Modern medicine believes that vinegar has the following functions in treating diseases and keeping in good 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. It has strong bactericidal ability, and can kill staphylococci, Escherichia coli, dry 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 the occurrence of cardiovascular diseases; 8, enhance kidney function, have diuretic effect, and can reduce urine sugar content; 9, can make the body's excessive fat into physical consumption, and promote the metabolism of sugar and protein, can prevent obesity; 10, vinegar also contains anticancer substances. ● Vinegar can't adjust the pH value of blood. Many people drink vinegar for health every day because they believe that although vinegar is acidic in taste, it is an alkaline food when it enters 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 pointed out that a few studies abroad have found that people with alkaline blood are healthier, while those with acid blood are at higher risk of diseases. There is also a saying among the people that eating meat will make their constitution sour, and eating vegetables, fruits, drinking vinegar, etc. can adjust their constitution and return to an alkaline state. However, can you really change the pH value of blood by eating certain foods? Many western nutritionists point out that there is no scientific basis to prove this statement at present, and even Chinese medicine does not agree with this argument that diet changes the body's pH value. Western nutrition believes that the human body has its own mechanism to maintain the pH balance of blood, which involves complex enzyme action, and I am afraid it can not be changed by eating certain foods alone. Low vinegar can't lose weight. Drinking vinegar to lose weight was once popular. It was popular in Japan and Taiwan Province to soak soybeans in vinegar and pickle them into vinegar beans, claiming that eating10 ~ 20 capsules every morning and evening can achieve weight loss. The argument is that vinegar can improve the body's metabolism and prevent fat accumulation, but nutrition experts shake their heads and say that there is no exact research to support this statement. Some nutritionists theorize that if you really want to lose weight by drinking vinegar, it may be that you are full of vinegar and can't eat anything else, or you replace the usual high-calorie snacks with jealous beans. In contrast, your calorie intake is reduced. However, this weight-loss method can't last long, which will lead to a lack of nutrition and imbalance in the long run, which will greatly consume health. Weng Huiling reminded that on the contrary, some vinegar products such as fruit vinegar drinks will add a lot of sugar to enhance the taste, and the calories are not low. When buying, you can pay attention to whether sugar is listed in the ingredient list, or whether the calories and carbohydrate content marked by nutrition are included. Therefore, it is doubtful whether drinking vinegar can lose weight. ● Vinegar can stimulate appetite. The sultry summer makes people lose their appetite. Eating some cool and sour dishes can stimulate their appetite. Seasoning with vinegar is one of the simple methods, such as making oil-vinegar salad dressing with lower calorie than Thousand Island Sauce with vinegar and olive oil, cold seafood with vinegar, minced garlic and pepper, or pickling cucumber, lotus root and bitter gourd with vinegar 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 eating situation. ● Vinegar can stimulate gastric acid secretion and help digestion. A moderate amount of jealousy is helpful to some people who have less gastric acid secretion. However, people with normal digestive tract function do not have to deliberately 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. However, modern people who eat out frequently and eat a lot of processed food have long 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 excrete excess sodium and achieve the purpose of preventing hypertension. Of course, you can achieve the same effect by eating fresh vegetables and fruits. 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 ingest calcium. When cooking ribs soup, you can add a small amount of vinegar, which will help release calcium in 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 health care methods of drinking vinegar are mostly personal opinions and feelings, but scientific evidence is insufficient. In this case, do we still need to be jealous and drink vinegar every day? According to experts, a moderate amount of "jealousy" is not harmful to health. However, the health benefits of vinegar can actually be achieved as long as the diet is balanced, and it is not necessary to drink vinegar. Therefore, there is no need to hold too high expectations for vinegar, let alone mistakenly believe 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 drink 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. Eating inappropriately will hurt your health. ● Do not drink vinegar on an empty stomach. No matter how strong your stomach and intestines are, it is not suitable to drink vinegar on an empty stomach, so as not to stimulate the secretion of too much stomach 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, it's okay to be jealous in a small amount, but anyone who drinks a lot of vinegar like a jealous jar is too irritating to the gastrointestinal tract. Moreover, a lot of sugar is often added to fruit vinegar or other vinegar drinks on the market. If vinegar is used instead of boiled water, tea and other drinks, a lot of calories will be added. If you drink it for a long time, the chance of obesity will increase greatly, which is even more unfavorable for weight control.
