People should have correct facts so that they can make informed decisions, and unfortunately, there is more fear than fact in the author's post. There is no connection between leukemia and cow's milk and formula. Even if it is, the US Government has rigorous standards for subsidized products, of which milk is one. Even with the regulations, the US Government allows a margin of leeway into many of the foods we eat or drink. The Department of Health's allowances are surprising, such as insect matter in cereal, etc, etc, but such allowances are made.
Milk tastes quite good to the vast majority of the world, especially when chocolate syrup is added.
To some people, however, the taste may be unpleasant, and of course, then, seeking an alternative beverage may be a good idea. Those of us who enjoy the taste of milk will probably continue to drink it, however. That is a disturbing image. Milk is for infants, and should only come to them from another of their species. Well, I can also visualize a person biting off the head of a chicken and drinking its blood, but this doesn't happen often.
