Drinking tea linked to epigenetic changes on cancer-associated genes–but only for women
Ruth Schuster| Haaretz | July 06, 2017

What is sure is that tea consumption changes the expression of genes associated with cancer and estrogen metabolism – in women.

Whether the change is good, bad or neutral remains to be seen.

Tea and coffee can affect health in similar ways, says the team from Uppsala University University in collaboration with scientists around Europe. But coffee had no such epigenetic effect, the researchers observe.

Both coffee and tea have been found to affect the risk of disease, for instance by suppressing tumor progression and decreasing inflammation, and also through influencing the estrogen metabolism.

The new study does not purport to say whether the epigenetic changes are beneficial, neutral or otherwise – meaning, whether drinking tea is healthy or not. Or doesn’t matter. It just says that drinking tea causes changes to certain genes in women, but not men.

The new research encompassed just over 3,000 Europeans and involved meta-analyses of the results. Ek also notes that more women were studied than men, making it harder to find significant associations for the male component.

Open questions abound. The researchers did not narrow their study to a specific type of tea, or even quantities of tea that would have epigenetic effect on women.

    less immunogenic variants may enhance the ability of a tumour to bypass
    the host’s immune system. This process is referred to as tumour
    immunoediting. Interesting point.
