Mineral Constituents

Nutritional drinks (NDs) are medicinal food products intended for people with different health issues constricting nutrients provision. Eight varieties of milkshake style NDs were analyzed in this work. Prior to element analysis, they were freeze-dried, and concentrations of twenty macro- and microelements in analyzed samples were simultaneously measured by ICP-OES after their mineralization in a closed-vessel microwave-assisted digestion system. Results of this analysis indicated that these NDs must be considered as nutrient-dense foods, taking into account mineral constituents. Consumption of two bottles of such NDs per day provides very a high amount or even an excess of human daily requirements set as Recommended Dietary Allowances (RDAs). Generally, concentrations of determined elements in examined NDs were consistent with data given on the labels—most of differences did not exceed 30% (median: −5.91%, standard deviation: 14%). Discovered very strong and moderate positive correlations between concentrations of major and essential elements (Ca, Mg, P, Cu, Fe, Mn, Zn) were likely due to their incorporation into formulations of analyzed NDs. However, relationships between contents of trace elements were the result of concomitance of these elements in substrates used for examined products production or contamination of substrates.

ABSTRACT The study has been conducted with inductively coupled plasma optical emission spectrometry to determine the content of toxic heavy metals, macroelements, and essential elements in two species of bivalves of commercial interest in the Canary Islands: the Mediterranean mussel (Mytillus galloprovincialis, Lamarck 1819) and the razor clam (Ensis directus, Conrad 1883). The study included 40 samples corresponding to 20 specimens of each species acquired from fishmongers on the island of Tenerife. E. directus had higher levels of metals, except for B, Cd, Na, and Zn (0.98, 0.02, 2,006.93, and 15.07 mg/kg, respectively) compared with those in M. galloprovincialis, B, Cd, Na, and Zn (2.67, 0.12, 2,267.7, and 22.27 mg/kg, respectively). In both bivalve molluscs, the maximum limits established by European legislation on food for human consumption were not exceeded. Likewise, the estimated daily intakes for the toxic metals Pb and Cd were below the admissible daily intakes.

Abstract. The authors of this paper decided to check whether the content of selected minerals in human hair is projected into the nutritional status of the body expressed as the BMI. The study focused on evaluating the content of calcium, sodium, potassium and magnesium in the hair of 7845 individuals in relation to their BMI. 5126 women and 2719 men aged from 18 to 92, domiciled throughout Poland, were involved in the study. Hair samples were taken from several points of the occipital scalp. Ca, Na, K and Mg in the hair were determined using inductively coupled plasma optical emission spectrometry (ICP-OES). The content of Ca and Na in the hair of obese people (>30.0 kg·m2) was higher (323 mg·kg−1 and 180 mg·kg−1) in comparison with the groups of people with normal body weight and those grade 2 underweight (<16.9 kg·m2): 191 mg·kg−1 and 103 mg·kg−1 respectively. The highest level of K (317 mg·kg−1) was found in the hair of people classed as grade 2 underweight. The body mass index caused no differentiation in the content of Mg in hair. Positive correlations were found between Ca-Na, Ca-Mg and Na-Mg and between the BMI of the subjects and the content of Ca in hair (R = 0.163; p < 0.01) and between the BMI and the content of Na (R = 0.191; p < 0.01). On the other hand, a negative relation between K and the BMI was correlated only to an infinitesimal degree (R = −0.030, p < 0.01). The results point to a relationship between the body mass index and the content of Ca, Na and K in the hair of adults.

The aim of this study was to determine the concentration of macroelements (Ca, Na, K, Mg) and essential elements (Zn, Fe, Se, Cu) in milk and yoghurt collected from the Croatian market. Inductively coupled plasma-optical emission spectrometry was used as an analytical technique. Mean concentrations measured in milk and yoghurt were (mg/kg): Ca 1406.9 and 1153.8, K 1995.5 and 1526.5, Na 608.3 and 519.2, Mg 136.4 and 108.0, Zn 3.92 and 3.48, Fe 0.332 and 0.231, Cu 0.005 and 0.124. Significantly higher concentrations of Ca, K, Na and Cu (p<0.01-p<0.001) were found in milk than in yoghurt. The element concentrations measured in milk, with the exception of higher K and Na levels, were in agreement with the literature data. Variations in the content of all elements in yoghurt were found in comparison to data from other countries. These results represent the first data on macro- and microelements from the Croatian market. The variations found in comparison to other countries suggest that unique processes are utilized in the production of yoghurt products.
