COPD: Medical Nutrition Therapy (2019)
The provision of medical nutrition therapy (MNT) is limited to RDNs. Registered dietitian nutritionist (RDN) is a credential granted to nutrition professionals in the United States, who have met all requirements for credentialing through the Commission on Dietetic Registration (CDR), the credentialing agency of the Academy of Nutrition and Dietetics.
The term “RD/RDN (or international equivalent)” is used on the Evidence Analysis Library (EAL) to allow for studies conducted outside the U.S. to be considered in evaluating the effectiveness of MNT.
To qualify as “international equivalent” for international studies, the country of study’s origin should be a member of International Confederation of Dietetic Associations (ICDA). The credentials for international studies should represent the recognized credentials as stated on ICDA’s website (http://www.internationaldietetics.org/) for that particular country. In addition, international equivalents include nutrition professionals in countries with reciprocity agreements with the CDR (https://www.cdrnet.org/certifications/registration-eligibility-requirements-for-dietitians).

What is the effectiveness of medical nutrition therapy as part of a multidisciplinary program on body composition and lung function outcomes in adults with COPD?-
Conclusion
As part of a multidisciplinary program, medical nutrition therapy (MNT) intervention provided by a registered dietitian nutritionist (RDN) (or international equivalent) was effective in improving body composition outcomes in adults with COPD. Findings for certain lung function parameters (including forced vital capacity and maximum inspiratory mouth pressure) were mixed. No improvements, nor negative outcomes were found in other lung function parameters measured.

What is the effectiveness of medical nutrition therapy as part of a multidisciplinary program on functional status, exacerbations, systemic inflammation, respiratory symptoms, hospital costs and admissions outcomes in adults with COPD?-
Conclusion
As part of a multi-disciplinary program, medical nutrition therapy (MNT) intervention provided by a registered dietitian nutritionist (RDN) (or international equivalent) was effective in improving functional status, dyspnea scores, reducing hospital admissions and lowering hospital admissions costs in adults with COPD. No improvements nor negative outcomes were found in the frequency or severity of exacerbations or inflammatory markers.
