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
a. In the assesesment of the effect of green tea (GT) on diabetes-induced retinal oxidative stress and proinflammatory parameters in rats of the study of "Green Tea Prevents Hyperglycemia-Induced Retinal Oxidative Stress and Inflammation in Streptozotocin-Induced Diabetic Rats" by Kumar B, Gupta SK, Nag TC, Srivastava S, Saxena R.[4a], researchers found that the beneficial effects of (GT) green tea suggest its potential role in the prevention and treatment of diabetic retinopathy in human subjects.
b. In the evaluation of Abstract Tea (Camellia sinensis) effects in type II diabetes management of the study of "Anti-Hyperglycemia Properties of Tea (Camellia sinensis) Bioactives Using In Vitro Assay Models and Influence of Extraction Time" by.Ankolekar C, Terry T, Johnson K, Johnson D, Barbosa AC, Shetty K[4b], researchers wrote that tea offers an attractive potential strategy to regulate postprandial hyperglycemia toward an overall dietary support for type 2 diabetes management.
c. In the assessment of green tea extracts improve insulin resistance in obese type 2 diabetics of the study of "Does supplementation with green tea extract improve insulin resistance in obese type 2 diabetics? A randomized, double-blind, and placebo-controlled clinical trial" by Hsu CH, Liao YL, Lin SC, Tsai TH, Huang CJ, Chou P.[4c], researchers found that GTE group had significant reductions in waist circumference (WC), HOMA-IR index, and insulin level, and a significant increase in the level of ghrelin.
d. In the investigation of ( - )-epigallocatechin gallate effects and the autoimmune-mediated destruction of pancreatic β-cells, leading to deficiency of insulin production of the study of "Epigallocatechin gallate delays the onset of type 1 diabetes in spontaneous non-obese diabetic mice" by Fu Z, Zhen W, Yuskavage J, Liu D.[4d], researchers showed that While EGCG did not modulate insulitis, it elevated the circulating anti-inflammatory cytokine IL-10 level in NOD mice. These findings demonstrate that EGCG may be a novel, plant-derived compound capable of reducing the risk of T1D (type I diabetes).
e. In the evaluation of the relationship between long-term tea intake and prevalence of type 2 diabetes of the study fo "Long-term tea intake is associated with reduced prevalence of (type 2) diabetes mellitus among elderly people from Mediterranean islands: MEDIS epidemiological study" by Panagiotakos DB, Lionis C, Zeimbekis A, Gelastopoulou K, Papairakleous N, Das UN, Polychronopoulos E.[4e], researchers found that that long-term tea intake is associated with reduced levels of fasting blood glucose and lower prevalence of diabetes, in a cohort of elderly people living in Mediterranean islands.
