No evidence support the consumption of GT/GTE could reduce the levels of HbA1c , HOMA-IR , fasting insulin , or fasting glucose in people with pre-diabetes/T2DM .
Green tea or green tea extract ( GT/GTE ) has been demonstrated to reduce insulin resistance and improve glycemic control .
However , evidence for this health beneficial effect is inconsistent .
This systematic review evaluated the effect of GT/GTE on insulin resistance and glycemic control in people with pre-diabetes/type 2 diabetes mellitus ( T2DM ) .
Does supplementation with green tea extract improve acne in post-adolescent women? A randomized, double-blind, and placebo-controlled clinical trial.
BACKGROUND Green tea is believed to have beneficial effects in the prevention and treatment of acne . OBJECTIVE To examine the effects of a decaffeinated green tea extract ( GTE ) , providing a daily dose of 856 mg of epigallocatechin gallate ( EGCG ) upon women with post-adolescent acne . METHODS A r and omized , double-blind , placebo-controlled clinical trial was conducted from May 2012 through October 2013 . A final group of 80 subjects were r and omly assigned to receive either 1500 mg of decaffeinated GTE or placebo ( cellulose ) daily for 4 weeks . Inflammatory lesion counts were used as the major outcome measurement . At baseline and after 4 weeks of treatment , anthropometric measurements , fasting glucose levels and a lipid profile were measured from both groups . RESULTS Sixty-four of 80 women , from 25 to 45 years of age with moderate-to-severe acne completed the study . Statistically significant differences were noted in inflammatory lesion counts distributed on the nose , periorally and on the chin between the two groups . However , there were no significant differences between groups for total lesion counts . Within-group comparison revealed that the GTE group had significant reductions in inflammatory lesions distributed on the forehead and cheek , and significant reductions in total lesion counts . GTE result ed in significant reductions in total cholesterol levels within the GTE group . CONCLUSIONS GTE result ed in significant reductions in lesions located on the nose , perioral area and chin . More research is required to determine whether a decaffeinated GTE st and ardized for EGCG content will provide clinical benefits in women with post-adolescent acne
