The aim of the work is a comparative study of the effect of vegetable nutrients - wheat germ oil (WGO), flour from wheat germ cake (WGC), and animal - concentrated tissue fish oil, origin on lipid metabolism indicators of students and university teachers, as well as an assessment of the probiotic factor in increasing the effectiveness of the target biologically active substances. The data obtained confirm the relation between the nutritional sufficiency of the body and the increase in lipid metabolism effectiveness and atherosclerosis risk reduction in students and teachers of an engineering university with the daily use of bioactive nutrients: WGO, WGCF, CTFO and their combinations with the biomass of lactobacilli and bifidobacteria consortium. The lipid metabolism was evaluated based on the analysis of indicators of the total cholesterol (TC) concentrations, high-density lipoproteins (HDL), low-density lipoproteins (LDL), triglycerides (TG), atherogenic index (AI). The values of these indicators were recorded before and after daily consuming the study foods for 30 days. The data obtained were analyzed for 3 age groups: 16 – 24, 25 – 44, and 45 – 65. It was found that WGO has the most effective antiatherosclerotic effect; the decrease in the TC level was 6.4%, the increase in the HDL concentration was 13.7%, the decrease in the LDL concentration was 11.3%, the decrease in the TG concentration was 17.1%, and the AI decreased by 22.6%, respectively. With WGCF, the changes in the studied parameters were 6.0, 12.3, 13.1, 13.1, and 22.1%, respectively. Together with probiotics WGO effectiveness increased in terms of the reduced TC level (1.9%), increased HDL concentration (8.2%), decreased LDL concentration (2.5%), reduced TG concentration (5.7%), and decreased AI (6.3%) for CTFO by 9.1, 26.1, 14.7, 24.1 and 31.2%, respectively. Thus, the dynamics of lipid metabolism indices objectively testifies to the positive effect of bioactive nutrients on human health indicators.
