The fat cells were grown in alab and fed tea extracts, insulin and radioactive sugar. The chemical epigallocatechin gallate (EGCG) most enhanced insulin. When green tea isoxidized into oolong and black tea, EGCG forms polyphenols, which are strong antioxidants. Black, green and oolong teas improved insulin activitythe most. Adding milk diminished the teas positive effect on the insulin.
