First-year college students are at particular risk of dietary maladaptation during their transition to adulthood. A college environment that facilitates consistent access to nutritious food is critical to ensuring dietary adequacy among students. The objective of the study was to examine perceptions of the campus food environment and its influence on the eating choices of first-year students attending a minority-serving university located in a food desert. Focus group interviews with twenty-one first-year students were conducted from November 2016 to January 2017. Students participated in 1 of 5 focus groups. Most interviewees identified as being of Hispanic/Latino or Asian/Pacific Islander origin. A grounded theory approach was applied for inductive identification of relevant concepts and deductive interpretation of patterns and relationships among themes. Themes related to the perceived food environment included adequacy (i.e., variety and quality), acceptability (i.e., familiarity and preferences), affordability, and accessibility (i.e., convenience and accommodation). Subjective norms and processes of decisional balance and agency were themes characterizing interpersonal and personal factors affecting students’ eating choices. The perceived environment appeared to closely interact with subjective norms to inform internal processes of decision-making and agency around the eating choices of first-year students attending a minority-serving university campus located in a food desert.

The transition to nutritional independence makes new college students vulnerable to alterations in eating patterns, which can increase the risk of cardiometabolic disorders. The aim of the study was to examine the potential benefits of almond vs. cracker snacking in improving glucoregulatory and cardiometabolic profiles in new college students. A randomized controlled, parallel-arm, 8-week intervention of 73 college students (BMI: 18–41 kg/m2) with no cardiometabolic disorders was conducted. Participants were randomized into either an almond snack group (56.7 g/day; 364 kcal; n = 38) or Graham cracker control group (77.5 g/day; 338 kcal/d; n = 35). Chronic, static changes were assessed from fasting serum/plasma samples at baseline, and after 4 and 8 weeks. Acute, dynamic effects were assessed during a 2-h oral glucose tolerance test (OGTT) at 8 weeks. Almond snacking resulted in a smaller decline in HDL cholesterol over 8 weeks (13.5% vs. 24.5%, p < 0.05), 13% lower 2-h glucose area under the curve (AUC), 34% lower insulin resistance index (IRI) and 82% higher Matsuda index (p < 0.05) during the OGTT, despite similar body mass gains over 8 weeks compared with the cracker group. In general, both almond and cracker snacking reduced fasting glucose, and LDL cholesterol. Conclusions: Incorporating a morning snack in the dietary regimen of predominantly breakfast-skipping, first-year college students had some beneficial effects on glucoregulatory and cardiometabolic health. Almond consumption has the potential to benefit postprandial glucoregulation in this cohort. These responses may be influenced by cardiometabolic risk factor status.

Background: Lack of access to adequate, safe, and nutritious food is a major concern for the Afghan population due to ongoing war and humanitarian crises. Recently resettled Afghan refugees in the US continue to face challenges securing adequate, nutritious food resources in new environments. This study examined Afghan refugees’ food access and insecurity in the San Joaquin Valley, California. Methods: Semi-structured, in-depth interviews were conducted to collect the perspectives and experiences of key informants and newly arrived Afghan refugees. Results: This study highlights environmental and structural factors (availability and accessibility of grocery stores; availability of religious-appropriate items in the stores; the public benefit received by a family; and public transportation) and individual factors (religious and cultural practices; financial and language barriers) as major determinants of post-resettlement food insecurity. Conclusion: Increasing the accessibility and affordability of culturally and religiously appropriate food items within the US food system, enhancing the collaboration of community volunteers and resettlement organizations in the direct assistance of new families, and providing continuous access to public benefits are possible steps to mitigate the risk of food insecurity among Afghan refugees. This study suggests a continuous examination of the degree of food insecurity in this population and its attendant health impacts.

Food insecurity disproportionately affects low-income, racially marginalized, and rural communities. The COVID-19 pandemic led to higher demand for emergency food distribution, potentially impacting food pantry operations and services. Limited research exists assessing consumer nutrition environments of pantries in rural regions. To assess the consumer nutrition environment of rural food pantries and report challenges and adaptations encountered during the pandemic. A mixed-methods, cross-sectional survey. Nineteen food pantry representatives from California's San Joaquin Valley were surveyed between August 2020 and June 2021. Representatives were eligible if their pantry served the general population and was open at least once a week. Nine were church-based pantries, and 10 were from other settings. The Nutrition Environment Food Pantry Assessment Tool (NEFPAT) measured the nutrition food environment and scored pantries as bronze (0-15), silver (16-31), or gold (32-47) categories. Eleven items were developed to explore pandemic-related challenges. Independent χ2 tests assessed the relationship between the organization type and NEFPAT scores and food supply sources. Fisher's exact test explored associations between food pantry type, NEFPAT category, and challenges. Nonparametric tests were run on non-normally distributed data. Inductive content analysis was used to examine open-ended pandemic-related questions. The nutrition environment of most pantries was suboptimal, because no pantry scored in the "gold" category based on total NEFPAT scores (median, 18 of 47). No statistically significant differences were found in the NEFPAT scores by organization type. Most pantries did not provide healthy food nudges or culturally diverse foods. Key COVID-19 challenges encountered consisted of supply- and demand-side issues, including reduced personnel, capacity, and resources, and increased client quantity and demand for food. Assessing the nutrition environment of rural food pantries revealed gaps and strategies for improvement, including the use of healthy nudges and increasing the availability of culturally diverse foods.
