Yogurt is out of date and can't be drunk. As we all know, the process of making yogurt is the process of fermentation, so many people will think that the expired yogurt is just a more serious fermentation, but it is not. To be sure, expired yogurt is inedible because:

1, after the expiration of yogurt, the number and activity of live bacteria in it will decrease, or even die completely. In this sense, the function of yogurt in regulating intestine has basically disappeared.

2. Although the calcium and protein in yogurt will not disappear because of the expiration of yogurt, eating expired food will have adverse effects on human intestinal health.

3. Pasteurization is used in the process of yogurt production, which can not completely sterilize. Once the yogurt expires, it will lead to the rapid growth of harmful bacteria. Therefore, once the expired yogurt is drunk, it is easy to cause intestinal flora disorder, and the common consequence is abdominal pain and diarrhea. In severe cases, it is likely to cause intestinal poisoning and even threaten life safety.

Extended data:

Yogurt is a good dairy product. This "good" is not because of the so-called "probiotics"-it is emphasized that it is just the marketing selling point of the merchants, and its effect is not as great as what they say. Perhaps it can only be said that "talking is better than nothing". The "shelf life" selected by the manufacturer is mainly based on the change of flavor and taste. No matter whether it has expired or not, the flavor and taste always get worse during storage. For consumers, there is really no need to worry about how many live bacteria are left-even during the shelf life, it is better to buy less yogurt every time, and it is better to eat it as soon as possible.

Use of expired yogurt

1 and hair care

Expired yogurt also has a good nourishing effect on human hair. Yogurt contains a lot of lactic acid and alkaline substances. Usually, when washing your hair, put expired yogurt on your hair and gently rub it to reduce hair damage and make your hair more supple and smooth. In addition, expired yogurt can also be used as a conditioner at ordinary times, which can prevent hair from drying and splitting and turning white.

2. Wipe the leather shoes
