“…Potential deficiencies and toxicities. The mineral levels in the grain samples analysed are in line with the literature for B, Cd, Cu, Fe, K, Mg, Mn, Na, Pb, and Zn [34][35][36][37] . The mean concentration of Cu, Fe, K, Mg, Mn, and P in the grain was enough to make nutritional food claims following Regulation (EU) No 1169/2011 38 .…”

Cultivar diversity in the mineral content of wheat grain under different nitrogen regimes.

Wheat is an important source of mineral nutrients in human diet. However, modern high-yield varieties have lost nutritional value relative to older ones. To correct this situation, we need to identify varieties with higher mineral concentrations in the grain and develop agronomic practices that favour nutrient accumulation in the grain. Here we compared nitrogen fertilization versus genetic variability as drivers of mineral content in the grain of wheat in Mediterranean semi-arid conditions, and alkaline soils. To do so, 12 winter wheat modern cultivars from different European provenance were grown on two consecutive years at three levels of top dressing N fertilization: optimal (105 Kg N ha-1); -50%; and +30%. The variety was the most important factor affecting the mineral concentration in the grain, followed by the climatology of the year. The N-regime had very little effect. The cultivar CH-Nara had both the highest Ca, Fe, Mg, Mn, N, P, S, and Zn and the lowest GY.

“…Due to the fact that cereals are a major part of the human diet, high content of minerals and especially of Zn and Fe in cereals has the potential to contribute substantially to human health and well-being [ 8 , 13 , 19 , 20 , 21 ]. Thus, minerals content in cereals and cereal-based food have been evaluated in a range of studies [ 22 , 23 , 24 , 25 , 26 , 27 ]. Furthermore, large international breeding programs, such as the CIMMYT spring wheat program, has focused on biofortification breeding to combine high yield and wide adaptation with high grain Zn content and processing quality [ 28 , 29 , 30 , 31 ].…”

Consumer interest in local and organic produce, sustainability along the production chain and food products contributing to health, are laying the foundation for local and organic-based diets using nutrient-dense food. Here, we evaluated 25 locally adapted landrace and ancient spring cereal genotypes per location over four locations and three years, for mineral content, nutritional yield and nutrient density. The results showed a large variation in minerals content and composition in the genotypes, but also over cultivation locations, cultivation years and for genotype groups. Highest minerals content was found in oats, while highest content of Zn and Fe was found in ancient wheats. The wheat Diamant brun, the wheat landrace Öland and naked barley showed high mineral values and high content of Zn and Fe when grown in Alnarp. Nutritional yield, of the cereals evaluated here, was high related to values reported internationally but lower than those found in a comparable winter wheat material. The nutrient density was generally high; less than 350 g was needed if any of the evaluated genotype groups were to be used in the daily diet to reach the recommended value of Zn and Fe, while if the suggested Novel Nordic Diet mix was used, only 250 g were needed. A transfer from currently consumed cereals to those in the present study, along the New Nordic Diet path, showed their potential to contribute as sustainable and nutrient-rich sources in the human diet.

“…Likewise, Ca-dense okra pod accessions (OPA#3 and OPA#6) would contribute only 4.2% of AI for Ca from 68 g fresh weight fruit consumption during pregnancy and lactation [ 34 ]. Yet, for young children aged between 1 and 3 years, it is worth to note that a 42 g serving portion of okra and/or okra-based traditional sauces could provide to the AI for Ca exceeding several-folds the percentage contributions that would be obtained from the consumption of various cereal-based foods in SSA [ 36 – 38 , 89 , 115 ]. Regarding P and Mg, 68 g Ethiopian okra (low-end consumption probability for PLW) has proved to be significant, potentially contributing ≥ 20% of their corresponding RDA values.…”

“…Similarly, the cultural acceptance of okra as a food crop indicates that it could be an important source of minerals in the diet if missing information about the mineral composition could be documented [33]. Attempts have been made to determine the mineral composition of several African food crops using various methodologies, which demonstrates varied accuracy [34][35][36]. For example, the standard wet laboratory procedures can reveal mineral contents as accurately as possible but wet digestion analysis is chemical intensive, laborious, expensive and time-consuming and requires well experienced technicians [33].…”

Okra (Abelmoschus esculentus) in a refugee context in East Africa: Kitchen gardening helps with mineral provision

et al. 2021

Kitchen gardening is considered a way to reconnect with agriculture and complement the cereal-based relief food offered to refugees in East Africa. This work aimed at profiling mineral content of okra in four refugee camps and settlements located in Ethiopia and Uganda and its contribution to adequate intake (AIs) or recommended dietary allowances (RDAs) for young children and pregnant and lactating women (PLW). The study also evaluated the applicability of portable X-ray fluorescence (PXRF) as compared with inductively coupled plasma mass spectrometry (ICP-MS) for mineral profiling of okra powder samples. The contents of minerals (mg kg−1) from the ICP-MS readings were in the following ranges: K (14,385–33,294), Ca (2610–14,090), P (3178–13,248), Mg (3896–7986), Cu (3.81–19.3), Fe (75.7–1243), Zn (33–141) and Mn (23.1–261). Regardless of geographic origin, at low-end consumption probability (17 g day−1 for young children and 68 g day−1 for PLW), okra could contribute ˂ 15% (2.7–12.9%) AI for macro-minerals (K and Ca). In addition, the contributions to RDA values for Fe and Zn, elements of known public health interest, ranged from 4.5 to 34.7% for young children. Interestingly, regression lines revealed strong agreement between ICP-MS and PXRF readings for Mn and Zn, with R2 values > 0.91. This information is useful in support of nutrition-sensitive kitchen gardening programs through scaling culturally important crops in refugee settings.
