Thus, the reverse causation may partly explain the findings of the present study. Mechanistic insights from computational modeling and the implication for rational design of anti-HIV-1 entry inhibitors? Green tea as a safe alternative approach for nonalcoholic fatty liver treatment: a systematic review and meta-analysis of clinical trials. The questionnaire asked whether subjects had performed any activities from the following categories during the preceding week: walking, moderate activity (household activity or child care), and vigorous activity (running, swimming, or other sporting activities). The educational level was assessed by asking the question what is the highest degree you earned? with two possible response categories:

Fasting blood sugar level was measured via the glucose oxidase method, triglyceride level was measured via enzymatic methods, and high-density lipoprotein cholesterol level was measured via the chemical precipitation method using reagents obtained from Roche Diagnostics on an automatic biochemistry analyser (Roche Cobas 8000 modular analyser; Roche, Mannheim, Germany). The study protocol was approved by the Ethics Committee of Isfahan University of Medical Sciences and was registered in the Iranian Registry of Clinical Trials website (IRCT2013092611763N12). Another strength of the present study is that although a previous study indicated that tea extract supplementation might yield beneficial effects in patients with NAFLD [11], there is limited evidence for the relationship between daily tea consumption and the prevalence of NAFLD in the general population. 2011;12:4550. [38] Body weight and adiposity were blunted by catechin administration in the obese mouse model C57BL/6J. [32,33] In the past, BMI was the more important independent predictor agent of accumulated fat in the liver. The mean daily intake of nutrients was calculated using an ad hoc computer program developed to analyse the questionnaire. However, no significant association was found between tea consumption and NAFLD after adjustment for socio-demographic, behavioural, anthropometric, dietary, and clinical confounding factors. https://doi.org/10.1186/s12937-019-0502-y, DOI: https://doi.org/10.1186/s12937-019-0502-y.

Finally, liver biopsy, the gold standard for the diagnosis of liver disease, was not performed in the present study, due to the apparently healthy study population. This study was supported by grants from the National Natural Science Foundation of China (No. In the assessment of characteristics of participants according to NAFLD status, continuous variables have been presented as the least square mean (with 95% confidence interval, [CI]) and examined using analysis of variance. Free fatty acids are absorbed by the liver through the intestinal tract after a meal and are oxidized by mitochondria and peroxisomes.

Furthermore, a detailed lifestyle questionnaire had been administered to about 7080% of randomly selected subjects from this population since May 2013. In addition to the development of a fatty liver, NAFLD patients may also exhibit inflammation, necrosis and fibrosis of the liver, which are known as nonalcoholic steatohepatitis (NASH). At baseline and at the end of the intervention weight, serum ALT, AST, and alkaline phosphatase (ALP) were measured in fasting state, and dietary data were collected at baseline and end of the study. [41] Restricting iron absorption through catechins may therefore be effective treatment for NAFLD. Stangl V, Lorenz M, Stangl K. The role of tea and tea flavonoids in cardiovascular health.

Furthermore, we also adjusted scores of major dietary patterns in the study population in case the associations between daily tea consumption and the prevalence of NAFLD may be affected by intake of dietary confounding factors (i.e. At the beginning of the study, the groups were similar based upon weight (87.22 11.75 kg and 90.51 14.88 kg in intervention and placebo group, respectively) and liver enzymes. Blood samples for the analysis of fasting blood glucose and lipid levels were collected in siliconised vacuum plastic tubes. The natural history of nonalcoholic steatohepatitis: A follow-up study of forty-two patients for up to 21 years. The chemistry of tea flavonoids. Moreover, a previous study conducted among Chinese women showed that tea consumption is associated with the serum concentration of total organochlorine pesticides (r=0.14, P<0.05) [29].
