Modern eating habits with a predominance in the diet of canned food industry, intermediate goods and fast food can be blamed for a sharp increase in the number of autoimmune diseases — multiple sclerosis, eczema, asthma and alopecia.
A group of scientists from the Yale University and the German University of Erlangen — Nuremberg argue that some of the blame exactly modern products that have passed the factory processing and canning.
According to them, the results of the study indicate that the excess content of the products processed salt can be one of the factors that increase the incidence of autoimmune diseases.
Canned food, fast food and semi-finished products are a significant source of sodium, a component of processed table salt.
A group of researchers publishing Canadian Medical Association Journal compared the amount of salt in foods 2124 networks such fast-food restaurants like McDonald's, Kentucky Fried Chicken and others. They found that the sodium chloride content in different products from different companies. Even in identical names of the goods of the same amount of salt can vary depending on the country where service is available.
In the U.S., the salt content of fast food products of more than two times higher than any parameters in other countries. While government health organizations in many countries seek to reduce the amount of salt in food, the United States government that is trying not to raise the issue. According to one of the participants in the study, physician Norm Campbell, this is inattention allows U.S. producers of fast food much overdo their products.
Many fat-free foods are supersaturated with salt to give them flavor. One packet of fat-free Italian salad dressing used in Kentucky Fried Chicken, contains only half a gram of fat and 15 calories, but the sodium in it and a half times more than in a traditional dish of this restaurant — fried chicken sticks.
Data Centers Disease Control and Prevention say that the bread is saturated with salt. Toasted garlic loaf of bread from the menu of Subway contains 1,260 grams of sodium, and that's not the meat and cheese, it's just bread. For comparison — the same amount of sodium in 14 slices of bacon.
How recycled salt causes autoimmune diseases
Researchers from Yale University have been studying the mechanisms of action of T-lymphocytes. These are the cells recognizing foreign agents such as viruses and bacteria.
In previous studies have examined the possible role of one of the varieties of these cells (Th17) in the development of autoimmune diseases.
New laboratory tests revealed the following fact: in the salt solution, the cells act more aggressively.
In a study in mice that received high doses of table salt, high concentration observed in Th17 cells of their nervous system that provoke inflammation.
The activity of these cells is associated with exacerbation of multiple sclerosis in humans.
Scientists have studied this effect at the molecular level.
The results demonstrated the ability of Th17 cells to release ten times more cytokines in saturated salt solutions. Proteins called cytokines by cells which "communicate" with each other.
Study co-author Ralph Linker from the University of Erlangen — Nuremberg, said: "The results — a great contribution to the understanding of the mechanisms of multiple sclerosis. They can suggest new ways of treating the disease from which there is not an absolute cure-all. "
The disease develops when immune system takes the myelin sheath of nerve fibers in the brain and spinal foreign substance.
As a result of immune cells from the purified myelin nerve fibers. This disrupts the conduction of nerve impulses between the brain and body, causing impaired speech, vision and functions of the vestibular apparatus.
Another study co-author named David Hafler suggested that nature was clearly not destined to immune cells attack the body's own tissues, so external factors clearly play a role here.
He said: "Diseases are not caused solely by genetic disorders or some environmental factors. Disease — the result of their interaction with each other. "
Hafler continues: "People were genetically adapted to living conditions in South Africa, where the salt in their diet was not quite. This is one of the reasons why because of the particular gene Africans are more sensitive to other salts. Today's lifestyle and eating habits involve a large amount of salt, which obviously leads to high blood pressure and possible — to autoimmune diseases. "
The next planned step of the scientific team — the study of the role of Th17 cells in the development of autoimmune diseases that affect the skin.
According to them, it would be interesting to find that patients with psoriasis may alleviate the symptoms of his disease, reducing the amount of salt in their diets.
Be that as it may, in their opinion, the development of autoimmune disorders is a very complex process that involves numerous genetic and environmental factors.
In using the useful salt
Bleached and processed table salt technology — a big problem. Salt is essential to health. It is most readily available non-metallic mineral in the world. Our body is not designed to absorb sodium chloride, because it lacks nutritional value. However, if the salt is rich in dozens of other minerals, such as pink Himalayan salt crystals, or if it is gray, like Celtic, then our bodies have benefited a lot.
Specialist Barbara Hendel says it this way: "These mineral components are identical to the elements of which our bodies are built. This is the primary elements of the ocean, where life began. Our tears are salty, salt is released during respiration. Chemical composition of our blood like seawater. From the very beginning in the womb, we are swimming in the "bag" filled with salt water. In the water, the salt breaks down into ions. They conduct nerve impulses that allow to think and move. Even such a simple process, like drinking a glass of water, employs millions of processes, which "command" ions. They are responsible for the acid-alkaline balance in our body. "
According to Hendel, mineral salts are useful. They saturate the body with mineral ions, which are necessary for the balance of all physiological functions, they help to maintain health and to recover. In central Europe, these healing properties of minerals have long been known. In the Polish town of Wieliczka hospital was hewn out of a block of mineral. Asthmatics, allergy sufferers and people with various respiratory diseases found that inhalation of air into the saline cave leads to the relief of symptoms in ninety percent of cases.
Barbara Hendel believes — rather the lack of minerals than the excess salt is to blame in causing health problems. Her point of view is shared by other professionals, such as David poppy Carron of Oregon University of Medical Sciences.
