Human health in itself is nothing without filling, without maintaining it. One of the main ways to maintain health is nutrition. Balanced nutrition and health are inextricably linked.
Nutrition is one of the main factors in human life, affecting the state of human health, its ability to work, physical and mental development. In addition, the relationship of nutrition and health affects the longevity of a person.
The close relationship between nutrition and health was first noted in ancient times. The man understood that malnutrition negatively affects the development of children, adults often suffered from this and were weak. In the end, malnutrition led to early death.
In the seventeenth century, the British Admiral Anson, in a battle with the Spanish conquerors, did not lose a single soldier, but the scurvy that broke out on a ship scored more than eight hundred out of a thousand. As it turned out, vitamin deficiency is much worse than enemy weapons.
At the beginning of the twentieth century, after the delivery of refined sugar, flour and preservation to the Aleutian Islands, dental caries spread among young children. And after twelve years, almost all the islanders who ate refined foods had bad teeth. In the history of mankind, countless evidence of the relationship of nutrition and human health. Among other cases, the development of peptic ulcer, malignant tumors, diseases of the gastrointestinal tract and other systems and internal organs of the human body, associated with a lack of nutrients, vitamins and trace elements in the diet, is noted. Along with this, there are many examples of the opposite connection in history when normalized nutrition favorably affected health.
Eating disorders can be different. For example, with a carbohydrate excess, stagnation of fluid in the body is observed, leading to edema, pallor of the skin, increased consumption of vitamin B1. Lack of this vitamin leads to disorders of the central nervous system.
In addition, an excess of animal fats and a lack of vegetable fats can be observed in the body. To eliminate this violation, you need to make a little effort. Vegetable fats are a kind of building material for cell membranes, fibrous tissue, and are also included in nucleic acids. Polysaturated fatty acids remove cholesterol, contribute to increased elasticity of the walls of blood vessels. In addition, they perfectly support the protective functions of the immune system, protecting the human body from radiation. With a deficiency of polyunsaturated fatty acids, cholesterol plaques accumulate in the vascular walls, contributing to the formation of blood clots and neoplasms, and a gastric ulcer may develop on this soil.
Lack of fresh fruits, berries and vegetables is a more difficult problem. Studies aimed at analyzing the diet of residents of different countries of the world, found that vegetables are rarely eaten.
Unfortunately for humans, all herbal products are seasonal food. In addition, it is picky about the climate, and people often underestimate the benefits of vegetables.
For a long time, mankind has developed the basic rules of nutrition, consisting in the variety of food consumed, moderation in food and the timeliness of food intake. Unfortunately, the fast pace of life, accelerating even more every day, negatively affects people’s diet. The blame for this lies not only with the person himself, but also with the social system.
