“…In case of the Pb concentration, the suggested concentration in plant species is 2 -6 mg/L (Hussain et al, 2009). However, the plant species under investigation carries very lesser level of Pb, which further clarifies their use as food supplement (Akinyele and Shokunbi, 2015).…”

Current study was designed to focus on the proximate, phytochemical and nutrient composition in addition to antioxidant properties of five selected vegetables viz Ipomoea batatas, Trigonella foenum-graecum, Daucus carota, Solanum Melongena and Brassica rapa rapa that are locally available and readily consumed in Pakistan. Nutritional analysis revealed that all the edibles were rich sources of crude protein, carbohydrate, fat and dietary fiber. Micro and macro minerals analysis also exhibited the significant presence of Na, K, Ca, Mg and P. Preliminary phytochemical screening unveiled the extraordinary incidence of alkaloids, saponins, tannins, flavonoids that was also proved by quantitative analysis. The biological assays bared a considerable antioxidant potential of selected green materials. Among vegetables, Trigonella foenum-graecum was proved to be superior while Brassica rapa rapa was considered to be inferior for phenolics and flavonoids content. Trigonella foenum-graecum also presented significant antioxidant activity with maximum reduction capacity and also having least IC50 as a result of inhibition of free radical scavenging by DPPH method. In contrast to α-amylase, a significantly higher inhibition towards α-glucosidase was shown by the selected samples; an impending remedial approach connected to postprandial hyperglycemia. In this scenario, the results of this study suggests that all the selected green materials have very good medicinal potentials, meet the standard requirements for drug formulation and serve as good sources of energy and nutrients. The outcomes of current work also revealed that plant derived foods enriched with phytoprotectants are effective to tailor specific healthy diet for the target population.

“…The promotion of grain legumes has been mainly linked to them being rich sources of protein, low in saturated fat, as well as possessing certain important micronutrients (zinc, folate and calcium and tocopherols) [11][12][13]. In this regard, legumes could contribute significantly to diets of rural households if consumed as compliments to starch.…”

Expounding the Value of Grain Legumes in the Semi- and Arid Tropics

Approximately 70% of the population in the semi-and arid tropics reside in rural areas and depend on agriculture for their livelihood. Crop production is primarily focused on a few starchy staple crops. While this can ensure adequate calories, it inadvertently neglects the need for dietary diversity. Consequently, food and nutritional insecurity remains prevalent in the semi-and arid tropics. We reviewed the legume value chain with the aim to identify opportunities and challenges to unlocking their value and promoting them in the tropics. Several grain legumes are rich in proteins and micronutrients. They also possess adaptability to marginal environmental conditions such as drought and low input systems which typify rural landscapes. Adaptability to abiotic stresses such as drought makes them key to agriculture in areas that will receive less rainfall in the future. However, this potential was currently not being realized due to a range of challenges. Aspects related to their seed systems, production, post-harvest handling and marketing remain relatively under-researched. This was especially true for minor legumes. There is a need for transdisciplinary research which will address the entire value chain, as has been done for major starchy crops. This could also unlock significant economic opportunities for marginalized groups such as women. This will unlock their value and allow them to contribute meaningfully to food and nutrition security as well as sustainable and resilient cropping systems.

BACKGROUND Kimchi, a Korean food, is now produced and consumed in many other countries. In this study, the macro, trace, and toxic element content in varieties of kimchi from Korea and China was evaluated. A health‐risk assessment, involving the calculation of estimated dietary intake values, was undertaken. To discriminate among samples with different origins, linear discriminant analysis (LDA) and principal component analysis (PCA) were applied. RESULTS The analytical methods used for analyses were successfully validated. In the quantification of elements, no significant differences were detected in the concentrations of the elements that were analyzed. Based on the fresh weight of kimchi, among the macro elements, the concentrations of Na and K were relatively high, with values of 4181.9–9919.8 mg kg−1 and 1661.8–6623.5 mg kg−1, respectively. Among the trace elements that were analyzed, zinc in Korean samples, and strontium in Chinese samples showed the highest concentrations, at 2.67 and 2.98 mg kg−1, respectively. Concentration levels of the toxic trace elements were within permissible limits. The amount of daily intake and provisional daily intake of each element calculated based on kimchi intake confirmed its safety for consumption. Linear discriminant analysis and PCA successfully discriminated among the samples of Chinese and Korean origin. CONCLUSION The provisional daily intake of the toxic elements was within provisional tolerable daily intake values. The normal intake of kimchi could not pose a threat upon consumption. © 2019 Society of Chemical Industry
