Overview

Cross-sectional study evaluates Mediterranean diet impact on oxidative stress and body composition in ICU survivors with post-COVID-19 symptoms, suggesting dietary importance.

Key Points

  • This research aims to assess the link between adherence to the Mediterranean diet and oxidative stress markers in ICU survivors post-COVID-19. Additionally, it explores the relationship with body composition and inflammatory markers.
  • Cross-sectional study conducted with 123 adult ICU survivors who experienced post-COVID-19 condition.
  • Diet adherence was evaluated using the Mediterranean Diet Adherence Screener (MEDAS) and body composition assessed through DXA.
  • Biomarkers including protein carbonyls, TBARS, glutathione, CRP, albumin, and IL-6 were measured.
  • Median MEDAS score was 4 (IQR 2–5), indicating low adherence to the Mediterranean diet.
  • Lower adherence correlated with higher glutathione levels (p = 0.04) and no significant differences in pro-oxidant markers.
  • Higher levels of sulfhydryl groups linked to lower body fat, increased skeletal muscle mass, and reduced CRP and IL-6.
