Michael Greger, MD Biography

Former Director of Public Health and Animal Agriculture for the Humane Society
Con to the question "Is Drinking Milk Healthy for Humans?"

“Foods of animal origin in general naturally contain hormones, but cow’s milk may be of particular concern. The hormones naturally found even in organic cow’s milk may have played a role in studies that found a relationship between dairy products and human illnesses, such as acne, certain cancers, and male reproductive disorders. Milk consumption has also been associated with an increased risk of early puberty in girls and endometrial cancer in postmenopausal women.”
