BACKGROUND: Red meat production is a leading contributor to food-related greenhouse gas emissions. Decreasing red meat intake can mitigate climate change and lower risk of diet-related diseases. OBJECTIVE: The goal of this study is to evaluate university students perceptions of climate-friendly behaviors and to assess how these perceptions are associated with the frequency of red meat intake. DESIGN: Cross-sectional survey SETTING: A large, public California university and a large, public Michigan university PARTICIPANTS: Undergraduate students from a California university (n = 721) and a Michigan university (n = 568) MAIN OUTCOME MEASURES: Perceptions of climate-friendly behaviors and frequency of red meat intake STATISTICAL ANALYSIS: Differences in perceptions by student characteristics were compared using t-tests and one-way analysis of variance. Associations between perceptions of climate-friendly behaviors and red meat intake frequency were examined using generalized linear models, adjusted for sociodemographic covariates. RESULTS: Across both universities, students rated reducing meat intake as less effective than other climate change mitigation behaviors such as recycling and using less plastic. However, students who reported (1) making food and beverage choices that are good for the environment, (2) making food and beverage choices that reduce climate change impact, or (3) agreeing that eating less meat is an effective way to combat climate change reported 10% to 25% lower frequency of red meat intake for each point higher on the agreement scale. In contrast, making food and beverage choices motivated by health was not associated with frequency of red meat intake. CONCLUSIONS: Sustainability motivations and perceptions of meats climate impact were associated with lower frequency of red meat intake, despite the overall moderate rating of eating less meat as an effective climate change mitigator. This research lends support to behavioral interventions, public education campaigns, and policies aiming to reinforce sustainable dietary patterns in young adults.

The COVID-19 pandemic caused widespread non-essential business closures in the U.S., which may have disproportionately impacted food consumption in lower-income communities, in part due to reduced access to healthy and affordable foods, as well as occupations that may have required working outside the home. The aims of this study were to examine restaurant dining behaviors (including drive-through, takeout, and delivery) at fast-food and non-fast-food (i.e., fast casual and full-service ['other']) restaurants and the impact on diet quality among racially/ethnically diverse low-income adults during the early months of the pandemic. Participants completed an online survey using CloudResearch regarding restaurant dining behaviors in the past week (during June 2020) and during a typical week prior to the pandemic. Diet quality was measured using the Prime Diet Quality Score (PDQS). Surveys from 1,756 low-income adults (incomes

PURPOSE Adults with a triple multimorbidity (hypertension, prediabetes or type 2 diabetes, and overweight or obesity), are at increased risk of serious health complications, but experts disagree on which dietary patterns and support strategies should be recommended. METHODS We randomized 94 adults from southeast Michigan with this triple multimorbidity using a 2 * 2 diet-by-support factorial design, comparing a very low-carbohydrate (VLC) diet vs a Dietary Approaches to Stop Hypertension (DASH) diet, as well as comparing results with and without multicomponent extra support (mindful eating, positive emotion regulation, social support, and cooking). RESULTS Using intention-to-treat analyses, compared with the DASH diet, the VLC diet led to greater improvement in estimated mean systolic blood pressure (-9.77 mm Hg vs -5.18 mm Hg; P = .046), greater improvement in glycated hemoglobin (-0.35% vs -0.14%; P = .034), and greater improvement in weight (-19.14 lb vs -10.34 lb; P = .0003). The addition of extra support did not have a statistically significant effect on outcomes. CONCLUSIONS For adults with hypertension, prediabetes or type 2 diabetes, and overweight or obesity, the VLC diet resulted in greater improvements in systolic blood pressure, glycemic control, and weight over a 4-month period compared with the DASH diet. These findings suggest that larger trials with longer follow-up are warranted to determine whether the VLC diet might be more beneficial for disease management than the DASH diet for these high-risk adults.

BackgroundHealth-related warning labels may reduce the intake of sugar-sweetened beverages (SSBs), but the effectiveness of such labels in real-world settings is not well established.ObjectivesWe investigated the influence of warning labels on SSB intake among college students at a large public Midwestern university.MethodsWe conducted a quasi-experimental intervention study among 840 undergraduate students recruited from 3 dining halls on 1 university campus. One dining hall was selected as the intervention (I) site, whereas the other dining halls served as control (C) sites. In January 2019, warning labels were posted on SSB dispensers at the I site. All students reported their beverage intake using a modified beverage frequency questionnaire 2 mo before and 2 mo after the warning label implementation. Generalized linear models examined the influence of the warning labels on SSB consumption at the I site compared with the C sites, adjusting for students' sociodemographic characteristics.ResultsIn the sample, 68% were aged 17-18 y old at baseline, and 51% identified as female. From baseline to follow-up, there was a 19% decrease in SSB intake at the I site, compared with a 5% decrease at the C sites (P = 0.049 comparing I with C). This difference was driven by significant decreases in the intakes of fruit-flavored drinks, sweetened teas, and flavored milk at the I site compared with the C sites. Although not an SSB, 100% fruit juce consumption decreased 21% at the I site, compared with a 1% increase at the C sites (P = 0.01 comparing I with C). No significant differences were observed in the intakes of soda, energy drinks, sweetened coffees, and nonsugary drinks at the I site compared with the C sites.ConclusionsWarning labels were effective in reducing SSB intake among college students, particularly for fruit-flavored drinks, sweetened teas, and flavored milk.This trial was registered at clinicaltrials.gov as NCT04435145.

Objectives Growing research suggests that food insecurity is associated with worse cognitive functioning; however, prospective studies are needed to examine food insecurity and dementia risk. Using longitudinal and nationally representative data, we examined the effects of food insecurity on dementia risk among older adults. Methods Data were from 3,232 adults (≥65 years) from the Panel Study of Income Dynamics. Food insecurity was assessed biennially using the U.S. Household Food Security Survey Module from 2015 to 2019. Probable dementia risk was assessed biennially using the Eight-Item Interview to Differentiate Aging and Dementia from 2017 to 2021. Inverse probability weighting and marginal structural models were used to account for the time-varying nature of food insecurity and sociodemographic and health confounders. Results After accounting for baseline and time-varying sociodemographic and health covariates, there was a 2-fold higher association between food insecurity and probable dementia risk (odds ratio 2.11, 95% confidence interval: 1.12–3.98). The results were robust to expanding the exposure to include marginal food security and the outcome to include informant-reported memory loss. Furthermore, there was no evidence of heterogeneity in the association of food insecurity and probable dementia risk by sex, race, and ethnicity, or participation in the Supplemental Nutrition Assistance program. Discussion Food insecurity is a modifiable social determinant of health. Interventions and policies are needed to reduce food insecurity and promote healthy aging for older adults.

Front-of-package labels indicating a product's environmental footprint (i.e., eco-score labels) offer promise to shift consumers towards more sustainable food choices. This study aimed to understand whether eco-score labels impacted consumers' perceptions of environmental sustainability and intentions to purchase sustainable and unsustainable foods. US parents (n = 1,013) completed an online experiment in which they were shown 8 food products (4 sustainable and 4 unsustainable). Participants were randomized to a control (n = 503, barcode on product packaging) or eco-score label group (n = 510, eco-score label on product packaging). The eco-score label was color-coded with a grade of A-F based on the product's environmental footprint, where "A" indicates relative sustainability and "F" indicates relative unsustainability. Participants rated each product's environmental sustainability and their future likelihood of purchase. We used multilevel mixed-effects linear regression models and examined moderation by product category and sociodemographic characteristics. The eco-score label lowered perceived sustainability of unsustainable products by 13% in relative terms or -0.4 in absolute terms (95% CI -0.5, -0.3; p<0.001). The eco-score label increased perceived sustainability of sustainable products by 16% in relative terms or 0.6 in absolute terms (95% CI 0.5, 0.7, p<0.001). Effects on purchase intentions were smaller, with a 6% decrease for unsustainable products (p = 0.001) and an 8% increase for sustainable products (p<0.001). For unsustainable products, the effect of eco-score labels on sustainability perceptions was greater for older adults, men, participants with higher educational attainment, and participants with higher incomes. For sustainable products, the effect of ecolabels on sustainability perceptions was greater for those with higher educational attainment. Eco-score labels have the potential to direct consumers towards more sustainable products. Future studies should investigate eco-score label effectiveness on behavioral outcomes.

The COVID-19 pandemic pushed millions of Americans into food insecurity. Food policy councils (FPCs) across the country played a vital role in organizing coordinated food responses across multiple sectors. We used a social network analysis (SNA) approach to investigate: (1) the network of partnering organizations and agencies within FPCs; (2) how the characteristics of FPCs' network partnerships (i.e., degree, coreness, and density) related to programmatic, policy, and advocacy actions in response to the pandemic; and (3) how FPCs' use of a racial or social equity framework shifted their network partnerships and responses. Local government agencies and food supply chain actors were core in FPCs' network partnerships, while public utilities, correctional facilities, social justice groups, and others were non-core partners. Network density was more likely to be associated with any action by FPCs, and it was especially pronounced for advocacy actions taken by FPCs; trends were similar among FPCs that reported using a racial or social equity framework. The findings begin to uncover core actors in FPCs' partnerships and opportunities to establish new partnerships, particularly with social justice groups. The results also suggest that network density (interconnectedness) may be more important than other network characteristics when responding to food-related needs. [ABSTRACT FROM AUTHOR]
