As this article states, there is a very heated debate on the merits of raw versus pasteurized dairy products. We all know that milk is one of the healthiest, most complete foods out there (though a good argument could be made for the egg as well).
sites abound to encourage you onto this new/old nutritional bandwagon.
As with all good conspiracy theories and "cult mentality" encouragements, there is some truth in the claims made by raw milk advocates. Citing old scientific articles on the husbandry of dairy cattle and the evils of "factory farming," raw milk advocates will have you believe that pasteurization was developed purely to cover-up the mistakes and mishandling of milk products from unfeeling capitalists who want to destroy the family farm.
Let's look at milk: it is a natural blending of protein, calcium and other nutrients that provides everything a body needs, especially a mammalian one. True, it has been consumed safely for years prior to pasteurization and even refrigeration, but the reason for that wasn't because it was a healthier product.
The reason for that is because more people lived on the farm or within an easy buggy ride of one. As industry was revolutionized, cities grew and town mice and country mice moved farther away from each other. There was a need to develop ways to feed people. Refrigeration and pastuerization were two of the inventions that made city-life possible, and allowed people who lived far away from the farm to have wholesome food. Many of the people who died from unpastuerized milk in days gone by were children, and statistics on those deaths are shady at best.
And, as untasteful as it may be to most of us, the rise of the factory farm has lead to consistent, cheap, wholesome food that can feed more people. And then there is the "organic food" craze. Both of these are topics that I'll need to cover some other time.
If I need to list more reasons not to consume raw milk, you are a much braver soul than I.
