“…Current interest in the interrelationships of Se with other nutrients requires the discussion of previous methods of assessing selenium status, following Robinson and Thomson (1983), Burk et al (1981), Burk (1986), Mutanen (1986), Levander (1986), Van Faassen et al (1987), Van den Haute et al (1987), Neve et al (1987), and Luten et al (1987). The selenium content of isolated erythrocytes, for example, reflects the average selenium intakes during the past 3 -4 months, as this period corresponds to the average life span of human erythrocytes.…”

“…One way to quantify the absorbable fraction, as one of the variables in trace element bioavailability , is with in vitro simulations of the digestive processes. In vitro methods have already been employed in bioavailability studies of iron, zinc, copper, selenium, cadmium (Miller et al 1981, Kane and Miller 1984, Hazell and Johnson 1987, Luten et al 1987, Southon et al 1988, Southgate et al 1989). …”

An in vitro method was used to study the dialysable fraction of chromium (Cr) from the diet which simulates human gastric and intestinal digestion. The percentage of dialysed Cr was used to assess the bioavailability. The duplicate diet approach was used to obtain ten different sets of samples each representative of the normal diet consumed in southern Spain. In each case triplicate analysis of Cr was carried out by electrothermal atomization-atomic absorption spectrometry in acid-mineralized samples. The Cr dietary intake ranged from 16 to 117 microg/day, and the dialysable Cr fraction ranged from 0.4% to 1.6%. The Cr absorption was higher for low levels of daily dietary intake of Cr (< 40 microg) than for levels of 40-80 microg; for high levels (> 80 microg) there was an increase in the dialysable fraction. The energy and nutrient intake of these diets was also evaluated.
