Vinegar was invented by Du Kang, the son of an ancient wine-making master. After he learned wine-making technology, he thought it was a pity to throw away the distiller's grains, which inadvertently led to "vinegar". Later, vinegar became a common cooking seasoning. Drinking vinegar often can eliminate fatigue and soften blood vessels. Benefits of drinking vinegar: 1. Digestible fat and sugar vinegar contain substances such as amino acids and organic acids. The amino acids contained in vinegar can promote excessive fat in the body to be converted into physical consumption, and can also digest sugar absorbed by the body. 2. It can reduce the intake of salt. Eating too salty is not only a heavy burden on the body, but the more salty you eat, the more water you drink. When you drink too much water, it is difficult to accumulate in the body without gaining weight. 3. Diuretic laxative vinegar can promote metabolism and increase gastrointestinal peristalsis. Vinegar has diuretic function, and drinking a small amount of vinegar can effectively improve constipation. Although vinegar is good, you should pay attention to four points when drinking vinegar: 1. At most, 1-2 cups of diluted vinegar a day is not harmful, but drinking a lot of vinegar will cause too much irritation to the gastrointestinal tract. 2. Not drinking vinegar on an empty stomach stimulates the secretion of too much gastric acid and damages the stomach wall. Drinking vinegar between meals, or one hour after meals, is less irritating to the gastrointestinal tract and helps digestion. 3. Patients with gastric ulcer and hyperacidity should not eat vinegar because vinegar will not only corrode gastrointestinal mucosa and aggravate the development of ulcer disease, but also vinegar itself is rich in organic acids, which can make digestive organs secrete a lot of digestive juice, thus increasing the digestion of gastric acid, so as to avoid gastric acid increase and ulcer aggravation. 4. People who are taking some western medicines should not be jealous. Sulfanilamide drugs are easy to form crystals in the kidney and damage the renal tubules in an acidic environment, so taking such drugs should not be jealous.
