Green Tea has had more zealous acceptance than nearly any other food product in the past twenty years. There are claims that substances contained in green tea inhibit cancer cells, improve cholesterol, reduce the appetite and strengthen the immune system. Not since the Vitamin C rage has another food product been treated as a must have. The following summarizes the more important claims; some backed by research, some not.

Research at the University of Purdue, concluded that a compound in green tea inhibits the growth of cancer cells. A report published in a 1994 Journal of the National Cancer Institute indicated that drinking green tea lowered the risk of esophageal cancer.

There are also studies that have concluded green tea lowers overall cholesterol levels and improves the ratio of good (HDL) cholesterol to bad (LDL) cholesterol. Still other studies indicate that green tea is also reputed to be helpful with Cardiovascular disease, infection, impaired immune function, Rheumatoid arthritis.

Green Tea is rich in antioxidants, particularly catechin polyphenols. This powerful antioxidant has been shown by researchers at the University of Kansas to be twice as powerful as resveratrol, the compound that gives red wine its amazing heart protecting effects. To further support the claim, Japanese men have a low heart attack rate despite the fact that more than 70% smoke cigarettes.

The results of a study published by American Journal of Clinical Nutrition showed a green tea extract, when taken with caffeine can lead to an increased rate of calorie burning. Green Tea has bacteria fighting abilities that can helps in prevention of tooth decay and food poisoning.

There does not seem be a real consensus on how much green tea should be consumed. Some recommend as many as 10 (six to eight ounce) cups per day, while others suggest at least three cups.

There are few negatives effects caused by drinking green tea other than those caused by the caffeine that is present. A cup of green tea contains about 60% of the caffeine found in a cup of coffee. For those people who are sensitive to caffeine, green tea may cause insomnia or nervous irritability.

If you are unable to drink green tea during the day, a green tea extract will provide similar benefits. These can be found in most supermarkets.

Clearly, the research suggests there are significant health benefits to adding green tea as a component of your daily diet. If your fighting to lose weight and gain better health, a warm cup of green tea will hit the spot.

Do not use green tea without first talking to your doctor if you have heart problems or high blood pressure, kidney disease, an overactive thyroid (hyperthyroidism), an anxiety or nervous disorder, or a bleeding or blood clotting disorder or if you take a blood thinner such as warfarin (Coumadin).
