Hoofnagle, MD, director of the Liver Disease Research Branch at the National Institutes of Health. The potential risk of liver damage is one reason green tea extract is included on CR's list of 15 supplements you should never take.

Still, when it comes to losing weight, working a few cups of brewed green tea into your diet isn't necessarily a bad idea. If you don't add sugar, it's calorie-free and can be a good replacement for sugary drinks. Consumption of up to eight cups a day is believed to be safe, according to NIH, though people that are pregnant or breastfeeding should not have more than six cups daily to limit caffeine intake.

Compounds called catechins are often credited for green tea's cancer-fighting potential. These antioxidants have the ability to block the action of molecules called free radicals, which can cause changes in healthy cells that sometimes lead to cancer.

But there's no solid proof yet that the catechins in green tea help to prevent cancer in humans, despite some promising studies in test tubes and animals. In the Cochrane Library published a review of 51 studies that included a total of more than 1.

Each study investigated whether consuming green tea reduced the risk of developing specific types of cancer, including those of the breast, colon , oral cavity, liver, pancreas, and prostate. After scrutinizing the data, Boehm says, the evidence of a benefit wasn't strong enough to recommend using green tea to protect against cancer.

In a update to that review , the authors concluded that the evidence for a beneficial effect against cancer remains limited, with inconsistent results between studies. Some data suggests that green tea can reduce the risk of cardiovascular disease —a narrowing of the arteries that can lead to heart attack, chest pains, or stroke.

For example, in a study of more than 40, adults, researchers in Japan found that those who consumed five or more cups of green tea per day were 26 percent less likely to die of cardiovascular disease over an year period than those who drank just one cup per day.

Similarly, a study of 76, people published in the Journal of Epidemiology and Community Health in found that women who drank one to six cups of green tea per day had a reduced risk of dying of cardiovascular disease over an average of 13 years compared with those who drank none.

How might green tea protect the heart? Experts say it may reduce high cholesterol levels and high blood pressure , which are important factors in cardiovascular disease.

But while this is a potential benefit, it's not conclusive, and high doses of green tea can reduce the effectiveness of the drug nadolol, used to treat high blood pressure and heart problems, cautions NIH. To reduce your risk of diseases such as cancer and heart disease as well as keep your weight in check , he says, you need to eat a healthy diet that includes plenty of fruit, vegetables, and whole grains.

You should also exercise and avoid smoking. The bottom line: From what we know now, drinking a few cups of green tea a day is a perfectly healthy habit as long as it's not loaded with sugar and may have a few small benefits. But skip supplements. The evidence for any health boost is lacking, and there are potential risks.

This study also demonstrated a consistent trend of decreased total cholesterol, reaching 5. There was good tolerance of the treatment among subjects without any side effects or adverse events.

Significantly lower ghrelin levels and elevated adiponectin levels were detected in the study group than in the placebo group. Conclusion: 12 weeks of treatment with high-dose green tea extract resulted in significant weight loss, reduced waist circumference, and a consistent decrease in total cholesterol and LDL plasma levels without any side effects or adverse effects in women with central obesity.

The antiobestic mechanism of high-dose green tea extract might be associated in part with ghrelin secretion inhibition, leading to increased adiponectin levels.

To produce green tea, freshly harvested tea leaves are immediately steamed to prevent fermentation from taking place.

This process then yields a dry, stable product. The steaming process destroys the enzymes responsible for breaking down the color pigments in the green leaves and allows the tea to maintain its green color during the ensuing rolling and drying processes.

This process preserves the natural polyphenols, which holds all of the health-promoting properties [ R ]. Green tea has many proposed health benefits due to its antioxidant properties. Since green tea is not oxidized, unlike black tea or oolong tea , it naturally contains more health-boosting polyphenols antioxidants.

These polyphenols include flavanols, flavandiols, flavonoids, and phenolic acids. The majority of polyphenols are flavonols which also known as catechins [ R ]. The four kinds of catechins mainly found in green tea are epicatechin, epigallocatechin, epicatechingallate, and epigallocatechin gallate EGCG [ R ].

Of the many proposed health benefits of Green Tea Extract, research indicates that EGCG is the key catechin responsible for its weight loss benefits. In other words, EGCG boosts your metabolic rate.

Therefore, green tea extract can help you lose weight by utilizing your body fat for fuel and helping you burn more calories. The exact mechanism of action of EGCG is not directly known. However, EGCG is thought to have a direct effect on the sympathetic nervous system stimulation lipolysis, thus increasing fat oxidation.

During exercise fat oxidation rates increase fold, due to the energy demand of energy that your muscles require [ R ]. In a study published in the Journal Of Clinical Nutrition two studies were performed to determine if green tea extract can help with weight loss by promoting fat oxidation at rest and during moderately intense exercise.

In study B, 11 healthy men took an oral-glucose-tolerance test before and after supplementation. The research indicates that Green tea extract has a direct impact on fat oxidation, but what does that mean for weight loss?

Simply put, since Green tea extract increases fat oxidation, your body burns more body fat for fuel, and increases its energy expenditure, which translates into burning body fat and greater weight loss.

The main outcome measures were anthropometric measurements, lipid profiles, and obesity related hormone peptides including leptin, adiponectin, ghrelin, and insulin.
