Protective and Therapeutic Effects of Medicinal Plants Against Food Additive-Induced Toxicity.

For thousands of years, people have used medicinal plants and in many parts of the world, traditional medicines continue to play a significant role in the standard treatment of a wide range of illnesses. With changes in modern eating patterns, there has recently been an increase in the use of processed foods. Furthermore, the use of food additives has increased in tandem with the production of processed foods. The dosage levels used for these additives are determined using empirical analyses. However, some additives have demonstrated long-term toxic effects on the human body in toxicity tests. Plants are one of the main sources of biologically active substances and in recent years, many studies have focused on the health benefits of phytochemicals and plant-derived extracts in the treatment and prevention of food additive toxicity. This review clarified studies on several medicinal plants, such as <i>Physalis peruviana</i> L., <i>Jatropha tanjorensis</i>, <i>Cymbopogon citratus</i>,<i> Ficus carica</i>, <i>Rosmarinus officinalis</i> L. and others. The findings presented here demonstrate these plants' efficiency and success in preventing and lowering the toxicity of food additives through antioxidant activity reducing oxidative stress, and reduction in renal and hepatic toxicity. Therefore, these plant extracts have a preventive and therapeutic effect in reducing toxicity and may be the best option for reducing the toxicity of food additives in the future. Moreover, additional research is required to confirm the biologically active components found in medicinal plants that are effective in reducing this toxicity.

Phosphorous intake in foods and phosphorus status markers in circulation in the Boston Puerto Rican Health Study.

Phosphorus (P) additives may be deleterious for health. We measured the P content of key foods, and associations of P intake with biomarkers in the Boston Puerto Rican Health Study (BPRHS). Direct chemical analysis of 92 foods was done with the molybdenum blue spectrophotometric method and inductively coupled plasma mass spectrometry (ICP-MS). A novel algorithm was used to determine bioavailable, natural, and added P. We estimated P intakes from foods in 1323 participants, aged 45-75 y, and associations of these with serum P, fibroblast growth factor 23 (FGF23), parathyroid hormone (PTH), and Klotho. Relationships between intakes and status markers were assessed with Pearson's correlations and t-tests. Our food analyses generally support P values in the USDA nutrient database, with the exceptions of American and cheddar cheese, which had more P than in the database. Women had higher added P intake than men, and younger participants had higher added P than those older. Total P intake tended to be positively associated with serum P and klotho, and inversely associated with PTH, but relationships were not strong. Puerto Rican adults have high intake of additive P. Culturally sensitive interventions that highlight dietary quality are needed.

The key to intestinal health: a review and perspective on food additives.

In this review, we explore the effects of food additives on intestinal health. Food additives, such as preservatives, antioxidants and colorants, are widely used to improve food quality and extend shelf life. However, their effects on intestinal microecology May pose health risks. Starting from the basic functions of food additives and the importance of intestinal microecology, we analyze in detail how additives affect the diversity of intestinal flora, oxidative stress and immune responses. Additionally, we examine the association between food additives and intestinal disorders, including inflammatory bowel disease and irritable bowel syndrome, and how the timing, dosage, and individual differences affect the body's response to additives. We also assess the safety and regulatory policies of food additives and explore the potential of natural additives. Finally, we propose future research directions, emphasizing the refinement of risk assessment methods and the creation of safer, innovative additives.

Palladium­zinc ferrite varnished hydroxyapatite spherocuboids for electrochemical detection of carcinogenic food preservatives.

The demand for processed foods relies heavily on synthetic antioxidants like TBHQ and BHA to prevent spoilage. However, their excessive use poses health risks, prompting regulatory measures in many countries to ensure food safety. In this concern, a proficient electrochemical sensor for the simultaneous detection of tert-butylhydroquinone (TBHQ) and butylated hydroxyanisole (BHA) was designed. A comparatively greener hydroxyapatite (HAP) supported zinc ferrite (ZF) nanosensor was developed with conducting coating of Pd nanoparticles. A consolidated and mechanistic approach was opted to reduce the band gap and agglomeration the magnetic ZF nanoparticles. The interesting spherocuboidal morphology of the synthesized nanocomposite with good porosity enhanced the detection performance of the sensor. The proposed platform displayed good detection limits of both TBHQ and BHA (0.73 and 5.6 nM for TBHQ and BHA, respectively). The nanosensor successfully detected TBHQ and BHA in food samples proved its potential for the development of commercially competitive sensor.

Machine learning prediction of Leuconostoc spp. growth inducing spoilage in cooked deli foods considering the effect of glycine and sodium acetate.

To control spoilage by lactic acid bacteria (Leuconostoc spp.) in cooked deli food, various combinations of environmental and/or intrinsic factors have been employed based on hurdle technology. Since many factors and their combinations greatly influence Leuconostoc spp. growth, this study aimed to develop a machine learning model based on the experimentally obtained growth kinetic data using extreme gradient boosting tree algorithm to quantitatively and flexibly predict Leuconostoc spp. growth. In particular, effects of sodium acetate (0-1.5%) and glycine (0-1.5%), which are frequently used food additives in the Japanese food industry, on the growth of Leuconostoc spp. in cooked deli foods were examined with combination of temperature (5-25 °C) and pH (5.0-6.0) conditions. The developed machine learning model to predict the number of Leuconostoc spp. over time successfully demonstrates comparable accuracy in culture media to the conventional Baranyi model based prediction. Furthermore, while the accuracy of the prediction by the machine learning model for cooked deli foods such as potato salad, Japanese simmered hijiki, and unohana evaluated by the proportion of relative error within the acceptable prediction range was 98%, the accuracy of the conventional Baranyi model based prediction was 89%. The developed machine learning model successfully and flexibly predicted the growth of Leuconostoc spp. in various cooked deli foods incorporating the effect of food additives, with an accuracy comparable to or better than that of the conventional kinetic-based model.

A Schiff-Base Molecular Probe for Selective Fluorescence Sensing of Maleic Acid with Recognition of Maleic Acid in Food Additives and Cell Imaging.

The 2,4-dinitrophenylhydrazine based Schiff base (L) acts as an effective fluorescence sensor for the selective detection of maleic acid. The detection limit of L towards maleic acid is observed to be 1.29 × 10-7 M. A 1:1 binding stoichiometry between L and maleic acid was obtained using Bensi-Hilderbrand method. The binding constant (Ka) was measured to be 5.17 × 106 M-1. The sensing behavior of L was confirmed through analysis using FT-IR, DLS and SEM analysis, alongside DFT calculations. Theoretical assessments clearly suggest that the L's mono-protonation and complexation in the solvent medium are the primary mechanisms in the sensing process. Additionally, L is used to imaging the maleic acid in living cells, demonstrating its potential biological uses. In addition, recognition of maleic acid in food additives was reported.

Knowledge, attitude and purchasing behavior of Saudi mothers towards food additives and dietary pattern of preschool children.

Background: There are over 506 children's products containing one or more types of additives. Maternal awareness of these additives is essential for the health of preschool-aged children, as this period is vital for children's growth and development. This study aims to assess the knowledge, attitudes, and purchasing behaviors related to food additives among mothers living in the western region of Saudi Arabia, as well as the dietary patterns of preschool children. Method: A cross-sectional study was conducted using an online survey with a convenience sample of 521 mothers of preschool-aged children (3-5 years old). The survey gathered data on the child's age, number of children, the youngest child's weight and height, food intolerance, tooth decay, as well as the dietary patterns of preschool children. It also assessed the mother's knowledge, attitude, and purchasing behaviors related to food additives. Results: The study found that 46.6% of mothers demonstrated good knowledge of food additives, while 56.0% demonstrated fair attitudes and 78.5% good purchasing behavior regarding additives. Additionally, the majority of mothers reported favorable dietary patterns for their preschool-aged children. "Biscuits and crackers" had the highest consumption frequency (4.98 ± 1.50), with 36.7% of children consuming them once daily, while "Soft beverages" had the lowest consumption frequency (2.73 ± 2.04), with 46.6% of children never consuming them. Statistically significant differences were identified between mothers' knowledge and their age, education level, occupation status, and economic status (p < 0.05). ANOVA results also indicated a statistically significant difference between mothers' attitudes and occupation status (p < 0.05). Furthermore, there were significant positive correlations between mothers' knowledge of food additives and their attitudes (r = 0.293) and purchasing behaviors (r = 0.284) related to additives. Conclusion: The findings suggest that mothers possess a relatively good level of knowledge of food additives and hold fair attitudes toward them, tending to result in healthier purchasing behaviors and dietary practices for their preschool-aged children. To increase awareness, nutrition intervention programs are required across various socio-economic groups of mothers in the western region of Saudi Arabia. These programs can significantly contribute to promoting healthier dietary practices for preschool-aged children and improving overall family health and well-being.

Influence of Dietary Heritage in a Restricted Geographic Area and Role of Food Additives on Risk of Recurrent Kidney Stone.

Dietary factors may be implicated in the formation of kidney stones and should be closely monitored. To achieve this aim, patients are routinely assessed by means of generic dietary recall, a tool widely used by authors in a range of extensive patient populations to record food intake; the findings obtained, however, may be skewed due to dietary variations and underestimation of the effect of food additives. Fifty Frequent Kidney Stone Formers (FKSFs, mean age: 54.3 ± 13.9 years) with normal kidney function, absence of comorbidities, and reliable compliance were selected from a total of 68 patients' resident in Sardinia, an Italian island where genetic admixtures have been relatively rare for generations. The study, conducted from 1 January 2020 to 31 December 2023, was aimed at assessing nutritional values based on the meticulous recording of food quantities, quality, and potential modifications related to food preparation. Patients were selected during an initial clinical check-up and all efforts made to ensure they were capable of reliably recording all food and drinks consumed. A seven-day food diary was provided in which food and drink intake and their impact on 24 h urine output was recorded. The following parameters were measured in both foods and urine output: citrates, oxalates, calcium, phosphorous, uric acid, proteins and nitrogen compounds, magnesium, sulfates, potassium, carbohydrates, free fatty acids. Study outcomes established the presence of hypocitraturia, hyperoxaluria, hypercalciuria, and moderately high levels of nitrogen compounds. Univariate analysis followed by multivariate analysis for further confirmation were performed and the following observations made. Citrate intake correlated with citraturia but did not promote oxaluria; calcium intake promoted onset of sulfaturia, azoturia, and ammoniuria, whilst magnesium correlated with magnesiuria but not with oxaluria, calciuria, phosphaturia, and azoturia; sulfate intake elicited onset of azoturia but not kaliuresis; potassium intake promoted oxaluria and protein intake resulted in onset of ammoniuria and azoturia. (A) The chemical composition of urine based on dietary intake is hard to predict without taking into account the presence of dietary and urinary interferents; (B) the geographic isolation of patients studied underlines the importance of epigenetics in maintaining a traditional dietary heritage. (C) Moreover, the widespread use of food additives should consistently be taken into account to ensure a correct diagnosis of FKSF and set up a valid treatment plan.

The first case of erythritol-induced anaphylaxis in Europe diagnosed with skin tests and basophil activation tests.

The use of erythritol as a food sweetener has spread significantly from Japan throughout the world. We describe a case of severe anaphylaxis due to immediate-type allergy to erythritol that was diagnosed with in vitro basophil activation tests and in vivo skin tests.

ChemSweet: An AI-driven computational platform for next-gen sweetener discovery.

Nowadays, the overconsumption of artificial sweeteners and their related adverse health impacts have proposed an urgent need to develop safe and healthy alternatives. Herein, we introduce ChemSweet, an AI-based platform for the rapid discovery of potential sweet molecules (http://chemsweet.ddai.tech) with the consideration of their physicochemical properties, sweetness profile, and health risks at the same time. Machine learning prediction models of four important physicochemical and four toxicity properties were established and integrated with the platform to evaluate the candidate molecules' biosafety and stability during the processing processes. Then, a new sweet taste prediction system was developed which ensures the sweet evaluation of six specific kinds of sweeteners. To facilitate the practical application of ChemSweet, the SuperNatural database was integrated for the rational screening of promising new sweeteners. We successfully identified 294 potential sweeteners that simultaneously meet the multiple anticipated criteria. We believe that ChemSweet will serve as a useful tool for identifying safe and healthy sweeteners while reducing the timeframe and high experimental costs.

Food Additives' Impact on Gut Microbiota and Metabolic Syndrome: A Systematic Review.

The human gut microbiota (GM) might play a significant role in the development or remission of metabolic syndrome (MetS) and associated disorders. Contributing factors include diets rich in unhealthy, processed foods that contain preservatives, emulsifiers, and stabilizers. Diet influences the GM's composition, diversity, and species richness in a time-dependent manner. Food additives can alter the GM and contribute to the pathophysiology of MetS by disrupting the intestinal barrier and inducing low-grade systemic inflammation. Our systematic review aims to clarify the relationships among food additives, GM, and MetS. We summarize current knowledge on how food additives interact with GM and the pathogenic role of the microbiota in the development of MetS, including obesity and type 2 diabetes. This review also discusses how disturbances in GM caused by stabilizers and emulsifiers may link to MetS, highlighting the impact of this condition on the development of diabetes and obesity. Furthermore, this review seeks a detailed explanation of how dietary choices related to GM dysbiosis may contribute to MetS. However, more comprehensive and well-designed in vitro, animal, and clinical studies are needed for a better understanding, as research on the role of GM in MetS is still emerging.

The main objective is to demonstrate how these approaches can contribute to a more sustainable food system by reducing environmental impacts and enhancing resource efficiency. Novel contributions of this study include the development of bioproducts from various food waste streams, highlighting the potential of underutilized resources like bread and jackfruit waste. Through case studies and experimental findings, the paper illustrates the successful application of green techniques, such as microbial fermentation and bioprocessing, in valorizing food wastes. The implications of this research extend to policy frameworks, encouraging the adoption of circular bioeconomy models that not only address waste management challenges but also foster economic growth and sustainability. These findings underscore the potential for food waste to serve as a cornerstone in the transition to a circular, regenerative economy.

Fabrication of copper tungstate nanoparticles on screen printed carbon electrode: A disposable strip for the electrochemical detection of the food additive tertiary Butylhydroquinone.

Food additives enhance sensory pleasure and improve marketability in food product formulations, yet their potential health risks are highly consequential. Tertiary butylhydroquinone (TBHQ), in this regard, has a controversial reputation owing to its neurotoxic effects, which include convulsions and other chronic issues. This situation underscores the need for an advanced electrochemical sensing platform. The current study advocates the utilization of copper tungstate nanoparticles to enhance the sensitivity, selectivity, and efficiency in TBHQ detection, thus addressing the challenges posed by the excessive use of additives and safeguarding the integrity of the food supply chain. Hydrothermally synthesized CuWO4 nanoparticles exhibited superior physicochemical and morphological characteristics, bringing about wide linear response ranges (0.01 to 789 µM), high selectivity, excellent anti-interference capabilities, and a low detection limit of 0.9 nM (S/N = 3). The CuWO4 modified screen printed carbon electrode (SPCE) presents promising recovery ranges in food samples, facilitating real-time monitoring and streamlining the quality assessment of food additives.

Ultra-processed foods, allergy outcomes and underlying mechanisms in children: An EAACI task force report.

BACKGROUND: Consumption of ultra-processed foods [UPFs] may be associated with negative health outcomes. Limited data exist regarding the potential role of UPFs in the occurrence of allergic diseases. The underlying mechanisms underpinning any such associations are also poorly elucidated. METHODS: We performed a systematic review and narrative evidence synthesis of the available literature to assess associations between UPF consumption and pediatric allergy outcomes (n = 26 papers), including data on the association seen with the gut microbiome (n = 16 papers) or immune system (n = 3 papers) structure and function following PRISMA guidelines. RESULTS: Dietary exposure to fructose, carbonated soft drinks, and sugar intake was associated with an increased risk of asthma, allergic rhinitis, and food allergies in children. Commercial baby food intake was associated with childhood food allergy. Childhood intake of fructose, fruit juices, sugar-sweetened beverages, high carbohydrate UPFs, monosodium glutamate, UPFs, and advanced glycated end-products (AGEs) was associated with the occurrence of allergic diseases. Exposure to UPFs and common ingredients in UPFs seem to be associated with increased occurrence of allergic diseases such as asthma, wheezing, food allergies, atopic dermatitis, and allergic rhinitis, in many, but not all studies. CONCLUSION: More preclinical and clinical studies are required to better define the link between UPF consumption and the risk of allergies and asthma. These observational studies ideally require supporting data with clearly defined UPF consumption, validated dietary measures, and mechanistic assessments to definitively link UPFs with the risk of allergies and asthma.

Dietary burden of phosphorus and aluminum in ready-to-eat wheat flour tortillas exceed that of corn tortillas: Implications for patients with renal or cardiovascular disease.

Ready-to-eat, shelf-stable tortillas contain several phosphorus- and aluminum-containing additives that may increase the risk of adverse events in patients with chronic kidney disease (CKD). The present study analyzes and compares the elemental content of wheat flour and corn tortillas with special reference to dietary aluminum and phosphorus burden. Twenty-one elements were quantified by ICP-MS and ICP-OES in 14 corn and 13 wheat flour tortilla brands purchased from local supermarkets in Southern California. The aluminum and phosphorus concentrations of many ready-to-eat tortilla brands can present a daily dietary load of up to approximately 100 mg aluminum and 700 mg phosphorus based on an average daily tortilla intake of 330 grams. Ready-to-eat wheat flour tortillas generally had more phosphorus than corn tortillas. Tortillas with aluminum listed as a food additive contained a higher aluminum content than those without such listing, exceeding the tolerable weekly intake. Despite conventional wisdom that CKD patients should avoid phosphorus-rich corn tortillas, ready-to-eat wheat flour tortillas consistently had a higher aluminum and phosphorus content due to additives. CKD patients and healthcare providers should pay attention to food labels, and regulatory authorities should monitor the use of approved food additives and mandate food label warnings for patients at risk.

Correct labelling? A full analytical pathway for silica and titania particles in food products.

Introducing particles as additives, specifically engineered nanoparticles, in the food industry has improved food properties. Since 2014, alongside the presence of these added particles, there has been a mandatory requirement to disclose if those additives are nanomaterials in the ingredient list of food products. However, detecting and characterizing nanomaterials is time-consuming due to their small sizes, low concentrations, and diverse food matrices. We present a streamlined analytical process to detect the presence of silica and titania particles in food, applicable for food regulation and control. Using X-ray Fluorescence Spectrometry for screening enables quick categorization of inorganic particles labeling accuracy, distinguishing products with and without them. For the former, we develop matrix-independent digestion and introduce time-effective statistics to evaluate the median particle size using a reduced number of particles counted, ensuring accurate "nano" labeling. Through the implementation of this work, our objective is to simplify and facilitate verifying the proper labeling of food products.

Comparative omics directed gene discovery and rewiring for normal temperature-adaptive red pigment synthesis by polar psychrotrophic fungus Geomyces sp. WNF-15A.

The Antarctic fungus Geomyces sp. WNF-15A can produce high-quality red pigments (AGRP) with good prospects for the use in food and cosmetic area. However, efficient AGRP synthesis relies on low-temperature and thus limits its industrial development. Here genome sequencing and comparative analysis were performed on the wild-type versus to four mutants derived from natural mutagenesis and transposon insertion mutation. Eleven mutated genes were identified from 2309 SNPs and 256 Indels. A CRISPR-Cas9 gene-editing system was established for functional analysis of these genes. Deficiency of scaffold1.t692 and scaffold2.t704 with unknown functions highly improved AGRP synthesis at all tested temperatures. Of note, the two mutants produced comparable levels of AGRP at 20 °C to the wild-type at 14 °C. They also broke the normal-temperature limitation and effectively synthesized AGRP at 25 °C. Comparative metabolomic analysis revealed that deficiency of scaffold1.t692 improved AGRP synthesis by regulation of global metabolic pathways especially downregulation of the competitive pathways. Knockout of key genes responsible for the differential metabolites confirmed the metabolomic results. This study shows new clues for cold-adaptive regulatory mechanism of polar fungi. It also provides references for exploitation and utilization of psychrotrophic fungal resources.

Is there an "optimal" diet for prevention of inflammatory bowel disease?

Nutritional epidemiological studies have evolved from a focus of single nutrients to diet patterns to capture the protective role of healthy diets on chronic disease development. Similarly, in inflammatory bowel disease (IBD), a healthy diet may be protective against its development in individuals with genetic susceptibility, but the definitions of the optimal diet pattern deserve further exploration. Hence, this review article presents evidence, mainly from prospective cohort studies, for the role of diet quality based on adherence to dietary guidelines, traditional and modern diet patterns in the prevention of IBD. Findings from a limited number of studies on diet quality suggest that high diet quality scores are associated with lower risk of developing Crohn's disease, but the data are inconsistent for ulcerative colitis (UC). There are signals that a Mediterranean diet pattern reduces the risk of Crohn's disease but, again, the data are inconsistent and further studies are much needed. Finally, the evidence is conflicting regarding the role of food additives, with difficulties in the assessment of their intake, namely non-nutritive sweeteners and emulsifiers, precluding accurate assessment of a relationship with IBD risk. In contrast, emerging evidence for a role of ultra-processed food in the development of Crohn's disease but not UC is identified. Given the potential influence of diet quality, a Mediterranean diet and ultra-processed food intake on the risk of Crohn's disease, assessment and implementation of dietary advice for these patients need to be tailored. The search for an optimal diet for UC remains elusive and further research for increasing the evidence in the area is greatly needed.

Fast Determination of Eleven Food Additives in River Water Using C18 Functionalized Magnetic Organic Polymer Nanocomposite Followed by High-Performance Liquid Chromatography.

A novel magnetic nanomaterial with Fe3O4 as the core, PS-DVB as the shell layer, and the surface modified with C18 (C18-PS-DVB-Fe3O4) had been synthesized by seeded emulsion polymerization. C18-PS-DVB-Fe3O4 retains the advantages of the chemical stability, large porosity, and uniform morphology of organic polymers and has the magnetic properties of Fe3O4. A simple, flexible, and efficient magnetic dispersive solid phase extraction (Mag-dSPE) method for the extraction of preservatives, sweeteners, and colorants in river water was established. C18-PS-DVB-Fe3O4 was used as an adsorbent for Mag-dSPE and was coupled with high-performance liquid chromatography (HPLC) to detect 11 food additives: acesulfame, amaranth, benzoic acid, tartrazine, saccharin sodium, sorbic acid, dehydroacetic acid, sunset yellow, allura red, brilliant blue, and erythrosine. Under the optimum extraction conditions, combined with ChromCoreTMAQC18 (5 µm, 4.6 × 250 mm), 20 mmol/L ammonium acetate aqueous solution and methanol were used as mobile phases, and the detection wavelengths were 240 nm and 410 nm. The limits of detection (LODs) of 11 food additives were 0.6-3.1 µg/L with satisfactory recoveries ranging from 86.53% to 106.32%. And the material could be reused for five cycles without much sacrifice of extraction efficiency. The proposed method has been used to determine food additives in river water samples, and results demonstrate the applicability of the proposed C18-PS-DVB-Fe3O4 Mag-dSPE coupled with the HPLC method to environment monitoring analysis.

A comprehensive review of the application of Zr-based metal-organic frameworks for electrochemical sensors and biosensors.

A family of inorganic-organic hybrid crystalline materials made up of organic ligands and metal cations or clusters is known as metal-organic frameworks (MOFs). Because of their unique stability, intriguing characteristics, and structural diversity, zirconium-based MOFs (Zr-MOFs) are regarded as one of the most interesting families of MOF materials for real-world applications. Zr-MOFs that have the ligands, metal nodes, and guest molecules enclosed show distinct electrochemical reactions. They can successfully and sensitively identify a wide range of substances, which is important for both environmental preservation and human health. The rational design and synthesis of Zr-MOF electrochemical sensors and biosensors, as well as their applications in the detection of drugs, biomarkers, pesticides, food additives, hydrogen peroxide, and other materials, are the main topics of this comprehensive review. We also touch on the current issues and potential future paths for Zr-MOF electrochemical sensor research.
