So if I understand well, the only advantage of the vegetable broth over the raw veggies is for digestion problems, where the absence of fiber in the broth makes it easier to digest.
And I would also think that there is some chances that for the same amount of vegetable used, the broth will have a little less NPN?
Would the length of time used for making the broth be a factor? The less time, the less NPN in the broth, but yet a good amount of minerals in it?
