Green Tea

Strong evidence

Active compounds

EGCG (épigallocatéchine-3-gallate)PolyphénolsCatéchines

Targeted cancers

breastprostatelungcolon

Anti-cancer actions

  • ✦Blocks tissue invasion by cancer cells
  • ✦Inhibits angiogenesis (formation of new blood vessels feeding tumors)
  • ✦Sensitizes cancer cells to radiotherapy
  • ✦Combined action with soy against estrogen-positive breast cancer

How to prepare it

Prefer unfermented Japanese green tea (sencha, gyokuro, matcha). EGCG is destroyed during the fermentation of black tea.

Recommended dosage

3 to 5 cups per day. Steep for 8 to 10 minutes to release the catechins.
