*this is my personal opinion; I am not a medical professional, and this is not meant to be advice*
I have read that raw milk is better for a person than the pasteurized, homogenized, killed dead milk we buy in the grocery store. I have recently read that pasteurization and homogenization, in addition to killing all the beneficial bacteria and enzymes in the milk, actually alter the chemical and protein structure of the milk on a cellular level, and this may mean any number of harmful outcomes. Some researchers even believe that processed milk could be partly responsible for some cases of diabetes and cancer. (Health 101 Article, Homogenization; Raw Milk: Good For you?)
At the same time, we are told that raw milk is dangerous and that we should all avoid it. How is it that we are so easily convinced that raw milk is dangerous? Our grandparents and ancestors beyond that generation drank raw milk, and they were healthy and vigorous, hard working people.
Some bacteria are beneficial and good for us. Our bodies need beneficial bacteria, and we need to encounter some things that are not so good for us so that our natural immune response can be triggered and we can be strong and healthy. Didn't we all learn that in high school biology? Having an illness and getting through it makes our bodies stronger? It is the way nature intended. We were created to live in harmony with our natural world, and to adapt and gain strength from natural elements.
There are benefits and dangers in everything we do in life. (The Benefits and Dangers of Raw Milk) There are dangers in buying packaged spinach, tomatoes, and some meats at the supermarket. Likewise, there are benefits and dangers in drinking raw milk. It is important to know the source, to know the animal, and to know that the animal is healthy and the environs of the animal are clean.
I am a believer in the benefits of raw milk. And having tasted it for myself (from a goat), I can tell you that it has more body and creaminess than any milk I have ever had from the supermarket.
