Vinegar can be roughly divided into three types, namely brewing vinegar, synthetic vinegar and white vinegar. The largest number in China is fermented vinegar. Scientific analysis shows that fermented vinegar contains not only 5%-20% acetic acid, but also organic acids such as amino acids, lactic acid, succinic acid, oxalic acid and nicotinic acid, minerals such as protein, fat, calcium, phosphorus and iron, vitamin BI, vitamin B2, sugar and aromatic substance ethyl acetate. The content of organic acids and amino acids in rice vinegar made from rice is the highest. According to modern medicine, vinegar has the following functions in treating diseases and preserving health: 1, eliminating fatigue; 2. Adjust the acid-base balance of blood and maintain the relative stability of human internal environment; 3, help digestion, which is conducive to the absorption of nutrients in food; 4, anti-aging, inhibiting and reducing the formation of peroxide in the process of human aging; 5. Strong bactericidal ability, which can kill staphylococcus, Escherichia coli, dried bacteria, halophilic bacteria, etc. In the intestine; 6. Enhance liver function and promote metabolism; 7. Dilating blood vessels is beneficial to lowering blood pressure and preventing cardiovascular diseases; 8, enhance renal function, have diuretic effect, and can reduce urine sugar content; 9, can make the body's excess fat into physical exertion, and promote the metabolism of sugar and protein, which can prevent obesity; 10, vinegar also contains anticancer substances. ● Vinegar can't adjust the pH of blood. Many people drink vinegar every day for health, because they think that although vinegar tastes acidic, it is an alkaline food after entering the human body, so it can adjust the pH value of blood and make people less likely to get sick. Under normal circumstances, human blood is weakly alkaline (about PH7.4). Nutritionists point out that a few foreign studies have found that people with alkaline blood are healthier, while people with acidic blood are at higher risk of illness. There is also a folk saying that eating meat will make the body sour, eating vegetables, fruits, drinking vinegar and so on. You can adjust your physique and return to an alkaline state. But can eating certain foods really change the pH value of blood? Many western nutritionists point out that there is no scientific basis to prove this statement, and even Chinese medicine does not agree with the statement that this diet changes the pH value of the body. Western nutrition believes that the human body has its own mechanism to maintain the balance of blood pH, which involves complex enzyme action, and I am afraid that it can't be changed just by eating a certain food. Low vinegar can't lose weight. Drinking vinegar to lose weight was all the rage. It was popular in Japan and Taiwan Province Province to soak soybeans in vinegar and pickle them into vinegar beans, claiming that eating 10 ~ 20 capsules every morning and evening can achieve the effect of losing weight. It is said that vinegar can improve human metabolism and prevent fat accumulation, but nutrition experts shake their heads and say that there is no exact research to support this claim. Some nutritionists theorize that if you really want to lose weight by drinking vinegar, it may be that your mouth is full of vinegar and you can't eat anything else, or that you have replaced your usual high-calorie snacks with vinegar beans. In contrast, your calorie intake will be reduced. However, this method of losing weight can't last long. In the long run, it will lead to nutritional deficiency and imbalance, which will consume a lot of health. Weng Huiling reminded that on the contrary, some vinegar products will add a lot of sugar to enhance the taste if they are vinegar drinks, and the calories are not low. When buying, you can pay attention to whether sugar is listed in the ingredient list, or whether it contains the calories and carbohydrate content marked by nutrition. Therefore, it is doubtful whether drinking vinegar can lose weight. ● Vinegar can stimulate appetite. The sultry summer makes people lose their appetite. Eating some hot and sour dishes can stimulate their appetite. Seasoning with vinegar is one of the simple methods, for example, using vinegar and olive oil to make oil-vinegar salad dressing with lower calorie than Thousand Island Sauce, using vinegar, minced garlic and pepper to make cold seafood, or using vinegar to pickle cucumber, lotus root and bitter gourd as appetizers before meals in summer. Nutritionists suggest that letting chronic patients with poor appetite and elderly people with degraded taste eat vinegar in moderation can adjust their appetite and improve their diet. ● Vinegar can stimulate gastric acid secretion and help digestion. A moderate amount of jealousy is helpful to some people with less gastric acid secretion. But people with normal digestive tract function don't have to drink vinegar to improve digestion. Moreover, people with normal gastric acid secretion will not necessarily increase the amount of gastric acid secretion if they drink vinegar again. ● Vinegar can prevent hypertension. "Less salt and more vinegar" is a traditional healthy diet for China people. Modern people who often eat out and eat a lot of processed food have already exceeded the recommended amount of 6 grams per day. If we can make good use of vinegar to increase the flavor of dishes and reduce the use of salt, we can really reduce the risk of diseases such as hypertension, arteriosclerosis, coronary heart disease and stroke. In addition, fruit vinegar contains mineral potassium, which can help the body discharge excess sodium and achieve the purpose of preventing hypertension. Of course, eating fresh vegetables and fruits can also achieve the same effect. Chinese medicine also uses vinegar to pickle peanuts as a dietary therapy to regulate blood pressure-soak peanuts in vinegar for more than 7 days, and then eat 10- 15 peanuts every day for more than a week. ● Vinegar can help intake calcium. When cooking ribs soup, you can add a small amount of vinegar, which will help release calcium from bones and make it easier for us to absorb calcium. After reading all the above statements, it is not difficult to find that many popular methods of drinking vinegar are mostly personal opinions and feelings, and scientific evidence is insufficient. In this case, is it necessary for us to be jealous and drink vinegar every day? According to experts, a moderate amount of jealousy is harmless to health. However, the health care function of vinegar can be achieved as long as the diet is balanced, and it is not necessary to drink vinegar. Therefore, there is no need to expect too much from vinegar, let alone think that it can cure diseases. Whether to drink vinegar every day is purely a personal diet and health preference. People who are not used to drinking vinegar occasionally mix a cup of vinegar for a change as a way to increase the fun of life. It is necessary to remind you of the timing and weight of jealousy. Improper diet will do harm to your health. ● Don't drink vinegar on an empty stomach. No matter how strong your stomach is, it is not suitable for drinking vinegar on an empty stomach, so as not to stimulate the secretion of too much gastric acid and damage the stomach wall. Drinking vinegar between meals, or one hour after meals, is less irritating to the gastrointestinal tract and helps digestion. ● At most 1-2 cups of diluted vinegar every day, a small amount of jealousy is harmless, but anyone who drinks vinegar in large quantities like a jealous jar is too irritating to the gastrointestinal tract. Moreover, fruit vinegar or other vinegar drinks on the market often add a lot of sugar. If vinegar is used instead of boiled water, tea and other drinks, it will increase a lot of calories. If you drink it for a long time, the probability of obesity will increase greatly, which is not conducive to weight control. The health function of vinegar vinegar is also bitter wine, which is not only a common cooking seasoning, but also a common Chinese medicine. In recent years, people pay more and more attention to the health care function of vinegar. There are ten commandments for longevity in Japan, among which "less salt and more vinegar" is listed as the second. Some people sum up that vinegar has four health-care functions: first, it lowers blood pressure and prevents arteriosclerosis; The second is sterilization; The third is to prevent and eliminate fatigue; The fourth is to moisturize the skin. Rice vinegar contains more than 20 kinds of amino acids and 16 kinds of organic acids, which can promote sugar metabolism, eliminate fatigue, reduce cholesterol and prevent arteriosclerosis. The experiment shows that general bacteria die after soaking in vinegar for 10 minutes, while tableware can kill bacteria that cause food poisoning after soaking in vinegar for 130 minutes. The residual pesticides and radioactive dust on vegetables and fruits can be washed with vinegar aqueous solution. The results show that vinegar can protect the vitamins contained in vegetables from alkaline media and oxidative damage. Among the growing elderly population in China, there are more and more osteoporosis patients, which has aroused great concern of scientists. Calcium supplementation has become a top priority. The most important health care function of vinegar lies in promoting the absorption of calcium by human body. As we all know, 99% of calcium in human body exists in the form of calcium salt, and only 1% exists in soft tissue, extracellular fluid and blood in the form of bound or free ions. The function of vinegar is to convert insoluble calcium in food into soluble calcium, thus increasing the concentration of soluble calcium in digestive tract and accelerating the absorption of calcium. Some people like to eat pig bone soup to supplement calcium. The determination of bone soup by the clinical nutritionist of Guangdong Sun Yat-sen University of Medical Sciences shows that the calcium content of bone soup cooked in the pressure cooker for half an hour to two hours is far less than that of 100 grams of milk16. However, if some vinegar is added to the bone soup, the calcium content in the soup can be increased by 10 times. Being jealous often has a cosmetic effect, which is an important discovery in recent years. Now, vinegar has been used for anti-wrinkle, beauty, hair care, weight loss and so on. Regular consumption of vinegar can enhance the function of human skin cells, delay skin aging and gradually eliminate skin dark spots. The beauty secret of Cleopatra, a peerless beauty in Egypt, is to drink a small cup of vinegar (pearl vinegar) dissolved in pearls every day. Recently, American experts suggested that amino acids contained in vinegar can not only consume body fat, but also promote the smooth metabolism of sugar and protein, which can play a good role in losing weight. Of course, advocating "less salt and more vinegar" does not mean drinking vinegar like water all day. Vinegar can be drunk directly, limited to a small cup a day. Generally speaking, vinegar has ten health-care functions: 1, eliminating fatigue: rich organic acids can promote carbohydrate metabolism, decompose fatigue substances in the body, and eliminate people's sense of burnout. 2. Balance blood pH: vinegar is an acidic food. After eating too much fish, meat, polished rice, bread and other foods, drinking vinegar can help digestion and maintain the acid-base balance of body fluids. 3, help digestion: vinegar contains volatile substances and amino acids. Can stimulate the nerve center of the brain, make the digestive organs secrete a lot of digestive juice, and enhance digestive function. 4, prevent aging: vinegar can inhibit and reduce the formation of lipid peroxide in the process of human aging, reduce the generation of senile plaques. 5, dilate blood vessels: vinegar can lower blood pressure, prevent cardiovascular diseases, reduce urine sugar content and prevent diabetes. 6. Enhance renal function: vinegar can induce diuresis, prevent constipation, and prevent and treat kidney calculi's disease, gallstones, bladder stones and other diseases. 7. Enhance liver function: vinegar is rich in nutrients such as acetic acid, amino acids and lactic acid, which can improve liver function. 8, improve the bactericidal power of the stomach: vinegar has a strong bactericidal effect, can kill staphylococcus, Escherichia coli and so on. 9. Beauty and skin care: Acetic acid, lactic acid and amino acids contained in vinegar can promote blood circulation and make people's skin smooth. 10, preventing obesity: amino acids in vinegar can consume excessive fat in the body and have a good weight loss effect.
