“…Studies in several animal species have indicated that the bioavailability of selenium from ®sh is $ 50% of that for selenite (Miller et al, 1972;Cantor et al, 1975;Alexander et al, 1983), but in other studies values between 50% and 100% were obtained (Ringdal et al, 1985;Mutanen et al, 1986;Hassan et al, 1987). The divergent results probably re¯ect the use of different animals and ®sh feeds, and variations in the methods for assessment of bioavailability (Mutanen, 1986).…”

Objective: To study the relationships between ®sh intake and different markers of selenium status and thyroid hormone function. Design: Cross-sectional study. Setting and subjects: Sixty-eight men (age 24±79 years) were recruited among coastal ®shermen and inland subjects from Latvia. None of the subjects was on selenium medication or had any known endocrine disease. Main outcome measures: Correlations between ®sh intake, plasma levels of selenium, selenoprotein P, glutathione peroxidase, organic mercury in erythrocytes and TSH in serum. Results: Selenium in plasma ranged from 0.30 to 1.56 mmola1, selenoprotein P from 0.54 to 2.21 arbitrary units relative to pooled plasma, and glutathione peroxidase from 1.20 to 5.73 mga1. The number of ®sh meals per month was correlated with plasma selenium, selenoprotein P and glutathione peroxidase (r 0.63, r 0.62 and r 0.50, respectively; P`0.001). Plasma selenium was correlated with selenoprotein P and glutathione peroxidase (r 0.88 and r 0.67, respectively; P`0.001), and also selenoprotein P and glutathione peroxidase were correlated (r 0.63, P`0.001). The mean plasma selenium level in those with a high ®sh intake (21±50 ®sh mealsamonth), was 81% higher than in those with lowest ®sh intake. TSH in serum was inversely correlated with plasma selenium and selenoprotein P. Thyroid hormone levels were not correlated with plasma selenium, selenoproteins or ®sh intake. Conclusions: In this study group, selenium from ®sh intake had a marked impact on all variables studied on selenium status. No impact of selenium status on T3 and T4 levels was observed. The slightly negative correlation of selenium status with TSH levels might indicate a higher TSH secretion at low selenium status.

“…In particular, Se in fish, which is one of the principal Se sources in the Japanese diet, has lesser bioavailability (13)(14)(15)(16). Thus, evaluation of the nutritional eficiency2 of fish-Se is important in qualitative assessment of Se intake in Japan.…”

“…RESULTS low availability of Se in processed skipjack meat. It has been found that the nutritional efficiency of Se in tuna meat is increased to an almost equal extent as selenite when tuna is digested in a mixture of nitric and perchloric acid (13). A chemical form of Se in skipjack meat is considered to be the most important factor for the low availability.…”

“…57,58) Although the selenium content in fish is high, there are fewer reports on the bioavailability of selenium from seafood than that from wheat, cereal, eggs, meats, etc. [59][60][61][62] In some cases, fish is not a rich source of bioavailable selenium, due in part to its high mercury content and other heavy metals, which bind to selenium. 10) Due to the formation of an insoluble complex with heavy metals, such as mercury, selenium from seafood, e.g., tuna, was thought to be less bioavailable than that from beef and wheat.…”

Research interests in studying the biochemical nature of selenium have increased and the importance of this element as an essential micronutrient in many organisms has been well recognized. Selenium occurs in proteins in the form of the 21st amino acid, selenocysteine (SeCys or Sec). In this review, we describe the speciation analysis of the fish-specific selenoproteins and non-proteinous selenium compounds, and the nutritional bioavailability of selenium from seafood materials. Selenium is essential to fish and shellfish. The selenoproteomes (sets of SeCys-containing proteins) of fish are greater in number than those of mammals (25 selenoproteins in humans); at 30-37 selenoproteins, the selenoproteomes of fish are among the largest known. The same core selenoprotein families are found in mammals and fish. In addition, fish have several species-specific selenoproteins [fish 15 kDa selenoprotein-like protein (Fep15), selenoprotein J and selenoprotein L] that are missing in mammals. Actually, not only proteinous selenium species like selenomethionine (SeMet) and SeCys derivatives, but also many non-proteinous organic ones were detected in fish and shellfish samples. Although the selenium contents in seafood are higher than in terrestrial foodstuffs, little is known about the chemical forms of organoselenium species in seafood. The nutritional bioavailability of selenium from seafood appears to be dependent on the fish and shellfish species and/or place where they are produced; some seafood gives rise to a high bioavailability of selenium, which is comparable to that of wheat and beef. Fish and shellfish materials are major dietary sources of selenium for the Japanese population (∼ 60% of daily intake). Seafood materials appear to contain nutritionally effective organoselenium compounds that have not yet been chemically identified.
