Background: The emergence of alternative methods of obtaining groceries since the COVID-19 pandemic has raised new concerns regarding food safety. In this study, we sought to evaluate these concerns by evaluating how the procurement method of ground beef impacts the microbial load in the beef, as this has not been thoroughly studied. Methods: Specifically, we compared beef samples obtained from in-store shopping, grocery delivery, and meal kit delivery services to determine if these new, more convenient methods of grocery shopping impact the total microbial load or Escherichia coli present in the beef. We homogenized a total of 65 beef samples and plated dilutions on trypticase soy agar, MacConkey agar, and CHROMagar. Results: We found that in-store samples had the highest microbial load with an average of 5.06 log CFU/g, while grocery delivery samples resulted in an average of 4.76 log CFU/g and meal kit samples had an average of 4.23 log CFU/g when plated on TSA. This represents a 6.7-fold change between in-store samples and meal kit samples. These differences were not statistically significant (p = 0.1, ANOVA). When plated on MacConkey agar, in-store samples had a bacterial count at 3.0 log CFU/g, while grocery delivery samples had 2.99 log CFU/g and meal kit delivered samples had 3.05 log CFU/g. Suspected E. coli O157 colonies were detected using CHROMagar plates, as these plates function to change the coloration of positive E. coli O157 colonies to pink. Suspected E. coli O157 colonies were observed in three in-store samples, two grocery delivery samples, and one meal kit sample. After confirmatory agglutination testing, one meal kit sample was confirmed as E. coli O157. Conclusions: While trends suggest possible lower microbial contamination in delivery methods versus in-store shopping procurement, no statistical significance between methods was found. These findings indicate no significant changes in microbial loads in delivered ground beef, and the high variance suggests that all procurement methods still pose some level of risk. Full article

The contribution of meal kits to the waste problem has become a significant concern, leading consumers to demand sustainable practices from meal-kit companies. This study proposes a framework to understand customer behavior toward sustainable meal-kit brands that promote practices such as recycling and waste reduction. This study applies warm glow theory to investigate how pure and impure altruism affect consumers’ perceptions of a meal-kit brand’s sustainability, perceived price fairness, and continuance intention. The findings confirmed that meal-kit brands’ sustainable practices significantly enhanced consumers’ perceptions of brand sustainability, which in turn influenced their perceived price fairness and continuance intention. Furthermore, warm glow and altruistic values were found to significantly moderate the relationship between consumers’ perceptions of brand sustainability and their continuance intention. However, no significant moderating effects were observed between consumers’ perceptions of brand sustainability and perceived price fairness. This study contributes to a deeper understanding of the psychological mechanisms underlying consumer attitudes and behaviors toward meal-kit brands’ sustainability efforts. Full article

The coronavirus disease 2019 pandemic brought significant changes to dining practices. Using meal kits, restaurant meal replacements (RMRs), and contactless dining became common, accelerating the trend toward personalized and convenient meals. Nevertheless, many people continue to prefer visiting crowded restaurants, willingly accepting the inconvenience associated with crowdedness. This paradoxical phenomenon suggests deeper social and cultural motivations beyond the basic function of eating. This study explores the social and psychological attributes of perceived crowdedness in restaurants—affiliation motivation, social proof, and human ambience—and examines their effects on customers’ emotions and behavioral intentions. A quantitative survey was conducted to assess customers’ emotional and behavioral responses to crowded dining environments, and the proposed relationships were tested using structural equation modeling. The results showed that all three attributes had a positive effect on emotional responses such as pleasure and arousal. However, only pleasure significantly influenced behavioral intentions, including revisit and word-of-mouth intentions, while arousal did not. These findings suggest that emotional pleasure derived from crowded dining environments is a key factor in encouraging continued customer engagement. The study offers theoretical and practical implications for designing emotionally and socially sustainable restaurant environments in the post-pandemic era. Full article

Vegetable intake among military Service Members (SMs) is well below public health guidelines, with only 12.9% meeting the Dietary Guidelines for Americans (DGAs). Low vegetable consumption negatively impacts diet quality as measured by the Healthy Eating Index (HEI), and poses risks to health and performance. Given the high physical and mental demands of military life, improving diet quality, including through increased vegetable intake, is crucial for optimizing health and readiness. Providing meal kits may help improve vegetable intake by reducing access-related barriers for SMs living or working on a military base. Furthermore, the addition of spices and herbs is a readily modifiable accompanying approach to address taste-related barriers and increase intake that has shown promise in other populations with poor diet quality. Background/Objectives: This study aimed to evaluate whether heat-and-serve meal kits with spices and herbs could increase vegetable intake and liking among active-duty SM by simultaneously targeting barriers to healthy eating and modifiable sensory factors. Methods: Conducted at Naval Support Activity Bethesda, the study randomly distributed heat-and-serve meal kits (n = 400) featuring either spiced (n = 200) or plain versions (n = 200) of four vegetables (broccoli, carrots, cauliflower, and kale). Each kit contained a quick response (QR) code for participants to upload post-consumption photos and rate vegetable liking on a nine-point Likert scale. Food photography (SmartIntake^®) was used to estimate vegetable consumption. Paired t-tests were used to determine differences between the intake of plain and spiced vegetables. Results: Intake of the heat-and-serve vegetables was very high for both the spiced and plain preparations (1.73 out of 2 cups, 87%). There was minimal difference (p = 0.87) between the consumption of spiced (1.75 cups) and plain (1.725 cups) vegetables, suggesting that both were well accepted. Overall, convenient and accessible meal options, alongside sensory-driven strategies, appear to improve some barriers to vegetable consumption in SM populations. Conclusions: Future studies should explore long-term outcomes and adaptability across different military environments, while considering additional factors, including convenience and time constraints, that influence dietary choices in the military.

The purpose of this study was to investigate the effects of dietary supplementation of myo-inositol (MI) on the blood metabolite profile in two high-performing laying hen strains. Diets were corn-soybean meal-based and not supplemented or supplemented with 1, 2, or 3 g MI/kg feed. Ten hens per strain (Lohmann Brown-classic (LB) and Lohmann LSL-classic (LSL)) and diet were euthanized at the age of 30 weeks following a 4-week feeding period in metabolic units. Plasma and liver samples were taken from each individual hen. The Absolute-IDQ^TM p180 kit (Biocrates, Innsbruck, Austria) was used for metabolite profiling in plasma, plasma insulin, and liver triglyceride content were determined by a chicken-specific ELISA and a spectrometric assay, respectively. Supply of dietary MI caused only minor changes in metabolite profiles despite increased plasma MI concentrations. These changes indicated weak anti-inflammatory and antioxidative effects of MI feeding in laying hens. The effect of strain on metabolite profiles was more pronounced, indicating a higher level of metabolic inflammation in LB hens. By K-means cluster analysis, two clusters (KMC1, KMC2) of hens were identified with enhanced serotonin concentrations in KMC2 hens irrespective of strain and feeding. Further research is needed to assess the biological role of these findings. Full article

A data-driven 3D simulation for the robotic automation of the most labor-intensive packaging process in meal kit production was developed using Tecnomatix plant simulation software. The workflow and environments of the existing manual process were analyzed. An existing production site was scanned using a 3D Lidar scanner to create 3D models and design the initial assembly layout. Two types of 3D simulation models, implemented with a single or double delta robot, were designed to determine the optimal robot-automated packaging process. Key performance indicators for simulation models of a manual and two robot automation systems were analyzed. The throughputs of the manual, single delta robot and double delta robot models were 2112, 1510, and 2568 ea/h, respectively. The single robot system achieved only 68.3% of the throughput of the manual process, which is attributed to a cycle time of 2.36 s for picking and placing all components. On the other hand, the cycle time of the double robot system was 1.66 times faster, and the throughput was 1.7 times greater compared to the single robot system. The developed 3D simulation model for the meal kit packaging system demonstrates the potential of robotic automation in addressing the labor shortage issue as well as improving production efficiency.

Producers and distributors of meal kits promote their products by emphasising customisation and a health-conscious approach to eating. Consumers of these services expect that, for an appropriate fee, they will receive a nutritious and flavourful meal, tailored to their individual needs and conveniently delivered to their homes. This raises the question of whether meal kit companies meet these expectations and whether their products are prepared with the level of care claimed in their advertisements. This scoping review aims to present available evidence that offers insight into the nutritional content, safety, and acceptability of meal kit delivery services. In this context, we have identified 15 publications. To the best of our knowledge, this is the first scoping review to focus specifically on meal kits. The findings highlight the significant potential of meal kits and may contribute to efforts to enhance their quality. Available research on meal kit delivery services was conducted using calculation methods. Nutritional value studies involving analytical methods and intervention studies are necessary in order to expand the understanding of the potential of meal kits role in whole-food nutrition.

Background/Objective: Students’ taste preferences, cooking skills, and cultural backgrounds impact their use of food access resources on campus. Meal kits include pre-sorted ingredients, which could address food waste and help to prepare meals with unfamiliar ingredients. The objective of this exploratory pilot study was to develop and investigate the impact of culturally relevant meal kits on cooking skills, food waste, and food security tailored to UC Davis students. Methods: Meal kits included ingredients found at the campus food pantry. Three culturally relevant recipes were selected: High-Protein Avocado Toast, Mexican-Inspired Quinoa Bowl, and a Korean Vegetable Stir-Fry. Students were randomly assigned to the intervention meal kit group (n = 50), while the comparison recipe card group received a digital recipe card (n = 25). Data were collected through pre- and post-surveys administered online, in addition to open-ended, qualitative feedback through surveys after each meal kit or recipe card. Results: Thirty-two participants in the meal kit group and four participants in the recipe card group completed all study measures. Both groups experienced an increase in being classified as high food security over the three-week intervention period (+13% in the intervention group and +75% in the comparison group). Further, the intervention group improved cooking self-efficacy (+1.2 points; p < 0.01) and food waste practices. Participants appreciated the meal kits’ ease of preparation, clear instructions, and minimal cooking steps. Conclusions: The preliminary findings of this exploratory pilot study highlight the potential importance of culturally relevant interventions to address food security and promote healthier eating habits among college students. However, more research is needed with a larger, more diverse sample over a longer duration. Full article

Food security continues to be an issue in the United States, especially in urban healthy food priority areas. Most interventions prioritize physical and economic access, just one of the four pillars of food security. We present the beginnings of a framework to help qualitatively assess an intervention’s contributions to various dimensions and sub-dimensions of food security and summarize the contributions of dominant interventions observed in the literature. We have followed Food Forward, a meal box social enterprise, since its conception in 2021. As a case study, we apply the framework and find that meal boxes have the potential to comprehensively address all dimensions of food security at the household level. Community involvement in strategic planning and operations can improve food utilization, and a financially sustainable social enterprise model can facilitate access, availability, and utilization stability. Future research is needed to develop the framework further by adding indicators to assess individual and collective contributions of community-based interventions to household food security. Longitudinal studies for innovative social business models for meal boxes are necessary to assess their contribution to the stability dimension of household food security. Full article

This study examines at the prevalence and spread of Hepatitis A Virus (HAV) and norovirus GI/GII in local and imported food products in Greece over a five-year period (2019–2024). A total of two hundred sixty-six food samples were evaluated using obligatory inspections and virus detection procedures, including 202 for Hepatitis A and 64 for Norovirus. High-risk categories analyzed were vegetables [138 (HAV), 17 (NoV)], fruits [16 (HAV), 7 (NoV)], soft fruits/berries [37 (HAV), 31 (NoV)], processed meals [4 (HAV), 4 (NoV)], and animal-based products [1 (HAV), 5 (NoV)]. Viral RNA was isolated using QIAamp Viral RNA Mini Kit and detected using established RT-qPCR procedures that met ISO requirements for high sensitivity and reproducibility. The results demonstrated HAV contamination mostly in vegetables (4.35% positive rate), with sporadic findings in other categories. Norovirus GI/GII was detected primarily in soft fruits/berries, with a category-specific positive rate of 6.45%. A temporal study revealed that HAV peaks in 2020, while Norovirus contaminations were detected in 2021 and 2024. The findings highlight the important need to incorporate viral testing into routine food safety procedures, especially for high-risk product categories. This study establishes a basic framework for public health initiatives that address gaps in foodborne virus surveillance in Greece. The study’s ramifications extend to global efforts to monitor and reduce foodborne virus contamination, pushing for higher regulatory requirements and targeted preventative actions. Full article

Ready-to-cook (RTC) foods can significantly improve the cooking experience of busy or unskillful consumers, based on production involving technical combinations of food processing and packaging. Initialized by a market survey of 172 products in Beijing, this systematic review analyzes RTC foods’ development status according to ingredients, packaging, and storage conditions to further clarify the scope of RTC foods. The working principles and efficacy of various food processing techniques, such as washing, cutting, marinating, and frying, and packaging design or innovations such as modified atmosphere packaging (MAP) were both summarized in detail, with attention to their ability to extend shelf life, reduce safety risks, and maximize production efficiency in RTC food production. The cutting-edge technologies that may potentially apply in the RTC food processing or packaging sector were compared with current approaches to visualize the direction of future developments. In conclusion, we have observed the specific pattern of RTC food varieties and packaging formats in the Beijing market and revealed the advancements in RTC food technologies that will continue playing a critical role in shaping this growing market, while challenges in scalability, cost-efficiency, and sustainability remain key areas for future research. The data and perspectives presented will articulate the conceptions and existing challenges of RTC food, foster consumer perception and recognition of similar products, and deliver useful guidance for stakeholders interested in such products.

The Dietary Guidelines for Americans (DGA) recommend twice-weekly consumption of seafood for health benefits, yet many U.S. consumers have historically fallen short of this target. The economic and societal impacts of the COVID-19 pandemic brought concern about further declines in seafood intake. This study evaluated the influence of COVID-19 on seafood intake among U.S. residents, toward understanding potential public health implications. A nationally representative cross-sectional survey of 1200 U.S. residents conducted in June 2021 evaluated the frequency and types of seafood consumed, and purchase methods used, before and during the early stages of the COVID-19 pandemic. The results (weighted data) indicate most U.S. consumers (90%) eat seafood, yet only 19% meet the seafood DGA. The likelihood of meeting the DGA was higher among consumers who were Asian, Black, or Hispanic; older; unmarried; of higher income; familiar with the DGA; choosing seafood for health reasons; and living in Atlantic or Gulf coast states. During COVID-19, some increased seafood intake for health reasons (45%), while others reduced intake due to factors such as cost (29%), limited availability (16%), and challenges with preparation (11%). Fresh salmon (68%), frozen shrimp (59%), and cooked oysters (41%) were most frequently purchased by consumers of these foods. More consumers indicated purchasing wild salmon (62%), shrimp (44%), and oysters (51%) than farm-raised products, though many were unsure. Fewer consumers included seafood in online grocery orders (36%) than meal kit orders (61%) when using these services. Though many consumers continued to eat seafood despite decreased restaurant patronage, most did not reach the intake level needed to maximize health benefits. Educational and marketing efforts promoting the health benefits of seafood and the convenience of procurement via online purchase methods may encourage intake across demographic groups to benefit public health outcomes in the U.S. Full article

Meal kits have become increasingly popular as a convenient solution for consumers seeking to prepare high-quality meals at home, falling under the ready-to-cook category. The rising number of subscriptions and the growing presence of companies offering meal kit services illustrate the popularity of this industry. The aims of this study include (a) identifying consumer perceptions of the health and sustainability aspects of meal kit services; (b) exploring how these perceptions influence consumer satisfaction; (c) examining the influence of consumer satisfaction on the intention to repurchase meal kits and recommend them to others; and (d) investigating potential significant differences among meal kit users with dietary, health, and environmental concerns. This exploration encompasses the effects of meal kits’ attributes on each group’s perceived value, satisfaction, and behavioral intentions. The partial least squares technique was utilized to test the research model using SmartPLS 4. Results of the current study support findings of past research suggesting that consumer perceptions of sustainability and healthiness positively influence their satisfaction and consequently their behavioral intentions. The findings of this study also offer practical implications for meal kit companies. Since consumer satisfaction is significantly influenced by both perceived healthiness and sustainability, companies should re-consider their branding strategies by focusing more on environmentally friendly advertising that makes connections between their attributes.

The role of diet in shaping oral microbiota and its potential contribution to the development of periodontal pathogens cannot be understated. This study aimed to explore the correlation between dietary habits and the prevalence of 11 periodontal pathogens among children and adolescents in Oradea, Romania. The identification of these pathogens was performed using the micro-IDent test kit, capable of detecting 11 specific periodontal pathogens. Bacterial sampling was conducted from the crevicular fluid in the morning, prior to brushing, followed by the completion of a brief questionnaire by parents. The questionnaire captured various aspects of the children’s eating habits, including meal frequency, consumption of sweets, and hydration levels. The collected samples were dispatched to the laboratory for analysis, which provided insights into the abundance of microorganisms. The study encompassed 60 participants aged between 2 and 18 years, with the majority reported by their parents to have regulated meal timings, frequent sugar intake, and adequate hydration. The findings revealed significant associations between certain dietary factors and the presence of specific periodontal pathogens. Notably, the absence of breastfeeding was linked with the detection of Tannerella forsythia and Campylobacter rectus. Furthermore, frequent consumption of sweets corresponded with the presence of Capnocytophaga spp., which was particularly observed in individuals consuming sweets 2–3 times a day. Insufficient age-appropriate hydration showed an association with the prevalence of T. forsythia, Peptostreptococcus micros, and Capnocytophaga spp. In this sample, it became evident that eating habits and diet influenced the presence of several periodontal pathogens. The lack of breastfeeding was predominantly associated with positive results for T. forsythia and C. rectus, while inadequate hydration correlated more frequently with the presence of T. forsythia and P. micros. Moreover, frequent consumption of sweets was linked to the presence of Capnocytophaga spp. Full article

The Dietary Approaches to Stop Hypertension (DASH) eating plan is the most effective dietary intervention for cardiovascular disease (CVD), but it excludes the consideration of culture and cost. The Hispanic/Latine population is disproportionately affected by CVD, with risks increasing if persons are accustomed to a Westernized diet. This research aims to understand the cultural dietary practices aligned with a DASH eating plan and the social determinants of health impacting fruit and vegetable (F/V) consumption among immigrant Hispanic/Latine individuals at a community-based clinic in Minnesota. Utilizing community-based participatory research methods, a community survey informed the development of DASH-focused, medically tailored food kits of varying F/V modalities. Qualitative feedback was sought out regarding the kits when presented to 15 individuals during in-depth interview sessions to validate the cultural appropriateness of food kits for clinical use. Box A was the highest rated kit (66.7%) and consisted of fresh F/V. The average F/V consumption per day was 2.6 ± 1.4 servings. The food insecurity questionnaires showed high/marginal (40%), low (53.3%), and very low (6.7%) food security. The barriers to consuming F/V were money, time, and transportation. Understanding cultural dietary practices related to the DASH eating plan is necessary to mitigate CVD risk and provide inclusive medical nutrition therapy for Hispanic/Latine populations. Full article
