- The aim of the research was to evaluate the effect of consumption of selenium-enriched pork on selected health indicators of probands. The intake of feed mixture with increased organic selenium at the dose of 0.3 mg.kg⁻¹ probably increases selenium concentration in MSM (musculus semimembranosus). In the pork enriched with organic selenium, the concentration was higher by 1.045 ± 0.10 mg.kg⁻¹ compared with the control group 0.701 ± 0.05 mg.kg⁻¹ at significance P < 0.001. Sixteen participants in the experiment were represented by 8 men at the average age of 41.5 ± 11.9 years and 8 women at the average age of 41.4 ± 7.9 years. All the probands consumed meat enriched with selenium three times a week during one month. By consumption of the enriched pork, there was an increase of the selenium concentration in blood serum of probands traced with selenium increase from 73.19 ± 15.68 μg.L⁻¹ to 73.73 ± 15.13 μg.L⁻¹ (P > 0.05). From the results we can see that consumption of enriched pork with selenium was significantly manifested in lowering of total cholesterol levels, which was associated with LDL cholesterol lowering (P < 0.05). Differences among the HDL cholesterol and triglycerides samples were not significant.
