Dietary nutrition literature thousands of years of food culture history shows that the Chinese people's dietary habits as a whole, is on the basis of vegetarianism, and strive to meat and vegetables, a comprehensive diet. As the "Suwen - five often political theory" said "grain meat, fruit and vegetables, food and nutrition to the end of the" and "Suwen - Tibetan ware method of time" said "five grains for the support, five fruits for the help, five animals for the benefit of the five dishes for the full, the smell of the combined service to replenish the essence of the gas". The so-called comprehensive diet, that is, long-term or often in the content of the diet as diversified as possible, pay attention to meat and vegetarian, main and side dishes, meals and snacks, as well as food and drink, such as the reasonable mix between. Neither partiality, nor over-eating and waste of food. But on the other hand, for special people or patients, it is not advocated to adopt the same dietary pattern as that of normal people, and it can be done according to their different physiques, occupations, beliefs and illnesses, so that they can use diets according to their causes and recognize their illnesses. Nutrition, trace elements and human health are in full bloom, everyone wants to be healthy. The first thing you need to know is how to get healthy, and that's a very important question.

The accumulation of successive generations of experience, the modern scientific evidence, for the necessary conditions of health is now generally agreed, the first is the spirit (psychological) factors, to have a good heart, a dialectical materialism of thought, improve their mental capacity; the second is the nutritional status, nutritional knowledge, and strive to do a good job; the third is the level of movement, to be done without formality to do more exercise, labor is not completely equivalent to exercise, exercise, and the amount of exercise. Labor is not exactly the same as exercise. Insufficient exercise and lack of calorie consumption are important causes of diseases and sub-healthy states; and the fourth is medical conditions. The fourth is the medical condition. If you have done the above three things, you will still have problems and have to go to the doctor, and the modern medical condition is also a necessary condition to ensure your health. Any one of the four factors is not omnipotent, and the positive synergy of a variety of favorable factors should be sought at all times. Internationally, there is a popular saying that the three high diets (high protein, high fat, high sugar) have caused modern civilization diseases (cardiovascular and cerebrovascular diseases, cancer, diabetes and sub-healthy state). In fact, there are three low (low vitamins, low minerals, low dietary fiber) to blame. Many people do not understand these six elements of nutrition, of course, do not do a good job of nutritional balance, and even a lot of people will be nutrition and protein equals.

Nutrition is the means to make a strong nation (as in Japan) and the means to prosper a nation. In China, there are many peasants who got rich first, and who became sick and returned to poverty because of their wealth. The Chinese Nutrition Society has called for nutrition education to be implemented as a component of poverty alleviation. Mineral elements are one of the six major nutritional elements for human growth and development. Normally, elements whose daily requirement accounts for more than 1/10,000 of a person's body weight are called macroelements (e.g. calcium, magnesium, etc.), and those below 1/10,000 are called trace elements. The 14 essential trace elements identified by the World Health Organization (WHO) are zinc, copper, iron, iodine, alkali, chromium, cobalt, manganese, molybdenum, vanadium, fluorine, nickel, strontium and tin. The first three nutrients - protein, fat, starch, simply known as energy nutrition, then the last three nutrients - vitamins, mineral elements, dietary fiber can be referred to as functional nutrition, of which trace elements is the core, because it is not easy to get to meet the mineral The role of elements plays an all-encompassing role in human growth and development. From the construction of body tissues, repair, to physiological metabolism, to enhance immune function, and even have a direct role in disease prevention and treatment. Calcium is not only a body-building element, but also an indispensable element of physiological metabolism, many diseases are related to calcium deficiency. Chinese medicine said the kidney yin deficiency, kidney yang deficiency, are caused by calcium deficiency. Middle-aged and elderly people have the most kidney deficiency, and middle-aged and elderly people have the most serious calcium deficiency is consistent. Land animals, especially human beings, are in a state of calcium deficiency, especially Asians, calcium deficiency is the most serious. Again, the synthesis of hemoglobin requires not only amino acids, but also iron. When iron is deficient, hemoglobin cannot be synthesized.

Physiological metabolism is completed through the enzyme, enzyme active component center is often trace elements. Such as manganese is a component of superoxide dismutase, selenium is a component of glutathione peroxidase, molybdenum is a component of nitrite reductase, their activity is respectively by manganese, selenium, molybdenum elements to stimulate. Similarly, zinc, iron, copper, nickel and other elements have their own corresponding enzymes. None of the physiological metabolism will be normal in the absence of trace elements. In coenzymes or vitamins, trace elements play a doubly important role. For example, cobalt increases the activity of vitamins fourfold or even more. In hormones, they also play an important role. For example, iodine is involved in the synthesis of thyroxine and chromium enhances the sensitivity of glucose to insulin. In the carrier of genetic information - nucleic acids, also have their figure, such as manganese can activate the enzyme deoxyribonuclease, to ensure that the transmission of genetic information does not change. In short, due to the research on the relationship between trace elements and the human body step by step, life sciences have made great progress. Previously, incurable diseases with unknown causes have found their causes through the research on trace elements. The four major endemic diseases - goiter, Creutzfeldt-Jakob disease, macroglossia, and fluorosis - are all related to the shortage of trace elements. In addition, the high incidence areas of esophageal cancer, nasopharyngeal cancer and liver cancer are characterized by a clear geographical distribution, which is also related to the lack of certain trace elements in local soil and water. Trace elements in the protection of people's health and disease prevention and treatment, not dispensable, but pivotal. Of course, trace elements in the human body also need to be balanced, lack and excess are harmful and not beneficial. Therefore, understanding the situation of trace elements in their own bodies has been an important means of measuring and predicting health.
