Dietary Inflammatory Index and Cardiometabolic Risk Parameters in Overweight and Sedentary Subjects.

Nutrition has been established as a relevant factor in the development of cardiovascular disease (CVD). We aimed to investigate the relationship between the dietary inflammatory index (DII) and cardiometabolic risk parameters in a cohort of 90 overweight and sedentary adults from Bogotá, Colombia. A 24-h dietary record was used to calculate the DII. Body composition variables, flow-mediated dilation (FMD), pulse wave velocity (PWV), lipid profile, glucose, glycosylated hemoglobin (Hb1Ac), and blood pressure were measured and a cardiometabolic risk score (MetScore) was calculated. A lower DII score (anti-inflammatory diet) was significantly associated with higher high-density lipoprotein-cholesterol (HDL-C) and FMD, and lower Hb1Ac and MetScore ( < 0.05). A lower DII score was inversely correlated with plasma triglyceride levels ( = -0.354, < 0.05), glucose ( = -0.422, < 0.05), MetScore ( = -0.228, < 0.05), and PWV ( = -0.437, < 0.05), and positively with FMD ( = 0.261, < 0.05). In contrast, a higher DII score (pro-inflammatory diet) showed a positive relationship with MetScore ( = 0.410, < 0.05) and a negative relationship with FMD ( = -0.233, < 0.05). An increased inflammatory potential of diet was inversely associated with an improved cardiometabolic profile, suggesting the importance of promoting anti-inflammatory diets as an effective strategy for preventing CVD.
