Green tea may offer blood pressure and cholesterol benefits

Green tea may offer blood pressure and cholesterol benefits, according to a new study published in the scientific journal, Nutrition, Metabolism and Cardiovascular Diseases. The meta-study of 20 randomized clinical trials found that consuming green tea may help manage blood pressure and lower cholesterol levels.

The authors of the study examined data from more than 1500 study participants and found that green tea consumption generates significant reductions on systolic blood pressure, total cholesterol and LDL cholesterol. LDL is referred to as “bad” cholesterol because high levels of LDL is associated with higher risk of a heart attack. Consumption of 5-6 cups of green tea daily was the consumption level associated with lower blood pressure and cholesterol, according to the authors.

More research on green tea called for

The authors called for more research on green tea benefits and cautioned that green tea should not be considered a substitute for current medical management (medication and other therapies) of people with high blood pressure and high cholesterol.

The conclusion from the abstract for the published study (subscription or purchase required to view full text) states:

Green tea intake results in significant reductions in systolic blood pressure, total cholesterol, and LDL cholesterol. The effect size on systolic blood pressure is small, but the effects on total and LDL cholesterol appear moderate. Longer-term independent clinical trials evaluating the effects of green tea are warranted.

 Green tea contains between 30 and 40 percent water-extractable polyphenols, which may also be consumed in concentrated form in products like Sunphenon. Polyphenols from green tea have been shown to have numerous biochemical and physiological benefits, including antioxidant, antimicrobial, deodorant and thermogenic (fat burning) activities.
