Cellulose and other trace elements

Fiber can be considered the discovery of recent years, although learned about it today, just the same and some micronutrients, known many years ago, has recently been recognized as necessary for a life of substance.
It is recognized that they solve issues proper enzyme activity of proteins. The concept of "metal of life" was formulated in the name of their already famous book by Professor David Robert William from the University" SV. Andrew's in Scotland.
Minerals make up 4 % of the weight of our body. A half of this amount is part of the solid parts of the body: bones, teeth, nails, hair, soft tissues, the rest is in the blood, interstitial and intracellular fluid. 70-80 % of the weight is water.
We represent a microcosm, because in our body you can find almost all the microelements that are in the nature. But... in a very unequal quantities. About 96 % of the weight of the body are carbon, hydrogen, nitrogen and oxygen. In addition, a lot of sodium, potassium, magnesium and calcium.
Oxygen is associated for us with the impression of fresh air, and yet, most of all in our body it is 60 % of body weight. Carbon, coal, connected with the idea of ... combustion, furnaces; in the body it is about 17 %. Hydrogen is about 10 %, nitrogen - only 3 %, calcium - from 1.5 %to 2.2%, phosphorus - 0.8 to 1.2 %, other minerals - potassium, sulfur, sodium, chlorine and magnesium - only tenths and hundredths of per cent1. Iron and magnesium in the body 0,0003 %, copper - 0,00015 %, iodine - even less, only 0.00004 %and silicon, zinc, fluorine, lithium, selenium and other trace. And yet how important they are! For our bodies and our health, well being they are just as valuable as vitamins. We learned it recently.
In truth, only the age of computers has allowed to understand the role of microelements in our lives. It was impossible before. Today, we know that among all the elements that make up our body, there are at least 25 needed to maintain health, and 18 of them are absolutely necessary, the remaining seven William calls useful. Certain doses of each of them help to maintain health.
Dr. Melvin that is, the page (USA) briefly defined the role of microelements: "this is food for endocrine glands, or, more accurately, for enzymes. In short, "metals of life." The effects on the body trace elements are connected; our needs in these metals individual. The body, for example, may not recognize some trace elements due to improper metabolism or diseases of the digestive tract.
Of course, in the environment and in food products has elements of junk. They can be divided into two groups. The first will be those elements in very small quantities necessary for the organism, and in large - harmful; in the other ones anyway (as a foreign body) toxic, and, therefore, harmful.
