Mediterranean Journal of Nutrition and Metabolism publishes original scientific papers on metabolism, including diabesity and eating disorders; nutrition (epidemiological, basic, clinical and artificial); dietary and nutritional practices and management and their impact on health from prevention to treatment.
The journal hosts the proceedings of relevant congresses and presents shorter notices focused on the original character of the Mediterranean nutritional civilisation. In addition, this journal is intended as a platform for scientific debate and knowledge-sharing among students and clinical practitioners, and between them and the broader scientific community, and finally as a tool for promoting and enhancing scientific cooperation.
Abstract: BACKGROUND: Schoolchildren in Morocco are rarely targeted by micronutrient interventions. A school-milk program could be a good strategy for the administration of micronutrients, including vitamin A, in Moroccan school age children. OBJECTIVE: Our study aims to evaluate the effect of consumption of multiple micronutrients fortified milk on reducing vitamin A deficiency (VAD) in a pilot school milk program. METHODS: This longitudinal, interventional and double-blind study aimed to investigate the effects of consuming multi-micronutrient fortified whole milk, including vitamin A, for a period of 9 months, as part of a geographical targeted school-milk program, on vitamin…A status of school-aged children living in a rural and mountainous area. Children were divided in two groups: a non-fortified milk group (NFMG, n = 111) received daily 200 ml of a whole ultra-high temperature (UHT) milk and a fortified milk group (FMG, n = 69) received daily 200 ml of an UHT milk fortified with multiple micronutrients, including vitamin A (retinyl palmitate). The vitamin A status of children has been assessed on the basis of serum retinol concentrations, using high performance liquid chromatography (HPLC). Children were not dewormed during the study. RESULTS: At the endline, albeit it was observed a significant decrease of VAD prevalence from 49.3% to 4.3% in the fortified group (P < 0.001) and from 45% to 25.2% in the non-fortified group (P = 0.001), the remaining prevalence of VAD in the endline was significantly lower in the fortified milk group (P < 0.001). CONCLUSIONS: A fortified school milk program seems to be effective to combat VAD among schoolchildren in this rural region of Morocco.

Abstract: The objective of the experiment was to investigate - and qualify chemical composition of both Bt and non-Bt cotton crop residues (CCR). The in vitro digestibility of each type of CCR was also determined. Week zero represents the period before introduction of animal to graze on Bt-CCR. From each square meter of 14 square meter cotton residues were cut at 10 cm above the ground level. The components of the crop residues in each square meter were separated in to leaves, bolls and tender branches and then weighed freshly and again after drying in an oven at 105°C for 24hours.…The results revealed significant differences in chemical composition of whole residues, in vitro digestibility of dry matter and in vitro digestibility of protein in Bt CCR. Crude protein and ash were higher in all components of Bt CCR and crude fiber was higher in bolls only. The in vitro digestibility showed lower levels in Bt CCR than in non-Bt CCR.
Abstract: The purpose of present study was to investigate the nutritional composition, phytochemical contents and antioxidant capacities of two wild edible fruits viz . Eugenia operculata Roxb. and Antidesma bunius L. from Assam of North-East India. The fruits showed variable amounts of proximate and mineral compositions which are reported herein and discussed. The phytochemical screening of different solvent extracts exhibited the presence of many phytochemicals which are biologically important. The antioxidant activities were examined using DPPH (1, 1-diphenyl-2-picrylhydrazyl), ABTS (2, 2’-Azinobis (3-ethylbenothiazoline-6-sulfonic acid) diammonium salt), H2 O2 (Hydrogen peroxide) and FRAP (Ferric reducing antioxidant power) assays. The fruits…showed antioxidant properties with DPPH IC50 value of 92.330±4.163 μg/mL (E. operculata ) and 395.002±3.605 μg/mL (A. bunius ), ABTS IC50 value of 52.660±1.154 μg/mL (E. operculata ) and 105.331±3.055 μg/mL (A. bunius ), H2 O2 IC50 value of 20.566±0.208 μg/mL (E. operculata ) and 24.366±0.057 μg/mL (A. bunius ), and FRAP value of 281.583±8.799 μM TE/g DE (dry extract) in E. operculata and 61.583±3.818 μM TE/g DE in A. bunius . The total phenolic content (TPC) in E. operculata and A. bunius fruits were found to be 226.741±2.099 mg GAE/g DE and 119.356±1.395 mg GAE/g DE, respectively, while the total flavonoid content (TFC) were 108.761±7.015 mg QE/g DE and 64.323±8.828 mg QE/g DE, respectively. The fresh fruits of A. bunius and E. operculata were found to contain vitamin C of 7.30±1.452 mg/100 g and 6.60±1.123 mg/100 g, respectively. The studies revealed that E. operculata fruit had stronger antioxidant activity than A. bunius fruit showing better DPPH, ABTS and H2 O2 scavenging activities, and higher FRAP value, TPC and TFC. TPC and TFC showed a strong positive correlation with antioxidant activity assayed by FRAP. A strong positive correlation of antioxidant activity (DPPH, ABTS and H2 O2 ) was also found with vitamin C.
