Myths about food, which have long ceased to believe
The theme of food has always been and will be extremely relevant and endless myths are constantly forming around it. Some of them had to be refuted scientifically.
Our ancestors did not know much about food and how various foods affect our bodies. The digital age has opened up new opportunities for man to study himself and his body. However, there is a downside: a huge amount of information roams from mouth to mouth, which provokes the emergence of numerous myths about food.
Fortunately, most of these contradictions have been successfully debunked recently, giving way to reliable information. Scientific discoveries, research, the emerging culture of rational and conscious consumption allow you to learn more relevant information about food and its nutritional properties.
We made a list of the most common myths about food, which you need to stop believing, because they were denied by science itself. Do not let yourself be fooled!
Myth (other Greek word, word, legend, legend) is a narrative that conveys people's ideas about the world, the place of man in it, the origin of all things, about gods and heroes.
Food is something that is eaten or eaten - any substance suitable for eating and drinking to living organisms to replenish energy reserves and the necessary ingredients for a normal course of chemical metabolism reactions: proteins, fats, carbohydrates, vitamins, minerals and trace elements. Nutrients enter the living organism, where they are absorbed by the cells in order to generate and store energy, maintain life, and provide growth processes and maturation. Usually food is divided by origin into vegetable and animal. With regard to the nutrition of domesticated animals, the concept of food is common and used. The field of human activity associated with cooking is called cooking (kitchen craft).
The main purpose of food - to be a source of energy, renewable materials (for example, water) and "building material" for the body, however, the factor of obtaining pleasure (satisfying hunger) from food is also important in human nutrition.
Do not use wood chopping boards from wood
At some point, all sharply declared a taboo on cutting boards made of wood. Real aesthetes and lovers of natural materials poskorushalis, but had to accept, because the argument was weighty. There was information that when cutting meat and poultry on the board are microscopic scratches and depressions, in which bacteria are concentrated.
Studies conducted by scientists from the University of California, proved that this is not so. Regardless of the material of the board, it is important to carefully care for it and disinfect its work surface. That's the whole secret!
Salty water boils faster
On numerous sites, the authors share culinary lifhakas and advice, which will teach you how to prepare masterly in minutes. It was very popular that the salt water boils much faster than usual.
Chemistry proves the opposite: it does not matter how much salt is in the water, because it does not affect the boiling point of water. This makes it absolutely new to look at the chemistry lessons at school and be upset that the academic progress on this subject left much to be desired.
Low-fat products are more useful
Fats terrify modern people. They are accused of all the troubles, so many try to exclude them as much as possible from their diet. This is not so, but smart marketers quickly picked up this trend and launched a whole line of low-fat products: curds, dairy products, yogurts, kefir and further down the list.
In low-fat products, unfortunately, there are few "good" fats and many "harmful" fats. Prefer milk products with a normal percentage of fat, nuts, seeds, fish.
The best source of calcium - dairy products
Since childhood, a stereotype exists in our minds that milk is the best source of calcium, which is very useful for bone growth and health. In fact, this element is quite abundant and in dark leafy greens - cabbage and spinach.
For bones, magnesium and vitamin K, which are not found in milk, are also useful. Where to find them? Again, leafy greens, almonds, cashews, oatmeal, potatoes. To strengthen the bones do not just limit the milk, and include in the diet and other useful products.
In a day you need to drink at least 8 glasses of liquid
Unqualified nutritionists at one time advised to lose weight at least 8 glasses of water a day. Such sacrifices are useless, because we are all different. For someone, such a quantity of liquid is too much. Focus on your feelings and feelings.
Take the rule of drinking a glass of water half an hour before a meal and drink during training. This is the minimum from which you can begin. Later, your body itself will require the required amount of fluid.
Foods high in sodium are too salty to taste
This is surprising, but not all foods with a high sodium content differ in the same high salt content. It is important to know if you follow the health, figure and are afraid of the development of hypertension and diabetes.
Salts and sodium are equally abundant in baking, half-finished products, fast food and sauces. As for the other products, you should carefully study their composition to find out valuable information about the salt content.
Eggs raise cholesterol levels
Egg yolks do not enjoy the same popularity as proteins. They say that they raise the level of harmful cholesterol in the blood, which provokes the appearance of diseases of the heart and blood vessels. Is it true?
Studies have found that the level of harmful cholesterol in the blood is affected by saturated fats and trans fats. In the eggs of these substances is not so much. So, in one average egg contains about 1.5 grams of fat, and trans fats are not at all. The blood gets only a small part of the cholesterol, which in no way can affect the health of the cardiovascular system with moderate use.
Aluminum materials have a detrimental effect on health
In the last century in America, a study was conducted in which a high level of aluminum in the brain was found in patients with Alzheimer's disease. This information caused a wide resonance in the society. As a result, aluminum utensils and foil became undesirable attributes in the kitchen.
After many years, different scientists independently conducted a series of studies, but they did not confirm these guesses. It was proved that all aluminum is processed by the kidneys and excreted in the urine, so it can not provoke the occurrence of Alzheimer's disease in any way.
The crust "seals" all the juices in the meat
You will be surprised, but this culinary lifhak is based on a study that took place in the XIX century. German chemist Justus von Liebig conducted an experiment with the preparation of meat.
One piece he cooked in water, and another cooked on a hot surface simulating a modern oven. The fried meat turned out to be more juicy, as a result of which, Liebig decided that the crust had made him that way, "sealing" all the juices inside. Although in fact in the first case, all the juices simply boiled out of meat.
In the 21st century, Harold McGee, author of the book "On Food and Cooking," repeated this experience. He tried to bake two pieces of meat: with a crust and without. The result surprised him: the meat without crust was more juicy and tender.
You can not eat after six
This is the most insidious and dangerous myth that can only be imagined. With the modern rhythm of life, many of us go to bed after midnight. If people do not eat after six, they can not fall asleep from the raging hunger and rumbling in the stomach.
We share the updated data: the last meal should be 3-4 hours before bedtime and should be easy. It takes exactly as long as the human stomach can calmly process the food and can rest.
