Most people run to get their first cup of coffee in the AM to start the day. Maybe you are one of them. There is ample data that a few cups of black coffee may have health benefits. How about after the cup of Joe" Green tea has support as a healthy choice, albeit not as popular as coffee. In "preclinical" studies, green tea extract (GTE) improves gut barrier function and reduces intestinal and systemic inflammation. Whether green tea or a GTE can do the same in humans to improve gut health and subsequent blood sugar control was studied in humans in a randomized trial.
Research Study Methods
A randomized, double-blind, placebo-controlled study in adults with metabolic syndrome (MetS predicting future diabetes and heart diseases) and matched healthy persons who received a placebo or 1 g/d GTE for 28 days. Fasting blood glucose, insulin, and lipids were assessed at d 0, 14, and 28 days of each intervention. Intestinal inflammation was assessed in stool samples.
Study Results
Overall, 21 subjects with MetS (average age 40) and 19 healthy persons (average age 32) completed the study. Participants’ total polyphenol intakes decreased during each intervention compared with baseline (P < 0.001). Myeloperoxidase, a marker of inflammation, was lower in the GTE group. Fasting insulin, triglycerides, and total and high-density lipoprotein (HDL) cholesterol were unaffected by treatment, However, fasting blood glucose decreased in response to GTE.
Researchers' Conclusions and What You Can Do with Green Tea
Dietary interventions with green tea extract in healthy and MetS adults decreased fasting glucose and intestinal inflammation (myeloperoxidase) which was associated with improvements in fasting insulin.
Drinking several cups of green tea daily (after you finish your coffee) may improve glucose control with reductions in intestinal inflammation contributing to enhancing insulin sensitivity. Maybe that is why, in part, they live so long and healthy in Okinawa (a famous Blue Zone area of longevity)
About the author: At his core, Dr. Joel Kahn believes that plant-based nutrition is the most powerful source of preventative medicine on the planet. Having practiced traditional cardiology since 1983, it was only after his own commitment to a plant-based vegan diet that he truly began to delve into the realm of non-traditional diagnostic tools, prevention tactics, and nutrition-based recovery protocols.
