Yogurt is not spoiled milk. It is produced by fermenting milk with live bacterial cultures. The fermentation process produces lactic acid, which gives yogurt its tangy flavor and thick texture.

Some potential benefits of yogurt for the human body include:

1. Probiotics. Yogurt is a good source of probiotics, beneficial bacteria that promote a healthy gut microbiota. A healthy gut microbiota is associated with improved digestion, improved immune function, and potential protection against certain diseases.

2. Rich in nutrients. Yogurt is rich in important nutrients such as calcium, protein and vitamins B12 and B2. These nutrients are important for bone health, muscle function and overall well-being.

3. Digestive health. The live bacterial cultures in yogurt can help maintain a healthy balance of gut bacteria, which can improve digestion and reduce symptoms of digestive disorders such as bloating, gas and diarrhea.

4. Weight control. Some studies suggest that including yogurt in a balanced diet may help control weight and reduce the risk of obesity. The protein and probiotics in yogurt can help promote feelings of fullness and reduce cravings for unhealthy foods.

Overall, yogurt can be a nutritious and tasty addition to a healthy diet. However, it is important to choose simple, unsweetened varieties to avoid added sugar and other artificial ingredients.
