Onion benefitsHistoryOnion is an ancienta culture whose exact origin has not yet been established. It is generally accepted that the homeland of onions is Transcaucasia or Central Asia. It is also known that onions were grown in Ancient Greece, Egypt, and India. It has long been believed that onions are not only a medicinal plant, but also a storehouse of magical properties. Roman legionnaires were required to eat them, since, according to popular belief, food with a lot of onions gives courage, energy, and strength. In the 10th-12th centuries, commoners in France, Spain, and Portugal ate them every day. And in Rus', they appeared in the 12th-13th centuries.Nutrients Currently known around400 types of onions (bulb, shallot, leek, batun, multi-tiered, etc.). In our country, there are 230 species. Bulb onions received particularly widespread. In culture, it was known over 4 thousand years BC, it was not found in its wild form. The healing power of onions is due to the unique combination of a large number of useful substances. Bulbs are rich in carbohydrates and nitrogenous substances, they contain fiber, pectin, vitamins C, B1, B2, PP, essential oils, volatile production, potassium, calcium, etc. Compared with the bulb contains 3 times less vitamin C, and the green cousin is unusually rich in carotene, potassium, and phosphorus. And yet you should not rely on onions as a vitamin preparation. It turns out that in order to satisfy the need for vitamin C, you will have to eat at least 300 g of fresh green feathers every day. Onions for this will require about 1 kg. As garlic, by the way, is mainly due to the presence of natural antimicrobial substances - phytoncides. And, nevertheless, onion, like garlic, is not for everyone. These aromatic vegetables contain a large amount of essential oils that are capable of strongly irritating the mucous membranes and causing allergic-type reactions. In the diet of a healthy person, onions can be used with almost no restrictions.DiscoveryThey say about onions:"who undresses it, sheds tears." Although it is possible that this riddle will soon be left without an answer. After all, scientists from New Zealand recently announced a real breakthrough in biology. Experimenters have developed the so-called "onion without tears" using the "gene shutdown" technology. The story began 6 years ago, when Japanese specialists determined what makes a person cry. It turned out that a certain gene produces an enzyme that irritates the mucous membrane. After that, New Zealand breeders took up the matter. They placed a special DNA recoder in the onion. It, in turn, stopped the path that led to the formation of tear enzymes. Now, according to scientists, they will be able to improve not only the taste, but also the health benefits of onions. We should not expect such a miracle vegetable to appear on our table earlier than in 10 years. This is the time frame in which the researchers promise to complete all experiments.Good adviceGoing to stock up on this naturalmedicine on the market or in the store, pay attention, friends, so that the onion was dry, without rotting. If the surface of the bulb is wet, such a bow does not lie for a long time. In no case do not put onions in the refrigerator, especially in a plastic bag, in such conditions it will quickly suffocate and begin to rot. I wish a rich onion harvest to those who grow it with their own hands, pleasant purchases to all who stock up onions in the consumer market, and to absolutely everyone - good health and no tears!
