Green tea may reverse memory impairment

Green tea may reverse memory impairment, according to the latest research from Northwest A&F University, in Yangling, China.

There’s nothing like a hot cup of green tea to get you through a long stressful day. It has a way of providing energy, soothing the soul, and refreshing your spirits.

Green tea has been used for millenniums in Asia as a potent tonic for its health benefits.

It is made from leaves that are unfermented, which gives it higher polyphenol antioxidant content than most teas.

Tea’s rich history as a medicine has made way for a new wave of green tea’s popularity as a beverage.

Now, history is starting to repeat itself, as green tea is gaining steam in the world of medical research and health experts are starting to recommend it as part of a healthy diet.

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.”

Science Daily reported on the study methods:

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.

The study showing that green tea may reverse memory impairment was published in The FASEB Journal, the official journal of the Federation of American Societies for Experimental Biology.
