Food Resource Management and Healthy Eating Focus Associates with Diet Quality and Health Behaviors in Low-Income Adults.

Nutrition education and food resource management (FRM) can assist food-insecure individuals in acquiring healthy and affordable food. We aimed to assess the relationships between FRM skills and healthy eating focus with diet quality and health-related behaviors in low-income adults during the COVID-19 pandemic. This cross-sectional study was conducted using an online survey of 276 low-income adults living in a low-food-access community in Northeast Connecticut. Through analysis of covariance, adults who usually or always had a meal plan, considered reading nutrition labels important, made a grocery list, were concerned about their food healthiness, and rated their diet quality as very good/excellent reported higher diet quality (frequency-based and liking-based scores) (p < 0.05 for all). Individuals who considered reading food labels very important and reported having a good diet reported less frequent pandemic-related unhealthy behaviors (consumption of candy and snack chips, soda or sugary drinks, weight gain, smoking) (p < 0.001). Furthermore, higher-frequency-based diet quality was associated with lower risk of overweight or obesity (OR: 0.37; 95% CI: 0.18, 0.76; p-trend < 0.01). Thus, FRM skills and healthy eating focus were associated with higher diet quality and healthier self-reported changes in diet, weight, and smoking behaviors during the pandemic.

Behavioral report of Chrysomya rufifacies in response to substrate infestation by Lucilia sericata and Lucilia cuprina using a tetrahedron olfactometer device.

Calliphoridae are widespread globally and can inhabit a variety of habitats. In this brief report, we assessed the appeal of Chrysomya rufifacies to resources that were previously inhabited by Lucilia sericata and L. cuprina, both common carrion colonizers. Two hundred adult male and female (1:1) C. rufifacies were released under controlled conditions into clear plastic cages (45 x 45 x 45 cm) with four types of substrates: beef-liver; liver with 100 third-instar larvae of L. cuprina; (III) liver containing 100 third-instar larvae of L. sericata; and liver containing 100 third-instar larvae of C. rufifacies. Each substrate was left in place for 24 hours at the end of a tube connected to the cage, where sticky traps were positioned to capture flies that might have been attracted to a specific substrate. The results indicate variations in the attraction of flies to different types of livers colonized by larvae of various species. It is suggested that flies may have specific preferences depending on the species of larvae present in the substrate. The liver without larvae was the preferred choice, while beef liver with C. rufifacies larvae was the least attractive. Results of statistical tests indicated that there is independence between attractiveness preference and the presence of C. rufifacies flies. Although there is a trend among certain levels of the variables in the correspondence analysis, these relationships are not statistically significant. However, they indicate specific patterns of association between different groups of flies and species of larvae. This study demonstrated that C. rufifacies does not show reduced attraction to any of the resources. A tetrahedron olfactometer device has been used for the first time in a behavioral study of C. rufifacies flies. This may enable future studies to enhance the understanding of fly behavior.

Synthetic biology for the food industry: advances and challenges.

As global environmental pollution increases, climate change worsens, and population growth continues, the challenges of securing a safe, nutritious, and sustainable food supply have become enormous. This has led to new requirements for future food supply methods and functions. The use of synthetic biology technology to create cell factories suitable for food industry production and renewable raw material conversion into: important food components, functional food additives, and nutritional chemicals, represents an important method of solving the problems faced by the food industry. Here, we review the recent progress and applications of synthetic biology in the food industry, including alternatives to: traditional (artificial pigments, meat, starch, and milk), functional (sweeteners, sugar substitutes, nutrients, flavoring agents), and green (green fiber, degradable packing materials, green packaging materials and food traceability) foods. Furthermore, we discuss the future prospects of synthetic biology-based applications in the food industry. Thus, this review may serve as a reference for research on synthetic biology in the: food safety, food nutrition, public health, and health-related fields.

Learning What Works: A Mixed-Methods Study of American Self-identified Food Conservers.

OBJECTIVE: Identify psychosocial factors influencing food waste mitigation and explore motivations and strategies for successful conservation among self-identified food conservers. METHODS: Mixed-methods study consisting of an online survey estimating food waste production and psychosocial factors and a focus group to explore waste mitigation strategies and motivations. RESULTS: Sampled 27 self-identified conservers (female, aged 18-30 years, White/Asian). Mean household food waste was 6.6 cups/wk (range, 0.0-97.9 cups/wk; median 1.3 cups). Reported waste mitigation strategies include proactive mitigation and adaptive recovery measures in each phase of the food management continuum. Conservers reported various intrinsic and extrinsic motivations to reduce food waste and viewed barriers as manageable. CONCLUSIONS AND IMPLICATIONS: Food conservers act on high intentions to reduce waste by consistently employing both proactive waste mitigation and adaptive food recovery measures. Future research is needed to determine if these findings hold in larger, more diverse samples and link specific behaviors to waste volume.

Patterns of use of wild food plants by Brazilian local communities: systematic review and meta-analysis.

BACKGROUND: This systematic review and meta-analysis sought to investigate the patterns of use of native wild food plants of Brazil (native and non-cultivated). METHODS: We searched ethnobiological works with food plants in Web of Science, Scielo, Scopus and PubMed using different sets of keywords. Initially, the studies were evaluated based on inclusion criteria (systematic data collection instruments, such as interviews; specification of methods for data collection; and the presence of a species list). The methodological quality of each study was evaluated to define the risk of bias. A total of 20 articles met all criteria and were included in the review. RESULTS: The results showed that there was a predominance of consumption of fruits, followed by leaves and seeds, which together represented 85.8% of the total parts. As for the meta-analysis, there was a predominance of use of plant parts classified as reproductive, non-persistent, non-destructive and parts of woody plants. There was no interference from the type of ecosystem (seasonally dry x moist). The results did not support the seasonality hypothesis. CONCLUSIONS: The concentration of studies in the Northeast, Southeast and South regions of Brazil and in the Atlantic Forest and Caatinga biomes points to the need for a greater effort in terms of quantitative ethnobotanical research in other regions and biomes. The predominance of fruits and plant parts classified as reproductive, non-persistent and non-destructive points to the high potential for implementation of sustainable management strategies aimed at these plants in the country.

The structure characteristics, biosynthesis and health benefits of naturally occurring rare flavonoids.

Rare flavonoids, a special subclass of naturally occurring flavonoids with diverse structures including pterocarpans, aurones, neoflavonoids, homoisoflavones, diphenylpropanes, rotenoids and 2-phenylethyl-chromones. They are mainly found in legumes with numerous health benefits. Rare flavonoids are regarded as minor flavonoids due to their very limited abundance in nature. This review gives an overview of the natural occurrences of rare flavonoids from previous literatures. Recent findings on the biosynthesis of rare flavonoids have been updated by describing their structural characteristics and classifications. Recent findings on the health benefits of rare flavonoids have also been compiled and discussed. Natural rare flavonoids with various characteristics from different subclasses from plant-based food sources are stated. They show a wide range of health benefits, including antibacterial, anticancer, anti-osteoporosis and antiviral activities. Studies reviewed suggest that rare flavonoids possessing different skeletons demonstrate different characteristic bioactivities by discussing their mechanism of actions and structure-activity relationships. Besides, recent advances on the biosynthesis of rare flavonoids, such as pterocarpans, rotenoids and aurones are well-known, while the biosynthesis of other subclasses remain unknown. The perspectives and further applications of rare flavonoids using metabolic engineering strategies also be expected.

Community-based nutrition education and hands-on cooking intervention increases farmers' market use and vegetable servings.

OBJECTIVE: The objective of the current study was to evaluate the impact of the Market to MyPlate (M2MP) program on participants' reported farmers' market (FM) attitudes and shopping behaviours, frequency of serving vegetables to their families, food resource management behaviours and food security. A secondary objective was to identify facilitators and barriers to shopping at FM and food waste reduction techniques used by low-income families. DESIGN: The current study used a mixed methods evaluation embedded within a cluster randomised trial of the M2MP intervention. SETTING: The 7-week M2MP program was delivered at Extension offices and community centres in central Illinois. PARTICIPANTS: Participants included 120 adults and their families. Class cohorts were randomly assigned to one of three treatment groups: (1) nutrition education and cooking classes with produce allocations (PAE, n 39); (2) nutrition education and cooking classes only (EO, n 36) or (3) control group (n 45). RESULTS: Compared with control participants, PAE participants were significantly more likely to report shopping at FM (P = 0·029) and reported serving more vegetables to their families (P = 0·010) (EO participants did not differ from the control group on any outcomes). There were no differences between conditions in survey-based measures of food security or food resource management behaviours. Interview results describe facilitators and barriers to shopping at FM and a variety of food waste reduction techniques (including food placement and food resource management). CONCLUSIONS: These findings suggest that fresh produce provision coupled with nutrition and culinary education can positively impact shopping and dietary behaviours.

Feasibility of Using Facebook to Engage SNAP-Ed Eligible Parents and Provide Education on Eating Well on a Budget.

This study examined the use of Facebook to provide education on food resource management and healthy eating on a budget to parents of preschool aged children participating in Head Start. A convenience sample of 25 parents participated in a Facebook group based on Sesame Street's Food for Thought: Eating Well on a Budget curriculum over a 3-week period. Parent engagement was assessed by examining views, likes, and comments on posts. Qualitative data were used to assess knowledge, attitudes, and barriers experienced related to healthy eating on a budget. The results suggest that parents were engaged throughout the intervention, as evidenced by views, likes, and comments on Facebook posts, as well as by study retention (90%). Interactions with the intervention materials varied by post content, with discussion questions having the highest level of interaction. Facebook was found to be a feasible platform for delivering the intervention, and the Facebook-adapted version of the Sesame Street curriculum was shown to engage Head Start parents living in rural areas. Further research should explore the use of social media platforms for delivering nutrition education interventions to rural populations that are otherwise difficult to reach.

Development of Reliable and Valid Questions to Assess Food Resource Management Behaviors in Adults With Limited Income.

OBJECTIVE: Develop reliable, valid questions to assess changes in food resource management (FRM) behaviors in adults with limited incomes. DESIGN: Questionnaire development using a mixed-methods approach: content validity (subject matter and curricula), face validity, temporal reliability (test-retest), sensitivity to change, and exploratory factor analysis (EFA). SETTING: Community settings in 12 states. PARTICIPANTS: Convenience samples of English-speaking Expanded Food and Nutrition Education Program (EFNEP) or EFNEP-eligible adults: 105 (cognitive interviews), 181 (test-retest), 185 (sensitivity), and 389 (EFA) adults. VARIABLES MEASURED: Behaviors related to FRM skills: planning, shopping, and budgeting. ANALYSIS: Consistency and agreement in cognitive interviews and temporal reliability; sensitivity at posttest (paired t tests, Wilcoxon signed-rank tests); internal consistency of scales identified in EFA (Cronbach α). P < 0.5. RESULTS: All questions had acceptable temporal reliability ranges for the intraclass correlation coefficient (0.48-0.74) and Spearman rank-order correlation (0.48-0.73). All questions were sensitive to change at posttest (P < 0.001). Planning and saving scales, revealed by EFA, demonstrated internal consistency (> 0.80 Cronbach α). CONCLUSIONS AND IMPLICATIONS: The 9 FRM behavior questions have acceptable temporal reliability and content and face validity and can be used nationally by EFNEP to assess participants' self-reported behavior changes. Other nutrition programs with similar audiences and content could use these questions to measure changes in FRM behaviors.

Prenylated flavonoids in foods and their applications on cancer prevention.

Functional foods play an important role in health care and chronic diseases prevention, particularly cancer. Prenylated flavonoids are presented in many food resources. They are recognized as neutraceuticals due to their diverse health benefits. Up to now, more than 1000 prenylated flavonoids have been identified in plants. Their food resources are reviewed in this paper. Due to the good safety and cancer prevention effect of prenylated flavonoids, this paper reviews the cancer prevention activities and mechanisms reported in last decade. The structure-activity relationship is discussed. Due to the limited availability in nature, the heterologously biosynthetic technique of prenylated flavonoids is discussed in this review. Inclusion of dietary prenylated flavonoids into human diet is highly desirable. This paper combines the up-to-date information and give a clear image regarding prenylated flavonoids as neutraceuticals.

Structure, properties and potential bioactivities of high-purity insoluble fibre from soybean dregs (Okara).

High-purity insoluble dietary fibre (HPIDF) was obtained from low-purity dietary fibre (LPDF) of Okara using a combined-enzyme method. For exploring the value of HPIDF as a functional food material, the structure, physicochemical properties, adsorption properties, potential bioactivities of HPIDF and their changes in different stages of digestion were explored in vitro. The results show that HPIDF shows a high perfect oil-holding capacity, higher viscosity, better cation exchange capacity, α-amylase activity ratio due to smaller particle size and larger specific surface area. The heavy metals-adsorption (Cd2+, Pb2+, Zn2+) shows the same, especially in simulated gastric fluid, which is similar to the adsorbability of glucose, cholesterol and acrylamide. Beyond the structure, the dissociation degree of some functional groups result from different digestive environments is the possible cause. Okara is an ideal material for the recovery of HPIDF, which has the potential to be processed into functional food materials.

Gut microbiomes of bigheaded carps and hybrids provide insights into invasion: A hologenome perspective.

Gut microbiomes play an essential role in host survival and local adaptation and thus can facilitate the invasion of host species. Biological invasions have been shown to be linked to the genetic properties of alien host species. It is thus plausible that the holobiont, the host, and its associated microbiome act as an entity to drive invasion success. The bighead carp and silver carp (bigheaded carps), invasive species that exhibit extensive hybridization in the Mississippi River Basin (MRB), provided a unique model to test the holobiont hypothesis of invasion. Here, we investigated the microbiomes of foreguts and hindguts in bigheaded carps and their reciprocal hybrids reared in aquaculture ponds using 16S amplicons and the associated gene prediction. We found an admixed pattern in the gut microbiome community in bigheaded carp hybrids. The hybrid gut microbiomes showed special characteristics such as relatively high alpha diversity in the foregut, an increasing dissimilarity between foreguts and hindguts, and a remarkable proportion of genes coding for putative enzymes related to their digestion of main food resources (Cyanobacteria, cellulose, and chitin). The pond-reared hybrids had advantageous features in genes coding for putative enzymes related to their diet. The above results collectively suggested that the gut microbiomes of hybrids could be beneficial to their local adaptation (e.g., food resource utilization), which might have facilitated their invasion in the MRB. The gut microbial findings, along with the intrinsic genomic features likely associated with life-history traits revealed in our recent study, provide preliminary evidence supporting the holobiont hypothesis of invasion.

Head Start Parents With or Without Food Insecurity and With Lower Food Resource Management Skills Use Less Positive Feeding Practices in Preschool-Age Children.

BACKGROUND: Food resource management (FRM), strategies to stretch limited food resource dollars, may mitigate the impact of household food insecurity (HFI) on family members, including young children. However, little is known about how FRM and HFI are associated with child feeding practices. OBJECTIVES: The study aimed to explore relationships between HFI, FRM, and child feeding practices of low-income parents. METHODS: In a cross-sectional sample of 304 Head Start households, caregivers completed the USDA HFI module [classifying them as either food secure (FS) or food insecure (FI)], FRM behavior subscale (classifying them as being high or low in management skills based on a median score split), Comprehensive Feeding Practices Questionnaire, and Perceived Stress Scale. Households were categorized into 4 HFI-FRM subgroups: FS/high FRM (30.6%), FS/low FRM (31.3%), FI/high FRM (18.8%), and FI/low FRM (19.4%). Multivariable linear regression was used to examine whether feeding practices differed across HFI-FRM categories and whether the addition of parental perceived stress contributed to differences in feeding practices by HFI-FRM group. RESULTS: In our study, 38% of households were FI. Compared to the FS/high FRM group in the adjusted models, the FS/low FRM group used less monitoring (-0.53; 95% CI: -0.78 to -0.28), modeling (-0.38; 95% CI: -0.64 to -0.13), and involvement (-0.57; 95% CI: -0.82 to -0.32) in feeding. A similar pattern emerged for the FI/low FRM group. The use of food as a reward was higher in the FI/high FRM (0.35; 95% CI: 0.02-0.67) and FI/low FRM groups (0.33; 95% CI: 0.01-0.66) compared to the FS/high FRM group. Perceived stress was positively associated with the use of negative, controlling feeding practices, and contributed to differences in using food as a reward within the HFI-FRM group. CONCLUSIONS: Suboptimal child feeding is evident in low-income caregivers with low FRM skills, with or without food insecurity. Promoting high FRM skills, in addition to addressing food insecurity, could potentially synergistically improve child feeding practices in low-income households.

Food Resource Management Mediates the Relationship Between Participation in a SNAP-Ed Nutrition Education Program and Diet Quality.

OBJECTIVE: To examine the mediating effects of food resource management skills (FRM) on the relationship between participation in a Supplemental Nutrition Assistance Program Education (SNAP-Ed) nutrition education program and diet quality. DESIGN: Secondary analysis of data from a propensity score-matched sample of participants (n = 396) and nonparticipants (n = 111) in a SNAP-Ed nutrition education program. ANALYSIS: Independent-samples t tests were used to compare entry, exit, and gain scores in FRM and diet quality between participants and nonparticipants. Structural equation modeling was used to examine direct and mediated relationships among participation, FRM, and diet quality. MAIN OUTCOME MEASURES: Food resource management was measured as a summated rating scale, and diet quality measured as Healthy Eating Index and program participation. RESULTS: Mediated effect of FRM on the relationship between participation in a SNAP-Ed program and diet quality was statistically significant (P < 0.01). The effect size for the mediation effect indicated that about 70% of program participation on diet quality was transferred by FRM skills. The hypothesized model had acceptable fit indices as model χ2 was nonsignificant (P = 0.31), all fit indices were above 0.9, and the root mean square of error approximation was low at 0.02. CONCLUSIONS AND IMPLICATIONS: Participation in a SNAP-Ed program enhanced participants' FRM, which in turn enhanced their diet quality.

Caregiver's Self-Confidence in Food Resource Management Is Associated with Lower Risk of Household Food Insecurity among SNAP-Ed-Eligible Head Start Families.

Food resource management (FRM) behaviors are key components within nutrition education programs designed to help food insecure households maximize their food dollars. However, little is known about the association between FRM self-confidence and financial practices with household food insecurity (HFI) among families with young children. Using a sample of SNAP-Ed-eligible Head Start families, this study examined associations between FRM self-confidence, FRM behaviors and financial practices by HFI. A needs assessment survey was conducted with caregivers of Head Start children (n = 365). HFI was measured using the US Household Food Security Survey Module. Chi-square and logistic regression analyses were conducted to examine if FRM self-confidence, FRM behaviors, and financial practices differed by HFI. Participants with high FRM self-confidence had lower odds of HFI (OR = 0.54, 95%CI: 0.33, 0.87), yet FRM behaviors, financial practices, and HFI were not related after adjusting for covariates. All FRM self-confidence questions significantly differed by HFI, whereas only one of six FRM behaviors and two of three financial practices differed by HFI (all p-values < 0.05). Promoting caregivers' self-confidence in FRM skills within nutrition education programs may be explored as a potential strategy to assist low-income households to stretch their food dollars in an attempt to address HFI.

Nutritional Value of the Larvae of the Alien Invasive Wasp Vespa velutina nigrithorax and Amino Acid Composition of the Larval Saliva.

The systematic investigations on the value of social wasps as a food resource are deficient, in spite of the long history of the utilization of social wasps as food and pharmaceutical bioresources. Vespa velutina nigrithorax is an invasive alien wasp species that is currently dominating in East Asia and Europe, bringing huge economic damages. As a control over alien species is made when the valuable utilization of the invasive species as a potential resource are discovered, investigations on the potential of V. v. nigrithorax as a useful bioresource are also in demand. Nutritional and heavy metal analyses of the larvae revealed their balanced and rich nutritional value and safety as a food resource. The larval saliva amino acid composition was investigated for further study on amino acid supplementation and exercise enhancement.

Responses of macroinvertebrate communities to land use specific sediment food and habitat characteristics in lowland streams.

The input of land use specific organic matter into lowland streams may impact sediment characteristics in terms of food resources and habitat structure, resulting in differences in macroinvertebrate community composition. Therefore, we investigated to what extent land use specific sediment food and habitat characteristics structure macroinvertebrate communities. To this purpose linear multiple regression models were constructed, in which macroinvertebrate biotic indices were considered as response variables and sediment characteristics as predictor variables, analysed in 20 stream stretches running through five different land use types. Sediment characteristics and macroinvertebrate community composition were land use specific. The carbon/nitrogen (C/N) ratio, woody debris substrate cover and the origin of fatty acids influenced macroinvertebrate community composition. Shannon-Wiener diversity was better explained by fatty acids origin, such as in grassland streams, where a higher relative content of plant derived fatty acids related to a higher macroinvertebrate diversity. In cropland and wastewater treatment plant (WWTP) streams with a low C/N ratio and dominated by microbial derived fatty acids, higher abundances of Oligochaeta and Chironomus sp. were observed. Ephemeroptera, Plecoptera, and Trichoptera (EPT) richness was positively related to woody debris substrate cover, which only occurred in forest streams. Hence, macroinvertebrate community composition was influenced by the origin of the organic material, being either allochthonous or autochthonous and when autochthonous being either autotrophic or heterotrophic. It is therefore concluded that sediment food and habitat characteristics are key ecological filters.

Red-crowned crane (Grus japonensis) prefers postharvest reed beds during winter period in Yancheng National Nature Reserve.

Reed beds represent an important habitat for the survival of birds by providing favorable foraging and reproduction conditions. Reed management, as a traditional agricultural activity, primarily includes water level control and vegetation removal by cutting. Red-crowned crane (Grus japonensis) is one of the most endangered cranes, and their population continues to decline due to habitat loss caused by artificial activities. A lack of research relating to how reed management affects crane habitat distribution patterns throughout the wintering period hinders our ability to offer conservation recommendations. In the present study, we explored the effect of reed management on the habitat distribution patterns and analyzed the food resources of red-crowned crane in the Yancheng National Nature Reserve (YNNR). According to the reed management activities in December, we divided the wintering period into two phases: the preharvest period and the postharvest period. Throughout the wintering period, the number of cranes recorded in the common seepweed (Suaeda glauca) tidal flats remained stable, but cranes were rarely recorded in the smooth cordgrass (Spartina alterniflora) tidal flats and aquaculture fish ponds. The number of cranes, however, showed a noticeable fluctuation in the reed beds during the two periods. Before the reed harvest, only a small proportion of cranes were recorded in the reed beds (relative abundance = 2.9%). However, more cranes (relative abundance = 61.0%) were recorded after the reed harvest. Water was introduced from adjacent rivers and fish ponds to submerge the cut reed beds. Changes in potential animal food resources (items and biomass) might be one of the vital reasons for the preference of cranes to the postharvest reed beds. Our results suggest that traditional reed management in the YNNR could benefit this flagship crane species that winters in the wetland system. However, as reed harvest has been forbidden in the core zone for conservation purposes since 2016, further research is needed to verify whether forbidding the harvest of reeds is reasonable.

Safety and quality of the green tide algal species Ulva prolifera for option of human consumption: A nutrition and contamination study.

This study sampled U. prolifera and surface seawater from the same locations where green tide broke out in the southern Yellow Sea, in both the year 2016 and 2017. The revealed nutritive components of U. prolifera samples characterized U. prolifera as a high-protein, high-Fe, high ratio of unsaturated lipid acids and low-fat seaweed food, with an ideal ratio of essential and nonessential amino acids. The concentrations and health risk assessment of major micropollutants (heavy metals, pesticides and polycyclic aromatic hydrocarbon (PAHs)) in U. prolifera were also analyzed, respectively. The results showed that the Target Hazard Quotient values of five heavy metals (<1.0 × 10-1) and the total hazard index of 13 pesticides (<1.5 × 10-8) were lower than the unity, respectively, and the incremental lifetime cancer risk values of PAHs (<7.4 × 10-7) were lower than the USEPA limit (1.0 × 10-6). It suggested that consuming U. prolifera is safe as a food-source option, with PAHs causing relatively higher risks. PAHs from the sites closer to the shore were also found more originated from pyrolysis. We further confirmed the PAH congeners were partly in equilibrium between seawater and U. prolifera. It suggested the possibility that the food safety-risk turned to be above the USEPA limit was not high regardless of the sample collecting time. However, the sources of PAHs and their contributions to the accumulation in U. prolifera need further investigation. This study favored that U. prolifera of the green tide from the southern Yellow Sea has a potential for a nutritious-food production.

Healthy Choices for Every Body Adult Curriculum Improves Participants' Food Resource Management Skills and Food Safety Practices.

OBJECTIVE: To evaluate the impact of the University of Kentucky's Healthy Choices for Every Body (HCEB) adult nutrition education curriculum on participants' food resource management (FRM) skills and food safety practices. METHODS: A quasi-experimental design was employed using propensity score matching to pair 8 intervention counties with 8 comparison counties. Independent-samples t tests and ANCOVA models compared gains in FRM skills and food safety practices between the intervention and comparison groups (n = 413 and 113, respectively). RESULTS: Propensity score matching analysis showed a statistical balance and similarities between the comparison and intervention groups. Food resource management and food safety gain scores were statistically significantly higher for the intervention group (P < .001), with large effect sizes (d = 0.9) for both variables. The group differences persisted even after controlling for race and age in the ANCOVA models. CONCLUSIONS AND IMPLICATIONS: The HCEB curriculum was effective in improving the FRM skills and food safety practices of participants.
