I'm very suspicious of food that doesn't spoil. Milk heated to the high temperatures of UHT denatures proteins and, IMO, harms the lining of the the gut. Sure, the milk may have come from cows raised according to organic standards, but the treatment renders it an unhealthy product. The best milk is consumed raw, fresh or fermented. Unfortunately, our politicians have made it illegal to sell raw milk in most states.

Here is a little bit from the book, Nourishing Traditions: The Cookbook that Challenges Politically Correct Nutrition and the Diet Dictocrats by Sally Fallon & Mary G. Enig. On page 252, they quote William Campbell Douglass, MD:

"There's another phony milk that you should know about. It's called UHT milk. The dairy industry is producing this one in attempt to regain business lost to filled milk and other junk beverages. UHT stands for ultra high temperature. What it means is that milk has been heated to such a high temperature that it is sterilized, just like surgical instruments. It can be shipped in unrefrigerated trucks--a tremendous savings to the dairymen. It will sit on a shelf, unrefrigerated, for months without spoiling. The reason it won't spoil is because no self-respecting bug will eat it. Bugs are smart. They like fresh food with nutrient value, not steam-cleaned pseudofood."

The best milk is consumed raw, fresh or fermented. Unfortunately, our politicians have made it illegal to sell raw milk in most states. I'm in Tennessee and we had people lobbying about 2 years ago, trying to persuade our politicians to make raw milk legal. It wasn't a success, but I'm not giving up hope. Right now, California needs people to send emails, letters and make calls so that buying/selling raw milk continues to be legal.
