Changing food choices: the option for high-protein foods and the move away from the Mediterranean diet.

PURPOSE:  The growing importance placed on health and physical well-being by consumers continues to influence food industry choices. The food market therefore, pandering to the desires for a lean and athletic body, offers new products deemed more healthy and able to impact body image. It is evidenced, thus, a change in food choices and habits, with more attention to the quality and nutrient content of the products consumed, in which protein is assuming increasing importance. The purpose of the study is to highlight important changes in eating habits and in particular the increase in the consumption of high-protein foods, attributable to the focus on physical fitness and thinness, resulting in a decreasing adherence to the Mediterranean diet and the progressive loss of its positive impact on health. METHODS AND RESULTS: This analysis is based on CIRCANA srl data on food consumption trends (change percentage of quantity and value sales) in recent years. Specifically, between January and September 2022 vs. 2021, there was a 21.6% increase in the sale of high-protein products, significantly higher than all the previous ones. CONCLUSIONS: The past few years have seen the gradual discovery of new products, at first little-known and niche, which are becoming major players on the national food consumption scene. The trend is toward a growing preference for high-protein foods and diets with the gradual abandonment of the Mediterranean and an increased risk of nutritional deficiencies, obesity, and cardiovascular disease. LEVEL OF EVIDENCE: Level IV, evidence obtained from multiple time series with or without the intervention.

Iron-rich food consumption and predictors among children aged 6-59 months old in Ethiopia: A multilevel complex sample analysis of the Ethiopian mini-demographic and health survey 2019 data.

BACKGROUND: Children with inadequate iron consumption had slower growth, weaker immunity, and poor cognitive development. Although the public health importance of iron-rich consumption in Ethiopia is known, evidence for iron-rich food consumption and predictors among children aged 6-59 months old in Ethiopia is sparse. This study aimed to assess iron-rich food consumption and predictors among children aged 6-59 months old in Ethiopia. METHODS: This study used Ethiopia mini demographic and health survey 2019 (EMDHS-2019) data with a total weighted sample size of 5,112 among children aged 6-59 months old. A multilevel mixed effect logistic regression analysis was used to identify predictors of good iron-rich food consumption. RESULTS: The proportion of good consumption of iron-rich foods among children aged 6-59 months was 27.99% (24.22, 32.10%). The findings revealed that children born to mothers who completed primary education [AOR = 1.88, 95% CI: 1.11, 3.19], a higher education [AOR = 4.45, 95% CI: 1.28, 15.48], being born to the poorer family [AOR = 1.89, 95% CI: 1.04, 3.43], richer [AOR = 2.12, 95% CI: 1.03, 4.36], and richest [AOR = 3.57, 95% CI: 1.29, 9.93] were positively associated with good iron-rich food consumption among children aged 6-59 months old. Nevertheless, being 24-59 month-old children [AOR = 0.58, 95% CI: 0.44, 0.72], residents of the Afar [AOR = 0.23, 95% CI: 0.08, 0.67], Amhara region [AOR = 0.30, 95% CI: 0.14, 0.65], and Somali region [AOR = 0.01, 95% CI: 0.01, 0.07] were negatively associated with good iron-rich food consumption among children aged 6-59 months old. CONCLUSION: The finding revealed that there was low consumption of iron-rich foods among children aged 6-59 months in Ethiopia compared to reports from East African countries. Improving women's literacy and economic empowerment would improve iron-rich food consumption among children aged 6-59 months old. This study's findings would have implications for policymakers in Ethiopia to enhance iron-rich food consumption.

Effect of Silencing subolesin and enolase impairs gene expression, engorgement and reproduction in Haemaphysalis longicornis (Acari: Ixodidae) ticks.

IMPORTANCE: Haemaphysalis longicornis is an obligate blood-sucking ectoparasite that has gained attention due its role of transmitting medically and veterinary significant pathogens and it is the most common tick species in Republic of Korea. The preferred strategy for controlling ticks is a multi-antigenic vaccination. Testing the efficiency of a combination antigen is a promising method for creating a tick vaccine. OBJECTIVE: The aim of the current research was to analyze the role of subolesin and enolase in feeding and reproduction of H. longicornis by gene silencing. METHODS: In this study, we used RNA interference to silence salivary enolase and subolesin in H. longicornis. Unfed female ticks injected with double-stranded RNA targeting subolesin and enolase were attached and fed normally on the rabbit's ear. Real-time polymerase chain reaction was used to confirm the extent of knockdown. RESULTS: Ticks in the subolesin or enolase dsRNA groups showed knockdown rates of 80% and 60% respectively. Ticks in the combination dsRNA (subolesin and enolase) group showed an 80% knockdown. Knockdown of subolesin and enolase resulted in significant depletion in feeding, blood engorgement weight, attachment rate, and egg laying. Silencing of both resulted in a significant (p < 0.05) reduction in tick engorgement, egg laying, egg hatching (15%), and reproduction. CONCLUSIONS AND RELEVANCE: Our results suggest that subolesin and enolase are an exciting target for future tick control strategies.

Spatiotemporal organization of ant foraging from a complex systems perspective.

We use complex systems science to explore the emergent behavioral patterns that typify eusocial species, using collective ant foraging as a paradigmatic example. Our particular aim is to provide a methodology to quantify how the collective orchestration of foraging provides functional advantages to ant colonies. For this, we combine (i) a purpose-built experimental arena replicating ant foraging across realistic spatial and temporal scales, and (ii) a set of analytical tools, grounded in information theory and spin-glass approaches, to explore the resulting data. This combined approach yields computational replicas of the colonies; these are high-dimensional models that store the experimental foraging patterns through a training process, and are then able to generate statistically similar patterns, in an analogous way to machine learning tools. These in silico models are then used to explore the colony performance under different resource availability scenarios. Our findings highlight how replicas of the colonies trained under constant and predictable experimental food conditions exhibit heightened foraging efficiencies, manifested in reduced times for food discovery and gathering, and accelerated transmission of information under similar conditions. However, these same replicas demonstrate a lack of resilience when faced with new foraging conditions. Conversely, replicas of colonies trained under fluctuating and uncertain food conditions reveal lower efficiencies at specific environments but increased resilience to shifts in food location.

Body image, eating distress and emotional-behavioral difficulties among adolescents in Mbarara, Southwestern Uganda.

BACKGROUND: Adolescents frequently have emotional and behavioral difficulties as they struggle with the challenges of transition from childhood to adulthood. Many struggle with issues of body image and eating distress as they deal with the difficult and frequently perplexing changes that occur with puberty. Yet there is surprisingly little research on the emotional and behavioral challenges, as well as body image and eating distress among this sizable population in Uganda. This study sought to assess attitudes and behaviors related to body image and eating distress, as well as emotional and behavioral difficulties among adolescents in Mbarara, Southwestern Uganda. METHODS: This was a cross-sectional study among 788 adolescents aged 13 to 19 years in secondary schools in Mbarara city and Mbarara district in south-western Uganda. The study employed the Body Image and Eating Distress scale to assess attitudes and behaviors about dieting and body shape and the extended version of the Strengths and Difficulties Questionnaire (SDQ) to assess for perceived emotional and behavioral difficulties. Logistic regression was used to identify the association between body image and eating distress and perceived difficulties. RESULTS: The prevalence of high body image and eating distress was 10.8% while that of perceived emotional and behavioral difficulties was 45.8%. Some of the adolescents (16.1%) were dissatisfied with their body shape, 24.6% exercised a lot to avoid gaining weight, 15.0% were terrified to gain even a little weight, and 12.1% could not control their eating. More males reported eating large amounts of food at one time (p = < 0.001). Having emotional and behavioral difficulties (aOR: 1.89; 95% CI: 1.18 - 3.02; p = 0.019) and coming from a two-parent household (aOR: 1.79; 95% CI: 1.10 - 2.92; p = 0.019) increased the odds of high body image and eating distress. CONCLUSION: High levels of body image and eating distress are linked to behavioral and emotional problems and adolescent's family structure. Clinicians who treat adolescents should use a holistic care strategy and be aware of the high prevalence and close association between emotional and behavioral difficulties, concerns about weight, and dieting. It is important to encourage parental involvement and support in providing information about mental health issues among adolescents.

Association between watching eating shows and unhealthy food consumption in Korean adolescents.

BACKGROUND: Eating habits formed during adolescence greatly influence the maintenance of health in adulthood. With the recent development of social media and easy access to the Internet, adolescents watch plenty of food videos, particularly Mukbang and Cookbnag(eating show)content. This media genre's impact on food choices has been covered in several studies; however, studies on unhealthy eating habits directly related to adolescents' exposure to eating shows are insufficient. METHODS: For this study, we used data from the 18th Korea Youth Risk Behavior Survey conducted in 2022 and finalized 50,451 participants. The extent of exposure to eating show media over the course of a week, as well as the consumption of fast food, sugar-sweetened beverages (SSBs), and high caffeinated beverages within that week were measured through self-reporting questionnaires. We classified the participants into two groups based on their frequency of watching eating shows. A multiple logistic regression analysis was performed to investigate the association between eating show and unhealthy food consumption. RESULTS: For both males and females, eating show exposure was strongly associated with the consumption of fast food (male: OR:1.37, 95% CI:1.26-1.49; female: OR:1.46, 95% CI:1.36-1.57), SSB (male: OR:1.42, 95% CI:1.26-1.60; female: OR:1.51, 95% CI:1.35-1.70), and high caffeinated beverage (male: OR:1.30, 95% CI:1.23-1.37; female: OR:1.24, 95% CI:1.18-1.31). It was observed that both sexes were more likely to frequently eat unhealthy food than students who did not watch eating shows. CONCLUSION: Among Korean adolescents, students exposed to eating shows, which primarily aim to entertain, were more likely to consume fast food, SSBs, and high caffeinated beverages. Therefore, this study's findings suggest that eating show could influence adolescents' food choices, highlighting the need for interest in emerging cultures and corresponding health policies.

Development of eating skills in infants and toddlers from a neuropediatric perspective.

Early infant feeding and swallowing are complex motor processes involving numerous muscles in coordination, e.g. the orofacial muscles as well as the muscles of the pharynx, larynx and esophagus. The newborn's reflexive drinking develops into the ability to ingest pureed complementary food as infancy progresses. Finally, in the last part of the first year of life, a differentiated eating, chewing and swallowing process develops allowing the voluntary intake of different foods of the family diet. The dietary schedule for the first year of life, which describes the recommended nutrition of infants in Germany, corresponds to these milestones in eating development. Disturbances in gross motor development, sensory processing issues, and organic and behavioral problems are known to interfere with the development of eating skills. Swallowing disorders (dysphagia) in children can have a detrimental effect on food intake and pose a serious risk to growth and development. Their prevention treatment requires a multidisciplinary approach with the aim of enabling the child to eat independently in the long term.

Empowering parents to optimize feeding practices with preschool children (EPO-Feeding): A study protocol for a feasibility randomized controlled trial.

BACKGROUND: Parental feeding practices (PFPs) play a key role in fostering preschoolers' dietary habits and in mitigating the risk of childhood obesity. Nevertheless, parents often employ inappropriate feeding practices, leading to children's potential nutrition-related issues. Thus, research is needed to inform interventions that focus on optimizing feeding practices. METHODS: This protocol describes the evaluation of a novel intervention-Empowering Parents to Optimize Feeding Practices (EPO-Feeding Program). The program will be evaluated with a two-arm feasibility randomized controlled trial (RCT) in Yangzhou, China. The program includes four weekly group-based training sessions led by healthcare professionals for parents of preschool children. The intervention incorporates sessions, group discussions, motivational interviewing, and supplementary materials (e.g., key messages and educational videos) aimed at enhancing parents' knowledge, skills, and behaviours related to feeding practices. The primary outcomes include i) implementation feasibility, primarily assessed through retention rates; and ii) program acceptability through a survey and qualitative process evaluation. Secondary outcomes encompass the potential impacts on i) PFPs, ii) parental perception of child weight (PPCW), iii) parenting sense of competence, iv) children's eating behaviours, and v) child weight status. Quantitative analyses include descriptive estimates for evaluating the feasibility and linear mixed regression analysis for testing the potential effects. Qualitative valuation will use thematic framework analysis. DISCUSSION: If this study shows this program to be feasible to implement and acceptable to parents, it will be used to inform a fully powered trial to determine its effectiveness. The research will also help inform policy and practices in the context of child nutrition promotion, particularly regarding implementing group-based training sessions by healthcare providers in similar settings.

A non-microcystin-producing Microcystis wesenbergii strain alters fish food intake by disturbing neuro-endocrine appetite regulation.

Cyanobacterial harmful algal blooms (cHABs) are pervasive sources of stress resulting in neurotoxicity in fish. A member of the widely distributed Microcystis genus of bloom-forming cyanobacteria, Microcystis wesenbergii can be found in many freshwater lakes, including Dianchi Lake (China), where it has become one of the dominant contributors to the lake's recurrent blooms. However, unlike its more well-known counterpart M. aeruginosa, the effects of dense non-microcystin-containing M. wesenbergii blooms are seldom studied. The disturbance of appetite regulation and feeding behaviour can have downstream effects on the growth of teleost fish, posing a significant challenge to aquaculture and conservation efforts. Here we examined the effects of M. wesenbergii blooms on the food intake of Acrossocheilus yunnanensis, a native cyprinid in southern China. This fish species has disappeared in Dianchi Lake, and its reintroduction might be negatively affected by the presence of this newly-dominant Microcystis species. We co-cultured juvenile A. yunnanensis with a non-microcystin-producing strain of M. wesenbergii at initial densities between 5 × 104 and 1 × 106 cells/mL and monitored fish feeding behaviour and changes in neurotransmitter and hormone protein levels. High-density M. wesenbergii cultures increased the feeding rate of co-cultured fish, elevating concentrations of appetite-stimulating signalling molecules (Agouti-related protein and γ-aminobutyric acid), while decreasing inhibitory ones (POMC). These changes coincided with histopathological alterations and reduced somatic indices in brain and intestinal tissues. Given this potential for detrimental effects and dysregulation of food intake, further studies are necessary to determine the impacts of chronic exposure of M. wesenbergii in wild fish.

Breakfast consumption, saturated fat intake, and body mass index among medical and non-medical students: a cross-sectional analysis.

Changes in dietary patterns and body weight have become a focus of research in undergraduate students. This study compared breakfast consumption, intake of foods high in saturated fat, and BMI between medical and non-medical students. A comparative cross-sectional study was conducted in 4,561 Peruvian university students, of whom 1,464 (32.1%) were from the medical field and 3,097 (67.9%) from the non-medical field. We compared the frequency of breakfast consumption (categorized as regular: 6 to 7 days/week; occasional: 3 to 5 days/week; and rarely or never: 0 to 2 days/week) and the frequency of consumption of foods high in saturated fat. We created simple and multiple linear and Poisson regression models with robust variance to evaluate the association of the mentioned variables with academic fields. Non-medical students (Adjusted Prevalence Ratio [PR] = 0.92, 95% CI 0.86-0.99; p = 0.008) were less likely to eat breakfast regularly compared to medical students. Likewise, consumption of foods high in saturated fats was higher in non-medical students (B = 1.47, 95% CI 0.91-2.04; p < 0.001) compared to medical students. Similarly, the mean BMI of these students was significantly higher than that of medical students (B = 0.33, 95% CI 0.12-0.53; p = 0.002). Although medical students reported relatively healthy eating habits and a lower BMI, there is a widespread need to promote improved diet and lifestyle among the entire university population to reduce the risks of communicable diseases and improve quality of life.

Losing sleep influences dietary intake in children: a longitudinal compositional analysis of a randomised crossover trial.

BACKGROUND: Although inadequate sleep increases the risk of obesity in children, the mechanisms remain unclear. The aims of this study were to assess how sleep loss influenced dietary intake in children while accounting for corresponding changes in sedentary time and physical activity; and to investigate how changes in time use related to dietary intake. METHODS: A randomized crossover trial in 105 healthy children (8-12 years) with normal sleep (~ 8-11 h/night) compared sleep extension (asked to turn lights off one hour earlier than usual for one week) and sleep restriction (turn lights off one hour later) conditions, separated by a washout week. 24-h time-use behaviors (sleep, wake after sleep onset, physical activity, sedentary time) were assessed using waist-worn actigraphy and dietary intake using two multiple-pass diet recalls during each intervention week. Longitudinal compositional analysis was undertaken with mixed effects regression models using isometric log ratios of time use variables as exposures and dietary variables as outcomes, and participant as a random effect. RESULTS: Eighty three children (10.2 years, 53% female, 62% healthy weight) had 47.9 (SD 30.1) minutes less sleep during the restriction week but were also awake for 8.5 (21.4) minutes less at night. They spent this extra time awake in the day being more sedentary (+ 31 min) and more active (+ 21 min light physical activity, + 4 min MVPA). After adjusting for all changes in 24-h time use, losing 48 min of sleep was associated with consuming significantly more energy (262 kJ, 95% CI:55,470), all of which was from non-core foods (314 kJ; 43, 638). Increases in sedentary time were related to increased energy intake from non-core foods (177 kJ; 25, 329) whereas increases in MVPA were associated with higher intake from core foods (72 kJ; 7,136). Changes in diet were greater in female participants. CONCLUSION: Loss of sleep was associated with increased energy intake, especially of non-core foods, independent of changes in sedentary time and physical activity. Interventions focusing on improving sleep may be beneficial for improving dietary intake and weight status in children.

Exploring the changing association between parental and adolescent fruit and vegetable intakes, from age 10 to 30 years.

BACKGROUND: Adolescence is a pivotal developmental stage, where escalating rates of overweight and obesity have raised concerns about diet quality and its association with adverse health outcomes. Parents are known to have considerable influence on childhood diet, but how this influence changes as adolescents mature is unknown. This study investigates the association between parental fruit and vegetable (FV) intake and adolescent FV consumption, exploring how this changes across adolescence and when adolescents leave home. METHODS: Adolescents aged 10-30 years (n = 12,805) from the UK Household Longitudinal Study (UKHLS), and their parents, reported FV intakes every 2 years. Multilevel linear regression models were fitted to assess associations between parental and adolescent FV intakes, investigating interactions with age and living arrangement, and adjusting for sociodemographic covariates. RESULTS: Parental FV intake was positively associated with adolescent FV intake (ß = 0.20 [95%CI:0.19,0.22] portions/day), with the strength of this association lowest during early adolescence (10-14 years) and peaking at 17-18 years (ß = 0.30 [95%CI: 0.27,0.33] portions/day). When adolescents no longer lived in the parental home, the association of parental FV intake with adolescent FV consumption decreased, but a positive association was maintained up to age 30 years. CONCLUSIONS: Our findings emphasise the enduring effect of parental FV consumption on adolescent FV consumption, highlighting the potential for interventions to promote increased FV intake, acknowledging the lasting influence of parental diet, even beyond the confines of the parental home.

Stress factors and food purchase prioritization during the pandemic of coronavirus disease 2019.

BACKGROUND: The pandemic of coronavirus disease 2019 (COVID-19) pandemic confinement has an impact on stress levels, which causes changes in food purchase and consumption behaviors. The objective of this study is to associate food purchase prioritization with stress level during the COVID-19 pandemic confinement. METHODS: Multicenter, observational and cross-sectional study, an online questionnaire that included data on sociodemographic variables, stress factors and food purchase prioritization was disseminated through digital platforms and social networks. RESULTS: A number of 6357 participants were included, of whom 83.6% were female, 56.3% were from the middle socioeconomic level, 71.2% had completed higher education and 78.3% had a job. At greater stress levels it was observed a higher prioritization of canned foods (Odds ratio (OR): 1.91, 95% CI: 1.56; 2.34), sweets (OR: 1.58, 95% CI: 1.06; 2.34) and flours (OR: 1.45, 95% CI: 1.25; 1.68). While lower stress levels are associated with nuts (OR: 0.75, 95% CI: 0.66; 0.85), vegetables (OR: 0.82, 95% CI: 0.72; 0.94), and fruits (OR: 0.90, 95% CI: 0.80; 1.01), after adjusting for confounders. CONCLUSIONS: There is an association between food purchase prioritization and stress level during the COVID-19 confinement. At greater stress levels, individuals purchase more food, both healthy and unhealthy. The later may have a negative impact on people's health, leading to or further aggravating malnutrition by excess and nutrition-related noncommunicable diseases.

Effect of maternal eating behaviors and attitudes towards the feeding process on feeding problems of pre-school age children.

BACKGROUND & AIMS: Feeding problems in pre-school children are common and negative maternal feeding practices may even worsen the child's problematic eating behavior. Therefore, investigating the effects of maternal eating behaviors and attitudes towards the feeding process on pre-school children's feeding problems may be helpful for preventing feeding problems. This study sought to investigate the effects of maternal eating behaviors and attitudes towards the feeding process on feeding problems of pre-school children. METHODS: Mothers of 373 children aged 3-6 were included in this cross-sectional study and data was collected by an online questionnaire including the scales of three-factor eating questionnaire (TFEQ), mother's attitudes towards the feeding process (MATFPS) and behavioral pediatric feeding assessment (BPFAS), as well as demographics and anthropometric measures (height and weight). Spearman's rho test was used to calculate correlation coefficients between the TFEQ, MATFP and BPFA scales. In order to identify independent predictors of child feeding behaviors, a multiple linear regression model was used. RESULTS: Results showed that uncontrolled eating subscale was positively (r = 0.160, p < 0.001) and cognitive restriction subscale negatively (r = -0.126, p < 0.05) correlated with MATFP. MATFP was also positively correlated with BPFA (r = 0.368, p < 0.001). Regression analysis indicated that BPFA was significantly predicted by MATFP which was the most important contributor of child feeding problems (ß = 0.24, t = 4.88, p < 0.001). CONCLUSIONS: This study indicated that maternal eating behaviors were related to maternal attitudes towards the feeding process and, mothers' attitudes were associated with feeding problems of their pre-school children.

Real-world survey of eating attitudes and spending behaviors related to healthy foods/supplements in women seeking to become pregnant.

BACKGROUND & AIMS: Since 2022, fertility treatments have been partially covered by insurance in Japan. Women who wish to become pregnant may explore various means of conception as fertility treatments have shown low success rates. Therefore, we aimed to clarify the state of knowledge, behavior, and attitudes toward health foods among women who are actively trying to become pregnant. METHODS: A web-based research company surveyed the eating attitudes and behaviors towards healthy foods of 900 women seeking to become pregnant. Regression analysis for the total amount spent on pregnancy was conducted, with "amount spent on actions undertaken to conceive" as the dependent variable. Multiple regression analysis on actions undertaken to conceive was performed using age, family income, body mass index, duration of hospital visits, duration of actions undertaken to conceive, cumulative amount incurred to conceive, awareness of dietary guidelines, adherence to dietary practices, number of types of health foods and supplements, whether participants considered consumption of nutritious foods and supplements to be important, and cumulative amount spent on healthy foods and supplements. The effect size for the Chi-square test was determined with Cramer's coefficient of association. RESULTS: Increasing age was associated with a longer time to conceive, longer hospital visits, higher conception costs (including fertility treatment), and a higher intake of healthy food products. The number of healthy food types had the greatest impact on the cost incurred to conceive. Folic acid was the most commonly consumed healthy food, followed by iron and calcium. CONCLUSIONS: This study clarified the real-world situation regarding healthy foods for women seeking pregnancy in Japan. The information necessary for pregnant women to select safe healthy foods was clarified, which may lead to the establishment of risk-communication measures to ensure safety.

Patients with Inflammatory Bowel Disease who regularly consume fruits and vegetables present lower prevalence of disease activation: A cross-sectional study.

BACKGROUND: Exclusion diets are common practices among individuals with Inflammatory Bowel Disease (IBD). Reports that certain foods trigger or worsen symptoms are recurrent but lack evidence. The aim of the study was to identify which foods were most frequently avoided by patients with Crohn's Disease (CD) and Ulcerative Colitis (UC) and whether the consumption of any food group was associated with disease activity. METHODS: Cross-sectional study with adult patients seen at an outpatient clinic in a tertiary public hospital. Dietary intake and eating habits were accessed through questionnaires administered via telephone interview. Disease activity and symptoms were assessed using the Harvey-Bradshaw Index (IHB) for CD and the Lichtiger Index (LI) for UC. Poisson regression with a robust variance estimator was used to estimate prevalence ratios. Analyzes were performed using SPSS - Statistical Package for the Social Sciences. RESULTS: The study included 145 patients. Of these, 69.7% avoided certain foods, with citrus fruits and raw vegetables among the most avoided (16.8% and 13.8%, respectively). Regular consumption of fruits (PR = 0.56; CI 95% 0.32-0.97; p = 0.042) and vegetables (PR = 0.56; CI 95% 0.32-0.98; p = 0.045) was associated with a 44% lower prevalence of the active phase of the disease, compared to those who do not consume these foods, adjusted for age, sex and type of disease. Other food items did not present significant associations in the adjusted model. CONCLUSIONS: Fruit and vegetable intake appears to have a protective role in the recurrence of IBD. Excluding foods is a common practice, even among patients in remission, and this should be combated as it can lead to nutritional losses. It is important to reinforce with patients the benefits of a varied and less restrictive diet.

A cross-sectional study on adult lifestyle habits during the COVID-19 pandemic.

COVID-19 has spread and developed into a pandemic disease, forcing countries to impose challenging protocols and lockdowns. This study assessed shopping, food consumption behavior, and feelings in Jordan and several Arab countries during the COVID-19 pandemic. A cross-sectional web-based survey among the Middle East population was conducted using an online questionnaire between July and September 2022. Participants were requested to answer a standardized and validated structured questionnaire. Demographic information, shopping behavior information, and mental health data were requested. A total of 542 respondents were included in the study. During COVID-19 quarantine, participants (68.6%) reported decreased shopping frequency and buying more food than usual (37.5%). Cereals and legumes were the primary food types stored by participants (76.9%). Multiple logistic regression revealed the age of the participant as a significant factor affecting storing of food (being ≤ 25 years old (OR = 0.456, p value = 0.038)). 75.7% of female participants eat less frequently in restaurants than usual. In contrast, among males, 48.5% reported that they eat at restaurants less frequently than usual. The country of residency and gender were the significant factors affecting negative feelings and emotions. Participants in countries other than Jordan had a higher negative feeling score (Beta = 0.086, p value = 0.042). Furthermore, females had a higher negative feeling score (Beta = -0.128, p value = 0.003) as the negative feelings score for females was 3.58 (SD = 5.443). On the other hand, it was 2.10 (SD = 5.091) for males. The COVID-19 pandemic has altered Jordanians' attitudes, shopping, and food consumption habits. Although positive behaviors have improved, such as shopping less frequently, eating home-cooked meals, and dining with family, frequent snacking and food storage have increased. Finally, public awareness of shopping and food consumption habits should be promoted.

Short neuropeptide F in integrated insect physiology. / 昆虫生理中短神经肽Fçš„åŠŸèƒ½ç ”ç©¶è¿›å±•.

The short neuropeptide F (sNPF) family of peptides is a multifunctional group of neurohormones involved in the regulation of various physiological processes in insects. They have been found in a broad spectrum of species, but the number of isoforms in the precursor molecule varies from one to four. The receptor for sNPF (sNPFR), which belongs to the G protein-coupled receptor family, has been characterized in various insect orders and was shown to be an ortholog of the mammalian prolactin-releasing peptide receptor (PrPR). The sNPF signaling pathway interacts with other neurohormones such as insulin-like peptides, SIFamide, and pigment-dispersing factors (PDFs) to regulate various processes. The main physiological function of sNPF seems to be involved in the regulation of feeding, but the observed effects are species-specific. sNPF is also connected with the regulation of foraging behavior and the olfactory system. The influence of sNPF on feeding and thus energy metabolism may also indirectly affect other vital processes, such as reproduction and development. In addition, these neurohormones are involved in the regulation of locomotor activity and circadian rhythm in insects. This review summarizes the current state of knowledge about the sNPF system in insects.
