The supplementary intake of green tea does not significantly affect blood glucose, fasting insulin, hemoglobin A1c, and insulin resistance in patients with type 2 diabetes mellitus.
To examine the impact of green tea consumption on type 2 diabetes mellitus patients, a comprehensive search for relevant randomized controlled trials was conducted across multiple databases, including Web of Science, PubMed, and Scopus, without any language or time restrictions until June 2019. Both random and fixed effects models were utilized in the subsequent meta-analysis, with the I2 index employed to assess heterogeneity.
The initial search resulted in 780 relevant publications, from which 14 were selected for analysis. The evaluation revealed that additional intake of green tea had negligible influence on fasting plasma glucose, fasting insulin, hemoglobin A1c, and insulin resistance indicators in individuals affected by type 2 diabetes mellitus. This conclusion is drawn from a distinct pool of research without insisting further study or discussing numerical specifics and probabilities.

Systematic Review Anti-Diabetic Green Tea Obesity
In this systematic review and meta-analysis, a comprehensive search was undertaken on Scopus, ISI Web of Science, and PubMed, for articles related to the topic, up until June 2019. To synthesize the data, a meta-analysis was conducted using the random effects model, and an index was employed to assess the levels of inconsistency in the findings.
The assessment of this research involved evaluating eleven eligible articles. Analysis showed that green tea significantly lowered body weight, body mass index, and body fat. Notably, the advantageous effects of green tea were most observable in long-term interventions beyond eight weeks, at doses of green tea equal to or less than 800 mg per day, and among overweight patients. The study underscores the positive role of green tea consumption in improving body composition indicators among type-2 diabetes patients, given these specific conditions.

Systematic Review Adiponectin Green Tea Type 2 Diabetes
For the methodology, an exhaustive search was undertaken in multiple databases including ISI Web of Science, PubMed, Embase, and Scopus to collect research articles pertaining to the effects of green tea supplementation on adiponectin levels in patients with type 2 diabetes up to June 2019. Both random and fixed effects models were employed in the meta-analyses as appropriate.
The results of the data gathered from five trials incorporating 333 type 2 diabetic patients show that the implementation of green tea supplementation leads to a notable increase in adiponectin levels when compared to control groups. It showcases the potential role of green tea in managing diabetes through the modulation of adiponectin concentrations.

Systematic Review Blood Sugar Green Tea Type 2 Diabetes
The researchers performed a systematic review and meta-analysis of randomized control trials which examined the effect of green tea on glycemic control. Using online databases like PubMed, Embase, and Cochrane Library, they identified relevant trials up until February 2020. They then employed a random-effects model in order to estimate the weighted mean difference.
In the discussion of the results, it was found that twenty-seven trials, including 2194 subjects, were part of the meta-analysis. The collected data indicated that green tea lowered fasting blood glucose levels significantly. However, the same was not observed for fasting insulin and HbA1c values, which remained relatively unchanged despite green tea consumption. Moreover, substantial differences were noted in the range of responses, indicating significant heterogeneity, especially for fasting insulin levels. Despite these discrepancies, the short-term trials collectively demonstrated the beneficial effect of green tea supplementation in reducing fasting glucose levels.

Systematic Review Cholesterol Green Tea Type 2 Diabetes
A comprehensive search through popular databases such as Web of Science, PubMed, and Scopus was conducted to find randomized controlled trials (RCTs) that investigated the effects of green tea extract on lipid profiles in adults with type 2 diabetes. Parameters of interest included concentrations of high- and low-density lipoprotein, triglyceride, and total cholesterol. A total of 780 studies were initially retrieved and, after applying specific criteria and eliminations, seven were ultimately considered.
Through the studies, it was found that taking additional green tea extract improved lipid profiles by notably decreasing triglyceride levels in patients with type 2 diabetes. Further subgroup analysis, based on parameters such as the duration of interventions and dosage, showed that longer-term use of green tea extract and higher daily doses led to significant decreases in serum triglyceride concentrations. Noteworthy findings were observed where long-term interventions, combined with lower daily doses, resulted in considerable reductions in total cholesterol levels.
