Black tea's purported cardiovascular benefits are blunted when milk, even skimmed milk, is mixed into the brew, found researchers here.
Researchers suspect that it may be the casein proteins in milk. Read my previous post on Dr. Loren Cordain's milk article to see more on why milk isn't an essential part of the human diet.

Unfortunately, cow milk is designed for baby cows, not humans. So a diet high in milk is also a diet high in the perfect dietary needs of baby cows.
