Friendly Farms Whole milk is a form of milk that has a larger percentage of milk fat than other types of milk. Full-fat milk is another name for it. The word "whole" means that the milk has not been defatted and is sold with its natural fat content intact. Whole milk is frequently used to add richness to foods in cooking and baking, and it is also drank on its own or with cereal. While whole milk has more saturated fat, it also contains key minerals such as calcium, vitamin D, and protein.
