A new study has found that drinking black tea appears to reduce
several risk factors for heart disease, potentially lowering your risk
of heart attack and stroke.
In the study, published in the journal Preventive Medicine, drinking
three cups of tea for 12 weeks (with no milk or sugar) led to highly
significant reduction in blood sugar levels and triglycerides, which are
unhealthy fats. Triglyceride levels fell by a whopping 39 percent in
males and 29 percent in females.
In addition, drinking tea led to an increase in levels of HDL
cholesterol, long considered to be the ‘good’ type of cholesterol –
though recent research from Harvard Medical School has called into
question .
It also increased blood levels of antioxidants, which can protect
blood vessels and tissue against oxidative stress and inflammation.
Black and green teas are loaded with polyphenols, antioxidants that are
associated with a wide range of health benefits.
A past study also found that drinking tea can significantly reduce
C-reactive protein (CRP) levels in moderate and high risk people. CRP is
considered a marker for inflammation and cardiovascular disease.
According to the American Heart Association, having low CRP is
associated with a low risk of developing cardiovascular disease, but the
research is mixed on whether lowering CRP actually reduces
cardiovascular risk.
In the CRP study, tea drinking also lowered uric acid, which has been
associated with increased cardiovascular risk. Uric acid may promote
low density lipoprotein oxidation and produce damaging free radicals.
The researchers recommend sipping tea without milk or sugar. Milk may reduce some of the availability of the polyphenols.
