Black tea may have therapeutic properties which could help control Type 2 diabetes, say scientists at the University of Dundee.
The team discovered that several black tea constituents, known as theaflavins and thearubigins, mimicked insulin action on proteins known as FOXOs.
Study leader Dr Graham Rena said: “FOXOs have previously been shown to underlie associations between diet and health in a wide variety of organisms. If we can identify substances that restore FOXO regulation in people with Type 2 diabetes, we might be able to use these to reduce the considerable burden of serious health problems associated with this diagnosis.”
Diabetes UK's view
Dr Iain Frame, Director of Research at Diabetes UK, added: “These are interesting results but, as the scientists themselves say, more research is needed before any potential benefits of black tea are proven.
“We wouldn’t recommend people with Type 2 diabetes increase their black tea intake as a way of treating their condition. However, eating a healthy balanced diet and taking regular physical activity can help people with diabetes control their condition.”
