That great English tradition, tea drinking, has been shown to cause epigenetic changes in women who partake. Writing in the journal Human Molecular Genetics a team from Uppsala University, Sweden, has demonstrated that consumption of tea triggers changes in genes that are known to interact with cancer and estrogen metabolism. Earlier research has hinted at a connection between drinking both tea and coffee and the modulation of disease risk in humans. The mechanism was purportedly through suppression of tumor progression, reducing inflammation and influencing estrogen metabolism. All such mechanisms might themselves be mediated by epigenetic changes. The team is yet to demonstrate whether tea drinking is beneficial, they have simply shown that there is a putative mode of action in epigenetics.
