Evaluating Food Procurement against the EAT-Lancet Planetary Health Diet in a Sample of U.S. Universities.

Aligning institutional food procurement with planetary health targets offers opportunities to improve nutrition and reduce food-related greenhouse gas (GHG) emissions. This study compared foods procured by 19 university dining programs in the U.S. in 2022 with the EAT-Lancet planetary health diet. Each university's procurement was then modeled to align with the EAT-Lancet planetary health diet, and changes to Healthy Eating Index (HEI) scores and GHG emissions were evaluated. For a subset of universities that provided cost data, changes in annual total food costs were also estimated. Universities in this study exceeded EAT-Lancet planetary health targets for beef (x- = 657% of target), pork (x- = 587%), poultry (x- = 379%), and eggs (x- = 293%). All universities failed to achieve planetary health targets for legumes and nuts (x- = 39% of the target) and vegetables (x- = 68%). Aligning food procurement with the planetary health diet would result in an estimated average 46.1% reduction in GHG emissions and a 19.7 point increase in HEI scores. Universities that provided cost data saw an average 9.7% reduction in food costs in the EAT-Lancet-aligned scenario. The procurement metrics assessed in this study can help university dining programs and other institutional food service organizations set goals and monitor progress toward planetary health targets.

Food Insecurity and Delayed or Forgone Medical Care During the COVID-19 Pandemic.

Objectives. To describe food insecurity in the United States in December 2020 and examine associations with underuse of medical care during the COVID-19 pandemic. Methods. We fielded a nationally representative Web-based survey in December 2020 (n = 8318). Multivariable logistic regression models and predicted probabilities were used to evaluate factors associated with food insecurity and compare the likelihood of delaying or forgoing medical care because of cost concerns by food security status. Results. In December 2020, 18.8% of US adults surveyed reported experiencing food insecurity. Elevated odds of food insecurity were observed among non-Hispanic Black, Hispanic, and low-income respondents. Experiencing food insecurity was significantly associated with a greater likelihood of forgoing any type of medical care as a result of cost concerns. Conclusions. Food insecurity during the COVID-19 pandemic disproportionately affected non-White and low-income individuals. Experiencing food insecurity was a significant risk factor for delaying or forgoing medical care, an association that could have cumulative short- and long-term health effects. Public Health Implications. Comprehensive policies that target the most at-risk groups are needed to address the high rates of food insecurity in the United States and mitigate its adverse health effects.

Why don't college freshmen meet the US dietary guidelines for added sugar, refined grains, sodium, and saturated fat?

OBJECTIVE: The objective of the study was to evaluate how well college students meet U.S. dietary guidelines by examining the mean intakes of nutrients to limit (sodium, sugar, refined grains, and saturated fat), and what factors lead to exceeding the dietary recommendations. PARTICIPANTS: Participants were first-year undergraduate students (N = 269). METHODS: Diet was assessed using a DHQ-III and estimated with food source composition tables. Multivariable logistic regression analysis was used to model variables associated with exceeding the recommendations. One-sample t-tests were performed to compare the cohort with national intakes. RESULTS: One-third met added sugar guidelines; only 4% met daily refined grains requirements, Fewer than half met saturated fat guidelines, and slightly over half met recommended sodium guidelines. Level of physical activity, race/ethnicity, and living on campus were the important predictors for exceeding recommended intakes. CONCLUSIONS: Most students do not adhere to the U.S. dietary guidelines for nutrients to limit.

Attitudes and beliefs about how chefs can promote nutrition and sustainable food systems among students at a US culinary school.

OBJECTIVE: Chefs have the potential to influence diet quality and food systems sustainability through their work. We aimed to assess the attitudes and perceptions of culinary students about nutrition and sustainability as part of their roles, responsibilities and future work as chefs. DESIGN: We surveyed students attending the Culinary Institute of America (CIA) in the fall of 2019 (n 546). Descriptive statistics compared food priority rankings and Likert-scale distributions of nutrition and sustainability attitudes and beliefs. Adjusted generalised linear models were used to evaluate whether there were differences in attitudes and beliefs across demographic groups. SETTING: The CIA, a private, not-for-profit college and culinary school with US campuses in New York, California and Texas. PARTICIPANTS: Students >18 years old currently enrolled in any of the school's associate's or bachelor's degree programs. RESULTS: Students agreed that chefs should be knowledgeable about nutrition (96·0 %) and the environmental impact of their ingredients (90·8 %) but fewer considered healthfulness (57·8 %) and environmental impact (60·2 %) of their food to be primary considerations in their career as a chef. Taste was the primary factor influencing culinary students' food choices but food priorities differed by race/ethnicity. CONCLUSIONS: Culinary students believe nutrition and sustainability are important. Opportunities exist to empower them with knowledge and skills for promoting public health and sustainable food systems in their future work as chefs.

Dietary Intake and Representativeness of a Diverse College-Attending Population Compared with an Age-Matched US Population.

Young adults typically gain more dietary autonomy as they start college, though this can also present nutritional challenges; however, research on the generalizability of their dietary intake data is scarce. To address this representativeness concern, we compared food and nutrient intakes reported by college freshmen attending a large, diverse university to an age-matched sample from the National Health and Nutrition Examination Survey (NHANES). We studied 269 students 18-24 years old recruited through the Mason: Health Start Here (HSH) study, a population-based cohort study of college students. Diet was assessed using a diet history questionnaire (DHQ-III) and estimated with food source composition tables. The NHANES sample of 835 adults was the reference dataset. Reported dietary intakes were weighted and compared with national intakes via t-tests. We observed comparable energy, carbohydrate, fat, and protein intakes in both groups; however, the HSH cohort reported a higher density intake of most micronutrients than the NHANES sample. Differences between these samples in intake, mode of dietary assessment administration, and reactivity may help explain the differences detected. These results demonstrate that when appropriately contextualized in terms of methodology and potential sources of bias, single college studies can be useful for understanding nutrition in young adults more broadly.

Increasing Vegetable Intake by Emphasizing Tasty and Enjoyable Attributes: A Randomized Controlled Multisite Intervention for Taste-Focused Labeling.

Healthy food labels tout health benefits, yet most people prioritize tastiness in the moment of food choice. In a preregistered intervention, we tested whether taste-focused labels compared with health-focused labels increased vegetable intake at five university dining halls throughout the United States. Across 137,842 diner decisions, 185 days, and 24 vegetable types, taste-focused labels increased vegetable selection by 29% compared with health-focused labels and by 14% compared with basic labels. Vegetable consumption also increased. Supplementary studies further probed the mediators, moderators, and boundaries of these effects. Increased expectations of a positive taste experience mediated the effect of taste-focused labels on vegetable selection. Moderation tests revealed greater effects in settings that served tastier vegetable recipes. Taste-focused labels outperformed labels that merely contained positive words, fancy words, or lists of ingredients. Together, these studies show that emphasizing tasty and enjoyable attributes increases vegetable intake in real-world settings in which vegetables compete with less healthy options.
