The Weight Watchers points system (the older one) was essentially trying to solve this. Points are essentially calories divided by 50 (with adjustments to emphasize low fat and high fiber) and are easily memorizable. It doesn't matter exactly which bread you ate, because it's probably 1 point per slice anyway. (I don't know much about the "new" points system. I think there are a lot of things that are just 0 points.)
