Green tea antioxidants are said to be hundred times more effective than vitamin E. Precisely for this reason it is very popular these days amongst health conscious community. Once you see the herb from health point of view, perhaps you should consider taking it in extract form rather than to take as a drink. Many people may not like the aroma. In fact the taste will be awful if one takes it in decaffeinated format.
All our diseases are due to immune deficiency. What do we mean by that? It is something like allowing weeds to spoil the wheat plants. Free radicals are the weeds in our body. They are the cells damaged and floating around to steal the lost proton from the good cells. Either they have to be scavenged or they have to be provided with a proton.
How cells are damaged? Oxidation is responsible. The oxygen what we inhale that is vital for our survival degenerates the cells. It is like rusting a metal or making a cut apple brown.
If you provide good nutrition to our body, the cells will get regenerated and our immune system will be healthy. For this our nutrition should have adequate quantity of antioxidants.
While all the foods we eat have nutrition and some quantity of antioxidants, there are few substances which are rich in antioxidants. The leaf from the plant camellia sinensis has substantial quantity of polyphenol catechin which is a great antioxidant. There is a bioflavonoid called epigallocatechin gallete (EGCG) present in catechin provides powerful green tea antioxidants. The quantum of the antioxidant in the leaf makes it very popular for good health reasons.
Cancer, arthritis, stroke, cardiac problems, cholesterol etc., are the result of weak immune system. Adequate antioxidants will provide strong immune system and one can postpone ageing, live a healthy life for a longer period.
In dried form, the leaf has 25% of catechin. Almost 50% of catechin is EGCG. In case you cannot relish the aroma of green tea, you should go in for capsules or pills to get the benefits of green tea antioxidants.
While there is no doubt about the antioxidants content in the leaf from camellia sinensis, it cannot be sole answer for proper immune system. One can get synergy out of different nutrition and find a permanent solution to maintain a good immune system provided the nutrition intake is seen from holistic point of view. I maintain a good immune system and lead a healthy life by taking a natural nutrition supplement which has all the nutrition required including the green tea antioxidants from camellia sinensis. I do not need to worry about the dosage etc., because they are added after extensive research done by reputed scientists. You should visit my website and I am sure you will benefit for a long and healthy life.

Green Tea Benefits - Effects on Eye Disease Prevention
Is there any condition that green tea won't benefit? In recent news, green tea consumption has been shown to help with glaucoma prevention. A study done by the University of Hong Kong tested the beverage on rats to observe the effects of the antioxidants on their eyes. The results indicated that, for up to 20 hours after green tea consumption, the antioxidants still had an effect of reducing oxidative stress on the eye. While, for humans, this may come as a result of drinking four or more cups per day, these benefits compound to those offered to weight loss, depression, and cancer prevention.
The study done by the University of Hong Kong consists of several rats being fed green tea overtime. Although the form of the tea - either in pill or liquid - isn't known, the antioxidant compounds in it appeared to reduce the oxidative stress in the rats' eyes during a period of 20 hours after consumption. More specifically, the catechins were found to be absorbed by several parts of the eye. The retina, for example, absorbed a large amount of gallocatechins, while the aqueous humor absorbed mostly epigallocatechins.
When applied to humans, this study indicates that the consumption of green tea can help prevent eye diseases like glaucoma that result from the oxidation of eye tissues. Essentially, as shown by the study, the eyes absorb the catechins - the antioxidants - found in the beverage. The effects aren't permanent, however. As the study indicates, the absorption of the catechins lasts for up to 20 hours. While this may be the entire time a person is awake and active, he or she will need to consume a few cups of tea the next morning - and every morning after - to continue receiving the same benefits.
Why is green the only type of tea that appears to have significant health benefits? Out of the three types, white tea hasn't been studied as often, although the antioxidants are higher, and black tea has been processed too much. Generally, teas keep more antioxidants with less processing. Because green tea is consumed more in parts of the world, its effects have been studied regularly for nearly 20 years.

Oxygen - the doubled edged sword
When we think of oxygen, what usually comes to mind is that it gives us life. And indeed it does!. We can live without water or food for several days but not with oxygen. We can survive only for a few minutes without it. But on the contrary, it is also a main ingredient for aging.
Iron rusts when exposed to oxygen. That's why water pipes made of iron are coated with a special material to protect the metal from coming in contact with oxygen. Scrape off the protective coating and for several hours you will notice the metal's color will slowly turn to brown. That's rust forming.
Slice an apple and a few minutes later, the flesh will turn brown.
But you may ask, why doesn't the apple skin react with oxygen destructively? The molecules which compose the apple's skin have tightly bonded electrons. They don't react with oxygen the way the flesh inside does.
There are atoms whose electrons are not tightly bonded to their nucleus. When they come in contact with oxygen, one of their electrons can be taken away from them because oxygen is like a magnet for electrons.
Oxidation is the term used for atoms which loses or gives up an electron to oxygen. Depending on the type of atom, it may become reactive or unstable( a free radical). The tendency of the atom now is to regain its stability by 'stealing' an electron from a nearby atom. A chain reaction occurs and it only stops when an antioxidant is encountered.
Free radical chain reactions occur frequently within our bodies. Without antioxidants, our cells will die rapidly, DNA would mutate which could alter the natural growth of cells, or put simply we will 'rust'.
Antioxidants are the 'defenders' to the harmful effects of oxygen when it combines with other molecules.
