Drinking black tea has been proven to be effective in reducing heart health issues. But, recent research information about black tea shows that adding milk to black tea produces a negative cardiovascular effect.

As reported in the European Heart Journal, a study completed in Berlin at the Charite Hospital Universitatsmedizin showed that the cardiovascular benefits offered by black tea were negated when drinking black tea with milk added.

Although this was a scientific study, it should be noted that the test base was small. The study was based on 16 women drinking black tea on three separate occasions. With that said, it is information that should be taken into consideration when deliberating the health benefits of drinking black tea.
