Development and evaluation of the Food Bank Health and Nutrition Assessment.

OBJECTIVE: Efforts to improve the nutritional quality and health promotion in the charitable food system have been undertaken. Though methods exist to track these efforts in terms of food banks' inventory, there are not research-tested tools to assess, monitor and influence policy, systems and environmental (PSE) changes. The study objective was to develop and evaluate a novel assessment tool that could be used to evaluate a food bank's efforts to improve the promotion of health and nutritious foods. DESIGN: The study had five phases: (1) initial development; (2) iterative review and revisions; (3) pilot testing; (4) content validity assessment and (5) inter-rater and test-retest assessment. The Food Bank Health and Nutrition Assessment (FB-HANA) was drafted after reviewing existing policies, nutrition-focused charitable food systems guidance and similar tools for food pantries. SETTING: Midwestern United States. PARTICIPANTS: Eleven food banks. RESULTS: Stakeholders and pilot testers provided initial feedback to refine the FB-HANA's flow, ease of completion and collection of contextual information. External experts rated the FB-HANA and each of the eight objectives as content valid. A set of two assessments completed by twenty-six community-based professionals, employed by Extension and fourteen food bank staff across eleven food banks, supported moderate to excellent inter-rater and test-retest reliability for the FB-HANA overall and each of its objectives. CONCLUSIONS: Evidence suggests that the FB-HANA can be used by either food bank or community-based professionals, such as Extension staff, to provide a perspective on ways food banks promote health and nutrition through PSE approaches.

Customized optical mapping by CRISPR-Cas9 mediated DNA labeling with multiple sgRNAs.

Whole-genome mapping technologies have been developed as a complementary tool to provide scaffolds for genome assembly and structural variation analysis (1,2). We recently introduced a novel DNA labeling strategy based on a CRISPR-Cas9 genome editing system, which can target any 20bp sequences. The labeling strategy is specifically useful in targeting repetitive sequences, and sequences not accessible to other labeling methods. In this report, we present customized mapping strategies that extend the applications of CRISPR-Cas9 DNA labeling. We first design a CRISPR-Cas9 labeling strategy to interrogate and differentiate the single allele differences in NGG protospacer adjacent motifs (PAM sequence). Combined with sequence motif labeling, we can pinpoint the single-base differences in highly conserved sequences. In the second strategy, we design mapping patterns across a genome by selecting sets of specific single-guide RNAs (sgRNAs) for labeling multiple loci of a genomic region or a whole genome. By developing and optimizing a single tube synthesis of multiple sgRNAs, we demonstrate the utility of CRISPR-Cas9 mapping with 162 sgRNAs targeting the 2Mb Haemophilus influenzae chromosome. These CRISPR-Cas9 mapping approaches could be particularly useful for applications in defining long-distance haplotypes and pinpointing the breakpoints in large structural variants in complex genomes and microbial mixtures.

Distribution of fresh foods in food pantries: challenges and opportunities in Illinois during the COVID-19 pandemic.

BACKGROUND: The charitable food system distributes free food to clients across the U.S., but many nutrition and health-focused efforts encounter barriers to success, which were exacerbated during the COVID-19 pandemic. The objective of the current study was to understand barriers and facilitators to distributing nutritious, fresh foods in food pantries across Illinois during the COVID-19 pandemic. METHODS: Forty-nine pantry representatives participated in focus groups in October 2021. A codebook was created based on relevant literature, stakeholder interests, and an initial review of the recordings. Transcripts of each group were coded and analyzed using a basic interpretive approach. RESULTS: Pantries distribution of fresh foods was impacted by community partners, food bank policies and practices, and the quality of the donated fresh foods. Physical constraints of pantries limit fresh food storage capacity. The COVID-19 pandemic magnified stressors in the charitable food system which highlighted how community partners might improve fresh food distribution. CONCLUSION: Focus groups with food pantry representatives across Illinois provided key insights that can inform future efforts to facilitate fresh food distribution in the charitable food system. Future studies should evaluate the effects of the suggested initiatives and changes at the food pantry, food bank, and policy levels.

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.

Community-based culinary and nutrition education intervention promotes fruit and vegetable consumption.

OBJECTIVE: The main objective of this study was to evaluate the impact of the Market to MyPlate (M2MP) program on fruit and vegetable consumption and cooking behaviours. Secondary objectives were to examine factors that affected participant retention and program completion, and analyse program feedback provided by participants. DESIGN: This study conducted a mixed methods evaluation embedded within a cluster randomised controlled trial of the M2MP intervention. Adult participants completed a pre- and post-program survey reporting on their fruit and vegetable consumption and cooking behaviours. A subsample participated in structured interviews, providing feedback about M2MP and the impact of the program. SETTING: Seven weekly classes took place in community centres and extension offices in central Illinois. PARTICIPANTS: 120 adults and their families participated. 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 to control, PAE participants reported larger increases from pre- to post-intervention in fruit (P = 0·001) and vegetable consumption (P = 0·002), with no differences in cooking frequency. Interview analyses identified key themes in behaviour changes due to M2MP, including reported increases in dietary variety, cooking self-efficacy and children's participation in cooking. CONCLUSIONS: PAE participants who received an intervention that directly increased their access to fresh produce (via produce allocations) increased their reported fruit and vegetable consumption. Though participants' cooking frequency did not change, interviewees reported increased variety, cooking confidence and family participation in cooking.

Whole egg consumption and cognitive function among US older adults.

BACKGROUND: Eggs are an affordable food providing many shortfall nutrients with the potential to improve cognitive health. We assessed the relationship between whole egg consumption and cognitive functioning among a US nationally representative sample of older adults. METHODS: Individual-level data (2816 adults, aged ≥ 60 years) were obtained from the National Health and Nutrition Examination Survey (NHANES) 2011-2012 and 2013-2014 waves. Cognitive assessments included the Consortium to Establish a Registry for Alzheimer's Disease Word List Learning Test (CERAD-WL), Word List Recall Test (CERAD-DR), Animal Fluency Test (AF) and Digit Symbol Substitution Test (DSST). A composite cognitive z-score was constructed based on the individual tests to represent one's overall cognitive functioning. Multiple linear and logistic regressions were performed to examine the effect of whole egg consumption on cognitive functioning, adjusting for individual characteristics and survey design. RESULTS: Approximately 57% of older adults consumed whole eggs, with an average daily intake of 34 g of whole egg equivalent among consumers. The average z-scores of the CERAD-WL, CERAD-DR, AF and DSST tests were -0.08, 0.23, 0.37 and 0.42, respectively, and the overall composite cognitive z-score was 0.24 among older adults. Regression analyses found that neither whole egg consumption status, nor daily intake quantity was associated with cognitive test scores. CONCLUSIONS: No association was found between whole egg consumption and cognitive functioning among US older adults. Study limitations included cross-sectional study design and measurement errors. Future studies with longitudinal or experimental design are warranted to examine the possible link between egg consumption and cognition in older adults.

Single-molecule analysis of subtelomeres and telomeres in Alternative Lengthening of Telomeres (ALT) cells.

BACKGROUND: Telomeric DNA is typically comprised of G-rich tandem repeat motifs and maintained by telomerase (Greider CW, Blackburn EH; Cell 51:887-898; 1987). In eukaryotes lacking telomerase, a variety of DNA repair and DNA recombination based pathways for telomere maintenance have evolved in organisms normally dependent upon telomerase for telomere elongation (Webb CJ, Wu Y, Zakian VA; Cold Spring Harb Perspect Biol 5:a012666; 2013); collectively called Alternative Lengthening of Telomeres (ALT) pathways. By measuring (TTAGGG) n tract lengths from the same large DNA molecules that were optically mapped, we simultaneously analyzed telomere length dynamics and subtelomere-linked structural changes at a large number of specific subtelomeric loci in the ALT-positive cell lines U2OS, SK-MEL-2 and Saos-2. RESULTS: Our results revealed loci-specific ALT telomere features. For example, while each subtelomere included examples of single molecules with terminal (TTAGGG) n tracts as well as examples of recombinant telomeric single molecules, the ratio of these molecules was subtelomere-specific, ranging from 33:1 (19p) to 1:25 (19q) in U2OS. The Saos-2 cell line shows a similar percentage of recombinant telomeres. The frequency of recombinant subtelomeres of SK-MEL-2 (11%) is about half that of U2OS and Saos-2 (24 and 19% respectively). Terminal (TTAGGG) n tract lengths and heterogeneity levels, the frequencies of telomere signal-free ends, and the frequency and size of retained internal telomere-like sequences (ITSs) at recombinant telomere fusion junctions all varied according to the specific subtelomere involved in a particular cell line. Very large linear extrachromosomal telomere repeat (ECTR) DNA molecules were found in all three cell lines; these are in principle capable of templating synthesis of new long telomere tracts via break-induced repair (BIR) long-tract DNA synthesis mechanisms and contributing to the very long telomere tract length and heterogeneity characteristic of ALT cells. Many of longest telomere tracts (both end-telomeres and linear ECTRs) displayed punctate CRISPR/Cas9-dependent (TTAGGG) n labeling patterns indicative of interspersion of stretches of non-canonical telomere repeats. CONCLUSION: Identifying individual subtelomeres and characterizing linked telomere (TTAGGG) n tract lengths and structural changes using our new single-molecule methodologies reveals the structural consequences of telomere damage, repair and recombination mechanisms in human ALT cells in unprecedented molecular detail and significant differences in different ALT-positive cell lines.

High-throughput single-molecule telomere characterization.

We have developed a novel method that enables global subtelomere and haplotype-resolved analysis of telomere lengths at the single-molecule level. An in vitro CRISPR/Cas9 RNA-directed nickase system directs the specific labeling of human (TTAGGG)n DNA tracts in genomes that have also been barcoded using a separate nickase enzyme that recognizes a 7-bp motif genome-wide. High-throughput imaging and analysis of large DNA single molecules from genomes labeled in this fashion using a nanochannel array system permits mapping through subtelomere repeat element (SRE) regions to unique chromosomal DNA while simultaneously measuring the (TTAGGG)n tract length at the end of each large telomere-terminal DNA segment. The methodology also permits subtelomere and haplotype-resolved analyses of SRE organization and variation, providing a window into the population dynamics and potential functions of these complex and structurally variant telomere-adjacent DNA regions. At its current stage of development, the assay can be used to identify and characterize telomere length distributions of 30-35 discrete telomeres simultaneously and accurately. The assay's utility is demonstrated using early versus late passage and senescent human diploid fibroblasts, documenting the anticipated telomere attrition on a global telomere-by-telomere basis as well as identifying subtelomere-specific biases for critically short telomeres. Similarly, we present the first global single-telomere-resolved analyses of two cancer cell lines.

Genome rearrangements induce biofilm formation in Escherichia coli C - an old model organism with a new application in biofilm research.

BACKGROUND: Escherichia coli C forms more robust biofilms than other laboratory strains. Biofilm formation and cell aggregation under a high shear force depend on temperature and salt concentrations. It is the last of five E. coli strains (C, K12, B, W, Crooks) designated as safe for laboratory purposes whose genome has not been sequenced. RESULTS: Here we present the complete genomic sequence of this strain in which we utilized both long-read PacBio-based sequencing and high resolution optical mapping to confirm a large inversion in comparison to the other laboratory strains. Notably, DNA sequence comparison revealed the absence of several genes thought to be involved in biofilm formation, including antigen 43, waaSBOJYZUL for lipopolysaccharide (LPS) synthesis, and cpsB for curli synthesis. The first main difference we identified that likely affects biofilm formation is the presence of an IS3-like insertion sequence in front of the carbon storage regulator csrA gene. This insertion is located 86 bp upstream of the csrA start codon inside the - 35 region of P4 promoter and blocks the transcription from the sigma32 and sigma70 promoters P1-P3 located further upstream. The second is the presence of an IS5/IS1182 in front of the csgD gene. And finally, E. coli C encodes an additional sigma70 subunit driven by the same IS3-like insertion sequence. Promoter analyses using GFP gene fusions provided insights into understanding this regulatory pathway in E. coli. CONCLUSIONS: Biofilms are crucial for bacterial survival, adaptation, and dissemination in natural, industrial, and medical environments. Most laboratory strains of E. coli grown for decades in vitro have evolved and lost their ability to form biofilm, while environmental isolates that can cause infections and diseases are not safe to work with. Here, we show that the historic laboratory strain of E. coli C produces a robust biofilm and can be used as a model organism for multicellular bacterial research. Furthermore, we ascertained the full genomic sequence of this classic strain, which provides for a base level of characterization and makes it useful for many biofilm-based applications.

A systematic review of food pantry-based interventions in the USA.

OBJECTIVE: Food pantries play a critical role in combating food insecurity. The objective of the present work was to systematically review and synthesize scientific evidence regarding the effectiveness of food pantry-based interventions in the USA. DESIGN: Keyword/reference search was conducted in PubMed, Web of Science, Scopus, Cochrane Library and CINAHL for peer-reviewed articles published until May 2018 that met the following criteria. SETTING: food pantry and/or food bank in the USA; study design: randomized controlled trial (RCT) or pre-post study; outcomes: diet-related outcomes (e.g. nutrition knowledge, food choice, food security, diet quality); study subjects: food pantry/bank clients. RESULTS: Fourteen articles evaluating twelve distinct interventions identified from the keyword/reference search met the eligibility criteria and were included in the review. Five were RCT and the remaining seven were pre-post studies. All studies found that food pantry-based interventions were effective in improving participants' diet-related outcomes. In particular, the nutrition education interventions and the client-choice intervention enhanced participants' nutrition knowledge, cooking skills, food security status and fresh produce intake. The food display intervention helped pantry clients select healthier food items. The diabetes management intervention reduced participants' glycaemic level. CONCLUSIONS: Food pantry-based interventions were found to be effective in improving participants' diet-related outcomes. Interventions were modest in scale and usually short in follow-up duration. Future studies are warranted to address the challenges of conducting interventions in food pantries, such as shortage in personnel and resources, to ensure intervention sustainability and long-term effectiveness.

High-throughput single-molecule mapping links subtelomeric variants and long-range haplotypes with specific telomeres.

Accurate maps and DNA sequences for human subtelomere regions, along with detailed knowledge of subtelomere variation and long-range telomere-terminal haplotypes in individuals, are critical for understanding telomere function and its roles in human biology. Here, we use a highly automated whole genome mapping technology in nano-channel arrays to analyze large terminal human chromosome segments extending from chromosome-specific subtelomere sequences through subtelomeric repeat regions to terminal (TTAGGG)n repeat tracts. We establish detailed maps for subtelomere gap regions in the human reference sequence, detect many new large subtelomeric variants and demonstrate the feasibility of long-range haplotyping through segmentally duplicated subtelomere regions. These features make the method a uniquely valuable new tool for improving the quality of genome assemblies in complex DNA regions. Based on single molecule mapping of telomere-terminal DNA fragments, we provide proof of principle for a novel method to estimate telomere lengths linked to distinguishable telomeric haplotypes; this single-telomere genotyping method may ultimately enable delineation of human cis elements involved in telomere length regulation.

CRISPR-CAS9 D10A nickase target-specific fluorescent labeling of double strand DNA for whole genome mapping and structural variation analysis.

We have developed a new, sequence-specific DNA labeling strategy that will dramatically improve DNA mapping in complex and structurally variant genomic regions, as well as facilitate high-throughput automated whole-genome mapping. The method uses the Cas9 D10A protein, which contains a nuclease disabling mutation in one of the two nuclease domains of Cas9, to create a guide RNA-directed DNA nick in the context of an in vitro-assembled CRISPR-CAS9-DNA complex. Fluorescent nucleotides are then incorporated adjacent to the nicking site with a DNA polymerase to label the guide RNA-determined target sequences. This labeling strategy is very powerful in targeting repetitive sequences as well as in barcoding genomic regions and structural variants not amenable to current labeling methods that rely on uneven distributions of restriction site motifs in the DNA. Importantly, it renders the labeled double-stranded DNA available in long intact stretches for high-throughput analysis in nanochannel arrays as well as for lower throughput targeted analysis of labeled DNA regions using alternative methods for stretching and imaging the labeled long DNA molecules. Thus, this method will dramatically improve both automated high-throughput genome-wide mapping as well as targeted analyses of complex regions containing repetitive and structurally variant DNA.

Promotoras and the Semantic Gap Between Latino Community Health Researchers and Latino Communities.

Promotoras are identified as a unique group of community health workers adept at reducing health disparities. This qualitative study was conducted to better understand perceptions of the term promotora, broadly used in research but not well documented in everyday Latina vocabulary. Six focus groups to better understand perceptions of the term promotora were conducted with 36 Latina women living in three nonmetropolitan areas in Illinois. Results suggest that Latina participants in the study do not understand the meaning of "promotora" in the same way as it is used in the literature. Latina participants understood "promotoras" as referring to people who sell or deliver information, or organize events in the community that are not necessarily related to health events or community health work. Furthermore, they usually understood the term to refer to paid work rather than volunteering. Results underscore the importance of being sensitive to Latinas' perceptions of community health terminology by assessing their context, needs, and expectations. These findings call researchers' attention to the need to educate certain Latino communities about the concept of promotoras, with implications for the implementation and dissemination of promotora-led community health programs, as the semantic discrepancy could affect the recruitment of promotoras as well as community participation in the programs they deliver.

Complex disposition of methylthioninium redox forms determines efficacy in tau aggregation inhibitor therapy for Alzheimer's disease.

Methylthioninium (MT) is a tau aggregation inhibitor with therapeutic potential in Alzheimer's disease (AD). MT exists in equilibrium between reduced [leucomethylthioninium (LMT)] and oxidized (MT(+)) forms; as a chloride salt [methylthioninium chloride (MTC), "methylene blue"], it is stabilized in its MT(+) form. Although the results of a phase 2 study of MTC in 321 mild/moderate AD subjects identified a 138-mg MT/day dose as the minimum effective dose on cognitive and imaging end points, further clinical development of MT was delayed pending resolution of the unexpected lack of efficacy of the 228-mg MT/day dose. We hypothesized that the failure of dose response may depend on differences known at the time in dissolution in simulated gastric and intestinal fluids of the 100-mg MTC capsules used to deliver the 228-mg dose and reflect previously unsuspected differences in redox processing of MT at different levels in the gut. The synthesis of a novel chemical entity, LMTX (providing LMT in a stable anhydrous crystalline form), has enabled a systematic comparison of the pharmacokinetic properties of MTC and LMTX in preclinical and clinical studies. The quantity of MT released in water or gastric fluid within 60 minutes proved in retrospect to be an important determinant of clinical efficacy. A further factor was a dose-dependent limitation in the ability to absorb MT in the presence of food when delivered in the MT(+) form as MTC. A model is presented to account for the complexity of MT absorption, which may have relevance for other similar redox molecules.

NEFPAT Plus: A Valid and Reliable Tool for Assessing the Nutrition Environment in Food Pantries.

OBJECTIVE: To develop a consumer nutrition environment assessment tool to assess policy, systems, and environmental initiatives that are implemented in food pantries, which incorporates recent national guidance, and evaluate its validity and reliability. SETTING: Illinois, US. DESIGN: This study had 4 phases: (1) tool revision, (2) pilot testing, (3) content validity assessment, and (4) interrater and test-retest reliability assessment. The original Nutrition Environment Food Pantry Assessment Tool (NEFPAT) was revised to incorporate evidence from updated guidelines and evidence. The NEFPAT+ was pilot-tested by 9 professionals at 5 food pantries. After revisions, 18 experts rated the content validity. Interrater and test-retest reliability was based on 2-4 professionals completing independent evaluations at 21 food pantries twice, 1 month apart. ANALYSIS: Content validity indices and intraclass correlation (ICC) coefficients for reliability estimates were compared with established thresholds. RESULTS: The NEFPAT+ was rated content valid by 94% of experts. The ICC for NEFPAT+ scores indicated excellent interrater reliability (ICC, 0.96; 99% confidence interval, 0.75-0.97) and good test-retest reliability (ICC: 0.80; 99% confidence interval, 0.60-0.92). CONCLUSIONS: Evidence supports the content validity, interrater reliability, and test-retest reliability of the NEFPAT+. Future studies can assess how NEFPAT+ scores relate to intervention outcomes and dietary behaviors.

Policy, Systems, and Environmental Changes in Child Nutrition Programs: A Systematic Literature Review.

The National School Lunch Program (NSLP) provides healthy food to millions of children annually. To promote increased lunch consumption, policy, systems, and environmental (PSE) change strategies are being implemented in child nutrition programs. An evaluation of the current evidence supporting PSE interventions in school nutrition programs is needed to facilitate evidence-based practices across the nation for programs. This systematic review aims to determine the quality and breadth of available evidence of the effectiveness of PSE strategies on the consumption and waste of fruits, vegetables, milk, and water in the NSLP. The inclusion criteria required studies to occur in a United States K-12 school setting, data collection after 2012, report consumption and waste findings for fruit, vegetable, milk, or water, and be an original research article. Articles included in the review are restricted to positive or neutral quality. Thirty studies are included, policy level (n = 4), systems level (n = 8), environmental level (n = 10), and multi-category (n = 8). Results from positively rated policy-level studies suggest that recess before lunch may increase milk consumption, whereas removing flavored milk may decrease consumption. System-level studies of offering vegetables first in isolation of other meal components and offering spiced vegetables compared with traditional preparations may increase vegetable consumption, and locally procuring produce may increase fruit and vegetable consumption. Environmental-level studies such as water promotion strategies such as placing cups near drinking fountains may increase water consumption. Improving the convenience, attractiveness, and palatability of fruits and vegetables may increase consumption. Future PSE research in child nutrition programs should incorporate implementation aides and metrics into their study designs to allow a better understanding of how to sustain interventions from the perspective of school nutrition professionals.

Nutrition Environment at Food Pantries Improves After Fresh Produce Donation Program.

OBJECTIVE: To evaluate the influence of the Growing Together Illinois fresh produce donation program and understand factors that affect produce distribution at participating food pantries. METHODS: In this intervention at 17 Illinois food pantries, Master Gardeners supported food donation gardens, and Supplemental Nutrition Assistance Program Education provided educational and environmental interventions to increase selection and use of fresh produce. This mixed-methods pre-post study assessed pantry characteristics and program impact via Nutrition Environment Food Pantry Assessment Tool evaluations, interview feedback from pantry staff, and structured pantry observations. RESULTS: Pantries experienced significant increases from preintervention to postintervention in providing various types of produce, marketing and nudging healthful products, providing additional resources, and total Nutrition Environment Food Pantry Assessment Tool scores. Participants had positive feedback about the program and educational interventions and reported the weekly timing of donations mitigated potential storage and spoilage issues. CONCLUSIONS AND IMPLICATIONS: Future research could focus on approaches to increase fresh produce in food pantries while supporting clients via nutrition and cooking education.

Evaluation of Preferences Among Students Participating in the US Department of Agriculture Fresh Fruit and Vegetable Program.

BACKGROUND: Improving children's fruit and vegetable (FV) preferences may be important as preferences can predict FV consumption. The purpose of this study was to evaluate FV preferences over time, with repeated experience, as part of the Fresh Fruit and Vegetable Program (FFVP). METHODS: Fruits (F; N = 28) and vegetables (V; N = 29) were distributed twice a week, over 35 weeks, at a participating FFVP school (N = 236 students, 12 teachers, K-2nd grade). Preference ratings using 3-point Likert scale were analyzed over 35 weeks. RESULTS: For 57 FVs rated for preference, ratings revealed that F had higher frequency of children choosing "I like it" than for V (78% F; 38.2% V; p < .05) and liking distribution was different between F and V (p < .001). Significant relations were found between liking and: (1) grade (r = -0.02, p = .02), and (2) time (r = -0.09, p < .001). Models indicated that V served (ß = -0.40), timepoint (ß = -0.07), and grade level (ß = -0.02) accounted for significant variance for preference ratings (R2  = 0.17, p < .001), indicating that preference ratings declined over time. CONCLUSIONS: Fruits were preferred over vegetables. Overall preference ratings were negatively impacted by time, grade level, and vegetables served. Being exposed one time to a variety of FVs did not improve ratings for vegetables.

Technical Assistance is Related to Improvements in the Food Pantry Consumer Nutrition Environment.

OBJECTIVE: To assess changes in food pantries' consumer nutrition environment (CNE) after the provision of technical assistance. DESIGN: Pre-post study with 2 phases. SETTING: Staff completed observational assessments using the Nutrition Environment Food Pantry Assessment Tool (NEFPAT) at food pantries in an initial pilot phase. Then, staff conducted NEFPAT observations at pantries in Illinois statewide. PARTICIPANTS: In the pilot phase, 6 staff assessed 28 pantries. In the statewide phase, 35 staff assessed 119 pantries. INTERVENTION: After completing an initial NEFPAT at each pantry, technical assistance was provided by staff to support changes in the pantries' CNE before another NEFPAT observation was completed. MAIN OUTCOME MEASURE: Changes in the CNE, as assessed with the NEFPAT, when comparing preassessment and postassessment. ANALYSIS: Score differences were evaluated with paired t tests. RESULTS: In the pilot phase, among 23 pantries with preassessment and postassessment data, 2 objectives on the NEFPAT observation increased significantly. In the statewide phase, among 66 pantries with preassessment and postassessment data, most NEFPAT objectives and the overall NEFPAT score (22.12 ± 8.16 vs 28.20 ± 7.14, P < 0.001) significantly increased. CONCLUSIONS AND IMPLICATIONS: Technical assistance provided by Supplemental Nutrition Assistance Program Education implementing staff were related to improvements in the CNE of food pantries in Illinois. Future work should evaluate the association of these CNE changes with changes in behavior among pantry patrons.

The Efficacy and Cost-Effectiveness of Replacing Whole Apples with Sliced in the National School Lunch Program.

The National School Lunch Program (NSLP) serves 29.6 million lunches each day. Schools must offer ½ a cup of fruit for each lunch tray. Much of this fruit may be wasted, leaving the schools in a dilemma. The objectives of this study were to evaluate the consumption of whole vs. sliced apples and determine the cost-effectiveness of the intervention. Researchers weighed apple waste at baseline and three post-intervention time points in one rural Midwest school. The costs of the intervention were collected from the school. The cost-effectiveness analysis estimates how often apples need to be served to offset the costs of the slicing intervention. A total of (n = 313) elementary student students participated. Students consumed significantly more sliced as compared to whole apples in intervention months 3 (ß = 21.5, p < 0.001) and 4 (ß = 27.7, p < 0.001). The intervention cost was USD 299. The value of wasted apple decreased from USD 0.26 at baseline to USD 0.23 wasted at post-intervention. The school would need to serve 9403 apples during the school year (54 times) to cover the expenses of the intervention. In conclusion, serving sliced apples may be a cost-effective way to improve fruit consumption during school lunch.
