Black Bean Pasta Meals with Varying Protein Concentrations Reduce Postprandial Glycemia and Insulinemia Similarly Compared to White Bread Control in Adults.

Postprandial glycemic and insulinemic effects of three black bean pastas were evaluated among eighteen normoglycemic adults (8 men, 10 women) in a randomized crossover trial. Black beans were milled into flour using a commercial Knife or compression/decompression mill (C/D mill). The C/D-mill-derived pastas had medium protein (Combo-MP) and low protein (Cyclone-LP) concentrations. Three black bean flour pastas (Knife, Combo-MP, and Cyclone-LP) were compared to two controls: white bread and whole black beans. Treatments contained 50 g of available carbohydrate. Plasma glucose, serum insulin, and appetite measures were collected at fasting and 30, 60, 90, 150, and 180 min postprandial. Gastrointestinal symptoms were evaluated 10-12 h postprandial. ANOVA (one-way, repeated measures) was used to evaluate satiety, gastrointestinal symptoms, sensory variables, glucose and insulin differences from baseline, and incremental area under the curve (iAUC) by time and/or treatment. Three-hour glucose and insulin iAUCs were lower with whole black beans than white bread. Black bean pasta meals increased satiety, reduced appetite, and produced numerically lower glucose and insulin responses than white bread. However, no differences were observed between pasta types, indicating a similar metabolic response regardless of milling technique. Our results provide evidence for dietary guidance to reduce postprandial glucose and related health risks through pulse food products.

Predictors of Plant-Based Alternatives to Meat Consumption in Midwest University Students.

OBJECTIVE: To assess the prevalence of plant-based alternatives to meat consumption in students at a Midwest university, describe associations between demographics, environmental concern attitudes, and consumption, and determine variables statistically associated with trying the plant-based alternatives. DESIGN: Descriptive cross-sectional convenience sample; self-administered online surveys. SETTING: College students at a Midwest university. PARTICIPANTS: Currently enrolled students aged 18-30 taking courses on campus as of March 2020. MAIN OUTCOME MEASURES: Plant-based alternative consumption; demographics; vegetarian status; environmental attitudes; influences on food choices; and trusted sources of food information. ANALYSIS: Bivariate comparisons for consumption of plant-based alternatives; logistic regression analysis. RESULTS: Fifty-five percent had tried a plant-based meat alternative. Top reasons were enjoying new foods and curiosity about the products. Out-of-state residency, vegetarian status, and 10 of 11 environmental attitude statements were significantly associated with plant-based alternative consumption (P < 0.05). About 30% of consumers indicated they wanted to eat less meat and that plant alternatives were better for the environment. Nonconsumers had less favorable views of meatless meals. CONCLUSIONS AND IMPLICATIONS: This study supports that positive environmental attitudes were predictive of plant-based alternative consumption among college students. Increased awareness and familiarity could encourage consumption among this population.

Food Security Characteristics Vary for Undergraduate and Graduate Students at a Midwest University.

The study objective was to determine prevalence of food insecurity and its associations with socioecological model (SEM) characteristics for undergraduate and graduate students. An online questionnaire was distributed to a convenience sample of students aged 18-34 at a Midwestern university. Of the 938 responses, 675 were complete for analysis. Outcome measures included demographics, food security level, housing, food access barriers, coping strategies, and food assistance program usage. Results found that predictors associated with undergraduate food insecurity included non-White race, receipt of financial aid, lower self-reported health status, living off-campus, employment, and food cost (p < 0.001). Graduate student food insecurity was associated with Asian self-identification, employment, food cost, no time to prepare foods, and lack of foods for dietary needs (p < 0.001). Students with food insecurity were more likely to buy cheap food (p < 0.001). Almost 50% of food-insecure undergraduates asked friends or family to help buy food. Food-insecure students were more likely to want information on meal preparation and budgeting. More graduate students were likely to know of and use food pantries. Overall, food insecurity was higher among undergraduate than graduate students. Universities should consider institutional and policy changes tailored to the separate populations to mitigate the prevalence of campus food insecurity.

Effects of COVID-19 on University Student Food Security.

During COVID-19 restrictions in spring 2020, college students experienced closed dormitories and increased unemployment and many students moved in with their families. College students were vulnerable to food insecurity pre-pandemic and this study examined how the living situations and food security status changed for Midwestern university students due to COVID-19 restrictions. An email survey administered to Iowa State University students between the ages of 18 and 30 who physically attended campus prior to its closure produced 1434 responses. Students living with a parent or guardian increased by 44% and were less likely to experience food insecurity or less likely to work. They had lower stress and ate more home-cooked meals. Students living on their own had higher rates of food insecurity, greater stress, poorer health status, higher cooking self-efficacy, and worked more hours. Seventeen percent of all students were food insecure; related factors were non-White ethnicity, lower cooking self-efficacy, undergraduate status, receipt of financial aid, employment, stress, living in the same situation as before the campus closure, and consumption of more take-out or fast food. These individuals had more barriers to food access. Knowledge of these factors provide useful information to inform future support services for this population in similar conditions.

Putting Knowledge into Practice: Low-Income Women Talk about Food Choice Decisions.

Insights into barriers and facilitators for healthy eating are needed to improve low-income women's diets and to decrease disease risk. The study objectives were to explore women's qualitative perceptions of influences on their food choices such as food security, their knowledge of nutrition-related health risk factors and self-efficacy for diet change, and their dietary intakes in practice. Thirty-six women, aged 19-50, who were eligible to receive income-based assistance were recruited in central Iowa. Focus group discussions on defining healthy foods, influences on food choice, and nutrition information sources were analyzed using a socioecological model framework. Demographics, nutrient intake estimates, food security status, health behaviors, and self-efficacy for nutrition behavior change were collected by survey. Most participants were White (61%), single (69%), food insecure (69%), and living with children (67%). Few women met dietary recommendations. Barriers to healthy eating include cost, convenience/preparation time, family taste preferences, and limitations of federal food assistance programs. Facilitators are high self-efficacy for nutrition change and health knowledge on average. These results challenge the strategy of using nutrition education to improve healthy eating and instead show that intervention messaging should focus on limited, achievable steps to improve dietary choices that fit within cost, convenience, and taste constraints.

African-American Views of Food Choices and Use of Traditional Foods.

Objectives: In this study, we describe dietary intakes and examine variation among African-American adults in the Southwest, and identify barriers to engaging in healthy dietary behaviors, and use of traditional African-American foods, including pulses. Methods: Using mixed-methods parallel analysis, 97 African Americans aged 25-60 years completed surveys on lifestyle and dietary habits prior to focus group discussions in 3 geographic regions of Arizona. We identified themes in the qualitative transcripts using an inductive approach informed by Grounded Theory. Survey data were compared by sex, and age cohort via chi-square and ANOVA. Results: Qualitative knowledge of healthy choices was high for most participants, but survey dietary in-takes were below recommendations for fruit, vegetables, fiber, and pulses. Greens, fried chicken and fish, barbequed meats, okra-corn-tomato mix, grits, and sweet potatoes were eaten at least twice a month by 30%-50%. Statistically significant food consumption differences were observed by sex, age, and income. Healthy eating barriers included cost, access, convenience or time to prepare, accessibility, and cultural preferences and traditions. Interest in food preparation education was a common theme. Conclusions: Arizona African Americans retain elements of traditional foods in their diet. Health education should offer practical solutions for the cited barriers, be culturally relevant, and build on existing knowledge.
