Myths about nutrition, which should not believe

E-components - a synonym for chemistry, foods with GMOs are hazardous to health - doctor-gastroenterologist Alexei Paramonov told about popular myths about foods and nutrition.

Products with GMOs are harmful

What say, genetically modified foods contain other people's genes, which means that they are dangerous to health and the human body and can cause the development of various diseases.

In fact: foods contain GMOs foreign organisms for this type of gene, entered with a practical purpose. For example, to not eat potato or potato beetle to increase the starch content of corn. Regardless of the source of the embedded gene GMO products entering the gastrointestinal tract, inevitably fall into amino acids, glycerin, fatty acids, monosaccharides and nucleotides that do not differ from the compounds obtained by the digestion of classical organisms wild or derived from selection.

On the other hand, genetically modified organisms may represent an environmental threat - they are more adapted to the environment, are not afraid of pests and diseases. But this aspect is beyond the scope of a medical assessment of GMOs, besides firms producing GMOs, we developed successful mechanisms to control these substances.

E-components in the product is also harmful to health

What they say: if there is in the product name with E, such goods is better to put back on the shelf. Nothing useful in it for sure is not - a solid chemistry and harm.

In fact: E - is adopted by the European system of abbreviated names of nutrients. Under E numbered hidden not only edible colorants or preservatives, but the familiar kitchen substances such as vinegar, citric acid and vitamin C. Even

Yoghurt - the most useful food

What they say: Yogurt contains beneficial bacteria, beneficial effect on the functioning of the organism and its microflora, as well as establishing the digestive system. And yet they are tasty and not very high in calories even though they contain sugar.

In fact: natural yogurt with no sugar - a good choice: they are balanced in content of proteins, fats and carbohydrates, nutritious, do not contribute to weight gain, contain lactic acid bacteria, which can be protected, for example, from an intestinal infection and antibiotic-associated diarrhea . Sweet Yogurt should be regarded as a dairy dessert. sugar content of up to 10% - this is unacceptable for patients with diabetes and obesity. But the thin, athletic people and children sweet yogurt will not bring harm.

Products with sodium glutamate harmful to health

What they say: monosodium glutamate - a chemically synthesized substance, which means that it is harmful to health. It is better to avoid it and choose natural products.

In fact: it's like saying that the dangerous protein products. Glutamate - an essential amino acid, a component of any protein. In one steak it contains much more than in any ersatz product such as instant noodles, where it is added to improve the taste. It glutamate gives the meat flavor. For the preparation of many dishes of Oriental cuisine uses sauces based on natural glutamate. is no different from the synthetic glutamate natural and completely harmless.

Bifidobacteria useful for the organism.

What say you need to eat as much dairy products because it contains a lot of bifidobacteria, and they are useful for the body and health. So write on the packaging of yoghurt.

In fact: likely true useful bifidobacteria. In modern clinical studies reviewed by a very small amount of bacteria, mainly lactobacilli. Relatively few of them have proved the following: they prevent and treat infectious diarrhea, as well as act as a prevention of antibiotic-associated diarrhea and colitis clostridial. But all the bacteria in our food that data can be shared in part with some reservations, and it is only speculation.

All products that contain chemicals that are harmful to health, and all the natural beneficial

What they say: if you want to be healthy and to live a hundred years, it is necessary to abandon the non-natural foods, eat only vegetables, fruits and herbs. After all, there is no chemistry.

In fact: the whole world around us is made up of chemicals. Products consisting not one of them does not exist. You can oppose each other synthetic substances, produced at the plant and natural, derived from organic and inorganic nature. But two centuries known law of definite proportions of substances - whether vitamin C is synthesized in the plant or in the lemon tree, all the chemical properties of these two molecules with different ancestry are identical.

Milk is bad for the body and bones.

What they say is, milk is bad for bones and does not contribute to their strengthening. And indeed, it contains lactose, which is also a negative impact on human health.

In fact: the milk - a source of protein and calcium. This is something that just need the bones. On the other hand, a quarter of the world's population - adults - lose the ability to digest milk sugar, and it all goes to the intestinal bacteria, which makes it a good laxative. But these men, knowing the feature, do not drink milk.

Pink sausages said the addition of harmful substances, and gray - naturalness

What they say: pink - unnatural color to the food. He suggests that the manufacturer adds a lot of preservatives, dyes and other harmful substances, such can not be eaten. But the gray color - it's good, it's useful.

In fact, if cook meat, particularly beef, it will be gray. Contrary to the malicious insinuations that the sausage is made from toilet paper declare: still the main ingredient in its production - meat. To beef does not become gray in sausage, sodium nitrite is added in amounts that give it a pink color, but does not pose a health risk.

However, recent studies have shown that regular consumption of processed meat products, especially red and smoked, increases the risk of developing colorectal cancer. But this is to link with sodium nitrite, we can not. Therefore, any sausage, pink or gray, should not be the basis of power. It is best to choose a natural white meat: chicken, turkey, rabbit, fish. And if there is a sausage, it is not every day, and together with dietary fiber in the form of vegetable side dishes.
