The raw food hype is nonsense. There was a German writer I think her name was Barbara Ruetting she advocated to throw out pots and pans. As far as I know fro all the raw food she ate she died very early of cancer.
I do not tell that raw food is unhealthy but only raw food is unhealthy.
The only thing I can think of is that fermented foods are bad for your teeth because of all the acid they contain and I think you should eat them together with other food rather than snack on them between the meals. (Which is not healthy anyway)
What about the salt? A Chinese guy told me that there is a region in China were they eat a lot of salted vegetables (like kraut) and there is a high incidence of stomach cancer.
