“…The concentration of Ag, Co, Cr, Li, Mo, Ni, Pb in conventional and organic beetroots samples were determined under the LOQ ( Table 4 ). The observed variability in the analysed mineral concentration might be a result of the differences in plants’ geographical origin [ 34 ], fertilization [ 35 , 36 ], as well as varietal differences [ 37 ]. In the case of dietary supplements, Se, Cu, Ag, Co, Cr, Ba, Li, Mo, Ni, Pb concentrations were under the LOQ ( Table 5 ).…”

Mineral Composition of Dietary Supplements-Analytical and Chemometric Approach

et al. 2021

There is a lack of data on the actual composition and effectiveness of beetroot-based dietary supplements. The research aimed to determine the profile of 22 elements (Na, K, Ca, Mg, P, Fe, As, Se, Zn, Cu, Ag, Co, Ni, Mo, Al, Mn, Sr, Cr, Ba, Li, Pb, Cd) in beetroot and its supplements by the microwave plasma atomic emission spectrometry (MP-AES) method. The analytical procedure was optimised and validated. The composition of both groups was compared, assessing compliance with the recommended daily doses for the chosen elements, and the health risk was estimated. Furthermore, chemometric analysis was applied. Beetroots constituted a significant source of elements, especially K, Na, Mg, Ca, P, in contrast to supplements which contained their negligible amounts except from iron-enriched products which provided notable amounts of Fe (38.3–88% of the Recommended Dietary Allowance for an adult male from 19 to 75 years old). Some products were significantly contaminated with toxic elements (As, Cd). Factor and cluster analyses were helpful in the differentiation of beetroot and its supplements in view of their type (vegetable, supplement, iron-enriched supplement), origin, type of cultivation (conventional, organic), and form (capsule, tablet) based on their mineral composition. The obtained results indicate the need for more stringent control of supplements, as they may pose a significant health risk to consumers.

Essential trace elements in the African spider plant (Cleome gynandra). A case study in Molo Ward, Nakuru, Kenya

et al. 2023

In Kenya, cases of malnutrition and nutritionally related ailments have been on the rise. This calls for the search for food crops with vital trace elements. The aim of the current study was to use energy dispersive X‐ray fluorescence spectroscopy (EDXRF) to determine the concentrations of Zn, Fe, Cu, and Mn in the stems and leaves of the African spider plant (Cleome gynandra) in the context of nutrition. Stems and leaves of the African spider plant grown in the highland and in the lowland of Molo Ward, Nakuru, Kenya, were found to contain total available Zn in the range of 140 ± 50 to 230 ± 60 mg/kg, Fe in the range of 2200 ± 700 to 3900 ± 1700 mg/kg, Cu at 13 ± 3 to 16 ± 5 mg/kg, and Mn at 380 ± 120 to 400 ± 140 mg/kg. There was no significant difference in the average concentrations of the trace elements in the leaves and stems of the African spider plant from the lowland and highland regions of Molo Ward (p > 0.05). The concentrations of Zn, Fe, Cu, and Mn in the African spider plants is high enough to make it a nutritious traditional vegetable. Therefore, farmers should be encouraged and empowered to grow more vegetables.

“…Numerous studies of urban and peri-urban farming worldwide have demonstrated that it effectively improves household food security (Michailidis, D.L. and D. Lazaridou, 2020, Moorthy, D., et al, 2020, Ndunge, G., et al, 2020. Peri-urban farming is also practical as an income-generating activity (Ndunge, G., et al, 2018).…”

“…According to a study conducted by Ndunge, G., et al, (2020), nearly 73,000 children in Kenya were severely malnourished and at risk of dying from drought-related hunger. The survey also revealed that almost 40,000 pregnant and nursing women across Kenya were malnourished, a 20% increase from 2016, leaving them and their children's health in a precarious position, says.…”

Urban areas worldwide have experienced a surge in population growth in recent times. The rapid increase in the urban population brings about many challenges to food security. With the increase in urban poverty, there is a renewed interest in looking at alternative strategies for improving urban livelihoods. Urban food insecurity is an emerging challenge exacerbated by climate change, low income, and limited access to land. In many developing countries, the growing urbanization brings about poverty, food insecurity, malnutrition, and other challenges. Many children in Kenya are severely malnourished and risk dying from drought-related hunger (Quintana, D. and H. Wenban-Smith, (2020). Pregnant and nursing mothers across Kenya may suffer from malnutrition thus adversely affecting their children’s health. Alternative farming in urban areas represents an avenue for increasing food supply, bettering health conditions and providing a source of income. This paper explored the use of alternative farming to address malnutrition. The study adopted a cross-sectional design and utilized qualitative data collection methods and analysis. The target population comprised women who are beneficiaries of the CBO. Purposive sampling was used to select 15 women who were interviewed. Data were analyzed by thematic analysis. The findings demonstrated improved diet intake, food security, knowledge in nutrition, reduced household malnutrition, improved health in adults and children, and economically empowered women.
