A new research on cardiovascular diseases has proved that the drinking of just one cup of black tea everyday might protect against cardiovascular disease.
According to the study that was conducted at the University of L'Aquila in Italy and supported by the Lipton Institute of Tea, the consumption of black tea helps in the improvement of the blood vessel reactivity and hence reduces the blood pressure and arterial stiffness, which indicates a notably better cardiovascular health profile.
A group of 19 healthy men (average age 33) was used by the researchers. The participants were asked to have one of five intakes of the tea over five periods lasting one week each.
The level of caffeine in each dose was standardised but the dose of flavonoid in tea was controlled at the levels of 0, 100, 200, 400 and 800 mg per day.
Generally, a standard cup of black tea contains about 100-200 mg of flavonoids, which again depends on the individual preference of making the tea.
During the entire period of the research, participants avoided naturally flavonoid-rich food and drinks like red wines and chocolates for ensuring that the results become a true reflection of flavonoid-rich black tea consumption only.
