Green Tea and Cancer

The effects of green tea on cancer have been widely studied.

Green tea has anti cancer and anti mutagenic properties. It can protect against and reduce the risk of cancer. This is mainly due to the polyphenols contained in green tea. Polyphenols are powerful antioxidant phytochemicals. Catechins make up about 90% of polyphenols. Epigallocatechin-3-gallate (EGCG), the main constituent of catechins, has the potential to prevent and cure cancer.

How does green tea fight against cancer?

Polyphenols in green tea:

1. minimise cellular damage caused by free radicals.

2. enhance immune system, thereby, reducing the risks of certain cancers.

3. prevents cancer by stimulating apoptosis (eliminating old, unhealthy and unnecessary cells) and encouraging cell growth arrest (cells stop dividing).

4. regulates and promotes DNA repair.

5. induce cytotoxic T cells (immune cells) to destroy cancer cells.

Studies have shown that green tea polyphenols can potentially prevent breast, prostate, lung and skin cancer.
