1, keep food nutritious
In acidic environment, vitamins C and B in food are relatively stable and are not easily destroyed by high temperature or air oxidation. Plant food is rich in iron, and a small part of it is reduced to ferrous ions after entering the body, which is absorbed by the small intestine. Vinegar can stimulate the secretion of gastric acid, which is beneficial to the absorption of iron. When eating fried and barbecue foods, adding proper amount of vinegar can eliminate some oil oxidation products and improve food safety.
2. Delay the rise of postprandial blood sugar level.
Studies have shown that moderate jealousy can reduce postprandial blood sugar, especially for pre-diabetic patients. There are two reasons. First, the acetic acid contained in vinegar can inhibit the activity of amylase and delay the decomposition of starch into glucose. Second, acetic acid can delay gastric emptying and weaken the speed of blood sugar reaction.
Many people are used to drinking vinegar directly or adding too much vinegar to food, which will stimulate oral mucosa and esophageal mucosa and induce inflammation and ulcer; At the same time, it will also change the pH value of gastric juice, damage gastric mucosa, and then cause nausea, vomiting and stomachache, which can induce acute gastritis in severe cases; Drinking too much vinegar can also lead to excessive sodium intake and affect blood pressure control.
1, which can prevent cancer
There are a lot of polyphenols in vinegar, which belong to antioxidants and can play a certain antioxidant role. Antioxidants can protect whole body cells from oxidative stress, which may stimulate tumor growth. However, vinegar can inhibit the growth of cancer cells, and this effect is only shown in cell and mouse experiments, and there is not enough research on whether it is effective for human body.
2, can soften blood vessels
Vinegar will not soften blood vessels, because arteriosclerosis is caused by lipid deposition and inflammatory reaction, and acetic acid does not affect blood lipid level and inflammation. Moreover, the vinegar eaten does not enter the blood vessels, but is absorbed in the small intestine. It is a small amount of acetic acid that is eliminated by the immune system, which can't soften blood vessels at all.
Step 3 lose weight
Drinking vinegar can really promote food digestion, but it will not dissolve the stored fat, and the weight loss effect is minimal.
Step 4 kill parasites
Some people are used to dipping in vinegar when eating sashimi or raw shrimp, thinking that this can kill parasites, but it is not. No matter what seasoning can kill parasites or bacteria, the best way is to cook at high temperature.
Step 5 treat beriberi
Some beriberi patients often soak their feet with vinegar, but it has little effect. Instead, it destroys the sebum layer, reduces the skin resistance, further aggravates the beriberi problem, and even induces contact dermatitis.
skill
It can be seen that vinegar can't treat or prevent some diseases at all, but a small amount of vinegar is harmless to the body. When cooking foods containing vitamin C, you can add a few drops of vinegar to avoid the loss of vitamin C; When cooking vegetables containing anthocyanins, such as purple cabbage or spinach, vinegar may be added to make the food more beautiful and prevent the color from turning blue or black.
