Why is green tea so healthy?
by AMY ANDERSON, Daily Mail

It has just emerged that American doctors have developed a cream to ward off skin cancer. The magic ingredient is green tea, which is well known for its cancer-fighting properties.
Natural antioxidants called polyphenols in the tea help block the growth of skin cancer cells. In fact, green tea has a whole host of other health benefits.

Green tea helps burn fat
It can help speed up the metabolic rate because its antioxidant effect helps the liver to function more efficiently.
A recent U.S. study of overweight men found that, with no other changes to their diet or exercise regimes, drinking green tea three times a day burned up 200 extra calories a day. The green tea drinkers also found that their energy levels were greatly increased.

 
Green tea protects against heart disease
It has been shown to lower LDL (bad) cholesterol, because its potent antioxidant effects inhibit the oxidation of LDL cholesterol in the arteries.
The formation of abnormal blood clots (thrombosis) is the leading cause of heart attack and stroke, and green tea has been shown to inhibit abnormal blood clot formation as effectively as aspirin.

 
Green tea can help lower blood pressure
A major cause of hypertension (high blood pressure) is an enzyme secreted by the kidneys called angiotension- converting enzyme (ACE).
Popular drugs for hypertension act as ACE inhibitors: by blocking the effects of ACE, blood pressure is reduced. Green tea is a natural ACE inhibitor, and several medical studies show lowered blood pressure in animals and humans given green tea extracts.

 
Green tea can help protect against diabetes
When starch is consumed, it requires the enzyme amylase to break it down into simple sugars that can be absorbed in the bloodstream.
Green tea polyphenols inhibit amylase, and so can help lower blood sugar levels. High blood levels of glucose and insulin predispose people to diabetes.

 
Green tea can help prevent food poisoning
As it can kill bacteria, drinking green tea with meals may reduce the risk of bacterial food poisoning.
It prevents the growth of dangerous intestinal bacterial strains such as clostridia and E. coli and promotes the growth of friendly bifidobacteria.

 
Green tea can prevent bad breath
Drinking green tea – which is a natural anti-bacterial agent – with food may help kill the oral bacteria that cause cavities and bad breath.

 
Green tea guards against hepatitis
Viral hepatitis is often triggered by high levels of iron in the liver. Green tea lowers iron levels throughout the body, so may have a direct anti-viral effect against certain strains of hepatitis.

 
Green tea can protect against cancer
There is growing evidence to suggest that green tea contains compounds that fight cancer. The tea contains a compound called epigallocatechin-3-gallate (EGCG), which helps inhibit blood vessel growth.

 
Green tea can help prevent arthritis
A recent study found that antioxidants in green tea may prevent or reduce the severity of symptoms of rheumatoid arthritis.
Antioxidants in the tea inhibit the Cox-2 gene that triggers inflammation, working in much the same way as anti-inflammatory drugs.

Green tea improves your immunity
Gargling with green tea boosts immunity to influenza and flu, according to a study in Japan.
Research at Harvard University also indicated that green tea chemicals stimulated gammadelta T-cells, which bolster immunity against bacteria and viruses.

 
Green tea can protect against Alzheimer’s disease
A recent two-year study of a group of people aged 80 and over found that 96 per cent of those who drank ten cups of green tea a day showed no signs of cognitive impairment, compared to only 12 per cent who didn’t drink green tea.

 
Green tea can help fight allergies
Researchers in Japan have identified a compound in green tea that, in laboratory tests, blocks a key cell receptor involved in producing an allergic response.
The compound, methylated epigallocatechin gallate, works by blocking the production of histamine and immunoglobulin E, two compounds in the body that are chiefly involved in triggering and sustaining allergic reactions

Green Tea: The ‘Clean Caffeine’ Alternative to Coffee

An article on my favorite daily drink, Green Tea. I drink 5 cups of hot brewed Bigelow Green Tea a day. Since I started my Green Tea drinking my cholesterol, tri’s, and my diabetes 2 have all improved.

Many working Americans rely on a cup of coffee every morning to keep them alert throughout the day while two or three cups is enough for others. A few may need even more.

But is coffee really the healthiest choice? There are some benefits of coffee, such as reduced risk for Parkinson’s disease, skin cancer, colon cancer, diabetes, and even suicide. However there are quite a few disadvantages.

For starters, coffee discolors your teeth but it can also cause a number of more serious problems, such as hypoglycemia, high cholesterol, increased anxiety, fertility problems, increased risk of osteoporosis, dry skin, weight gain, addiction, and more.

So what can we do?

Green tea supplements are known to not only be a source of antioxidants but they give you a boost of energy that can last throughout the whole day.

Nutritionist Lola Berry of Australia says she is a huge fan of Green tea supplements and she takes them on a daily basis.

Green tea contains a special ingredient called epigallocatechin gallate (EGCG), a potent antioxidant that is believed to have therapeutic applications in the treatment of many disorders such as HIV, cancer, endometriosis, and Sjogren’s syndrome.

“These EGCG’s are also linked to speeding up our metabolism and stimulating the liver,” Lola Berry told Medical Daily.

“The liver is in charge of emulsifying fats,” she added.

Berry says green tea is also seen as a “great” weight loss supplement since it works on both the liver and metabolism at the same time.

Green tea supplements offer a number of health benefits such as cancer prevention and treatment, decrease of blood pressure, prevention of cardiovascular disease, stroke prevention, natural energy boost, and weight loss.

Berry sees green tea as a clear substitute for coffee.

“I love the stuff! I call it “clean caffeine” try to go for organic when you can!”

Green Tea Keeps Weight off – Study

I ran across this article on several sites and thought I would pass it along

There has never been a better time to go green, according to a team of US food scientists who say that green tea may slow weight gain and has the potential to play an integral role in the battle against obesity.

Publishing their findings in online journal Obesity, researchers from Pennsylvania State Universityfound that a control group of obese

Green Tea

mice who were fed Epigallocatechin-3-gallate (EGCG) – a compound found in most green teas – in addition to a high-fat diet gained weight 44 per cent slower than their counterparts who were fed the same diet without the compound.

“Our work suggests that EGCG inhibits an enzyme called pancreatic lipase (PL), which is secreted into the intestine when you eat and is the most important enzyme for the digestion of dietary fat,” explains study author Joshua Lambert, assistant professor of food science at Pennsylvania State University. “EGCG, in the test tube, inhibits this enzyme at relatively low concentrations. Definitely concentrations that are achieved in the intestine when you drink a cup or two of tea.”

The study also proposes that it could provide a cheap alternative to clinical weight-loss drugs, proving to be as effective while lacking the sometimes debilitating side effects. Though Lambert advocates drinking tea over the use of pills containing pure compounds, as human case studies have shown links between consumption of high doses of green tea-based dietary supplements and liver toxicity.

“We think this mechanism is relevant in animals, and probably in people, because mice treated with EGCG have elevated faecal fat content,” he adds. “To us, this suggests that the fat is not being digested, and is instead passing through the intestine and into the faeces. One pertinent point is the PL is the target for Orlistat [Australian trade name Xenical], a clinically used drug for weight loss.”

The findings support earlier research undertaken at the Department of Human Biology, Nutrition and Toxicology Research Institute at Maastricht University in the Netherlands. Scientists there conducted a meta-analysis of multiple studies on the effects of green tea on weight loss and weight maintenance in humans and concluded that its consumption “significantly decreased body weight and significantly maintained body weight” after a period of weight loss.

“It has only been scientifically evaluated in the past 11 years, and it is thought that the combination of EGCG and caffeine are responsible for the weight loss,” says Teresa Mitchell-Paterson, Head of Academic Studies (Natural Therapies) at the Australasian College of Natural Therapies. “However the consumption of caffeine alone does not give the same fat-loss benefit.”
