It is the amount of the saturated fat, hormones and cholesterol (and antibiotics and so on) in three glasses that is the important thing. Many people drink at least one glass of milk and put at least one glass on their cereal too. And then they eat cheese on a lot of their food, which is concentrated and contains a lot more of everything than milk does, so many people consumes a lot more than what is in three glasses of milk every single day.
