Green Tea Ingredient May Ameliorate Memory Impairment, Brain Insulin Resistance, And Obesity

The FASEB Journal has published a study on its online portal that has drawn the attention of many. This piece of research indicates several possible health benefits of green tea. Green tea was originally consumed in China and India from 4000 years ago and numbers of people around the world switching to Green tea due to its health benefits. It has become world’s most consumed liquid after water. There are many studies that suggest the health benefits of green tea.

A study involving the mice on green tea and its impact suggest that the EGCG (epigallocatechin-3-gallate), which is present in green tea and considered as the most biologically active component and abundant catechin, has the ability to alleviate high-fat and high-fructose (HFFD)-induced insulin resistance and cognitive impairment.

Though the number of studies and research has been conducted in the past on green tea and it’s health benefits which included the significant role of EGCG in treating the number of diseases in humans. But no one was certain about the Impact of EGCG in insulin resistance and cognitive deficits triggered in the brain un till now.

A Ph.D. research from the College of Food Science and Engineering, Northwest A&F University, in Yangling, China, Xuebo Liu along with other experts carried out this research. For this, they divided 3-month-old male C57BL/6J mice into three groups based on a diet which was

  •  Group of mice fed with standard diet
  • Another one with HFFD Diet
  • The last one with the HFFD diet and 2 grams of EGCG per liter of drinking water.

The study went for the 16 weeks in which research monitored the mouse regularly. They observed that the second group of mice which were given HFFD diet had higher body weight than the first group of mice with a controlled diet. The third group of mice showed some really good results, it was observed that the mice of the first group had higher final body weight than the mice of the group with diet HFFD+EGCG mice.

Other than this the Morris water maze test was done. In this test, it was observed that the mice of 2nd group ( HFFD Diet) took more time to find the platform as compared to the mice of the first group ( standard diet). The mice of the 3rd group (HFFD+EGCG  Diet) had lower escape latency and escape distance than the HFFD group on each test day.

Further, when the hidden platform was removed in order to start a probe trial. The research found that the mice of HFFD+EGCG group showed a good increase in the time spent in the target quadrant. Other than this they had greater numbers of platform crossings, while the HFFD-treated mice spent less time in the target quadrant when compared with control mice, with fewer platform crossings.

After this observation is was clear that the EGCG could improve HFFD-induced memory impairment. So, even the studies are indicating the health benefits of green tea. Here you have another reason to go for the cup of green tea instead of other.
