Vinegar, also known as bitter wine, 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 benefits:
1, eliminate fatigue: rich organic acids can promote sugar 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.
