Seafood processing byproducts (SB) such as bones and skin can be safely used as food ingredients to increase profitability for the seafood sector and provide nutritional value. An online survey of 716 US adult seafood consumers was conducted to explore SB trial intent, responsiveness to health and safety information, and associated elicited emotions (nine-point Likert scale). Consumers’ SB-elicited emotions were defined as those changing in reported intensity (from a baseline condition) after the delivery of SB-related information (dependent t-tests). As criteria for practical significance, a raw mean difference of >0.2 units was used, and Cohen’s d values were used to classify effect sizes as small, medium, or large. Differences in willingness-to-try, responsiveness to safety and health information, and SB-elicited emotions were found based on self-reported gender and race, with males and Hispanics expressing more openness to SB consumption. SB-elicited emotions were then used to model consumers’ willingness-to-try foods containing SB via logistic regression modeling. Traditional stepwise variable selection was compared to variable selection using raw mean difference > 0.2 units and Cohen’s d > 0.50 constraints for SB-elicited emotions. Resulting models indicated that extrinsic information considered at the point of decision-making determined which emotions were relevant to the response. These new approaches yielded models with increased Akaike Information Criterion (AIC) values (lower values indicate better model fit) but could provide simpler and more practically meaningful models for understanding which emotions drive consumption decisions.

Background: The Lingnan region is characterized by a hot and humid climate and abundant, diverse natural resources, while the Central Plains region experiences distinct four seasons and has a rich agricultural culture. Both regions possess unique dietary traditions and preferences. This study aims to investigate the differences in dietary structure between the Lingnan region (Guangdong, Guangxi, Hainan) and the Central Plains region (Shanxi, Shaanxi, Henan) and their impact on health. Methods: Using cross-sectional survey data from the 2015–2017 China National Nutrition and Health Survey, this study selected residents aged 18 and above as the research subjects. Generalized linear models were employed to analyze differences in the intake of various food groups between the two regions, while logistic regression models were used to examine regional differences in the prevalence of obesity, hypertension, diabetes mellitus, and hyperlipidemia. Results: A total of 14,484 adults were included in this study. Lingnan participants consumed significantly more rice products, red meat, poultry, seafood, and dark-colored vegetables, while Central Plains residents had higher intakes of wheat products, other cereals, soybeans, and eggs. Lingnan exhibited lower prevalence rates of obesity (8.6% vs. 18.1%), diabetes (7.6% vs. 9.8%), and hypertension (33.0% vs. 46.9%) compared to the Central Plains, with no significant difference in hyperlipidemia prevalence. Adjusted analyses confirmed that Lingnan residents had significantly reduced risks of obesity (OR = 0.431, 95% CI: 0.388–0.479), diabetes mellitus (OR = 0.841, 95% CI: 0.744–0.950), and hypertension (OR = 0.564, 95% CI: 0.523–0.608). Conclusions: The dietary structure in the Lingnan region plays a positive role in cardiometabolic health. Further analysis of the combined effects of different foods on health could provide a scientific basis for future nutrition and health management. Full article

The diagnosis of allergic reactions to Anisakis remains challenging due to the lack of specific allergens available for routine clinical use. However, the latest version of the multiplex macroarray ALEX-2 now allows the detection of specific IgE against Ani s 1, the major species-specific allergen, as well as Ani s 3 (tropomyosin), a highly cross-reactive molecule with homologs in other allergenic sources. This study aimed to evaluate the potential role of ALEX-2 in diagnosing Anisakis sensitization by comparing it with a previously validated diagnostic algorithm. Serum samples from patients with suspected Anisakis sensitization were consecutively collected at an Italian allergy centre. Diagnosis was based on a history of allergic reactions following seafood consumption, along with negative test results for fish allergy. All patients underwent skin prick testing and specific IgE measurement for Anisakis (p4), Ascaris (p1), shrimp (f24), and Dermatophagoides pteronyssinus (d1), as well as tropomyosins from house dust mites (d205) and shrimp (f351). Additionally, the basophil activation test (BAT) using crude Anisakis extract was performed. Patients were also tested using the ALEX-2 allergy macroarray. Correlation analyses and multiple logistic regression models were applied to assess associations between conventional singleplex tests and the severity of clinical manifestations. A total of 33 eligible subjects were recruited, including 20 females (60.6%). Seven (21.2%) were aged 0–29 years, eleven (33.3%) were 30–60 years old, and fifteen (45.5%) were over 60 years old. ALEX-2 showed positivity for Ani s 1 or Ani s 3 in 39.39% (95% CI: 22.90–57.86%) of subjects with confirmed Anisakis sensitization. A significant correlation was observed between Ani s 3 (r = 0.31 [95% CI: 0.04–0.56], p = 0.01) and Ascaris (r = 0.35 [95% CI: 0.129–0.55], p = 0.004) levels and the severity of clinical reactions. Despite the limitations of this cross-sectional study, including a small sample size, our preliminary findings suggest that the ALEX-2 macroarray may not be sufficiently sensitive for the first-line diagnosis of Anisakis allergy. However, it could provide valuable additional information, as Ani s 1 positivity indicates primary sensitization to the nematode, while Ani s 3 positivity appears to correlate with clinical severity. Larger prospective longitudinal studies are needed to confirm these findings and further assess the predictive value of ALEX-2 in diagnosing Anisakis allergy. Full article

Background: The rise of asthma prevalence in recent decades has been attributed to changes in dietary patterns, especially in developing countries. Studies have also suggested that dietary patterns play an important role in both asthma development and management. This study aimed to investigate the association between consumption of various foods and environmental factors with asthma and wheeze among adolescents. Methods: A self-administered standardized International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was used to collect data on demographics, respiratory health, exposure to air pollution, and diet on n = 2855 adolescents residing in Vhembe District, South Africa. Results: The prevalence of asthma and wheeze were 18.91% and 37.69%, respectively. Consuming various foods such as fast foods (OR = 1.41; 95% CI: 1.06–1.88), bread (OR = 0.60; 95% CI: 0.45–1.81), pasta (OR = 1.39; 95% CI: 1.06–1.84), seafood (OR = 1.79; 95% CI: 0.65–1.24), and nuts (OR = 0.85; 95% CI: 0.65–1.12) were significantly associated with asthma in the crude logistic regression analysis. Further analysis in the multiple regression model indicated a strong association of asthma with consumption of nuts (OR = 1.55; 95% CI: 1.11–2.17), seafood (OR = 1.60; 95% CI: 1.03–2.49), and cereal (OR = 0.67; 95% CI: 0.45–0.99). In relation to wheeze, consumption of meat (red) (OR = 0.77; 95% CI: 0.60–0.99) was a protective factor in the crude analysis. The multiple logistic regression model showed that, seafood (OR = 0.76; 95% CI: 0.59–0.96), fruit (OR = 0.55; 95% CI: 0.32–0.94), nuts (OR = 1.88; 95% CI: 1.50–2.66), and olive oil (OR = 1.48; 95% CI: 1.09–2.00) were significantly associated with wheeze. Conclusion: Diet plays a major role in respiratory health, especially in asthma and wheeze. Dietary changes may play a role in reducing the burden of asthma and other respiratory symptoms in adolescents. Full article

Cold chain logistics possesses unique characteristics, particularly the necessity to maintain low temperatures within containers throughout the distribution process. Real-world traffic conditions, such as congestion, significantly impact the efficiency of cold chain logistics and contribute to increased carbon emissions. To foster green and sustainable development in this sector, a carbon emission trading mechanism has been established, incentivizing companies to invest in energy conservation and emission reduction through economic transactions. This study introduces a multi-objective optimization model for route planning in port seafood logistics, integrating considerations of traffic congestion and zero-carbon transportation. To accurately reflect real-world traffic conditions, a time-dependent function is utilized to model traffic congestion within actual road networks. The road segments are divided, and the travel time for vehicles in each segment is computed. Additionally, the costs associated with the distribution process are analyzed, leading to the development of a multi-objective optimization model aimed at minimizing both distribution costs and zero-carbon transportation costs. The proposed model demonstrates significant economic savings and environmental advantages, providing a theoretical foundation for decision-making processes that support the green and sustainable development of port seafood logistics.

Considering the growing consumer demand for local food products in the United States, several restaurants are seeking to include locally sourced meat and seafood products on their menus. Despite this trend, limited research has examined what factors encourage or discourage restaurants from purchasing or purchasing more local proteins. This study extends the literature by investigating what traits are desired and what barriers exist when purchasing local proteins for restaurant procurers (those tasked with purchasing ingredients), utilizing data from an online survey. The results indicate that the top three desired traits for locally raised meats (beef, pork, chicken) are naturally grown, hormone-free, and organic. The most important traits for seafood (fish, crab, shrimp, and oysters) are the different certifications (i.e., Marine Stewardship Council, state/local certification, and Aquaculture Stewardship Council). The most common barriers are inconsistent quality, high cost, limited availability, and further processing needs. Results from a logistic regression suggest that restaurants characterized by fewer seats, higher entrée prices, and longer tenure are more likely to purchase local proteins. Restaurants willing to pay more for local proteins tend to be full-service types, have fewer seats, have higher entrée prices, serve other local foods, and cater to both tourists and residents.

Objective: This pilot cross-sectional study explored differences in dietary intake and eating behaviors between healthy adults and a group of adults taking insulin to manage diabetes. Methods: A characteristic questionnaire and up to four Automated Self-Administered 24-Hour dietary recalls were collected from 152 adults aged 18–65 years (96 healthy and 56 adults taking insulin) from Indiana and across the U.S. from 2022 to 2023. The macronutrient intake, diet quality via the Healthy Eating Index (HEI)-2015, eating frequency, and consistency of timing of eating were calculated and compared between the two groups using adjusted linear or logistic regression models. Results: The total mean HEI scores were very low, at 56 out of 100 and 49 out of 100 for the healthy and insulin-taking groups, respectively. Insulin-taking adults had significantly lower HEI total (p = 0.003) and component scores compared to the healthy group for greens and beans (2.0 vs. 3.0, p = 0.02), whole fruit (2.1 vs. 2.9, p = 0.05), seafood and plant proteins (2.1 vs. 3.3, p = 0.004), and saturated fats (3.7 vs. 5.4, p = 0.05). Eating frequency was significantly lower in the insulin-taking group than in the healthy group (3.0 vs. 3.4 eating occasions/day, p = 0.05). Conclusion: Evidence of the low diet quality and eating frequency of insulin takers may help inform and justify nutrition education to control and manage diabetes. Full article

Dietary changes expose consumers to risks from Anisakis larvae in seafood, leading to parasitic diseases and allergies. Anisakis is recognized by EFSA as a significant hazard, with potential oncogenic implications. Diagnostic advancements, like the Basophil Activation Test (BAT), enhance sensitivity and accuracy in identifying Anisakis sensitization, complementing traditional IgE tests. We conducted a cross-sectional study on patients with allergic symptoms from April 2021 to April 2023 at two outpatient clinics in western Sicily. Our goal was to assess the prevalence of Anisakis-related allergies and to identify risk profiles using specific Anisakis IgE and the BAT, especially in regions with high raw fish consumption. The study evaluated specific Anisakis IgE as a screening tool for Anisakis sensitization, using questionnaires, blood samples, and immuno-allergology analyses. Anisakis-specific IgE values were compared with the BAT results, with statistical analyses including Fisher’s exact test and logistic regression. The results showed an 18.5% seroprevalence of Anisakis IgE, while the BAT as a second-level test showed 4.63%, indicating the BAT’s superior specificity and accuracy. The study highlighted the importance of the BAT in diagnosing Anisakis sensitization, especially in cases of cross-reactivity with Ascaris and tropomyosin. The findings confirm the BAT’s exceptional specificity in identifying Anisakis sensitization and support using Anisakis-specific IgE for population-based risk profiling. The BAT can effectively serve as a confirmatory test. Full article

The development of cold chain logistics for seafood plays a pivotal role in guaranteeing food safety, promoting economic progress, reducing losses, and fostering sustainable development, thereby enhancing the overall efficiency of the seafood supply chain. This study conducted a comprehensive investigation into the primary research focuses of the seafood cold chain logistics field using the literature on visualization analysis software (CiteSpace (6.2.R6), VOSviewer (1.6.20), and RStudio Bibliometrix (4.4.0)). A total of 1787 articles were collected and further analyzed from the China National Knowledge Infrastructure (CNKI), Web of Science (WOS), and Google databases over 12 years, establishing a knowledge framework for research in seafood cold chain logistics. Through the utilization of keyword clustering and emerging analysis techniques, the study constructed a knowledge map that intuitively describes the emerging trends and key hotspot in this field. The results indicate a growing trend in the seafood cold chain logistics field, with disciplines such as mathematics, systems, and physics being notably prominent. Key terms such as “cold chain logistics”, “highlighted supply chain management”, “frozen storage techniques”, “cold storage practices”, “post-harvest loss prevention strategies”, and “optimization of the cold chain” frequently appear in the literature, highlighting the importance of interdisciplinary academic research in these areas. By exploring the current development of the seafood cold chain logistics field, we strengthen the research gaps in the literature and propose future research directions. Therefore, well-conducted bibliometric studies can play a crucial role in advancing the field by providing comprehensive insights, facilitating scholarly discussions, identifying knowledge gaps, generating new research ideas, and showcasing their intended contributions to the field.

Background and objectives: Mindful eating (ME) is defined as non-judgmental awareness of the physical and emotional sensations experienced while eating. An association between ME and healthier eating behaviors has been suggested. However, there are only few observational studies available. The aim of this cross-sectional study was to investigate the association between ME levels and food consumption, in particular, diet quality, food groups, and ultra-processed food consumption, in a general population sample. Methods: In 2022, 2069 participants of the NutriNet-Santé Study completed the Mind-Eat scale, a validated questionnaire assessing ME as a whole and its six dimensions. Participants also completed at least three 24 h dietary records. Adherence to the French dietary guidelines was assessed via the French National Nutrition and Health Program Guideline Score (PNNS-GS2). The degree of food processing was assessed using the NOVA classification. Logistic and linear regressions were used to analyze associations between ME as the exposure (score from 1 to 5), and diet quality, food groups, and ultra-processed food consumption as outcomes, stratified by sex, and considering sociodemographic and lifestyle covariates. Results: Men and women with a higher ME score showed better adherence to dietary guidelines (men: β = 1.05, 95%CI: 0.53, 1.58; women: β = 0.74, 95%CI: 0.40, 1.09), and a lower consumption of ultra-processed food (men: β = −0.02, 95%CI: −0.04, −0.01; women: β = −0.02, 95%CI: −0.03, −0.01). They also consumed fewer dairy products and meat, and more non-salted oleaginous foods. In addition, women with higher levels of ME consumed more fats and eggs, and fewer processed meat and chocolate based-products, while men consumed more vegetables, whole-grain products, and starches, and less seafood. Regarding macronutrients, individuals with higher levels of ME consumed less protein overall and animal protein, but more plant-based protein. In addition, women with higher ME levels consumed more added fats and omega 3, and less total energy and simple and added carbohydrates, while men consumed more fibers and plant-based lipids. Discussion: ME was associated with a healthier overall diet. These findings suggest that ME could be helpful in the promotion of healthy eating behaviors. Further studies on the dimensions of ME are needed. Full article

(1) Background: Although studies have suggested that dietary interventions may have potential benefits over conventional medical treatments, research on the association between dietary patterns and hyperemesis gravidarum (HG) in pregnant women is scarce. (2) Methods: To explore the relationship between dietary patterns and the risk of HG, a cross-sectional study was conducted in Xi’an, China from April 2021 to September 2022. Dietary intake was assessed by a semi-quantitative food-frequency questionnaire, and then factor analysis was used to derive dietary patterns. HG was defined as persistent and severe nausea and vomiting with weight loss ≥ 5%, pregnancy-unique quantification of emesis (PUQE) score ≥ 13, or hospitalization due to vomiting. Logistic regression models were used to estimate ORs and 95% CIs for HG according to dietary pattern scores. Stratified analyses and tests for interaction were performed by potential confounders. (3) Results: Of the 3122 pregnant women enrolled, 2515 individuals (mean age: 31.2 ± 3.4 years) were included in the final analysis. In total, 226 (8.9%) pregnant women were identified as having HG. Five dietary patterns were identified. After adjusting for covariates, the highest quartile of the “fish, shrimp and meat” and “egg, milk and water drinking” patterns was associated with a 37% and 58% lower risk of HG compared with the lowest quartile, respectively (p-trend < 0.05). Conversely, the highest quartile of the “beverage” pattern was associated with a 64% higher risk of HG compared with the lowest quartile (p-trend = 0.02). Furthermore, significant interactions were observed between the “egg, milk and water drinking” pattern and parity, employment status and nutritional supplement use (p-interaction < 0.05). (4) Conclusions: A diet rich in eggs, milk, seafood and unprocessed poultry and animal meat may be a protective factor against HG, while a diet high in beverages may be detrimental to HG. These associations may vary by parity, employment status and nutritional supplement use. Full article

Hyperuricemia (HUA) is associated with a wide range of diseases and increases the public health burden on society as a whole. In addition to genetic variation, diet plays a crucial role in the prevention and treatment of HUA as an important modifiable behavior. The purpose of this study is to investigate whether food groups and consumption time are associated with HUA. A total of 41,230 participants from the National Health and Nutrition Examination Survey between 2005 and 2018 were included in the study. All meals, including breakfast, lunch, and dinner, were obtained according to their corresponding Food Patterns Equivalents Database dietary data. The binary logistic regression model was used to analyze the relationship between food groups, food consumption time and HUA. We found that the intake of fruit (mixed in various forms) (OR = 0.942, 95% CI: 0.909–0.976) or freshly squeezed juices (OR = 0.915, 95% CI: 0.859–0.975), milk (OR = 0.839, 95% CI: 0.808–0.872), and eggs (OR = 0.881, 95% CI: 0.839–0.924), poultry (OR = 1.055, 95% CI: 1.033–1.077) and seafood high in n-3 fatty acids (OR = 1.068, 95% CI: 0.1.018–1.120) at dinner, eating refined grains at breakfast (OR = 0.954, 95% CI: 0.924–0.985) and dinner (OR = 0.962, 95% CI: 0.944–0.980), eating whole grains (OR = 0.908, 95% CI: 0.845–0.976) at lunch, consuming alcoholic beverages or foods at breakfast (OR = 0.748, 95% CI: 0.564–0.990)/lunch (OR = 1.118, 95% CI: 1.008–1.240)/dinner (OR = 1.127, 95% CI: 1.073–1.185) were associated with HUA. Eating particular meals at particular times of the day was related to a lower risk of HUA. Full article

With increasing global demand for seafood, seafood byproducts (SB) utilization can contribute to a more sustainable food supply chain through waste-to-value food product development. However, consumer perceptions of SB (e.g., fish skin and bones) are underexplored. Therefore, this study aims to evaluate some factors influencing consumers’ willingness-to-try seafood byproducts. An online survey was conducted in the USA regarding intervention of SB informational cues with N = 904 adult seafood consumers internationally. The proportion of consumers willing to try SB increased significantly (McNemar’s test, α = 0.05) from 47% to 68% after SB safety and health claims had been presented in the questionnaire. Gender, race, SB knowledge, and previous SB consumption were significant predictors of trial intent (based on logistic regression), as were emotional baseline scores during the COVID-19 pandemic. Males were more open to SB consumption than females, and racial identity was associated with differential responsiveness to SB information. Higher levels of “bored” and “unsafe” feelings, and lower levels of “free” were associated with increased SB trial intent. Potential SB consumers identified fish products (82% willingness-to-try); seasoning mix, sauces, and dressing (71% willingness-to-try); and soup and gravy products (62% willingness-to-try) as most appropriate for SB incorporation. Predominant reasons for SB avoidance were concerns about sensory quality, safety, and nutrition. These consumer-driven data could guide SB product development concepts to encourage trial and overcome aversions through new consumption experience. Full article

The control of the pathogenic load on foodstuffs is a key element in food safety. Particularly, seafood such as cold-smoked salmon is threatened by pathogens such as Salmonella sp. or Listeria monocytogenes. Despite strict existing hygiene procedures, the production industry constantly demands novel, reliable methods for microbial decontamination. Against that background, a microwave plasma-based decontamination technique via plasma-processed air (PPA) is presented. Thereby, the samples undergo two treatment steps, a pre-treatment step where PPA is produced when compressed air flows over a plasma torch, and a post-treatment step where the PPA acts on the samples. This publication embraces experiments that compare the total viable count (tvc) of bacteria found on PPA-treated raw (rs) and cold-smoked salmon (css) samples and their references. The tvc over the storage time is evaluated using a logistic growth model that reveals a PPA sensitivity for raw salmon (rs). A shelf-life prolongation of two days is determined. When cold-smoked salmon (css) is PPA-treated, the treatment reveals no further impact. When PPA-treated raw salmon (rs) is compared with PPA-untreated cold-smoked salmon (css), the PPA treatment appears as reliable as the cold-smoking process and retards the growth of cultivable bacteria in the same manner. The experiments are flanked by quality measurements such as color and texture measurements before and after the PPA treatment. Salmon samples, which undergo an overtreatment, solely show light changes such as a whitish surface flocculation. A relatively mild treatment as applied in the storage experiments has no further detected impact on the fish matrix. Full article

The aim of this study was to examine the association between dietary patterns and high blood glucose in Jiangsu province of China by using structural equation modelling (SEqM). Methods: Participants in this cross-sectional study were recruited through the 2015 Chinese Adult Chronic Disease and Nutrition Surveillance Program in Jiangsu province using a multistage stratified cluster random sampling method. Dietary patterns were defined by exploratory factor analysis (EFA). Confirmatory factor analysis (CFA) was used to test the fitness of EFA. SEqM was used to investigate the association between dietary patterns and high blood glucose. Results: After exclusion, 3137 participants with complete information were analysed for this study. The prevalence of high blood glucose was 9.3% and 8.1% in males and females, respectively. Two dietary patterns: the modern dietary pattern (i.e., high in red meats and its products, vegetables, seafood, condiments, fungi and algae, main grains and poultry; low in other grains, tubers and preserves), and the fruit–milk dietary pattern (i.e., high in milk and its products, fruits, eggs, nuts and seeds and pastry snacks, but low in vegetable oils) were established. Modern dietary pattern was found to be positively associated with high blood glucose in adults in Jiangsu province (multivariate logistic regression: OR = 1.561, 95% CI: 1.025~2.379; SEqM: β = 0.127, p < 0.05). Conclusion: The modern dietary pattern—high intake of red meats—was significantly associated with high blood glucose among adults in Jiangsu province of China, while the fruit–milk dietary pattern was not significantly associated with high blood glucose.
