Green tea ingredient may ameliorate memory impairment, brain insulin resistance, and obesity
Green tea ingredient may ameliorate memory impairment, brain insulin resistance, and obesity:- “Green tea is the second most consumed beverage in the world after water, and is grown in at least 30 countries,” said Xuebo Liu, Ph.D., a researcher at the College of Food Science and Engineering, Northwest A&F University, in Yangling, China. “The ancient habit of drinking green tea may be a more acceptable alternative to medicine when it comes to combatting obesity, insulin resistance, and memory impairment.”
Liu and colleagues divided 3-month-old male C57BL/6J mice into three groups based on diet:
1) a control group fed with a standard diet,
2) a group fed with an HFFD diet, and 3) a group fed with an HFFD diet and 2 grams of EGCG per liter of drinking water.
For 16 weeks, researchers monitored the mice and found that those fed with HFFD had a higher final body weight than the control mice, and a significantly higher final body weight than the HFFD+EGCG mice. In performing a Morris water maze test, researchers found that mice in the HFFD group took longer to find the platform compared to mice in the control group. The HFFD+EGCG group had a significantly lower escape latency and escape distance than the HFFD group on each test day. When the hidden platform was removed to perform a probe trial, HFFD-treated mice spent less time in the target quadrant when compared with control mice, with fewer platform crossings. The HFFD+EGCG group exhibited a significant increase in the average time spent in the target quadrant and had greater numbers of platform crossings, showing that EGCG could improve HFFD-induced memory impairment.
“Many reports, anecdotal and to some extent research-based, are now greatly strengthened by this more penetrating study,” said Thoru Pederson, Ph.D., Editor-in-Chief of The FASEB Journal.
