The production process of yogurt is the process of fermentation, so many people will think that expired yogurt is just a more serious fermentation, but it is not. To be sure, expired yogurt is inedible because:
1. After the yogurt expires, 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 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 production of yogurt, which can't be completely sterilized. 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.
