Do you drink tea? What is your favorite tea? How often do you drink it? Let’s have a little, “Tea Talk”. After water, tea is the most popular drink in the world. In addition to its great variety of tastes, drinking tea has been associated with many health benefits including prevention of heart disease and cancer.
So, what is the key ingredient for tea’s benefits?
Catechins — a potent and effective form of polyphenol antioxidants. Green tea is chemically characterized by its abundance in catechins. According to research, a typical cup of brewed green tea contains, by dry weight, 30–40% catechins, while equal amount of Oolong tea contains roughly 16% and black tea 3–10% catechins.
What is the science behind tea’s cancer protective effect?
Cancer protective benefits of tea catechins have been attributed to the following areas:
1. Antioxidant properties, which positively impact on the ability of the body’s cells to handle oxidative stress.
2. Enhancement on immune functions through its nutrients’ absorption and anti-microbial effect. Tea catechins can inhibit pathogen growth and modulate immune cells and inflammation markers.
3. Promotion of weight management through its effects on metabolism and metabolic enzymes. While increasing your metabolism, tea catechins also intensify fat oxidation and themogenesis, helping burn body fat naturally.
4. Protection against digestive and respiratory infections.
5. Inhibition on cancer cell growth, which is related to the diminished tumor growth and metastases observed from scientific studies.
In Bushman’s literature review (1998) on green tea and human cancer, which examined a total of 31 human studies and four reviews, the majority of these studies indicate that tea consumption is associated with reduced risks for cancers of the colon, urinary bladder, stomach, esophagus, pancreas and lung. New findings also showed that high consumption of green tea was closely associated with decreased numbers of lymph node metastases among pre-menopausal Stage I and II breast cancer patients.
Any substitute of green tea?
Sure. Tegreen 97, produced by Pharmanex, provides a highly concentrated, proprietary extract of green tea catechins. Each Tegreen 97 capsule contains the catechins equivalent of seven cups of green tea without the caffeine. With other polyphenol antioxidants as its constituents, Tegreen 97 is one of the most potent antioxidant products on the market, providing your body with maximum protection for critical cell structures such as DNA. Interestingly, studies from Pharmanex also showed that Tegreen 97 can have a significant beneficial effect in managing serious health conditions such as weight gain and need for blood sugar control.
It is recommended that consumers select a tea extract that is decaffeinated and standardized for total polyphenol contents and/or catechin concentrations. When shopping the tea market, please be aware of all of this. Also, Pharmanex Tegreen 97 meets all the criteria.
