Abstract
BACKGROUND/ OBJECTIVES:Weight loss through a low-calorie diet (LCD) could improve low-grade inflammation evident in the obese state. Few studies have evaluated the effect of the mixed nuts consumption in the context of a LCD on inflammatory biomarkers. This study compared the effects of a nut-enriched LCD (NELCD) with a nut-free LCD (NFLCD) on body weight and inflammatory markers in overweight or obese coronary artery disease (CAD) patients. SUBJECTS/ METHOD: In this randomized controlled parallel trial, patients with stable CAD of both genders were randomly allocated to 8-week NELCD or NFLCD. Body weight, plasma C-reactive protein (CRP), interleukin-6 (IL-6), interleukin 10 (IL-10), intercellular adhesion molecule-1 (ICAM-1), and monocyte chemoattractant protein (MCP-1) were assessed at baseline and 8 weeks. RESULTS: Overall, 67 patients (aged 58.8 ± 7.4 years; BMI 30.9 ± 3.9 kg/m2) completed the study. Participants in both groups lost weight to a comparable extent. Patients in the NELCD group showed a decrease in ICAM-1 (p = 0.04) and IL-6 (p = 0.02) concentrations compared to NFLCD group. No significant difference in concentrations of MCP-1, IL-10, or CRP was observed between diet groups. CONCLUSIONS: Nuts are healthy energy-dense foods that if included in controlled amounts in a weight management program can still result in weight reduction and may improve some plasma concentration of inflammatory factors, such as ICAM-1 and IL-6.
