“…The other possibility is that selenium requirement may differ between fish species (Lorentzen et al 1994). It is reported that the concentration range in which selenium is considered toxic or nutritional required for fish is very constricted (Watanabe et al 1997).…”

“…In fish, it has been observed that organic Se is more readily absorbed, and more potent in terms of bioavailability and effects on health, than inorganic forms (Lorentzen et al 1994;Wang & Lovell 1997;Wang et al 2007). In feedstuffs, Se is naturally present organically bound in Se containing proteins.…”

“…The content of selenium in the edible part of fishery products varies within a rather small range from 0.2-0.9 mg Se/kg (Food Standards Agency, 2002). Lorentzen et al (1994) demonstrated that feeding selenomethionine increased the selenium content of the fillet of farmed salmon trout more efficiently than inorganic selenium sources. However, insufficient information is available regarding the effect this kind of Se-enrichment has on the bioavailability of selenium from fish.…”

Objective: To measure the bioavailability of selenium from cooked and raw fish in humans by estimating and comparing apparent absorption and retention of selenium in biosynthetically labelled fish with labelled selenate and biosynthetically labelled selenium in brewers yeast. Design: The intervention study was a parallel, randomised, reference substance controlled design carried out at two different centres in Europe. Setting: The human study was carried out at the Institute of Food Research, Norwich, UK and at TNO Nutrition and Food Research, Zeist, The Netherlands. Subjects: In all, 35 male volunteers aged 18-50 y were recruited; 17 subjects were studied in Norwich (UK) and 18 in Zeist (Netherlands). All of the recruited subjects completed the study. Interventions: Biosynthetically labelled trout fish (processed by two different methods), biosynthetically labelled brewers yeast and isotopically labelled selenate were used to estimate selenium apparent absorption and retention by quantitative analysis of stable isotope labels recovered in faeces and urine. Subjects consumed the labelled foods in four meals over two consecutive days and absorption was measured by the luminal disappearance method over 10 days. Urinary clearance of isotopic labels was measured over 7 days to enable retention to be calculated. Results: Apparent absorption of selenium from fish was similar to selenate and there was no difference between the two processing methods used. However, retention of fish selenium was significantly higher than selenate (Po0.001). Apparent absorption and retention of yeast selenium was significantly different (Po0.001) from both fish selenium and selenate. Conclusion: Fish selenium is a highly bioavailable source of dietary selenium. Cooking did not affect selenium apparent absorption or retention from fish. Selenium from yeast is less bioavailable.

“…Moreover, most previous experiments in dietary Se requirements for rainbow trout and Atlantic salmon were conducted using mineral Se (Hilton et al, 1980;Bell et al, 1986Bell et al, , 1987Talas et al, 2008). This has been reported to have lower bioavailability and trophic transfer properties compared with organic Se (selenomethionine) (Lorentzen et al, 1994;Wang and Lovell, 1997;Fan et al, 2002).…”
