Green Tea
Overview

Green tea is well known for its many health benefits. However, five or more cups of green tea is necessary to receive all the health protection that it offers. Green tea is available in many other forms, not just as a beverage. One can get green tea capsules or supplements - for a busy person, this may be just what you need, and will allow you to gain all the nutritional and medicinal benefits of the green tea simply by swallowing a pill.

Green tea capsules have a multitude of beneficial effects on the body. These include the ability to lower cholesterol levels and control high blood pressure, slowing the progression of arthritis, and protecting against cardiovascular diseases. The powerful antioxidants that green tea contains act to protect DNA from damage by harmful free radicals that may be increased by air pollution or other toxins. Green tea capsules help with weight loss as well, as the green tea jump-starts the metabolism and helps it to burn more calories and fat.

Studies show that green tea capsules may even help to prevent a number of types of cancer, including breast cancer and liver cancer. In the case of breast cancer, it prevents the growth and spreading of cancer cells, and contains chemicals that stop the chemical estrogen from acting to stimulate cancer cells. For much the same reasons, green tea capsules are often used to treat menopause as well. Research demonstrates that the use of green tea capsules helps to lessen the effects of menopause for women who use them.

As early as 1994 an article published by the Journal of the National Cancer Institute showed that a regular diet that included green tea could reduce the risks of esophageal cancer by as much as 60%. The study found that certain compounds found in green tea tended to inhibit the growth of cancer cells. Apparently it's the fact that green tea is high in an anti-oxidant known as "epigallocatechin gallate", or EGCG for short. Clinical tests show that EGCG not only inhibits the growth of new cancer cells, but it kills some existing cancer cells without harming normal cells.
