GREEN TEA AND BACTERIA/VIRUSES

Bacteria and viruses are invisible to the naked eye, but they’re virtually everywhere. And although many of these small one-celled organisms are harmless, others can cause raging infections that can kill a person in a matter of days. Both bacteria and viruses can be transmitted in many ways – through unwashed hands, spoiled food, the exchange of bodily fluids, the touching of a contaminated surface, or a cough or a sneeze.

The immune system is supposed to destroy these pathogens or at least keep them under control. But sometimes it’s simply too overworked to do so, or is unable to get the job done even when operating at full steam.

Fortunately, green tea comes equipped with its very own antibacterial and antiviral capabilities, most likely to defend itself against invading insects, bacteria, fungi and viruses. And it can be powerful! Studies have shown that tea catechins can fight or even destroy the bacteria that cause cholera, pneumonia, abscesses, botulism, dysentery and food poisoning, as well as those that cause cavities and bad breath. As for viruses, the catechins can inhibit the action of the flu virus, herpes simplex, polio and HIV, among others.  

Just by drinking green tea you may be able to “borrow” some of the incredible disease-fighting prowess of the tea leaf. And it doesn’t take a gallon of tea to do this. One study found that the amount of catechins in just one cup of tea was 2-3 times greater than that needed to kill the bacteria that cause cholera.1 But you don't need to worry that green tea will disturb the "friendly" bacteria in your digestive tract. On the contrary, it promotes them!
