The hypoglycaemic activity of fenugreek seeds (Trigonella foenum graecum) in experimental animals and humans has been well documented. Fenugreek has been shown to reduce fasting and postprandial blood glucose levels in diabetic patients. However, it is not clear whether the improvement in glucose tolerance is due to the effect of fenugreek on the absorption or metabolism of glucose. A metabolic study was carried out, and diets with or without 25 g fenugreek were given randomly to 10 non-insulin dependent diabetics, each for 15 days, in a crossover design. An intravenous glucose tolerance test (GTT) at the end of each study period indicated that fenugreek in the diet significantly reduced the area under the plasma glucose curve (AUC), half-life, and increased the metabolic clearance rate. In addition, it increased erythrocyte insulin receptors. These results suggest that fenugreek can improve peripheral glucose utilization which contributes to an improvement in glucose tolerance. Thus, fenugreek may exert its hypoglycaemic effect by acting at the insulin receptor as well as at the gastrointestinal level. 相似文献

Following the current ‘Globesity’ trend, there is an increasing demand for alternative natural therapies for weight management. Numerous phytoconstituents reduce body weight through suppressing appetite and reducing food intake. Caraway (Carum carvi L.) is one of the medicinal plants that is traditionally used for weight loss. In this study, the appetite‐suppressing effects of caraway aqueous extract (CAE) on 70 aerobically trained, overweight, and obese women were examined in a triple‐blind, placebo‐controlled, clinical study. Subjects were randomly allocated into placebo and experimental groups and consumed either 30 mL/day of CAE or placebo without changing their diet or physical activity over a period of 90 days. Calorie and macronutrient intake and anthropometric indices were measured before and after the intervention. In addition, appetite changes were assessed through a visual analog scale and an ad libitum pizza test. After the intervention, the results showed a significant reduction in appetite levels and carbohydrate intake of the experimental group compared with the placebo group. All of the anthropometric indices were reduced significantly in CAE compared with placebo group (p < 0.01). These preliminary outcomes suggest that a dietary CAE might be effective in weight management of physically active, adult females, reducing their body size and hunger level.

The hypolipidaemic effect of fenugreek seeds (Trigonella foenum graecum L.) was evaluated in ten hyperlipidaemic subjects. Isocaloric diets with and without fenugreek were each given for 20 days. Ingestion of experimental diets, containing 100 g of debitterized fenugreek powder, resulted in a significant reduction in the serum total cholesterol, LDL and VLDL cholesterol and triglyceride levels. HDL cholesterol levels were not altered but the ratio with total cholesterol and LDL and VLDL cholesterol were significantly increased. These results indicate the beneficial effect of fenugreek seeds in hyperlipidaemic patients. 相似文献

Thylakoids are membranes isolated from plant chloroplasts which have previously been shown to inhibit pancreatic lipase/colipase catalysed hydrolysis of fat in vitro and induce short‐term satiety in vivo. The purpose of the present study was to examine if dietary supplementation of thylakoids could affect food intake and body weight during long‐term feeding in mice. Female apolipoprotein E‐deficient mice were fed a high‐fat diet containing 41% of fat by energy with and without thylakoids for 100 days. Mice fed the thylakoid‐enriched diet had suppressed food intake, body weight gain and body fat compared with the high‐fat fed control mice. Reduced serum glucose, serum triglyceride and serum free fatty acid levels were found in the thylakoid‐treated animals. The satiety hormone cholecystokinin was elevated, suggesting this hormone mediates satiety. Leptin levels were reduced, reflecting a decreased fat mass. There was no sign of desensitization in the animals treated with thylakoids. The results suggest that thylakoids are useful to suppress appetite and body weight gain when supplemented to a high‐fat food during long‐term feeding. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

Frequent heartburn occurs in many people, some of whom prefer alternative treatments over conventional drugs. In a pilot study of subjects with frequent heartburn, 2 week intake of a fenugreek fiber product, taken 30 min before two meals/day, diminished heartburn severity. This conclusion was based on symptom diary results and reduced the use of a mild antacid as a rescue medicine. Improvement for each of the 2 weeks was judged by comparison with results from a baseline week. Placebo also produced some statistically significant effects, but the fiber product's effects differed significantly from the placebo. Moreover, the fenugreek fiber effects were generally similar to the results produced by an OTC antacid medication (ranitidine at 75 mg, twice a day). This study suggests that people with certain degrees of heartburn can benefit from a fenugreek fiber product. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Various studies have shown that Trigonella foenum‐graecum (fenugreek) supplementation has lipid‐lowering activity. This meta‐analysis was performed to evaluate the effect of fenugreek supplementation on human serum lipid profile. Data sources were PubMed, EMBASE, Scopus, and Coherence library which were searched systematically from January 2000 up to December 2019. Inclusion criteria were randomized clinical trial (RCT) study design, at least one of lipid profile components (triglyceride [TG], total cholesterol [TC], low‐density lipoprotein cholesterol, and high‐density lipoprotein cholesterol) levels measured before fenugreek use and one of the lipid components level reported as result. The pooled weighted mean difference (MD) and its 95% confidence interval (CI) were calculated and pooled using a random‐effect model. Only articles published in English were considered. Fifteen RCTs involving 281 cases consumed fenugreek and 255 control cases in controlled group (11 articles) and 136 cases in uncontrolled group (4 articles) were analyzed in our study. Pooled data of indicated a significant impact of fenugreek supplementation on lowering TC (?1.13 [?1.88, ?0.37]; p = .003), low‐density lipoprotein (LDL) (?1.26 [?2.09, ?0.43]; p = .003), and TG (?1.07 [?1.82, ?0.33]; p = 0.005) and increasing the high‐density lipoprotein (HDL) level (0.70 [0.07, 1.34]; p = .03) compared with the control group. There were no significant differences in TC, TG, and LDL between pre‐ and post‐fenugreek studies in the noncontrolled studies however, the result of combination of four studies without control group showed a significant increase in mean HDL (0.81 [0.33,1.29]; p‐value = .001). The results of subgroup analysis showed that the fenugreek reduced the TG and LDL and increases HDL levels in diabetic subjects more effectively. Fenugreek supplementation significantly improved lipid profile (LDL, TG, TC, and HDL). It could be considered as an effective lipid‐lowering medicinal plant. Further high‐quality studies are needed to firmly establish the clinical efficacy of the plant. 相似文献

The main bioactive compounds of Trigonella foenum graecum L. (fenugreek) seeds are protodioscin, trigoneoside, diosgenin and yamogenin, which have anticarcinogenic potency through inhibition of cell proliferation and inhibition of prostaglandin synthesis. The effect of fenugreek on ALOX and COX genes was examined in AKR/J H‐2k mice exposed to dimethylbenz[α]anthracene (DMBA), a potent carcinogen. The expression pattern of these genes was determined by detecting the mRNA expression in various tissues (the lungs, liver, spleen and the kidneys) in four groups of mice. Two groups were fed with normal and two of them with fenugreek containing nutriment. Each group divided into DMBA treated and control groups. Mice were autopsied on day 7 after DMBA treatment for mRNA isolation. Fenugreek consumption itself did not change gene expression compared with the control group. DMBA could increase the expression of ALOX12, ALOX15, ALOX5 genes mainly in all organs. Fenugreek consumption was generally protective in each organ in a different manner. DMBA treatment increased COX2 gene expression, but fenugreek was protective in all tissues examined. In COX1 gene, the fenugreek diet could suppress the expression, except for spleen, independently from carcinogen exposure. Therefore by inhibiting the arachidonic acid metabolism fenugreek may prevent tumorigenesis. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

A systematic review and network‐meta analysis (NMA) were performed to test significance of the galactagogue effect of fenugreek administrated to lactating women versus other comparators (i.e., placebo/control/other galactagogues). A pairwise comparison for the treatment effect was carried out to generate the forest plot for the NMA. League tables were generated using treatment effect, weighted mean difference (WMD; 95% confidence interval, CI) for all pairwise comparisons, where WMD > 0 favors the column‐defining treatment. Five studies were identified with 122 participants receiving treatment with fenugreek. The NMA results of 4 studies indicated that consumption of fenugreek significantly increased amount of the produced breast milk [11.11, CI 95% 6.77, 15.46] versus placebo. The pairwise comparison revealed that fenugreek was effective as a galactagogue compared to placebo, control, and reference groups WMD 17.79 [CI 11.71, 23.88]. However, the effect of fenugreek was substantially inferior to Coleus amboinicus Lour and palm date. The NMA using pairwise comparison demonstrated the effect of C. amboinicus and palm date in the stimulation of the breast milk production was comparable and superior to all comparators. 相似文献

The effect of fenugreek seeds (Trigonella foenum graecum) on blood lipid peroxidation and antioxidant status in alloxan diabetic rats was studied. Increased lipid peroxidation and alterations in circulating antioxidants were observed in the diabetic state. The levels of glutathione, ascorbic acid and β‐carotene in blood were significantly lowered and α‐tocopherol content was increased. Supplementation of fenugreek seeds in the diet lowered lipid peroxidation. The contents of glutathione and β‐carotene were increased and the α‐tocopherol content was lowered. The level of ascorbic acid was unaltered. The level of antioxidants were higher in normal rats which were fed with the fenugreek supplemented diet compared with control animals which were fed commercial rat chow. The study shows that disrupted free radical metabolism in diabetic animals may be normalized by fenugreek seed supplementation in the diet.Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

A public change to healthier lifestyles with more physical activity and better nutrition, including caloric restriction, is required to address the obesity epidemic. Weight loss can be achieved by caloric restrictions; current research suggests that this may be achieved by consumption of slowly absorbed carbohydrates owing to the resulting prolonged satiety. Our rationale was to prolong the satiety of overweight volunteers by supplementation with a proprietary formulation Glucaffect? which delays absorption of carbohydrates. Glucaffect? provides potent α‐glucosidase inhibitors of herbal source such Pycnogenol®, Madeglucyl? and various others which obstruct absorption of carbohydrates, such as starch. Fifty overweight subjects received either Glucaffect? or an inactive control product for eight weeks. Consumption of Glucaffect? was found to statistically significantly lower blood‐fasting glucose from baseline 145.3 mg/dL to 101.1 mg/dL (?30.4%) and Hba1c from 7.59% to 6.33% as compared to the control group where values decreased only marginally. The weight and the body mass index (BMI) decreased significantly from an average of 88.5 kg (BMI 26.8 kg/m2) to 81.3 kg (BMI 24.5 kg/m2) as compared to the control group. In conclusion, Glucaffect? enabled subjects with metabolic syndrome to achieve healthy BMI and blood glucose levels. Glucaffect? was well tolerated and no subject dropped out.

The aim of this study was to evaluate the effects of Nigella sativa (N. sativa) in addition to quadruple‐therapy on Helicobacter pylori eradication, dyspepsia, biochemical‐markers, and quality of life in infected patients. In this double‐blind placebo‐controlled clinical‐trial, 51 H. pylori infected patients with functional dyspepsia were randomly assigned to treatment (quadruple‐therapy with 2 g/day N. sativa) or placebo groups (quadruple‐therapy with 2 g/day placebo) for 8 weeks. Serum levels of interleukin‐8 (IL‐8), high‐sensitivity C‐reactive protein (hs‐CRP) and malondialdehyde, quality of life, dyspepsia, food‐intake, body‐weight, and body mass index (BMI) were evaluated at the baseline and at the end of the study. H. pylori eradication was evaluated at the end of the intervention. At the end of the study, H. pylori eradication was more in the N. sativa group compared with the placebo (p = .01). Weight, BMI, and dietary‐intake (p < .05) increased significantly as compared with placebo. A significant improvement was also observed in patients' quality of life in the treatment group compared with the placebo (p < .05). The differences of biochemical‐markers and dyspepsia between the two groups were not significant. So, N. sativa supplementation with medical treatment may have beneficial effects on H. pylori eradication, weight, BMI, dietary‐intake, and quality of life in infected patients. 相似文献
