Brief summary
Analysis of the effect of dietary intervention based on increased polyunsaturated fatty acid intake on health. Specifically changes in blood lipid profile, as well as proteomic and metabolomic profiles of healthy adults will be analyzed.
Interventions
Assumptions of nutritional intervention: in a randomized manner volunteers will be assigned to one of two groups: a control group which will receive general nutritional recommendations, based on the Polish nutrition pyramid, and the intervention group which will receive nutritional recommendations, based on the Polish nutrition pyramid and will consume at least 4 tablespoons of olive oil or 30 grams of nuts every day for 12 weeks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Nutrient intake | 12 weeks | Nutrient intake (3-day food records) |
| Concentrations of lipoproteins and glucose | 12 weeks | Serum concentrations of lipoproteins and glucose at baseline and after the intervention \[mg/dl\] |
| Proteomic analysis of plasma | 12 weeks | The aim is to identify biomarkers in the blood and to determine the differences between people from the control and the intervention group |
| Metabolite concentrations in plasma | 12 weeks | Metabolite concentrations in plasma samples are measured by high resolution mass spectrometry at baseline and after the intervention |
Secondary
