5 Why is it easier to digest sour milk than fresh milk?​
Katyanochek1 [597]

Sour milk contains less lactose than the fresh milk, as the sour milk gets converted to lactic acid and bacteria which enhances the digestion process. One important reason is that proteins take more time in getting digest than other nutrients. We know that fresh milk has a large amount of lactose.

Explanation:

The lactic acid bacteria have many benefits. They improve lactose digestion in the stomach. The lactase activity of the bacteria performs  the task of digesting lactose in the product once it reaches the intestine thus fuelling the process of digestion in case of sour milk.

In fresh milk, the casein protein in contact with milk forms curdles which are difficult to digest.
