We observed that in adolescents with PCOS, grouped according to the body weight phenotype, there were inverse correlations between the concentration of inflammatory markers and redox balance and the supply of proteins, including plant proteins, carbohydrates, and fibres, and a positive correlation between the consumption of cholesterol and the inflammatory marker C-Reactive Protein (CRP)8. The gene discussed is CRP; the disease is polycystic ovary syndrome.
