A recently published narrative review summarizes current research on the effectiveness of MNT provided by RDNs compared to usual care in the management of adult dyslipidemia. Improvements in lipid profile were examined as the primary outcome of interest. Other outcomes of interest included blood pressure, fasting blood glucose (FBG) glycated hemoglobin (A1c), body mass index and cost.
Synthesis of three systematic reviews included 30 randomized controlled trials. Multiple MNT visits (three to six) provided by RDNs, compared with usual care, resulted in significant improvements in total cholesterol, low-density lipoprotein cholesterol, triglycerides, systolic blood pressure, BMI and A1c. Cost savings from MNT were attributed to a decrease in medication costs and improved quality of life years.
Patient-centered treatment goals can be achieved when MNT provided by an RDN is combined with a pharmacological approach. Multiple MNT visits provided by RDNs, compared with usual care, improved lipids/lipoproteins, blood pressure, A1c, BMI and quality of life years, with significant cost savings in adults with dyslipidemia. These results justify a universal nutrition policy for equitable access to MNT. Learn more in this free, open-access article published in Current Atherosclerosis Reports.
