Tea Cafein


This is due to caffeine, and caffeine has been a matter of controversy. It is a stimulant that has been shown to speed reaction time, increase alertness, and improveconcentration. The physical effects include stimulation of digestive juice, the kidneys, and the metabolism in ways that possibly help eliminate toxins.An increasing of mental alertness, shortening of reaction time, and improving
efficiency of muscle action is brought about by caffeine's stimulation of the heart and respiratory system, bringing more oxygen to the brain.

There has been much concern in the United States recently about the possible dangers of caffeine. As regards tea, it should be noted that all types of tea contain less caffeine than coffee. The caffeine content of some of our teas is available here. Caffeine tolerance varies greatly among individuals, and an excess of it is toxic. Some research has shown a possibility that caffeine can interfere with fetal development, including lowering birth weight and contributing to skeletal and other abnormalities. Until they reach the age of seven or eight months, babies cannot get rid of caffeine metabolites, and traces of caffeine can appear in breast milk too. Due to these concerns, pregnant and nursing mothers should limit or avoid any beverage with caffeine, including tea.

Caffeine content is also affected by the length of the infusion in water. Black tea infused for 5 minutes yields 40-100 milligrams, whereas a 3-minute infusion produces 20-40 milligrams, or half as much. Twenty cups of green tea yield 240 milligrams, or about 12 milligrams per cup.
Because tea bags contain broken leaves of smaller size, they produce an infusion with more caffeine than loose tea does. This is also true of very fine loose tea.

Health Benefits of Green Tea & Weight Loss


Today, scientific research in both Asia and the west is providing hard evidence for the health benefits long associated with drinking green tea. For example, in 1994 the Journal of the National Cancer Institute published the results of an epidemiological study indicating that drinking green tea reduced the risk of esophageal cancer in Chinese men and women by nearly sixty percent. University of Purdue researchers recently concluded that a compound in green tea inhibits the growth of cancer cells. There is also research indicating that drinking green tea lowers total cholesterol levels, as well as improving the ratio of good (HDL) cholesterol to bad (LDL) cholesterol. It has also shown fantastic results in contributing to weight loss and is included in many weight loss formulas.

Green Tea has long been valued in China for its miraculous medicinal properties for the maintenance of good health. It has been said in China "it is better to drink Green Tea than take medicine".

Green Tea has been receiving much attention lately. As a result, we now have many medical reports and studies by accredited institutions concluding that Green Tea does contain many healthful and healing properties. Drinking Green Tea has been shown to provide the human body with numerous health enhancing components. Green Tea contains a very high value of Catechin polyphenols that have antioxidant properties that are known to fight against cancer. In addition, Green Tea provides Polysaccharides, Flavonoids, Vitamin B complex, Vitamin C (there's more vitamin "C" in one cup of green tea than in an orange), Vitamin E, R-Amino Butyric Acid and Fluoride in it's natural state.

Recent studies conducted by Dr. Lester Mitscher, medicinal chemistry professor at the University of Kansas, concluded that green tea contains high concentrations of epigallocatechin gallate (EGCG), the strongest antioxidant. EGCG is over 100 times more effective in neutralizing free radicals than vitamin C and 25 times more powerful than vitamin E, which are great antioxidants for preventing cellular damage that leads to certain diseases, especially cancer.. EGCG tops other antioxidants, such as butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT) and resveratol.

Mitscher's comparison of green to Oolong and black tea showed green tea had a superior concentration of ECGC. The fact that processing of green tea is by a steam method is the influencial factor resulting in this diffenence. Although the amount of green tea consuption to prevent degenerative diseases aahs not been extablished, China and Japan have incidence of these type diseases. Most Orientals drink an average of four cups daily, however.

It is my opinion that American diet and life style may have a more negative effect in cellular degeneration compared to Orientals and this is why it may be more challenging to conduct studies properly in the USA. I believe a study should be conducted to identify various life styles to the consumption of green tea.

Did you know that drinking tea can help you lose weight? It’s true. Some teas can even help burn fat and calories. A recent scientific study supports green tea’s ability to burn fat and increase metabolism. What’s more, other studies show that, when combined with other sensible lifestyle choices like maintaining a healthy body weight, both green and black teas can help reduce the risk of heart disease, the #1 health risk for women. There are many flavored and herbla varieties of green tea available which make watching your weight a pure pleasure. Or kick the caffeine with a decaffeinated green tea.

Green tea has higher values of medicinal properties than other teas, because of the special way in which it is dried. This traditional drying technique prevents the tea from the negative effects of fermentation. The now widely recognized health benefits of Green Tea have been mentioned in many newspapers and journals including CNN, USA Today, New York Times, Chinese Daily News, Journal of National Cancer Institute, numerous US Universities and Research Centers. Some of the findings that have been established are:

GREEN TEA can help reduce the risks of esophageal, (the tube through which food passes from the pharynx to the stomach) skin and many other forms of Cancer, mainly by its highly significant antioxidant properties. (National Cancer Institute 1-800-4-Cancer).
