Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

Benefits of green tea to control blood sugar

Diabetes-tool-box2-150x150Researchers in Chongqing, People’s Republic of China, evaluated the effect of green tea on glucose control and insulin sensitivity.

First, the details.

  • 17 studies with data from 1133 people were included in the meta-analysis.
  • Jadad scores were used to assess the quality of the studies-

And, the results.

  • Drinking green tea significantly reduced the fasting glucose and hemoglobin A1c (A1c) concentrations by -0.09 mmol/L and -0.30%, respectively.
    • Blood levels of A1c are used to measure average blood sugar levels over prolonged periods.
  • The best studies, based on high Jadad scores, showed that green tea significantly reduced fasting insulin concentrations (-1.16 ?IU/mL).

The bottom line?

The authors concluded, “This meta-analysis suggested that green tea had favorable effects, ie, decreased fasting glucose and A1c concentrations.”

Most important is the significant reduction in A1c achieved by green tea. Other reviews of CAM options have not been able to show this response consistently.
