From the chemical composition analysis of vinegar, its main components are acetic acid, non-volatile acid, amino acid, sugar and so on. Therefore, vinegar has the functions of disinfection and sterilization, reducing spicy taste and protecting vitamin C in raw materials from less loss. It can also help digestion, improve the acidic environment in the stomach and inhibit the reproduction of harmful bacteria. Therefore, proper jealousy is good for human health. However, the first condition of good health is to keep the organs working normally. When drinking a large amount of vinegar, a large amount of vinegar will enter the human body, change the PH value of gastric juice, strengthen the acidity in the gastric environment, and cause damage to the gastric mucosa. A large amount of vinegar consumed by healthy people can cause stomach pain, nausea, vomiting and even acute gastritis; A large amount of vinegar consumed by gastritis patients will aggravate the symptoms of gastric diseases, and people with ulcers can induce ulcer attacks. At the same time, the absorption of acetic acid will also affect the acid-base balance of the whole human body. This is because under normal circumstances, the pH value of human blood and body fluids should be kept between pH 7.35 and 7.45, which is weakly alkaline. The intake of acidic and alkaline foods will affect the pH of blood and body fluids. Physiologically speaking, too much acidic food will lead to an increase in the acidity of blood and body fluids, resulting in acidosis. The human body is acidic and will feel unwell, tired and listless in a short time. If you are in the state of polybasic acid for a long time, it will cause electrolyte disorder in the body and easily induce neurasthenia, arteriosclerosis, hypertension and coronary heart disease.

Vinegar has a good cosmetic effect and has a long history in China. This is because vinegar is rich in active substances such as acetic acid, protein and amino acids, which can promote skin metabolism, reduce lipid peroxide in the body, delay skin aging and make skin bright and beautiful.

Vinegar enjoyed the reputation of "God of Food" in ancient China. Li Shizhen, a medical scientist in Ming Dynasty, said in Compendium of Materia Medica: "Vinegar can reduce swelling, dispel dampness, kill pathogens and poison, and manage various medicines". Japanese scientists believe that the health care function of vinegar mainly has the following four aspects: First, vinegar can prevent and relieve fatigue. People feel tired after exercise, and jealousy can make their physical strength return to normal quickly. Second, constant jealousy has the effect of lowering blood pressure and preventing arteriosclerosis. Third, vinegar has bactericidal effect on pathogenic bacteria. Fourth, vinegar is good for beauty. Wash your face and put more vinegar or a few drops of vinegar in the bath water to moisturize your skin. British scientists have found that being jealous can improve intelligence. Vinegar is an alkaline food, and the acidity of human brain is related to IQ.

It is no wonder that vinegar is popular in the United States, Japan and other countries because of its magical health care effect. According to statistics, the average vinegar in the United States is 6.5 1 kg, while that in Japan is 7.88 kg, while that in China is only about 3.5 kg. For the sake of health, from the perspective of high IQ, and for the sake of beauty and moisturizing, I suggest you be jealous.
