Have you tasted Chinese green tea? As you all know, green tea is the most popular types of Chinese tea. Many people, not only Chinese, consider it as the best drink for sultry summers. The main reason for this claim is the fact that green tea is cool and fights off inflammation.  Many have even claimed that it relieves fever.

Actually, the health benefits of Chinese green tea have been known throughout the world. The Chinese have known about these medicinal benefits since ancient times, as they have been using green tea to treat everything from headaches to depression. A writer named Nadine Taylor in her book Green Tea: The Natural Secret for a Healthier Life mentioned that green tea has been used as a medicine in China for at least 4,000 years.

These days, numerous scientific researches conducted both in Asia and the West is providing hard evidence for the health benefits long associated with drinking green tea. To mention, the Journal of the National Cancer Institute published the results of an epidemiological study in 1994, indicating that drinking Chinese green tea lowers the risk of esophageal cancer in Chinese men and women by nearly 60 percent. Also, it was reported by the researches of the University of Purdue just recently that a compound in green tea inhibits the growth of cancer cells.

There are other medical conditions to which drinking green tea is reputed to be beneficial.  To sum up, these conditions include cancer, cardiovascular disease, infection, rheumatoid arthritis, impaired immune function, and even high cholesterol levels.

What Makes Green Tea Special?

The top secret of Chinese green tea lies in the fact that it is rich in catechin polyphenols, particularly the said epigallocatechin gallate (EGCG). EGCG is basically an anti-oxidant that has the power to fight and kill cancer cells without harming healthy tissue in the body.  Studies also revealed that this anti-oxidant has been effective in lowering LDL cholesterol levels and hampering the abnormal formation of blood clots. The latter benefit takes on added importance for the fact that the formation of abnormal blood clots, medically known as thrombosis, is the main factor that causes stroke and heart attacks.

Furthermore, the effects of Chinese green tea and the “French Paradox” were highly associated.  Researches were in the first place puzzled by the fact that despite consuming a diet rich in fat, the French have a less incidence of heart disease than Americans. The primary answer was found to lie in red wine, which contains resveratrol. Resveratrol is a polyphenol that restricts the negative effects of smoking as well as a fatty diet. However, in 1997, a certain study reported that EGCG is twice as powerful as resveratrol. And, this somehow explains the lower rate of heart disease among Chinese men even though approximately 70 percent are smokers.

Other Benefits

New evidence that reveals the other benefits of Chinese green tea are now emerging. One of those is the claim that Chinese green tea can help dieters. Researches found that men who were given a combination of caffeine and green tea extract burned more fats than those given only a placebo and caffeine.

Chinese green tea is also said to prevent tooth decay. Just as its bacteria-destroying abilities can help prevent food poisoning, it can also fight the bacteria that cause dental plaque.

Today, several skin preparations containing green tea, from deodorants to creams, are also starting to appear on the market. This is for the reason that Chinese green tea is found out to be powerful in fighting bacteria that cause skin imperfections.

Miracle Cup: The Health Benefits of GREEN TEA

How do you fit a miracle in a cup?

For 4,000 years, the Chinese people have been using green tea as treatment for everything from headaches to depression.

Today, studies are conducted in Asia and the west in order to produce hard evidence of the health benefits of green tea. In the 1994 edition of the Journal of National Cancer Institute, the results of an epidemiological study stated that one of the health benefits of drinking green tea is that it can reduce the risk of esophageal cancer in Chinese men and women by up to 60%.

The rich presence of catechin polyphenols, particularly epigallocatechin gallate (EGCG) is the reason why green tea has so much health benefits. A powerful antioxidant, EGCG can not only inhibit the growth of cancer cells but can also destroy them without harming healthy cells.

The University of Purdue has also concluded a research on how a certain compound present in green tea can stop cancer cells from growing. Still another health benefit of green tea is its ability to lower down cholesterol levels and improve the ratio between good (HDL) cholesterol and bad (LDL) cholesterol.

The EGCG in green tea is a health benefit substance that can lower down LDL cholesterol levels and stop blood from forming abnormal clots (thrombosis), a leading cause of heart attacks and strokes.

Green tea has more health benefits compared to other Chinese teas like oolong and black tea, all of which come from the plant Camellia sinensis. What makes green tea different is the process by which it is made. Green tea owes much of its health benefits to how the Camellia sinensis leaves are steamed. The steam process keeps the EGCG health benefit of green tea from oxidizing. With oolong and black teas, however, the leaves are fermented instead of being steamed, thus causing the EGCG health benefit to transform into another less medicinally potent form.

Aside from medicinal value, green tea can also offer other health benefits, especially in the fitness field. Drinking green tea can cause a person to burn down more calories. A recent study on the health benefits of green tea shows that the drink can help dieters. According to the American Journal of Clinical Nutrition in 1999, men who take both caffeine and green tea burn down more calories than men who only take caffeine or a placebo.

Another health benefit of green tea is its bacteria-destroying properties. The health benefit of green tea in this area is that it can help prevent food poisoning and also prevent tooth decay. The substances found in green tea kill the bacteria causing food poisoning and those that cause dental plaque to form.

Well known for its countless medicinal and health benefits, green tea is nothing short of a miracle.

Study on GREEN TEA and Weight Loss

For many years now, several benefits are attributed to drinking green tea. Today, researchers have come up with newer proofs to solidify the belief that green tea can be used as a treatment for obesity and for weight loss.

It is held that more than half of the American population have weight problems or are obese. Conditions like these are almost always linked to certain complications like heart disease, type 2 diabetes mellitus, sleep apnea, gall bladder disease, and hypertension. Weight loss can aid in assuaging the symptoms of some of these conditions.

Scientists have tirelessly investigated on the weight loss benefits of green tea. They have found that green tea can actually enhance the total amount of energy spent by the body. From their findings, they were able to deduce that green tea has great potential for a weight loss benefit.

Other researches were able to confirm the weight loss benefit of green tea. A recent study at the University of Geneva had the conclusion that, “Green tea has thermogenic properties and promotes fat oxidation beyond that explained by its caffeine content per se.” Where before it was generally believed that the caffeine content in green tea is the reason for its weight loss benefit, this recent study deviated from that theory. Green tea has other substances in them that are helpful in weight loss.

The same team who conducted the study on green tea’s caffeine content and weight loss banded together in Switzerland to perform another experiment. They were still able to come up with the same results – that green tea has several thermogenic attributes that make it perfect to use in any weight loss program.

Sample Studies: Green Tea and Weight Loss

This particular green tea is Xu Fu Long Ya, a fine Chinese green tea from Sichuan. This is a representational visual reference of a large percentage of fine Chinese green tea, though there are varieties that can be different. The infusion colour is a result of a 1.5 minute duration, at 1 g of leaves to 100 ml of water at 70°C.

Green tea reduces body fat accretion caused by high-fat diet in rats through beta-adrenoceptor activation of thermogenesis in brown adipose tissue. Conducted by chief scientist J.J. Choo of the Department of Food and Nutrition, Kunsan National University, this study aimed to find out if green tea can suppress body fat and to find out whether this suppression is connected with thermogenesis spurred by the body’s beta-adrenoceptor being activated.

To investigate the weight loss benefit of green tea on rats, the scientists placed their subjects on a high-fat diet and provided them with green tea extract. It was discovered that even though the rats were on a high-fat diet, the green tea extract counterbalanced fat gain without affecting the amount of energy they took in. Green tea was said to have shown some weight loss benefits in the fact that it can prevent fat from being stored, can increase protein levels, and promote thermogenesis by triggering beta-adrenoceptor to action.

Recent findings of green tea extract AR25 (Exolise) and its activity for the treatment of obesity. This study is a collaborative work between Doctors P. Chantre and D. Lairon of the Laboratoires Arkopharma in Carros, France. Published in the 2002 issue of Phytomedicine, this study aimed to find out if green tea extract has weight loss benefits and can be a potential cure for obesity. 

In their study, they used an 80% ethanolic concentrate in green tea extract with standardized 25% catechins. They tested the green tea extract and were able to find that it could directly inhibit gastric and pancreatic lipases. These enzymes are the primary cause of fat storage and by delaying their actions; green tea extract therefore exhibits a weight loss benefit that can help solve obesity problems.

It was also discovered in this study that green tea can stimulate thermogenesis. Given to moderately obese patients, the green tea extract was said to have caused a decrease in weight by 4.6% and a reduction of waist circumference by 4.48% after only three months. The findings of the study clearly implicate the weight loss benefits of green tea.
