التغذية الصحية وفوائدها

Nutrition is the science that explains the relationship of food with the activities of living things. This includes eating food, eliminating waste products, release of energy from the body, and synthesis processes. Food and drink provide a person with energy for all vital body functions, so that his temperature is fixed at 37 degrees Celsius, suitable for vital body functions, whether during wakefulness or during sleep. With the energy extracted from food, a person performs all his movement and thinking activities, whether this is reading a book or running in a race. Also, food provides a person with the materials his body needs in order to build his body and repair his tissues, and in order to regulate the work of his organs and systems. [1] The food we eat directly affects our health. A healthy diet helps prevent infection from some diseases and helps to cure other diseases. And any unhealthy or inappropriate meal increases the risk of various diseases that may affect humans. Eating consistent, balanced meals is the best way to ensure that the body receives all the nutrients it needs. And the best sources from which a person obtains his needs of all nutrients, vitamins, and mineral salts are fresh vegetables and fruits, in addition to fish, various types of meat, and dairy products.
