Could something as simple as a cup of green tea help protect your DNA?
In one small human trial, researchers found that within an hour of drinking around 200 millilitres of green tea, markers of DNA damage in people's cells fell by approximately 30%, while the activity of a DNA repair enzyme increased.
And there's more.
Large observational studies have linked drinking around three cups of tea a day with a lower risk of premature death, although that doesn't prove tea is responsible.
A major review of 96 meta-analyses also found associations between tea consumption and several health benefits, often around two to three cups a day.
And one final tip. Don't pour boiling water straight onto green tea leaves.
Let it cool slightly first to avoid that bitter taste.
