“…Therefore, strategies with the aim of changing older peoples' choice towards healthier food can be highly promoted. Currently, dietary education, meal service and multicomponent strategies have been applied to promote older people's healthy eating (Zhou et al, 2018). For instance, nutritional dietary education has shown positive outcomes on older people's dietary behaviour by raising their understanding and knowledge regarding healthy eating (Bandayrel & Wong, 2011).…”

A quasi-experimental study was designed to promote novel plant-based dishes using the nudging strategy 'dish of the day' among older consumers in Denmark, France, Italy and the United Kingdom. Participants were presented with three dish options: veggie balls, meatballs and fish cakes. In the intervention situation, participants were informed that the 'dish of the day' was the novel plant-based 'veggie balls'. Thereafter, participants were asked to choose one of three dishes to intake and then fill a questionnaire. No statistically significant difference in dish choice was found between the control group and intervention group in the four countries. Males were less likely to choose the plant-based dish when compared with the females. Participants from the United Kingdom and Denmark were more likely to choose the plant-based dish when compared with participants from France. High scores of security dimension from the Human Value Scale was negatively associated with choice of plant-based dish, while high scores of the sensory dimension from Food Choice Questionnaire and high scores of the universalism dimension from Human Values Scale were positively related to the choice of the plant-based dish. The 'dish of the day' nudging approach did not influence older people's plant-based dish choice. Gender, country, and dimensions of sensory, universalism and security were critical factors influencing an older people's plant-based food choice.

“…Cardiovascular disease afflicts ∼122 million Americans and causes ∼840,000 deaths each year ( 40 ). Many of these diseases disproportionately affect older Americans, and as our nation's demographics shift toward an aging population, the burden of diet-related ailments on society will accelerate ( 41 , 42 ). In short, more Americans are sick or suffer from major medical conditions than are healthy, and much of this is related to diet-related illness.…”

Background The US faces remarkable food and nutrition challenges. A new federal effort to strengthen and coordinate nutrition research could rapidly generate the evidence base needed to address these multiple national challenges. However, the relevant characteristics of such an effort have been uncertain. Objectives Our aim was to provide an objective, informative summary of 1) the mounting diet-related health burdens facing our nation and corresponding economic, health equity, national security, and sustainability implications; 2) the current federal nutrition research landscape and existing mechanisms for its coordination; 3) the opportunities for and potential impact of new fundamental, clinical, public health, food and agricultural, and translational scientific discoveries; and 4) the various options for further strengthening and coordinating federal nutrition research, including corresponding advantages, disadvantages, and potential executive and legislative considerations. Methods We reviewed government and other published documents on federal nutrition research; held various discussions with expert groups, advocacy organizations, and scientific societies; and held in-person or phone meetings with >50 federal staff in executive and legislative roles, as well as with a variety of other stakeholders in academic, industry, and nongovernment organizations. Results Stark national nutrition challenges were identified. More Americans are sick than are healthy, largely from rising diet-related illnesses. These conditions create tremendous strains on productivity, health care costs, health disparities, government budgets, US economic competitiveness, and military readiness. The coronavirus disease 2019 (COVID-19) outbreak has further laid bare these strains, including food insecurity, major diet-related comorbidities for poor outcomes from COVID-19 such as diabetes, hypertension, and obesity, and insufficient surveillance on and coordination of our food system. More than 10 federal departments and agencies currently invest in critical nutrition research, yet with relatively flat investments over several decades. Coordination also remains suboptimal, documented by multiple governmental reports over 50 years. Greater harmonization and expansion of federal investment in nutrition science, not a silo-ing or rearrangement of existing investments, has tremendous potential to generate new discoveries to improve and sustain the health of all Americans. Two identified key strategies to achieve this were as follows: 1) a new authority for robust cross-governmental coordination of nutrition research and other nutrition-related policy and 2) strengthened authority, investment, and coordination for nutrition research within the NIH. These strategies were found to be complementary, together catalyzing important new science, partnerships, coordination, and returns on investment. Additional complementary actions to accelerate federal nutrition research were identified at the USDA. Conclusions The need and opportunities for strengthened federal nutrition research are clear, with specific identified options to help create the new leadership, strategic planning, coordination, and investment the nation requires to address the multiple nutrition-related challenges and grasp the opportunities before us.

Background Advances in voice technology have raised new possibilities for apps related to daily health maintenance. However, the usability of such technologies for older users remains unclear and requires further investigation. Objective We designed and evaluated two innovative mobile voice-added apps for food intake reporting, namely voice-only reporting (VOR) and voice-button reporting (VBR). Each app features a unique interactive procedure for reporting food intake. With VOR, users verbally report the main contents of each dish, while VBR provides both voice and existing touch screen inputs for food intake reporting. The relative usability of the two apps was assessed through the metrics of accuracy, efficiency, and user perception. Methods The two mobile apps were compared in a head-to-head parallel randomized trial evaluation. A group of 57 adults aged 60-90 years (12 male and 45 female participants) was recruited from a retirement community and randomized into two experimental groups, that is, VOR (n=30) and VBR (n=27) groups. Both groups were tested using the same set of 17 food items including dishes and beverages selected and allocated to present distinct breakfast, lunch, and dinner meals. All participants used a 7-inch tablet computer for the test. The resulting data were analyzed to evaluate reporting accuracy and time efficiency, and the system usability scale (SUS) was used to measure user perception. Results For eight error types identified in the experiment, the VBR group participants were significantly (P<.001) more error prone owing to the required use of button-tapping actions. The highest error rates in the VOR group were related to incomprehensible reporting speech (28/420, 6.7%), while the highest error rates in the VBR group were related to failure to make required button taps (39/378, 10.3%). The VOR group required significantly (P<.001) less time to complete food reporting. The overall subjective reactions of the two groups based on the SUS surpassed the benchmark and were not significantly different (P=.20). Conclusions Experimental results showed that VOR outperformed VBR, suggesting that voice-only food input reporting is preferable for elderly users. Voice-added apps offer a potential mechanism for the self-management of dietary intake by elderly users. Our study contributes an evidence-based evaluation of prototype design and selection under a user-centered design model. The results provide a useful reference for selecting optimal user interaction design.
