in the digestive system, they had nowhere to go. the only food fit for them was in the grasses. there wasnt a bunch of undigested food and thick mucus walls lining the GI tract. they didnt have a liver full of flukes or a pancreas full of pinworms. they werent poisoned by petrochemicals. they didnt depend on doctors to be their sole source on health issues. they didnt have their GI tract perforated by a raging candida infection that keeps getting fed like a prize weaner pig. in other words, contact with them from the internal lining of the organism was no different than contact with the external lining - the skin. as it should be. as it is, it is a mainline into the bloodstream. man has trained it to be so by keeping it acidic.
