More on how milk negates the health benefits of tea

Milk Eliminates Cardiovascular Health Benefits Of Tea, Researchers Warn ScienceDaily 1/9/07 "There is a broad body of evidence from experimental and clinical studies indicating that tea exerts antioxidative, anti-inflammatory and vasodilating effects, thereby protecting against cardiovascular diseases. As worldwide tea consumption is second only to that of water, its beneficial effects represent an important public health issue. But, up to now, it’s not been known whether adding milk to tea, as widely practised in the UK and some other countries, influences these protective properties...Milk contains a number of different proteins: by testing each one separately, the researchers found that it was the three caseins that accounted for the inhibiting effect, probably by forming complexes with tea catechins...now in the process of comparing the effects of green and black tea on vascular function. “It’s an ongoing question whether green tea, with its higher catechin content, is superior to black tea in regard to endothelial function. In addition, because of the antiatherogenic potential of tea ingredients, we want to investigate the effects of the ingredients on chronic cardiovascular processes such as the development of restenosis (re-narrowing of arteries) after catheter procedures.”"
