I've recently started tracking my foods on fitday. The only problem is, I use a lot of homemade stocks in my cooking and as a snack in and of itself. The closest thing I can find on fitday is something called "chicken broth, without tomato, home recipe", which lists 8.5g carbs per cup. I can't quite figure out how boiling bones (with cartilage and a bit of skin) in water leads to any carbs, so I doubt the accuracy of the rest of the info.
Anyone have any leads on where to get accurate info for homemade stock that is literally boiled bones?
