We survive in the era, 60, 70 after catching a brief period of hunger, malnutrition, later days, rarely hunger experience, but in big cities, malnutrition still exists, anorexia, more than obesity, headache for doctors, anorexia, have hunger? Anorexia (individual thinking): in the absence of learning to think rationally about what is beautiful? Before there is the ability to think rationally has been implanted deep inside, lurking like a ghost, waiting for the opportunity to move. So much so that she can’t tell why when she has an attack. Could this be the legendary subconscious mind? The following are the changes in the body after malnutrition in nutrition textbooks: 1. anxiety and depression in adults. 2. Decreased muscle strength and endurance. 3, the heart muscle weight becomes smaller, the inner diameter of the ventricle (heart chamber) becomes smaller. 4.Renal blood flow slows down and filtration rate decreases, etc. 5.Decreased diaphragm weight and reduced respiratory function. (e.g. a patient with chronic obstructive pulmonary disease has respiratory failure, nutritional support cannot keep up, reduced respiratory muscle function and quality, and difficulty in evacuating the respiratory muscles.) 6, gastrointestinal function: small intestine absorption area is reduced, gradually occurring to fat, glucose absorption disorders, gastric juice, pancreatic juice, bile secretion is reduced. 7, impaired thermoregulatory ability in response to cold, easily leading to hypothermia. 8.Decreased immunity. 9.Poor wound healing ability. 10.Lack of pleasant mood. These conditions may initially originate from the spirit, or from deep within. But once they occur, they can backfire on the spirit: anxiety, depression, and lack of pleasurable experiences.
