Green tea is the second most consumed beverage in the world after water, and is grown in at least 30 countries, according to Xuebo Liu, Ph.D., who authored a study on green tea at the Northwest A&F University of Yangling, China. The study demonstrated that a compound in green tea called epigallocatechingallate (EGCG) lowers the development of insulin resistance, obesity, and memory impairments in mice.Green tea is also known to boost immunity, keep the heart healthy, lowercholesterol levels and reduce the risks of cancer.
EGCG: The PowerUnderlying Green Tea
The driving force in green tea is a polyphenol called epigallocatechin-3-gallate (EGCG). Polyphenols are antioxidant-rich micronutrients that are found in green tea and in plant-based sources such as blueberries, chocolate, red wine and olive oil. Antioxidants protect healthy cells from oxidative damage and the EGCG found in green tea lowers the risk of contracting hypercholesterolemia, cardiovascular disease and cancers. Antioxidants do not extend the lifespan and can actually have a damaging effect on high-risk cancer patients such as smokers, but EGCG can be a great health game changerin the healthy population.
Study on Green Tea
Superfoods and other health foods like manuka honey brands have been extensively studied, and green tea is no different. A study on the benefits of green tea was conducted by Xuebo Liu, Ph.D and his team at the Northwest A&F University of Yangling, China and published in The FASEB Journal.
A research team from the College of Food Science and Engineering, Northwest A&F University, in Yangling, China, examined the impact of green tea on mice. The control group was fed a standard diet, a second group was administered a high-fat, high-fructose diet, and the third group was given green tea and a high-fatdiet. The mice were placed on the diet for 16 weeks.
The mice that were fed a high-fat and high-fructose diet gained body weight at the end of the study, compared to the control group. The body weight of the group that received green tea was far lower than expected and almost on par with the control group, as the green tea reduced obesity resulting from a high-fat, high-fructose diet.The mice that consumed green tea also did better on maze tests as the ECGC in the green tea enhanced their cognitive performance and negated memory impairment. The experiment proved that green tea protects the brain and enhances cognitive functions, reducing the brain insulin resistance caused by a high-fructose, high-fat diet.A rich body of research in the past had indicated the potential of EGCG to treat a variety of diseases, but the impact of EGCG on insulin resistance and cognitive remained unclear until the current study.
As we age, we experience little memory hiccups and packsome extra pounds. So green tea may be worth a try and an ideal substitute for the daily dose of caffeine.
