“…Alimentary studies show that the selenium status is highly dependable on dietary sources [18], particularly on their protein content [19][20][21][22]. Therefore animal food with its high protein content could be regarded as a vast source of this element.…”

Background: A serum selenium concentration of 70 µg/l is considered to be sufficient for glutathione peroxidase (GSHPx) activity, a selenium-dependent enzyme reflecting the body selenium status. The purpose of the study was to assess which foods or food groups best affect serum selenium in subjects with selenium concentrations below or above 70 µg/l. Methods: A food frequency questionnaire was employed to describe the dietary habits of 129 subjects. Serum selenium concentrations were determined using the electrothermal absorption spectrometry (ETAAS) technique following serum dilution. Results: Multiple regression analysis revealed that consumption of ham, honey and tea was positively associated with the selenium concentration in the sera of selenium-inadequate subjects. In selenium-inadequate subjects, alcohol consumption may be responsible for selenium losses. Unlike the selenium-inadequate subjects, the selenium concentrations in the sera of the selenium-adequate subjects were positively correlated with the frequencies of wholegrain bread consumption and processed fruit consumption. In all the groups tested, the serum selenium concentration was not affected by cigarette smoking. Conclusions: The serum selenium concentration is influenced by dietary habits, but not by cigarette smoking. Frequent consumption of ham, tea and honey may be effective to improve the selenium concentration in the sera of selenium-inadequate subjects.

“…The regression analysis demonstrated the significant correlation (connection) between the analyzed variablesselenium levels in liver and dark muscle, while upon the analysis of variance correlation coefficient of 0.743 was obtained. By measuring that correlation in human tissues the results of 0.613 was obtained [18].…”

The selenium content in dark muscle and liver was determined in chicken meat. All samples had been collected from three large meat producing companies in Croatia. The samples were wet digested with a mixture of nitric and perchloric acids. The selenium content was analyzed by hydride generation atomic absorption spectrometry with the recovery from 97.8 to 98.2%. The correlation coefficient of 0.976 was determined after comparison with results of the fluorimetric method. Mean +/- standard deviation of the selenium concentration (ng Se/g dry matter) was 1330 +/- 20, 2000 +/- 30 and 2090 +/- 30 in liver, and 560 +/- 50, 520 +/- 70 and 740 +/- 50 in dark muscle.

“…Daily Se intake below 55 µg day -1 was reported for European countries such as Greece, Turkey, Spain, Poland, Croatia and Austria while Switzerland and Netherlands had above 60 µg Se day -1 [109]. In Germany, the dietary selenium intake of men is 47 µg day -1 and that of women 38 µg day -1 (Oster and Prellwitz, 1989). Animal protein was the main source of dietary selenium in Germany accounting for 65.5% of the total selenium intake [117].…”

Selenium (Se) dependent enzymes play important roles in physiological functions such as thyroid hormone metabolism, strengthens anti-oxidant defense system and immune system. However, about 800 million people worldwide are believed to be deficient in Se which is attributed to low Se levels in the soil. This is because Se in plant and animal products in human diet depends upon the available Se in the soil. Deficiency of Se can be prevented or treated by adequate dietary intake or through direct supplementation. There have been reports that patients with dilated cardiomyopathy, HIV viral loads and cancer have responded to Se supplementation. However, food fortification has been found to be more efficient than supplementation. Both agronomic biofortification and genetic biofortification have been used to increase Se content of food crops and animal products. Genetic engineering makes use of key genes of Se hyperaccumulators to increase Se accumulating potential of food crops. Agronomic biofortification increases Se content of food crops by adding Se rich fertilizers to the soil or foliar application of Se. Selenium can also be added to animal diets or feedstuff to increase Se content of meat, eggs, and milk. Although inorganic forms of Se are approved as feed additives, they are less efficient than organic sources such as selenomethionine (SeMet) which is the dominant form in plants and animals. Animal products have been found to have higher Se content than plant products with fish having the highest Se content. Fruits and vegetables have a low content of Se probably because of their low protein content. Recommendations for dietary intake of Se vary with country, age and sex. There are concerns that the present recommended Se daily allowance may not be adequate due to discovery of other selenoenzymes with higher Se requirements than gluthathione peroxidase. There may be a need to review the current recommended daily allowance for Se in order to improve human health.
