Eating sundried clay every so often is, imo, essential on a RVAF diet. Not all the time, obviously, just on rare occasions, but, even on the most perfect RVAF diet possible, there will always be circumstances where one eats something not right/healthy for one, maybe a raw oyster affected by the red tide/algae phenomenon or whatever, or maybe one hasn't done enough exercise and the clay might help with some resulting bodily toxins/wastes that have accumulated etc.. I discount clay in terms of a need for any nutrients, I just see clay as a useful, necessary detoxing susbtance to be used occasionally, perhaps once a year or so for a RVAFer(or more frequently if toxic foods such as cooked foods/poisonous mushrooms etc. are ever consumed).
