin pills, soy. As well it doesn't allow you to choose organic for all categories. There is such a thing as organic milk.
I'm not positive, but I think the organic question applies to all the food categories. Whole grains were included. I agree with you that processed foods definitely should have been taken into consideration. Also, the amount of food that you get from local producers should also be taken into account. It's an interesting little tool, even if it doesn't take EVERYTHING into account.
