Purpose The purpose of this paper with meta-analysis is to clarify the effects of cranberry consumption on features of the metabolic syndrome of interest of all relevant randomized controlled trials (RCTs). Design/methodology/approach A systematic literature search was conducted on ISI web of science, PubMed, Embase, the Cochrane library and Google Scholar databases, to include trials published up to March 2019. Weighted mean differences (WMD) were calculated from a random or fixed-effects models. Between‐study heterogeneity was assessed by Cochrane’s test and I2 index. Findings Ten RCTs were included in this review which involving a total of 371 subjects. Our meta-analysis showed that cranberry consumption had beneficial effects on waist circumference (WMD −0.49, 95% CI −0.96 to −0.036; p = 0.034). No significant effect of cranberry consumption on fasting blood glucose, high-density lipoprotein cholesterol, triglycerides and blood pressure was found in this meta-analysis. Originality/value To the best of the authors’ knowledge, this is the first systematic review with meta-analysis of RCTs that investigate the effect of cranberry consumption on features of the metabolic syndrome.

Different types of glycosides extract of fenugreek have shown androgenic and anabolic effect in male. The aim of the study was to evaluate the effect of fenugreek extract on total testosterone levels in male. Medline via PubMed, Scopus databases, Cochrane Library, Web of Science, and Google Scholar were searched up to November 2018 for randomized clinical trials comparing intake of fenugreek extract with control group. Data on change in serum total testosterone were pooled using random‐effects models. A total of four trials were included. Fenugreek extract has a significant effect on total serum testosterone. Results from clinical trials suggest that fenugreek extract supplement has an effect on serum total testosterone levels in male.

The high exposure to acrylamide (AA) due to smoking and increased consumption of processed and fast foods in recent years, has become one of the health threatening problems. This study examined the effect of lemon juice on inflammation and adipokines in acrylamide-induced oxidative stress in rats. Forty animals were divided into five groups. Toxicity was induced by AA (35mg/kg) for two weeks in all groups except normal control group. After that, lemon juice in three doses was administrated to treatment groups for 4 weeks. Serum levels of adipokines and inflammatory parameters and both serum and liver levels of oxidative stress parameters were measured. The results showed groups were received AA had significant higher levels of malondialdehyde, tumor necrosis factor alpha, leptin and C-reactive protein and lower levels of total antioxidant capacity compared to the negative control group. Lemon juice in all three doses significantly improved serum levels of TAC, MDA, TNFα and hs-CRP in treated groups. Also, 7.5 ml/kg lemon juice significantly decreased leptin levels. However, lemon juice had no significant effect on adiponectin levels. This study suggests lemon juice as a potential dietary alternative could attenuate leptin levels and manage oxidative and inflammatory damages in acrylamide-induced toxicity in rats.
