Objective. Medical Nutrition Therapy (MNT) is important in the treatment and regulation of diabetic patients. In this study, it was aimed to evaluate the effects of medical nutrition therapy on Pentraxin-3, hsCRP and body composition analysis in Type 2 diabetes patients (DM). Methods. This study included 160 individuals who were admitted and diagnosed with Type 2 DM. Laboratory, clinical, anthropometric and body composition parameters were obtained 3 months after baseline evaluation of the patients and the MNT was given by the dietitian. Results. After 3 months MNT, weight, body mass index, waist circumference, body fat weight, body fat ratio and visceral fat area (p<0.001), glucose (p<0.001), insulin (p=0.033), HOMA index (p=0.004), HbA1c (p<0.001), total cholesterol (p=0.001), LDL (p=0.008), ALT (p<0.001) and hsCRP (p<0.001) levels were significantly lower than they were before MNT. There wasn’t significant difference in triglyceride (p=0.509), HDL (p=0.079), Pentraxin-3 (p=0.706) levels and waist-to-hip ratio (p=0.802). The level of Framingham risk score after MNT was significantly lower (p<0.001). Conclusion. In this study, it was cocluded that MNT, applied to patients with Type 2 DM decreased cardiovascular risk and inflammation, contributed to the maintenance of glycemic control, and a significantly improved the body composition.
