Snackwise, whose motto is, "It's all about healthier snack choices," is an online calculator that rates common snack foods. All you have to do is simply type in information from the label. From there, snacks fall into three categories: red - choose rarely, yellow - choose occasionally, and green - the best choice. It you don't have the snack in front of you, there is also a large database of snacks already falling into those categories. Snackwise's target market is kids, but if you've ever done some damage at a vending machine, you'll appreciate it as well. You have to sign up to get access to the full list of snacks, but right now there is a free 30-day trial so you can check it out.
Oh, and in case you were wondering: Teddy Grahams Minis (Cinnamon), green. Nature Valley Vanilla Yogurt Bar, yellow. Frito-Lay Harvest Cheddar Sun Ships, red.
