In this age of refinement, our teeth, which were made to last as long as our bodies, begin to decay before we are matured. Foods are ingested into our bodies instead of being digested. Public hygienists and technical bacteriologists work hard, trying to prevent such diseases as diphtheria, scarlet fever, tuberculosis, typhoid fever, and many other infectious and epidemic diseases, resulting from unclean food and water, and imperfect sewage systems. Even with the purest of milk, meat, and water, we can make a filthy garbage can of our intestinal tract by the ingestion of foods which do not harmonize chemically, the result being decomposition. Right here we have all the dangers of modern diseases and pus formation, resulting in appendicitis, phlebitis, ovaritis, cancer, Bright’s disease, and all the above mentioned diseases, without having to look further for the garbage can on the back porch or the sewage system in the yard. The waste products from our tables, and the excretions from our bodies would be less dangerous to health if the selection, combination, and preparation of our food were more natural. The excretions of properly fed animals are not so dangerous to our health; why should ours be? The hygienic rules as taught by the orthodox Jew in reference to the combination and preparation of foods are wise. He is not allowed to mix milk and meat, meat and fish, and many other articles of food which do not combine well chemically. The Jewish methods of killing animals and the preliminary preparations--such as the watering and salting of meats before cooking--are also more hygienic. They eliminate part of the toxins of the meat, which have been in close contact with the air. Since life and personal health are generally in charge of woman, the right place for every girl under eighteen or twenty years is at home or in school. No young girl under this age should be allowed to enter a profession, workshop, or business college. An occupation which by long hours of work over-develops a certain set of muscles and nerves before maturity, will produce an abnormal development and an unstable temperament. Co-education at this age is also harmful, the result being premature development, and elopement marriages, or arrested sexual development and extreme independence, or marriage and continual suffering, owing to physical defects and lack of knowledge of the care of the human body, and of domestic science.
