Does Green Tea Improve Glucose Tolerance?

Green Tea and glucose tolerance?

The results of a recent study suggest that supplementation with 3 capsules of green tea extract (total: 890 +/- 13 mg polyphenols and 366 +/- 5 mg EGCG) increased fat oxidation, insulin sensitivity, and glucose tolerance in young healthy men.

“BACKGROUND: Green tea consumption is reportedly associated with various health-promoting properties. For example, it has been shown to promote fat oxidation in humans at rest and to prevent obesity and improve insulin sensitivity in mice.”

“CONCLUSIONS: Acute GTE ingestion can increase fat oxidation during moderate-intensity exercise and can improve insulin sensitivity and glucose tolerance in healthy young men.”
