Weight Loss, Cancer-Fighting and Anti-Bacterial: More on Green Tea!

Tea is probably the healthiest beverage on the planet. All tea has terrific stuff in it- but one particular compound in green tea- known as EGCG (short for epigallocatechingallate) keeps getting the lion's share of attention. Three new back to back studies show why.

In one study, EGCG given to mice significantly reduced the growth of breast cancer tumor cells. One group of mice was fed water mixed with EGCG for five weeks, while another group got only the water. Then all the mice were injected with breast cancer cells. The EGCG sipping mice had significantly less tumor growth. The researchers, from the University of Mississippi Medical Center, theorize that EGCG directly targets both tumor cells of breast cancer and their blood vessels, suppressing new blood vessel formulation in breast tumors and working against the proliferation of breast cancer cells.

In a second study, Egyptian researchers found that green tea can boost the potential of antibiotics to battle superbugs and other bacterial strains and even make previously antibiotic-resistant bacteria susceptible to treatment. "In every case, green tea enhanced the bacteria-killing activity of the antibiotics", said Dr. Mervat Kassem, lead researcher on the study.

Finally, in another animal study, mice with the "obesity gene" gained less weight and less fat when they ate chow laced with ECGC. They also had less sign of "fatty liver disease" and also lowered their triglyceride levels!

Cancer fighting? Weight reducing? Metabolic enhancing? Pretty impressive resume, wouldn't you say?

The weight control study fits nicely with a lot of other research showing the metabolic benefits of green tea. Some reports say that five cups a day is the magic number to help keep excess weight at bay. If you can't drink the real stuff on a regular basis, consider the supplement. High grade EGCG is a terrific addition to any weight loss regime, especially when combined with a low-sugar, high fiber, moderate calorie diet.

The ECGC in supplement form that I recommend is here. It contains 250 mg of green tea extract standardized to 50% EGCG. Standard dose is one to two capsules a day.
