Epigenetic changes are chemical modifications that turn our genes off or on. In a new study from Uppsala University, researchers show that tea consumption in women leads to epigenetic changes in genes that are known to interact with cancer and estrogen metabolism. The results are published in the journal Human Molecular Genetics.
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. “Previous studies have shown that tea […]
Unfortunately, the full article says they don’t know whether these changes are good or bad. In the computer world we say “garbage in, garbage out.” Also true of our bodies. Lack of nutrients or presence of toxins (anything that is not a nutrient) significantly affect our well-being.
Then why is it Asian women, who drink massive amounts of tea, have traditionally lived longer and had lower rates of diseases such as cancer? Is it how the tea is processed or the tea itself? Tea also comes in many, many varieties. Need more info here!
