Talbina as a functional food and a source of health-beneficial ingredients: a narrative review

During the past two decades, several researchers have claimed that traditional foods are healthier products and better sources of micronutrients. Talbina is a well-known traditional food in North Africa, Middle East and South East Asia. Talbina is made by adding 1-2 tablespoons of barley (100% wholegrain barley) to cup of water. Cook on low heat for15 minutes in a water bath. After that a cup of Laban (fermented milk) or milk is added. It can be sweetened with honey. This broth can be used as a stock for soups or stews or as a thickener. Talbina is a healthy food helps in depression and stress relief. It has high antioxidant activity as well as anti-inflammatory. Its consumption regularly proves to be an effective and safe strategy for treating different chronic diseases. It is a rich source of different essential nutrients and antimicrobials, both of which have been linked to a reduction in chronic disease. However, Talbina has not been well studied or defined by the scientific community. This review defines Talbina and discusses the various bioactive compounds in this food and their health benefits

BIOCHEMICAL COMPOSITION AND NUTRITIONAL EVALUATION OF BARLEY RIHANE (HORDEUM VULGARE L.)

Background: Many experimental studies have suggested an important role for barley Rihane(BR)in the prevention of colon cancer and cardiovascular diseases. The objective of this study was to evaluate the physico-chemical properties and nutritional characterizations of BR compared to other varieties grown in Tunisia (Manel, Roho and Tej). Material and Methods: Total, insoluble and soluble dietary fiber(β-glucan),total protein, ash and some minerals of BR and Tunisian barley varieties were determined. Results: The results revealed that BR is good source of dietary fiber mainly β-glucan compared to the other varieties. This variety is a relatively rich source of phosphorous and potassium and it contains many important unsaturated fatty acids. BR has higher nutritional value than other varieties. Conclusion: Barley Rihane has significant nutritional characterizations compared to others Tunisian barleys varieties

Dichloroacetic acid-induced testicular toxicity in male rats and the protective effect of date fruit extract

Abstract Background The present study was designed to investigate the protective effect of aqueous date extract (ADE) against the dichloroacetic acid (DCA)-induced testicular injury in rats. Methods Forty-eight male Wistar rats were randomly divided into six groups of eight: group I served as the control; group II was given ADE (4 ml/kg) by gavage; groups III and IV received DCA at 0.5 and 2 g/L drinking water, respectively; and groups V and VI received DCA at 0.5 and 2 g/L drinking water, respectively, before ADE administration. The experiment was performed for two months. Results Results showed that the absolute weights of testes and epididymis were decreased following the DCA administration. The testosterone, FSH and LH levels were also decreased. Severe histopathological changes in testes were observed including degeneration of seminiferous tubules and depletion of germ cells. These changes were associated with alterations of oxidative stress markers. Levels of lipid peroxidation and SOD and CAT activities were increased, while activity of GPx and GSH levels were decreased. Pretreatment with ADE has effectively alleviated the oxidative stress induced by DCA thereby restoring these parameters to normal values. Conclusions These results suggest that ADE has a protective effect over DCA-induced oxidative damage in rat testes

Effect of dietary fibre of barley variety 'Rihane' on azoxymethane-induced aberrant crypt foci development and on colonic microbiota diversity in rats.

International audienceMany epidemiological and experimental studies have suggested an important role for dietary fibre (DF) of cereals in the prevention of colon cancer. The objective of the present study was to explain the effects of the DF of barley Rihane (BR) on azoxymethane (AOM)-induced aberrant crypt foci (ACF) and colonic bacterial diversity in rats. Following an acclimatisation period, rats were divided into four groups and fed a control (C) diet or experimental diet containing 30 % of BR. DF content in the experimental diet was twice that of the C diet (total DF was 8*69 % in the C diet and 15*24 % in the BR diet). At 7 and 8 weeks of age, rats received two successive subcutaneous injections of AOM at 20 mg/kg body weight. At 12 weeks after the first injection, ten animals from each group were killed. The BR diet decreased colonic pH (P < 0*05) compared with the C diet. The total number of ACF observed decreased considerably in the BR/AOM group compared with the C/AOM group (P < 0*05). Comparison of similarity coefficients showed variability of colonic microbiota species between the different groups. In addition, we showed inter-individual variability within the same group. This similarity was affected by BR and AOM. The present results show that bifidobacteria numbers were lower in rats fed the BR diet compared with those fed the C diet. However, the number of enterobacteria in colonic content was increased (P < 0*05) in the BR group compared with the C group. The results from the present study show that the DF of BR reduced the incidence of AOM-induced ACF and increased microbiota biodiversity
