“…Trace metal elements are trace minerals present in living tissue (Geng et al, 2018). Some of them play important effects on the body health, such as participating in oxidation-reduction reactions in energy metabolism, acting as catalysts in enzyme systems; or involvement with oxygen transport (Konikowska and Mandecka, 2018) (Fig 4). In this study, it was found that different Se application methods promoted different behaviors in terms of essential trace elements contents (Fe, Zn, Cu, Co, Mo and Cr) in sink-source organs of 2 genotypes (Table 2).…”

Mineral nutrient malnutrition, especially deficiency of selenium (Se) affects the health of approximately one billion people worldwide. Wild emmer wheat (Triticum turgidum ssp. dicoccoides), the progenitor of common wheat, harbors a rich genetic diversity for mineral nutrients. The study was conducted on two wild emmer wheat genotypes differing in Se tolerance (R113, Se-sensitive; R171, Se-tolerant) with 2 Se application methods and 3 Se levels (foliar rates of 0, 11.5 and 23 mg. L-1 ; fertigation rates of 0, 5 and 10 mg. kg-1) in 2017 having 5 replications, at an experimental farm, Sichuan Province, China. It evaluated the effects of Se application on wild emmer wheat growth, grain yield and quality, and 14 other trace elements absorption and translocation in sink-source organs (flag leaves, husks and grains). The results showed that both foliar Se and fertigated Se application methods increased Se contents in sink-source organs, wheat health benefits and yield, while the foliar application was more effective than fertigation. Moreover, two Se application methods decreased toxic trace elements (Pb, Al, As, Li and Cd) contents in wheat, indicating a possible antagonistic effect. Accordingly, this study provided useful information concerning agronomic biofortification of wheat, indicating that it is feasible to apply Se in fertilization programmes to inhibit the heavy metal elements contents and improve yield and quality in agricultural crops. The higher Se, Fe, Zn and Mo contents found in R171 suggested that its germplasm conferred higher abilities for mineral uptake and accumulation, which can be used for genetic studies of wheat nutritional value and for further improvement of domesticated cereals.

“…Trace elements are importantly required for the human nutrition (Konikowska and Mandecka, 2018). These are required for the body functions in minute quantities but their deficiency may result in several health issues such as "hidden hunger" (Titcomb and Tanumihardjo, 2019).…”

“…Selenium is an essential trace mineral found in food of animal origin (meat and meat products, offal, fish, dairy products), in vegetables, such as cereals (rice and wheat) and nuts (mainly Brazil nuts), as well as in mushrooms [ 128 ]. This mineral is an indispensable component of glutathione peroxidase (GPx), an enzyme involved in the decomposition of both hydrogen peroxides and hydroperoxides produced during lipid oxidation [ 64 , 129 ].…”

Consumers’ perception of meat products has changed in recent years, which has led to an increased interest in healthier meat products. In response to this demand, academia and industry have made efforts to reformulate meat products, especially dry fermented meat products, which are known for their high fat contents, mainly saturated fat. The use of plant or marine oils stabilized in emulsion gels (EGs) or oil-bulking agents (OBAs) as animal fat replacers has been one of the most advantageous strategies to reformulate dry fermented meat products with a healthier lipid content (quality and quantity), but an increase in their polyunsaturated fatty acid content can trigger a significant increase in lipid oxidation, negatively affecting sensory and nutritional quality. The use of antioxidants is the main strategy to delay this deteriorative reaction, but the controversy around the safety and toxicity of synthetic antioxidants has driven consumers and industry toward the use of plant antioxidants, such as phenolic compounds, carotenoids, and some vitamins and minerals. This review provides information about the use of plant antioxidants to control lipid oxidation of dry fermented meat products with healthier lipids.

“…As nutrients, they are obtained from food, water, and the environment [ 7 ] and are usually needed in tiny quantities (traces) in the body [ 8 , 9 ]. Their toxicities are rare at the dietary intake level, as they are highly regulated by homeostatic mechanisms to avoid excessive levels and cannot be stored in the body [ 1 ].…”

Distribution and Determinants of Serum Zinc, Copper, and Selenium Levels among Children under Five Years from Popokabaka, Democratic Republic of Congo: A Cross-Sectional Study

et al. 2022

Information about essential trace elements among children in many African countries, including the Democratic Republic of Congo (DRC), is limited. We aimed to measure the distribution and determinants of serum zinc (Zn), copper (Cu), and selenium (Se) concentrations in a representative sample of children under five years old. We conducted a community-based cross-sectional study in Popokabaka, DRC. Blood samples were drawn from 412 children. The serum concentrations of minerals were measured using inductively coupled plasma–mass spectrometry. The median concentrations (P25–P75) of Zn, Cu, and Se were 61.9 µg/dL (52.8–70.2), 145.5 (120.0–167.0) µg/dL and 5.3 (4.3–6.3) µg/L. The CRP-adjusted prevalence of serum Se deficiency was 84.1% (95% confidence interval [CI] 81.4–87.0) and of Zn deficiency was 64.6% (95% CI 59.8–69.1%). Only a few children were Cu deficient [1.5% (0.6–3.2)]. Evidence of inflammation (C-reactive protein, >5 mg/L) was associated with a lower Se concentration and higher Cu concentration. Furthermore, serum Se concentration was positively associated with linear growth. The average Cu/Zn molar ratio (2:1) was twice that recommended. Children in western Popokabaka had higher Zn and Se levels than their eastern neighbors. Zinc and selenium deficiencies are common among children in Popokabaka and require attention and prioritization.
