It is well known that our environment and lifestyle factors, such as food choices, smoking and exposure to chemicals, can lead to epigenetic changes. In the current study, researchers from Uppsala University in collaboration with research groups around Europe, investigated if coffee and tea consumption may lead to epigenetic changes. Previous studies have suggested that both coffee and tea play an important role in modulating disease-risk in humans by suppressing tumour progression, decreasing inflammation and influencing estrogen metabolism, mechanisms that may be mediated by epigenetic changes.
The results show that there are epigenetic changes in women consuming tea, but not in men. Interestingly, many of these epigenetic changes were found in genes involved in cancer and estrogen metabolism.
