Child-targeted foods in the Portuguese market 2024: Nutritional characteristics and claims

Abstract Background Excessive consumption of high-energy products with high saturated fats, sugars, and salt contents, contribute to the prevalence of overweight, obesity and other related diseases in Portugal, especially among children. Children represent a vulnerable group whose food choices are significantly influenced by advertisements and marketing methods that often promote highly palatable and less healthy foods. This study aimed to assess the nutritional characteristics of visually appealing products targeted at children in Portugal and analyse nutritional, health, and other mentions and claims, as well as icons present in the package. The goal is to contribute to the promotion of healthier food choices and inform public health policies. Methods Nutritional information and mentions/claims from child-targeted foods, featuring labels with cartoons and other appealing images, were collect. These were compared with the reference values (RV) of Integrated Strategy for the Promotion of Healthy Eating (EIPAS) and of Directorate-General of Health Label Decoder (RVLD), as well as the limit values (LV) defined by a Portuguese law related to restrictions on food advertising aimed at children. Results 247 products from six categories were monitored. Only 1.2% met the EIPAS RV for sugar and salt evaluated together, while 10.1% complied with the law LV. According to the RVLD, 19.0%, 26.3%, 49.4%, and 0.4% of the products presented high levels of fat, saturates, sugars, and salt, respectively. The majority of the products (68.0%) had one or more types of mentions/claims, predominantly nutritional (64.3%) and all featured one or more icons, with 10.5% being licensed. Conclusions The majority of these pre-packed child-target foods do not have a healthy nutrient profile. In this context, public health actions, namely legislative measures to further regulate food marketing and labeling elements aimed at children along with literacy and product reformulation initiatives are essential. Key messages • The child-targeted food products in the Portuguese market present inadequate nutritional profiles. • Public health actions are needed to promote healthier food choices and protect children from foodborne non-communicable diseases.

Stakeholder-based management of ecosystem services in agricultural areas: Integrating the leader-follower game and a conflict resolution model

Given the substantial effects of agricultural practices on the environment, this paper introduces a novel stakeholder-based framework for assessing the ecosystem services (ESs) provided by agricultural areas. Ecosystem services include essential functions such as water supply, food production, carbon storage, soil erosion control, and habitat support. In addition to ESs, water footprint is also taken into account to evaluate the impacts of agricultural activities on water resources. Some of the mentioned ESs are assessed using the Soil and Water Assessment Tool (SWAT). Then, by extending and combining the Conflict Resolution Model with the Composition of Probabilistic Preferences (CRMCPP) method and the leader-follower game (LFG), while considering the hierarchical structure of decision-makers, the best scenario for enhancing the ESs is selected.The Zarrinehroud River Basin (ZRB) in Iran has been chosen as a case study to evaluate the performance of the proposed framework, as this basin is vital for supplying water to Lake Urmia, the largest hypersaline lake in the Middle East. In this paper, 16 Water and Environmental Resources Management (WERM) scenarios have been defined according to the Urmia Lake Restoration National Committee (ULRNC) projects. Then, the mentioned ESs have been evaluated under different WERM scenarios. Ultimately, by utilizing the CRMCPP-LFG method and taking into account the hierarchical structure of decision-makers, we can identify the optimal WERM scenario. The criteria for making this decision include various factors, such as ecosystem services and the costs involved in implementing the WERM scenarios. In the selected scenario, the average water inflow into Lake Urmia is projected to rise to 1329 million cubic meters per year, which is 6.3% more than the average inflow in the current condition. Key initiatives in this scenario include reducing cultivated areas, altering irrigation methods, changing crop patterns, and incorporating water-efficient plant species.

Assessing Environmental Concerns, Knowledge and Health Consciousness in Young Adults’ Organic Food Choices

The trend towards buying organic food is declining among young adults, which raises concerns about factors influencing their purchasing behavior. This study investigates factors affecting young adults’ buying behavior of organic food products, including environmental concerns, knowledge, and health consciousness. Survey data was collected from 100 young adults in Selangor, Malaysia. Multiple regression analysis was conducted to analyze the data. The results showed that knowledge about organic food was the strongest predictor of young adults’ organic food purchasing behavior. In addition, concern for the environment had a significant positive influence on young adults’ organic food purchasing behavior, while health consciousness showed no significant influence. These findings offer practical implications for manufacturers: to provide clear product details that can enhance consumers’ knowledge and highlight environmental advantages in marketing strategies to encourage consumption. This study contributes to the literature by highlighting the value of environmental awareness and knowledge of organic food and shedding light on the minor influence of health awareness-a topic that has received less attention in other studies.

Same goal, different measures: Obscure transformation in Japan's food security policy (1970–2020)

AbstractFor decades, the Japanese Ministry of Agriculture has implemented various measures to ensure a stable food supply, considering food security a top priority due to the increasing uncertainty of the global economy. However, the ministry's food security policy has evolved substantially with a disproportionate focus on the domestic production of specific food products. This policy change occurred without being widely recognized by the public, media, or intellectuals. Why has the Agricultural Ministry's policy changed even though its goal has remained the same? By applying both qualitative and quantitative research methods, we investigated the context behind this obscure policy transition. Our findings reveal that, contrary to conventional understanding, this policy shift occurred not so much due to political pressure from the agricultural sector, but mainly because of a change in the definition of a key policy concept (i.e., the food self‐sufficiency rate) in the late 1980s.

Edible coatings for enhancing the shelf-life of foods: meaningful or myth

In the current landscape, effective food management poses significant challenges, particularly in ensuring access to healthy, nutritious diets. Proper handling of food materials during post-harvest stages such as harvesting, packaging, transportation, and distribution are crucial for maintaining food quality, with packaging playing a pivotal role in extending the shelf life of perishable goods. However, the widespread use of conventional plastic packaging has detrimental effects on the environment. As a sustainable alternative, edible coatings have emerged as a promising solution for preserving food over extended periods. While these coatings are primarily used to prolong the shelf life of food products, this review delves deeper into the potential of edible coatings from various perspectives. Edible coatings not only offer multiple benefits such as environmental sustainability and improved food preservation but also present certain limitations. This article provides a comprehensive discussion of different types of edible coatings, their respective advantages and disadvantages, and their application to specific food products. Moreover, the current status and recent research developments surrounding edible coatings are explored, emphasizing their role as a sustainable, eco-friendly alternative to conventional packaging methods that helps reduce environmental pollution and promote a healthier planet.

Sapindaceae fruits: A comprehensive overview on phytochemicals, nutraceuticals and health benefits application

The article delves into the intricate realm of the Sapindaceae family, shedding light on the many phytomedicinal advantages that these fruits offer. This family boasts an array of economically significant fruits, including Litchi (Litchi chinensis), Rambutan (Nephelium lappaceum), Longan (Dimocarpus longan), Guarana (Paullinia cupana), Ackee (Blighia sapida) and Soapberry (Sapindus saponaria), each of which has its own set of medicinal characteristics. The Sapindaceae family, also known as the soapberry family, comprises numerous tropical and subtropical plant species known for their phytochemical properties and potential health benefits. Despite the well-known medicinal properties of Sapindaceae fruits, there is a lack of a comprehensive compilation that combines knowledge about their important components, nutritional value, traditional value and medicinal properties. This review aims to address this gap by providing assessments of the medicinal potential of Sapindaceae fruits and their prospects as food products. The study focuses on the chemicals, nutrients and medicinal properties of Sapindaceae fruits, excluding studies lacking therapeutic relevance. Findings show that Sapindaceae fruits contain bioactive compounds such as saponins, flavonoids and phenolic acids, which are antioxidants, anti-inflammatory, anti-cancer, anti-viral, anti-obesity and anti-diabetic. In addition, these fruits are rich in essential nutrients, including vitamins, minerals and dietary fiber, which supports their use as functional foods and vitamins. The review suggests future research on sustainable uptake and development of nutrients from Sapindaceae, which could increase their use in healthcare and potentially lead to the development of cost-effective pharmaceutical products for consumers and the agricultural sector.

Cost-Effective Multispectral Sensor and Artificial Neural Networks for the Detection of Starch Adulteration in Raw Milk

This study aims to detect starch adulteration in dairy products utilizing an artificial neural network (ANN) model. Globally, milk fraud represents a significant challenge to food safety, posing substantial health risks to consumers. In this context, spectral data derived from milk samples with varying starch concentrations were processed using feature scaling and normalization techniques. The ANN model was rigorously trained and validated employing the stratified k-fold cross-validation method, demonstrating exceptional proficiency in detecting starch-adulterated milk samples and effectively differentiating among various starch concentrations. The principal findings indicate that the model achieved 100% accuracy, coupled with high levels of precision, sensitivity, and F1-scores. Future research should explore the application of this model to different types of adulteration and extend its validation on larger datasets. Furthermore, the potential adaptability of this method for other food products and field applications warrants investigation. This study offers valuable insights for milk producers, food safety professionals, and consumers, particularly highlighting the implications for small-scale rural farms, thereby enriching the discourse on food safety within short food supply chains.

Analysis of Factors Affecting the Spatial Association Network of Food Security Level in China

Food security serves as the cornerstone of national security, intricately linked to social stability and economic progress. Currently, with the swift evolutions in social economy, logistics and transport, information dissemination, and technological advancements, there has been a marked increase in the cross-regional flow of food production, distribution, and consumption. Consequently, the spatial interdependence of food security across different regions has grown increasingly salient. This paper investigates the spatial interrelationship of food security levels in China through a network analysis framework, examining its determinants and network dynamics. The findings offer valuable insights for decision-makers aiming to optimize agricultural resource allocation and enhance national food security levels. This research establishes a comprehensive evaluation index system for assessing food security levels in China across four dimensions: production security, distribution security, supply security, and consumption security. Employing data from 30 provinces between 2008 and 2022, the entropy method quantifies food security levels, while a modified gravity model underpins the construction of a spatial association network. This framework subsequently examines the network’s structural characteristics and the factors influencing its formation. The results reveal that: (1) China’s food security levels demonstrate a consistent upward trajectory over the study period, though significant regional disparities persist. The central region surpasses the national average, while the eastern and western regions lag. Recently, the western region has shown accelerated improvements in food security, followed by the central area, with the eastern region maintaining steady growth. (2) A structurally robust spatial correlation network of food security has emerged, characterized by variations in the number of network relationships, fluctuations in network density, and a decline in network efficiency while still exhibiting pronounced small-world characteristics. (3) The network displays a clear core-periphery structure, with Shanghai, Beijing, and Jiangsu positioned centrally, playing pivotal intermediary roles, whereas remote provinces such as Gansu, Ningxia, and Liaoning occupy the periphery. (4) The four major regions demonstrate sparse internal connectivity yet robust inter-regional ties, resulting in pronounced spillover effects. (5) Various factors, including geographic distance, provincial proximity, disparities in economic development levels, variations in marketization, differences in agricultural human capital, and disparities in land productivity, significantly impact the establishment of spatial correlations in food security. The affirmative influences of geographic distance and neighboring relations, along with the beneficial shifts in economic development disparities, suggest that the flow of technology and resources plays a crucial role in reinforcing spatial connections.

A highly sensitive and specific real-time quantitative polymerase chain reaction assay for Perkinsus marinus detection in oysters

Oyster aquaculture is one of the fastest-growing food production industries worldwide; however, it faces a significant challenge from the protist Perkinsus marinus, particularly in the USA. Although several quantitative molecular diagnostic methodologies are available for identifying diseases caused by P. marinus, the primer pairs used therein led to non-specific identification of other Perkinsus spp. Hence, a quantitative real-time PCR (Pm-qPCR) assay specific for P. marinus was developed using a TaqMan-based probe with the internal quencher in this study. A primer pair and probe specific to P. marinus were designed from a hypothetical protein of P. marinus collected from the whole-genome shotgun sequence database of the National Center for Biotechnology Information (NCBI). In silico analysis using homologous sequences of P. olseni and P. chesapeaki confirmed the high specificity of primers designed in this study. The Pm-qPCR assay was performed using seven different strains of P. marinus, P. olseni, and P. chesapeaki, revealing high specificity and sensitivity for detecting only P. marinus strains. In conclusion, it was demonstrated that Pm-qPCR can effectively and accurately diagnose P. marinus with high specificity and sensitivity. This assay is promising for monitoring oyster health and disease management in ecosystems and aquaculture.

Edible caterpillars (Gonimbrasia belina and Gynanisa maja) as emerging source of nutrients and bioactive compounds

Globally, despite the commercial and cultural importance of edible caterpillars (Gynanisa maja and Gonimbrasia belina), comprehensive information on their dietary and therapeutic benefits has not been fully explored. The study was aimed at evaluating the nutritional composition and bioactive compounds profile of two important edible caterpillars (Gonimbrasia belina and Gynanisa maja) in Africa. Our results demonstrated that G. belina and G. maja are capable of amplifying host plant protein (17 %) by 4.3-folds [72.8 %] and 3.6-folds [61.3 %], respectively. Lysine (32.6 mg/g), methionine (12.5–27.1 mg/g) and valine (7.7–25.4 mg/g) value were significantly harnessed. Substantial amounts of ω−3 fatty acids (methyl 5Z,8Z,11Z,14Z,17Z-eicosapentaenoate and methyl 9Z,12Z,15Z-octadecatrienoate), minerals [iron (3.6–21.2 mg/100 g), zinc (7.1–17.3 mg/100 g), calcium (55.1–60.4 mg/100 g)] and vitamins [retinol (0.02–0.03 mg/kg), γ tocopherol (0.05–0.07 mg/kg) and α-tocopherol (1.2 mg/kg)] were detected. Important phytochemical [flavonoids: rutin (7.8–20.4 ng/g), quercetin (7.2–9.0 ng/g), luteolin (7.4–7.5 ng/g), apigenin (20.8–28.6 ng/g) and kaempferol (3.3–6.5 ng/g)] and phytosterols [stigmasta-3,5-diene, campesterol and sitosterol] were identified. These findings suggests that both edible caterpillars contain sufficient nutrients and therapeutic compounds, which when integrated into human food products, either whole, in-part, or processed will greatly contribute towards countering nutritional insecurity and improve livelihoods of people in many countries.

Social life cycle sustainability assessment of dried tomato products based on material and process selection through multi-criteria decision making.

Tomatoes are a significant product of the Mediterranean region and a crucial component of the Mediterranean diet. The formulation of dried tomato products enriched with proteins and bioactive compounds could be a strategic approach to promote adherence to the Mediterranean diet. Six different novel tomato products were analyzed using different protein enrichment sources (pea proteins and leaf proteins) and drying technologies (hot-air dryer, microwave vacuum dryer, and conventional dryer). The novelty of this approach lies in combining product-specific criteria with global societal factors across their life cycles. Using 21 criteria and an analytic hierarchy process (AHP) survey of experts, the social sustainability score for each product was determined through a multi-criteria assessment. The tomato product's life cycles have minimal regional impacts on unemployment, access to drinking water, sanitation, or excessive working hours. However, they affect discrimination, migrant labor, children's education, and access to hospital beds significantly. The study identified nutritional quality as the top criterion, with the most sustainable design being a tomato bar enriched with pea protein and processed using microwave vacuum drying. The study revealed that integrating sensory and nutrient compounds into social sustainability assessments improves food sustainability and provides a practical roadmap for social life cycle assessments of food products. It emphasized the importance of considering global social issues when reformulating Mediterranean products to ensure long-term adherence to the Mediterranean diet. Incorporating social factors into sustainability scores can also enhance the effectiveness of product information for conscious customers. © 2024 The Author(s).

Probiotic Characteristics and the Anti-Inflammatory Effects of Lactiplantibacillus plantarum Z22 Isolated from Naturally Fermented Vegetables

Currently, there is increasing interest in the commercial utilization of probiotics isolated from traditional fermented food products. Therefore, this study aimed to investigate the probiotic potential of Lactiplantibacillus plantarum (L. plantarum) Z22 isolated from naturally fermented mustard. The results suggest that L. plantarum Z22 exhibits good adhesion ability, antibacterial activity, safety, and tolerance to acidic conditions and bile salts. We further determined the anti-inflammatory mechanism and properties of L. plantarum Z22 and found that L. plantarum Z22 could significantly reduce the secretion of pro-inflammatory cytokines, including interleukin-6 (IL-6), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and the expression of the pro-inflammatory mediator cyclooxygenase-2 (COX-2) protein in LPS-induced RAW 264.7 cells. In addition, L. plantarum Z22 also effectively inhibited the signaling pathways of nuclear factor κB (NF-κB) and mitogen-activated protein kinases (MAPKs). This effect can be attributed to a decrease in the levels of reactive oxygen species (ROS) and increased heme oxygenase-1 (HO-1) expression. Moreover, whole-genome sequencing revealed that L. plantarum Z22 contains gene-encoding proteins with anti-inflammatory functions, such as beta-glucosidase (BGL) and pyruvate kinase (PK), as well as antioxidant functions, including thioredoxin reductase (TrxR), tyrosine-protein phosphatase, and ATP-dependent intracellular proteases ClpP. In summary, these results indicated that L. plantarum Z22 can serve as a potential candidate probiotic for use in fermented foods such as yogurt (starter cultures), providing a promising strategy for the development of functional foods to prevent chronic diseases.

Organic cropping systems balance environmental impacts and agricultural production

Agriculture provides food to a still growing population but is a major driver of the acceleration of global nutrient flows, climate change, and biodiversity loss. Policies such as the European Farm2Fork strategy aim to mitigate the environmental impact of land-use by fostering organic farming. To assess long-term environmental impact of organic food production we synthesized more than four decades of research on agronomic and environmental performance of the oldest system comparison experiment on organic and conventional cropping systems (DOK experiment). Two organic systems (bioorganic and biodynamic) are compared with two conventional (manure-based integrated and mineral-based) systems all with the same arable crop rotation including grass-clover, and manure from livestock integrated in all except the mineral-based system. Organic systems used 92% less pesticides and 76% less mineral nitrogen than conventional systems. Nitrogen use efficiency, that also considers biological nitrogen fixation, was above 85% for all systems. Organic fertilization with farmyard manure maintained or increased soil carbon and nitrogen stocks in the long term, especially in the biodynamic system with manure compost. Conventional mineral-based cropping reduced soil organic carbon and nitrogen stocks. Higher soil organic carbon stocks in organic cropping did not translate to increased N2O emissions, which were the main driver for 56% lower soil-based, area-scaled climate impact compared to the integrated conventional system with manure. Organic cropping systems, especially compost-based biodynamic, showed enhanced soil health, richness of micro- and macrofauna and weed species. Highest yields were achieved in integrated conventional system, with highest total nitrogen inputs and enhanced soil health compared to pure mineral fertilization. Yet, these benefits come at the cost of lower nitrogen use efficiency and higher N2O emissions. Despite a rigorous reduction of inputs yields of the organic systems achieved 85% of the conventional systems. We demonstrate at field level that organic cropping systems with reduced external nutrient inputs have less climate impact and a larger in-situ biodiversity, while providing a fertile ground for the future development of sustainable agricultural production systems.

Performance Characteristics of the Quantitative Method for Staphylococcus aureus in Food Products Correspond to ISO 16140-3: 2021

Staphylococcus aureus is a pathogenic bacterium that poses significant health risks when present in food products. High levels of Staphylococcus aureus in food can indicate poor hygiene and handling practices during food production, processing, or storage. In order to maintain food safety and quality, verification of the quantitative method of Staphylococcus aureus is very important. Method verification represents a crucial stage in guaranteeing that all employed procedures conform to the necessary criteria for dependable and precise data. Following the guidelines established in ISO 16140-3:2021, method verification is accomplished through the calculation of the Intralaboratory Reproducibility Standard Deviation (SIR) for implementation validation and the eBias value for verifying the suitability of the method for assessing specific food items. This research was conducted with the objective of confirming the ISO 6888-1:2021 as the designated reference method for quantifying Staphylococcus aureus in food products. For the purpose of confirming the implementation of the method, Cheese was utilized as the test food item. In the context of verifying the method's applicability to different food products, a range of items including condensed milk, margarine, baby porridge, cassava chips and ready-to-eat sausage were examined as challenging foods. Every chosen food item was artificially contaminated with Staphylococcus aureus WDCM 00034. The SIR value obtained was 0.04 ≤ 2× 0.11 (the lowest mean of SR value from ISO 6888-1:2021) which indicated that the National Quality Control Laboratory of Drug and Food (NQCLDF), Indonesian FDA was able to implement the method very well. In addition, the eBias value for all types of food tested was below 0.5log10, which showed that the quantitative method for coagulase-positive Staphylococci (Staphylococcus aureus and other types) could be applied in the NQCLDF laboratory for the extensive scope of food.

Enhanced nutritional profile of dehulled peas through fungal fermentation: Impacts on protein, starch, saponins, and total phenolic content

AbstractDehulled peas (DHP) are increasingly popular in food applications, but their integration in food products is limited due to high starch and fiber causing gelling and aggregation during cooking. Additionally, DHP contains saponins (secondary metabolite), contributing to bitter flavors, yet they also hold health benefits. We hypothesize that fungal fermentation could enhance DHP nutritional profile and integration into food products. This study evaluated the effects of six fungal organisms (Aspergillus niger [An], Aspergillus oryzae [Ao], Aureobasidium pullulans [Ap], Neurospora crassa [Nc], Rhizopus microspores var. oligosporus [Ro], Trichoderma reesei [Tr]) on DHP over 120 h of submerged fermentation, evaluating total phenolics, starch, saponins, crude proteins, and overall mass balance. Results from the study demonstrated notable changes post‐fermentation, including increased overall protein content and solubility, decreased starch content, reduced overall mass recovery, and elevated levels of total phenolics and saponins. Filamentous fungi exhibited a significant reduction in starch content, contributing to a substantial reduction in mass recovery (31%–60%) compared to the control. Unexpectedly, saponin concentrations increased (1.5 to 3 folds) during fermentation, possibly attributed to the breakdown of the substrate matrix and release of bound saponins. Total phenolic levels varied among microorganisms, with An and Nc demonstrating the highest increases (6 to 10 folds) as compared to the control. Overall, these findings point to fungal fermentation as a tool for adding value to yellow peas and other crops facing similar processing challenges. Further research is warranted to understand the health impacts and value of these enhancements.

Large language models can help boost food production, but be mindful of their risks

Coverage of ChatGPT-style large language models (LLMs) in the media has focused on their eye-catching achievements, including solving advanced mathematical problems and reaching expert proficiency in medical examinations. But the gradual adoption of LLMs in agriculture, an industry which touches every human life, has received much less public scrutiny. In this short perspective, we examine risks and opportunities related to more widespread adoption of language models in food production systems. While LLMs can potentially enhance agricultural efficiency, drive innovation, and inform better policies, challenges like agricultural misinformation, collection of vast amounts of farmer data, and threats to agricultural jobs are important concerns. The rapid evolution of the LLM landscape underscores the need for agricultural policymakers to think carefully about frameworks and guidelines that ensure the responsible use of LLMs in food production before these technologies become so ingrained that policy intervention becomes challenging.

Development and implementation of a simulated microgravity setup for edible cyanobacteria

Regenerative life support systems for space crews recycle waste into water, food, and oxygen using different organisms. The European Space Agency’s MELiSSA program uses the cyanobacterium Limnospira indica PCC8005 for air revitalization and food production. Before space use, components’ compatibility with reduced gravity was tested. This study introduced a ground analog for microgravity experiments with oxygenic cyanobacteria under continuous illumination, using a random positioning machine (RPM) setup. L. indica PCC8005 grew slower under low-shear simulated microgravity, with proteome analysis revealing downregulation of ribosomal proteins, glutamine synthase, and nitrate uptake transporters, and upregulation of gas vesicle, photosystem I and II, and carboxysome proteins. Results suggested inhibition due to high oxygen partial pressure, causing carbon limitation when cultivated in low-shear simulated microgravity. A thicker stagnant fluid boundary layer reducing oxygen release in simulated microgravity was observed. These findings validate this RPM setup for testing the effects of non-terrestrial gravity on photosynthetic microorganisms.

Digitalization and power shift in the food market

This research explores how smartphone applications impact consumer empowerment in a market where companies have more power than consumers, and consumers distrust companies. We draw on Yuka, a scanner app that allows its 44 million users to access nutritional quality scores and other information on food products. We conducted a thematic text analysis of 1,651 user reviews and 117 media articles. Our results indicate that, in the food market, such apps (1) bring transparency to products, which facilitates better purchasing choices, (2) empower consumers, and (3) trigger a shift in power, forcing companies to improve the quality of their products to regain consumer trust. We discuss the implications for research, practice and policy in light of the increasing demand for healthy, safe food. This situation, where power shifts from traditional market players to new digital players and consumers, generating disruptions and emancipation, could become commonplace in futures of market society.

Sustainable agriculture development for food safety and nutrition

Sustainable agriculture is a type of agriculture which, in addition to producing food and agricultural products, is also economically advantageous for farmers, socially correct, respectful of nature and the environment. Sustainable agriculture contributes to improving the quality of life of both farmers and society. Climate change, economic development and social equity influence the sustainable agriculture and require complex and shared solutions on a large scale. Sustainable agriculture includes different meanings, such as environmental, social and economic perspective. The environmental perspective is related to the development of virtuous processes that respect the planet's resources, the healthiness of the soil and water, guaranteeing the maintenance of biodiversity and avoiding the use of pesticides and chemical agents. The social and economic perspective is the ability to meet the global demand of both industrialized and developing countries by ensuring the improvement of the protection of human rights and solidarity-based economic development, the quality of life of farmers, the ethical treatment of animals. The aim of this work is to discuss the implications and perspectives of sustainable agriculture in relation to food production.

Comparative Analysis of Natural vs. Synthetic Antioxidants in Nigeria

Purpose: The aim of the study was to assess the comparative analysis of natural vs. synthetic antioxidants in Nigeria. Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries. Findings: The study indicated that natural antioxidants, derived from plant sources such as fruits, vegetables, and herbs, are often preferred for their bioavailability and health benefits, including their ability to neutralize free radicals and reduce oxidative stress. They are associated with lower toxicity and potential health-boosting properties, such as reducing the risk of chronic diseases. On the other hand, synthetic antioxidants, which are chemically manufactured, tend to have a more stable and consistent potency, making them more effective in industrial applications like food preservation. However, concerns about their long-term health effects, including potential toxicity and adverse side effects, have led to a growing preference for natural alternatives. While both types play important roles in protecting cells from damage, natural antioxidants are often seen as safer, though their effectiveness can vary depending on the source and concentration. Implications to Theory, Practice and Policy: Free radical theory of aging, phytochemical hypothesis and toxicology of food additives may be used to anchor future studies on the comparative analysis of natural vs. synthetic antioxidants in Nigeria. In practical terms, health professionals should advocate for the incorporation of natural antioxidants into dietary guidelines, emphasizing foods rich in these beneficial compounds, such as fruits, vegetables, and herbs. From a policy perspective, there is a pressing need for regulatory frameworks that impose stricter guidelines on the use of synthetic antioxidants in food products, prioritizing safety assessments and considering long-term health impacts.
