When it comes to the amount of speculation, experimentation, research, clinical studies, and proven benefits of green tea, --it's almost intimidating getting to know all the facts. The main conclusion here is that green tea is good for you; it has anti-aging qualities, and prevents various illnesses. One example, and possibly the most serious of these kinds of health problems, is cancer. Cancer is one of the leading causes of early death currently. According to statistics, around three hundred people die of cancer every day, --and those numbers just cover the United States. But there's good news, because the antioxidants in green tea help prevent various kinds cancer, among other health problems.
Green Tea & Lung Cancer
Most forms of cancer are preventable, --not curable, but preventable, through clean living, not smoking, and basically, just keeping your body in good condition. And we all admit, that's easier said than done. Not everyone wants to wear sunscreen, even though it can prevent melanoma, and not everyone wants to quit smoking, --even though smoking is the leading cause of lung cancer. As it turns out, green tea might even be able to help smokers protect themselves from lung cancer.
Research on Green Teas Preventative Qualities
The scientists at the Toxicology Research Center in Korea have studied the effect of green tea on the lungs; they've found that it may protect the delicate tissues of the lungs, even under the heavy damage done by smoking. The four groups tested in the study were smokers consuming green tea, smokers who consume coffee, non-smokers, and smokers who consumed neither green tea nor coffee; all the smoking participants had been smoking for around 13 years. Rest assured, they weren't working with people who had just bought their first pack of smokes.
After six months of drinking 2 or 3 cups of green tea every day, the smokers returned, along with the other groups, for evaluation. This group, showed about as much SCE, (sister chromatid exchange) as non-smokers, making a significant reduction. This was the stand-out result; the other three groups weren't as impressive. SCE, by the way, is a cell process that is linked to the growth of tumors. Obviously, if green tea reduces the growth of tumors in the lungs, it's going to start becoming a lot more popular with smokers.
How You Can Stay Healthy with Green Tea
The scientists conducting the study concluded the same thing; smart guys, aren't they, --that green tea was preventative of lung cancer, even among smokers. And drinking coffee has no real effect on SCE levels, --so if you were worried that coffee causes cancer, feel free to keep drinking it. On the other hand, you may want to switch to some high quality green tea instead. It has just become extremely important that smokers drink green tea, --but not just people who smoke. Everyone is at risk for various kinds of cancers, so if green tea can actually help us prevent cancer and keep our bodies in good shape, we need to be drinking more.
Many people around the world, including chefs and even scientists believe that white tea has numerous benefits towards everyone’s health. But do you really know what exactly white tea is and how you could benefit from white tea leaves? The immature tea leaves are alternatively called white tea. These loose leaves are picked from the tea plant just before the plant has fully bloomed. The name ‘white tea’ came from the fine silvery fuzz covering the tea leaf and making it white in color. The four distinct varieties of white tea include the White Peony, Silver Needle, Long Life Eyebrow and Tribute Eyebrow. The difference between them is the proportion in which the tea leaves are blended with the tea buds.
Harvesting White Tea
Usually buds turn into tea in two days after they are picked. When two tea leaves are mixed with one tea bud, it forms the White Peony and if the mixture is made completely of buds, it is termed as the Silver Needle tea. The low quality tea variety called Long Life Eyebrow is made by mixing up the left over leaves after the White Peony and Silver Needle harvest. Tribute Eyebrow is processed using a special tea bush and is also a lesser quality tea. All four white teas can be purchased in loose leaf forms. On the other hand, teas available in bags have comparatively less quality and flavor than white tea. Tea bags are generally tea leaf dusts that remains at the bottom of tea bins after harvesting, reducing the desired quality and flavor.
White Tea Research
Scientific research has also shown that white tea provides additional protection against skin cancer, colon cancer, stomach cancer and even prostate cancer. Studies on the effect of white tea extract on skin exposed to direct sunlight has shown improved protection and reduced cell damage. A partially repaired immune system was also observed in some test subjects that consumed white tea leaves. Scientists found a wealth of antioxidants present in white tea and they suggested it may have anti-aging effect. Some compelling evidence has also been found in the direction of disease prevention using white tea leaves. It is shown that the white tea leaf extract may have the ability to stop pneumonia and the bacteria that causes Staph infection. It is also used to prevent tooth decay, gum disease, plaque and even bad breath.
What Else Can White Tea Do for You?
It is also believed that white tea leaf has anti-fungal effects. Recent studies have shown that some fungal types became inactive when the fungal drugs are consumed along with white tea leaves. Results of this study also show that white tea leaves might be used to prevent the fungus growth in certain similar conditions. Cholesterol is a health requirement and there are two kinds of cholesterol: good cholesterol and bad cholesterol. It is the bad cholesterol that causes the hardening of the arteries that could lead to heart attack. A type of antioxidants called catechins has been found to reduce bad cholesterol; white tea also helps raise the good cholesterol in the human body. It has been suggested that white tea leaves could lower the blood sugar levels, and thus reduce the occurrence of diabetic symptoms. More scientific research and results can be expected in the near future as the research on white tea continues.
Westerners have recently rediscovered the green tea. It has its origin in China; the Chinese believe that green tea has the ability to prevent many hazardous diseases, and even treat symptoms of others. This belief has now passed on to the western world, through word of mouth, and of course, the most well-known promotional tool in the world: the Internet. The west is now slowly adapting to the taste of green tea instead of black tea; not everyone likes the idea of 'green' tea, but the color is paler, not green, and the flavor is crisper. Green tea is made from a leaf called Camellia Sinensis, most commonly. These leaves do not require a high amount of oxidation and which makes green tea a good source of the antioxidants known as “Catechins”.
Antioxidants & Catechins
Antioxidants are agents that fight free radicals in the body. Free radicals can cause cell damage and a number of other diseases, --free radicals, are abnormal foreign agents, in some cases, and they are linked to the development of various kinds of cancer. Catechin in green tea is what gives it the strong taste and smell. Catechin also has the capability to move up to infiltrate our body's natural digestive system. It once absorbed by our digestive system, it’s filtered through the blood, where it eventually, reaches our retina, and eyes. The catechins then protect the eyes and reduce the occurrence of eye diseases. Research has been done on whether or not green tea can prevent glaucoma; the findings are pretty amazing. Glaucoma is a disease that can cause loss of eyesight, visual impairment, and even permanent blindness.
How it Works
An experiment was conducted on mice to prove that green tea can fight eye ailments. The tiny animals were fed green tea orally on a regular basis, and then their eye tissues were analyzed. The analysis revealed that the retina absorbed the highest number of catechins. The antioxidant lowered the harmful oxidative pressure in the eye and the effect lasted for about twenty hours. Many people are also aware of green tea's effect on weight loss; everyone seems to be jumping on some kind of green tea fad diet. Well, these diets aren't just trendy, 'here today, gone tomorrow', weight loss schemes. When used in your regular diet program and health regime it is extremely beneficial. People who replaced coffee for green tea rarely come back to coffee.
Add Green Tea for a Healthier Future!
Because of its medicinal values in the last few years Green tea has become an important subject of scientific research and analysis. These studies have proven that green tea also has other medicinal effects and benefits that help in reducing or preventing some hazardous diseases like cancer. Even more studies have proven that green tea may be effective in the treatment of joint diseases, like rheumatoid arthritis, or impaired immune disease and other serious illnesses associated with the liver. A cup of green tea is a good refresher and pumps in a high amount of energy in to the system, --and don't forget, it tastes great too!
Stroke - acute impairment of cerebral circulation, noticeably "rejuvenated" for the last decade. This medical emergency can be averted by having a few glasses of black or green tea a day. This statement was made by a group of American scientists from the University of California, studied nine researches on the subject. http://www.sciencedaily.com/releases/2009/02/090223091806.htm
In recent years, every twelve months, around the world more than six million people are diagnosed with a stroke. In peacetime, stroke causes the death of every third adult person, which means that is more frequent cause of death than a car accidents. Thus, every two out of ten cases of stroke happen to people under the age of fifty. There are very few ways to reduce the risk of stroke. According to lead author of study Lenore Arab, a professor of medicine, by the time a stroke victim receives medical care, it’s nearly too late to impede the damage. Another research found that 25 percent of people who had a stroke died within one year.
American scientists have collected and conducted nine large-scale studies on the relationship between regular consumption of green and black tea, and the risk of stroke. It appears that tea may be the prevention from this disease. The survey covered nearly 195,000 individuals of different sex, age, social status, and so on. This group of people in a certain period of time had 4,378 cases of stroke.
As the researchers found, people that regularly drink green or black tea two to three cups which is about three hundred milliliters of tea per day, the risk of stroke for them is reduced by 21%, compared to people who do not drink tea at all, or drink one cup a day or less.
The scientists suggest that the whole matter in the substances contained in tea, and plan soon to conduct a series of clinical trials to confirm the findings.
