Health Benefits From Green Tea
The health benefits of green tea have been a subject matter of discussion amongst tea enthusiasts everywhere. Being a storehouse of many antioxidant compounds, its easy to assume that green tea is one of the healthiest beverages. In fact, traditional Chinese medicine has staunchly held that drinking green tea helps relieve body aches and pains, aids digestion, impacts the process of detoxification, and, generally, enhances the quality of life. Numerous recent studies have demonstrated that the aqueous extract of green tea polyphenols contains antimutagenic, antidiabetic, antibacterial, anti-inflammatory, and hypocholesterolemic properties.
In vitro studies and clinical trials that take into account biomarkers of oxidative stress provide strong evidence that green tea polyphenols can play an important role in reducing the risk of several chronic diseases, including prevention of cardiovascular diseases and cancer. Some studies have also tried to study the benefits of green tea on bone density, dental caries, and kidney function, and have come forward with promising results. However, results from epidemiological studies and in vivo clinical trials that try to establish a definite relationship between consuming green tea and human health are conflicting and inconclusive, at this point.

How To Consume Green Tea
The United Kingdom Tea Council recommends drinking not more than 6 cups of tea a day. For the best health benefits, 3 to 4 cups is recommended. However, doses of green tea vary significantly, but usually range between 1-5 cups daily is considered safe. The commonly used dose of green tea is based on the amount typically consumed in Asian countries, which is about 3 cups per day, providing 240-320 mg of the active ingredients, polyphenols. To make tea, people typically use 1 tsp of tea leaves in 8 ounces of boiling water.
Drink green tea when its freshly made but slightly cooled. Scalding tea can damage your digestive system. Moreover, recent studies suggest that too much hot tea can promote throat cancer. Compounds in tea like catechins, theanine, and vitamins C and B diminish over time through oxidation, so the health benefits are strongest with fresh tea. If youre brewing the same tea leaves, brew them in moderation. With each successive infusion, cancerous substances in the leaves themselves are drawn out and can even be toxic. Old tea can also harbour bacteria, especially since its antibacterial properties diminish with time.

The tea you use, temperature and steeping time all have a significant effect on the antioxidant levels of brewed green tea. Warm and ambient temperatures are the best to retain antioxidants. Let the boiling water cool slightly before pouring onto the tea leaves, and allow to steep for between 2 and 3 minutes.

A Primer On The Immune System
The immune system is composed of white blood cells, which are then differentiated into five different type of immune cells.;One of those is a group of cells called lymphocytes.
Lymphocytes are then broken down even further into B cells, as well as T cells, which have their own subset of cells called T helper cells, T regulatory cells, cytotoxic T cells and T suppressor cells.
The immune system can be confusing, so rather than describe these cells in detail, Ill use a real life example of how it works.
Lets say you cut yourself with a dirty knife.; Bacteria penetrate your skin, engaging a first line of defense from our immune system called a macrophage .
Macrophages are like big, fat security guards wielding tiny billy clubs – ineffective, but theyll slow an invader down while they call on more sophisticated security guards.
When confronted with an invader, macrophages call on their friends, the T helper cells. The T helper cells tell the entire immune system through a series of chemical signals that there has been an invader that has crossed the barrier.
Specifically, the T helper cells call directly on two types of cells, cytotoxic T cells and natural killer cells, both soldiers with muscle that live up to their name and help attack and kill the bacterial invaders.
Once the bacteria have been killed, it is time for the immune system to call off the attack, which is the job of the T suppressor cells, who suppress the fight.

Autoimmune Disease: An Immune System Out Of Balance
Virtually all autoimmune diseases – conditions where the immune system begins to attack self-tissue – have either a Th1 or a Th2 dominance.
Put another way, autoimmune conditions generally have either a T cell upregulation and B cell suppression or the opposite .
|Th1 dominant: T cells up; B cells down||Th2 dominant: T cells down; B cells up|
Its imperative that people with autoimmune disorders maintain Th1/Th2 balance.
When the immune system is dysregulated and starts attacking body tissues, the more out of balance the immune system is, the more voraciously it will attack those tissues.
For example, in someone with rheumatoid arthritis, an autoimmune condition where the immune system attacks cartilage, the more out of balance the Th1/Th2 system is, the more cartilage destruction will take place.

How Does Green Tea Indirectly Aid Weight Loss
One of the antioxidants present in green tea, Epigallocatechin Gallate or EGCG, helps stimulate the metabolism of the body. It stimulates the central nervous system which releases the fat into the bloodstream and the body uses the fat as fuel which produces extra energy. This sheds the extra water and also helps to burn fat.
There is some evidence that shows that EGCG helps reduce weight which is present in green tea. But if you believe that you can lose your pounds just by drinking tea then youve been misled.
Swapping cups of high caffeine and sugary teas and drinks with green tea helps keep a check on calorie intake. Drinking a number of cups of green tea also cuts down on your hunger, and since you feel like eating less, weight loss is definitely on the cards.
PS: One thing to remember though is that gulping down nine or ten cups of green tea isnt going to do much for you. Exercise and a healthy diet cannot be substituted with a cup of green tea to lose the extra fat in your body.
