MedicalResearch.com Interview with: Yuji Komorita, MD, PhD Department of Medicine and Clinical Science, Graduate School of Medical Sciences, Kyushu University Maidashi 3-1-1, Higashi-ku, Fukuoka MedicalResearch.com: What is the background for this study?   Response: Both green tea and coffee have been reported to confer health benefits, and reduce all-cause mortality in general population, respectively. However, no study has investigated the combined impact of them on health or mortality. We followed 4,923 Japanese patients with type 2 diabetes registered at the Fukuoka Diabetes Registry (median, 5.3 years; follow-up rate, 99.5%).  MedicalResearch.com: What are the main findings?  Response: Drinking 4 or more daily cups of green tea was associated with 40% lower risk of death, and 2 or more cups of coffee was associated with 41% lower risk. Furthermore, the combination of 4 or more cups of green tea and 2 or more cups of coffee every day was associated with 63% lower risk of death. We have shown that higher consumption of green tea and coffee was associated with reduced all-cause mortality, and their combined effect appeared to be additive in people with type 2 diabetes. (more…)
