GREEN TEA

Green Tea-cancer

Green tea, most popularly known as the ‘anti-aging beverage’ is packed with nutrients. Cultures such as Japan, where aging is relatively slow and less-impairing have green tea as an essential part of their diet.

So what exactly is green tea?

Green, black and oolong teas come from the same plant, Camellia sinensis. The difference is that green tea has leaves that have not been fermented, so they contain the highest level of antioxidants. Some of the antioxidants and healing compounds found in green tea include polyphenols, catechins and various other types of flavonoids.

Even though it contains small amounts of caffeine, green tea consumption has been associated with more health benefits than even many ‘superfoods’.

GREEN TEA AND CANCER

In 1994 the Journal of the National Cancer Institute published the results of an epidemiological study indicating that drinking green tea reduced the risk of esophageal cancer in Chinese men and women by nearly sixty percent. University of Purdue researchers also concluded that a compound in green tea inhibits the growth of cancer cells.

Green tea helps to inhibit the onset of cancer by blocking the action of nitrosamines, which can cause cancer. Another way it may help fight cancer is through preventing cell mutation. The antioxidative actions of the polyphenols in green tea inhibit mutation of the DNA in healthy cells, which can cause them to become cancerous.

Research conducted by the Mayo Clinic shows that green tea helps kill cells of the most common form of leukemia. Scientists suggest that component of green tea – EGCG – helps kill the cancer cells by cutting off the communication signals they need to survive.

Stomach cancer is at its lowest rate in Shizuoka prefecture along the coast southwest of Tokyo. One explanation is that Shizuoka is a tea–growing district and its inhabitants drink large amounts of green tea.

A study was conducted in China during 1999–2000 on Ovarian Cancer and green tea consumption. The findings showed that ovarian cancer risk declined with increasing frequency and duration of tea consumption. The conclusion was that increasing frequency and duration of tea drinking, especially green tea, can reduce the risk of ovarian cancer.
