There are a number of myths about this. For example. . . There is absolutely no evidence to support the contention that raw milk is more nutritious than pasteurized milk. Pasteurized milk does not contain any chemical additives. In fact, chemical additives are prohibited by law.
Raw milk can contain many disease-causing organisms.
There is no scientific evidence that raw milk makes you more resistant to disease. There is no scientific evidence that raw milk better promotes the development of teeth. Some people may say they have grown up drinking raw milk and never suffered any ill effects. However, public health authorities have documented many cases of illnesses caused by drinking raw milk which tell a far different story. And, while mandatory pasteurization of milk has virtually eliminated large outbreaks of milk borne disease in Canada, occasional cases still remind us of the hazards of raw milk consumption.
