Foods generally have a shelf life and may spoil after the shelf life, so it is not recommended to drink yogurt when it is expired. Yogurt itself is fermented, and the fermentation of expired yogurt will be more powerful, the number of probiotics is reduced, and harmful bacteria multiply. Not only does expired yogurt taste bad, drinking expired yogurt may cause diarrhea, vomiting, abdominal pain and other discomforts. Note that not only expired yogurt is not recommended to drink, other food expired is also not recommended to eat, but normal yogurt can be drunk in moderation, the nutritional content of yogurt is very high, rich in protein, calcium, etc., such as 100g of yogurt contains 118mg of calcium, 150mg of potassium, which can be supplemented for the body’s energy and minerals, and the sweet and sour taste brought by its beneficial bacteria also helps to open the stomach. Those who are allergic to dairy products should not consume yogurt.
