Vinegar can be roughly divided into three kinds, namely brewing vinegar, synthetic vinegar, white vinegar. The most popular vinegar in our country is brewing vinegar. Scientific analysis shows that brewing vinegar contains 5%-20% acetic acid, but also contains amino acids, lactic acid, succinic acid, oxalic acid, nicotinic acid and other organic acids, proteins, fats, calcium, phosphorus, iron and other minerals, vitamins BI, B2, sugar, and aromatic substances, acetic acid and ethyl vinegar. The content of organic acid and amino acid is the highest in rice vinegar made from rice as raw material. According to modern medicine, vinegar has the following effects on the treatment of disease and health care: 1, eliminate fatigue; 2, regulate the acid-base balance of blood and maintain the relative stability of the environment in the human body; 3, help digestion and facilitate the absorption of nutrients in the food; 4, anti-aging, inhibit and reduce the formation of peroxides in the process of aging of the human body; 5, it has a strong bactericidal ability and can kill staphylococcus bacteria in intestinal tract, E.coli, disease stem bacteria, and other bacteria in the intestinal tract, It can kill staphylococcus, Escherichia coli, disease dry bacteria, salinophilic bacteria in the intestinal tract, etc.; 6, it enhances the function of liver and promotes the metabolism; 7, it expands the blood vessels, helps to reduce the blood pressure and prevents the occurrence of cardiovascular diseases; 8, it enhances the function of kidney, has the effect of diuretic and can reduce the content of urinary glucose; 9, it can make the body consume the fat into the body energy and promote the metabolism of sugar and protein, and prevent and control the obesity; 10, it contains the anticancer substance in the vinegar. Vinegar also contains anti-cancer substances. ● Vinegar can not regulate the pH value of blood Many people drink vinegar every day for health because they believe that vinegar is acidic in taste but alkaline food in the human body, so it can adjust the pH value of blood and make people less prone to illness. Under normal circumstances, human blood is weakly alkaline (about PH7.4). Nutritionist pointed out that there have been a few foreign studies found that people with alkaline blood are healthier, while those with acidic blood have a higher risk of disease, and there is also the so-called folk saying that eating meat will make the body acidic, and that eating vegetables, fruits, drinking vinegar, etc., can adjust the body and restore it to alkaline state. However, to change the pH value of the blood, really can rely on eating certain foods can do? Many Western nutritionists pointed out that there is no scientific basis to prove this claim, even Chinese medicine does not agree with the argument that dietary changes in the body pH value. Western nutritionists believe that the human body has its own mechanism to maintain the balance of blood pH value, which involves complex enzymes, I am afraid that not only by eating certain foods can change. Vinegar can not lose weight drinking vinegar diet was popular for a while, Japan, Taiwan has been popular in soybeans soaked in vinegar pickled into vinegar beans, claiming that every morning and evening to eat 10 to 20, can achieve weight loss. The argument is that vinegar can improve the body's metabolism, to prevent the accumulation of fat, but nutrition experts have shaken their heads and said that there is no definitive research to support this claim. A nutritionist reasoning, if you really want to say drink vinegar can lose weight, may be a lot of drinking vinegar drink full, can not eat other things, or to eat vinegar beans instead of the usual high-calorie snacks, relatively, calorie intake is reduced. However, this weight loss method can not last, long-term nutritional deficiency, unbalanced, greatly depleting health, Weng Hui-ling reminds that, on the contrary, some vinegar products such as fruit vinegar drinks will be added to a large number of sugar to enhance the taste, the calorie is not low, when you buy, you can pay attention to the ingredient list of whether there is a list of sugar or nutritional labeling of the calorie and carbohydrate content. So it is doubtful that drinking vinegar can help you lose weight. Vinegar is good for appetite The summer heat makes people lose their appetite, so eating some cool and sour dishes can stimulate your appetite. Seasoning with vinegar is one of the easy ways, such as using vinegar and olive oil to make oil and vinegar salad dressing with lower calories than Thousand Island dressing, using vinegar, minced garlic and chili pepper and other cold seafood, or using vinegar to pickle cucumber, lotus root, bitter melon, as an appetizer before summer meals. Dietitians suggest that patients with chronic diseases who have poor appetite and the elderly whose sense of taste has deteriorated should eat some vinegar in moderation to regulate their appetite and improve their eating. Vinegar can stimulate gastric acid secretion and help digestion Eating vinegar in moderation can be a little helpful for some people who originally have low gastric acid secretion, however, people with normal digestive tract function do not need to drink vinegar intentionally to improve digestion. Moreover, drinking vinegar for people with normal stomach acid secretion may not increase the amount of stomach acid secretion. Vinegar can prevent high blood pressure "less salt and more vinegar" is the traditional Chinese way of healthy eating, but the frequency of eating out, eat a lot of processed foods, modern people, salt intake has long exceeded the recommended amount of 6 grams per day. If you can make good use of vinegar to increase the flavor of dishes to reduce the use of salt, can indeed reduce the risk of hypertension, atherosclerosis, coronary heart disease, stroke and other diseases. In addition, fruit vinegar contains the mineral potassium, which can help the body discharge excess sodium, to prevent high blood pressure, of course, you eat fresh vegetables and fruits can achieve the same effect. Traditional Chinese medicine also uses vinegar to marinate peanuts as a food therapy to regulate blood pressure - soak peanut kernels in vinegar for more than 7 days, then eat 10-15 pills a day for more than a week. ● Vinegar can help with calcium intake When cooking rib soup, you can add a small amount of vinegar to help release the calcium from the bones, making it easier for us to absorb the calcium. After reading the above statements, it is not difficult to find that in fact, a lot of popular drinking vinegar health care method, most of the personal opinions, feelings, and scientific evidence is insufficient, in that case, we still need to eat vinegar every day, drink vinegar? Comprehensive expert opinion, in moderation, "eat vinegar" on the health of no harm. However, vinegar on the health of the help, in fact, as long as the diet balanced can be achieved, and not have to drink vinegar, so do not have to hold too high expectations of vinegar, and do not believe in the wrong prescription, that it can cure the disease. Every day drink vinegar or not, purely personal diet, health preferences, no habit of drinking vinegar people occasionally mix a cup of vinegar drinks, a change of flavor, as to add fun to life. It is important to remind the timing and amount of vinegar, eat improperly, but hurt your body. ● Do not drink vinegar on an empty stomach No matter how strong your stomach and intestines, it is not suitable to drink vinegar on an empty stomach, so as not to stimulate the secretion of too much gastric acid, which can harm the stomach lining. Drinking vinegar between meals, or an hour after a meal, is less likely to irritate the stomach and intestines, and helps with digestion. A small amount of vinegar is fine, but anyone who drinks a large amount of vinegar as if he or she has turned over the vinegar jar will cause too much irritation to the stomach and intestines. Moreover, fruit vinegar or other vinegar drinks on the market often add a lot of sugar, if you drink vinegar instead of water, tea and other beverages, adding a lot of extra calories, long-term drink, the chances of obesity greatly increased, and more unfavorable to the control of body weight. Vinegar health effects Vinegar, also known as bitters, is a commonly used cooking seasoning, but also a commonly used traditional Chinese medicine. In recent years, the role of vinegar in medicine and health care has been increasingly emphasized. Japanese folk have ten instructions for longevity, in which "less salt and more vinegar" is listed as the second one. Some people summarize that vinegar has four major health effects: one is lowering blood pressure and preventing arteriosclerosis; the second is sterilization; the third is preventing and eliminating fatigue; the fourth is moisturizing 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. Experiments have proved that general bacteria soaked in vinegar for 10 minutes will die, tableware soaked in vinegar for 130 minutes can kill bacteria causing food poisoning, and vinegar water solution can wash pesticide residues and radioactive dust on vegetables and fruits. Test results show that vinegar can protect vegetables containing vitamins from alkaline media and oxidative damage. China's growing ranks of the elderly in the osteoporosis patients gradually increased, has caused scientists to pay great attention. Calcium supplementation has become a top priority. The most important health effect of vinegar lies in the favorable absorption of calcium in the body. As we all know, 99% of calcium in human body exists in bones in the form of calcium salt, and only 1% of calcium exists in soft tissues, extracellular fluid and blood in the form of combined or free ionic state. The role of vinegar is to convert the insoluble calcium in food into soluble calcium, thus increasing the concentration of soluble calcium in the digestive tract and accelerating the absorption of calcium. Some people like to eat pig bone soup in order to replenish calcium. Clinical nutritionists of Zhongshan Medical University in Guangdong Province measured bone broth shows that the bone broth boiled for half an hour to 2 hours in a pressure cooker is far less than 100 grams of milk containing calcium 1/6, but if some vinegar is added to the bone broth when it is simmered, the amount of calcium contained in the broth can be increased by 10 times. Often vinegar also has a cosmetic effect, which is an important discovery in recent years. Now, vinegar has been used for wrinkle prevention, beauty, hair care, weight loss and so on. Frequent consumption of vinegar can enhance the function of human skin cells, delay skin aging, and gradually eliminate skin dark spots. The beauty recipe of Egyptian beauty Klipetui is to drink a small cup of vinegar (pearl vinegar) dissolved with pearl every day. Recently, American experts have suggested that the amino acids contained in vinegar can not only consume body fat, but also promote the smooth progress of metabolism such as sugar and protein, which can play a good role in weight loss. Of course, advocating "less salt and more vinegar" does not mean that you have to drink vinegar all day like water. Vinegar can be consumed directly, only a small glass of wine per day.
