Does green tea (Camellia sinensis, Theaceae) prevent cancer? There may be some evidence. Today I am sharing an infographic I made about green tea and its anti-inflammatory properties. This infographic is not comprehensive, so if you are interested in the topic I encourage you to check out this website which discusses more of the evidence. Some clinical studies have not demonstrated green tea’s efficacy at inhibiting cancer. This could be due to the different varieties of tea (black, green, white, etc.), regional differences in growth (higher level of secondary metabolites in soil-rich areas), or the population studied (genetic and environmental differences). Hope you enjoy my infographic and I encourage you to investigate the research further. For now, I’m going to continue enjoying my green tea and lemon each morning. Enjoy!
