Tea is one of the most cherished health beneficial beverages you’ll find. The Chinese have been using it for its powerful medicinal benefits for centuries. Nadine Taylor stated in her book that they’ve been using it for as many as 4000 years.
Nowadays, research conducted in throughout the world is providing strong evidence to prove the health benefits associated with green tea. In 1994 a report published by the National Cancer Institute indicated that the consumption of green tea reduces esophageal cancer by up to 60%. Another study from the University of Purdue concluded a compound of green tea actually inhibits the growth and production of cancerous cells. On top of this, regularly drinking green tea will actually lower your cholesterol.
In summary I’ve outlined a bullet pointed list of conditions that green tea is reputed to improve or resist.
High cholesterol levels
Impaired immune function
So, what exactly is it that makes green tea so fantastic?
Green teas secret are the catechin polyphenols contained within. In particular epigallocatechin gallate which is an extremely powerful antioxidant. It inhibits the growth of cancer and kills cancerous cells. It is also effective at lowering cholesterol levels and resisting the formation of dangerous blood clots.
Researchers were puzzled for years as to the reasons the French consume a rich fat diet but have a lower rate of heart disease than Americans. In the late nineties the answer was discovered. Red wine contains resveratrol, it limits actually limits the effect of a fatty diet and smoking. A study conducted in 1997 at the University of Kansas found EGCG is up to two times as potent as resveratrol. This explains the reason heart problems are so rare in men from Japan.
So why don’t the rest of the tea family have the same healthy properties? They all come from the same plant. The key here is the production process. Green tea is steamed which keeps the EGCG compound within the leaf and prevents oxidization. Black and oolong tea is created from fermented leaves. These are low in EGCG as its converted into weaker, less beneficial compounds.
Further evidence that green tea assists dieters is gradually emerging. During November 1999 an American journal revealed the results of a recent study from the University of Geneva. They discovered that men who consumed green tea actually burned more calories per day than those who were given caffeine alone.
Green tea has dental benefits too. It has anti bacterial properties and can help prevent the onset of food poisoning. Skin creams and preparations containing green tea are also beginning to appear on the shelves of beauty outlets and drug stores.
Are There Harmful Effects?
The only documented side effect attached to the regular consumption of green tea is insomnia brought on by the caffeine content. However, it contains less than the average cup of coffee, around 30 to 60 mg of caffeine when compared to a cup of coffee with over a hundred mg’s.
