Tea Can Change Gene Expression in Women
Research shows that gene expression—characteristics or effects attributed to a particular gene—can be influenced by external factors, including lifestyle and the environment. Now, a Swedish study published in Human Molecular Genetics shows that drinking tea can affect gene expression in women.
These so-called epigenic changes are associated with cancer and estrogen metabolism, but whether they protect against disease or promote it is not yet known. The goal of the recent study was to determine whether coffee and tea cause gene changes.
Researchers analyzed data from 3,096 adults, looking at coffee and tea consumption and testing blood samples for indications of epigenic changes. Study results revealed coffee consumption caused no such changes in men or women, while drinking tea was linked to epigenic changes in women, but not in men.
