Chromium other trace elements.
Chromium is a mineral that has become widely known because of its ability to normalize serum glucose.
In the late 1950s, two researchers, Schwartz and Merz, reported that rats in which artificial chromium deficiency was artificially created in the diet developed intolerance to sugar; when chromium was added to the diet of “Diabetes-like” rats, their condition returned to normal. This was the first confirmation that chromium is necessary for animals for a normal life. Since then, researchers have realized that chromium plays an important role in human metabolism.
Since the concentration of chromium in most types of foods is too low to affect the concentration of sugar in the blood, many nutritionists recommend that their patients supplement the diet with chromium supplements.
The positive effect of chromium on insulin sensitivity plays a key role in the treatment of depressive conditions accompanied by a pathological burden to the consumption of carbohydrates. The additional intake of chromium has a positive effect on pathological disorders of appetite, decreases the craving for carbohydrates and normalizes libido. Chromium supplements are usually well tolerated and do not cause side effects.
Chromium is an integral part of the low molecular weight complex - glucose tolerance factor (GTF), which facilitates the interaction of cellular receptors with insulin, thereby reducing the body's need for it. The tolerance factor enhances the action of insulin in all metabolic processes with its participation. In addition, chromium is involved in the regulation of cholesterol metabolism and is an activator of certain enzymes.
Scientists from the Beltsville Research Center (Beltsville research center) associate the effect of this element on enzyme systems with the fact that chromium triggers the reaction of attaching phosphorus-containing molecules to insulin receptors, which, in turn, provides maintenance of glucose to cells that need energy.
When the hormone finishes its work, another enzyme enters into effect and “disables” phosphorus-containing molecules from insulin receptors. Thus, their activity ceases. Reduced insulin secretion and concentration in the blood leads to the mobilization of energy from the depot (liver, muscle, adipose tissue) while reducing food intake.
This trace element is so important for sugar tolerance that its severe insufficiency leads to the development of diabetes-like disease.
The level of chromium decreases during childbirth and after birth, in children with diabetes, with coronary arterial disease (hardening of the arteries leading to the heart). Chromium deficiency during pregnancy can explain diabetes, which then develops (diabetes during pregnancy), and a violation of chromium-insulin interaction can also contribute to rapid weight gain, fluid retention and increased blood pressure that some women experience during pregnancy and after childbirth .
Recent studies have shown that the amount of chromium in any additives may not be as important as the chemical form of the element itself. So it is established that only trivalent chromium takes part in biochemical processes.
According to a study conducted in Ohio (USA), the absorption of various forms of chromium is different. Only chromium picolinate (picolinate) is well absorbed by the body. The experiment proved that when used in this form absorbed about 40% of this element. The absorption of other chromium compounds is insignificant and is approximately 1%. Chromium absorption from food is less than 10 percent.
Of all the variety of products, "broccoli" is the richest source of chromium. One serving of “broccoli” contains 10 times more chromium than the same amount of green beans, potatoes, or orange juice, although the concentration of this element in plant foods is an order of magnitude less than its concentration in mammalian tissues. Particularly high chromium content in brewer's yeast, in addition, it is present in meat, liver, legumes, whole grains, bran.
Unfortunately, chromium is poorly absorbed, especially from products subjected to intensive heat treatment. Moreover, the abundant consumption of carbohydrates stimulates the process of removing chromium from the body. A modern man who adheres to a diet rich in refined sugar needs more chromium than, say, fifty years ago. It should be noted that now people not only consume less, but also lose more chromium.
Many supplement manufacturers seek to make their product non-toxic, convenient for production and chemically stable (capable of long life on pharmacy shelves). It also gives preference to ingredients that can easily be given the form of tablets for ease of use.
This last consideration prompted the manufacturers of multivitamin-mineral supplements to prefer chromium chloride, the molecules of which differ in small size. People do not want to take ten pills a day or swallow one pill, shocking them with their large size. The problem is that it is chromium chloride that is absorbed worse than all its compounds. In the experiment, a dozen women took 200 micrograms of chromium in the form of chromium chloride, which led to an increase of only thirty percent of the chromium in their organisms compared with their usual diet.
The use of chromium nicotinate (Chromium nicotinate), known as GTF, is used as an agent that enhances glucose tolerance (this drug has gained wide commercial fame in recent years) doubles the level of chromium consumption. Preliminary studies have confirmed that chromium nicotinate has a stabilizing effect on blood glucose.
However, according to DiSilvestro, these data may be the result of a violation of the method of chromium in the blood and the fruit of imagination. Ohio scientists studied a dietary supplement containing chromium nicotinate in combination with certain attached amino acids. It is established that such a compound is absorbed three times better than GTF.
But the best characteristics are noted nevertheless at chromium picolinate. In this compound, chromium is combined with picolinic acid (picolinic acid). Additives containing this compound increased chromium intake in subjects six times. It should, for the sake of fairness, be mentioned that these studies were funded by Nutrition21, a food supplement company that produces a food supplement containing chromium picolinate under the brand name Chromax.

Chromium other trace elements.
Trace elements should be added to the PP with the daily needs. However, the information available on this issue is clearly insufficient, since there are no well-defined doses of microelements for patients in intensive care units. However, a frequent micronutrient deficiency may be accompanied by some clinical manifestations and ultimately influence the results of treatment. Highly
- Physiological and hygienic assessment of essential trace elements.
Trace elements are chemical elements found in the tissues of the human body in concentrations of 1: 100,000 or less. To trace elements also include chemical elements in low concentrations contained in water, soil, etc. Some trace elements are absolutely essential for the vital processes of the human body, as well as for the normal course of many metabolic processes.

- Other sensations
Compared with vision and hearing, other sensations lack the rich functionality due to which vision and hearing are called "higher feelings." Yet these other senses are vital. For example, the sense of smell (smell) is one of the most primitive and most important of these sensations. Perhaps this is due to the fact that the smell penetrates the brain via a more direct route,
- OTHER STEROIDS
In the body, there are other steroids that can either be synthesized from cholesterol, or form simultaneously with it during similar chemical reactions. For example, bile contains steroids called bile acids. Their concentration in bile is 7–8 times higher than that of cholesterol. (Unlike the latter, bile acids do not lead to diseases, as well
