Why Green Tea is Good for You
Should you hop on the green tea band wagon? Current research seems to answer with a resounding "yes." See why you may want to adopt this healthy habit.
Research out of Columbia University Medical Center shows that an oral green tea extract, Polyphenon E, seems to inhibit vascular endothelial growth factor and hepatocyte growth factor, both of which promote tumor cell growth, migration and invasion. Currently, researchers are conducting several ongoing studies to explore the use of oral green tea extract in high-risk women for the primary prevention of breast cancer.
According to a recent study led by Penn State food scientists, mice fed an antioxidant found in green tea called epigallocatechin-3-gallate, or EGCG, and corn starch had a significant reduction in their blood sugar levels compared to mice that were not fed the compound. For humans, this may mean that green tea could help control blood sugar increases (especially in people with diabetes) that are brought on when eating starchy, high carb foods.
Good news for female green tea drinkers: recent research shows women who drink green tea may lower their risk of developing some digestive system cancers, especially cancers of the stomach/esophagus and colorectum. According to a study led by researchers from Vanderbilt-Ingram Cancer Center, regular green tea consumption, defined as tea consumption at least three times a week for more
The study, led by researchers from Third Military Medical University in Chongqing, China, found that mice treated with EGCG (a key property of green tea), required less time to find a hidden platform. Overall, the results revealed that EGCG enhances learning and memory by improving object recognition and spatial memory.
This new development could be used to help combat degenerative diseases and memory loss.
Research shows that green tea lowers total cholesterol and raises HDL ("good") cholesterol in both animals and people. One population-based clinical study found that men who drink green tea are more likely to have lower total cholesterol than those who do not drink green tea.

In one large-scale clinical study researchers compared green tea drinkers with non-drinkers and found that those who drank the most tea were less likely to develop pancreatic cancer. This was particularly true for women. However, it is not clear from this population-based study whether green tea is solely responsible for lowering pancreatic cancer risk, or if other factors were responsible.
