Cheese is a dairy product produced in a range of flavors, textures, and forms by coagulation of the milk protein casein. It comprises proteins and fat from milk (usually the milk of cows, buffalo, goats or sheep).
Cheese is a nutrient-dense dairy food, providing protein, fats, and minerals. Some hard block cheeses that contain little moisture like Parmigiano-Reggiano and aged cheddar are easily stored and travel well because they do not require refrigeration.
