What is a free radical & an antioxidant?

FREE RADICALS

A scientific explanation: In essence, a free radical is any molecular species capable of independent existence, that contains one or more unpaired electrons not contributing to intermolecular bonding, and is, in that sense, "free". They are produced by oxidation/reduction reactions, in which there is a transfer of only one electron at a time, or when a covalent bond is broken and one electron from each pair remains with each atom. Thus, a free radical has an unpaired electron.

Many free radicals are highly reactive, owing to the tendency of electrons to pair; that is, to pair by the receipt of an electron from an appropriate donor or to donate an electron to an appropriate acceptor. Whenever a free radical reacts with a non-radical, a chain reaction is initiated until two free radicals react and then terminate the propagation with a 2-electron bond, with each radical contributing its single unpaired electron. The free radicals of special interest in aging are the oxygen free radicals (OH., H., O2.-). These free radicals often take an electron away from a "target" molecule to pair with their single free electron; this is what is commonly termed “oxidation.?The term "reactive oxygen species" is used to refer to these oxidants and the oxygen free radicals.

In the human body, oxidized free radicals are believed to cause tissue damage at the cellular level, causing damage to our DNA, mitochondria (the powerhouse of the cell), and cell membrane, and have often been referred to as one of the causes attributed to aging, cancer, heart disease, and other human ailments. While the production of free radicals is a normal part of metabolism at the cellular level, things such as excessive alcohol intake, smoking, and various chemical exposures only serve to increase the amount of free radicals present in the body. To prevent free radical damage the body has a defense system of antioxidants.

ANTIOXIDANTS

Antioxidants are molecules which can safely interact with free radicals and terminate the chain reaction before vital molecules are damaged (as in Vitamin C), or seek out and scavenge free radicals (as in Vitamin E). This is where it can be noted that research has indicated that one of the main antioxidants found in green tea (epigalloctechin 3-gallate a.k.a. EGCG) has been found to be much more powerful than both Vitamins C and E. Compared to other known antioxidants, EGCG was found to be 100 times more effective than vitamin C, 25 times more effective than Vitamin E and twice as powerful as resveratrol at neutralizing free radicals.

Green Tea for Weight Loss!

There is no such thing as a "miracle" weight loss food or drug - however there are many indications that Green Tea brings a number of benefits to those trying lose weight:

Studies have also shown green tea extracts are capable of reducing fat digestion by inhibiting digestive enzymes. Others have shown thermogenic properties of green tea (probably brought on by the interaction between its caffeine content, and catechin polyphenols)Thermogenesis is the process of the body burning fuel (fat) without making chemical energy (the calories are released as heat).

However if you are overweight or obese - and change nothing else in your life except to start drinking green tea - you are not going to have an instant weight loss miracle! But the benefits to your health are not to be sniffed at.

Combined with other weight loss techniques, Green Tea (drink or extract) is an excellent addition to your diet.

History Of Tea

Tea was already mentioned in Chinese Literature as far back as 2700BC.
500 AD Buddhist Monks took leaf tea to Japan. 621 AD Buddhism was declared the major religion and green tea became the nation’s drink. In the 17th Century, tea reached the European landmarks via the famous Dutch East Indian Line. Following that, the English established their East Indian Line and created a tea monopoly for many years.

Camellia sinensis, the common tea plant, was first cultivated in the 4th century CE, after wild specimens were brought to China from India. Actually an evergreen tree which may grow up to 50 feet, the domesticated plant is pruned to a bush like state and kept at a height of five feet. After three to five years of growth, its leaves may be harvested to make tea. Today, women constitute the majority of pickers, and there is no machine that can exceed the 60 to 70 pounds of leaves per day that an experienced worker can collect. 60 to 70 pounds of fresh leaves can be produced app. 20 pounds of dry tea, or 2800 cups of tea.

All classes of tea, apart from the Rooibos tea, which grows in South Africa, come from the same plant. Different classes of tea (e.g. Black tea, Green tea) are the result of differences in the tea manufacturing process, and not due to different types of tea plants. However, from experience, tea manufacturers have discovered that certain varieties, locations and seasons tend to produce tea plants, which produce better qualities of certain classes of tea.

Why Tea?

Unlike coffee and soft drinks, tea is positively impacting us through better health and increased vitality.

Not only is tea soothing and delicious, but it is healthy too. Here are some benefits derived from the increase in consumption of teas:

  • The antioxidants in tea help prevent cancers of the mouth, stomach, pancreas, lungs, esophagus, colon, breast and prostate.
  • The antioxidants in a single cup of tea equal those in one serving of vegetables.
  • Scientific information from the USDA points out that drinking one cup of tea could make a significant contribution to daily antioxidant intake, equivalent to approximately one serving of vegetables.
  • Polyphenols, chemical components of tea, prevent both the growth of bacteria responsible for bad breath and the bacteria"s production of malodorous compounds.
  • Studies have shown that black tea suppresses the growth of bacteria in dental plaque and that rinsing with black tea reduces plaque formation and the production of acids that cause tooth decay.
  • In an experiment, people who drank five to six small cups of black tea daily for two weeks were better able to fight off bacterial infections, report the researchers in the early online edition of the Proceedings of the National Academy of Science.
  • EGCG is one of the most abundant and biologically active antioxidants found in tea. It is believed to be responsible for tea"s beneficial health effects. The compound is found in higher concentrations in green tea, the least processed of teas, than in black and oolong varieties.
  • Eating well Magazine named tea "Beverage of the Year" for its health benefits and mass appeal to consumers searching for an alternative to soft drinks and coffee.

Tea:
- Contains one-third the caffeine of coffee and cola
- Helps reduce fatigue and maintains mental alertness - Stabilizes fluid levels
