Health Benefits of Green Sencha
3. Weight Loss
a. In the meta-analysis whether green tea indeed has a function in body weight regulation of the study of "The effects of green tea on weight loss and weight maintenance: a meta-analysis" by Hursel R, Viechtbauer W, Westerterp-Plantenga MS.[3a], researchers found that Catechins or an epigallocatechin gallate (EGCG)-caffeine mixture have a small positive effect on WL(weight loss) and WM(weight management) and suggested that habitual caffeine intake and ethnicity may be moderators, as they may influence the effect of catechins.
b. In the investigation of the effect of a green tea-caffeine mixture on weight maintenance(VM) after body weight loss in moderately obese subjects in relation to habitual caffeine intake of the study of " Body weight loss and weight maintenance in relation to habitual caffeine intake and green tea supplementation" by Westerterp-Plantenga MS, Lejeune MP, Kovacs EM.[3b], researchers filed the conclusion that high caffeine intake was associated with weight loss through thermogenesis and fat oxidation and with suppressed leptin in women. In habitual low caffeine consumers, the green tea-caffeine mixture improved WM, partly through thermogenesis and fat oxidation.
c. In the investigation of nutrition supplements that are claimed to acutely increase fat metabolism or energy expenditure of the study of "Fat burners: nutrition supplements that increase fat metabolism" by Jeukendrup AE, Randell R.[3c], researchers found that based on the available literature, caffeine and green tea have data to back up its fat metabolism-enhancing properties.
d. In the incestigation of alternative methods of modulating body weight and body fat of "The putative effects of green tea on body fat: an evaluation of the evidence and a review of the potential mechanisms" by Thavanesan N.[3d], researchers found that An evaluation of the available evidence supports a role of green tea in weight loss; however the extent of the effects obtained is still subject to debate, and requires more objective quantification in future researches.
e. In the examination that Green tea is associated with beneficial health effects mainly because of its body fat-reducing and hypocholesterolemic activities of the study of "Green tea aqueous extract reduces visceral fat and decreases protein availability in rats fed with a high-fat diet" by Bajerska J, Wozniewicz M, Jeszka J, Drzymala-Czyz S, Walkowiak J.[3e], researchers found that green tea aqueous extract (GTAE) may have preventive effects on the accumulation of visceral fat but only in higher doses. Although both doses improved cardiovascular risk indicators, they, in addition, significantly inhibited protein digestion.

b. Cancer prevention
In the evaluation of green tea extracts (Camellia sinensis Theaceae) and Inhibition of tumorigenesis of the study of "Cancer prevention by tea: Evidence from laboratory studies" by Yang CS, Wang H, Li GX, Yang Z, Guan F, Jin H.[2b], researchers indicated that many studies in cell lines have demonstrated the modulation of signal transduction and metabolic pathways by (-)-epigallocatechin-3-gallate (EGCG), the most abundant and active polyphenol in green tea. These molecular events can result in cellular changes, such as enhancement of apoptosis, suppression of cell proliferation, and inhibition of angiogenesis.
c. Breast cancer
In the examination of green tea catechin and Long-term exposure to low doses of environmental carcinogens contributes to sporadic human breast cancers of the study of "Green tea catechin intervention of reactive oxygen species-mediated ERK pathway activation and chronically-induced breast cell carcinogenesis" by Rathore K, Choudhary S, Odoi A, Robert Wang HC.[2c], researchers found that GTCs (green tea catechin), at non-cytotoxic levels, were able to suppress chronically-induced cellular carcinogenesis by blocking carcinogen-induced, ROS elevation, ERK activation, cell proliferation, and DNA damage in each exposure cycle. Our model may help accelerate the identification of preventive agents to intervene in carcinogenesis induced by long-term exposure to environmental carcinogens, thereby safely and effectively reducing the health risk of sporadic breast cancer.
d. Lung cancer
in the evavuation of the importance of the antioxidant activity of green tea and EGCG for their inhibitory activity against lung tumorigenesis of the study of "The prevention of lung cancer induced by a tobacco-specific carcinogen in rodents by green and black Tea" by Chung FL., [2d], researchers indicated that we have generated important new data that support green and black tea and caffeine as potential preventive agents against lung cancer.

Thus, EGCG likely provides an additional option for a new and potential drug approach for cervical cancer patients.
m. Pancreastic cancer
With an aim to evaluate the epigallocatechin gallate (EGCG) suppresses human pancreatic cancer cell proliferation of the study of 'Green tea epigallocatechin gallate exhibits anticancer effect in human pancreatic carcinoma cells via the inhibition of both focal adhesion kinase and insulin-like growth factor-I receptor' by Vu HA, Beppu Y, Chi HT, Sasaki K, Yamamoto H, Xinh PT, Tanii T, Hara Y, Watanabe T, Sato Y, Ohdomari I.[2m], researchers suggested that blocking FAK and IGF-1R by EGCG could prove valuable for targeted therapy, which can be used in combination with other therapies, for pancreatic cancer.
n. Bladder cancer
In the examination of the antioxidant effect on bladder cancer cells of the study of "Antioxidant effects of green tea and its polyphenols on bladder cells" by Coyle CH, Philips BJ, Morrisroe SN, Chancellor MB, Yoshimura N.[2n], researchers found that urothelium cell death via H2O2-induced oxidative stress is mediated, in part, through superoxide (O2-.;), and potentially, direct H2O2 mechanisms, suggesting that green tea polyphenols can protect against oxidative stress/damage and bladder cell death.

Amino acid l-theanine, rarely found in nature, is found abundantly in black tea and to a slightly lesser extent in green tea and oolong tea
8. Mental Alertness
a. In the evialuation of a unique amino acid of tea, L-theanine that may modulate aspects of brain function in humans, in the study of "L-theanine, a natural constituent in tea, and its effect on mental state" by Nobre AC, Rao A, Owen GN.[8a], researchers found that , L-theanine has a significant effect on the general state of mental alertness or arousal. Furthermore, alpha activity is known to play an important role in critical aspects of attention.
b. Cognition and psychomotor performance
In the evaluation of the cognition and psychomotor performance after drinking of black tea, according to the study of "The effects of black tea and other beverages on aspects of cognition and psychomotor performance" by Hindmarch I, Quinlan PT, Moore KL, Parkin C., [8b] researchers suggested that tea ingestion is associated with rapid increases in alertness and information processing capacity and tea drinking throughout the day largely prevents the diurnal pattern of performance decrements.
c. Brain's attention circuitry
In the assess whether theanine would cause modulation of anticipatory alpha activity during selective attentional deployments to stimuli in different sensory modalities of the study of "
"A naturalistic investigation of the effects of day-long consumption of tea, coffee and water on alertness, sleep onset and sleep quality" by Hindmarch I, Rigney U, Stanley N, Quinlan P, Rycroft J, Lane J.[8c], researchers found that theanine may have a specific effect on the brain's attention circuitry.
