“…The anti-cancer properties of some of these polyphenols have been previously tested and confirmed. For instance, ellagic acid, quercetin, catechin, and phenolic acid prevented several kinds of cancer that affect the skin, stomach, duodenum, mouth, colon, liver, lung, and mammary glands (Yang et al, 2001;Okafor et al, 2022). Ade-Omowaye et al (2015) and independently confirmed the presence of antioxidant-related phytochemicals: phenolics and flavonoids in AYB.…”

“…In a comparative study of antioxidants produced by Bambara groundnut (BG) using methanolic extract, Salawu (2016) identified the presence of several polyphenols in the raw and cooked BG seeds after quantification using HPLC-DAD. A recent study identified catechin, epicatechins, rutin, quercetin, isoquercetin, kaempferol, luteolin, gallic acid, chlorogenic acid, caffeic acid, and ellagic acid as polyphenols found in BG (Okafor et al, 2022). Likewise, Harris et al (2018) compared the level of flavonoids in red and brown BG hulls and observed that the brown hull had the highest amount of rutin (24.46 ± 0,23 mg g -1 ) and myricetin (1.80 ± 0.77 mg g -1 ) while the phytochemicals chlorogenic acid and ellagic acids which are tannins, had their highest concentrations in red BG hulls (0.12 ± 0.19 mg g -1 ) and brown BG (0.11 ± 0.08 mg g -1 ) respectively (Harris et al, 2018).…”

Nutritional, functional, and bioactive properties of african underutilized legumes

Globally, legumes are vital constituents of diet and perform critical roles in maintaining well-being owing to the dense nutritional contents and functional properties of their seeds. While much emphasis has been placed on the major grain legumes over the years, the neglected and underutilized legumes (NULs) are gaining significant recognition as probable crops to alleviate malnutrition and give a boost to food security in Africa. Consumption of these underutilized legumes has been associated with several health-promoting benefits and can be utilized as functional foods due to their rich dietary fibers, vitamins, polyunsaturated fatty acids (PUFAs), proteins/essential amino acids, micro-nutrients, and bioactive compounds. Despite the plethora of nutritional benefits, the underutilized legumes have not received much research attention compared to common mainstream grain legumes, thus hindering their adoption and utilization. Consequently, research efforts geared toward improvement, utilization, and incorporation into mainstream agriculture in Africa are more convincing than ever. This work reviews some selected NULs of Africa (Adzuki beans (Vigna angularis), African yam bean (Sphenostylis stenocarpa), Bambara groundnut (Vigna subterranea), Jack bean (Canavalia ensiformis), Kidney bean (Phaseolus vulgaris), Lima bean (Phaseolus lunatus), Marama bean (Tylosema esculentum), Mung bean, (Vigna radiata), Rice bean (Vigna Umbellata), and Winged bean (Psophocarpus tetragonolobus)), and their nutritional, and functional properties. Furthermore, we highlight the prospects and current challenges associated with the utilization of the NULs and discusses the strategies to facilitate their exploitation as not only sources of vital nutrients, but also their integration for the development of cheap and accessible functional foods.

“…The main fatty acids in BGN are oleic (18:1 n-9), linoleic (18:2 n-6) and palmitic (16:0) representing 23, 36 and 21%, respectively (Yao et al ., 2015). BGN has both the omega 3-(n-3) and omega 6-(n-6) fatty acids among other polyunsaturated fatty acids (PUFA) (Okafor et al ., 2022) suggesting that its consumption would promote health benefits associated with these PUFA.…”

“…The presence of antinutrients, such as condensed tannins, interferes with the digestion and bioavailability of nutrients. Condensed tannins are polyphenolic compounds present in many legumes and range from 0.01 to 2.37 mg/m in BGN (Harris et al ., 2018; Okafor et al ., 2022). They inhibit protein digestion by inhibiting the proteolytic activity and forming indigestible complexes with protein, consequentially reducing the bioavailability of amino acids.…”

Bambara groundnut (Vigna subterranea L. Verdc; BGN) is an important legume grown mainly by small scale subsistence farmers in sub-Saharan Africa, in parts of Thailand and Indonesia. It has a high concentration of seed carbohydrate (55-70 %), protein (17-25 %), fat (1.4-12 %) and dietary fibre (5.2-6.4 %). A range of biotic and abiotic stresses together with socio-economic constraints affect its productivity, yield and quality. The changing climate

“…16 The Bambara groundnut has been primarily consumed as a roasted or boiled snack to ameliorate vision problems and joint pain, reduce nausea, diarrhea, and sexually transmitted infections, treat inflammation, and inhibit the development of cancer cells. [17][18][19] The Bambara groundnut is abundant and easily accessible in Indonesia, and is, therefore, a potential food supplement to overcome PD. 20 Hence, ascertaining the safety level of Bambara groundnut consumption for overcoming PD is essential.…”

BACKGROUND Protein deficiency (PD) can lead to kidney damage. Consuming plant-based proteins may improve this condition. Bambara groundnut (Vigna subterranea)has an essential amino acid score of 80%, which is higher than other legumes; thus, it is potent in overcoming malnutrition. This study aimed to determine the effect of Bambara groundnut supplementation on kidney histology in adult female mice with PD. METHODS The study was conducted for 2 months in randomly selected female mice. These mice were grouped into the control, PD, and PD supplemented with Bambara groundnuts at 100, 200, and 300 g/kg of feed. 1 day after the last treatment, the kidneys of the mice were collected and processed histologically using the paraffin method (stained with hematoxylin and eosin and Masson’s trichrome). Parameters for observation included histopathological scoring (glomerular and interstitial space fibrosis and tubular damage), kidney histomorphometry, and organ index. Semi-quantitative data were analyzed using the Kruskal–Wallis test, while quantitative data were analyzed using one-way ANOVA (followed by Tukey’s test) and nested t-test. Statistical analysis was performed using SPSS software version 20 (IBM Corp., USA) (p≤0.05). RESULTS PD caused cell sloughing (moderate level) and dilatation (severe level) of the kidney tubules. It also reduced glomerular diameter and area by approximately 17.66% and 29%, respectively. PD and Bambara groundnut administration had no significant effects on the glomerular number, cortex and medulla thickness, distal and proximal tubule diameter, and kidney organ index (p>0.05). CONCLUSIONS Bambara groundnut (V. subterranea) administration prevented damage to the kidney’s histological structure of protein-deficient mice.
