Is there an alternative that isn't as salty? Every time I've tried it (which is only a couple of times) I've found it incredibly salty :/
For some definition of "fine", at any rate. Outside of groups like the Inuit who eat a lot of organ meat to compensate, we don't have a great idea of what sort of long-term nutrient deficiencies you may accrue by eschewing all fibre and carbohydrate-based foods.
