High blood pressure, which the World Health Organization describes as a “silent killer”
because most people with high blood pressure do not show symptoms at all
increases its risk for people who do not know they have the disease
and the consequences of neglecting it reach stroke, heart failure and kidneys.
It is a risk factor for heart disease!
and certain nutrients have been shown to be particularly capable of reducing the risk of developing it.
Research has identified specific ingredients that can help stave off the risk of it.
Oolong tea – a traditional Chinese tea made from the leaves of the Camellia sinensis plant – falls into this category.
A study published in the journal JAMA Network examined the long-term effects of drinking oolong tea on the risk of it.
The study was carefully designed and used a large number of subjects (1,507 subjects, including 711 men and 796 women).
The researchers collected detailed information on tea consumption and other lifestyle and dietary factors associated with HBP risk.
The result showed that those who drank at least 120 ml/day (half a cup) of oolong tea for a year had a 46% lower risk of developing it compared to non-tea drinkers.
Moreover, among those who drink 120 to 599 ml/day (two and a half cups), the risk of developing reduced by 65%.
The researchers concluded that regular oolong tea consumption of at least 120 ml/day for one year
“significantly reduces the risk of developing it in the Chinese”.
“Caffeine can raise blood pressure by up to 10 mm Hg in people who rarely consume it,” the Mayo Clinic explains.
“But people who drink coffee regularly may have little or no effect on their blood pressure.”
According to the NHS, “To see if caffeine raises your blood pressure
check your blood pressure within 30 minutes of consuming a caffeinated beverage.
If your blood pressure increases by 5 to 10 mm Hg
you may be sensitive to the BP-raising effects of caffeine”.
