How does hunger affect us? Detailed answer
Directory / Big encyclopedia. Questions for quiz and self-education Did you know? How does hunger affect us? The feeling of hunger is a brain signal to our body. The signal is given when there is a lack of nutrients in the blood. Let's see how it goes. In our body, a constant metabolic balance must be maintained, that is, metabolism must be carried out. This means that there must be a certain balance and control over our food intake and processing. There are three things that regulate our body weight: thirst, hunger and appetite. There is a hunger center in the brain. Its effects inhibit the work of the stomach and intestines. The hunger center stops the activity of the stomach and intestines if there are enough nutrients in the blood. But if they are not enough, the stomach and intestines become active. That's why you can hear your stomach growl when you're hungry. But hunger by itself can do nothing with an empty stomach. For example, if a person has an empty stomach, but he is excited, then he will not feel hungry. In this case, the human body consumes protein and nutrients from its internal reserves. When you feel hungry, it means that the body needs various nutrients. Indeed, a hungry person is ready to eat any food. Your appetite makes sure that your food choices match your body's needs as closely as possible. For example, at dinner, a person might eat a whole bowl of soup, followed by meat and vegetables. In addition, he can eat dessert, cake, drink coffee. But it will be very difficult for him to eat exactly the same amount of food if it consists of one potato! Metabolism determines how long a living being can go without food. Warm-blooded animals have a more active metabolism, so their supply of nutrients is consumed faster. Author: Likum A.
What color was Robin Hood's tights? Red. The earliest stories about Robin Rude date back to the XNUMXth century. In the longest and most important of them, "A Gest of Robyn Hode", Robin and his "merry gang" are dressed in "scarlet robes" of striped fabric. In other ballads, Robin appears alternately in red and scarlet, while his fellows are invariably dressed in green. Thus, Robin's status as a commander is emphasized: in medieval England, "scarlet" cloth was considered the most expensive, since kermes, obtained from dried female kermes worms (Kermes ilicis), was used to dye it. This also explains the origin of Robin's name - an association with a robin bird (robin redbreast) - and one of his closest associates, Will Scarlet (Scarlet (English) - scarlet, bright red.). Only in later versions does the color of the Sherwood legend's outfits become bright green - although, if you think about it carefully, "Lincoln Green" may not be so green at all. In medieval England, Lincoln was the capital of the dye industry. The color "Lincoln Green" was indeed bright green (blue paint made from mignonette was dyed yellow), but "Lincoln Grain" was just the same scarlet - the paint was prepared from kermes, at that time known by the word "graine". The early Robin Hood ballads are simply obsessed with clothing. In addition to the fact that the "noble robber" himself is nicknamed in honor of his headdress (The word hood is translated from English as "hood".), in the "Small Song" almost every stanza mentions robes, dresses, capes, trousers, shirts and fabrics in six different colors, and in one of the songs, Robin even pretends to be a manufactory merchant and sells 123 feet of green cloth to the king. At least one historian puts forward the following version: the true essence of the stories about Robin Hood is not at all in the traditional struggle "forest against city" or "poor against rich." In his opinion, the main thing in these ballads is the victory of the merchant-adventurer over the decaying, corrupt nobility. Like, Robin Rude, dressed in expensive red cloth, actually defended not the poor, but only the emerging middle class.
