Drink to a healthy old age… with green tea: How beverage helps people stay fit

Green tea could help pensioners stay in the pink, according to a study.
Those who drank the beverage stayed more physically active than their peers, researchers found.
Coffee and standard tea did not provide this benefit.

Japanese researchers found that those who drank the most green tea were the least likely to develop ‘functional disability’
Researchers tracked the health of almost 14,000 men and women aged 65-plus for three years, noting what they ate and drank and factoring in data on any care they needed.
The more green tea they consumed, the more mobile and self-sufficient they were.
Those who got through at least five cups a day were 33 per cent less likely to develop a disability than those who drank less than one cup.
Three to four cups a day cut the risk by 25 per cent, the American Journal of Clinical Nutrition reported.
Green tea drinkers fared better as they grew older even taking into account that they generally had healthier diets, lower smoking rates, were better educated and had more friends and family to rely on, the Tokyo University study found.
It is not clear why green tea gives such a boost to health. But it does contain high levels of polyphenols, plant chemicals thought to cut cholesterol and protect DNA from damage.
These are found at much lower levels in normal tea or in coffee.

However, the study did not prove that green tea alone kept people spry as they grew older. Green-tea lovers generally also had healthier diets.

This Japanese study links green tea to staying agile as you grow older. But those who drink the hot drink also tend to have a better lifestyle including:

  • Healthier diets: Green tea-lovers tend to eat more fish, vegetables and fruit
  • More educated: Better informed about how to stay healthy
  • Lower smoking rates: Which could also account for fewer heart attacks and strokes
  • Greater mental sharpness
  • More socially active: With more friends and family to rely on

However, the drink should be avoided by those taking the blood-thinning drug warfarin as the vitamin K in it can stop the drug from working properly.

Yasutake Tomata of the Tohoku University Graduate School of Medicine and his colleagues followed nearly 14,000 adults aged 65 or older for three years.
They found those who drank the most green tea were the least likely to develop ‘functional disability’, or problems with daily activities and basic needs, such as dressing or bathing.
People who drank at least five cups a day were one-third less likely to develop disabilities than those who had less than a cup per day. Those people who averaged three or four cups a day had a 25 percent lower risk.
Although it’s not clear how green tea might offer a buffer against disability, Tomata’s team did note that one recent study found green tea extracts seem to boost leg muscle strength in older women.
While green tea and its extracts are considered safe in small amounts, though, they do contain caffeine and small amounts of vitamin K – which could interfere with drugs that prevent blood clotting.

Study shows fewer signs of aging in mice fed tea

Mice which were fed tea displayed fewer signs of ageing than mice that were fed water, with Oolong tea showing significantly better results than green tea.

If you are the type to fret over the appearance of wrinkles, age spots and other signs of growing old, oolong tea may be the answer to your worries. Details of the study, conducted jointly by scientists from America, Taiwan and Tokushima University in Japan, were given at the 17th International Congress of Nutrition in Vienna, Austria late last month. In the experiment, groups of six-month-old ‘senescence-accelerated mice’ (SAMs) were separately fed water, green tea and oolong tea over a 16-week period. SAMs age twice as quickly as ordinary laboratory mice. Checking hair loss, age spots, the condition of skin around the eyes and other indicators of ageing, the scientists found that male SAMs which were fed tea displayed fewer signs of ageing than mice that were fed water, with Oolong tea showing significantly better results than green tea.

Drinking Tea Might Delay Alzheimer’s Disease
3-4 cups of tea daily can improve the memory and help prevent Alzheimer’s disease. The research team, based at Newcastle University’s Medicinal Plant Research Center, investigated the properties of green and black tea, as well as coffee, in a series of laboratory experiments. The results showed that both types of tea inhibited the activity of enzymes associated with the development of Alzheimer’s disease. Coffee, however, had no significant effect. In fact, drinking tea appears to affect the brain in a similar way as drugs prescribed for Alzheimer’s disease the UK researchers report. According to scientists black and green brews fight enzymes that destroy chemical messengers in the brain. They said: “It’s exciting as tea is popular and inexpensive without side effects.”

Drinking Green Tea Protects the Brain
Regularly drinking green tea could protect the brain against developing Alzheimer’s and other forms of dementia, according to latest research by scientists at Newcastle University. Two compounds are known to play a significant role in the development of Alzheimer’s disease — hydrogen peroxide and a protein known as beta-amyloid… Previous studies have shown that compounds known as polyphenols, present in black and green tea, possess neuroprotective properties, binding with the toxic compounds and protecting the brain cells.

Green tea may be useful in controlling inflammation from injury or diseases such as arthritis.
Tea contains compounds that may help reduce inflammation and help arthritis. Scientists at Case Western University in Cleveland took two groups of mice and gave them injections of a substance that causes immune reactions similar to those due to rheumatoid arthritis. One group had regular water to drink and the other got water laced with polyphenols, chemicals found in green tea and, to a lesser extent in black tea. Nearly all the mice that drank regular water got arthritis-like symptoms, compared to less than half of the treated mice.

Little attention is paid to the health of our bones, until the unfortunate happens.

Maybe a nice cup tea could help in improving our bones’ resilience?

Tea Suitable for Bone Health
Resarchers state that three fundamental chemicals found in green tea- EGC, GC, and GCG have a great impact on osteoblasts, or bone cells when exposed to these particular chemicals. The bone cells treated with these particular chemicals helped stimulate growth in comparison to other components. In addition to promoting growth of cells, there was significant increased in the amount of mineralization found in the osteoblasts. Natural food sources, such as tea help offer an economical solution to the management of osteoporosis.

Tea Enhances Markers of Bone Health
Results show that consumption of GTP (at a level equivalent to about 4-6 cups of steeped green tea daily) and participation in tai chi independently enhanced markers of bone health by 3 and 6 months, respectively… Because oxidative stress is a main precursor to inflammation, this finding suggests that green tea and tai chi may help reduce the underlying etiology of not only osteoporosis, but other inflammatory diseases as well. Dr. Shen and colleagues concluded that there is a ‘favorable effect of modest green tea consumption on bone remodeling in this pre-osteoporotic population’ and hope to soon complete a more long-term study utilizing more technically savvy measures of bone density.

While medical researchers search for the magical ‘Golden Bullet’ for cancer, maybe tea can help in the meantime.

Several population-based clinical studies have shown that both green and black teas may help protect against cancer.
For example, cancer rates tend to be low in countries such as Japan where people regularly consume green tea. However, it is not possible to know for sure from these population-based studies whether green tea actually prevents cancer in people.
Early clinical studies suggest that the polyphenols in tea, especially green tea, may play an important role in the prevention of cancer. Researchers also believe that polyphenols help kill cancerous cells and stop them from growing.

Green tea extract may prevent breast cancer cells from manufacturing the new blood vessels necessary to promote cancer cell growth
Writing in a recent issue of the International Journal of Cancer, the USC researchers noted that the reduction in breast cancer risk among the green tea drinkers held true even among women who had a family history of breast cancer as well as among women who smoked or ate processed foods. Exercise habits – either good or bad – also did not play a role in the outcome for green tea drinkers. The conclusions of this study support the important results of a 2002 laboratory study. According to a report in Science News, researchers at the University of California and the University of Texas found that green tea extract may prevent breast cancer cells from manufacturing the new blood vessels necessary to promote cancer cell growth. If further research confirms these findings, it may help explain why the green tea drinkers in the USC study were at lower risk of breast cancer, regardless of other health, diet, and family history factors.

Bladder cancer
Only a few clinical studies have examined the relationship between bladder cancer and drinking tea. In one study that compared people with and without bladder cancer, researchers found that women who drank black tea and powdered green tea were less likely to develop bladder cancer. A follow-up clinical study by the same group of researchers revealed that people with bladder cancer — particularly men — who drank green tea had a better 5-year survival rate than those who did not.

Tea can fight against emerging cancer cells
“American scientists have found that drinking five small cups of tea a day can help to boost the immune system and possibly fight against emerging cancer cells. The alkylamine antigens present in tea, are also found in some bacteria, parasites, tumor cells and fungi. When the human immune system has previously been exposed to the antigen (by drinking tea), a much greater defense response is initiated against the bacteria, parasite, tumor or fungi.”

Study Shows How Green Tea May Fight Bladder Cancer
Green tea extract may interfere with a process that helps early bladder cancer to spread throughout the body, new laboratory research suggests. The findings, say researchers, bolster ongoing studies into green tea extract as a cancer treatment — and may give green tea drinkers more reason to savor every cup. The investigators found that when they exposed human bladder cells to both a cancer-causing chemical and green tea extract, the extract interfered with a particular process by which early cancer cells become invasive and spread throughout body tissue. This process involves the “remodeling” of actin, a structural protein in cells that is essential for cell movement. Actin remodeling allows cancer cells to move and invade nearby healthy tissue. Based on the new findings, green tea extract may get in the way of this process by activating a protein known as Rho, which helps regulate actin’s organization in cells and has been implicated in tumor development and progression.

Ovarian cancer
In a clinical study done with ovarian cancer patients in China, researchers found that women who drank at least one cup of green tea per day lived longer with the disease than those who didn’t drink green tea. In fact, those who drank the most tea, lived the longest. But other studies found no beneficial effects.

Breast cancer
Clinical studies in animals and test tubes suggest that polyphenols in green tea inhibit the growth of breast cancer cells. In one study of 472 women with various stages of breast cancer, researchers found that women who drank the most green tea had the least spread of cancer. It was especially true in premenopausal women in the early stages of breast cancer. They also found that women with early stages of the disease who drank at least 5 cups of tea every day before being diagnosed with cancer were less likely to have the cancer come back after they finished treatment. However, women with late stages of breast cancer had little or no improvement from drinking green tea.
There is no clear evidence one way or the other about green tea and breast cancer prevention. In one very large study, researchers found that drinking tea, green or any other type, was not associated with a reduced risk of breast cancer. However, when the researchers broke down the sample by age, they found that women under the age of 50 who consumed 3 or more cups of tea per day were 37% less likely to develop breast cancer compared to women who didn’t drink tea.

Compound can prevent diseased cells from growing
Spanish and British scientists have discovered how green tea helps to prevent certain types of cancer. Researchers at the University of Murcia in Spain and the John Innes Center in Norwich, England have shown that a compound called EGCG in green tea prevents cancer cells from growing by binding to a specific enzyme. “We have shown for the first time that EGCG, which is present in green tea at relatively high concentrations, inhibits the enzyme dihydrofolate reductase, which is a recognized, established target for anti-cancer drugs,” Professor Roger Thorneley, of JIC, told Reuters. “This is the first time, to our knowledge, a known target for an anti-cancer drug has been identified as being inhibited by EGCG,” he added. Green tea has about five times as much EGCG as regular tea, studies have shown. It decreased rates of certain cancers but scientists were not sure what compounds were involved or how they worked. Nor had they determined how much green tea a person would have to drink to have a beneficial effect, he said. – Reuters, Mar 2005

Colorectal cancer
Clinical studies on the effects of green tea on colon or rectal cancer have showed conflicting results. Some studies show decreased risk in those who drink the tea, while others show increased risk. In one study, women who drank 5 or more cups of green tea per day had a lower risk of colorectal cancer compared to non-tea-drinkers. There was no protective effect for men, however. Other studies show that drinking tea regularly may reduce the risk of colorectal cancer in women. More research is needed before researchers can recommend green tea for the prevention of colorectal cancer.

Esophageal cancer

Studies in laboratory animals have found that green tea polyphenols inhibit the growth of esophageal cancer cells. However, studies in people have produced conflicting findings. For example, one large-scale population-based clinical study found that green tea offered protection against the development of esophageal cancer, particularly among women. Another population-based clinical study found just the opposite — green tea consumption was associated with an increased risk of esophageal cancer. In fact, the stronger and hotter the tea, the greater the risk. Given these conflicting results, more research is needed before scientists can recommend green tea for the prevention of esophageal cancer.

Tea to Help Lower Risks of Lung Cancer
Results from research showed that both smokers and non-smokers who did not drink green tea were 5 times more likely to develop lung cancer compared to those who drank at least one cup of green tea per day. Smokers who did not drink green tea at all were more than 12 times more likely to be diagnosed with lung cancer than those who drank at least one cup a day. Green tea’s cancer fight capabilities are due to its rich concentration of polyphenols, notably a catechin called epiqgallocatechin-3-gallate, or as it’s more commonly known as ECGC. The studies don’t change the fact that smoking is bad for your health, and tea should not be an excuse to continue smoking.

Prostate cancer
Laboratory studies have found that green tea extracts prevent the growth of prostate cancer cells in test tubes. In a large clinical study in Southeast China researchers found that the risk of prostate cancer went down with increasing frequency, duration and quantity of green tea consumption. However, both green and black tea extracts also stimulated genes that cause cells to be less sensitive to chemotherapy drugs. People who are undergoing chemotherapy should ask their doctors before drinking green or black tea, or taking tea supplements.

Pancreatic cancer
In one large-scale clinical study researchers compared green tea drinkers with non-drinkers and found that those who drank the most tea were less likely to develop pancreatic cancer. This was particularly true for women — those who drank the most green tea were half as likely to develop pancreatic cancer as those who drank less tea. Men who drank the most tea were 37% less likely to develop pancreatic cancer.
However, it is not clear from this population-based study whether green tea is solely responsible for lowering pancreatic cancer risk. More studies in animals and people are needed before researchers can recommend green tea for the prevention of pancreatic cancer.

Stomach cancer
Laboratory studies have found that green tea polyphenols inhibit the growth of stomach cancer cells in test tubes, but studies in people have been less conclusive. In two studies that compared green tea drinkers with non-drinkers, researchers found that people who drank tea were about half as likely to develop stomach cancer and stomach inflammation as those who did not drink green tea. However, a clinical study with more than 26,000 men and women in Japan found no association between green tea and stomach cancer risk. Some studies even suggest that green tea may increase the risk of stomach cancer.

More clinical studies are underway to see whether green tea helps reduce the risk of stomach cancer.

Compound unique to black and oolong teas can kill cancer cells and reduce inflammation
Researchers from Rutgers University, NJ, studied theaflavin-2 (TF-2), a compound unique to black tea (and oolong), which has been shown to kill cancer cells, a process known as apoptosis. The TF-2 triggered cancer cell death, shrinking cancer cells within 3 hours of application. TF-2 appears to regulate or activate genes that kill cancer cells. In addition, it has the ability to suppress inflammatory enzymes and molecules. These results suggest that Theaflavin-2, a major component of black tea, has the capacity to help kill cancer cells through mechanisms involving both gene regulation and an anti-inflammatory effect.

Green Tea Helps Reduce Red in Rosacea
Green tea already is a favorite among fans of “natural” medicinal products. Now a cream made from an extract of freshly baked green tea leaves may be an effective treatment for a type of acne called papulopustular rosacea. Women treated with the green tea extract cream had a 70% improvement in rosacea compared with women treated with a placebo says Tanweer Syed, MD, PhD, an associate professor of dermatology at the University of San Francisco, Calif., who developed the tea extract. The study was presented at the American Academy of Dermatology meeting in San Francisco. RosaceaRosacea is a common skin condition which develops in phases. Typically, it starts with a tendency to blush — rosy cheeks or redness and swelling in the center of the face which can progress to papulopustular rosacea. Tiny pimples begin to appear in and around the red areas. Treatment can control the symptoms and prevent the condition from getting worse. Untreated, the condition can lead to chronic inflammation; the nose takes on the appearance of becoming red and enlarged. Syed tested the green tea extract cream in 60 women aged 25 to 50. All had visible signs of rosacea with papules and pustules as well as redness and swelling.

Can a wonderfully tasting drink actually help heart function?
Here are some published articles which suggest that it may actually do just that.
Drinking black tea may help blood pressure
Drinking black tea may lower the risk of heart disease because it prevents blood from clumping and forming clots. In a recent study, researchers found that while drinking black tea, the participants had lower levels of the blood protein associated with coagulation.

After a heart-attack, tea reduces the risk of dying by 44 percent.
Better to be deprived of food for three days than tea for one,” says a Chinese proverb. Research is showing it may just be true. Last week Dr. Kenneth Mukamal of Boston’s Beth Israel Deaconess Medical Center reported that out of i,900 heart-attack patients, those who drank two or more cups a day reduced their risks of dying over the next 3.8 years by 44 percent.

People who drank tea regularly had lower blood pressure than those who did not
“Blood pressure measurements were lower among the tea drinkers. The researchers calculated that the odds of developing hypertension were cut almost in half among those who drank one small cup a day, and by about two-thirds among those who drank 20 ounces or more daily. There was no difference between those who drank green and black tea.”

Hibiscus can help lower blood pressure
Studies show Hibiscus sabdariffa L., an ingredient found in many herbal tea blends has antioxidant properties, and have demonstrated antihypertensive properties. These results suggest daily consumption of hibiscus tea, in an amount readily incorporated into the diet, lowers BP in pre- and mildly hypertensive adults and may prove an effective component of the dietary changes recommended for people with these conditions.

Green tea consumption cuts risk of cardiovascular disease
A recent study carried out by researchers from Okayama University has shown that frequent consumption of green tea could contribute to lowering mortality due to cardiovascular disease. When the researchers compared tea consumption between people who drank one cup a days as opposed to seven or more cups a day, it was found that people who consumed more tea had a 55 and 75% lower risk of cause and mortality of CVD.

Beneficial Effects of Tea on Heart Disease Risk
More evidence for the beneficial effect of green tea on risk factors for heart disease has emerged in a new study [published in the European Journal of Cardiovascular Prevention and Rehabilitation]. The study found that the consumption of green tea rapidly improves the function of (endothelial) cells lining the circulatory system; endothelial dysfunction is a key event in the progression of atherosclerosis.

Liver disease
Population-based clinical studies have shown that men who drink more than 10 cups of green tea per day are less likely to develop liver problems. Green tea also seems to protect the liver from the damaging effects of toxic substances such as alcohol. Animal studies have shown that green tea helps protect against liver tumors in mice.
Results from several animal and human studies suggest that one of the polyphenols in green tea, known as catechin, may help treat viral hepatitis, an inflammation of the liver. In these studies, catechin was used by itself in very high amounts. It is not clear whether green tea, which has a lower concentration of catechins, would have the same benefits.
10 cups of green tea a day could cause problems because of the high level of caffeine consumed. Ask your doctor about the best way to include green tea in your treatment.

Our Immune System is constantly on guard against viruses and other invaders.
Tea can help bolster our ability to fight disease.

Drinking tea boosts the immune system’s first line of defense against infection
Results of a new study suggest that drinking tea boosts the immune system’s first line of defense against infection. Researchers from Harvard Medical School asked volunteers who normally consume neither tea nor coffee to drink five to six cups of tea or instant coffee for two or four weeks. Afterward, blood tests showed tea drinkers’ immune systems reacted against bacteria five times better than the immune systems of coffee drinkers. The tea seems to have helped make interferon gamma, an immune system protein. Next, the research team will study whether drinking tea actually protects people from getting sick. Another study, in mice, showed that animals genetically engineered to develop prostate cancer and fed the equivalent of about six cups of tea a day didn’t develop tumors. No one knows if drinking tea will have the same effect in humans, but researchers noted that the tea-drinking country of China has the lowest prostate cancer rate in the world. Results of both studies were reported at the American Chemical Society meeting on September 8, 2003.

Tea helps fight infection
“The [study] results gave clear proof that five cups of tea a day sharpened the body’s disease defenses, said Dr. Jack F. Bukowski, a researcher at Brigham and Women’s Hospital in Boston and Harvard Medical School. Dr. Bukowski and his co-authors isolated a substance called L-theanine from ordinary black tea. He said L-theanine was broken down in the liver to ethylamine, a molecule that primes the response of an immune system element called the gamma-delta T cell.”

Matcha green tea has many antioxidants
(Our Matcha green tea is known as Wirun tea)
For years, studies have indicated that the antioxidants in green tea offer protection against diseases, including cancer, and even fight dental cavities. One of the most beneficial of these antioxidants is called epigallocatechin gallate. At the University of Colorado at Colorado Springs, [scientiest] used the chemical separation technique known as micellar electrokinetic chromatography to analyze matcha and a green tea commonly available in U.S. markets. The researchers found that samples of matcha had 200 times the concentration of epigallocatechin gallate in the common U.S. tea. Although most green teas are prepared in the familiar way-by steeping leaves in water-matcha is prepared by mixing hot water with powdered leaves. This is probably why matcha contains so much epigallocatechin gallate.

Green tea could fight autoimmune disorders
Polyphenols founds in green tea may help protect the body autoimmune disorders, believes an oral biologist who has conducted extensive studies into their health promoting properties. Dr Stephen Hsu, a researcher at the Medical College of Georgia’s School of Dentistry, suspected that there may be a link between green tea consumption and autoimmunity after noting that dry mouth, or xerostamina, an autoimmune disorder suffered by around 30 percent of elderly Americans, occurs in only one to two percent of Chinese people in the same age group. Green tea is a common component of the typical Chinese diet. Autoimmune disorders occur when the immune system starts to attack the body’s own tissues. They may be triggered by other health conditions, such as type 1 diabetes, rheumatoid arthritis, lupus and Sjogren’s disease, and can have debilitating and even life threatening effects. Dr Hsu will present the findings of his latest investigations, involving green tea’s role in producing autoantigens, at the Arthritis research Conference in Atlanta this weekend. Autoantigens are molecules that have useful functions, but changes in their amount or location can trigger an immune response.

Green Tea Fights Superbugs
Green tea can help beat superbugs according to Egyptian scientists… The pharmacy researchers have shown that drinking green tea helps the action of important antibiotics in their fight against resistant superbugs, making them up to three times more effective… “In every single case green tea enhanced the bacteria-killing activity of the antibiotics,” [according to the researchers].

Mechanism Discovered for Health Benefit of Green Tea, New Approach to Autoimmune Disease

One of the beneficial compounds found in green tea [EGCG] has a powerful ability to increase the number of ‘regulatory T cells’ that play a key role in immune function and suppression of autoimmune disease, according to new research in the Linus Pauling Institute at Oregon State University. EGCG may have health benefits through an epigenetic mechanism, meaning we aren’t changing the underlying DNA codes, but just influencing what gets expressed, what cells get turned on,’ Ho said. ‘And we may be able to do this with a simple, whole-food approach.’ Laboratory studies done with mice, Ho said, showed that treatment with EGCG significantly increased the numbers and frequencies of regulatory T cells found in spleen and lymph notes, and in the process helped to control the immune response.

Reward yourself while losing weight!

Trying to lose weight? Another benefit of green tea!
Compared to the placebo and caffeine, green tea extract consumption produced a significant 4% increase in 24-hour energy expenditure. If you consume 2,000 calories per day and don’t gain or lose weight (you’re in energy balance), an increase of 4% would translate roughly into an 80-calorie daily difference. Over a year, this could result in 8 pounds of weight loss.

Daily intake of the tea burns extra calories
“In a 1999 Swiss study, six out of 10 men taking capsules of green tea extract burned, on average, about an extra 80 calories a day-the equivalent of 3 tablespoons of ice cream, 7 potato chips, or 1 Dunkin’ Donuts Munchkin. A second study, conducted by researchers from the US Department of Agriculture, saw an extra 67 calories a day burned in men who were assigned to drink about 5 cups of tea (not green) each day.”

Recent evidence shows that in the battle of fat loss, green tea may be superior to plain caffeine
According to a new study, green tea appears to accelerate calorie burning — including fat calories. Researchers suggest compounds in green tea called flavonoids may change how the body uses a hormone called norepinephrine, which then speeds the rate calories are burned.

Green Tea Helps Melt Off Pounds
Drinking just three cups a day of green tea seems to help you melt off extra pounds. A study by the USDA Human Nutrition Research Center on Aging at Tufts University found that participants who drank three cups of green tea a day lost twice as much weight as non-tea drinkers. A type of antioxidant known as catechins is credited with the weight-loss benefits of green tea. (Replacing a little tea brewing water with lime or lemon juice can help your body activate even more of the tea’s catechins.)

Green Tea Component Helps Decrease Body Weight
This study evaluated the influence of a green tea catechin beverage on body composition and fat distribution in overweight and obese adults during exercise-induced weight loss. There was a trend toward greater loss of body weight in the catechin group compared with the control group… These findings suggest that green tea catechin consumption enhances exercise-induced changes in abdominal fat and serum [triglycerides].

Weight loss
Clinical studies suggest that green tea extract may boost metabolism and help burn fat. One study found that the combination of green tea and caffeine improved weight loss and maintenance in people who were overweight and moderately obese. Some researchers think that substances in green tea known as catechins are responsible for the herb’s fat-burning effect.
