Doctors Health Press, a division of Lombardi Publishing Corporation and a publisher of various natural health newsletters, books, and reports, including the popular online Doctors Health Press e-Bulletin, is reporting on a new health breakthrough that has found that women who drink green tea may have a reduced risk of certain digestive system cancers—especially those in the stomach, esophagus, and colorectum.
As reported in Doctors Health Press e-Bulletin (http://www.doctorshealthpress.com/cancer-articles/extensive-study-shows-green-tea-may-help-prevent-cancer), in a recent study, researchers surveyed women in a large population study in Shanghai, which included 75,000 women over 45. In an initial interview, they were asked if they drank tea, what type of tea they consumed, and how much they consumed. Not surprisingly, most Chinese women preferred green tea.
As noted in the article “Extensive Study Shows Green Tea May Prevent Cancer,” the study reports that regular green tea consumption (drinking at least three times a week for more than six months) was linked to a 17% reduced risk of all digestive cancers combined. If the women drank two to three cups per day, the reduced risk grew to 21%. This trend was strongest for cancers of the stomach, esophageal, and colorectal areas. Colorectal cancer is among the most fatal of all types of cancer.
The Doctors Health Press e-Bulletin article notes that for women who had regularly consumed green tea for at least 20 years, the risk was reduced by 27%. For colorectal cancer, the figure was 29%. The study shows simply that the more the body is exposed to green tea, the greater the protection against cancer.
As the article explains, tea contains polyphenols, or natural chemicals that include catechins, like EGCG and ECG. Catechins have antioxidant properties that may inhibit cancer by reducing DNA damage, and blocking tumor cell growth and invasion.
According to Doctors Health Press e-Bulletin, the study did account for other lifestyle factors that could have had an effect, such as diet, exercise habits, and occupation. Notably, smokers and those who regularly drank alcohol were excluded. Any of these factors may have affected the results.
