Their argument is sound for a number of reasons, but one way or the other it is a fact that, in reasonable variation, fruit can provide the full complement of all required nutrients in adequate quantities, remembering that the requirement for protein and fat are much lower than generally believed. Therefore, instead of being considered merely an accessory to conventional meals, fruit should be considered in its own right as a staple food. The advantages of a fruitarian diet are:
- It provides complete nourishment with the minimum of extraneous substances capable of 'silting' up the tissues.
- It is most easily digested, minimizing the energy required for digestion (which is substantial), thereby minimizing total food (kilojoule) requirements.
- It is palatable.
- It is easily obtained and easily prepared.
- It satisfies the appetite when sufficient has been eaten--fruitarians are always lean.
- Minimum but adequate protein is provided.
- Minimum but adequate essential fats are provided.
- Maximum energy is available from what is eaten, with only carbon dioxide and water, which are entirely nontoxic, as the by-products.
- It provides the body with adequate amounts of pure water.
- It results in a favorable alkaline internal state.
- Favorable intestinal flora predominate in the bowel.
- No constipation occurs.
- No auto-intoxication occurs.
- The body detoxifies itself.
- The blood is clean and low viscosity; there is good circulation with low blood pressure.
- There is the least wear and tear and the least "silting up" of all the body organs and tissues.
That fruit alone can ideally sustain human health and vigor, even without drinking water, indicates that it indeed provides the basis of man's natural diet. Further substantiation of this view is that there are about forty distinct anatomical, physiological and biological features of humans which show unquestionably that the human body is designed mainly for a fruit diet, notwithstanding the fact that, like all animals, they can survive less successfully on a wide variety of foods. These features range from natural fondness for sweet foods, jaw and teeth structure, salivary secretion, length of digestive tract, size of pancreas, stereo color vision and so on. In fact, in all these respects humans are practically identical today with the other higher primates in the wild which, whenever possible, live on fruit.
Evidence of the suitability of fruit as a staple food and not just as an accessory to the conventional diet is to be seen by observing fruitarians who live entirely on a wide variety of fresh fruit, and who display lean youthful bodies, low blood pressure, clear vision and unimpaired faculties, even with advancing years. A well-known human peculiarity never before connected with this argument but which provides almost conclusive evidence is that humans, like all primates, are incapable of making vitamin C in their bodies, whereas other animals can (excepting guinea pigs and fruit-eating bats). Basing their argument on this fact, it is strongly advocated by many authorities that people should take large amounts of supplementary Vitamin C to compensate for this "error of Nature", which they put down to an unfavorable mutation in our evolutionary past some millions of years ago. To prove this "unlucky mutation" argument completely wrong, and at the same time prove that man is a natural fruit eater, consider:
- The only mutations which persist to become a universal feature of a species are favorable ones. Unfavorable mutations cannot possibly do so.
- A genetic change preventing the synthesis of vitamin C in the body, to become universal to an entire species, must therefore have been, at the time, a favorable change.
- The only possibility of such a genetic change being favorable is for the species to have been already getting more than adequate vitamin C, and that any more was undesirable.
- The only source of "excess" vitamin C in Nature is a diet of raw fruit. (Only certain tropical fruits contain such high levels of Vitamin C; many fruits contain only small amounts.)
Therefore it is clear that the human diet ideally should be based mainly on fresh fruit, and that past errors which have led to widespread vitamin C deficiencies are dietary--not genetic--errors.
