“…Excess Se intake is known to cause harmful effects (31), and Se supplementation of food should be carefully considered since this could increase the risk of Se toxicity (28). At concentrations higher than those necessary for fulfilling requirements, Se can cause selenosis (15), type 2 diabetes (20), and endocrine disruption by impairing synthesis of thyroid hormones (28) and can be genotoxic and carcinogenic (20,41). At a biochemical level, Se can induce oxidative stress (by upregulation of antioxidant proteins) and redox cycling of auto-oxidizable Se metabolites; cause glutathione depletion, protein synthesis inhibition, depletion of S-adenosyl-methionine (cofactor for selenide methylation), and general replacement of sulfur; and cause reactions with critical sulfhydryl groups of proteins and cofactors (reviewed in European Commission (7) and Jablonska and Vinceti (20)).…”

“…Se concentration in Atlantic salmon flesh was lower when fed on plant protein replacement feeds compared with marine protein feeds (4). Se is a well-known essential trace element (41) that is active as part of functional selenoproteins (24) involved in physiological processes such as antioxidant defense (glutathione peroxidases) (41) and thyroid homeostasis (deiodinases) (35). Of all food products, seafood has some of the highest natural background Se levels (8,41).…”

Several studies on fish nutrition have recommended Se supplementation to plantbased feeds to restore or maintain Se levels in farmed fish as a Se source for consumers (4,30).…”

This study investigated the transfer kinetics of dietary selenite and selenomethionine (SeMet) to the fillet of farmed Atlantic salmon (Salmo salar). The uptake and elimination rate constants of the two selenium (Se) forms were determined in Atlantic salmon fed either selenite- or SeMet-supplemented diets followed by a depuration period. The fillet half-life of selenite and SeMet was 779 ± 188 and 339 ± 103 days, respectively. The elimination and uptake rates were used in a simple one-compartmental kinetic model to predict levels in fillet based on long-term (whole production cycle) feeding with given dietary Se levels. Model predictions for Atlantic salmon fed plant-based feeds low in natural Se and supplemented with either 0.2 mg of selenite or SeMet kg−1 gave a predicted fillet level of 0.042 and 0.058 mg Se kg−1 wet weight, respectively. Based on these predictions and the European Food Safety Authority risk assessment of Se feed supplementation for food-producing terrestrial farm animals, the supplementation with 0.2 mg of selenite kg−1 would likely be safe for the most sensitive group of consumers (toddlers). However, supplementing feed to farm animals, including salmon, with 0.2 mg of SeMet kg−1 would give a higher (114%) Se intake than the safe upper intake limit for toddlers.

“…For Se, safety margin between adequate amount and overconsumption is narrow in humans and other mammals, so it has become more important to estimate the Se intake ( Reis et al, 2017 ; Ullah et al, 2018 ). In addition, deficient or excessive Se intake depends on regions because the Se concentration in vegetables can be largely affected by Se concentration in soil ( Reis et al, 2017 ).…”

“…Natural and anthropogenic sources of Se including bedrocks, volcanic activity, Se-fertilizers, and coal burning influence the Se concentration in soil ( Winkel et al, 2015 ), and this subsequently can affect the Se concentration in plants and animal body. Moreover, livestock products have relatively high Se concentration compared with fruits and cereals ( Choi et al, 2009 ; Ullah et al, 2018 ). It has been reported that Se concentration in organs and tissues of pigs increased as dietary Se concentrations increased ( Goehring et al, 1984 ; Kim & Mahan, 2001a ; Kim & Mahan, 2001b ; Mateo et al, 2007 ).…”

The experiment was conducted to determine the effects of graded dietary selenium (Se) on organ weight and Se concentrations in tissues and to develop equations for estimating dietary Se intake in pigs. Sixteen barrows (initial body weight = 30.0 ± 2.6) were allotted to four dietary treatments including graded Se supplementations with 0, 1, 5, and 50 mg/kg of diet. The experimental diets fed to the pigs for 30 d, and then the pigs were euthanized, and the organs, muscle, and urine samples were collected. The hair and blood samples of pigs were collected on d 15 and 30. Equations were developed for predicting daily Se intake using the Se concentration in plasma, hair, liver, kidneys, muscle, or urine. For graded dietary Se concentrations, linear and quadratic effects on the final body weight, weight and relative weight of liver and kidneys were not observed. The Se concentration in plasma, hair, liver, kidneys, muscle, and urine were linearly and quadratically increased as dietary Se concentration increased (P < 0.001). The dietary Se concentration was positively correlated with the Se concentrations in the plasma, organs, muscle, and urine (r > 0.81, P < 0.001). The equations for estimating dietary Se intake using the Se concentration in the plasma, hair, or organ as an independent variable were significant (P < 0.05). In conclusion, the dietary Se concentration was well reflected in the Se concentration in the plasma, hair, liver, kidneys, and urine. The Se concentration in the plasma, hair, liver, and kidneys can be used as an independent variable for estimating the Se intake.

Background:The relationship between serum selenium level and gestational diabetes mellitus (GDM) is controversial. The purpose is to update and summarize previous studies to understand the relationship in more detail.Methods: PubMed, The Cochrane Library, EMBASE, Web of science, CNKI, WAN-FANG DATA and Cqvip were searched for studies published up to 3 September 2021. The random-effects model was used to measure the combined estimation.The overall effect was reported in a standard mean difference (SMD) and 95% confidence interval (95% CI). All data were analysed by Review Manager 5.4. Results:Twenty-seven studies involving 1588 patients with GDM and 2450 healthy pregnant women contributed to this meta-analysis. Selenium level was significantly lower in women with GDM than those without GDM (SMD = −1.
