Good advice: Keep the flu away with green tea

Preventing influenza with green tea? Yes, says the research.

Good advice: Keep the flu away with green tea.


Here is some good advice for those of you who want to keep the flu away this season; starting drinking green tea. It has been proven, in a high class study (a randomized controlled trial) conducted in Japan that drinking green tea can help prevent catching the flu.

200 health workers took part in the research study, and they were blinded towards what kind of pills they got, meaning they did not know if they got the placebo or the actual green extract capsule.


The Japanese study had a control group, who were given placebo pills (pills with no effect, just sugar pills) and compared these with a group who received capsules with green tea extract. These green tea extracts contained 378mg/day catechins and 210mg/day theanine. Catechins is the most active antioxidant in green tea, and has shown in several studies to have beneficial effects upon our health situation.


After five months, there was a statistically significant difference between the control group and the green tea extract group. Concluding that there was in fact a significantly lowered prevalence of flu episodes amongst the healthworkers who had been given the green tea extract capsules.


There, it has been proven in a blinded, randomized controlled trial featuring 200 participants; drinking green tea will help you keep that nasty influenza infection away. So, go put on the kettle and enjoy a freshly brewed cup with your family and friends right now. You have thoroughly deserved it. And you know what the new saying goes like, right?


"A cup (or three) of green tea a day, keeps the influenza virus away!"

Just for information; a similar study was done (although of a type of study, observational, which is weaker in the research hierarchy) amongst schoolchildren. It concluded that there was less influenza virus infections amongst the children that drank green tea daily. Although, it did not find a significant difference between drinking 1 or 5 cups a day. - Resolver

Since I have been on green tea, which is years I have not had cold or flu. I make mine up once a week with honey and put in fridge.

Sounds nice, Jackie! So, you prefer to drink it cold then? More icetea-ish?

What a great hub. Honestly, I had no idea that green tea could keep the flu away. So I guess I will buy a whole box. I had a nasty flu, the nastiest ever about two months ago, and it took a while to go away. Had I known about green tea I would have tried it, then. But then again, it's preventative, right, not curative? Which means I can't substitute it for Neocitran.
