Study finds large reduced diagnosis of serious eye condition in regular tea drinkers
Carrots are famous for helping us to see in the dark, thanks to their high vitamin A content, but a lesser known sight saver could be the humble British cup of tea.
Commenting on the study, Dr Catherine Hood at the Tea Advisory Panel (TAP), said: “A new study1 in 1678 adults, published in the British Journal of Ophthalmology, has found that enjoying at least one cup of tea daily was associated with a statistically significant 74% reduced risk of being diagnosed with glaucoma. This is an irreversible condition where a build-up of pressure in the eye can result in sight loss. No beneficial effects were seen when participants drank caffeinated and decaffeinated coffee, iced tea or soft drinks.
“Around two million people in the UK live with sight loss according to the RNIB2. A major cause is glaucoma which is thought to be responsible for one in ten people who register as blind3.
“This study found a significant reduction in risk when people drank tea regularly. A reason for this health benefit could be the link between tea and its high flavonoid content as these compounds are known to have many health antioxidant properties.”
“While the mechanisms involved in this study need to be explored further, it would appear that drinking at least one cup of tea daily could help to prevent conditions such as glaucoma which cause irreversible sight loss”.
