Green Tea: Health and Antioxidant properties

October 13, 2012

Below we give you the latest on Green Tea research and how the scientists are demonstrating its health-promoting benefits.  Our infusion drinkers are lucky – as well as healthy herbs and spices -we use Green Tea as a base in all The Wise Herb Company infusions!

Antioxidant and Periodontal Health

Green tea is rich in health-promoting flavonoids. We have seen on this website how catechins and similar polyphenols like epigallocatechin-3-gallate can have anticancer and antioxidant health benefits.

The authors of this paper (Chatterjee et al) suggest that catechins should be considered right alongside of the better-known antioxidants like vitamins E and C as potent free radical scavengers and health-supportive for this reason.

Green tea has also been touted as having beneftis for periodontal health by reducing inflammation, preventing bone resorption and limiting the growth of certain bacteria associated with periodontal diseases.

Reduced risk of Cancer

Nechuta et al investigated the association of regular tea intake with risk of digestive system cancers in a population-based prospective cohort study of middle-aged and older Chinese women who were recruited in 1996-2000. An inverse association was found primarily for colorectal and stomach/esophageal cancers.

In conclusion, this large population study, tea consumption was associated with reduced risk of colorectal and stomach/esophageal cancers in Chinese women.

In a similar study by Wang et al, a meta-analysis showed that green tea may have a protective effect on bladder cancer (Asia).

A review by Khan & Mukhtar was conducted on Green tea catechins (epigallocatechin-3-gallate – EGCG) on its prostate cancer preventive properties. In their review article, they present available scientific literature about the effects of Green Tea Polyphenols and EGCG on signaling pathways in Prostate Cancer.

Learning, Hypertension and Cognitive Function

Cognitive dysfunction can occur via oxidative processes. Green tea catechins ((-)-epigallocatechin-3-gallate (EGCG)) were studied by Wang et al to evaluate the impact of hypertension in an animal model system on locomotor activity, learning, and memory.

EGCG treatment decreased the increased level of lipid peroxide production in a hypertensive animal model. These and other results suggest a therapeutic effect of EGCG in treating hypertension-induced learning and memory impairment, most probably through its powerful antioxidative properties.
