Tea and Dairy Don’t Mix
A new study published in Europe shows that having milk with your tea totally negates the health benefits of drinking tea -- whether green, white, or black. It turns out that the casein in milk blocks the catechins in tea.
This is not only bad news for English tea drinkers who like to add a touch of milk to their tea, but it's also bad news for those of you who use green tea supplements while consuming dairy products (other than whey). It would seem that you're wasting your money.
