The relationship between diet and health Diet (also called "diet") refers to the food and drinks we usually eat. All food comes from plants and animals. People get all kinds of nutrients and energy needed to maintain health through diet. Reasonable diet and adequate nutrition can improve the health level of a generation, prevent the occurrence and development of various diseases, prolong life expectancy and improve the quality of the people. Unreasonable diet, excessive or insufficient nutrition will bring different degrees of harm to health. Overeating can lead to obesity, diabetes, gallstones, hyperlipidemia, hypertension and other diseases, and even induce tumors in China, such as breast cancer and colon cancer. It not only seriously affects health, but also shortens life expectancy. Long-term nutritional deficiency in diet can lead to malnutrition, anemia, deficiency of various elements and vitamins, affect children's intellectual growth and development, and reduce human disease resistance and labor, work and study abilities. Malnutrition during pregnancy can lead to miscarriage, premature delivery and even deformity. Food hygiene is closely related to human health. Bacteria, molds, toxins and toxic chemicals carried in food enter the human body with food, which can cause acute and chronic poisoning and even malignant tumors. In a word, a proper diet has a great influence not only on one's health and longevity, but also on the health of future generations. Therefore, only a reasonable diet can control the disease from the aspects of nutrition and hygiene. The relationship between exercise and health ① Regular exercise can enhance the cardiopulmonary function, make the heart contract and rise, increase the heartbeat and reduce the number of heartbeats; Increase vital capacity, increase gas exchange between lung and tissue, and promote the discharge of carbon dioxide. ② It can reduce the content of cholesterol in blood and increase the content of high lipoprotein cholesterol in blood. This substance can remove fat and cholesterol deposited in blood vessels, thus preventing arteriosclerosis, coronary heart disease, hypertension and stroke, and delaying the aging of cardiovascular system. ③ It can improve the function of nervous system, enhance memory, improve the flexibility of body reaction, keep the elderly energetic, and improve their physiological self-care ability and work efficiency. ④ It can enhance human immune function, enhance the adaptability of the body to adverse environmental factors such as cold and high temperature, and improve the body's resistance to various diseases. ⑤ It can improve the digestive function of human body, increase the blood supply of gastrointestinal tract, promote gastrointestinal peristalsis, increase the secretion of various digestive juices, and accelerate the digestion, absorption and utilization of various nutrients. ⑥ It can strengthen muscles, ligaments and bones, prevent muscle atrophy, joint stiffness and osteoporosis, thus maintaining a strong body, maintaining the elasticity of muscles and skin and the flexibility of whole body movement. In short, proper physical exercise and physical labor can promote human metabolism, improve human physiological function, enhance energy, enhance physical strength and prevent premature aging.
