The genetically modified organisms can be defined as organisms genetic material (DNA) which has been modified in such a way that is not possible in nature. Used for this technology is often called "modern biotechnology" or "gene technology", sometimes "recombinant DNA technology" or "genetic engineering." It allows you to transfer specific genes from one organism into another, including between non-related species.

Such methods are used to create genetically modified food crops.

What are the GMF?

GM foods have begun to develop and supply the market, because there are perceived benefits of these products for both producers and consumers. It was assumed that they will be sold at a lower price and, moreover, will be better in terms of shelf life or nutritive value. Initially GM seed producers would gain acceptance of its products by food manufacturers, and focus on innovation that had to evaluate the farmers and the food industry as a whole.

The very first aim of the developers of GMOs was more effective protection of crops. GM crops, the products of which are currently on the market, mainly focused on strengthening the resilience of plant diseases caused by insects or viruses, as well as their greater resistance to herbicides.

Resistance to the action of insects is achieved by introduction of food crops produce a toxin genes of the bacterium Bacillus thuringiensis (BT). This toxin is currently used as an insecticide in agriculture, and is safe for humans. It is proved that GM crops that permanently produce this toxin requires less insecticide in some situations, such as when a lot of particular pests.

To increase viral resistance in plants is introduced genes of some viruses that cause plant diseases. This makes plants less susceptible to diseases caused by these viruses, thereby achieving higher crop yields.

To achieve greater resistance to herbicides in plants introduced genes of bacteria that provide better tolerability of some herbicides. At a time when the weeds are actively growing in particular, the use of modified crops thus led to a reduction in the amount of herbicides used.

How does the evaluation of the quality of GM products from traditional foods

First of all, most consumers consider that traditional foods (those that people ate for thousands of years) are more secure than the GMF. Change some of the characteristics of the foods often causes some concern, but the authorities do not always seek to carefully check the quality of the changed product through a variety of methods for risk assessment.

However, with the appearance of GM foods in most countries the authorities found it necessary to conduct a thorough evaluation of their safety. Have set up special systems to assess how safe GMO and GMF on human health and the environment. In relation to traditional foods are typically used much less rigorous methods of control. Thus, there is a substantial difference in the evaluation process for the two groups of food.

How is the potential risk to human health

Evaluation of food safety usually focuses on the following aspects:

• a direct impact on human health (toxicity)
• allergenic foods;
• presence of specific components, which have nutritional or toxic properties;
• stability of the introduced gene;
• nutritional effects associated with genetic modification;
• any unintended effects which could result from the introduction of foreign genes.

GMP and the risk to human health

Allergens. The introduction of genes of organisms that are common allergens, it is not recommended, except in cases when it is proved that the proteins introduced gene is not allergenic. Allergenicity of most on the market today GMF is not higher than that of many traditional products.

Gene transfer. Gene transfer from GM foods to cells of the body or to bacteria of the gastrointestinal tract can be unsafe if the transferred genetic material adversely affects human health. This is especially true if transferred genes resistant to some antibiotics Antibiotics - whether they will help you in the foreseeable future? . Although the probability of such transmission is low, permanent measures are taken to reduce the risks associated with gene transfer.

Hematogen, all known dietary supplement was first invented in the late nineteenth century when the medical community was found that iron is a part of the blood, pharmaceutical companies en masse began to develop numerous blood products, and iron. One of the results, in addition to liquid medicines on the basis of the blood of livestock, became hematogen released in Switzerland in the nineties of the nineteenth century, and appeared in Russia after the 1917 revolution.

What hematogen

Clearly define accessory hematogen to a class of drugs or dietary supplements (dietary supplements) is not possible, on the one hand, the pharmacological effect hematogen long studied (in particular, it is known that hematogen, as a preparation based on blood and iron, becomes an effective drug for anemia) and, on the other hand, today there are many other, much more effective for the treatment of anemia, therefore, can be considered as hematogen and Bud. In addition, solely by virtue of the modern tax legislation hematogen sell under the guise of the drug rather than a dietary supplement, much more profitable to producers. Whatever it was, the use hematogen certain: it contains the entire "collection" of nutrients - proteins, fats and carbohydrates.

In fact hematogen a drug is produced from a dry-treated cattle blood with the addition of a number of ingredients that improve its taste: unique, but pleasant taste hematogenically provide honey, condensed milk, ascorbic acid, or additives such as coconut or chocolate chips, nuts. Due to the main "ingredient" hematogen, the blood, the drug becomes an excellent source of iron, necessary for the formation of erythrocytes (red blood cells). For the formation of red blood cells needed hemoglobin - iron-containing protein.

Benefit

Hematogen useful as a restorative, preventive agent, and as an adjunct in the treatment of a number of quite serious diseases .  First hematogen regular use helps to normalize metabolic processes and the natural process of blood by increasing hemoglobin in the blood .  In addition, a protein composed of hematogen - a full source of all amino acids necessary for normal functioning of all body systems, and the ratio of these amino acids in the optimal human hematogen .  Finally, hematogen stimulates the absorption of iron in the intestine, thus making up for the lack of this trace element in the body .  Moreover - hematogen regular use of a beneficial effect on the skin, stimulates the growth of hair and nails due to the high content of vitamin A part of hematogen .  This vitamin is useful not only for healthy skin, hair and nails, but also to improve vision .

Hematogen as a drug, not a preventive agent useful in anemia associated with iron deficiency in the body, various eating disorders that lead to nutritional deficiencies and chronic diseases accompanied by hemorrhage (these include, for example, duodenal ulcer and gastric ulcer ).

Contraindications

Although hematogen - the preparation, by and large, natural, it has a few contraindications. In the first place, it can not be used hematogen allergy to any component of the formulation. Not recommended to use the product under various carbohydrate metabolism disorders and anemia due to iron deficiency is not, and other factors. Finally, it is not recommended to use hematogen when obesity and diabetes, as part of this drug contains a large amount of digestible carbohydrates that could trigger a sharp rise in blood sugar levels Blood sugar - a very important indicator . No side effects have practically no hematogen - in rare cases, in excess of the daily value hematogen may experience diarrhea or nausea.

How it works

Hematogen - a drug that contains iron, and stimulates the formation of red blood cells - red blood cells. Iron is a part of red blood cells in the form of iron-containing protein - hemoglobin, as hematogen prepared from dry cattle blood (blood is processed with the help of modern equipment in order to avoid infections, at the same time retains all its beneficial properties) with condensed milk, honey, ascorbic acid and other substances that improve its taste. Exterior Tiles hematogen resemble small chocolates, with a peculiar but very pleasant taste.

Hematogen helps restore metabolic processes, stimulates blood formation. Furthermore, it hematogen a source of essential amino acids, carbohydrates, mineral fats, vitamins and minerals. The most valuable is the fact that all these substances are hematogenous in a state close to the composition of our blood.

Hematogen particularly rich in vitamin A Vitamin A: An important element of the health and beauty Therefore welcome it helps to restore vision, skin functions, proper hair growth and the growth of the organism as a whole, especially in adolescence.

Hematogen remarkably established itself in the Great Patriotic War, when it is based on the wounded were preparing various dishes to facilitate the rapid restoration of health. In those years, even scrambled eggs prepared for the wounded on the basis of liquid hematogen.

Indications

Hematogen ingested orally in accordance with the instruction (as in various formulations contained various amounts of iron) under the following conditions:

• malnutrition;
• repetitive bleeding and low hemoglobin Hemoglobin: worse - low or high?   blood;
• after heavy infectious diseases (such as the flu);
• chronic diseases, especially gastric ulcer and 12 duodenal ulcer, which are likely to frequent, not always noticed by bleeding;
• as part of an integrated treatment of the different types of impairment;
• in dry inelastic skin;
• while stunting.

Despite its apparent simplicity, the treatment of hematogenous better align with the doctor not to expect the impossible from him: hematogen will not in any anemia, as is his views are not associated with iron deficiency.

Do not take hematogen in diabetes Diabetes - threatening and incurable disease   and obesity, as it contains digestible carbohydrates. Of course, do not take it and in case of hypersensitivity to the drug.

Very rarely but, nevertheless, there are side effects from the reception hematogen as nausea and diarrhea. This is due also to the presence of carbohydrate plates that contribute to the process of fermentation in the gut.

Hematogen - beautiful, undeservedly forgotten medication. He almost never cause side effects, and has a mild positive effect on the body. Hematogen can be applied not only medical but also as a prophylactic measure, for both children and adults.
