Green Tea Reviews

What Is Green Tea?

Green tea is more of a type of tea preparation from the leaves of the Camellia Sinensis that has undergone oxidation in the steaming process. It has its origins from China that eventually found its ways in many Asian and Middle Eastern cultures. It is predominantly used in Japan after it was introduced there as about the same time as Zen Buddhism was introduced by a Japanese Buddhist monk schooled during the Song Dynasty in China.

Since then, there have been a number of plant varieties used for green tea preparation with Gyokura as the highest grade Japanese green tea.

Research made in Japan claims that taking 5 cups of green tea each day burns 70 to 80 calories. Dr. Nicholas Perricone, a self-anointed anti-aging specialist guessing in the “Oprah Winfrey show” claimed to have lost 10 lbs in 8 weeks drinking green tea.

How Does Green Tea Work For Weight Loss?

The main benefit of green tea lies on its abundant content of catechins polyphenols, especially epigallocatechin gallate (EGCG). This is a powerful anti-oxidant that is also known to lower LFL cholesterol levels.

Green Tea has been associated with the French Paradox where despite consuming fat-rich diets, the French have lower incidence of heart disease, live healthier and longer lives than Americans. It’s all because of red wine which contains a polyphenol Resveratrol that also reduces if not neutralize the ill-effects of smoking and a high fat diet. But a 1997 research study at the University of Kansas have unraveled that EGCG is twice more potent than Resveratrol.

But while there is little doubt about its beneficial heath benefits, claims about its weight-reducing properties have yet to be independently confirmed from human clinical trials.

Is Green Tea Safe?

For a long time, the only unwanted side effect from consuming green tea is insomnia which is more the result of caffeine in the tea preparation itself. But it contains a lot less caffeine, about 60mg in 8 ounces of tea than coffee which has over 100mg of caffeine in the same amount. It is generally a safe substance.

But in 2008, the US Pharmacopeia indicated that among green tea drinkers, there had been reported serious side effects that included 34 cases of liver damage out of the millions of green tea drinkers. But it remains inconclusive as these cases were categorized merely as possible or probably. The risk of such side effects was increased when the tea is taken on an empty stomach.
