Green Tea to Lower Cholesterol? Not So Fast

This was a study of 14 healthy individuals that consumed 6 grams of green tea, followed by a measure of flow-mediated dilation.  The results showed an increased flow-mediated dilation with tea (peak at 30 minutes post consumption).  There was no change to antioxidant status after consumption.  It's proposed that the improved flow-mediated dilation is how green tea reduces cardiovascular disease risk.

The Hype

I came across multiple articles with headlines screaming "Green Tea Protects Against Heart Disease" since this study was published in June.  I think there is significant research that still needs to be completed before it can be determined for sure how tea works to prevent heart disease.  A study of 14 individuals is a small study.

Drinking 6 grams of green tea, would equal about three - 6 ounce cups of green tea each day.  (Based on making 1 six ounce cup of tea with 1 teaspoon or 2.25 grams of green tea.)  However, the study results are based on consuming 6 grams of tea in one setting followed by improved flow-mediated dilation at peak levels 30 minutes after consumption.  How likely is it for you to drink three cups of tea quickly, back-to-back to reproduce the short-term benefit shown in this study?

To me, that is not a very effective way to reduce heart disease risk.  But, I will say that if you like green tea - drink it.  Many studies are showing that green tea is beneficial to heart disease.  The what, how, and how much is yet to be determined.  Who knows what future studies will find?!
