Low-grade inflammation adversely influences metabolism and cardiovascular prognosis, nevertheless increased intake of fruits and vegetables has rarely been studied in this context. Objective: In a prospective controlled study, the effect on C-reactive protein (CRP) levels was assessed. Methodology: Sixty consecutive women undergoing cosmetic abdominal surgery were instructed to consume six servings each of fruits and vegetables during the first postoperative month. Detailed 24h interviewer-administered dietary recall was conducted at baseline and at the end of the study, with weekly returns to monitor unscheduled dietary changes and compliance with the protocol. Variance (ANOVA) and covariance (ANCOVA) were evaluated to confirm significance and minimize confounding variables. Results: No differences concerning age (42.2 ± 5.3 vs 41.1 ± 6.0 years) or BMI (25.5± 3.1 vs 25.0± 3.0 kg/m²) occurred. Ingestion of fruits increased to approximately 5.2 vs 3.9 and of vegetables 5.9 vs 3.4 servings/ day, respectively. CRP decreased more conspicuously in the treated group (P=0.028), and correlation between vitamin C input and CRP in supplemented participants was demonstrated (P=0.014). Conclusions: Higher intake of antioxidant foods was feasible, and an antiinflammaotory effect occurred. Further studies with longer administration and follow-up period are recommended.Inflamación subclínica influencia adversamiente el metabolismo y el pronóstico cardiovascular, pero ingestión elevada de vegetales y frutas há sido pocas veces investigada en este contexto. Objetivo: En un estúdio prospectivo y controlado, el impacto sobre la proteina C-reactiva fue determinado. Metodología: Sesenta pacientes consecutivas sometidas a cirugía cosmética abdominal fueron instruídas a consumir seis porciones diárias de frutas y mais seis de vegetales, en el primero més de postoperatório. Un recordatório alimentar detallado registrado por dietista fue conducido inicialmiente y al cabo del estúdio, con retornos semanales para monitorar aderéncia y cámbios eventuales de la dieta. Análisis de variáncia (ANOVA) y covariáncia (ANCOVA) fueron realizadas para evaluar resultados y minimizar variables de confusión. Conclusiones: Un consumo mas alto de alimientos antioxidantes fue posible, y una respuesta antiinflamatória fue documentada. Estúdios adicionales com suministración y seguimiento mas prolongados son recomendados.
