Yogurt is a dairy product made of fresh milk or reconstituted milk and fermented by lactic acid bacteria.
Stirred yogurt is a little thinner than solidified yogurt, but it has a better flavor because of the addition of fruits, jams and other ingredients. Yogurt not only has all the nutrients of fresh milk, but also has obvious medical and health care functions.
The difference between yogurt and lactic acid beverage is that yogurt is fermented by lactic acid bacteria, and the content of protein (2.7%-
2.9%) is the same as fresh milk, and lactic acid beverage is a kind of beverage made from fresh milk or dairy products, adding water, sugar solution and sour agents (citric acid, lactic acid, etc.). ), its protein content is below 1%. Therefore, the nutritional value of lactic acid beverage is far less than yogurt.
Drinking yogurt "four is not suitable"
It is not advisable to drink too much.
Many people think that yogurt has high nutritional value and contains Lactobacillus acidophilus, which is beneficial to health. I think drinking more is beneficial and harmless. In fact, drinking too much yogurt will cause a temporary surplus of some nutrients, and may lead to metabolic disorders, especially the excessive intake of Lactobacillus acidophilus, which will lead to the imbalance of the original microbial flora in the intestine, thus causing some intestinal diseases.
Not suitable for cooking.
Lactobacillus acidophilus in yogurt is a living bacterial nutrient. If boiled, live bacteria will become dead bacteria, making bacteria lose their unique health care function. Of course, don't take it with boiling water, so as not to kill Lactobacillus acidophilus or reduce its vitality.
It is not advisable to drink on an empty stomach.
The survival of Lactobacillus acidophilus is closely related to the PH value in the gastrointestinal tract. According to the results of bacteriological culture test in medical research department, Lactobacillus acidophilus grows and reproduces well in the environment above PH 5.4, but it is difficult to survive below PH 2. For example, if you drink yogurt on an empty stomach, the PH value of gastric juice is generally around 2, and Lactobacillus acidophilus will be killed or its vitality will be seriously reduced, thus failing to achieve the health care effect that yogurt should have. Therefore, the best time to drink yogurt should be within 2 hours after meals. At this time, the PH value of gastric juice has generally risen to about 5, which is more suitable for the survival and growth of Lactobacillus acidophilus, thus contributing to its unique health care function.
It should not be taken with medicine.
It is best not to take medicine before and after drinking yogurt, especially antibiotics such as erythromycin, chloramphenicol and sulfonamides, so as not to kill Lactobacillus acidophilus in yogurt or reduce its vitality. Similarly, it is best not to drink strong tea before and after drinking yogurt.
