Help Boost your Immune System

Green Tea

Green tea is about 40% polyphenols by weight — and may be the most powerful of all the teas.

It contains compounds called catechins, as well the antioxidant quercetin and the amino acid L-theanine, all of which support a strong immune system. These compounds are effective agents in helping the body fight viruses, such as influenza and many forms of gastrointestinal infections.

Green tea is an immunity warrior. One study showed that women under 50 who drank green tea at least three times per day reduced their risk of breast cancer by 37%.

But you may not necessarily have to drink green tea all the time to reap its benefits. In fact, gargling these catechins has also been shown to reduce incidences of influenza among the elderly.
