This is a welcome idea. Related, has anyone ever used the Cronometer app to track all their food intake? MyFitnessPal is similar except that Cronometer has a very clear listing of where you're at with your daily micronutrient needs given the food you've eaten. It's pretty cool to see that you're not getting enough of some micronutrient and then go and consume some food, track it in the app, and see that you're now where you need to be.
