CRP and depressive symptom measurement: Further food sources of hippurate, retinol, lysophosphatidic acid, mannitol/sorbitol and lecithin including fresh fruits (β = −0.04, P-value = 0), vegetables (β = −0.02, P-value = 1.2 × 10−199), retinol intake from food (β = 6.0 × 10−05, P-value = 6.7 × 10−04), eggs (β = 0.04, P-value = 7.9 × 10−07) and artificial sweetener use (β = 0.02, P-value = 0.012) were all significantly associated with CRP and consistent with the findings of depression (Supplementary Table 9).
