“Better to be deprived of food for three days, than tea for one.” (Ancient Chinese Proverb)

Is any other food or drink reported to have as many health benefits as green tea? The Chinese have known about the medicinal benefits of green tea since ancient times, using it to treat everything from headaches to depression. In her book Green Tea: The Natural Secret for a Healthier Life, Nadine Taylor states that green tea has been used as a medicine in China for at least 4,000 years.

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.

To sum up, here are just a few medical conditions in which drinking green tea is reputed to be helpful:

cancer
rheumatoid arthritis
high cholesterol levels
cariovascular disease
infection
impaired immune function

What makes green tea so special?

The secret of green tea lies in the fact it is rich in catechin polyphenols, particularly epigallocatechin gallate (EGCG). EGCG is a powerful anti-oxidant: besides inhibiting the growth of cancer cells, it kills cancer cells without harming healthy tissue. It has also been effective in lowering LDL cholesterol levels, and inhibiting the abnormal formation of blood clots. The latter takes on added importance when you consider that thrombosis (the formation of abnormal blood clots) is the leading cause of heart attacks and stroke.

Links are being made between the effects of drinking green tea and the “French Paradox.” For years, researchers were puzzled by the fact that, despite consuming a diet rich in fat, the French have a lower incidence of heart disease than Americans. The answer was found to lie in red wine, which contains resveratrol, a polyphenol that limits the negative effects of smoking and a fatty diet. In a 1997 study, researchers from the University of Kansas determined that EGCG is twice as powerful as resveratrol, which may explain why the rate of heart disease among Japanese men is quite low, even though approximately seventy-five percent are smokers.

Why don’t other Chinese teas have similar health-giving properties? Green, oolong, and black teas all come from the leaves of the Camellia sinensis plant. What sets green tea apart is the way it is processed. Green tea leaves are steamed, which prevents the EGCG compound from being oxidized. By contrast, black and oolong tea leaves are made from fermented leaves, which results in the EGCG being converted into other compounds that are not nearly as effective in preventing and fighting various diseases.

Other Benefits

New evidence is emerging that green tea can even help dieters. In November, 1999, the American Journal of Clinical Nutrition published the results of a study at the University of Geneva in Switzerland. Researchers found that men who were given a combination of caffeine and green tea extract burned more calories than those given only caffeine or a placebo.

Green tea can even help prevent tooth decay! Just as its bacteria-destroying abilities can help prevent food poisoning, it can also kill the bacteria that causes dental plaque. Meanwhile, skin preparations containing green tea – from deodorants to creams – are starting to appear on the market.

Harmful Effects?

To date, the only negative side effect reported from drinking green tea is insomnia due to the fact that it contains caffeine. However, green tea contains less caffeine than coffee: there are approximately thirty to sixty mg. of caffeine in six – eight ounces of tea, compared to over one-hundred mg. in eight ounces of coffee.

Since ancient times, green tea has been popular in Asian cultures like China and Japan. It is their beverage of choice because of its medicinal benefits. Its popularity has surged in the western hemisphere largely because of its proven ability to treat ailments such as headaches and depression. Dentist Burbank supports the scientific research regarding green tea and its health benefits. It has proven effective in fighting cancer, lowering high cholesterol levels, dealing with cardiovascular problems, ensuring immune infection, and preventing arthritis, among others. What makes green tea special is that it is rich in catechin polyphenols (epigallocathechin gallate or EGCG), which is an effective antioxidant. Green tea is known to prevent cancer and weight loss. It also inhibits abnormal formation of blood clots.

Dental Burbank believes that the study published by the American Academy of Periodontology (AAP) about green tea consumption should be taken seriously. Given the close links between dental health and overall health, it has been found that green tea also helps promote healthy teeth and gums by fighting periodontal diseases. According to Dentists Burbank, there are lots of information regarding the study done before by Japanese researchers when they analyzed 940 men focusing on their periodontal health. They found out that people who drank green tea regularly obtain good periodontal health.

There were three indicators examined regarding periodontal diseases. When green tea was consumed during the study, it was discovered that the periodontal pocket depth, attachment loss of gum tissue and bleeding on probing of the gum tissues (three indicators) decreased its potential on having periodontal disease. According to Cosmetic Irvine, the research has shown that the catechin, which is an antioxidant in green tea, helps promote good periodontal health. Catechin interferes in the body’s inflammatory response to periodontal bacteria. Because of this type of antioxidant, there is less chance of getting chronic inflammatory disease (periodontal disease) that affects gums and bones that support the teeth. DDS Irvine agreed with what Dr. David Cochran, DDS, PhD, President of the AAP and Chair of the Department of Periodontics at the University of Texas Health Science Center at San Antonio, when he said: “That is why it is so important to find simple ways to boost periodontal health, such as regularly drinking green tea – something already known to possess certain health-related benefits.”

Green tea helps promote periodontal health and prevents diseases closely associated with in periodontal diseases. This is because green tea interferes with our body’s response to periodontal bacteria. There are, however, concerns regarding the harmful effects of drinking green tea because it also has caffeine. Although it contains caffeine, which sometimes lead to insomnia (the only negative side effect reported), the caffeine content in tea is relatively small. Coffee, on the other hand, has more caffeine in its content compared to tea. Tea, therefore, is safe to drink. This is a beverage that is easy to find. It gives a lot of health benefits not only to our overall health but also to our dental health.
