*3.2. Nutritional Status and Metabolism of PUFAs*

Table 2 shows the FA and GPR120 concentrations in SZ and HC groups. There were no significant differences in the concentrations of AA, ALA, EPA, DHA, total omega-3, PUFAs, and GPR120 between patients and the control group.

As it was shown in Table 2, the examined groups had a similar intake of total fat, as well as omega-3 and omega-6 PUFAs. The mean intake of EPA + DHA was 88.17 mg and 34.86 mg in the SZ and HC groups, respectively, and the same number of participants from both groups (97.5%) had an intake of omega-3 FAs below the recommended daily intake (RDA; 250 mg) [22].


**Table 2.** The nutritional fatty acid status and metabolism.

<sup>1</sup> Expressed as a (DHA +EPA + ALA)/AA concentration; PUFAs—polyunsaturated fatty acids; ALA—α-linolenic acid; EPA—eicosapentaenoic acid; DHA—docosahexaenoic acid; AA—arachidonic acid; GPR120—G protein-coupled receptor 120; LA—linolenic acid; SZ—schizophrenia; HC—healthy control; SD—standard deviation; NS—not significant. The Mann–Whitney U-test was used.
