Scientific study: tea extends life and reduces heart disease and stroke
A new Chinese study indicated that drinking regular cups of tea can help you live longer.
And researchers from the Chinese Academy of Medical Sciences in Beijing revealed that drinking tea at least three times a week; It can extend life by more than a year.
'Tea consumption is usually associated with a lower risk of cardiovascular disease and all causes of death,' said researcher Dr. Chenian Wang. The favorable health effects are most powerful for green tea, and for long-term tea drinkers. ”
In the study, participants were divided into two groups: those who drank tea regularly, and those who drank less than three cups per week, prior to the seven-year evaluation.
The analysis revealed that regular tea drinkers were less likely to have heart disease and stroke, and lived an average of 1.26 years longer than those who rarely drank tea.
While the reason remains unclear, the researchers suggest that it may be due to the polyphenols in tea, chemicals with antioxidant properties.
The study also stated: 'Instrumental studies have suggested that the main bioactive compounds in tea, which are polyphenols, are not stored in the body in the long term.'
Thus, drinking tea repeatedly over a long period of time may be necessary for the cardiac effect.
They found which types of tea were the most effective, and found that green tea was more beneficial in reducing the risk of heart disease.
This may be due to the fact that green tea is richer in polyphenols than black tea, or because black tea is often served with milk, which may have a negative effect on heart function.
Meanwhile, the study also found that the tea's protective effects were more beneficial for men than women.
'One reason may be that 48% of men consumed their regular tea, compared to only 20% of women,' said Dr. Wang.
Second, the incidence and death rates of heart disease and stroke were much lower. These differences made it more likely that you would find statistically significant results among men.
The researchers now hope to conduct follow-up studies to understand the tea's protective effects.
Despite this, the dietitian at Aston University said: 'As with all studies conducted on groups like this one, there is no evidence of a causal relationship, only that drinking tea is linked to a longer life.'
