For centuries green tea has held on strong to its reputation as an effective and trustworthy beverage packed with health benefits. Now researchers in Hong Kong have found new evidence that green tea may be good for our bones also.
Previous studies suggest that chemicals found in green tea can prevent heart disease and cancer [abnormal cells that divide without control, which can invade nearby tissues or spread through the bloodstream and lymphatic system to other parts of the body. ] , but this is the first time scientists looked into how these chemicals can prevent and treat osteoporosis.
Dr Ping Chung Leung and colleagues from the Institute of Chinese Medicine at the Chinese University of Hong Kong conducted a study to identify the chemicals that may help strengthen bones by stimulating their formation and slowing the process of weakening them.
Chemicals in green tea examined
In a laboratory experiment, the scientists exposed a group of cultured osteoblast-like rat cells to three main chemical ingredients found in green tea for several days. The chemicals were epigallocatechin (EGC), gallocatechin (GC), and gallocatechin gallate (GCG).
The scientists observed that the ingredient EGC in green tea boosted the level of a key enzyme that promotes bone growth by nearly 79 percent. In addition, they found that EGC increased the density of bone minerals in the cells. Bone mineralization makes the bones stronger, thereby reducing the risk of pain and fracture.
Another aspect highlighted by the study was that the activity of osteoclasts that weakens and breaks down bones was lowered by the high concentrations of ECG [a test that records the electrical activity of the heart, shows abnormal rhythms (arrhythmias or dysrhythmias), and detects heart muscle damage.]
Also, the researches noted that components of green tea did not have any toxic effects on the bone cells.
The researchers concluded that, "The tea catechins, EGC in particular, had positive effects on bone metabolism through a double process of promoting osteoblastic activity and inhibiting osteoclast differentiations."
Further research needed for concrete conclusions
Although green tea is packed with health benefits, experts feel there is a need for more research to establish its benefits for osteoporosis patients.
Claire Bowring of the National Osteoporosis Society states, "Some of these studies have suggested tea may have a positive effect on bone health but more research is needed before we can make any conclusions about actual benefits for people with osteoporosis. "Large scale clinical trials could help to determine if there is any fracture prevention benefits of these chemicals found in tea."The findings are published in the Journal of Agricultural and Food Chemistry.
Other health benefits of green tea
Green tea is known to heal and prevent processes that cater to diseases like cancer, heart disease, rheumatoid arthritis, infections, impaired immune functions, and cardiovascular diseases.
The benefits of green tea also involve improving the cholesterol rate in the body and hinder the formation of blood clots in wounds Next, drinking of green tea cleanses the human body of toxins that usually lead to a lot of health problems. It provides a wondrous feeling
of relaxation and energy.
People who make green tea a regular part of their lifestyle may significantly reduce their risk of death from heart disease and colorectal cancer. According to scientists in Japan, consuming seven cups of green tea daily for the long-term is necessary to gain this benefit.
The benefits of green tea have been reported by the Chinese since ancient times, when it was used to treat headache, depression, and a wide variety of ailments. Scientific research has since provided evidence to support some of the traditional claims, as well as new ones. In 1994, for example, a study published in the Journal of the National Cancer Institute reported that drinking green tea reduced the risk of esophageal cancer by nearly 60 percent. A more recent study (August 2009) reported that green tea could be helpful against bladder cancer. Green tea has also been credited with lowering cholesterol and helping with weight loss.
The current study from Japan evaluated 12,251 adults ages 65 to 84. The researchers found that compared with drinking less than one cup of green tea daily, people who drank seven or more cups daily reduced their risk of dying from heart disease by 75 percent. A reduction in the risk of colorectal cancer was 31 percent when comparing people who drank seven cups versus those who drank less than three cups of green tea daily. Over the 5.2 years of follow-up, 1,224 patients died: 400 due to cancer and 405 from cardiovascular disease.
The key to the secret of green tea’s positive impact on heart disease and colorectal cancer may be the high levels of polyphenols (30 to 40 percent) found in green tea, compared with only 3 to 10 percent found in black tea. Polyphenols are chemical substances, found in plants, that have antioxidant properties. The four main polyphenols in tea leaves are epigallocatechin gallate (EGCG), epigallocatechin (EGC), epicatechin gallate (ECG), and epicatechin (EC).

THE CHINESE have been sipping its benefits for centuries. Now the lowly tea leaf is getting the attention it deserves from the rest of the world. The green tea leaf, in particular, has been keenly eyed by nutrition experts. Its direct and indirect health benefits are sweeping, including its ability to reduce one’s risk of contracting colorectal cancer and heart disease, as well as promoting healthier bones.
Green tea contains plant compounds called epigallocatechin gallate (EGCG), which has been found to block the action of an enzyme breaking down noradrenaline which regulates many metabolic functions, including the heart rate and release of energy from fat. So by allowing more EGCG to stick around may actually boost metabolism, says certified nutrition specialist Jonny Bowden, PhD, in his book “The Most Effective Natural Cures on Earth.”
Rich in flavonoids Green tea leaves are rich in flavonoids and other compounds that may possess potent antioxidant properties. “Recent studies lend merit to the already substantial evidence that the polyphenols in green tea have anti-carcinogenic and anti-inflammatory properties,” states certified nutritional consultant Phyllis A. Balch in her book “Prescription for Dietary Wellness.” Recently, a more tantalizing study links green tea, as well as multivitamins, to gaining a younger biological age.
The article “Tea consumers may have younger biological age” by Stephen Daniells published online August 25 at nutraingredients.com states the Chinese University of Hong Kong reporting findings that cells of regular tea drinkers appear to exhibit a younger biological age than cells of non-drinkers.The article states that the researchers, led by Ruth Chan, noticed the telomeres of people who drank an average of three cups of tea per day were about 4.6 kilobases longer than people who drank an average of a quarter of a cup a day. This average difference in the telomere length corresponds to “approximately a difference of 5 years of life,” according to researchers.
Chinese green tea Chan also indicated that the data showed “a majority of Chinese tea consumed by our subjects were of green tea.” (The study is based on the telomere lengths of 976 Chinese men and 1,030 Chinese women aged over 65. The participants’ dietary habits were evaluated using a food frequency questionnaire).
Asked by Inquirer Health for his reaction, biochemistry, molecular and nutritional oncology specialist Doctor Romulo de Villa said the results of the study showed that longevity among green tea drinkers may, indeed, be due to the maintenance of telomere length and telomere sequence integrity of the DNA. He noted, that length and sequence were distinct.
“I agree with the experts that telomere length may be a marker of biological aging, meaning the shorter the length of the telomere the older the cell. However, there is no correlation of the length of the telomere with oxidative damage to the telomere sequence because length and sequence are two different things. Oxidative damage to the telomere may trigger early death of the cell or earlier apoptosis instead of a later time when the length of the telomere has been sufficiently shortened by successive rounds of cell proliferation, triggering apoptosis,” he said.
Green tea capsules “It’s true that green tea contains 30 to 40 percent of water-extractable polyphenols. There are pharmaceutical-grade green tea capsules containing 97 percent polyphenols which I am personally taking daily,” he stressed.
De Villa, who is currently the dean of Pamantasan ng Lungsod ng Maynila College of Medicine, added: “The finding that telomere length was longer in regular multivitamin users encourages me to continue taking my multivitamin, multimineral and multiphytonutrient food supplement daily.”
Daniells’ article also cited that recent researchers from the US National Institute of Environmental Health Sciences reported that telomere length was longer in regular multivitamin users in their cohort of 586 women aged between 35 and 74.
Green tea boosts heart health, prevents clogging of arteries

After Chinese food, it may well be time to adopt Chinese beverages too. Green tea – that golden liquid the Chinese drink in copious amounts – can keep your heart pumping smoothly longer, two new studies reveal.
In the first study, researchers from Okayama University in Japan reviewed questionnaires filled by over 12,000 Japanese and American subjects aged between 65 and 84 years on diet, tobacco/alcohol consumption and other details.
Green tea, heart health, prevents clogging of arteriesThe researchers tracked the subjects over a period of seven years, during which 1,200 died. An analysis of the questionnaires found green tea drinkers were less likely to have died in the period. Further, those who drank 420-560 millilitre green tea daily had a 75 percent lower chance of death due to cardiac problems than those drinking 1 cup or less daily.
The second study may explain the reason for these findings. Researchers from France and United Kingdom studied the effects of green tea on 60 hamsters and found the beverage had prevented fat from clogging arteries.
The researchers, from University of Glasgow in United Kingdom and University of Montpellier in France, kept the hamsters on a fat-rich diet for three months and gave them raspberry, strawberry, bilberry juices or green tea.
After the study period, hamsters on juices and green tea were found to have 79 to 96 percent less arterial clogging than their counterparts not given these beverages. The maximum benefit was seen in hamsters drinking green tea or raspberry juice.
Alan Crozier, lead author of the study from University of Glasgow, said, “Our findings suggest that taken as part of a healthy diet, berries and berry juices and teas may reduce the incidence of heart disease in humans. The teas we used were ordinary teas purchased from a local supermarket and the juices were also obtained from a local outlet. They are, therefore, both accessible and affordable for general public.” The Japanese study has been published in the journal Annals of Epidemiology and the European study in Food Chemistry.
A new study from German researchers shows that LED (light-emitting diode) skin therapy, combined with cream made from green tea extract erases wrinkles. The result of using the LED light and green tea extract treatment for smoothing facial wrinkles could produce an alternative to invasive Botox and cosmetic surgery.
The researchers used the combination wrinkle treatment for one month. One volunteer was used. According to the report, the LED light and green tea extract cream smoothes the skin, and resulted in “less pronounced wrinkle levels, shorter wrinkle valleys, and juvenile complexion.”
The LED light, green tea wrinkle therapy also worked ten times faster than using LED light that cause skin damage with overuse. The green tea extract, called green tea extract called epigallocatechin gallate, is a potent antioxidant. The combination of the two therapies reduced wrinkles
LED light therapy has recently been shown to reduce skin wrinkles, but also generates high levels of reactive oxygen species, that can lead to skin damage rather than wrinkle reduction.
The skin therapy reduced wrinkles in one-tenth the time needed if LED light therapy is used alone, providing a safe and effective skin wrinkle treatment. The researchers say the results could provide the framework for “an effective facial rejuvenation program” that works safely, and is non-invasive to reduce wrinkles, smooth the skin, and result in a more youthful appearance.
