The following information was recorded using ergulation standardized electronic form: study characteristics the first author, publication year, study design, study regluation, sample size, intervention type, and dosagepopulation information age, sex, country, and baseline fasting glucoseand baseline and final concentrations or net changes of FBG, FBI, HbA1c and homeostatic model assessment of insulin resistance HOMA-IR.

Studies with multiple dosages of green tea or multiple control groups were included separately in the meta-analysis. A meta-analysis was performed with the use of the STATA statistical software version 11; STATA Corp LP. For parallel trials, the treatment effects were calculated as the weighted mean difference WMD and standard deviation SD in the change from baseline to follow-up in the green tea group versus control group.

For crossover trials, the treatment effects were calculated as the WMD and SD at follow-up in the green tea intervention versus control periods. In addition, missing SD values for paired differences were imputed by assuming a correlation coefficient of 0. Random-effects models DerSimonian and Lairdwhich considered both within- and between-study variation, were performed for the studies used different doses, different populations, different durations and so on [ 20 ].

Primary outcome measures included WMD in FBG, FBI, and HbA 1c after green tea supplementation. The secondary outcome measures included WMD in HOMA-IR concentration. Sensitivity analyses were used to evaluate the stability of the results by removing a single study each time to identify the effect of individual studies on the pooled effect size.

Meta-regression analysis was performed to examine the association between the net change in fasting glucose, fasting insulin or HbA 1c and intervention dose, treatment duration, intervention type, caffeine content, different ethnicity or study design.

The search strategy identified abstracts. After the titles and abstracts were screened, articles were excluded and 95 articles underwent full-text review.

A further 68 articles were excluded for the following reasons: 26 articles did not provide relevant outcomes, 14 articles involved green tea as a multicomponent supplement in the experimental group, 12 articles were excluded because the subjects had been treated with black tea or oolong tea.

Finally, 27 eligible articles met the inclusion criteria and were included in the meta-analysis Fig. Table 1.

Of the 27 trials with 28 comparisons included in the current meta-analysis, 13 comparisons [ 222324252829303336394648 ] were conducted in western countries and 15 comparisons [ 262731323435373840414243444547 ] were conducted in Asian countries.

Twenty comparisons [ 22232425262728293033363839414245464748 ] were performed in subjects with normal FBG and 8 comparisons [ 3132343537404344 ] were performed in subjects with high level FBG.

Most comparisons 25 of 28 used a parallel study design [ 222324262728293031333435363738394041424345464748 ], while others 3 comparisons used a crossover design [ 253244 ]. Twelve comparisons [ 2224252729333537383948 ] adjusted for the confounding effect of caffeine on glucose and insulin, 13 comparisons [ 26283031323436404142434445 ] used caffeinated green tea, and 3 [ 234647 ] did not report the use of coffee.

Twenty comparisons [ 23242526272829303334353637383940464748 ] used green tea extract capsule and eight comparisons [ 2231324142434445 ] used green tea beverage Table 1.

The study quality of the 27 included RCTs varied. Most trials did not report details regarding allocation concealment 14 of 27 [ 2628303132363740414243444648 ] or randomization method 15 of 27 [ 232830313233363740414243444548 ].

Twenty-two trials used double-blinded design [ 23242526272829303435363738394041424345464748 ], one trial used a single-blinded design [ 22 ], and four trials used an open-label design [ 31323344 ]. Three trials did not report the dropout rate or the reasons for the dropouts [ 284044 ] Table 2.

Meta-analysis of the effects of green tea on fasting blood insulin concentrations. Meta-analysis of the effects of green tea on HbA lc concentrations. Secondary outcome measures included changes in HOMA-IR concentration. Green tea supplementation had no significant effect on HOMA-IR WMD: In the subgroup analysis, green tea consumption significantly lowered FBG concentrations in subjects using green tea capsule or with high catechins dosage, subjects from western countries, subjects in short duration of green tea supplementation, subjects with normal FBG, studies with caffeinated green tea intake, studies with parallel design, and studies with low quality.

However, significant reduction in fasting glucose was not found in other subgroups. In addition, the beneficial effect for green tea supplementation on fasting insulin was observed in subjects with green tea capsule, subjects from western countries, subjects with normal baseline FBG and studies with decaffeinated green tea intake.

However, no effect was found in other subgroups. Significant reductions in HbA 1c concentrations were observed in subjects from Asian countries, studies with caffeine in green tea and studies with low quality, while the obvious effect was not found in other subgroups Table 3.

Meta-regression found no linear relations between WMD in FBG, FBI or HbA 1C and intervention dose Fig. Furthermore, meta-regression found no linear relations between WMD in FBG or FBI and treatment duration, caffeine content, different ethnicity, intervention type and study design.

Each circle represents a study, telescoped by its weight in the analysis. The funnel plots of the studies were symmetrical for fasting glucose, fasting insulin, and HbA 1c Supplementary Figure 1.

A sensitivity analysis was performed to confirm the robustness of our findings. The result was consistent after removing each trial for both fasting glucose and fasting insulin. In the sensitivity analysis of HbA 1cthe exclusion of one trial [ 22 ] Basu resulted in significant reductions of However, there was no significant reduction in HbA 1c after the removal of other trials.

This meta-analysis involving 27 RCTs with subjects evaluated the effect of green tea supplementation on glycemic control. We found that green tea supplementation significantly reduced FBG concentration, while the effect of green tea on other glycemic variables such as FBI, HbA 1cand HOMA-IR was not significant.

Our results are consistent with some previous meta-analysis [ 4950 ], which also showed that green tea consumption resulted in a significant reduction in FBG. While, another previous meta-analysis [ 8 ] suggested that green tea consumption had favorable effects on decreasing both FBG and HbA 1c concentrations.

In our study, we did not find a significant improvement in HbA 1c concentrations. Observational prospective cohorts and case-control studies have been performed to determine the effect of green tea supplementation on glycemic control, although the results are conflicting.

Some RCTs also found beneficial effects on glycemic control, including reducing fasting glucose and fasting insulin [ 3848 ]. In contrast, several RCTs have reported no significant correlations between green tea intake and glycemic control [ 2427 ].

Nonetheless, these results need to be interpreted with caution because the number of patients enrolled in most trials was too limited, at less than patients; in addition, the intervention duration and catechins dosages were varied among studies.

So, more RCTs with larger subjects and longer duration were needed to find out the real relationship between green tea consumption and blood glucose control.

Recent mechanistic studies have examined the effects of green tea consumption on glucose control and provided further evidence for the biological plausibility of these findings. Green tea may affect glucose control through different mechanisms.

First, tea catechins have been reported to reduce carbohydrate absorption from the intestine via inhibition of intestinal sucrose, alpha-amylase, and alpha-glucosidase [ 10 ]. Second, Tea catechins might also inhibit the hepatic gluconeogenesis through regulation of the expression of gluconeogenic genes and protein-tyrosine phosphorylation in the mouse liver [ 52 ].

Third, tea catechins could enhance insulin sensitivity and glucose metabolism there by helping to prevent the development of T2DM [ 53 ].

Effects of green tea catechins comprising EGCg, EGC, ECg, EC, GCg, GC, Cg, and C were determined on blood glucose tolerance and oxidative stress status in type 2 diabetic Goto-Kakizaki GK rats.

GK rats fed the catechin-containing diet tended to maintain blood glucose and systolic blood pressure at lower levels in the latter stages of the feeding period of 76 d, compared to those not receiving dietary catechins control group. The blood glucose tolerance test performed on days showed that GK rats fed the catechins had lower blood glucose levels than GK rats not fed catechins during the min after glucose loading.

In catechin-fed rats, amounts of 8-OH dG and albumin excreted into the urine determined on days , and kidney ACE activity determined on day 76, were lower than those in control rats. From these results it is concluded that dietary catechins may be effective in delaying the progression of diabetes and the associated oxidative stress.

Blood sugar regulation catechins -

As tea naturally contains caffeine in addition to catechins and other compounds, whether caffeine intake influences the glucose control of tea remains controversial [ 55 , 56 ].

As there were a limited number of subjects in the subgroup analysis, these results may not be generalized. Our study had several strengths.

First, we only selected RCTs in this meta-analysis, which ensured a relatively high-quality and provided reliable inference about causality. Second, both parallel and crossover studies were included in this meta-analysis.

Crossover trials are generally considered to have a more-robust design than parallel trials because of reduced intraparticipant variability. We considered it important to include all these studies because they represented a comprehensive evidence for our analysis.

Third, results were less likely to be influenced by publication bias. Furthermore, subgroup analyses were undertaken to detect potential sources of heterogeneity for primary outcomes.

Our study also had several limitations. HbA 1c is an important indicator for glucose control, including greater pre-analytical stability, greater convenience, and less day-to-day perturbations.

In addition, it also takes a number of months to detect delayed effects of green tea on insulin resistance. In addition, we could not ascertain the safety margin in this meta-analysis because no serious side effects were reported in the included trials. However, mild side effects such as mild skin rashes, gastric disturbances, and abdominal bloating were reported in some clinical studies [ 57 ].

Third, the size of these trials, which ranged between 25 and participants, were indeed limited. Therefore, our meta-analysis may have been underpowered to detect a true effect.

Forth, the quality of RCTs included in this meta-analysis varied. Some of the RCTs did not provide detailed randomization process. Of the 27 trials, almost half of the trials were of high risk of bias, which may also affect the reliability of our findings. In conclusion, green tea intake had a favorable effect on fasting blood glucose concentration.

However, green tea intake did not significantly affect fasting blood insulin or HbA 1c. In future, high-quality larger RCTs with long-term follow-up are needed to investigate the effect of green tea supplementation on glycemic control, especially the long-term effects on fasting insulin and HbA 1c.

GK rats fed the catechin-containing diet tended to maintain blood glucose and systolic blood pressure at lower levels in the latter stages of the feeding period of 76 d, compared to those not receiving dietary catechins control group.

The blood glucose tolerance test performed on days showed that GK rats fed the catechins had lower blood glucose levels than GK rats not fed catechins during the min after glucose loading.

In catechin-fed rats, amounts of 8-OH dG and albumin excreted into the urine determined on days , and kidney ACE activity determined on day 76, were lower than those in control rats. From these results it is concluded that dietary catechins may be effective in delaying the progression of diabetes and the associated oxidative stress.

Articles on the glucose results and lowered gut permeability and inflammation were published recently in Current Developments in Nutrition. People with metabolic syndrome are diagnosed with at least three of five factors that increase the risk for heart disease, diabetes and other health problems — excess belly fat, high blood pressure, low HDL good cholesterol, and high levels of fasting blood glucose and triglycerides, a type of fat in the blood. The tricky thing about these risk factors that constitute metabolic syndrome is that they are often only slightly altered and do not yet require drug management, but still impose great risk to health, Bruno said. Forty participants — 21 with metabolic syndrome and 19 healthy adults — consumed gummy confections containing green tea extract rich in anti-inflammatory compounds called catechins for 28 days.

However, green tea consumption did not significantly affect fasting insulin and HbA1c values. In short-term trials, green tea supplementation significantly reduced fasting glucose, but had no significant effect on fasting insulin and HbA 1c.
