1, don't be hot
Lactic acid bacteria is a component of lactic acid bacteria milk, which has nutrition and health care effects on human body. Like most other bacteria, it is afraid of heat. If it exceeds 70 degrees, it is likely to be killed and lose its due nutritional value. Therefore, it is best not to heat lactic acid bacteria milk before eating, so that it can not only maintain its nutrients, but also taste the unique flavor of lactic acid bacteria milk. However, if the weather is too cold or children eat it, in order to prevent the discomfort caused by the low temperature of lactic acid bacteria milk, you can put the lactic acid bacteria bottle in a warm water basin and heat it for a few minutes, but pay attention to the fact that the water temperature should not exceed the body temperature of normal people, otherwise it will reduce the nutritional value of lactic acid bacteria milk.
2. Identify varieties
At present, there are many kinds of "milk yogurt" made of milk or milk powder, sugar, lactic acid or citric acid, malic acid, spices, preservatives, etc., which do not have the health care function of yogurt, so we should carefully identify them when buying.
3. Drink about 2 hours after meals.
Lactic acid bacteria milk should not be drunk on an empty stomach Usually, the PH value of human gastric juice is between pH 1-3, which is below 2 on an empty stomach, while the pH value of active lactic acid bacteria in lactic acid bacteria milk is above PH5.4. If you drink lactic acid bacteria milk on an empty stomach, lactic acid bacteria will be easily killed by gastric acid, and its nutritional value and health care function will be greatly reduced. If you drink lactic acid bacteria milk after meals, the gastric juice will be diluted and the PH value will rise to 3-5. This environment is very suitable for the growth of lactic acid bacteria, especially drinking lactic acid bacteria milk within 2 hours after meals, and the effect is the best.
4. Rinse your mouth in time after drinking
Yogurt is very corrosive to teeth, so rinse your mouth immediately after drinking it. With the development of lactic acid series drinks, the dental caries rate of children in China is also increasing, which is the leading role of some bacteria in lactic acid bacteria.
5, should not be taken with some drugs.
Antibiotics, such as chloramphenicol, erythromycin, sulfonamides and astringents for diarrhea, such as hypochlorous acid and tannic acid eggs, will kill or destroy lactic acid bacteria in yogurt and lose their nutritional and health care functions. When oral antibiotics are used to treat some inflammatory diseases, you can drink lactic acid bacteria milk at the same time, which not only supplements nutrition, but also avoids the side effects of antibiotics on human body. Lactic acid bacteria milk contains a large number of active bacteria, which can rebalance the imbalance of intestinal flora caused by antibiotics and protect gastric mucosa.
6. Drink before going to bed
Lactic acid bacteria milk not only contains many nutrients beneficial to human body, but also has many other functions. Drinking lactic acid bacteria milk before going to bed can not only give you rich nutrition of lactic acid bacteria milk, but also help digestion and soothe the nerves. Lactic acid bacteria milk not only has more nutrients than ordinary dairy products, but also inherits the sedative effect of ordinary dairy products. At the same time, lactic acid bacteria milk can effectively promote the digestive function of the stomach and help digestion through its numerous live lactic acid bacteria and slightly acidic unique ingredients.
7. Don't feed the baby.
Yogurt contains less calcium, and babies are growing and need a lot of calcium. Antibiotics produced by lactic acid bacteria in yogurt can inhibit and destroy many pathogenic microorganisms, but at the same time, it also destroys the growth conditions of beneficial bacteria on human body and affects normal digestive function, especially for infants with gastroenteritis and premature infants.
8. Buy yogurt from the refrigerator.
People who often drink yogurt will notice the instructions on the package that yogurt should be stored at 2℃ ~ 6℃. But we often find that many yoghurts in supermarkets are placed outside the refrigerator. There is no doubt that the temperature of yogurt outside the refrigerator has far exceeded 6℃ Then, if it is higher than the temperature of preserved yogurt, will the nutrition of yogurt be affected?
According to Wang Huaibao, vice chairman of China Dairy Association, the main component of yogurt is active lactic acid bacteria, which can prevent protein from fermenting and reduce intestinal gas production, thus alleviating symptoms such as abdominal distension and indigestion. Under normal circumstances, the survival period of active lactic acid bacteria is static in the environment of 0℃ ~ 4℃, but with the increase of environmental temperature, lactic acid bacteria will multiply and die rapidly. At this time, lactic acid bacteria beverage will become an acidic dairy product without living bacteria, and its nutritional value will be greatly reduced. Yogurt containing active lactic acid bacteria has a short shelf life, usually about two weeks, and must be stored at 2℃ ~ 6℃, otherwise it will go bad easily.
From this point of view, the yogurt placed outside the freezer in the supermarket no longer has the condition of refrigeration at 2℃ ~ 6℃, and the taste and nutritional value cannot be guaranteed. Therefore, consumers should not only look at the shelf life, but also look at the "temperature" when buying yogurt.
Yogurt is a long-lived drink.
According to Nobel Prize winner and Russian food expert Mechnikov (1845- 19 16), the earliest research results of yogurt prove that yogurt contains a growth active factor, which can enhance the body's immune function and is beneficial to health, disease resistance and anti-aging. There are many longevity places in the world, and residents have the habit of drinking yogurt for a long time. Some studies believe that Bulgarians live longer because they drink more yogurt, while the average height of Japanese people increases because they often drink yogurt. According to the research results of scholars, the reasons why yogurt is beneficial to human health and longevity may include:
1. Yogurt can enhance human immune function;
2. Reduce serum cholesterol level. Experiments have proved that even without any drugs. Drinking about 24 grams of yogurt per meal can reduce cholesterol after one week.
3. Regular consumption of yogurt can promote intestinal movement, shorten the transit time of food from mouth to anus, soften the contents of colon by glycolysis, increase the amount of fecal excretion, prevent constipation, and help prevent colon cancer. So yogurt is called "longevity food" abroad.
