Q. I’ve read that drinking tea with milk has a negative effect on human blood vessels. Is this true?
A. A German study showed recently that drinking two cups of black tea relaxes blood vessels, quadrupling blood flow (European Heart Journal, Jan. 9, 2007). But adding milk to the tea counteracts this benefit. So, drinking tea with milk is not bad for you, but it isn’t as good for you as drinking your tea black.
