Can Green Tea help lower the risk of type 2 diabetes?

Some controlled trials show that green tea can cause mild reductions in blood sugar
levels. It may also lower the risk of developing type 2 diabetes.
This meta-analysis suggested that green tea had favorable effects, ie, decreased fasting
glucose and Hb A1c concentrations. Subgroup analyses showed a significant reduction in
fasting insulin concentrations in trials with high Jadad scores.
