teaspoonful, was chock-full of antioxidants, yielding about 250 milligrams of catechins, a third of which were EGCG. It also contained 86 milligrams of caffeine, slightly less than a regular cup of coffee. A single bag of the green tea sold by Lipton and Bigelow contained somewhat smaller amounts of antioxidants than Teavana’s green tea and generally minimal amounts of caffeine. But Teavana’s recommended serving size was large, and the tea was also far more expensive, resulting in a higher cost per serving. The report calculated that the cost to obtain 200 milligrams of EGCG ranged from 27 cents to 60 cents with the tea bags, and $2.18 with the Teavana loose tea leaves.

Green tea may help protect the brain during sleep apnea

The May 15, 2008 issue of the American Journal of Respiratory and Critical Care Medicine published the discovery of researchers at the University of Louisville in Kentucky that the antioxidant property of green tea could help prevent the cognitive deficits associated with obstructive sleep apnea (OSA). Sleep apnea occurs when breathing is periodically interrupted during sleep, temporarily depriving the brain of oxygen. When caused by airway collapse or blockage which obstructs breathing during sleep, the condition is known as obstructive sleep apnea.
