Black Trumpet [Craterellus cornucopioides (L.) Pers.]-Bioactive Properties and Prospects for Application in Medicine and Production of Health-Promoting Food.

Black trumpet (Craterellus cornucopioides) is a mushroom present in many countries but underestimated. The aim of this publication is to present the latest state of knowledge about the chemical composition and bioactivity of C. cornucopioides and the possibility of its application in food. According to researchers, black trumpet is very rich in nutritional compounds, including unsaturated fatty acids (mainly oleic and linoleic acids), ß-glucans, minerals, and vitamins as well as polyphenols and tannins. It also contains compounds influencing the sensory properties, like free amino acids and nucleotides as well as sugars and polyols, mainly mannitol. Many of the described components show high nutritional and bioactive properties. Therefore, C. cornucopioides shows antioxidant activity and immunostimulating, anti-inflammatory, and anticancer effects as well as antibacterial, antifungal, antiviral, and antihyperglycemic effects. This makes black trumpet, also called horn of plenty, a mushroom with great potential for use both in medicine and directly in food. So far, black trumpet is not widely used in food, especially processed food. There are only a few studies on the use of dried black trumpet in sausages, but there is great potential for its use in food.

Genomic Characterization and Safety Assessment of Bifidobacterium breve BS2-PB3 as Functional Food.

Our group had isolated Bifidobacterium breve strain BS2-PB3 from human breast milk. In this study, we sequenced the whole genome of B. breve BS2-PB3, and with a focus on its safety profile, various probiotic characteristics (presence of antibiotic resistance genes, virulence factors, and mobile elements) were then determined through bioinformatic analyses. The antibiotic resistance profile of B. breve BS2-PB3 was also evaluated. The whole genome of B. breve BS2-PB3 consisted of 2,268,931 base pairs with a G-C content of 58.89% and 2,108 coding regions. The average nucleotide identity and whole-genome phylogenetic analyses supported the classification of B. breve BS2-PB3. According to our in silico assessment, B. breve BS2-PB3 possesses antioxidant and immunomodulation properties in addition to various genes related to the probiotic properties of heat, cold, and acid stress, bile tolerance, and adhesion. Antibiotic susceptibility was evaluated using the Kirby-Bauer disk-diffusion test, in which the minimum inhibitory concentrations for selected antibiotics were subsequently tested using the Epsilometer test. B. breve BS2-PB3 only exhibited selected resistance phenotypes, i.e., to mupirocin (minimum inhibitory concentration/MIC >1,024 µg/ml), sulfamethoxazole (MIC >1,024 µg/ml), and oxacillin (MIC >3 µg/ml). The resistance genes against those antibiotics, i.e., ileS, mupB, sul4, mecC and ramA, were detected within its genome as well. While no virulence factor was detected, four insertion sequences were identified within the genome but were located away from the identified antibiotic resistance genes. In conclusion, B. breve BS2-PB3 demonstrated a sufficient safety profile, making it a promising candidate for further development as a potential functional food.

Current perspectives on fenugreek bioactive compounds and their potential impact on human health: A review of recent insights into functional foods and other high value applications.

Despite long-standing uses in several food and medicine traditions, the full potential of the leguminous crop fenugreek (Trigonella foenum-graecum L.) remains to be realized in the modern diet. Not only its seeds, which are highly prized for their culinary and medicinal properties, but also its leaves and stems abound in phytochemicals with high nutritional and health promoting attributes. Fenugreek dual food-medicine applications and reported metabolic activities include hypoglycemic, antihyperlipidemic, antioxidative, anti-inflammatory, antiatherogenic, antihypertensive, anticarcinogenic, immunomodulatory, and antinociceptive effects, with potential organ-protective effects at the cardiovascular, digestive, hepatic, endocrine, and central nervous system levels. Effectiveness in alleviating certain inflammatory skin conditions and dysfunctions of the reproductive system was also suggested. As a food ingredient, fenugreek can enhance the sensory, nutritional, and nutraceutical qualities of a wide variety of foods. Its high nutritive density can assist with the design of dietary items that meet the demand for novelty, variety, and healthier foods. Its seeds provide essential protective nutrients and other bioactive compounds, notably galactomannans, flavonoids, coumarins, saponins, alkaloids, and essential oils, whose health benefits, alone or in conjunction with other bioactives, are only beginning to be tapped into in the food industries. This review summarizes the current state of evidence on fenugreek potential for functional food development, focusing on the nutrients and non-nutrient bioactive components of interest from a dietary perspective, and their applications for enhancing the functional and nutraceutical value of foods and beverages. New developments, safety, clinical evidence, presumed mechanisms of action, and future perspectives are discussed. HIGHLIGHTS: Fenugreek seeds and leaves have long-standing uses in the food-medicine continuum. Fenugreek phytochemicals exert broad-spectrum biological and pharmacological activities. They show high preventive and nutraceutical potential against common chronic diseases. Current evidence supports multiple mechanisms of action mediated by distinct bioactives. Opportunities for fenugreek-based functional foods and nutraceuticals are expanding.

Indigenous spices consumed in the food habits of the populations living in some countries of Sub-Saharan Africa: Utilisation value, nutritional and health potentials for the development of functional foods and drugs: A review.

This manuscript reviews the literature by giving a brief history of spices in general, how they played an important role in the past for the discovery of the world. The review paper gives the value of spices today then makes a difference between the group of spices on which it is focused (local, indigenous, less-known or under-utilised spices) and the conventional spices. The utilisation value of the spices by the populations is discussed as ethno-nutritional and ethnopharmacological uses, and scientific evidences from laboratory experimentations are reviewed to support some ethnopharmacological claims that are made on this plant materials, as well as their physicochemical composition. The review shows that less-known and under-utilised spices consumed in the food habits of population groups living in some Sub-Saharan African countries constitute an industrial opportunity for the development of modern food products, nutraceuticals and functional foods.

Assessment of the Impact of Scientific Reports Published by EFSA and GIS on Functional Foods Newly Placed on the Market in Poland.

Dietary supplements are health-promoting products. The legal categorization of dietary supplements as foods does not raise concerns, but a general understanding of how they work in the human body seems to deviate from the official definition. Thus, it is necessary to establish effective methods of market control related to dietary supplements. This research aims at assessing the impact of recommendations by various food safety authorities on ingredients used in newly registered products. It probes how the proportions of utilized product ingredients were modified after the European Food Safety Authority (EFSA) and Chief Sanitary Inspector in Poland (GIS) published their recommendations. Research data on the composition of products comes from the Polish national register of dietary supplements and covers the period from 2012 to 28 November 2021. Note that 103,102 products were analysed for the presence of thirty-seven ingredients, and the joinpoint regression method was applied to assess changing trends related to the use of ingredients. As our research points out, most often, changes in the trend appeared in product ingredients for which the European Food Safety Authority and Chief Sanitary Inspector in Poland issued the recommendation of having the safest level of consumption. However, these changes seem to emerge randomly and should not be unquestionably considered as the result of the published recommendations.

Assessment of Potential Benefits of Functional Food Characteristics of Beetroot Energy Drink and Flavored Milk.

Objective: This study was designed to determine the antioxidant activity of the extracts of beetroot by using beetroot energy drink and flavored milk (products). Material & Methods. This experimental trial was conducted at Jinnah University for Women, Pakistan, under the approval of local institutional review board number JUW/DFST/RCB010/2020. All the materials such as beetroot, carrot, cucumber, and lemon were obtained commercially from which two products were formulated: beetroot energy drink (sample1) and flavored milk (sample 2). These formulated products were evaluated for quality analysis (pH and brix), phytochemical screening using the Keller-Kiliani test, Salkowski's test, Alkaline reagent test, lead acetate test, ferric chloride test, protein test, quantitative test of phenol, antioxidant activity, sensory analysis, and shelf life study. The paired t-test was applied to detect significant differences between two samples. Results: The phytochemical analysis revealed that cardiac glycosides, phytosterol, flavonoids, and terpenoids were found in both energy booster drink (EBD) and flavored milk (FM) except phenolic compounds that were found only in EBD. The antioxidant capacity of beetroot juice was far greater than FM. The statistical sensorial analysis of FM and EBD reported a significant mean difference between most of the groups with p < 0.0001. Conclusion: This study concludes that energy drinks having beetroot indicated higher antioxidant capacity than flavored milk. The nutraceutical products (energy booster drink and flavored milk) containing beetroot are enriched with optimum quantities of proteins and fats and low carbohydrates at a stable pH with an adequate total energy content.

In vivo Toxicity Assessment of Refined Red Palm-pressed Mesocarp Olein in Sprague-Dawley Rats.

Refined red palm-pressed mesocarp olein (PPMO) is recovered from palm-pressed mesocarp fiber, which is a by-product from palm oil mill. Its utilization in food industry is extremely limited even though it contains various phytonutrients. Thus, this study aimed to evaluate its toxicity effects by using the male Sprague-Dawley rat model. The rats were administered with a single dose of 2 g/kg PPMO in an acute toxicity study while administered with 2, 1, or 0.5 g/kg PPMO daily for 28 days in a sub-chronic toxicity study. The mortality, oral LD50 value, clinical observation, body and organ weight, hematological and biochemical analyses, pathological and histopathological examinations were assessed. The overall outcomes indicated that PPMO is non-toxic up to 2 g/kg and considered safe to be used in food application, especially as functional food ingredient and supplement attributed to its phytonutrients. Besides, this study provides an insight in alternative utilization of the wastes from palm oil mill.

Understanding the role of information and taste heterogeneity in consumer preferences for functional beef: The case of the omega-3 enriched burger.

Beef demand has progressively decreased due to an increasing number of consumers who perceive beef as harmful to their health, among other causes. In contrast, functional foods are one of the fastest-growing markets. This study aims to analyse consumer preferences and estimates the willingness to pay for beef enriched with omega-3 fatty acids. We intend to identify and profile the potential market segments for functional beef and determine how the provision of information can affect consumer preferences. Data have been collected by applying a choice experiment on a sample of 757 Italian beef purchasers. The sample was randomly split into two information treatments plus a control group. Participants in the information treatments were given an explanation about the functional meat production system. Results showed that the average consumer has a preference for ω-3 enrichment and that information about the food's production process increases this preference. Therefore, the study reveals the existence of a potentially profitable market for functional beef.

[A Basis for Pharmaceutical Sciences "Quality Assurance": Quality Assurance of Health Foods, Foods with Health Claims, and Pharmaceutics].

The author believes that the three pillars of pharmaceutical sciences (PS) in Japan are drug development science, medical pharmacy, and quality management science. Of these, the most PS-like science is quality management science, both historically and presently. Considering the balance of safety and efficacy is the basis of PS. The definition of "quality" is the degree to which a set of inherent properties of a product, system, or process fulfills requirements in Q9 of International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH). In our society, pharmaceutical science graduates including pharmacists, are active participants, not only in the pharmaceutical industry, including a pharmacy, but also in the food industry, especially for quality assurance and quality control. This report presents a focused overview of quality in health foods, foods with health claims, and pharmaceutical products and discusses the importance of a curriculum focusing on quality assurance, control, and management in pharmaceutical education.

Effects of Thai Local Ingredient Odorants, Litsea cubeba and Garlic Essential Oils, on Brainwaves and Moods.

The functional food market is growing with a compound annual growth rate of 7.9%. Thai food recipes use several kinds of herbs. Lemongrass, garlic, and turmeric are ingredients used in Thai curry paste. Essential oils released in the preparation step create the flavor and fragrance of the famous tom yum and massaman dishes. While the biological activities of these ingredients have been investigated, including the antioxidant, anti-inflammatory, and antimicrobial activities, there is still a lack of understanding regarding the responses to the essential oils of these plants. To investigate the effects of essential oil inhalation on the brain and mood responses, electroencephalography was carried out during the non-task resting state, and self-assessment of the mood state was performed. The essential oils were prepared in several dilutions in the range of the supra-threshold level. The results show that Litsea cubeba oil inhalation showed a sedative effect, observed from alpha and beta wave power reductions. The frontal and temporal regions of the brain were involved in the wave alterations. Garlic oil increased the alpha wave power at lower concentrations; however, a sedative effect was also observed at higher concentrations. Lower dilution oil induced changes in the fast alpha activity in the frontal region. The alpha and beta wave powers were decreased with higher dilution oils, particularly in the temporal, parietal, and occipital regions. Both Litsea cubeba and turmeric oils resulted in better positive moods than garlic oil. Garlic oil caused more negative moods than the others. The psychophysiological activities and the related brain functions require further investigation. The knowledge obtained from this study may be used to design functional food products.

Colloidal gold-based lateral flow immunoassay with inline cleanup for rapid on-site screening of carbendazim in functional foods.

In this study, for the first time, we propose a sensitive colloidal gold-based lateral flow immunoassay (LFIA) that can be used to detect carbendazim residues in functional foods. The adoption of inline cleanup LFIA strips effectively improved background interference to reduce misjudgment of results. First, the hapten 2-(methylamino)-1H-benzo[d]imidazole-5-carboxylic acid was used to establish the carbendazim immunoassay method. Subsequently, colloidal gold-mAb preparation and LFIA detection conditions were systematically optimized. For root and fruit samples (ginseng, ginger, jujube, and Chinese wolfberry), the designed strips had a cutoff value of 8 ng/mL. For flower and seed samples (chrysanthemum, coix seed, and malt), the cutoff value was 12 ng/mL. Even in a complex matrix, the established LFIA method demonstrates satisfactory sensitivity and anti-interference ability. This method was successfully applied in detection of carbendazim residues in complex functional foods, and the assay results are consistent with those obtained via liquid chromatography-tandem mass spectrometry. In short, the proposed method is fast and sensitive and has strong anti-interference ability. Furthermore, it provides a new technical method highly relevant to the on-site rapid detection of carbendazim residues in complex sample matrix.

Trp-Trp acts as a multifunctional blocker for human bitter taste receptors, hTAS2R14, hTAS2R16, hTAS2R43, and hTAS2R46.

Many functional food ingredients activate human bitter taste receptors (hTAS2Rs). In this study, A novel inhibitor, Trp-Trp, for hTAS2R14 was identified by searching for the agonist peptide's analogs. Trp-Trp also inhibited hTAS2R16, hTAS2R43, and hTAS2R46, which share the same agonists with hTAS2R14. The multifunctional characteristic of Trp-Trp is advantageous for use as bitterness-masking agents in functional foods.

[Considerations of Providing the Public with Health Information].

Nowadays, approximately 90 percent of the general population in Japan uses the internet and many of them look for health-related information. However, there have been serious concerns about the contents and credibility of these information. Among "mixture of wheat and chaff", information provided by the public domains are expected as accurate and reliable ones. This article reviews five public websites that provide health or health care information for users including the general population: Minds by the Japan Council for Quality Health Care, e-health net, evidence-based Japanese Integrative Medicine (eJIM), Cancer Information Service by the National Cancer Center, Center for Cancer Control and Information Services, Information system on safety and effectiveness for health foods (HF net) by National Institute of Health and Nutrition. These websites show their running policy transparently and have constructed collaborative relationships with each domain experts, and from the people who are not related with the healthcare field including patients in some cases. Each of them is content-rich and well-organized as an individual unit. The organizations that run these websites share the common goal that provides the general population with quality health-related information, however, cooperation have been limited. To increase awareness among the public, it is worthy considering joint efforts of these organizations in future.

Alimentos funcionais: percepção dos consumidores no Distrito Federal, Brasil / 099Functional foods: consumer perception in the Federal District, Brazil

Os alimentos funcionais fazem parte de uma nova concepção de alimentos, que quando consumido junto com uma dieta saudável, equilibrada e usual, promovem benefícios à saúde. Entretanto, a divulgação de informações sobre alimentos funcionais através de órgãos governamentais, científicas, mercadológicas, entre outros, tem levado os consumidores a interpretações distintas sobre esse alimento. O objetivo deste estudo foi analisar como os consumidores do Distrito Federal, Brasil, estão interpretando as informações, efeitos e riscos dos alimentos funcionais na saúde. Foi realizada uma pesquisa com 111 respondentes, utilizado survey, com roteiro de entrevista estruturado para a coleta de dados. As questões do roteiro passaram por validação semântica, conteúdo e estatística e os constructos (confiança, medicamento, mídia, necessidade, recompensa e risco) foram avaliados pelos consumidores através da escala Likert de sete pontos. Os consumidores acreditam no efeito benéfico que os alimentos funcionais podem proporcionar à saúde, e os veem como efeito de cura ou de prevenção de doenças. O processo de divulgação de informações sobre os alimentos funcionais deve ser reavaliado em todas as instâncias, governamentais e mercadológicas, para que as informações sejam mais claras e entendíveis para todos. Os relacionamentos entre as variáveis socioeconômicas foram analisados por testes de Qui-quadrado e a percepção de consumidores de alimentos funcionais através do coeficiente de correlação de Pearson. Os testes Qui-quadrado indicaram associações altamente significativas (p<0,001) entre as variáveis estado civil e principal comprador de comida em casa e entre nível de escolaridade e renda familiar. O constructo medicamento foi o único que apresentou relação significativa com todos os demais.(AU)

Functional foods are part of a new concept of food, which when consumed together with a healthy, balanced and usual diet, promote health benefits. However, the dissemination of information on functional foods through governmental, scientific, and marketing agencies, among others, has led consumers to different interpretations of this food. The aim of this study was to analyze how consumers in the Federal District, Brazil, are interpreting the information, effects, and risks of functional foods on health. A survey was carried out with 111 respondents, containing a structured interview script for data collection. The questions in the script went through validation of semantics, content, and statistics, and the constructs (trust, medication, media, need, reward, and risk) were assessed by consumers using a seven-point Likert scale. Consumers believe in the beneficial effect that functional foods can have on health, and see it as a cure or disease prevention effect. The process of disclosing information about functional foods should be reevaluated at all levels, both governmental and commercial, so that the information is clearer and understandable for everyone. The relationships between socioeconomic variables were analyzed using Chi-squared tests and the consumers’ perception of functional foods through Pearson's correlation coefficient. The Chi-squared tests indicated highly significant associations (p<0.001) between the variables marital status and being the main buyer of food at home, and between level of education and family income. The medication construct was the only one that showed a significant relationship with all the other dimensions.(AU)

Carotenoids: Considerations for Their Use in Functional Foods, Nutraceuticals, Nutricosmetics, Supplements, Botanicals, and Novel Foods in the Context of Sustainability, Circular Economy, and Climate Change.

Research on carotenoids in agro-food and health is being propelled by the two multidisciplinary international networks, the Ibero-American Network for the Study of Carotenoids as Functional Foods Ingredients (IBERCAROT; http://www.cyted.org) and the European Network to Advance Carotenoid Research and Applications in Agro-Food and Health (EUROCAROTEN; http://www.eurocaroten.eu). In this review, considerations for their safe and sustainable use in products mostly intended for health promotion are provided. Specifically, information about sources, intakes, and factors affecting bioavailability is summarized. Furthermore, their health-promoting actions and importance in public health in relation to the contribution of reducing the risk of diverse ailments are synthesized. Definitions and regulatory and safety information for carotenoid-containing products are provided. Lastly, recent trends in research in the context of sustainable healthy diets are summarized.

Assessment of chemical composition and antioxidant properties of defatted flours obtained from several edible insects.

The aims of this study were determined the chemical composition and the antioxidant properties of defatted flours obtained from several commercially available edible insects such as Acheta dosmesticus, Tenebrio molitor, Zophobas morio, and Rhynchophorus ferrugineus to establish their utilization as ingredient in the development of new food products. The proximate composition of flour was determined using AOAC methods while for antioxidant capacity, four different methodologies were employed (DPPH, ABTS, FIC, and FRAP). The total phenolic content and the tannin content were also determined. All flours analyzed had a high protein content with values ranging between 64.17 and 72.55 g/100 g flour. With regard to the antioxidant activity, R. ferrugineus showed the highest values for DPPH, ABTS, and FRAP assays with values of 2.03, 4.93, and 8.46 mg Trolox equivalent/g flour, respectively. For FIC assay, A. dosmesticus and T. molitor had the highest values 0.47 and 0.48 mg EDTA equivalent/g flour. Defatted flours obtained from edible insects analyzed could have several applications as ingredients to the development new foods due to its good nutrient content and as a functional food for the prevention of oxidation.

Health-promoting activities of edible seaweed extracts from Chilean coasts: assessment of antioxidant, anti-diabetic, anti-inflammatory and antimicrobial potential / Actividades promotoras de la salud de extractos de algas comestibles de las costas chilenas: evaluación del potencial antioxidante, antidiabético, antiinflamatorio y antimicrobiano

ABSTRACT The aim of this study was to evaluate the antioxidant, antidiabetic, anti-inflammatory and antimicrobial activities of three edible seaweed extracts from Chilean coasts: Pyropia orbicularis, Ulva spp, and Durvillaea antarctica. Seaweed extracts in methanol and 70% acetone were performed to evaluate antioxidant and antidiabetic activities, whereas 60% methanol was used to measure anti-inflammatory and antimicrobial activities. Acetone extracts from D. antarctica had the highest total phenolic content and consequently exhibited the strongest antioxidant activity, while methanol extract of this seaweed presented the highest α-glucosidase inhibition (IC50= 0.004 mg mL-1). In the tests against E. coli and Penicillium sp., the extracts obtained from Ulva spp. were the most effective and exhibited the maximum anti-inflammatory effect against phorbol 12-myristate 13-acetate irritant agent (61.8% inhibition) in mice. Results indicated that all evaluated Chilean seaweed extracts are promising candidates for application in functional foods and in the pharmaceutical industry.

RESUMEN El objetivo de este estudio fue evaluar las actividades antioxidantes, antidiabéticas, antiinflamatorias y antimicrobianas de los extractos de tres algas marinas comestibles de las costas Chilenas (Pyropia orbicularis, Ulva spp. y Durvillaea antarctica). Se realizaron extractos de algas marinas en metanol y acetona al 70% para evaluar las actividades antioxidantes y antidiabéticas, mientras que el metanol al 60% se usó para actividades antiinflamatorias y antimicrobianas. Los extractos de acetona de D. antarctica tuvieron el mayor contenido de fenoles totales (TPC) y, en consecuencia, exhibieron la mayor actividad antioxidante, mientras que el extracto metanólico de estas algas presentó la mayor inhibición de la α-glucosidasa (IC50= 0,004 mg mL-1). En las pruebas contra E. coli y Penicillium sp., los extractos obtenidos de Ulva spp., actuaron como los más efectivos y exhibieron el máximo efecto antiinflamatorio contra el agente irritante de forbol 12-miristato 13-acetato (TPA) (inhibición del 61,8%) en ratones. Por lo tanto, los resultados indican que todos los extractos de algas chilenas evaluados pueden ser candidatos prometedores para su aplicación en alimentos funcionales y en las industrias farmacéuticas.

Postbiotics-parabiotics: the new horizons in microbial biotherapy and functional foods.

Probiotics have several health benefits by modulating gut microbiome; however, techno-functional limitations such as viability controls have hampered their full potential applications in the food and pharmaceutical sectors. Therefore, the focus is gradually shifting from viable probiotic bacteria towards non-viable paraprobiotics and/or probiotics derived biomolecules, so-called postbiotics. Paraprobiotics and postbiotics are the emerging concepts in the functional foods field because they impart an array of health-promoting properties. Although, these terms are not well defined, however, for time being these terms have been defined as here. The postbiotics are the complex mixture of metabolic products secreted by probiotics in cell-free supernatants such as enzymes, secreted proteins, short chain fatty acids, vitamins, secreted biosurfactants, amino acids, peptides, organic acids, etc. While, the paraprobiotics are the inactivated microbial cells of probiotics (intact or ruptured containing cell components such as peptidoglycans, teichoic acids, surface proteins, etc.) or crude cell extracts (i.e. with complex chemical composition)". However, in many instances postbiotics have been used for whole category of postbiotics and parabiotics. These elicit several advantages over probiotics like; (i) availability in their pure form, (ii) ease in production and storage, (iii) availability of production process for industrial-scale-up, (iv) specific mechanism of action, (v) better accessibility of Microbes Associated Molecular Pattern (MAMP) during recognition and interaction with Pattern Recognition Receptors (PRR) and (vi) more likely to trigger only the targeted responses by specific ligand-receptor interactions. The current review comprehensively summarizes and discussed various methodologies implied to extract, purify, and identification of paraprobiotic and postbiotic compounds and their potential health benefits.

The position of functional foods and supplements with a serum LDL-C lowering effect in the spectrum ranging from universal to care-related CVD risk management.

A wealth of data demonstrates a causal link between serum low-density lipoprotein cholesterol (LDL-C) concentrations and cardiovascular disease (CVD). Any decrease in serum LDL-C concentrations is associated with a decreased CVD risk, and this benefit is similar to a comparable LDL-C reduction after drug treatment and dietary intervention. Moreover, life-long reductions in serum LDL-C levels have a large impact on CVD risk and a long-term dietary enrichment with functional foods or supplements with a proven LDL lowering efficacy is therefore a feasible and efficient approach to decrease future CVD risk. Functional foods with an LDL-C lowering effect can improve health and/or a reduce the risk of disease. However, it has not been mentioned specifically whether this concerns mainly universal prevention or whether this can also be applied to the hierarchy towards care related prevention. Therefore, we here describe the effects of a list of interesting functional food ingredients with proven benefit in LDL-C lowering. In addition, we pay particular attention to the emerging evidence that the addition of these functional ingredients and supplements is advisable as universal and selective prevention in the general population. Moreover, functional ingredients and supplements are also helpful in care related prevention, i.e. in patients with elevated LDL-C concentrations who are statin-intolerant or are not able to achieve their LDL-C target levels. Furthermore, we will highlight practical aspects regarding the use of functional foods with an LDL-C lowering effect, such as the increasing importance of shared decision making of medical doctors and dieticians with patients to ensure proper empowerment and better adherence to dietary approaches. In addition, we will address costs issues related to the use of these functional foods, which might be a barrier in some populations.
