Consumers are increasingly exposed to environmental claims on food products. These claims often lack scientific validation and there are different methodologies that can be used for grounding these claims, which can lead to misleading results. The European Union’s (EU) Environmental Footprint methodology excludes the aggregation of environmental impacts, including damage to human health. This fact reduces transparency and limits the consumers’ ability to make information-based sustainable choices. This study aims to address this issue by calculating aggregated impacts on human health via life cycle assessment (LCA) in the agriculture and food-production sectors. In the study the IMPACT World+ method was used, including trustworthy databases and proper functional unit definition. The assessment encompassed three types of vegetables, four types of fruit, and four types of ready meals. The study also attempts to assess the impact of different farming systems (organic and conventional) on human health. Two standardised functional units, i.e., the unit based on product weight and product energy value were considered for each group of products. Our findings showed significant differences in results when different functional units were used. Additionally, no conclusion could be drawn regarding which farming system is more sustainable. Therefore, it is essential that the regulator clearly defines the criteria for selecting the appropriate functional unit in LCA within the agriculture and food-production sectors. In the absence of these criteria, results should be presented for all alternatives. Although not required by EU regulation, the authors suggest that companies should nevertheless disclose information regarding the environmental impact of agriculture and food production on human health, as this is important for consumers.

The garden Nasturtium (Tropaeolum majus L.) is increasingly consumed worldwide due to its culinary appeal and perceived health benefits. However, the chemical markers underlying its functional properties remain insufficiently characterized. Building on evidence from a recent human pilot study confirming both high acceptability and dietary safety, we conducted a comprehensive volatilomic and phytochemical analysis of T. majus flowers and their juice. Headspace solid-phase microextraction coupled with gas chromatography–mass spectrometry (HS-SPME/GC-MS) was employed to establish the volatilomic fingerprint of floral tissues and juice. Our analysis revealed a striking dominance of benzyl isothiocyanate and benzonitrile, which together accounted for 88% of the total volatile organic metabolites (VOMs) in the juice, 67% and 21%, respectively. In the floral tissues, benzyl isothiocyanate was even more prevalent, representing 95% of the total volatile profile. Complementary in vitro assays confirmed a substantial total phenolic content and strong antioxidant activity in the flowers. These findings provide a robust chemical rationale for the potential health-promoting attributes of T. majus, while identifying key volatilomic markers that could support future functional and safety claims. In parallel, a benefit–risk assessment framework is discussed in accordance with the European Food Safety Authority (EFSA) guidelines for the Qualified Presumption of Safety (QPS) of edible flowers. Given that both benzyl isothiocyanate and benzonitrile are classified as Cramer Class III substances, a conservative intake threshold of 1.5 μg/kg body weight per day is proposed. To enable quantitative exposure modeling and support the derivation of a tolerable daily intake (TDI), future studies should integrate organic solvent-based extraction methodologies to estimate the total volatile load per gram of floral biomass. This would align risk–benefit assessments with the EFSA’s evolving framework for novel foods and functional ingredients. Full article

Wild edible mushrooms (WEMs) are a popular delicacy in Thailand, prized for their unique flavor, texture, and nutritional value. Despite their widespread consumption, there is limited scientific research on their chemical compositions, biological activities, and potential health benefits. To bridge this knowledge gap, a comprehensive study was conducted on sixteen WEM species from ten families—Polyporaceae, Pleurotaceae, Russulaceae, Marasmiaceae, Pluteaceae, Boletinellaceae, Diplocystaceae, Lyophyllaceae, Psathyrellaceae, and Auriculariaceae—commonly found in northern Thailand. The proximate composition varied significantly among the WEM species, particularly in crude protein (12–51% w/w), crude fiber (1–30% w/w), and glucans (4–25% w/w). Astraeus odoratus exhibited the highest phenolic content, while P. cf. portentosus demonstrated the most potent antioxidant activity. WEM extracts also displayed notable inhibitory effects on α-glucosidase (5.82–79.43%) and α-amylase (1.30–90.79%). All extracts induced antioxidant regulators of Nrf2 and NQO1, suggesting that WEMs can help protect cells from oxidative stress, environmental toxins, and xenobiotics from food. Importantly, all extracts maintained high cell viability (>80%), indicating their safety for consumption. Furthermore, the mushrooms demonstrated a strong ability to reduce hepatotoxicity in HepG2 cells induced by tert-butyl hydrogen peroxide, highlighting their potential in preventing liver damage. This study not only underscores the nutritional and health benefits of WEMs but also establishes a vital scientific foundation for future research on their health effects and in vivo applications. In turn, these findings could serve as a crucial resource for optimizing the use of WEMs in ethnic cuisines and strengthening claims regarding their functional food properties. Full article

In recent years, functional foods have garnered increasing scientific and public health interest due to their potential to confer physiological benefits beyond basic nutritional value. International bodies such as EFSA, FDA, and WHO define functional foods as those containing bioactive components that may contribute to the prevention and management of chronic non-communicable diseases, including cardiovascular disease, type 2 diabetes, and certain cancers. The evolving paradigm of “food as medicine” reflects a broader shift in nutritional science towards proactive, health-oriented dietary strategies. This article provides a comprehensive, interdisciplinary overview of functional foods by examining their biological mechanisms, clinical evidence, public health significance, regulatory frameworks, and future prospects—particularly in the context of advances in personalized nutrition and nutrigenomics. A thorough literature review was conducted, drawing from recent peer-reviewed studies and guidelines from key health authorities. The review highlights the roles of specific compounds such as probiotics and prebiotics in modulating the gut microbiome, flavonoids and polyphenols in anti-inflammatory processes, omega-3 fatty acids in cardiometabolic regulation, and vitamins and minerals in supporting immune function. While an expanding body of clinical trials and meta-analyses supports the health benefits of these compounds—including reductions in LDL cholesterol, improved insulin sensitivity, and mitigation of oxidative stress—the integration of functional foods into everyday diets remains challenging. Socioeconomic disparities and limited health literacy often impede their accessibility and widespread adoption in public health practice. Functional foods represent a promising component of prevention-focused modern healthcare. To maximize their impact, a coordinated, evidence-based approach is essential, involving collaboration among healthcare professionals, nutrition scientists, policymakers, and the food industry. Looking forward, innovations in artificial intelligence, microbiome research, and genomic technologies may unlock novel opportunities for the targeted and effective application of functional foods in population health.

Pea and lentil flours are added to baked foods, pastas, and snacks to improve nutritional quality and functionality compared to products made solely with refined wheat flour. However, the effect of whole pulses versus their serving size equivalent of flour on blood glucose has not been investigated in persons with altered glycemic response. Health claims for whole pulses are based on a ½ cup amount whereas commercial pulse flour servings are typically a smaller size. The glycemic responses of four treatment meals containing 50 g available carbohydrate as ½ cup whole pulse or the dry weight equivalent of pulse flour were compared with a control beverage (Glucola^®). Eleven adults with type 2 diabetes mellitus (T2DM) and eight adults with metabolic syndrome (MetS) completed the study. Venous blood samples were collected at fasting and at 30 min intervals postprandial for three hours. Changes in net difference in plasma glucose over time from baseline and incremental area under the curve (iAUC) segments were analyzed. All four pulse meals attenuated the iAUC compared to the control from 0 to 120 min for T2DM participants and 0–180 min for MetS participants. Whole pulses produced a lower glycemic response than pulse flours in the early postprandial period for persons with T2DM and during the overall test period for those with MetS. Full article

Introduction: Olive oil’s health benefits are widely known and extensively documented; its advantages are widespread, covering numerous areas of human health. Clinical and experimental data indicate that a Mediterranean Diet (MedDiet) with Extra Virgin Olive Oil (EVOO) lowers the risk of illnesses associated with oxidative stress, chronic inflammation, and weakened immunity, including cancer and cardiovascular disease (CVD). The European Food Safety Authority (EFSA) confirms that olive oil’s polyphenols help protect blood lipids against oxidative damage; thus, EVOO, crucial in the MedDiet, could be a functional food component. Olive oils must contain at least 5 mg of Hydroxytyrosol (HYTY) and its derivatives (oleuropein and Tyrosol (TY)) per 20 g to qualify for the EFSA-approved health claim. To provide a summary of clinical study results, this systematic review assessed the impact of Virgin olive oil (VOO) consumption on cardiovascular risk and disease prevention. Methods: The systematic review’s studies were collected from PubMed, Cochrane, Web of Science, and Scopus following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and the Population Intervention Comparison Outcome Population (PICO) framework. Results: Seventeen clinical studies were identified, which highlighted the association between VOO consumption (including EVOO) and a reduced risk of cardiovascular disease. Particularly, improvements in biomarkers involved in cardiometabolic pathways and subsequent cardiovascular events were recorded. The beneficial effect was attributed to the polyphenols contained in EVOO. Indeed, EVOO supplementation as part of the Mediterranean diet could improve patients’ quality of life in secondary prevention by demonstrating a positive correlation with the cardioprotective role of polyphenols. Discussion: A balanced diet with VOO represents a simple yet potent method to counteract metabolic dysfunctions associated with CVD. Despite these results, further multicenter clinical studies with a wider range of patients are required to confirm and better understand EVOO’s effects on the prevention of cardiovascular risk.

Background/Objective: Type 2 diabetes mellitus (T2D) is a chronic metabolic disorder characterized by hyperglycemia. Plant-based interventions have gained attention as potential complementary treatments alongside conventional therapies. This systematic review evaluates the efficacy of plant-based interventions in improving glycemic control, insulin sensitivity, lipid profiles, and other outcomes such as GLUT-4, Tumor Necrosis Facto-alpha, dietary inflammation index, plasma lipopolysaccharide, total antioxidant capacity, and malondialdehyde in individuals with T2D. Methods: We conducted a systematic search of PubMed, Scopus, and ScienceDirect databases to identify randomized controlled trials (RCTs) and observational studies. RCTs were used as an additional screening criterion. The review included studies on the effects of plant-based interventions, encompassing fruits, vegetables, herbs, spices, and their extracts. We analyzed data on glycemic control, insulin sensitivity, lipid profiles, and other metabolic markers. Results: Twenty-six studies were included in our analysis. Various interventions showed potential benefits, with improved glycemic control, insulin sensitivity, and lipid profiles. Specific interventions such as Ziziphus jujuba juice, black tea, caper fruit extract, and balanced diets were linked with positive outcomes. Based on the Functional Food Claim framework, all 26 studies met the quality criteria for novel foods. However, the novel food score varied, and results were inconsistent across different interventions. Conclusion: Although some plant-based interventions appear promising in managing T2D, the evidence remains inconclusive due to variability in study quality and methodology. Further high-quality RCTs are necessary to confirm these findings and to establish the optimal dosage, duration, and combinations of interventions for effective T2D management. Despite inconclusive results, few plant-based diets have promising outcomes. Healthcare providers, especially nurse case managers, can incorporate the findings of this study into their practice protocol to support self-management for individuals with TD2. Full article

Amid the global rise in chronic diseases and escalating costs, functional foods have become a preventive solution, offering benefits beyond essential nutrition. However, the regulatory landscape remains complex, requiring a balance between consumer protection and industry innovation. Previous studies seldom examine how markets and regulation evolve, leaving a clear gap that this review addresses. This study aims to propose a framework focusing on the risk side (quality and safety) and benefit side (functionality) to analyze functional food regulations, and to examine the evolution of regulatory systems and their impact on industry development through a historical analysis of Japan’s functional food regulation from the 1960s. The results reveal that regulations have co-evolved with industry growth, dynamically balancing the risk and benefit sides. Milestones, such as the introduction of the Foods with Function Claims (FFC) system and the Beni-koji (red yeast rice) contamination incident in 2024, highlight adjustments in this balance. The findings suggest that the risk-/benefit-side framework provides a valuable lens for understanding the interplay between regulation and innovation in the functional food industry. This study contributes to regulatory science by offering empirical evidence from the sector and has practical implications for policymakers seeking to design frameworks that promote both innovation and consumer welfare.

The growing demand for healthier meat products has driven the reformulation of processed meats to reduce saturated fat while preserving sensory and technological attributes. Buffalo meat (Bubalus bubalis), with its high protein content, low intramuscular fat, and favorable fatty acid profile, offers a promising base for healthier formulations. However, its fat content may compromise texture, juiciness, and flavor, necessitating strategies to optimize product quality. This study investigated the effects of replacing pork fat with inulin and pumpkin seed oil in a cooked buffalo meat product, focusing on compositional, oxidative, microbiological, and sensory parameters. Two plant-based ingredients were selected: inulin from chicory, used as a fat mimic due to its gel-forming ability, and pumpkin seed oil, a structural analog with antimicrobial activity. Preliminary trials identified optimal concentrations for balancing technological and functional performance. A 2% inclusion of pumpkin seed oil, exceeding its in vitro MIC (0.4–1.5%), ensured effectiveness in the food matrix. Reformulated products exhibited significantly reduced fat (p < 0.05), enhanced fiber, and a lipid profile rich in polyunsaturated fatty acids (>45%), qualifying for European Union health claims. Oxidative stability improved (p < 0.01), and sensory analysis revealed enhanced aroma complexity, with nutty and roasted notes. Microbiological assessments confirmed a protective effect against spoilage bacteria. These results support the development of a nutritionally improved, microbiologically safer cooked product, such as mortadella-style sausage, while also offering strategies for broader innovation in reformulating functional meat products.

The characteristics of bioactive compounds from guava (Psidium guajava L.) leaf extract, their biological activity, and their technological applications are critical topics in many engineering fields. Guava leaf extract is rich in bioactive compounds, including phenolic acids, flavonoids, tannins, terpenes, alkaloids, etc. Bioactive compounds from guava leaf exhibit notable synergistic effects in enzyme inhibition, as well as antimicrobial and anti-inflammatory activities. Natural bioactive compounds are complicated due to their sensitivity and instability during storage, but their use is promising. Thus, for bioactive compound protection, advanced techniques such as the encapsulation, microemulsion, and nanosuspension of such natural bioactive compounds can be a promising approach. These methods are particularly important for the development of natural preservatives serving as additive agents, which have significant industrial relevance. However, sufficient scientific evidence is required to make a health claim on and to promote the functional benefits of guava leaf extract. This review focuses on recent research into guava leaf extract and its technical roles. Demonstrations of the chemical structure of bioactive compounds are addressed, besides discussing their analytical methods, nutritional bioavailability, biological activity, and synergy effects. Furthermore, this review study considers the methods used to protect the active compounds and technological applications in food, pharmaceuticals, and cosmetic products. Full article

Pasta made from durum wheat semolina has a medium–high glycemic index score, high starch digestibility, and limited nutritional value due to its low fiber, vitamin, and bioactive compound content. This study aimed to enhance pasta’s nutritional and functional qualities by incorporating Pleurotus eryngii (PE) powder at various substitution levels to achieve one nutritional claim at least. This research involved two phases: evaluating the chemical/physical, nutritional, functional, and sensory properties of laboratory-scale samples and validating the selected formulations through industrial-scale production and shelf-life analyses. The pasta sample with 8.62% PE substitution (SPE8-P) demonstrated significantly improved nutritional qualities, including high fiber content sufficient for a “high fiber content” claim, and potential prebiotic activity indicated by increased bifidobacterial density during simulated fecal microbiota fermentation. Despite its enhanced riboflavin and antioxidant content, regulatory constraints limited the inclusion of claims for vitamin B2 richness and antioxidant activity. Although significantly affecting the color, taste, and odor profiles, the sensory analysis revealed high overall acceptability, supporting the product’s potential for consumer acceptance. This study confirms the feasibility of producing innovative, nutritionally enriched pasta with PE powder as a functional ingredient. Future research will focus on in vivo evaluation to establish the potential for classifying this pasta prototype as a functional food. Full article

Lactic acid bacteria (LAB) exopolysaccharides (EPSs) have garnered significant scientific interest due to their multifaceted roles in food technology and health promotion. This comprehensive review systematically examines the structural classification of LAB EPSs, emphasizing distinctions between homo-and heteropolysaccharides, as well as the influence of substituent groups (e. g., acetyl, phosphate) on their physicochemical and bioactive properties. Advanced isolation methodologies, including ethanol precipitation and ultrafiltration, coupled with characterization techniques such as nuclear magnetic resonance (NMR) spectroscopy and atomic force microscopy (AFM), are vital for deciphering their chemical and physical characteristics. The biosynthesis pathway, governed by eps operons and modulated by environmental factors (e.g., carbon sources, Ca²⁺), are discussed as targets for genetic engineering to enhance yield and functionality. Functionally, LAB EPSs display antioxidant, immunomodulatory, anti-tumor, anti-viral, and anti-biofilm activities, with demonstrated applications as natural additives in the food industry, prebiotics, and drug delivery systems. Despite their potential, challenges such as cost-effective production and regulatory hurdles persist. Future research should prioritize the elucidation of molecular mechanisms, clinical validation of health claims, and sustainable bioprocessing innovations to fully harness the transformative potential of LAB EPSs across food, pharmaceutical, and agricultural industries.

The current study examines the impact of health claims on consumer preferences and willingness to pay (WTP) for functional snack bars, focusing on anti-inflammatory and antioxidant properties. Through an experimental auction involving 175 participants, this study investigates how providing clear information on product health benefits influences consumer interest and WTP while analysing the role of individual health consciousness (HC) in shaping these preferences. The results indicate that detailed health claims positively affect consumer WTP for functional snack bars compared to standard options. Although both anti-inflammatory and antioxidant claims attract consumer interest, no significant difference in WTP was observed between the two, suggesting similar perceived value for these distinct benefits. However, highly health-conscious consumers demonstrate a stronger preference and WTP for anti-inflammatory options, indicating that HC influences specific health claim valuation. These findings underscore the importance of effective health-related messaging in promoting functional foods and suggest that general health claims may resonate more broadly with consumers than specialised ones. This study’s results enhance the current knowledge on functional foods, especially snack bars, offering valuable insights for manufacturers aiming to implement targeted marketing strategies and public health initiatives focused on promoting healthier dietary choices.

Aligning with sustainable green practices, this study examines the partial replacement of chickpea protein isolate with commercially available autotrophic Chlorella vulgaris (Auto-Chlorella) and heterotrophic Parachlorella kessleri (Hetero-Chlorella) to assess impacts on food emulsions’ properties and potential functional value. Rheology and texture analysis show that Chlorella biocompounds enhance emulsions by creating a synergistic network with chickpea proteins. The type of Chlorella used significantly influences emulsion characteristics due to differences in culture and processing conditions. Hetero-Chlorella contributed to more structured emulsions, revealed by higher values of the viscoelastic functions (G′, G″, and G⁰_N), indicating a complex three-dimensional network (p < 0.05), while Auto-Chlorella excelled in augmenting dietary elements (p < 0.05), leading to emulsions rich in antioxidants and allowing for a ’rich in iron’ claim. Both types contribute to smaller oil droplet size, improved firmness, adhesiveness, and appealing coloration (p < 0.05). Preliminary findings on Vitamin B12 content suggest promising bioavailability potential. However, the nutritional density of Chlorella emphasizes the need for careful microbiological stability. Produced on a lab scale without preservatives, these emulsions highlight the need for preservation strategies in large-scale production. This research supports the potential for industrial microalgae-based mayonnaise, addressing consumer demand for innovation while prioritizing safety. Full article

Neurodegenerative diseases such as Alzheimer’s disease (AD), Parkinson’s disease (PD), amyotrophic lateral sclerosis (ALS), and multiple sclerosis (MS), which are a consequence of the progressive loss of neuronal function and structure, cause significant cognitive impairment. The incidence of these diseases in the world’s population is constantly increasing as a result of an aging population. Although genetic and environmental factors are most often mentioned as the pathogenetic factors of these diseases, increasing evidence points to the important role of proper nutrition in the prevention and support of the treatment of these disorders. A healthy, balanced diet can mitigate the risks associated with the risk factors mentioned above and slow the progression of the disease by reducing oxidative stress and inflammation. Vitamins B, D, E, C, K, and A have been shown to support cognitive functions and protect the nervous system. This review demonstrates the importance of vitamins in preventing and supporting the therapy of neurodegenerative diseases. Information regarding the health-promoting properties of these vitamins must be effectively communicated to consumers seeking to protect their health, particularly in the context of neurodegenerative diseases. Consequently, this review also examines the authorized health claims under EU food law related to these vitamins, assessing their role in promoting awareness of the vitamins’ potential benefits for neuroprotection and the management of neurodegenerative diseases.
