Introduction. Consumption of nutrients promoting the normalization of lipid metabolism allows correcting dyslipidemia, which is important for people engaged in mental work.

Purpose. An assessment of blood lipids in persons engaged in mental work that is harmful due to the intensity of the work process, when including in their diet a product made from plant materials.

Materials and methods. The study involved men aged 35.7 ± 4.9 years who had been engaged in mental labor for 10.6 ± 0.9 years. Working conditions were assessed based on indicators of work intensity. Subjects in Group 1 (n = 30) consumed a multicomponent herbal product produced using cryotechnology for 21 days; Group 2 (n = 30) served as a comparison group. Daily micronutrient intake was calculated. Blood lipid and cortisol levels were determined at baseline, on days 22, and 32.

Results. In terms of the intensity of the work process, the work is harmful (degree 3.3). When taking the product, a decrease in total cholesterol was determined (to 4.78 ± 0.63 from 5.0 ± 0.75 mmol/l (p = 0.003), an increase of 13.4% in the proportion of people with normal and a decrease of 10.0% with high cholesterol, an increase of 4.1% in the proportion of people with high high-density lipoproteins, a decrease of 11.9% in the proportion with high low-density lipoproteins; lipid atherogenicity decreased by 15.5%. In the comparison group, high high-density lipoproteins tended to decrease, low density to increase. Blood atherogenicity in the main group initially exceeded the norm in 22.2%, at the end of the observation in 6.7%, in the comparison group, respectively, in 36.7% and 53.3%. The effect on anabolic processes and stress levels was evidenced by the hormone cortisol: a decrease in 66.7% in the main group group and growth in 43.3% in the comparison group.

Research limitations. Men under 40 years of age, occupationally engaged in mental work, assessed according to the degree of harmfulness and danger as harmful level 3.3.

Conclusions. Optimization of nutrition with a natural multi-component product from plant raw materials is a method for preventing dyslipidemia and stress during long-term intense harmful mental work.
