It looks like tea affects which segments of our genes are expressed – and which aren't. That may explain why tea is often associated with various healing properties. In particular, it looks like some of the gene segments that it affects may include ones associated with cancer risk and high blood pressure. No good news for coffee drinkers, though: the effect on those genes doesn't come with drinking coffee.
Now, at this stage it is an just an observational study, so we don't have conclusive evidence that drinking tea 'turns off' these gene segments to lower your risk of getting cancer or lowering your blood pressure, but it does look like a promising explanation! And, there's nothing poisonous about tea – so if you are affected by conditions that might be lindered by drinking tea, there's no harm in consuming a few select teas.

Hat Tee Auswirkungen auf unsere Gene?
Tee gilt schon lange als bewährtes Heilmittel. Eine schwedische Studie liefert nun eine mögliche Erklärung: Vor allem bei Frauen könnte das Heißgetränk die Gene beeinflussen.
At this point, it is a correlation. That's the first step in figuring out what to continue investigating 🙂
What kind of tea? Seems to me more like a correlation…
