Green Tea May Slow the Development of Diabetes

A recent study on mice conducted by the Medical College of Georgia in Augusta indicated that green tea could slow or prevent the onset of type 1 diabetes. The tea contains antioxidants that are key in preventing cell death and inflammation.


In the current study, researchers tested green tea’s main antioxidant, known as EGCG, in lab mice with type 1 diabetes. EGCG “dramatically slowed the development of type 1 diabetes.” After 4 months, 25% of the mice given EGCG developed diabetes, whereas 67% of the mice given water developed diabetes. After 5 and one half months, 45% of the EGCG group developed diabetes, while 78% of the group who took only water developed the disease.

Dr. Stephen Hsu commented on the study, “Our study focused on Sjogren's syndrome, so learning that EGCG also can prevent and delay insulin-dependent type 1 diabetes was a big surprise.” U.S. consumers spent $139 million on green tea supplements in 2007, a 3.4% decrease from 2006.
