Not long ago in a comment he said that by its very nature, an evil food and medicine lobby and the expulsion of vitamins. But now, I'm going to attack and expel vitamins now. In more than one section, because once we have a topic, let's be thorough.
The XIX. At the end of the century, it became apparent that certain diseases were caused by the absence or surplus of nutrients. The golden age of research in this area is the 20th century. It was the first half of the century, knowledge of deficiency states expanded rapidly, and the theory was well acknowledged by the practice: by reducing the quality of hunger, the public health situation has significantly improved. The XX. We got to the second half of the century that classical illness-related illnesses disappeared in developed countries, and today we are only dealing with types of deficiency disorders in people with extreme diets. One of the key factors in improving the quality of life and life expectancy was the effective eradication of these deficiencies, so a point for Gryffindor is modern medicine.
In the light of the discovery, he was given the opportunity to classify these vital organic substances into a separate group, and only a good name had to be added. Since today, B 1 is known as a vitamin substance (thiamine) they found nitrogen (i.s. chemically classified in Group amine name), and it appeared that the organic compounds are life ( debate - Latin word) are indispensable, so named them vitamin. The vitamin name sounded very well and gained popularity in the public speaking that it was inadvertently immersed.
In the case of vitamins, there are two batches to be met: first, the substance must be taken from an external source (food) because the body is unable to produce it. Secondly, that substance must have an important biological function in the body. In the case of current vitamins, there are problems with both criteria.
Nor is it a common common feature that the body is unable to synthesize, since Vitamin D is actually produced by sunlight, and the amount of nutrition is insignificant (normally). If we consume enough carotenoids, there is no deficiency in vitamin A (retinol), there is no need for direct retinol intake.
However, there are still a few organic compounds that are not classified as vitamins but the body cannot produce them and deficiencies can cause serious health problems: neither the essential fatty acids (linoleic acid, alpha linolenic acid and their derivatives) nor the essential amino acids are vitamins , while in the latter there is still nitrogen. So this criterion has also fallen.
Foam on the cake: Many vitamins do not contain any nitrogen, so no vitamins. Nitrogen-containing compounds are essentially grouped in vitamin B, but chemically, this team is also strongly mixed, and overall, the presence of nitrogen is a feature that does not play a role as a vitamin. In itself, therefore, the vitamin word should have been removed very quickly from the market as a misleading concept.
At the beginning of the vitamin era, all the identified vitamins had a well-identified deficiency disease (A - puffiness, B1 - beriberi, C - scurvy, D - rachitis, B12 - large cell anemia, B 5 - pellagra etc.) , folic acid is not a typical deficiency in fetal age, it is no longer in adulthood. For most vitamins, there are strongly different effects from the type of deficiency, eg. vitamin A deficiency can also cause bone development, as we know about the growing risk of vitamin D deficiency, and the same symptom may be associated with a lack of vitamins and trace elements.
