Can whole milk into two per cent milk by adding water?

No, adding water to whole milk will not create two percent milk in terms of nutritional content. Two percent milk is specifically processed to have a certain fat content, which is achieved by removing some of the fat from whole milk. Simply diluting whole milk with water will reduce its fat concentration but will also dilute other components like proteins, vitamins, and minerals, resulting in a product that is not equivalent to commercially produced two percent milk.
