Changes in food and nutrient intakes in Korean adults before and during the COVID-19 pandemic: data from the 2011-2020 Korea National Health and Nutrition Examination Survey.

OBJECTIVES: This study was to examine the changes in dietary habits and food and nutrient intakes between before (2019) and during (2020) the coronavirus disease 2019 (COVID-19) pandemic from the Korea National Health and Nutrition Examination Survey (KNHANES). METHODS: A total of 54,995 participants aged ≥19 years who participated in the 2011-2020 KNHANES were included. The 10-year trend (2011-2020) and differences between 2019 and 2020 for dietary habits and food and nutrient intakes were estimated using SAS. RESULTS: In the past 10 years (2011-2020), the dietary habits (increase in skipping meals and eating out), food intake (increase in meats and decrease in fruits and vegetables), and nutrient intake (increase in fat and decrease in sodium) in adults have changed. When comparing between 2019 and 2020, there were 4.6%p decrease in the eating out more than once a day. On the other hand, there were no significant differences in the intakes of food, energy and most of nutrients between 2019 and 2020, except for the proportion of energy intake from fat (1.0%p increase) and carbohydrate (1.0%p decrease). CONCLUSIONS: Although a change in dietary habits from before to during the COVID-19 pandemic was observed, food and nutrient intakes have not deteriorated markedly and appear similar to the trends in the past 10 years. Throughout the COVID-19 pandemic, it is necessary to monitor the effects of changes in dietary habits on health as well as food and nutrient intakes.

Physical activity, food and social distancing of people with down syndrome during the COVID-19 pandemic / Atividade física, alimentação e distanciamento social de pessoas com síndrome de down durante a pandemia da COVID-19 / Actividad física, alimentación y distanciamiento social de personas con síndrome de down durante la pandemia COVID-19

Esta pesquisa tem por objetivo analisar o distanciamento social, o nível de atividade física e a alimentação de pessoas com síndrome de Down durante a pandemia de COVID-19. Participaram do estudo 24 pessoas por meio de um formulário eletrônico com 45 questões fechadas. Entre os resultados encontrados verificou-se que após uma média de 69,87 dias do início das medidas de afastamento e redução de convívio para controle da pandemia houve diminuição do nível de atividade física e da qualidade da alimentação, bem como o aumento do índice de massa corporal. Verificou-se que as pessoas com síndrome de Down desenvolveram, em distanciamento social, características que po-dem agravar um possível quadro de COVID-19 e a maioria tem contato com pessoas que não estão reduzindo a interação com outras pessoas. Concluiu-se que ações voltadas para as pessoas com síndrome de Down são urgentes para que essas não fiquem ainda mais expostas às consequências da pandemia (AU0.

This research aims to analyze the social distancing, the level of physical activity and the diet of people with Down syndrome, during the COVID-19 pandemic. 24 people participated in this study by means of an electronic form with 45 closed questions. Among the results found, it was found that after an average of 69.87 days of distancing, there was a decrease in the level of physical activity and quality of food, as well as an increase in the body mass index. It was found that people with Down syndrome have characteristics that can aggravate a possible COVID-19 condition and most have contact with people who are not in distancing. It was concluded that actions are urgently needed so that people with Down syndrome are not even more exposed in this pandemic moment (AU).

Reframing the local-global food systems debate through a resilience lens.

Despite the growing knowledge that food system solutions should account for interactions and drivers across scales, broader societal debate on how to solve food system challenges is often focused on two dichotomous perspectives and associated solutions: either more localized food systems or greater global coordination of food systems. The debate has found problematic expressions in contemporary challenges, prompting us to revisit the role that resilience thinking can play when faced with complex crises that increase uncertainty. Here we identify four 'aching points' facing food systems that are central points of tension in the local-global debate. We apply the seven principles of resilience to these aching points to reframe the solution space to one that embeds resilience into food systems' management and governance at all scales, supporting transformative change towards sustainable food systems.

Scoping review protocol exploring the relationship between food insecurity, mental health and diet intake among adolescents across the globe.

INTRODUCTION: Studies, exploring the effect of food insecurity on physical and mental health, have shown that food insecurity is associated with lower self-reports of physical and mental health. With the COVID-19 pandemic, food insecurity has increased leading to higher risks of poor mental health. Despite evidence of the negative implications of food insecurity on mental health, there is a paucity of research on these variables for adolescents specifically. The current evidence shows there is a gap in adolescent centred research linking mental health and food insecurity globally. Adolescence is a crucial period of development where habits, nutritional inadequacies linked to food insecurity and mental health problems formed due to these inadequacies can be conveyed into adulthood. The aim of this study is to systematically scope the literature exploring the relationship between mental health, food (in)security and/or diet intake of adolescents. METHODS: This review will be guided by Arksey and O'Malley's extended framework. The search strategy was developed by two of the authors and will be used to search literature from January 2012 to December 2022 in PubMed, Academic search complete, PsychARTICLES, Google, ScienceDirect, Scopus and Web of science core collection. Searching published and unpublished literature will be done in the chosen databases. References used in included literature will be reviewed for additional studies/sources. Articles will be assessed for eligibility by two reviewers, and any discrepancies reviewed by a third reviewer. The inclusion and exclusion criteria will be used for screening. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagram will be used to document the selection process. A narrative summary and descriptive analysis will be used to summarise and report the extracted data. ETHICS AND DISSEMINATION: Approval for this study has been granted by the University of the Western Cape Biomedical Research Ethics Committee (BM21/8/3). Strict measures will be followed to ensure methodological rigour.

Cannabis companies and the sponsorship of scientific research: A cross-sectional Canadian case study.

Corporations across sectors engage in the conduct, sponsorship, and dissemination of scientific research. Industry sponsorship of research, however, is associated with research agendas, outcomes, and conclusions that are favourable to the sponsor. The legalization of cannabis in Canada provides a useful case study to understand the nature and extent of the nascent cannabis industry's involvement in the production of scientific evidence as well as broader impacts on equity-oriented research agendas. We conducted a cross-sectional, descriptive, meta-research study to describe the characteristics of research that reports funding from, or author conflicts of interest with, Canadian cannabis companies. From May to August 2021, we sampled licensed, prominent Canadian cannabis companies, identified their subsidiaries, and searched each company name in the PubMed conflict of interest statement search interface. Authors of included articles disclosed research support from, or conflicts of interest with, Canadian cannabis companies. We included 156 articles: 82% included at least one author with a conflict of interest and 1/3 reported study support from a Canadian cannabis company. More than half of the sampled articles were not cannabis focused, however, a cannabis company was listed amongst other biomedical companies in the author disclosure statement. For articles with a cannabis focus, prevalent topics included cannabis as a treatment for a range of conditions (15/72, 21%), particularly chronic pain (6/72, 8%); as a tool in harm reduction related to other substance use (10/72, 14%); product safety (10/72, 14%); and preclinical animal studies (6/72, 8%). Demographics were underreported in empirical studies with human participants, but most included adults (76/84, 90%) and, where reported, predominantly white (32/39, 82%) and male (49/83, 59%) participants. The cannabis company-funded studies included people who used drugs (37%) and people prescribed medical cannabis (22%). Canadian cannabis companies may be analogous to peer industries such as pharmaceuticals, alcohol, tobacco, and food in the following three ways: sponsoring research related to product development, expanding indications of use, and supporting key opinion leaders. Given the recent legalization of cannabis in Canada, there is ample opportunity to create a policy climate that can mitigate the harms of criminalization as well as impacts of the "funding effect" on research integrity, research agendas, and the evidence base available for decision-making, while promoting high-priority and equity-oriented independent research.

Opportunities to Promote Food and Nutrition Security as the Federal Public Health Emergency Ends.

This JAMA Forum discusses key changes to the social safety net after the COVID-19 public health emergency ends and provides information regarding the ways health care professionals can support individuals experiencing food and nutrition security.

Perspective: Multiomics and Machine Learning Help Unleash the Alternative Food Potential of Microalgae.

Food security has become a pressing issue in the modern world. The ever-increasing world population, ongoing COVID-19 pandemic, and political conflicts together with climate change issues make the problem very challenging. Therefore, fundamental changes to the current food system and new sources of alternative food are required. Recently, the exploration of alternative food sources has been supported by numerous governmental and research organizations, as well as by small and large commercial ventures. Microalgae are gaining momentum as an effective source of alternative laboratory-based nutritional proteins as they are easy to grow under variable environmental conditions, with the added advantage of absorbing carbon dioxide. Despite their attractiveness, the utilization of microalgae faces several practical limitations. Here, we discuss both the potential and challenges of microalgae in food sustainability and their possible long-term contribution to the circular economy of converting food waste into feed via modern methods. We also argue that systems biology and artificial intelligence can play a role in overcoming some of the challenges and limitations; through data-guided metabolic flux optimization, and by systematically increasing the growth of the microalgae strains without negative outcomes, such as toxicity. This requires microalgae databases rich in omics data and further developments on its mining and analytics methods.

The COVID-19 Pandemic, Rising Inflation, and Their Influence on Dining Out Frequency and Spending.

BACKGROUND: High intake of food away from home is associated with poor diet quality. This study examines how the COVID-19 pandemic period and Food Away from Home (FAFH) inflation rate fluctuations influenced dining out behaviors. METHODS: Approximately 2800 individuals in Texas reported household weekly dining out frequency and spending. Responses completed prior to the COVID-19 pandemic (2019 to early 2020) were compared to the post-COVID-19 period (2021 through mid-2022). Multivariate analysis with interaction terms was used to test study hypotheses. RESULTS AND CONCLUSION: From the COVID-19 period (before vs. after), the unadjusted frequency of dining out increased from 3.4 times per week to 3.5 times per week, while the amount spent on dining out increased from $63.90 to $82.20. Once the relationship between dining out (frequency and spending) was adjusted for FAFH interest rate and sociodemographic factors, an increase in dining out frequency post-COVID-19 remained significant. However, the unadjusted increase in dining out spending did not remain significant. Further research to understand the demand for dining out post-pandemic is warranted.

Food Oppression in a Pandemic.

COVID-related racial disparities represent a spectrum of injustices and inequalities. Focusing on food oppression, this essay argues that racism infuses food law and policy in ways that contribute to racially disparate COVID deaths and severe illnesses. USDA nutrition program participants were at a nutritional disadvantage when COVID hit. Yet, government responses focused on food insecurity, not nutritional quality. Racism against a predominantly Black and brown labor force of essential food workers - from fields to meat plants to grocery stores - created tolerance for the administration's failure to protect or compensate some of the country's most vulnerable workers. When COVID-driven supply issues threatened to narrow white people's activities and choices, the favored response was to keep their options open by sacrificing Black and brown workers. A food oppression lens - understanding how corporate interests drive food policy - is necessary to achieve food equality in this pandemic and beyond.

Association between diet history and symptoms of individuals having recovered from COVID-19.

BACKGROUND: Many studies show that people who eat a balanced diet have stronger immunity. The present work aimed to identify the effects of the diet history of COVID-19 patients having recovered from the disease on the occurrence and severity of symptoms. METHODS: The study sample consisted of 346 individuals aged 20-65 years. The participants' data and answers to an electronic questionnaire regarding their diet history and symptoms were collected. The study focused on four hard symptoms (fever, body pain, cough, and dyspnoea) to investigate the relationship between these symptoms and the consumption of specific immunity foods. RESULTS: Symptoms were reported by 88.1% of the participants eating none of the foods investigated, whereas 85.54% and 85.55% of the individuals with little or intensive food intake, respectively, experienced symptoms. CONCLUSIONS: Intake of specific functional foods might slightly reduce the occurrence of some symptoms.

Digital Forms of Commensality in the 21st Century: A Scoping Review.

The social act of eating together has been influenced and mediated by technologies in recent decades. This phenomenon has been investigated in different academic fields, but the topic is still in an incipient dimension, and there is a lack of consensus regarding terminology and definitions. The study aimed to characterize the main scientific findings regarding digital forms of commensality in the 21st century and to identify possible relationships between these practices and public health. A scoping review was conducted to identify papers published in different languages between 2001 and 2021. A total of 104 publications that combined commensality and technology in all contexts were included. Most studies were qualitative; from the Design and Technology field; used social media and video platforms or prototypes/augmented reality gadgets; and used different terms to refer to digital forms of commensality, allowing the analysis of the construction of field definitions over time. The intersections with health were observed from impacts on family/community engagement, culinary skills development, and mental health and eating habits. These practices also structured specific social interactions, such as virtual food communities and commensality, during the COVID-19 pandemic. This paper indicates the consistent growth of these practices and recommends the development of future research for theoretically and longitudinally deeper evaluations of the impacts of these new ways of eating together, especially regarding their effects on human health.

The Implementation of a Nutrition Intervention in Food Pantries: The Spirit of SWAP.

Background. Food insecurity, affecting approximately 10% of the U.S. population, with up to 40% or higher in some communities, is associated with higher rates of chronic conditions and inversely associated with diet quality. Nutrition interventions implemented at food pantries are an effective strategy to increase healthy food choices and improve health outcomes for people experiencing food and nutrition insecurity. Supporting Wellness at Pantries (SWAP), a stoplight nutrition ranking system, can facilitate healthy food procurement and distribution at pantries. Purpose. Guided by the RE-AIM Framework, this study assesses the implementation and outcomes of SWAP as nutritional guidance and institutional policy intervention, to increase procurement and distribution of healthy foods in pantries. Method. Mixed-methods evaluation included observations, process forms, and in-depth interviews. Food inventory assessments were conducted at baseline and 2-year follow-up. Results. Two large pantries in New Haven, Connecticut, collectively reaching more than 12,200 individuals yearly, implemented SWAP in 2019. Implementation was consistent prepandemic at both pantries. Due to COVID-mandated distribution changes, pantries adapted SWAP implementation during the pandemic while still maintaining the "spirit of SWAP." One pantry increased the percentage of Green foods offered. Challenges to healthy food distribution are considered. Discussion. This study has implications for policy, systems, and environmental changes. It shows the potential for SWAP adoption at pantries, which can serve as a guide for continued healthy food procurement and advocacy. Maintaining the "spirit of SWAP" shows promising results for food pantries looking to implement nutrition interventions when standard practice may not be possible.

Stemming the Shadow Pandemic: Integrating Sociolegal Services in Contact Tracing and Beyond.

The COVID-19 pandemic has shed light on the challenges of complying with public health guidance to isolate or quarantine without access to adequate income, housing, food, and other resources. When people cannot safely isolate or quarantine during an outbreak of infectious disease, a critical public health strategy fails. This article proposes integrating sociolegal needs screening and services into contact tracing as a way to mitigate public health harms and pandemic-related health inequities.

Modelling of salt intake reduction by incorporation of umami substances into Japanese foods: a cross-sectional study.

BACKGROUND: Evidence has demonstrated that excess sodium intake is associated with development of several non-communicable diseases. The main source of sodium is salt. Therefore, reducing salt intake in foods is an important global public health effort to achieve sodium reduction and improve health. This study aimed to model salt intake reduction with 'umami' substances among Japanese adults. The umami substances considered in this study include glutamate or monosodium glutamates (MSG), calcium diglutamate (CDG), inosinate, and guanylate. METHODS: A total of 21,805 participants aged 57.8 years on average from the National Health and Nutrition Survey was used in the analysis. First, we employed a multivariable linear regression approach with overall salt intake (g/day) as a dependent variable, adjusting for food items and other covariates to estimate the contribution of salt intake from each food item that was selected through an extensive literature review. Assuming the participants already consume low-sodium products, we considered three scenarios in which salt intake could be reduced with the additional umami substances up to 30%, 60% and 100%. We estimated the total amount of population-level salt reduction for each scenario by age and gender. Under the 100% scenario, the Japan's achievement rates against the national and global salt intake reduction goals were also calculated. RESULTS: Without compromising the taste, the 100% or universal incorporation of umami substances into food items reduced the salt intake of Japanese adults by 12.8-22.3% at the population-level average, which is equivalent to 1.27-2.22 g of salt reduction. The universal incorporation of umami substances into food items changed daily mean salt intake of the total population from 9.95 g to 7.73 g: 10.83 g to 8.40 g for men and 9.21 g to 7.17 g for women, respectively. This study suggested that approximately 60% of Japanese adults could achieve the national dietary goal of 8 g/day, while only 7.6% would meet the global recommendation of 5.0 g/day. CONCLUSIONS: Our study provides essential information on the potential salt reduction with umami substances. The universal incorporation of umami substances into food items would enable the Japanese to achieve the national dietary goal. However, the reduced salt intake level still falls short of the global dietary recommendation.

Determinants of Food Waste in Cluj-Napoca (Romania): A Community-Based System Dynamics Approach.

This study identifies the most relevant causes of food waste according to the perceptions of key stakeholders in Cluj-Napoca, Romania. Community-Based System Dynamics (CBSD), a qualitative approach, was used to reveal the determinants of food waste. CBSD was intended to encourage the system thinking of participants in the field of food waste. Consequently, CBSD helped us map and visualize the role of each identified cause in the system and the nature of their interactions. For the present study, four categories of stakeholders were involved: consumers, public administration, food waste business, and the NGO sector involved in food waste reduction. The result of each modeling session was a loop diagram of the main food waste determinants. A common perception reflected within each stakeholder group was that food waste could be minimized through upstream actions. The participants highlighted pro-environmental knowledge, awareness, and values as the prerequisites for fighting food waste. It was found that the lack of education and awareness of food waste directly impacted food waste generation. In addition, the role of education was underlined by participants as a contributor to changing individual and household practices, such as overbuying. The lack of connection between consumers and the food production process, coupled with consumerist practices and the rejection of 'ugly food', contributed to the decrease in the overall value people attributed to food. Governmental intervention, through legislation, was indicated by the CBSD participants as being key to increasing societal awareness and shaping the behavior of food chain actors. We concluded that food waste is a 'wicked problem' and the interlocking of the economic, social, political, and environmental spheres and the multitude of stakeholders' interests, values, and perceptions should be considered in designing sustainable solutions to combat food waste. Finally, this research testifies to the importance of engaging with diverse panels of stakeholders who, through the multitude of opinions and perspectives on the causes of food waste, can further create knowledge about the most appropriate ways to combat the food waste phenomenon.

Changes in Online Food Access During the COVID-19 Pandemic and Associations With Deprivation: Longitudinal Analysis.

BACKGROUND: Food prepared out of home is typically energy-dense and nutrient-poor. Online food delivery services have become a popular way to purchase such food. The number of accessible food outlets through these services can influence how frequently they are used. Anecdotally, food outlet access through online food delivery services increased in England between 2020 and 2022, in the context of the COVID-19 pandemic. However, the extent to which this access changed is poorly understood. OBJECTIVE: We aimed to investigate monthly changes in online access to food prepared out of home in England in the context of the first 2 years of the COVID-19 pandemic compared with November 2019 and the extent to which any changes were associated with deprivation. METHODS: In November 2019 and monthly between June 2020 and March 2022, we used automated data collection to construct a data set containing information about all food outlets in England registered to accept orders through the leading online food delivery service. Across postcode districts, we identified the number and percentage of food outlets registered to accept orders and the number that was accessible. We used generalized estimating equations (adjusted for population density, the number of food outlets in the physical food environment, and rural/urban classification) to investigate the change in outcomes compared with prepandemic levels (November 2019). We stratified analyses by deprivation quintile (Q). RESULTS: Across England, the summed number of food outlets registered to accept orders online increased from 29,232 in November 2019 to 49,752 in March 2022. Across postcode districts, the median percentage of food outlets registered to accept orders online increased from 14.3 (IQR 3.8-26.0) in November 2019 to 24.0 (IQR 6.2-43.5) in March 2022. The median number of food outlets accessible online decreased from 63.5 (IQR 16.0-156.0) in November 2019 to 57.0 (IQR 11.0-163.0) in March 2022. However, we observed variation by deprivation. In March 2022, the median number of outlets accessible online was 175.0 (IQR 104.0-292.0) in the most deprived areas (Q5) compared with 27.0 (IQR 8.5-60.5) in the least deprived (Q1). In adjusted analyses, we estimated that the number of outlets accessible online in the most deprived areas was 10% higher in March 2022 compared with November 2019 (incidence rate ratios: 1.10, 95% CI 1.07-1.13). In the least deprived areas, we estimated a 19% decrease (incidence rate ratios: 0.81, 95% CI 0.79-0.83). CONCLUSIONS: The number of food outlets accessible online increased only in the most deprived areas in England. Future research might attempt to understand the extent to which changes in online food access were associated with changes in online food delivery service use and the possible implications on diet quality and health.

Environmental and public health co-benefits of consumer switches to immunity-supporting food.

During COVID-19, there has been a surge in public interest for information on immunity-boosting foods. There is little scientific support for immunity-supporting properties of specific foods, but strong evidence for food choice impacts on other health outcomes (e.g. risk of non-communicable disease) and environmental sustainability. Here, we relate online recommendations for "immunity-boosting" foods across five continents to their environmental and human health impacts. More frequently recommended food items and groups are plant based and have lower land use and greenhouse gas emission impacts plus more positive health outcomes (reducing relative risks of mortality or chronic diet-related diseases) per serving of food. We identify trade-offs between environmental outcomes of increasing consumption of recommended food items, with aquatic environment impacts increasing with food recommendation frequency. People's reliance on the Internet for health information creates an opportunity to consolidate behaviour change towards consuming foods with multiple co-benefits. Our study identifies win-win options for nudging online information-seeking behaviour towards more sustainable choices for terrestrial biodiversity conservation and human health.

Food for thought: Examining the relationship between low calorie density foods in Instagram feeds and disordered eating symptoms among undergraduate women.

BACKGROUND: Ample studies have tested how viewing bodies on social media impacts eating disorder symptoms; however, the relationship between viewing food images on social media and disordered eating remains understudied. This study investigated whether viewing images of healthy, palatable food on Instagram impacted disordered eating attitudes across two samples of undergraduate women. METHODS: This pre-registered online study was conducted at two sites. Participants identifying as female (study 1 n = 222; study 2 n = 214) were randomly assigned to view one of two Instagram feeds - either a feed featuring low calorie, aesthetically pleasing foods or a control condition featuring travel images. Participants completed state measures of disordered eating intentions, self-esteem, and body image before and after viewing the feeds. RESULTS: A main effect of condition on disordered eating intentions was found at the Midwestern site, but not the Southeastern site. CONCLUSIONS: Viewing healthy palatable food images on Instagram could increase risk for disordered eating behaviors among college females. If findings are replicated, individuals vulnerable to disordered eating may benefit from removing these types of feeds from their social media. Further research is needed to determine whether other forms of visual content on Instagram may be associated with disordered eating.
