“…Meat, poultry and fish, bread and cereals, and milk and dairy products are the food groups that provide most of the total Se in the diets of northern Europeans (see review by Van Dokkum, 1995). Over the past two decades Se intakes have fallen in the UK and elsewhere in Europe (Rayman 1997).…”

Modifications were made to the food compositional database to take account of recently reported Se levels in Irish and UK foods, especially bread and cereals, meat and fish, and milk and dairy produce (Murphy & Cashman, 2001), which are the food groups that provide most of the total Se in the diets of northern Europeans (see review by Van Dokkum, 1995). For food groups other than these, Se values were updated using data recently reported for UK foods by Barclay et al (1995).…”

Objective: To measure the intake of selenium (Se) and the contribution of different food groups to Se intake in adults aged 18 -64 y in Ireland. The adequacy of Se intake in the population is also assessed. Design: Food consumption was estimated using a 7 day food diary for a representative sample (n ¼ 1379; men ¼ 662, women ¼ 717) of 18 -64-y-old Irish adults selected randomly from the electoral register. Se intake was estimated using updated tables of food composition. Results: Mean daily Se intakes ( AE s.d.) from all sources (ie food plus supplements), and from food sources alone, for the group of Irish adults aged 18 -64 y were 52 ( AE 23) and 50 ( AE 21) mg, respectively. Mean daily Se intake (from all sources) was significantly higher in men of all ages than women of all ages at levels of 60 and 44 mg, respectively (P < 0.001). Meat=meat products (30%), bread and rolls (24%), fish=fish products ( $ 11%), and milk and yoghurt (9%) were the main contributors to mean daily Se intake. Adequacy of Se intake in population groups was estimated as the percentage of the population with mean daily Se intakes that were lower than the average requirement of 40 mg. Using this measure, 45.6% of women and 17.1% of men had inadequate Se intakes.

“…In addition, it has attracted much interest as an anticancer agent because of its role as an antioxidant (Combs & Clark, 1999;Rayman, 2000). Interest in selenium in the diet has been provoked by the observation that selenium intakes in some European countries have been falling over the last 15 y (Barclay & McPherson, 1992;Van Dokkum, 1995).…”

Bioavailability of selenium from fish, yeast and selenate: a comparative study in humans using stable isotopes

et al. 2004

View full text Add to dashboard Cite

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.

“…These ®ndings may have consequences for bone health of many adults because, while mean daily Cu intakes of adults in Europe (1.0 ± 2.26 mg for males, 0.9 ± 1.79 mg for females, Van Dokkum, 1995) are greater than or close to the EU population reference intake (PRI; 1.1 mgaday for adults; Report of the Scienti®c Committee for Food, 1993), there may be signi®cant numbers of individuals with marginal Cu intakes. For example, Klevay et al (1993) suggests that more than 30% of diets in North America and Europe provide less than 1.0 mgaday.…”

“…For example, Klevay et al (1993) suggests that more than 30% of diets in North America and Europe provide less than 1.0 mgaday. Moreover, this effect of marginal Cu intake on bone health may be more of a concern for females than males because, in general, total Cu intake by women is less than that by men (Johnson et al, 1992; see review by Van Dokkum, 1995).…”

No effect of copper supplementation on biochemical markers of bone metabolism in healthy young adult females despite apparently improved copper status

et al. 2001

View full text Add to dashboard Cite

Objective: To investigate the effects of increasing Cu intakes, above the usual dietary intake, on biomarkers of bone metabolism in healthy young adult females (aged 21 ± 28 y) over a 4 week period. Design: A double-blind, placebo-controlled randomised repeat crossover Cu supplementation trial. Setting: The study was conducted at the Royal Veterinary and Agricultural University (RVAU), Copenhagen, Denmark. Subjects: Sixteen healthy young adult females aged 20 ± 28 y were recruited from among students at the RVAU. Intervention: During the 4 week intervention periods in this randomised, crossover trial (3Â4 weeks with a minimum 3 week wash-out period), each subject received, in addition to their usual diet, either 3 or 6 mg elemental Cuaday as CuSO 4 or a matching placebo. On the last 3 days of each dietary period 24 h urines were collected. In addition, blood was collected on the last day of each dietary period. Results: Serum Cu and erythrocyte superoxide dismutase (but not caeruloplasmin protein concentration or activity (putative indices of Cu status)) were signi®cantly increased (P`0.05) after daily Cu supplementation with 3 and 6 mgaday for 4 weeks. Serum osteocalcin (biomarker of bone formation), urinary creatinine (Cr) concentration, urinary pyridinoline (Pyr)aCr or deoxypyridinoline (Dpyr)aCr excretion, or daily urinary Pyr or Dpyr excretion (biomarkers of bone resorption) were unaffected by Cu supplementation. Conclusion: Copper supplementation of the usual diet in healthy young adult females, while apparently improving Cu status, had no effect on biochemical markers of bone formation or bone resorption over 4 week periods.
