RESUMO

BACKGROUND: The use of online food ordering applications is widespread; however, to date, there have been no studies on the effect of the menu calorie labeling in online food ordering applications on the consumers' dietary habits and food choices in Saudi Arabia. Therefore, this study aimed to evaluate the response of the consumers to the menu energy-labeling on online food ordering applications in Saudi Arabia by exploring: (a) the consumers' preference and frequency of ordering from online food applications; (b) the consumers' self-reported knowledge, awareness, and interest towards menu calorie information on online food ordering applications; (c) the impact of menu calorie information on online food ordering applications on consumers' food choices. METHODS: This is a cross-sectional study conducted between October and November of 2022. A total of 419 participants were recruited using an online questionnaire. RESULTS: The findings showed that most participants (59%) preferred to order using online food ordering applications. Saving time and effort are the main reasons for using online food ordering applications (61%). Nearly half of the participants (45%) were interested in viewing calorie information on online food ordering applications menus and (47%) did notice calorie information displayed on the menu when ordering from an online food ordering application. Calorie information in online food ordering applications menus is primarily utilized to monitor intake for weight maintenance (19%). The ability to calculate energy requirements and interest in viewing calorie information on online food ordering applications menus were linked to younger age and a higher level of education (p < 0.05). CONCLUSIONS: Overall, consumers showed limited awareness and interest towards the menu calorie information displayed in the online food ordering applications. These findings highlight the importance of developing public health programs to increase public awareness about calorie labeling on menus to aid in the success and effectiveness of the calorie labeling in online food ordering applications as a tool to promote balanced energy intake. Further research is needed to understand the most effective way to deliver calorie information to consumers on an online food ordering application.

RESUMO

The Japanese encephalitis virus (JEV), a mosquito-borne flavivirus that causes viral encephalitis leading to neural damage, is a major threat in most Asian countries. The RNA-dependent RNA polymerase (RdRp) present in the viral genome is the key component for genome replication, making it an attractive target for antiviral drug development. In this study, the natural products from Echinacea angustifolia were retrieved for structure-based virtual screening against JEV-RdRp. The top six compounds (Echinacoside, Echinacin, Rutin, Cynaroside, Quercetagetin 7-glucoside, and Kaempferol-3-glucoside) were obtained based on the highest negative docking score, ADMET (absorption, distribution, metabolism, excretion, and toxicity), and molecular interaction. The computational analysis of these selected compounds against the co-crystallized ligands, i.e., ATP and GTP, were performed. Further, 100 ns molecular dynamic simulation and post-free binding energy calculation of all the selected compounds complexed with JEV-RdRP were performed to check the stability of the complexes. The obtained results showed considerable stability and intermolecular interaction with native ligand-binding site residues of JEV-RdRp. Hence, selected natural compounds are admissible inhibitors of JEV-RdRp protein and can be considered for future antiviral drug development studies.

RESUMO

The objective of the study is to evaluate the effect of food safety and hygiene course on the knowledge, attitudes, and practices of dietetics students. A repeated measure pre/post-intervention study was used to assess the knowledge, attitudes, and self-reported practices regarding food safety and hygiene among undergraduate dietetics students (n = 63) enrolled in a course on food safety and hygiene in Saudi Arabia. Students were asked to complete an online questionnaire divided into five sections that covered key food-safety concepts before and at the end of the course to determine changes in these variables. Overall, students' knowledge, attitudes, and practices improved significantly after attending the course on food safety and hygiene. Scores for total knowledge increased from 16.51±2.60 before the course to 20.60±2.01 after it (p < 0.001). The total score for attitudes improved from 9.16±1.43 before the course to 9.92±0.27 after it (p < 0.001). The total score for practices increased from 11.0±3.10 before the course to 14.78±3.41 after it (p < 0.001).The course on food safety and hygiene helped to improve the knowledge, attitudes, and self-reported practices of food safety by dietetics students.

RESUMO

The chicken gut is the habitat to trillions of microorganisms that affect physiological functions and immune status through metabolic activities and host interaction. Gut microbiota research previously focused on inflammation; however, it is now clear that these microbial communities play an essential role in maintaining normal homeostatic conditions by regulating the immune system. In addition, the microbiota helps reduce and prevent pathogen colonization of the gut via the mechanism of competitive exclusion and the synthesis of bactericidal molecules. Under commercial conditions, newly hatched chicks have access to feed after 36-72 h of hatching due to the hatch window and routine hatchery practices. This delay adversely affects the potential inoculation of the healthy microbiota and impairs the development and maturation of muscle, the immune system, and the gastrointestinal tract (GIT). Modulating the gut microbiota has been proposed as a potential strategy for improving host health and productivity and avoiding undesirable effects on gut health and the immune system. Using early-life programming via in ovo stimulation with probiotics and prebiotics, it may be possible to avoid selected metabolic disorders, poor immunity, and pathogen resistance, which the broiler industry now faces due to commercial hatching and selection pressures imposed by an increasingly demanding market.

RESUMO

BACKGROUND: Few studies have investigated the knowledge and attitudes towards the nutrition facts label, the nutrient content and health claims (NHCs) among consumers from different countries/cultures. METHODS: This cross-sectional study assessed the knowledge and self-reported use of the nutrition facts label and NHCs among Saudi adults. A total of 722 participants were recruited using an online questionnaire. RESULTS: Total knowledge score was 5.8 ± 2.5/13 points (45%). Approximately, 18%, 77%, and 5% of the participants had low, medium, and high levels of knowledge, respectively. Participants were more knowledgeable on the nutrition facts label (2.6 ± 1.6/5 points) and health claims (2.7 ± 1.2/4 points) versus nutrient content claims (0.5 ± 0.7/4 points). The total use score was 20.1 ± 5.7/30 points (67%); approximately, 2%, 61%, and 37% of the participants were classified as low, medium, and high use level, respectively. Participants' use of the nutrition facts label, nutrient content claims, and health claims was 10.0 ± 3.1/15, 6.5 ± 2.2/9, and 3.6 ± 1.8/6 points, respectively. CONCLUSION: This study highlights the need for more education and public awareness programs to enhance consumer knowledge and use of the nutrition facts label and NHCs, and consequently lead to healthy dietary choices.

RESUMO

OBJECTIVE: Preventing a food allergy reaction depends primarily on eliminating allergens from the diet. In October 2019, the Saudi Food and Drug Authority (SFDA) introduced new legislation requiring food establishments providing and selling non-prepacked foods to state the presence of the top fourteen food allergens on their menus. The current study aimed to assess the allergen-labelling knowledge, practices, preferences and perceptions towards the new SFDA allergen-labelling legislation among consumers with food allergy in Saudi Arabia. DESIGN: Observational cross-sectional study using an online questionnaire. SETTING: Saudi Arabia; February - March 2020. PARTICIPANTS: Residents of Saudi Arabia with food allergy (n 427), aged 18-70 years. RESULTS: Among participants, only 28·1 % knew that there were governmental regulations in Saudi Arabia regarding food-allergen labelling and approximately two-thirds (67 %) check labels on prepacked food products for allergens. The majority of the participants preferred food products carrying safety statements (84·1 %) and symbols (80·1 %). A total of 47·1 % were aware that regulations in Saudi Arabia require allergens to be declared in ingredient lists, while 51·3 % were aware that advisory allergen labelling is not required by law. Only 26·2 % were aware of the new SFDA legislation regarding provision of allergen information by food establishments. However, the majority (94·4 %) were supportive of the new legislation, and most of them were more likely to eat at restaurants that reported allergen information for food items on the menu. CONCLUSIONS: The new SFDA food allergen-labelling legislation needs to be more widely and effectively disseminated to increase the level of awareness among adults with food allergy in Saudi Arabia.

RESUMO

Although it is commonly known that viruses cannot multiply in food as they need a living host for growth, adenoviruses and corona viruses can reportedly survive on surfaces and food packages for several days. Therefore, food item mishandling could increase the risk of infection. In this cross-sectional study, we assessed the changes in the food purchasing habits, food safety behavior, and food handling practices among Saudi women during the COVID-19 pandemic. The study included 1356 women who were randomly approached via convenience sampling using an anonymous questionnaire distributed through various social media platforms. The variables were described in terms of frequency and percentage, and the Chi-square test was applied to assess the relationship between the dependent and independent variables. Approximately 62.5% of the participants were aware that SARS-CoV-2 is not transmitted via food. Most participants (90%) reported a shift from outdoor to indoor meal preparation, along with avoidance of visits to grocery stores for food purchase (55%) and increased usage of online grocery delivery services (27%). Most participants obtained good overall scores for food safety behavior during grocery shopping (mean score: 10.83±1.62/12 points, 90.25%), grocery unpacking at home (10.60±2.65/13 points, 81.55%), and personal hygiene (28.84±3.16/36 points, 80%). However, a moderate overall score was obtained for food preparation practices (7.77 ±1.91/12 points, 77.7%). Older and/or retired individuals, patients with chronic diseases, and/or individuals living with children showed better food safety behavior and handling practices compared to their counterparts. This study reported good overall food safety behavior and handling practice scores among participants under most categories studied. However, our results highlight the need for more customized public education programs for Saudi women, who are the primary food handlers in most households, particularly during food preparation, to further improve food safety practices and prevent potential food mishandling, which will eventually help preventing the spread of COVID-19.
