According
to the results of a German research, there might be something to this. The
research found that drinking black tea had a significant effect on
artery dilation. The power of arteries to dilate, or expand, is very important
to the maintenance of simple blood pressure levels.
How can the consumption of black tea defend against high blood pressure? The researchers founded that molecular substances in black tea known as catechins assist to expand arteries by producing nitric oxide.
Interestingly enough, several British tea drinkers might be unknowingly giving up the heart health benefits of tea. How is this case? The german research team founded that adding milk to tea, the habit of most british tea drinkers, introduces caseins (caseins are proteins found in milk) that block the power of catechins to dilate blood vessels.
