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.

Many American college students fail to meet dietary guideline recommendations for fruits, vegetables, and fiber. Pulses are a subgroup of legumes, harvested solely for dry grain seeds within a pod. Commonly consumed pulses include dry beans, dry peas, lentils, and chickpeas. Pulses are high in shortfall nutrients and could fill some nutritional gaps of college students. However, little is known about pulse intakes among young adults. The study aims were: (1) to identify knowledge, attitudes, and practices regarding pulse consumption; and (2) to describe experiences of preparing dry pulses among college students. A convenience sample of 1433 students aged 18–30 enrolled at a Midwestern university in the United States completed an online survey in April 2020. Demographic and attitude variables were compared by the monthly count of pulse types eaten using chi-square, analysis of variance, and logistic regression modeling to predict pulse type intakes. Higher numbers of pulse types eaten was associated with being White, vegetarian/vegan, higher cooking self-efficacy, positive attitudes toward pulses, and greater daily intake of fruits, vegetables, and fiber. Knowledge and experience of cooking dry pulses was low, with canned pulses purchased more often. College students may not be consuming pulses due to unfamiliarity with them, low knowledge of nutrition benefits, and a general lack of cooking self-efficacy. Increased familiarization and promotion surrounding pulses may increase their consumption.

Despite decades of messaging, most Americans still consume excess fats and sugars, but inadequate fiber, potassium, and calcium. Nutrient-rich foods (NRFs) have a high density of favorable nutrients related to calories. Choosing NRFs could lower risk of nutrition-related chronic diseases and aid in their control. We hypothesized that having greater knowledge of NRFs, the presence of a nutrition-related chronic disease or risk factor, and positive Health Belief Model (HBM) views would be predictive of the likelihood of eating NRFs. Through a national online survey panel, 976 adults aged 18–80 completed demographic, health, NRF knowledge, attitudes, and HBM construct questions. Participants were 77% White, 52% women, and 55% had a nutrition-related disease or risk factor. Multivariable HBM scales were generated by theory, principal components, and reliability analysis. NRF knowledge was significantly higher for women, Whites, households without children, and persons without a nutrition-related disease (all p ≤ 0.015). ‘Likelihood of eating NRFs’ was significantly higher for persons with a nutrition-related disease, Whites, married participants, main food shoppers, and households with children (all p ≤ 0.022). Regressing demographic and HBM constructs on the ‘likelihood of eating NRFs’ resulted in R2 of 0.435. Nutrition-related disease and HBM constructs of self-efficacy, perceived benefits, and cues to action were predictive of the likelihood of eating NRFs, but higher NRF knowledge was negatively associated.

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.

With high levels of protein, fiber, folate, iron and other micronutrients, the Dietary Guidelines for Americans recommends eating beans for optimal nutrition. Low-income women are at greater risk of nutrition-related health disparities. Use of beans may change among Hispanic women (Latinas) during acculturation, but few studies exist that describe specific preferences of this important traditional food. Preserving or promoting beans in the diets of all low-income women could improve dietary quality. The study objectives were to describe consumption frequency, purchasing patterns, and attitudes toward dry and canned beans, by acculturation level among Latinas and by ethnicity with non-Hispanic White women. Survey data were collected from 356 women (µ 32 y ± 9 y; 81% Latina), who were enrolled in, or eligible for, a federal nutrition assistance, or unemployment, program in Phoenix, Arizona, USA. Participants had positive attitudes toward beans overall. Less acculturated and bicultural Latinas bought dry beans more often than their peers. Price was considered important in canned bean selection for Non-Hispanic White women, and less acculturated Latinas had poorer attitudes toward canned. Awareness of these attitudes and preferred traits of low-income women suggests ways to message populations to maintain or increase bean consumption. Negative views of canned beans by Latinas should be investigated further. Inclusion of canned beans in nutrition assistance programs may benefit those unfamiliar with preparing dry beans.

Bean consumption is known to lower blood cholesterol and postprandial blood glucose. With higher chronic disease risk, low-income men could theoretically benefit from increased bean intakes. The study objective was to explore low-income men’s food behaviors, bean health benefit awareness, and bean consumption practices and preferences. Seventy-one low-income men aged 18–65 years (µ 41 ± 12.7; 53% white, 16% black, 31% Hispanic) completed a survey on health risks, food behaviors, bean health knowledge, attitudes toward dry and canned beans, and bean preferences. Eighty-seven percent had one or more health risk factors of physical inactivity, smoking, or obesity. Most men compared food prices, and thought about healthy food choices for their families, but few planned meals or read nutrition facts labels. White men had significantly higher bean health benefit knowledge than black or Hispanic men (p < 0.01). Most men liked the taste of beans, disagreed dry beans took too long to prepare, and 79% ate them at least 2–3 times per month. Forty-nine percent agreed beans caused intestinal gas. Improving men’s awareness of the health benefits of beans as well as leveraging existing positive attitudes may be useful approaches to increase bean consumption among low-income and minority male populations.
