Purpose of reviewReferral to nutrition care providers in the USA such as registered dietitian nutritionists (RDNs) for medical nutrition therapy (MNT) remains low. We summarize research on the effectiveness of MNT provided by dietitians versus usual care in the management of adults with dyslipidemia. Improvements in lipids/lipoproteins were examined. If reported, blood pressure (BP), fasting blood glucose (FBG) glycated hemoglobin (A1c), body mass index (BMI), and cost outcomes were also examined.Recent findingsThe synthesis of three systematic reviews included thirty randomized controlled trials. Multiple MNT visits (3-6) provided by dietitians, compared with usual care, resulted in significant improvements in total cholesterol (mean range: - 4.64 to - 20.84 mg/dl), low-density lipoprotein cholesterol (mean range: - 1.55 to - 11.56 mg/dl), triglycerides (mean range: - 15.9 to - 32.55 mg/dl), SBP (mean range: - 4.7 to - 8.76 mm Hg), BMI (mean: - 0.4 kg/m2), and A1c (- 0.38%). Cost savings from MNT were attributed to a decrease in medication costs and improved quality of life years (QALY). Multiple MNT visits provided by dietitians compared with usual care improved lipids/lipoproteins, BP, A1c, weight status, and QALY with significant cost savings in adults with dyslipidemia and justify a universal nutrition policy for equitable access to MNT.

Human milk is universally recognized as the preferred food for infants during the first 6 mo of life because it provides not only essential and conditionally essential nutrients in necessary amounts but also other biologically active components that are instrumental in protecting, communicating important information to support, and promoting optimal development and growth in infants. Despite decades of research, however, the multifaceted impacts of human milk consumption on infant health are far from understood on a biological or physiological basis. Reasons for this lack of comprehensive knowledge of human milk functions are numerous, including the fact that milk components tend to be studied in isolation, although there is reason to believe that they interact. In addition, milk composition can vary greatly within an individual as well as within and among populations. The objective of this working group within the Breastmilk Ecology: Genesis of Infant Nutrition (BEGIN) Project was to provide an overview of human milk composition, factors impacting its variation, and how its components may function to coordinately nourish, protect, and communicate complex information to the recipient infant. Moreover, we discuss the ways whereby milk components might interact such that the benefits of an intact milk matrix are greater than the sum of its parts. We then apply several examples to illustrate how milk is better thought of as a biological system rather than a more simplistic "mixture" of independent components to synergistically support optimal infant health.

Objective: The objective of this scoping review was to examine the research question: In the adults with or without cardiometabolic risk, what is the availability of literature examining interventions to improve or maintain nutrition and physical activity-related outcomes? Sub-topics included: (1) behaviour counseling or coaching from a dietitian/nutritionist or exercise practitioner, (2) mobile applications to improve nutrition and physical activity and (3) nutritional ergogenic aids.Design: The current study is a scoping review. A literature search of the Medline Complete, CINAHL Complete, Cochrane Database of Systematic Reviews and other databases was conducted to identify articles published in the English language from January 2005 until May 2020. Data were synthesised using bubble charts and heat maps.Setting: Out-patient, community and workplace.Participants: Adults with or without cardiometabolic risk factors living in economically developed countries.Results: Searches resulted in 19 474 unique articles and 170 articles were included in this scoping review, including one guideline, thirty systematic reviews (SR), 134 randomised controlled trials and five non-randomised trials. Mobile applications (n 37) as well as ergogenic aids (n 87) have been addressed in several recent studies, including SR. While primary research has examined the effect of individual-level nutrition and physical activity counseling or coaching from a dietitian/nutritionist and/or exercise practitioner (n 48), interventions provided by these practitioners have not been recently synthesised in SR.Conclusion: SR of behaviour counseling or coaching provided by a dietitian/nutritionist and/or exercise practitioner are needed and can inform practice for practitioners working with individuals who are healthy or have cardiometabolic risk.

It is the position of the Academy of Nutrition and Dietetics and the American Council on Exercise that nutrition and physical activity interventions delivered by qualified nutrition and exercise practitioners, within their scopes of practice, can improve lifestyle behaviors and cardiometabolic risk factors for adults in the general population. Effective interventions require client-centered, evidence-based care provided by skilled practitioners using inclusive, dynamic methods, and collaboration with an interprofessional team, as appropriate. Increased access to evidence-based nutrition and physical activity interventions is necessary to improve public health and should be a target for policymakers, health care systems, and practitioners. Adults who attain a nutritious diet and adequate physical activity have improved overall health compared with their counterparts. However, most adults do not meet population recommendations. Qualified nutrition and exercise practitioners can collaborate with clients and interprofessional teams to provide nutrition and physical activity interventions and improve outcomes. However, recent guidelines have identified a need for guidance on best practices for delivering behavioral lifestyle counseling, referring to other practitioners, and improving access to disease prevention services. This Academy of Nutrition and Dietetics Position Paper aims to address common barriers for nutrition and exercise practitioners providing nutrition and physical activity interventions for adults in the general population, and best practices for overcoming these barriers. Collective action from interprofessional practitioners and implementation partners can increase access to high-quality, individualized services to prevent disease and improve health and well-being on a population level. This position was approved in July 2024 and will remain in effect until December 31, 2031., (Copyright © 2024 Academy of Nutrition and Dietetics. Published by Elsevier Inc. All rights reserved.)
