China is the first country in the world to brew vinegar from grains, and there were written records about vinegar as early as the 8th century BC. By the Northern and Southern Dynasties, the production and sales of vinegar had been very large. The important book Qi Yao Min Shu handed down at that time systematically summarized the experience and achievements of working people in vinegar making from ancient China to the Northern Wei Dynasty.

Vinegar is the crystallization of China people's hard work and wisdom for generations, and it has a strong fragrance in China's food culture.

"Four Benefits" of Vinegar

Ha, Dr. Yu is jealous, and he is jealous.

Vinegar itself contains nutrients beneficial to human body, such as 18 amino acids synthesized in protein, glucose, fructose, maltose and rich inorganic elements (such as calcium, iron, phosphorus, etc. ), are essential components in the process of human metabolism. Vinegar is the most popular of all condiments. To sum up, vinegar has four advantages:

1. Vinegar can improve taste and appetite.

Vinegar has a certain effect on regulating appetite. The simplest seasoning method is to use cold dishes such as vinegar, soy sauce and minced garlic. Eating some side dishes mixed with vinegar before meals has a good appetizing effect on people with bad appetite. Especially for patients with chronic diseases and elderly people with degraded taste, vinegar can change their poor appetite, and the effect is more obvious.

In addition, vinegar can also stimulate gastric acid secretion, thus achieving the purpose of promoting digestion. Vinegar is very helpful for people with low gastric acid secretion, but people with normal digestive tract function do not need to drink vinegar to improve digestive function.

2. vinegar can "reduce salt"

Using vinegar to improve the taste of food is much healthier than using salt. Cooking with less salt and more vinegar is a healthy eating habit.

Eating too much salt is not only harmful to the body, but also makes people's taste more salty, and other foods will be eaten more. The more water you drink, the more weight you gain. For people who love salty taste, it is advisable to add some vinegar to their dishes. More vinegar and less salt will not only make them not salty enough, but also make them more delicious and healthier.

Introduction to the book "Did you eat right? This book is the result of cooperation between Professor Yu Kang and Yue Yue, the host of Yangshengtang, and every word is carefully thought out.

This book revolves around "Did you eat right?" This health theme that people are most concerned about and have the most general needs can be described as a comprehensive summary of Professor Yu Kang's 20 years of medical nutrition and health work.

3. vinegar can inhibit bacteria

Vinegar contains 0.4% ~ 0.6% acetic acid, which can inhibit the growth and reproduction of many germs to some extent. Therefore, when local bacterial and viral diseases are prevalent, people can add proper amount of vinegar when cooking and mixing cold dishes, which can stimulate appetite and inhibit bacteria, which can be said to be "killing two birds with one stone".

4. vinegar can relieve boredom.

Vinegar is a good food, which can remove fishy smell and get tired. For example, when cooking aquatic products or animal viscera such as belly, intestine and heart, vinegar can eliminate the fishy smell and peculiar smell of food. Some raw materials with heavy fishy smell can be soaked in vinegar in advance, and at the same time, some oil attached to the surface can be removed.

Recognize the misunderstanding of vinegar

After eating vinegar for so many years, I really didn't know that vinegar was so magical that even bacteria could be killed. Vinegar has a certain antibacterial effect, but it is really beyond vinegar's endurance. If this were true, there wouldn't be so many flu. In fact, the main function of vinegar is seasoning and appetizing. As for other "influences" ... let vinegar have a good rest.

Jealousy can't soften blood vessels

The saying that vinegar can soften blood vessels and lower blood pressure has been circulating among middle-aged and elderly people for a long time, but this is a wrong understanding.

Vinegar can dissolve calcium, but atherosclerosis is not just a simple calcification problem. Atherosclerosis refers to the formation of atherosclerotic plaques in blood vessels, which reduces the elasticity of blood vessels. It is unscientific to soften blood vessels simply by jealousy. Acetic acid itself is weak and cannot play the above-mentioned "role" in the body. At present, there is no research at home and abroad to prove or suggest that "vinegar" has the above "function".

There are many ways to keep blood vessels healthy, such as light diet, less greasy food, more exercise, quitting smoking and limiting alcohol. Maintain the elasticity of blood vessels by lowering blood lipids.

Jealousy can't lose weight.

Drinking vinegar to lose weight is all the rage. Soak soybeans or black beans in vinegar and pickle them into vinegar beans. It is claimed that eating 10 ~ 20 capsules every morning and evening can achieve the effect of losing weight. It is said that vinegar can improve the metabolism of the body and prevent fat accumulation, but there is no scientific experiment to support this statement. If you really want to lose weight by drinking vinegar, unless you drink a lot of vinegar and can't eat anything else, or replace your usual high-calorie snacks with vinegar beans, by contrast, your calorie intake will decrease.

However, this method of losing weight is unsustainable, which will easily lead to nutritional imbalance and even damage the stomach and intestines, which is harmful to health. On the contrary, if you drink some vinegar drinks, you may get fat. Some vinegar drinks will add a lot of sugar to improve the taste, and the calories are not low. When buying, pay attention to whether sugar is listed in the ingredient list, and the carbohydrate content and calories marked on the product.
