Weight Loss Potential Of Green Tea Explored In Study
button sencha

(New York) 19 January 2011

A recent study has discovered that daily intake of green tea extract may increase energy and aid with weight loss.

The scientists from the University of Medicine, Berlin, recruited ten healthy overweight and obese men to participate in the randomized, placebo-controlled, double-blind crossover trial.

The men were randomly put into one of five supplement groups: Placebo, low-dose EGCG (300 mg), high-dose EGCG (600 mg), caffeine (200 mg), or EGCG plus caffeine (300 mg/200 mg). They took the supplements for three days, then had seven days of washing out their system before moving to the next group. All had attended each group by the end of the study.

The results showed that a daily dose of 300 mg of EGCG led to a 33% increase in fat oxidation, whilst a dose of 200 mg caffeine was linked to a 34.5% increase. When male subjects were given a combination of EGCG (300 mg) and caffeine (200 mg), fat oxidation increased by almost 50%, added the researchers.

Green tea catechins have been studied extensively for their potential in aiding weight loss, with the compound epigallocatechin gallate (EGCG) highlighted as the key element.

James Betz, founder and CEO of world leading bioceutical firm, Biotivia, said: "We have been researching the weight loss potential of green tea extract for a couple of years now and this study highlights research we have been working on with our weight loss formula, Bio Shape."

Bio Shape represents a new and powerful multi-faceted approach to the complex and difficult challenge of weight loss. By attacking the two root causes of weight gain, appetite and metabolism, Bio Shape is able to help those people who want to lose at least 15 pounds or more.

Bio Shape combines the six most effective and scientifically proven weight loss extracts into one product with a far higher potency and purity than any other supplement.

Consisting of resveratrol, Fucoxanthin, Organic green tea, chromium, Garcinia cambogia and Gymnema sylvestre, this potent combination works synergistcally with the body to help suppress appetite and aid in weight loss.

Betz continues: "If you are interested in increasing your daily energy level, or an aid to losing weight, Bio Shape could be of substantial value. Bio Shape is most effective in combination with a program of reasonable physical exercise, and dietary restraint."

Cigarette smoke damages DNA within minutes, selenium, green tea reduce the risk

(U.S.) 16 January 2011
Preventing the genetic damage smoking can cause Within minutes of being inhaled into the lungs cigarette smoke causes genetic mutations linked to lung cancer, according to a new study in the Chemical Research in Toxicology.

Stephen S. Hecht at the University of Minnesota in Minneapolis and colleagues added an isotope-labeled [D(10)]phenanthrene - a type of polycyclic aromatic hydrocarbon or PAH to cigarettes and then let 12 volunteers smoke the cigarettes.  The isotope-labeled chemical is used for the researchers to track its fate in the human body.

Hecht found smokers developed a maximum serum level of a toxic substance known as [D(10)]r-1,t-2,3,c-4-tetrahydroxy-1,2,3,4-tetrahydrophenanthrene ([D(10)]PheT), which is known to damage DNA, just 15 to 30 minutes after cigarette smoke was inhaled.

PAHs are known harmful substances found in tobacco smoke.  Toxic matagenic and carcinogenic PAH diol epoxides can be derived from PAHS, which are responsible for most cases of lung cancer.

The study demonstrates harm is caused much faster than early thought.

The researchers concluded "the results clearly demonstrate immediate negative health consequences of smoking, which should serve as a major warning to anyone contemplating initiating tobacco use."

So how can cigarette smokers, or people exposed to second hand smoke,  lower the risk of lung cancer?

Taking selenium supplements may help.

A study reported this year in the FASEB Journal suggests taking dietary selenium supplements may help inhibit the formation of DNA adducts resulting from exposure to cigarette smoke.

Joshua Blake Martin and colleagues of University of Kentucky in Lexington, KY fortified three diets with 0.15, 0.5 or 2.0 mg/kg selenium in the form of sodium selenite and gave three groups of female mice half of whom were exposed to cigarette smoke six hours a day for five months. The other half were used as controls.

The researchers found mice exposed to smoke were more likely to develop tumors and mice fed the diet with 2.0 ppm selenium were less likely to develop tumors than those on the diet with 0.5 ppm Se.

Exposure to smoke boosted the growth of tumors and selenium could not stop the growth of lung can liver cancers.

The researchers concluded high levels of dietary selenium may inhibit the development of lung cancer.

Green tea may also help reduce smoke-induced lung cancer risk

Hakim I.A. and colleagues from University of Arizona in Tucson, AZ reported in the Aug 2008 issue of Journal of Nutrition that drinking green tea may help decrease DNA damage in smokers who are GSTM1 positive.

In the study, researchers assigned smokers to drink decaffeinated green tea, or black or water, measured urinary 8-hydroxydeoxyguanosine or 8-OHdG and found drinking four cups of tea per day was correlated with a significant decrease in urinary 8-OHdG among the green tea drinkers.

8-OHdG is believed to be one of the most abundant DNA lesions resulting from oxidative stress and is a biomarker of the oxidative DNA damage and repair. -- David Liu and editing by Aimee Keenan-Greene

White tea shows anti-cancer properties in the lab

 19 January 2011
  White tea (which isn't white in the cup) has anti-cancer properties in the laboratory, according to the National Center for Complementary and Alternative Medicine, a division of the National Institutes of Health.

"Although white tea comes from the same plant as green and black teas (Camellia sinensis), white tea goes through much less processing, resulting in a higher concentration of polyphenols," the report says. "While this study builds on previous laboratory research suggesting that tea - in particular, green tea - may have anti-tumor effects for certain cancers, there is no evidence yet that this laboratory research can be extended to treatments in people."

Chinese groceries throughout New England sell white tea.

"Researchers from the University of New Mexico, the University of California Los Angeles, and Scripps Green Hospital in La Jolla, Calif., treated two types of non-small cell lung cancer cells with white tea extract. This caused changes in both cell lines that led to cell death," according to the NIH. -- Tom Meade


More Cancer-Killing Compounds Found in Green Tea

21 January 2011
Green tea has long been studied for its anti-cancer effects with positive results.  But, new research published in the journal Cancer Science found there are two more reasons to drink green tea.

Many past studies of green tea have shown the effectiveness of on one particular nutrient called epigallocatechin gallate (EGCG).  But, in this exciting new study, researchers tested EGCG along with two additional plant nutrients found in green tea:  catechins catechin gallate (CG), and epicatechin gallate (ECG) against one of the most deadly types of cancer-pancreatic cancer.  They tested the three nutrients' ability to suppress cancer tumor growth and the inflammatory activity found in pancreatic tumor cells.

The results were impressive:  researchers found that ECGC effectively slowed tumor growth and reduced the cellular inflammation.  Even more impressive, the two other nutrients:  CG and ECG were substantially more effective than EGCG at halting the growth of tumors and reducing inflammation.

Their research may be helpful for those suffering from pancreatic (or potentially other) types of cancer but also in the prevention of cancer.  While there are benefits of supplementing with EGCG, it may be better to drink green tea regularly to benefit from its many phytonutrients, not just the best known one. -- Michelle Schoffro Cook

  2. In a large bowl, beat together sugar, oil, and eggs until smooth. Stir in 1 1/2 teaspoons vanilla. Beat in the flour mixture alternately with the yogurt, mixing just until incorporated. Pour batter into prepared pans.
  3. Bake in the preheated oven for 30 to 40 minutes, or until a toothpick inserted into the center of the cake comes out clean. Cool on wire rack for 30 minutes before turning out of the pans.
  4. To make Green Tea Frosting: Sift together confectioners' sugar and green tea powder. In a medium bowl, combine tea mixture with butter, cream cheese, vanilla and milk. Beat with an electric mixer until smooth.
  5. To assemble the cakes: when the cakes are completely cooled, put one layer on a flat serving plate. Spread a thin layer of frosting over it. Place the other layer of cake on top, and spread frosting to cover the top and sides of cake. Dust with green tea powder if desired. Serve cold or at room temperature.


Optional: 1 cup of adzuki beans (small red beans), soaked overnight and boiled until tender, can be folded into batter before it is put into the pans. Pat dry and allow to cool before use.
