Experts have debunked several popular myths about human health.
To maintain and improve health, need to make an effort. But some follow the advice of so fanatically that, in the end, not enhance health, but harmful to him. We offer you to find out the most common myths about health.
A day you need to consume at least 8 glasses of water, this will help to normalize the water-salt balance and excrete toxins. Actually, of course, the human body needs a certain amount of fluid, and it really is about 2 liters, but some (including unqualified dietitians and doctors) do not take into account the fact that the fluid is contained in many beverages and foods. For example, most fruits and vegetables more is precisely out of the water. So it is not necessary to drink water by force. But to neglect the drink is not worth it. Drink as much as your body needs, that is, listening to their feelings. Sure to replenish the fluid loss in hot weather and at high physical loads. And remember that overuse of water can lead to problems in the kidneys.
The consumption of sweets can lead to hyperactivity. Yes, sweet is the so – called fast carbohydrates that are consumed in energy production. But actually there is no scientific evidence that eating sweets leads to a surge of activity (even in children). In addition, it is proven that sugar, once in the body, stimulates the production of the hormone serotonin which has a relaxing and calming effect on the nervous system. So “sweet hyperactivity” is nothing more than a myth.
Reading in a poorly lit room leads to deterioration of vision. Have been telling all mothers to their children, as well as opticians to their patients. Yes, reading in the twilight is not very comfortable, but as it turned out, the visual acuity it has no effect. Otherwise, almost all of our ancestors would wear glasses and could not see, after all, before any of the fluorescent lights was not still read by the light of kerosene lamps, which, of course, does not provide sufficient lighting. But in those days (by the way, then read and loved), people suffering from myopia, was not more than now. As for the present, today there are many other adverse factors that may have an adverse effect on vision (e.g., prolonged work at the computer, smog, dusty air).
Chewing gum is decomposed in the body for several years and can lead to intestinal obstruction. These all were scared of parents. Actually accidentally swallowed one piece of gum can lead to serious consequences. What will happen after penetration of chewing gum into the body depends on its composition. But the scenario only two. At best chewing gum will be digested in the stomach (it will process the gastric juice). In the worst case, the gum will pass through the stomach through the intestines and come out in the form in which received, naturally. Yes, the cases of intestinal obstruction as a result of ingestion of chewing gum are known, but in the intestine was several.
Eating chocolate may trigger acne. Actually beloved the sweetness in no way affects the skin condition. The causes of acne are many, among them, such as hormonal disturbances, pollution of the epidermis, clogged pores, overactive sebaceous glands. But the food on the condition of the skin is not affected, contrary to popular belief. And a few pieces of chocolate (preferably bitter) not only harm but also be useful, because chocolate improves mood.
Eating before bed will lead to weight gain. Yes, actually there on the night and especially overeating is not helpful. This is due primarily to sleep disturbance. And this is because the digestive tract is a well-deserved night’s rest will be forced to work, digesting the food you consumed. But getting fat is only the evening meal is almost impossible. No, of course, with regular overeating in the evenings you will gain weight. But your body weight will increase and if you will overeat to 6 PM. All the calories you consumed for the day and had not managed to consume (even the ones you got at lunch or brunch), leave “in reserve”, that is, turn into extra pounds.
Caries is a consequence of eating sweets. Previously it was thought that sugar contained in sweets, remains on the surface of the teeth and in the mouth and creates favorable conditions for bacteria. But actually it is not so. Recent studies have shown that dental caries does not lead the carbohydrates found in sweets and any food residues. It was found that the fast carbs contained in the sugar, washed the saliva from the oral cavity rather quickly. But complex carbohydrates that are included with baked goods, fruits, cereals, and meat products, dissolve a very long time. And the splitting of such products starts right in the oral cavity, and this process involves saliva and the contained microorganisms. And that the activity of these microorganisms provoke the development of caries.
Eating eggs can lead to higher level of harmful cholesterol in the blood and the development of atherosclerosis. Yes, in the 60-70-ies of the last century, scientists have established a link between increased levels of cholesterol in the blood and blamed eggs (why they did this is not clear). But a recent study showed that the increased risk of cardiovascular diseases associated with high saturated fat content in food. But such products were not necessarily eggs. But actually in one chicken egg contains only 1.5 grams of saturated fat, while one Cup of milk 2% fat more than 3 grams. So don’t blame the eggs. Should take a responsible approach to menu planning nutrition and to evaluate all the products. But to abuse the eggs is not necessary, they are considered a rather heavy food.
