Yogurt can enhance human immune function. Regular consumption of yogurt can promote intestinal movement, shorten the time of food mouth-to-anus transport, soften and ferment colon contents, increase fecal excretion, prevent constipation and prevent colon cancer. Therefore, yogurt is known as longevity food abroad. Drink the most standard before going to bed. Why not drink yogurt on an empty stomach? Why not drink yogurt on an empty stomach? This is because the PH of human gastric juice is usually between pH1-3, and the pH of fasting is below 2, while the pH of active lactic acid bacteria in yogurt is above 5.4. If you drink yogurt on an empty stomach, lactic acid bacteria will be easily killed by gastric acid, and their nutritional value and health care function will be greatly reduced. If you drink yogurt after a meal, 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 if you drink yogurt within 2 hours after a meal, the effect is the best. Yogurt can't be heated. Once the yogurt is cooked and heated, a large number of active lactic acid bacteria will be killed, and its physical properties will also change, resulting in separation and precipitation, and the unique taste and taste of yogurt will disappear. The most valuable thing in yogurt is the lactic acid bacteria, which can not only decompose lactose in milk to produce lactic acid, increase the acidity of intestinal tract, but also inhibit the growth of spoilage bacteria and weaken the toxin produced by spoilage bacteria in intestinal tract. If yogurt is heated, the lactic acid bacteria in yogurt will be killed, and its nutritional value and health care function will be reduced. Therefore, drinking yogurt cannot be heated, so it is advisable to buy it now in summer and drink it at room temperature in winter. Rinse your mouth with boiled water after drinking. 2 Some strains and acidic substances in yogurt are harmful to your teeth. For children, if they don't gargle after drinking yogurt, they are particularly prone to dental caries. You can't take medicine with yogurt. Taking medicine with yogurt instead of boiling water is an incorrect habit and should be corrected. In particular, you can't take chloramphenicol and erythromycin with yogurt. Antibiotics such as sulfanilamide and some drugs for diarrhea, because these drugs will also destroy or kill lactic acid bacteria in yogurt. Yogurt is a product made from fermented milk, which not only has the nutritional value of milk, but also contains beneficial microorganisms such as lactic acid bacteria, which can inhibit spoilage bacteria in human intestines and promote the digestion and absorption of nutrients. It is a nutritious food suitable for all ages. It is not suitable to drink yogurt on an empty stomach, and the pH value suitable for the growth of lactic acid bacteria is below 5.4. On an empty stomach, people's stomach acid is higher, and the pH value is below 2. After meals, the gastric juice is diluted, and the pH value rises to 3.5. Therefore, drinking yogurt on an empty stomach is easy to kill lactic acid bacteria, and the health care effect is weakened, but drinking it two hours after meals has a better effect. Active lactic acid bacteria in sour milk, which should not be heated, are beneficial and harmless to human body. It can decompose lactose in fresh milk to produce lactic acid, increase the acidity of intestinal tract, inhibit the growth of spoilage bacteria and weaken the toxin produced by spoilage bacteria in intestinal tract. In addition, active lactic acid bacteria also have the function of enhancing gastrointestinal digestion. After heating and boiling, not only the unique flavor of yogurt disappears, but also the beneficial bacteria in it are killed, and the nutritional value is greatly reduced. Babies should not be fed with yogurt. In modern families, it is often seen that parents feed their babies with yogurt. In fact, this practice is unscientific. Although yogurt can inhibit and eliminate the growth of pathogenic bacteria, it also destroys the growth conditions of beneficial bacteria groups for infants and affects normal digestive function. People who drink milk and have bloating can drink yogurt. Some people will produce gas in their stomachs after drinking milk, and feel bloating and even diarrhea. This is because these people lack lactobionic acid, and lactose in milk cannot be decomposed by glycosidase in the small intestine, that is, it enters the large intestine and is fermented by other bacteria in the large intestine to produce gas. However, these people will not have the above phenomenon when drinking yogurt, because the lactic acid bacteria in yogurt have decomposed lactose in milk during fermentation and converted it into sugars that are easily absorbed by the human body. So people who drink milk and have bloating can drink yogurt. Do you know yogurt? Exploring the history of yogurt can be traced back more than two thousand years! Until 1908, Russian Nobel Prize winner Chinikov obtained the secret of Bulgarians' longevity-drinking yogurt often through a lot of research. The definition of the World Health Organization and the United Nations Food and Agriculture Organization is that fresh milk is used as raw material, pretreated and then inoculated with pure cultured Lactobacillus bulgaricus and Streptococcus thermophilus as starter, and kept for a certain period of time. The finished product of casein coagulation due to lactic acid production is called yogurt. Yogurt is divided into solidified yogurt and stirred yogurt according to its form. According to the fat content, it is divided into high-fat yogurt, full-fat yogurt, low-fat yogurt and skim yogurt. According to the different raw materials used in production, yogurt can be divided into pure yogurt, flavored yogurt and fruit yogurt. The nutritional structure of yogurt is closest to the ideal nutritional dietary standard. It is rich in calcium, high-quality protein, vitamins and carbohydrates, and low in calories, so it can improve the body's disease prevention ability and regulate intestinal function and immune system. Lactic acid bacteria in yogurt can enhance digestion and absorption, gastrointestinal peristalsis and substance metabolism of the body. Jan Roland, head of the Northern Ireland Diet and Health Center, also pointed out that every bottle of yogurt can not only reduce the increase of colon cancer, but also help the human body excrete toxic substances. Yogurt and milk can be said that yogurt is "shine on you is better than blue". In the fermentation process, except that most of the lactose in pure milk is converted into lactic acid, other nutrients are no different from milk. For patients with lactose intolerance, drinking yogurt can avoid abdominal distension and diarrhea caused by lactose intolerance. Yogurt beauty says that in addition to the health care function of diet therapy, yogurt can also be used for external use. The vitamin A, carotene, B vitamins and vitamin E contained in yogurt can prevent the oxidation and decomposition of unsaturated fatty acids in human cells, prevent skin from keratinization and dryness, and keep skin moist, delicate, elastic and full of luster. Among many natural beauty materials, yogurt is one of them, and it is better not to contain additives. Yogurt can also be used for hair care, because vitamin A, vitamin B 1, methionine and cystine contained in yogurt can prevent hair loss and promote hair regeneration.
