Greater protein quality of an egg breakfast may be inadequate to induce satiety during weight loss, compared with a cereal breakfast of equal protein quantity.

We compared the effects of consuming egg-breakfast of superior protein quality to cereal-breakfast of similar energy density and protein quantity, but lower protein quality. Two, two-week randomised crossover clinical trials included 30 otherwise healthy women with overweight or obesity. Subjects received counselling to follow a reduced-calorie diet. Under supervision, participants consumed either breakfast for one-week then crossed over to the opposite breakfast. Experiment-1 outcome variables included post-breakfast appetite hormones, glucose and insulin, subjective markers of satiety and energy intake at lunch and dinner. In Experiment-2, an appealing food (brownies) was included in lunch. Following the breakfasts, Experiment-1 showed no significant differences in outcome variables. In Experiment-2, the egg-breakfast increased fullness (p = 0.038), but lunch-time energy intake was not different. If these findings apply to other breakfasts, it suggests that in comparing two breakfasts with similar protein quantity, the greater protein quality of a breakfast may not be adequate to induce satiety.

A short, attribution theory-based video intervention does not reduce weight bias in a nationally representative sample of registered dietitians: a randomized trial.

BACKGROUND/OBJECTIVES: Weight bias among registered dietitians (RDs) is a concern and effective interventions to reduce weight bias are sparse. Our objective was to determine if a short, attribution theory-based online video intervention would reduce weight bias in RDs. SUBJECTS/METHODS: Dietitians from a nationally representative sample were recruited for a randomized, parallel-arm study with online surveys at pre-, post-intervention and 1-month follow-up. One hundred and forty-seven RDs who watched one of three videos embedded in an online survey from June to August 2019 were considered for the analysis. RDs were randomized to watch either the intervention, positive control, or negative control video. The primary outcome was the change in the "blame" component of the Anti-Fat Attitude Test (AFAT) from pre-to immediate post-intervention. Differences in changes in AFAT and Implicit Association Test (IAT) scores across treatment groups were assessed via linear models; multiple imputation were performed for missing data. RESULTS: Baseline demographics, AFAT and IAT scores of the 147 participants who watched a video were not significantly different between the study groups (p > 0.05). The intervention group's AFAT-blame score reduced by an average of 0.05 between pre- and immediate post-intervention but was not statistically significant (p = 0.76, confidence intervals (CI) = -0.40, 0.30). Furthermore, there were no significant changes for AFAT-social, AFAT-physical subscores, and IAT within or between groups between pre- and immediate post-intervention (p > 0.05). Due to high attrition rates, the changes at 1-month follow-up are not reported. CONCLUSIONS: This study was the first to explore the effectiveness of an online video intervention to reduce weight bias in RDs. This study was unable to detect a significant impact of a short, attribution theory-based video intervention on weight bias in practicing RDs and future larger studies are needed to confirm our findings.

Perceptions and preferences for environmentally sustainable food and associated factors: a cross-sectional analysis of a nationally representative survey of United States consumers.

BACKGROUND: Consumers are increasingly interested in environmentally sustainable dietary patterns. However, specific signals (e.g., language, labels, logos, or packaging) American consumers use to identify environmentally sustainable products are yet to be explored. OBJECTIVES: To determine perception and preferences for environmentally sustainable food and associated health and demographic factors associated with consumers' use of signals for environmentally sustainable food products in a nationally representative survey of United States consumers. METHODS: Repeated cross-sectional data were collected for the 2019 and 2020 annual online Food and Health Survey by the International Food Information Council. Three questions were analyzed: 1) the stated importance of environmentally sustainable food products, 2) signals consumers use to identify environmentally sustainable food/beverage products, and 3) the impact of environmental sustainability on food/beverage purchase decisions. Questions 2 and 3 were asked only from participants who stated environmental sustainability is important in question 1. Options provided for signals for environmentally sustainable products were recyclable packaging, minimal packaging, labeled organic, labeled locally grown, labeled sustainably sourced, and labeled non-genetically modified organisms (GMOs, not bioengineered). Poisson regression and logistic regressions were performed to assess associations. RESULTS: Of 1905 completers, 1059 (55.6%) answered that it was somewhat or very important that food products purchased/consumed were environmentally sustainable. Of those, 94% used ≥1 of the 6 signals to determine environmental sustainability when shopping. Some signals were selected despite little association with environmental sustainability (e.g., locally grown and non-GMO/not bioengineered). The number of signals consumers used was associated with education, race/ethnicity, health status, and the level of impact they reported that sustainability plays in their decisions. Associations between consumer characteristics and the use of different signals for environmental sustainability were heterogeneous. CONCLUSIONS: Even among consumers who value environmental sustainability in food products, specific signals used by different respondents varied across demographics and health characteristics.

Weight Bias Among Nutrition and Dietetics Students in a Ghanaian Public University.

OBJECTIVES: To measure the internal consistency reliability of 3 weight bias scales among nutrition and dietetics students enrolled at a public university in Ghana and to use the Fat Phobia Scale (FPS) to determine the prevalence of weight bias and the differences in gender and body mass index. DESIGN: Online survey gathered self-reported height, weight, and demographic data. Explicit weight bias was assessed using validated FPS, Beliefs About Obese People, and Attitudes Toward Obese Persons scales. PARTICIPANTS: Sample of 172 students. MAIN OUTCOME MEASURES: Prevalence of weight bias. ANALYSIS: Cronbach α reliability test was used to measure the internal consistency of scales. The prevalence of weight bias was expressed as a percentage. Independent t tests and analysis of variance were used to explore differences in gender and weight categories. RESULTS: The reliability scores for FPS, Beliefs About Obese People, and Attitudes Toward Obese Persons scales were 0.92, 0.51, and 0.38, respectively. About 53% of participants expressed weight bias. A significant difference was observed for weight bias between overweight and obese participants, with participants with obesity showing greater weight bias (P = 0.03). CONCLUSION AND IMPLICATIONS: Fat Phobia Scale (most reliable) identified more than half of the students had a negative attitude toward obesity. Weight bias training within this population may improve attitudes toward obesity.

The Impostor Phenomenon in the Nutrition and Dietetics Profession: An Online Cross-Sectional Survey.

The impostor phenomenon (IP) (also known as impostor syndrome) describes high-achieving individuals who, despite their objective successes, fail to internalize their accomplishments and have persistent self-doubt and fear of being exposed as a fraud or impostor. This study aimed to assess the prevalence and predictors of IP within a sample of nutrition and dietetics students and practitioners. An online cross-sectional survey was conducted and utilized a non-random, convenience sampling approach. A total of 1015 students, dietetic interns, and currently practicing and retired registered dietitian nutritionists and nutrition and dietetic technicians registered provided complete responses. IP was assessed with the Clance Impostor Phenomenon Scale (CIPS). Self-reported job satisfaction and well-being were assessed using validated scales. Average CIPS score was 66.0 ± 16.3 (range 22−99), and higher scores indicate more frequent or severe IP experiences. Frequent or intense IP was reported by 64% of survey respondents (n = 655). Older age, greater educational attainment and professional level, and membership in Academy of Nutrition and Dietetics groups were associated with lower IP scores. Greater social media use was associated with higher IP scores. Job satisfaction and overall well-being were inversely correlated with IP (p < 0.001). Findings suggest that IP experiences were common among a majority of nutrition and dietetics students and practitioners surveyed. Additional research and development of preventative strategies and interventions is needed.

You Are Not an Impostor: The Registered Dietitian Nutritionist and Impostor Phenomenon.

Impostor phenomenon (IP) interferes with the desire for taking advantage of career opportunities and pursuing career advancement. There is robust literature describing the effects of IP in other health care professions, yet an absence of research exists on IP within the nutrition and dietetics profession. This perspective will explore why nutrition and dietetics professionals may experience IP, specify what might be done to mitigate the negative effects of IP, and describe future research directions. Impostorism is an understudied phenomenon that could have significant implications for the profession of nutrition and dietetics on an individual and systemic level.

Culinary efficacy: an exploratory study of skills, confidence, and healthy cooking competencies among university students.

AIMS: This study was conducted to determine whether a group of college-age students in New Jersey, USA, had the requisite culinary skills, knowledge, and confidence to take personal control of their meal planning and production. The long-term threat to the public health systems posed by high rates of obesity among young adults in higher education institutions has garnered widespread attention across the world. Studies have shown that assuming personal responsibility over preparing and consuming food can play a key role in addressing the problem of poor nutrient intakes. METHODS: Focus groups were conducted with students (N = 24) who fit the eligibility criteria of not having a university meal plan, and living independently at the time of the study (not with family members). The sessions were recorded, transcribed, and then coded into themes. Two trained research assistants tested the results and inter-rater reliability was confirmed. RESULTS: Content analysis revealed three major themes: Health Perceptions, Life influences, and Barriers to Cooking and Eating Healthy. The students' comments indicated that while they had a basic knowledge of the key principles of eating a balanced diet, it may not have necessarily translated into actual food choices and cooking practices. Several students reported an overreliance on processed and prepared foods, and they consumed few fruits and vegetables. CONCLUSIONS: Factors such as lack of culinary knowledge and skill, financial instability, inadequate access to healthy food options, and other time/lifestyle constraints may have played a significant role in limiting their ability to prepare and consume healthy meals. The findings of this study highlight the importance of designing programmes with effective strategies to motivate and encourage college students to improve their food behaviours and practices.
