HUMAN BEINGS Human characteristics are in every way like the fruit eaters, very similar to the grass eaters, and very unlike the meat-eaters, as is shown in the table below. The human digestive system, tooth and jaw structure, and bodily functions are completely different from carnivorous animals.
As in the case of the anthropoid ape. The human digestive system is twelve times the length of the body. Our skin has millions of tiny pores to evaporate water and cool the body by sweating; we drink water by suction like all other vegetarian animals; our tooth and jaw structure is vegetarian, and our saliva is alkaline and contains ptyalin for predigestion of grains. Human beings are not carnivores by physiology – our anatomy and digestive system show that we must have evolved for millions of years living on fruits, nuts, grains, and vegetables.
