Various experiences and statistics have clearly shown that ingested food has a significant impact on the health of the individual. Many diseases are caused directly or indirectly by poor nutrition, and often it is enough to correct unhealthy eating habits to regain good health. Even the disturbances caused by polluted air, cold, a strong emotional state, etc. they do little harm to a person who feeds himself according to his physiological needs, especially if he is in good health. The main cause of tooth decay, now so widespread, is to be attributed to the consumption of refined cereals and white sugar. Foods rich in unsaturated acids (they contain a lot of the fats of animal origin), the "potable" water with chlorine and the lack of sun baths are the primordial causes of the excess of cholesterol in the blood.Following an exclusive diet of refined cereals (white bread, polished rice, etc.) in a short time, painful and bleeding gums, as well as pellagra and beriberi, occur due to deficiencies in vitamins. A poor or iron-free regime causes anemia. Calcium, silica and vitamin D deficiencies lead to severe decalcification throughout the body, with deformation of the spine, flat feet, decayed teeth.He who consumes products rich in potassium and low in magnesium prepares the ground for cancer. Those who eat very few raw foods are easily subject to infectious diseases. A menu without vitamin E causes infertility. A strict macrobiotic diet, based almost exclusively on the consumption of unpolished rice, can easily cause scurvy, anemia, hypocalcaemia (poor presence of calcium in the blood), kidney dysfunction, etc.After various positive experiences, prof. Benjamin S. Feningold states, without a shadow of a doubt, that in-fear aggression, the causes of which for many are inexplicable, is instead due to the chemical additives added to food substances. These chemicals (especially those of color and taste) act on the child's brain, with the same effect as the drug: they block the inhibitory brakes freni. Health is to be considered normal; the disease is a reaction of the body to restore the balance of the organism invaded by evil. The disease does not affect us by fatality. Any kind of diseaseis drawn to ourselves with an irrational way of life. It is ridiculous to drinkalcohol, smoking, overeating, ingesting devitalized substances, etc. and then ask the help of God or the doctors to get rid of the evils that torment and destroy us. Less prayers, ceremonies and philosophy and more practice of justice, and in this way we will have the opportunity to understand what are the laws (which require respect and love towards every form of life) that govern this planet.
