Antioxidant Effects of Green Tea

Aug 17, 2007
Through the process of oxidation, oxygen starts the process of burning glucose and fat to provide heat and energy in the body. Although this is an inevitable and naturally occurring process which gives our bodies the energy we need; the process of oxidation creates some by-products that have negative effects to our body.

During the process of oxidation, highly reactive by-products called free radicals are produced. These free radicals act on other molecules, turning them into free radicals like themselves, thus disrupting their normal functioning. This could eventually lead to massive cell destruction, tissue damage, and even cause degenerative diseases, like cancer, heart disease, Alzheimer's disease, Parkinson's disease, rheumatoid arthritis and atherosclerosis among others.

Oxygen damage to your cells results when there are too many free radicals present inside the body. Researchers conclude that such damage may be partly responsible for the effects of aging and certain diseases.

There are certain substances in food which may play a role in protecting against this damage. Luckily, the human body comes prepared with natural defenses against these harmful free radicals.

Antioxidants are chemical substances found naturally in fruits and vegetables. Antioxidants act on free radicals, pursuing them and neutralizing them in order to stop their damage on healthy cells of the body.

What are the antioxidant effects of plants? Among the many plants that have disease-fighting antioxidants is the camellia sinensis, otherwise known as the tea plant. For centuries, tea has been served in Asian households as a healthy drink to promote health and general well-being. Green tea especially has been greatly favored due its many amazing health benefits.

For centuries, green tea has been consumed throughout the ages in Asia. In traditional Chinese and Indian medicine, green tea has been used as a stimulant, diuretic (to promote the excretion of urine), astringent (to control bleeding and help heal wounds), and to improve heart health.

The benefits of green tea have been largely attributed to the presence of polycatechins which have potent antioxidant effects. However, besides polycatechins, there are also other ingredients in green tea that contribute to its antioxidant effects.

What are the antioxidant effects found in green tea? Among all flavonoids, catechin is ranked high for its antioxidant effects and properties. Catechin is that substance in green tea which makes the beverage an excellent source of antioxidant effects. Besides tannin, vitamins such as vitamin A (carotene), C, and E, there are also other well-known substances in green tea that gives it its antioxidant effects.

Research aimed at finding the active compounds in green tea revealed that its defensive and antioxidant effects are mainly due to catechins which are powerful polyphenolic antioxidants.

Green tea also has antioxidant effects that make them powerful anti-carcinogenic, cardioprotective, nueroprotective, and anti-microbial actions. A mostly bioactive catechin called epigallocatechin gallate has been singled out by many researchers as very important because of its antioxidant effects leading to cancer prevention.

It is therefore a good idea to drink tea for its antioxidants effects. A constant intake of antioxidants from our diet can protect against damages to our body cells which occur following oxidation. Have more cups of green tea per day and benefit from its antioxidant effects.
