Assessment of food safety in Baghdad, Iraq: A two-year analysis of food samples received by the nutrition research institute

Nutritional Science at the University of Illinois at Urbana-Champaign

The University of Illinois at Urbana-Champaign (UIUC), the land-grant university for the State of Illinois, was founded in 1865, and education in nutrition was recorded as early as 1874. Herein, the contributions of the UIUC to research and graduate training in the field of nutrition are highlighted. Over the past 150 years, faculty members from many academic units have provided foundational nutrition research, including identifying the last essential amino acid, threonine, and establishing chemically defined amino acid diets for chicks, rats, dogs, and cats that led to establishing amino acid requirements for these species. Research on the adverse health effects of trans fatty acids supported their removal from the food system. UIUC has led in the area of functional foods for health, including plant bioactives, soy, and fiber. More recently, UIUC faculty have evaluated the interactions between dietary components and neurocognitive, microbiome, and health outcomes, including cancer. In 2020, the cross-campus Personalized Nutrition Initiative was launched to coordinate interdisciplinary research. The Division of Nutritional Sciences was established in 1968 as one of the country’s first interdisciplinary graduate training programs. The Division of Nutritional Sciences program has conferred over 580 degrees and has implemented innovations in graduate education, many supported by federal training grants and endowed awards and programs.

Citrus nutrition research in northeast India: An overview

History of citrus growing in northeast India is as old as the tradition of citrus as its natural home of citrus hots-spots. Unfortunately, citrus of late is being tagged highly uncomfortable in its natural homeyard in northeast India, with some exceptions in Garo hills of Meghalaya and Pasighat of Arunachal Pradesh. Multiple nutrient deficiencies backed up by staggering nutrient mining have made citrus suffer from both production as well as quality issues, besides other issues of early onset of citrus decline and reduced post -harvest shelf life. Such depleted production incentives have put citrus growing on back-foot. Distinct absence of nutrient diagnostics coupled with lack of balanced fertilization have further hiked the miseries of citrus growers in the region. Citrus -based Soil health Card is another missing link putting citrus growers always managing their citrus orchards with complete guess-work, a complete sorry-state-of-affair, unless something too early and too quickly is done in this direction before it becomes too late and too little. Research need a complete reorientation in their objectivity of citrus nutrition with an eye on organic citrus integrating agroecological considerations using strictly adopted on-farm citrus module coupled with contingency irrigation planning by holding surplus rainwater.

Plasma Branched-Chain Fatty Acids Reflect Dairy-Fat Intake in a Pilot Clinical Trial in Individuals with Prediabetes

Epidemiological studies often rely on fatty acid (FA) biomarkers of dairy-fat intake to represent diet history and to establish associations with cardiometabolic risk factors. However, a more robust body of direct research is needed to validate the currently utilized FA biomarkers as accurate representations of dairy-fat intake. Thus, our objectives were to i) compare the plasma FA profile of individuals with prediabetes following the consumption of a diet with full-fat (3.25%) yogurt (FFY diet) or non-fat yogurt (NFY diet) to evaluate their validity of currently utilized biomarkers and ii) identify additional FAs to serve as potential biomarkers. We hypothesized that the proportion of the unique dairy-derived FAs including odd-chain FAs (13:0, 15:0, 17:0, 19:0, 21:0, 23:0), branched-chain FAs ( iso-13:0, anteiso-13:0, iso-14:0, iso-15:0, anteiso-15:0, iso-16:0, iso-17:0, anteiso-17:0, iso-18:0), and the trans-FAs 16:1 trans-9 and 18:1 trans-11 would increase in plasma total lipids following the consumption of three daily servings of full-fat yogurt for three weeks. Our 8-week randomized, double-masked, controlled crossover study included six men and seven women aged 45-75 years old. Each experimental diet period, NFY diet and FFY diet, was three weeks in length. The arithmetic difference in fat (8% energy) between the NFY diet (30% fat) and the FFY diet (38% fat) was solely due to the dairy fat in the full-fat yogurt. Following each experimental diet period, fasting plasma samples were taken and analyzed for FA composition of plasma total lipids using gas-liquid chromatography. Consumption of the FFY diet resulted in no change in the proportion of total odd-chain FAs or the individual FAs 16:1 trans-9 and 18:1 trans-11, but the proportion of total branched-chain FAs was greater in response to the FFY diet ( P < 0.01). For individual odd-chain and branched-chain FAs, the proportions of iso-17:0 and anteiso-17:0 were greater in response to the FFY diet ( P < 0.01 for both); however, there were no differences in anteiso-15:0 or iso-15:0 proportions by diet. Results from this pilot trial suggest that commonly utilized FA biomarkers may not be suffciently robust to represent dairy-fat intake. Branched-chain FAs should be further explored for alternatives. Funding for this project was provided by National Dairy Council Nutrition Research Funding, a USDA Agriculture and Food Research Initiative National Institute of Food and Agriculture Predoctoral Fellowship, and a fellowship from the University of Vermont’s Food Systems Research Center.

Fish markets facilitate nutrition security in coastal Kenya: Empirical evidence for policy leveraging

Fish markets are key to supporting the availability and accessibility of nutritious food but are often overlooked in food and nutrition research and policy. This study investigated fish markets in coastal Kenya, using data from 223 semi-structured interviews collected through market surveys, and analyzed their potential to meet recommendations for consumption and alleviate malnutrition in a vulnerable coastal population (children under five years). Findings reveal that women small-scale traders dealt in lower quantities of fish per trader than the other traders, yet sold more nutritious fish. Fish shop traders sold enough fish to meet 129% of the recommended intake of fish (10.4 kg cap−1 yr−1) for all people within the assessed towns, whereas women small-scale traders sold enough to meet 84% of the intake. All market traders were key to making nutrient-dense fish available, with a 100 g portion of fish providing at least 25% of required intakes, across five nutrients, and women small-scale traders providing over 25% of required intakes across six nutrients for a child under five years. The average cost of a nutritious portion of fish was KES 31 (USD 0.22), ranging from KES 12 (USD 0.08) to 49 (USD (0.34), which provide 33.3% of the required nutrients (averaged across six nutrients), with nutrient-dense fish being notably cheaper. This study contributes empirical evidence on how territorial fish markets support nutrition, which is important for food policy interventions that promote nutritional literacy, address nutrient gaps, and improve postharvest practices and infrastructure for fish quality and safety in Kenya.

Looking to the future: Agendas, directions, and resources for nutrition research.

The development and progression of nutrition as a scientific field is ever evolving and complex. Although the history of nutrition research began by exploring specific food components, it has evolved to encompass a more holistic view that considers the impact of dietary patterns over time, interactions with the environment, nutrition's role in disease processes, and public policy related to nutrition health. To guide the future direction of nutrition science, both federal and other professional organizations have established agendas and goals. The Strategic Plan for National Institutes of Health Nutrition Research outlines four goals and five cross-cutting research areas that are priorities to explore between 2020 and 2030. Similarly, the American Society for Parenteral and Enteral Nutrition and other governmental and professional organizations have identified priority areas in their research agendas. Rigorous research studies are needed to explore these areas of interest while also considering practical implementation strategies for translating research into practice. Nutrition clinicians are uniquely positioned to lend expertise in the areas of research design, implementation, advocacy and evidence-based practice; there are numerous resources to support practitioners in these endeavors.

Online training needs assessment (TNA) among Municipal Nutrition Action Officers (MNAOs) in the Philippines

Introduction: A training needs assessment (TNA) was conducted by the Department of Science and Technology, Food and Nutrition Research Institute (DOST-FNRI) to design appropriate and relevant trainings for Municipal Nutrition Action Officers (MNAOs). In the Philippines, MNAO is a nutrition officer who serves at the municipal level and is tasked to ensure the localisation of the Philippine Plan of Action for Nutrition (PPAN) in Local Government Units (LGU) to ensure proper implementation of activities on Public Health Nutrition (PHN). Methods: A total of 162 MNAOs in the country answered the online TNA survey conducted from April to May 2023. Results: Based on the results of the TNA survey, there was a need for DOST-FNRI to design and conduct trainings related to the top three core competencies identified by MNAOs: Creating policies and standards related to food and nutrition; advocating legislation, regulation, and nutrition policies; and designing appropriate nutrition information education and communication (IEC) materials. Conclusion: Based on the study results, it is recommended that LGUs allocate funds for capacity building of the public health workforce to create a skilled workforce in the community that will coordinate the formulation, implementation, monitoring, and evaluation of nutrition plans at the municipal level. For future consideration, curriculum design for professional development in public health nutrition should include core competencies on food and nutrition policy programme, nutrition programme management, and IEC development.

Canadian farmers' perceptions of social sustainability in agriculture.

Sustainable food production is an important part of dietetic education and training; however, the focus in the dietetic sphere is often on the environmental aspect. Understanding the multi-dimensional nature of sustainability can enhance dietetic students' sustainability competences-such as empathy and change of perspective, systems thinking, and critical thinking and analysis-to help them in their future careers and strengthen their position in society as trusted and knowledgeable food and nutrition professionals. Enhancing public understanding of sustainable food production is imperative as populations become more urban, are less connected to agriculture, and have expectations for sustainably grown/raised food, often without knowing current food production practices or the multiple aspects of sustainability that must be in place for farmers to meet those demands. The goal of this research was to understand Canadian farmers' perceptions of environmental, economic, and social aspects of sustainable food production. Employing a descriptive qualitative approach and constant comparative analysis, four food and nutrition researchers analyzed interviews from 52 farmers from across Canada. Participants had to be English-speaking, produce food through farming on land, and own or rent the land on which they farm. Telephone/video interviews revealed five overarching social themes: (1) the importance of community and social capital, (2) public perception and social license to operate, (3) lack of infrastructure, and (4) deep connections to personal lives. The final theme, mental health issues (5), reflected the consequences of the multiple sources of stress that can undermine the social sustainability of farmers, farm communities, and food production. These findings may help various audiences appreciate the multiple dimensions of sustainable food production; reflect on their values, perceptions, and actions with regard to agriculture; and enhance their compassion and empathy for all farmers.

The Administration of Intradialytic Parenteral Nutrition Does Not Affect the Anemia Status of Chronic Kidney Disease Patients Undergoing Hemodialysis

Background: Hemodialysis (HD) patients are susceptible to malnutrition, and there is a close relationship between malnutrition and the incidence of anemia. Parenteral nutrition plays a role in treating malnutrition. Objective: This study aims to determine the effect of parenteral nutrition on anemia in HD patients. Methods: Quasi-experimental research which is part of the nutritional research tree at the Hemodialysis Unit of RSUP Dr. Soetomo Surabaya for 3 months. A total of 45 malnourished CKD patients (SGA B & C) undergoing routine HD were included in this study (n=26 received regular diet & education, n=17 received regular diet, education and intradialytic parenteral nutrition, and n=2 dropped out of school due to blood transfusion). Measurements of body mass index (BMI), hemoglobin (Hb), serum iron (SI), and total iron binding capacity (TIBC) were carried out before and 8 weeks after therapy. Between groups used the Mann-Whitney test, while pre and post used the Wilcoxon matched-pairs sign rank test. Results: The treatment group was older than the control group. There was no difference in duration of HD between groups. Intradialytic parenteral nutrition had no effect on BMI (24.71±3.939 vs 24.71±4.026; p=0.3802), Hb (9.746±1.309 vs 9.162±1.960; p= 0.3525), SI (62.33±34.74 vs. 53.78±24.89; p=0.3594), and TIBC (242.8±119.0 vs. 197.3±43, 65; p=0.4258). Conclusion: In HD patients, intradialytic parenteral nutrition for 8 weeks did not affect Hb, SI and TIBC levels. Long-term observations with larger samples are needed to confirm these findings.

Building nutritionally meaningful classification for grocery product groups: the LoCard Food Classification process.

Analysing customer loyalty card data is a novel method for assessing nutritional quality and changes in a population's food consumption. However, prior to its use, the thousands of grocery products available in stores must be reclassified from the retailer's original hierarchical structure into a structure that is suitable for the use of nutrition and health research. We created LoCard Food Classification (LCFC) and examined how it reflects the nutritional quality of the grocery product groups. Nutritional quality was considered the main criterion guiding the reclassification of the 3574 grocery product groups. Information on the main ingredient of the product group, purpose of use and carbon footprint was also used at the more granular levels of LCFC. The main challenge in the reclassification was a lack of detailed information on the type of products included in each group, and some of the groups included products that have opposite health effects. The final LCFC has four hierarchical levels, and it is openly available online. After reclassification, the product groups were linked with the Finnish food composition database, and the nutrient profile was assessed by calculating the Nutrient-Rich Food Index (NRFI) for each product group. sd in NRFI decreased from 0·21 of the least granular level to 0·08 of the most granular level of LCFC indicating that the most granular level of LCFC has more homogeneous nutritional quality. Studies that apply LCFC to examine loyalty card data with health and environmental outcomes are needed to further demonstrate its validity.

Nutrient Intake of Stunted Filipino School-age Children: Results from the 2018-2019 Expanded National Nutrition Survey

Over the last few decades, stunting has decreased worldwide, although the prevalence remains high in underdeveloped and developing countries. A child's healthy growth is a key measure of their overall well-being, and it is directly linked to his or her nutrient intake and resistance to illnesses. This study determined the nutrient intake of stunted Filipino school-age children utilizing secondary data from the 2018–2019 Expanded National Nutrition Survey conducted by the Department of Science and Technology–Food and Nutrition Research Institute. A total of 26,332 5–10-yr-old school-age children were included in the study. The data utilized were nutritional status, socio-economic status and demographic profile, and nutrient intake of school- age children. Stata version 16 was used for all statistical tests, whereas the PC-SIDE software was used for the estimation of the mean usual intake of energy and nutrients. Among stunted school-age children, mean energy, protein, iron, thiamin, riboflavin, niacin, and fat intake were significantly higher among urban households than their counterparts. The proportion of stunted school-age children meeting the recommended intake for energy (9.3%), iron (15%), vitamin A (24.8%), thiamin (27%), and riboflavin (29.8%) were significantly higher in the urban as compared to rural areas. The energy, protein, vitamin A, vitamin C, thiamin, niacin, riboflavin, iron, and calcium intake of stunted school-age children were significantly lower as compared to the non-stunted. The data show that despite the decreasing prevalence of undernutrition in the country, the problem of childhood stunting still persists. Furthermore, non-stunted children only had slightly better nutrient intakes. These urges work on the major determinants of stunting in the Philippines and the implementation of appropriate interventions such as supplementary feeding programs, food production, and nutrition education.

The Effects of Artificial Diets on the Expression of Molecular Marker Genes Related to Honey Bee Health.

Honey bees are commonly used to study metabolic processes, yet the molecular mechanisms underlying nutrient transformation, particularly proteins and their effects on development, health, and diseases, still evoke varying opinions among researchers. To address this gap, we investigated the digestibility and transformation of water-soluble proteins from four artificial diets in long-lived honey bee populations (Apis mellifera ligustica), alongside their impact on metabolism and DWV relative expression ratio, using transcriptomic and protein quantification methods. Diet 2, characterized by its high protein content and digestibility, was selected for further analysis from the other studied diets. Subsequently, machine learning was employed to identify six diet-related molecular markers: SOD1, Trxr1, defensin2, JHAMT, TOR1, and vg. The expression levels of these markers were found to resemble those of honey bees who were fed with Diet 2 and bee bread, renowned as the best natural food. Notably, honey bees exhibiting chalkbrood symptoms (Control-N) responded differently to the diet, underscoring the unique nutritional effects on health-deficient bees. Additionally, we proposed a molecular model to elucidate the transition of long-lived honey bees from diapause to development, induced by nutrition. These findings carry implications for nutritional research and beekeeping, underscoring the vital role of honey bees in agriculture.

Dietary pattern and diversity analysis using DietDiveR in R: a cross-sectional evaluation in the National Health and Nutrition Examination Survey

BackgroundThere are few resources available for researchers aiming to conduct 24-h dietary record and recall analysis using R. ObjectivesWe aimed to develop DietDiveR, which is a toolkit of functions written in R for the analysis of recall or record data collected with the Automated Self-Administered 24-h Dietary Assessment Tool or 2-d 24-h dietary recall data from the National Health and Nutrition Examination Survey (NHANES). The R functions are intended for food and nutrition researchers who are not computational experts. MethodsDietDiveR provides users with functions to 1) clean dietary data, 2) analyze 24-h dietary intakes in relation to other study-specific metadata variables, 3) visualize percentages of energy intake from macronutrients, 4) perform principal component analysis or k-means clustering to group participants by similar data-driven dietary patterns, 5) generate foodtrees based on the hierarchical food group information for food items consumed, 6) perform principal coordinate analysis taking food grouping information into account, and 7) calculate diversity metrics for overall diet and specific food groups. DietDiveR includes a self-paced tutorial on a website (https://computational-nutrition-lab.github.io/DietDiveR/). As a demonstration, we applied DietDiveR to a demonstration data set and data from NHANES 2015–2016 to derive a dietary diversity measure of nuts, seeds, and legumes consumption. ResultsAdult participants in the NHANES 2015–2016 cycle were grouped depending on the diversity in their mean consumption of nuts, seeds, and legumes. The group with the highest diversity in nuts, seeds, and legumes consumption had 3.8 cm lower waist circumference (95% confidence interval: 1.0, 6.5) than those who did not consume nuts, seeds, and legumes. ConclusionsDietDiveR enables users to visualize dietary data and conduct data-driven dietary pattern analyses using R to answer research questions regarding diet. As a demonstration of this toolkit, we explored the diversity of nuts, seeds, and legumes consumption to highlight some of the ways DietDiveR can be used for analyses of dietary diversity.

Exploring the phytochemical and biological properties of Salsola foetida: a promising wild plant from Southeastern Algeria

ABSTRACT This study presents an initial exploration of the phytochemical composition and biological properties of Salsola foetida, a wild plant native to southeastern Algeria. The investigation encompassed an analysis of the biochemical content, phytochemical profile, and bioactivity of the plant’s aerial parts. The biomass of S. foetida was found to comprise 51.2 ± 0.4% ash, with elemental analysis revealing the presence of carbon, oxygen, calcium, sodium, chlorine, magnesium, potassium, and sulfur. Carbohydrates were identified as the predominant constituents, surpassing the levels of proteins and lipids. Phytochemical screening, coupled with Fourier Transform Infrared (FT-IR) analysis, confirmed the presence of various secondary metabolites, including alkaloids and phenols. Reversed-phase high-performance liquid chromatography (RP-HPLC) analysis further delineated a spectrum of phenolic compounds, with rutin emerging as the predominant compound at 1.59 µg/ml. Quantification revealed a noteworthy phenolic content of 67.1 ± 0.2 µg GE/mg ED. The extract exhibited robust radical scavenging effects, with the radical 50% inhibitory concentration (IC50) being 61.8 ± 0.2 μg/ml, along with protective effects against H2O2-induced hemolysis and the ability to reduce ferric ions. Additionally, the extract demonstrated anti-inflammatory, antibacterial, and antidiabetic activities. Notably, it exhibited considerable sunscreen properties, boasting a sun protected factor (SPF) value of 21 ± 1. Overall, S. foetida presents promising antioxidant activity and a spectrum of potential biological activities, underscoring its significance as a novel antioxidant candidate for applications in animal nutrition, medicine, and natural product research.

Why should scientists lead? To underpin policy on marine and polar ecosystems

Abstract I recount my personal history, beginning as a young fisherman, becoming an academic fisheries biologist, and ultimately a leader of institutions dedicated to marine and polar research, higher education, and advising policymakers. After my dissertation in the early 1990s, I embarked on an active research career at the Institute of Marine Research (IMR) in Bergen, Norway, developing a sonar method to estimate the abundance of schooling, pelagic fish. My career then transitioned to middle leadership—15 years as Section Leader and Research Director at IMR—followed by >10 years as a top leader for The University Centre in Svalbard, the National Institute of Nutrition and Seafood Research, and finally the Norwegian Polar Institute. I describe the major challenges, opportunities, and processes these leadership roles have entailed. I hope to send a positive message about the influential role of science, and the necessity of clear communication of results and advice at a time when there is a sense of urgency.

Automated Artificial Intelligence–Based Thai Food Dietary Assessment System: Development and Validation

BackgroundDietary assessment is a fundamental component of nutrition research and plays a pivotal role in managing chronic diseases. Traditional dietary assessment methods, particularly in the context of Thai cuisine, often require extensive training and may lead to estimation errors. ObjectivesTo address these challenges, Institute of Nutrition, Mahidol University (INMU) iFood, an innovative artificial intelligence–based Thai food dietary assessment system, allows for estimating the nutritive values of dishes from food images. MethodsINMU iFood leverages state-of-the-art technology and integrates a validated automated Thai food analysis system. Users can use 3 distinct input methods: food image recognition, manual input, and a convenient barcode scanner. This versatility simplifies the tracking of dietary intake while maximizing data quality at the individual level. The core improvement in INMU iFood can be attributed to 2 key factors, namely, the replacement of Yolov4-tiny with Yolov7 and the expansion of noncarbohydrate source foods in the training image data set. ResultsThis combination significantly enhances the system’s ability to identify food items, especially in scenarios with closely packed food images, thus improving accuracy. Validation results showcase the superior performance of the INMU iFood integrated V7-based system over its predecessor, V4-based, with notable improvements in protein and fat estimation. Furthermore, INMU iFood addresses limitations by offering users the option to import additional food products via a barcode scanner, thus providing access to a vast database of nutritional information through Open Food Facts. This integration ensures users can track their dietary intake effectively, with expanded access to over 3000 food items added to or updated in the Open Food Facts database covering a wide variety of dietary choices. ConclusionsINMU iFood is a promising tool for researchers, health care professionals, and individuals seeking to monitor their dietary intake within the context of Thai cuisine and for ultimately promoting better health outcomes and facilitating nutrition-related research.

Nutrition survey methods and food composition database update of the Korean Genome and Epidemiology Study.

This study presents the nutrition survey methods and the updated food composition database for the Korean Genome and Epidemiology Study (KoGES). The KoGES, which is the largest and longest cohort study in Korea, aims to identify genetic and environmental factors associated with chronic diseases. This study has collected dietary data using a validated semi-quantitative food frequency questionnaire and/or the 24-hour recall method. However, these dietary survey methods use different food composition databases, and their nutritional values are out of date. Therefore, it became necessary to update the food composition database by revising nutrient analysis values to reflect improvements in the performance of food ingredient analysis equipment, revising international values to analysis values of Korean agricultural products, adjusting nutrient units, and adding newly reported nutrients related to chronic diseases. For this purpose, we integrated the different food composition databases used in each nutrition survey, updated 23 nutrients, and expanded 48 new nutrients for 3,648 food items using the latest reliable food composition databases published by national and international institutions. This revised food composition database may help to clarify the relationship between various nutrients and chronic diseases. It could serve as a valuable resource for nutritional, epidemiological, and genomic research and provide a basis for determining public health policies.
