The acute effects of a DASH diet and whole food, plant-based diet on insulin requirements and related cardiometabolic markers in individuals with insulin-treated type 2 diabetes.

AIMS: There is limited research regarding insulin dosing changes following adoption of plant-based diets. We conducted a nonrandomized crossover trial utilizing two plant-based diets (Dietary Approaches to Stop Hypertension, or DASH, and Whole Food, Plant-Based, or WFPB) to assess acute changes in insulin requirements and associated markers among individuals with insulin-treated type 2 diabetes. METHODS: Participants (n = 15) enrolled in a 4-week trial with sequential, one-week phases: Baseline, DASH 1, WFPB, and DASH 2. Each diet was ad libitum and meals were provided. RESULTS: Compared to baseline, daily insulin usage was 24%, 39%, and 30% lower after DASH 1, WFPB, and DASH 2 weeks respectively (all p < 0.01). Insulin resistance (HOMA-IR) was 49% lower (p < 0.01) and the insulin sensitivity index was 38% higher (p < 0.01) at the end of the WFPB week before regressing toward baseline during DASH 2. Total, LDL, and HDL cholesterol, leptin, urinary glucose, and hsCRP decreased to a nadir at the end of the WFPB week before increasing during DASH 2. CONCLUSIONS: Adopting a DASH or WFPB diet can result in significant, rapid changes in insulin requirements, insulin sensitivity, and related markers among individuals with insulin-treated type 2 diabetes, with larger dietary changes producing larger benefits.

Physicians' Dietary Knowledge, Attitudes, and Counseling Practices: The Experience of a Single Health Care Center at Changing the Landscape for Dietary Education.

Morbidity and mortality associated with cardiovascular disease can be significantly modified through lifestyle interventions, yet there is little emphasis on nutrition and lifestyle in medical education. Improving nutrition education for future physicians would likely lead to improved preparedness to counsel patients on lifestyle interventions. An online anonymous survey of medical residents, cardiology fellows, and faculty in Internal Medicine and Cardiology was conducted at New York University Langone Health assessing basic nutritional knowledge, self-reported attitudes and practices. A total of 248 physicians responded (26.7% response rate). Nutrition knowledge was fair, but few (13.5%) felt adequately trained to discuss nutrition with patients. A majority (78.4%) agreed that additional training in nutrition would allow them to provide better clinical care. Based on survey responses, a dedicated continuing medical education (CME) conference was developed to improve knowledge and lifestyle counseling skills of healthcare providers. In postconference evaluations, attendees reported improved knowledge of evidence-based lifestyle interventions. Most noted that they would prescribe a Mediterranean or plant-based diet and would make changes to their practice based on the conference. An annual CME conference on diet and lifestyle can effectively help interested providers overcome barriers to lifestyle change in clinical practice through improved nutrition knowledge.

Strategies to Fill the Gaps in Nutrition Education for Health Professionals through Continuing Medical Education.

PURPOSE OF REVIEW: Recent studies have documented that diet quality in the US is poor and linked to higher rates of cardiovascular disease (CVD), other non-communicable diseases, and total mortality. As a result, nutrition counseling in clinical practice is an evidence-based strategy endorsed by numerous stakeholders. However, medical nutrition education (MNE) in the US has been inadequate, and physician knowledge, competencies, and practices related to diet counseling have been documented to be insufficient. National scientific meetings and conferences offer opportunities to translate new scientific evidence, guidelines, and competencies to clinicians in attendance and to publicize this evidence widely. This review assessed the adequacy of, and trends in, nutrition education provided at recent major US scientific meetings that offer continuing medical education (CME), with a focus on CVD-related conferences. RECENT FINDINGS: The authors found no reviews that have assessed the scope and type of nutrition-related educational programming at major conferences. We therefore investigated nutrition-related programming at CVD-related CME conferences in the US from 2013 to 2018. National scientific CVD-related conferences in the USA have offered variable amounts of programming related to practical applications of nutrition science. We did not observe an increase in nutrition-related offerings, despite the increase in diet-related diseases and the growing evidence base for the role of nutrition in the prevention and management of chronic disease. Increasing nutrition-related CME programming at national scientific meetings can lead to greater translation of nutrition evidence to patients by healthcare providers and improved health outcomes in the population.
