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 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.
