Put the Tea Kettle on to Lower Your Glaucoma Risk
Drinking at least one cup of hot caffeinated tea per day could lower your risk for glaucoma by as much as 74 percent, suggests a study published in the British Journal of Ophthalmology. Glaucoma encompasses a group of eye diseases that can cause vision loss and blindness.
Researchers at the David Geffen School of Medicine at the University of California, Los Angeles, reviewed data from the 2005-2006 National Health and Nutrition Examination Survey, which included information on coffee, tea, and soft drink consumption, as well as eye test results, for 1,600 men and women. About 5 percent of survey participants had glaucoma.
According to researchers, of all of the beverages, only caffeinated hot tea was linked to a lower risk of glaucoma. Other beverages, including hot coffee (caffeinated or decaf), caffeinated iced tea, and soft drinks did not decrease glaucoma risk. The reasons for this are not well understood, but it could be that plant compounds in tea – phytochemicals and flavonoids – have anti-inflammatory and antioxidant properties that protect against glaucoma.
