Skimmed milk is a type of milk that has undergone a process of separation from fat, so that the remaining milk is low in fat and calories. It is obtained from cow's milk and is often used as a less oily alternative to other types of milk, such as whole milk or half-skimmed milk. Skimmed milk is rich in protein, calcium and vitamins, but it is less rich in fats and calories than whole milk. It is often used in cereals, smoothies, milk cafes and pastry recipes that require milk, but that do not want to add too much fat or calories. Skimmed milk is also often used by people who follow a restrictive fat or calorie diet or who have health problems that force them to limit their consumption of fat. However, it is important to note that skimmed milk can have a more bitter taste than whole milk because it contains less fat.
