Such are the certain physiological advantages which the predominant use of vegetable products are capable of offering. If one takes the pure energy-producing point of view, the superiority of the vegetarian diet becomes greater still. From the fine works of A. Chauveau, modern physiology has shown us that muscle, in working, consumes sugary materials. These are provided by ingestions of sugar in a natural state, of dextrine or of starch; for a less important part, the glycogen of the system may also arise from hydrocarbonated cords existing in the molecule of certain albumins. Therefore it is only in an infinitesimal part, due to the fibrine of meat, and to the small proportions of glycogen which it contains, that flesh diet intervenes in the direct production of kinetic energy.
The demonstrations which have been essayed, touching the muscular superiority of vegetarians, appear superfluous to us. Such experiments could only have a positive value if they were made on both series of antagonistic subjects, with alimentary powers of energy-producing equality.
It should be distinctly understood that the vegetarian does not profit by any mysterious forces. The habit of preferring to nourish oneself with vegetable foods, can, at most, or at least, favour the physiological integrity of the subject, shield him against disease and assure his revictualment with foods recognised as active and easily measurable.
One cannot leave alcohol out of the list of advantageous vegetable foods. In fact, provided one keeps to strictly limited doses, it may be included among the alimentary foods, on a footing comparable to that of sugar. If one knew how to use without misusing it, alcohol might become a daily food.
