Serbian tennis player Novak Djokovic after he felt health problems, went on a diet, eliminating all flour. And it really helped. After that, he regained form and continued to win sports victories. The refusal of sweet and starchy foods is of benefit only if necessary for medical reasons, sure nutritionists. Often this diet used for weight loss, but the result does not meet expectations.Nutritionist and trainer Marie Spano explains, excluding flour from your diet, people begin to lose weight almost to the eyes. But not everyone understands that takes no fat and liquid. The fact that the carbohydrates, which we get mainly from flour are contained in organism in the form of glycogen — each gram of carbs holds around myself 3-4 grams of water.According to Marie Spano, refusing to flour, the person begins to experience insomnia, nausea, dizziness, and most importantly, it slows down brain activity. To compensate for the lack of carbohydrates, which are the main supplier of energy, the body begins to use ketone — hydrocarbon particles. Their use leads to unpleasant breath, weakness and chronic fatigue. Gradually the body gets used to the “new fuel”, fatigue symptoms disappear, but to be a perfect substitute energy supplier ketones can’t.American Heart Association (American heart Association) has published data showing that the rejection of products from cereals by 20-30 days affects the level of the neurotransmitter serotonin in the brain. So, the less carbs, the worse mental health. In addition, cereals can help to reduce the risk of cardiovascular disease, stroke, obesity and even diabetes mellitus of the second type. The Association’s specialists explain that carbohydrates are the main source of energy for all organs, growth and cell division.Received less carbohydrates, the body is in an extreme situation: it first consumes muscle glycogen, and then fat. During this period, his kidneys have a huge amount of load, from which the whole body suffers.The candidate of medical Sciences Marina Kopytko said that in theory starchy foods you can give up entirely, but the body should get all those nutrients contained in starchy foods, among other products. In practice, I’m sure the doctor, this is not recommended. So, wheat and rye contain from 10 to 13 per cent protein, 6 to 70 percent of carbohydrates, from 2.5 to 4 percent fat. Only 200 grams of bread a day cover the human need of 25-30 percent of the daily value of protein, 30-40 carbohydrates. In addition, the bread can partially satisfy the body’s need for calcium, phosphorus, potassium, magnesium and iron. Plus, of course, proteins. Not by chance were born in Russia, the expression “bread around the head”.But German scientists have found that, having only bread, man is deprived of antioxidants, which prevent the development of colon cancer. This was announced by Dr. Thomas Hofmann, head of project studying the effects of cereals on the human body. By the way, German experts are assured that in the crust of bread nutrients much more than in the crumb. Moreover, according to Dr. Hoffmann, bakery products with dark-brown crust, in contrast to the poorly baked, with a light crust, contain beneficial antioxidants eight times more. And there are these nutrients only in the baked products is the flour they are not.If to speak about the benefits of a diet without starchy foods, nutritionists different countries in one voice say: to refuse should only be from products from refined flour: bread and rolls made from white flour, biscuits and other things. So, the team that Thomas Hoffmann explain: after eating pastry from whole wheat flour, even in small amounts, in addition, that person receives a large amount of nutrients, it is a long time not feeling hungry. And after the products made from refined flour already after a short time there is a desire to eat something.
