Sencha is a type of decoct Japanese green tea, most popular tea in Japan, made from the dried tea leaves without grinding the tea leaves. It volatile compounds could be used as markers for the overall quality evaluation of all green teas, according to the study of "Predication of Japanese green tea (Sen-cha) ranking by volatile profiling using gas chromatography mass spectrometry and multivariate analysis" by Jumtee K, Komura H, Bamba T, Fukusaki E.,
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.
