Liu CC, Lin HC. Are health claims in aging-related functional food packages different from those of general functional foods? Content analysis of food packaging from Taiwan. Front Public Health 2024; 12:1402969. [PMID: 38873292 PMCID: PMC11169814 DOI: 10.3389/fpubh.2024.1402969] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Accepted: 04/30/2024] [Indexed: 06/15/2024] Open
Abstract
Given the challenges of aging populations, both in Taiwan and globally, issues related to older consumers need more attention. According to surveys in Taiwan, food is one of the most important consumer products for older adults. In recent years, functional foods have become popular, often using health claims as a promotional tool. Therefore, this study has investigated food product packaging in common retail channels in Taiwan by conducting a content analysis of all items with health claims (160 samples). This study specifically compared products related to aging and those unrelated to aging. The results revealed that more than half the participants with health claims did not provide specific descriptions of their health effects. Furthermore, products related to aging often included health terms and claims to supplement with specific nutrients in their health claims. This study has aimed to offer recommendations for educating older consumers, regulating health claims in food advertising, promoting an age-friendly consumer environment, and consumer protection.

Public Health Nutr 2021; 24:5156-5165. [PMID: 33972003 PMCID: PMC11082796 DOI: 10.1017/s1368980021002007] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2021] [Revised: 04/04/2021] [Accepted: 05/06/2021] [Indexed: 11/07/2022]
Abstract
OBJECTIVE The excessive growth of the food supplements' industry highlights the need to focus attention on all aspects involved in their proper consumption; one that takes centre stage is advertising. The aim of this research is to analyse the presence of false and misleading claims in food supplements advertising. To this end, a relationship is established between the different types of health-related claims and the substances on which they are based, whether authorised or not by European Food Safety Authority (EFSA). DESIGN This empirical work conducts a content analysis of all radio mentions broadcast throughout 2017 on news/talk radio stations. SETTING Spain. PARTICIPANTS All radio mentions broadcast on news/talk commercial radio stations in Spain with the highest audience levels. The corpus is composed of 437 advertisements. RESULTS Results indicate that 80·3 % of function claims included in the analysed advertisements are not authorised by EFSA, while 20·4 % of disease claims are not allowed by EU regulation. Likewise, almost half of the substances referred to (43·7 %) are illicit: 54·1 % in function claims, 57·3 % in disease claims and 73·7 % in the case of reduction of disease risk claims. CONCLUSIONS This work reveals consistent failures to comply with European regulation on food supplements advertising. The widespread use of unauthorised health claims and substances is aggravated by the indirect recourse of illness as a persuasive argument, descriptions of alleged benefits as product attributes and the omission of essential information. This leads to dangerous misinformation and can pose serious health risks. Stronger legal mechanisms are needed for effective consumer protection.

Abstract
The aim of this paper is to investigate consumers' preferences and willingness to pay (WTP) for functional mozzarella cheese whose health benefits (reduced fat and enrichment in omega-3) are communicated by using nutrition claims (article 8) and health claims (articles 13 and 14) of the EU Regulation 1924/2006. In order to achieve the stated objective a choice survey was developed and administered to a sample of Italian respondents. The product attributes and attribute levels included in the choice experiment were obtained from in-depth interviews conducted with stakeholders working on the development of this new product in the Italian region of Puglia. Results show that many participants were not aware of functional food. Marketing segmentation performed via latent class analysis indicates that the development of this hypothetical product should be based on the addition of naturally enriched omega-3. In terms of health communication under Regulation 1924/2006, heterogeneity of preferences of the nine identified segments reveals that respondents have a clear preference for products from the Puglia region, for the combined nutrition claim over single nutrition claims and for the reduction of disease health claim (article 14) over the health claim (article 13). In monetary terms, willingness to pay for health claims is higher than nutrition claims.

Abstract
The outcome of the first series of health claim applications for probiotics in Europe as evaluated by the European Food Safety Authority (EFSA) has, up to 2013 almost completely yielded negative results. All recent applications also have been rejected, including the latest on prevention of mastitis in breastfeeding mothers. In other developed countries, such as Switzerland, Japan and Canada, the health effects of probiotics, for which scientific evidence has been provided, can be communicated to potential consumers. The number of clinical trials with probiotics over recent years shows a trend to level off or even decline. At the same time, clinical research into the role of (gut) microbiota in a wide variety of diseases and conditions is booming. Ultimately, this may offer new indications for gut microbiota management by probiotics, prebiotics or other food supplements.

Abstract
Based on the significance of oxidized low-density lipoprotein (LDL) in health and disease, this review focuses on human studies addressing oxidation of LDL, including three lines of biomarkers, (i) ex vivo LDL resistance to oxidation, a "challenge test" model, (ii) circulating oxidized LDL, indicating the "current in vivo status", and (iii) autoantibodies against oxidized LDL as fingerprints of an immune response to oxidized LDL, along with circulating oxysterols and 4-hydroxynonenal as biomarkers of lipid peroxidation. Lipid peroxidation and oxidized LDL are hallmarks in the development of various metabolic, cardiovascular and other diseases. Changes further occur across life stages from infancy to older age as well as in athletes and smokers. Given their responsiveness to targeted nutritional interventions, markers of LDL oxidation have been employed in a rapidly growing number of human studies for more than 2 decades. There is growing interest in foods, which, besides providing energy and nutrients, exert beneficial effects on human health, such as protection of DNA, proteins and lipids from oxidative damage. Any health claim, however, needs to be substantiated by supportive evidence derived from human studies, using reliable biomarkers to demonstrate such beneficial effects. A large body of evidence has accumulated, demonstrating protection of LDL from oxidation by bioactive food compounds, including vitamins, other micronutrients and secondary plant ingredients, which will facilitate the selection of oxidation biomarkers for future human intervention studies and health claim support.

Abstract
This article analyzes the debate about data acquisition and assessment in health claims regulation by identifying the underlying controversies on methodological choice. Regulation in the European Union imposes the need for a scientific substantiation of all health claims (claims about a relationship between consumption of certain food ingredients and positive health effects). Randomized controlled trials (RCTs) are the method that generally is considered to provide the highest quality data for decision making in claims regulation because they allow for establishing cause-effect relationships. The latter are demanded in European regulatory practice for authorization of a claim. This requirement has contributed to a debate about the advantages and limitations of the RCT methodology in nutrition research and regulation. Our analysis identifies five types of tensions that underlie the controversy, with respect to evidence, cognitive values, standards of proof, future lines of research, as well as expert judgment. We conclude that there is a direct and mutual interaction between methodological decisions in nutrition science, and different strategies in health claims regulation. The latter have social and public health consequences because not only may they affect the European market for functional foods, as well as concomitant consumption patterns, but also the generation of future regulation-relevant evidence in nutrition.

Abstract
The Association of Southeast Asian Nations aims to act as a single market and allow free movement of goods, services, and manpower. The purpose of this article is to present an overview of the current regulatory framework for health claims in Southeast Asia and to highlight the current barriers and opportunities in the regulatory frameworks in the Association of Southeast Asian Nations. To date, 5 countries in Southeast Asia, i.e., Indonesia, Malaysia, the Philippines, Singapore, and Thailand, have regulations and guidelines to permit the use of health claims on food products. There are inconsistencies in the regulations and the types of evidence required for health claim applications in these countries. A clear understanding of the regulatory frameworks in these countries may help to increase trade in this fast-growing region and to provide direction for the food industry and the regulatory community to develop and market food products with better nutritional quality tailored to the needs of Southeast Asian consumers.

Abstract
The finding that people who eat the most whole grains have a lower risk of cardiovascular disease and diabetes, compared with those who eat the least, is one of the most consistent findings in nutritional epidemiology. However, criteria for reporting whole-grain intake have varied widely, making it difficult to precisely explore the relation of whole grains and grain components with health outcomes. To enable better understanding of the health benefits of whole grain-rich diets, we propose that both observational and intervention studies should as far as possible be required to report as follows when describing whole grains: 1) quantify the amount of whole grain in the food or product in grams on a dry-weight basis, 2) describe the whole-grain definition used, 3) report and separate the different types of grains used, 4) if possible, report the structure of the grains (intact, crushed, partially milled) in foods, and 5) describe the main types of products used and processes used to make them. Added bran and germ should be reported distinctly from whole grains. In addition, we strongly recommend the incorporation of biomarkers of whole-grain intake to check compliance to intervention diets and help attenuate for errors in dietary recall of whole-grain intake. Of these measures, reporting whole-grain intake in grams is essential for future research work in the area. Improving reporting and estimation of whole-grain intake will enable easier comparison between different studies and lead to stronger meta-analyses in the future.

Abstract
AbstractObjectiveFood packages were objectively assessed to explore differences in nutrition labelling, selected promotional marketing techniques and health and nutrition claims between countries, in comparison to national regulations.DesignCross-sectional.SettingChip and sweet biscuit packages were collected from sixteen countries at different levels of economic development in the EPOCH (Environmental Profile of a Community’s Health) study between 2008 and 2010.SubjectsSeven hundred and thirty-seven food packages were systematically evaluated for nutrition labelling, selected promotional marketing techniques relevant to nutrition and health, and health and nutrition claims. We compared pack labelling in countries with labelling regulations, with voluntary regulations and no regulations.ResultsOverall 86 % of the packages had nutrition labels, 30 % had health or nutrition claims and 87 % displayed selected marketing techniques. On average, each package displayed two marketing techniques and one health or nutrition claim. In countries with mandatory nutrition labelling a greater proportion of packages displayed nutrition labels, had more of the seven required nutrients present, more total nutrients listed and higher readability compared with those with voluntary or no regulations. Countries with no health or nutrition claim regulations had fewer claims per package compared with countries with regulations.ConclusionsNutrition label regulations were associated with increased prevalence and quality of nutrition labels. Health and nutrition claim regulations were unexpectedly associated with increased use of claims, suggesting that current regulations may not have the desired effect of protecting consumers. Of concern, lack of regulation was associated with increased promotional marketing techniques directed at children and misleadingly promoting broad concepts of health.

Abstract
OBJECTIVES Fruit and vegetable claims on food packages are not regulated under Australian food standards. The present study aimed to: (i) investigate the number and healthiness of products carrying fruit and vegetable claims in Australia; and (ii) compare the nutrition composition of these products with fresh fruit and/or vegetables. DESIGN Content analysis of fruit and vegetable claims on food packages. The Australian food standards nutrient profiling model was used to determine the proportion of products not meeting nutrient profiling criteria. The nutrient composition of products carrying claims referencing the servings of fruit and vegetables in the product were compared with that of the dominant fruit and/or vegetables in each product. SETTING The five largest supermarket chains in Australia. SUBJECTS All available products in the fruit snacks, soups and fruit and vegetable juices/fruit drinks categories (n 762) were surveyed. Nutrition composition, ingredients and claims were recorded for each product. RESULTS Of the products surveyed, 48 % (n 366) carried at least one claim, of which 34 % (n 124) did not meet nutrient profiling. Products carrying claims referencing the number of servings of fruit and vegetables had more energy, sodium, saturated fat and sugar, and less fibre, than fresh fruit and/or vegetables (all P<0·001). CONCLUSIONS Many products carried fruit and vegetable claims and were significantly higher in energy, saturated fat, sugars and sodium than fresh fruit and vegetables. Marketing these products as a way of meeting fruit and vegetable intake is inaccurate and potentially misleading. Fruit and vegetable claims should be regulated using nutrient profiling.

Abstract
OBJECTIVES The objective of this study is to provide details on probiotic supplement use among young children in Taiwan. PARTICIPANTS AND METHODS This study is based on the Taiwan Birth Cohort Study database. We used questionnaires to collect information on probiotic supplement use among young children from birth to 18 months of age, while also considering their demographic characteristics and other covariates. Low-birth-weight infants, preterm infants, those with birth defects, and those with caregivers who returned incomplete questionnaires were excluded. The final valid sample comprised 16,991 cases. RESULTS Approximately half the children received probiotic supplements before the age of 18 months. Only 6.3% of the children received probiotic supplements during the two periods of birth to 6 months and 7 to 18 months. Firstborn children, native mothers, mothers with higher educational levels, higher family income, and parents who lead healthy lifestyles were positively related to probiotic supplement use among children. Young children who were breastfed, with eczema, or with gastrointestinal tract problems were significantly positively associated with probiotic supplement use. CONCLUSION The findings show that probiotic supplement usage among young children is associated with a more socially advantaged circumstance and certain child health factors, such as eczema, diarrhea, and constipation. Parents might use probiotic supplements for prevention or treatment of child diseases. The findings of this research could serve as a baseline for future studies, and provide insight into probiotic supplement use behavior for health professionals caring for infants and young children.

Abstract
INTRODUCTION In 2006, the European Parliament and Council issued a regulation (No. 1924/2006) for the nutrition and health claims made on foods, including food supplements. According to the regulation, the use of nutrition and health claims shall only be permitted if the substance in respect of which the claim is made has been shown to have a beneficial nutritional or physiological effect. In the field of joint and cartilage health, there is no clear scientific-based definition of the nature of such a beneficial nutritional or physiological effect. The objective of this paper is to scientifically define the possible content of health claims related to joint and cartilage health and to provide scientific guidelines for the design of clinical studies which need to be adopted to substantiate such health claims. METHODS Literature review up to September 2011 followed by a consensus expert discussion organized by the Group for the Respect of Ethics and Excellence in Science (GREES). RESULTS In line with the general principles of the PASSCLAIM and the Codex recommendations, the GREES identified four acceptable health claims related to joint and cartilage health based on the effects on discomfort, joint and cartilage structural integrity or risk factors for joint and cartilage diseases. The GREES considers that randomized controlled trials on a relevant outcome is the best design to assess health claims. Moreover, animal studies could also be of interest to substantiate some health claims, to assess the clinical relevance of endpoints used in human studies or to extrapolate data obtained in patients to the target (apparently) healthy population. CONCLUSION According to the methodology and biomarkers used in the study and whether or not additional animal studies are provided to support the claim, various health claims can be acceptable in the field of joint and cartilage health.

Abstract
UNLABELLED Health claims for food products in Europe are permitted if the nutrient has been shown to have a beneficial nutritional or physiological effect. This paper defines health claims related to bone health and provides guidelines for the design and the methodology of clinical studies to support claims. INTRODUCTION Regulation (EC) no. 1924/2006 on nutrition and health claims targeting food products was introduced in Europe stating that health claims shall only be permitted if the substance in respect of which the claim is made has been shown to have a beneficial nutritional or physiological effect. The objective of this paper is to define health claims related to bone health and to provide guidelines for the design and the methodology of clinical studies which need to be adopted to assert such health claims. METHODS Literature review followed by a consensus discussion during two 1-day meetings organized by the Group for the Respect of Ethics and Excellence in Science (GREES). RESULTS The GREES identified six acceptable health claims related to bone health based on the potential of food products to show an effect on either the bioavailability of calcium or osteoclast regulatory proteins or bone turnover markers or bone mineral density or bone structure or fracture incidence. The GREES considers that well-designed human randomized controlled trial on a relevant outcome is the best design to assess health claims. The substantiation of health claim could also be supported by animal studies showing either an improvement in bone strength with the food product or showing the relationship between changes induced by the food product on a surrogate marker and changes in bone strength. CONCLUSION The consensus reached is that the level of health claim may differ according to the surrogate endpoint used and on additional animal studies provided to support the claim.

Abstract
In Europe, for authorisation of a health claim, applicants must follow the procedures in the legislation and in the guidelines for submission of a dossier set out by the European Food Safety Authority. The Functional Foods in Europe (FUFOSE) and Process for the Assessment of Scientific Support for Claims on Foods (PASSCLAIM) projects underpinned the laws and provided criteria against which the quality of the totality of the available data could be judged. Whereas the regulations and PASSCLAIM require an assessment of the extent to which cause and effect can be demonstrated between a food category, a food or constituent and a health benefit, the European Food Safety Authority requires conclusive evidence of cause and effect. This latter standard of proof and a focus on randomised controlled trials done on isolated components and using validated physiological biomarkers may not always be appropriate to assess nutrition science. The aims of this paper are to address the strengths and weaknesses of different sources of evidence that contribute to the totality of the available data, to undertake a critical examination of the application of a drug-like assessment model in evidence-based nutrition and to encourage research on new biomarkers of health and homeostatic adaptability. There is a need for (a) a robust and pragmatic scientific framework for assessing the strength, consistency and biological plausibility of the evidence, and (b) consumer understanding research on claims that use qualifying language and/or graphics to reflect the weight of evidence. Such scientific, policy and communication approaches are proportionate and could help stimulate academic research, promote fair trade and product innovation and contribute to consumer education about food and health.

Abstract
EU legislation on nutrition and health claims made on foods (Regulation (EC) No. 1924/2006) specifies that health claims should be only authorised for use in the Community after a scientific assessment of the highest possible standard is carried out by the European Food Safety Authority (EFSA). This paper focuses on the scientific substantiation of health claims within the context of the EU Regulation. The evaluation of the substantiation of health claims is carried out by the EFSA Scientific Panel on Dietetic Products, Nutrition and Allergies (NDA). The EFSA has published extensive guidance to assist applicants in the preparation of applications for authorisations of health claims. This guidance summarises the general principles applied by the NDA Panel in the evaluation of health claims, including the scientific criteria for substantiation, as well as the scientific requirements for the substantiation of specific health claims. To date, the EFSA NDA Panel has concluded that a wide range of health claims has been substantiated. These include claims for many well-established functions of nutrients, as well as beneficial effects of foods and food constituents on a range of body functions. In addition, claims have been substantiated on the role of nutrients in growth and development of children and on the effects of nutrients and food constituents on reduction of risk factors for disease. EFSA evaluations and guidance have made an important contribution to the understanding of the scientific substantiation of health claims which will help to set new directions for research and will guide future innovation.

Abstract
Benefit-risk assessment in food and nutrition is relatively new. It weighs the beneficial and adverse effects that a food (component) may have, in order to facilitate more informed management decisions regarding public health issues. It is rooted in the recognition that good food and nutrition can improve health and that some risk may be acceptable if benefit is expected to outweigh it. This paper presents an overview of current concepts and practices in benefit-risk analysis for food and nutrition. It aims to facilitate scientists and policy makers in performing, interpreting and evaluating benefit-risk assessments. Historically, the assessments of risks and benefits have been separate processes. Risk assessment is mainly addressed by toxicology, as demanded by regulation. It traditionally assumes that a maximum safe dose can be determined from experimental studies (usually in animals) and that applying appropriate uncertainty factors then defines the 'safe' intake for human populations. There is a minor role for other research traditions in risk assessment, such as epidemiology, which quantifies associations between determinants and health effects in humans. These effects can be both adverse and beneficial. Benefit assessment is newly developing in regulatory terms, but has been the subject of research for a long time within nutrition and epidemiology. The exact scope is yet to be defined. Reductions in risk can be termed benefits, but also states rising above 'the average health' are explored as benefits. In nutrition, current interest is in 'optimal' intake; from a population perspective, but also from a more individualised perspective. In current approaches to combine benefit and risk assessment, benefit assessment mirrors the traditional risk assessment paradigm of hazard identification, hazard characterization, exposure assessment and risk characterization. Benefit-risk comparison can be qualitative and quantitative. In a quantitative comparison, benefits and risks are expressed in a common currency, for which the input may be deterministic or (increasingly more) probabilistic. A tiered approach is advocated, as this allows for transparency, an early stop in the analysis and interim interaction with the decision-maker. A general problem in the disciplines underlying benefit-risk assessment is that good dose-response data, i.e. at relevant intake levels and suitable for the target population, are scarce. It is concluded that, provided it is clearly explained, benefit-risk assessment is a valuable approach to systematically show current knowledge and its gaps and to transparently provide the best possible science-based answer to complicated questions with a large potential impact on public health.

Abstract
Human studies provide evidence for beneficial effects of polyphenol-rich foods on cardiovascular health. The antioxidant activity of polyphenols potentially explains these effects, but is the antioxidant activity a reliable predictor for these effects? An International Life Sciences Institute Europe working group addressed this question and explored the potential of antioxidant claims for polyphenols in relation to cardiovascular health by using the so-called Process for the Assessment of Scientific Support for Claims on Foods project criteria. In this process, analytical aspects of polyphenols, their occurrence in foods, dietary intake, and bioavailability were reviewed. Human studies on polyphenols and cardiovascular health were reviewed together with methods for biomarkers of oxidative damage and total antioxidant capacity (TAC). In retrospective studies, F2-isoprostanes and oxidized LDL, the most reliable biomarkers of lipid peroxidation, and measures for TAC showed the expected differences between cardiovascular disease patients and healthy controls, but prospective studies are lacking, and a causal relationship between these biomarkers and cardiovascular health could not be established. Therefore, the physiological relevance of a potential change in these biomarkers is unclear. We found limited evidence that some types of polyphenol-rich products modify these biomarkers in humans. A direct antioxidant effect of polyphenols in vivo is questionable, however, because concentrations in blood are low compared with other antioxidants and extensive metabolism following ingestion lowers their antioxidant activity. Therefore, the biological relevance of direct antioxidant effects of polyphenols for cardiovascular health could not be established. Overall, although some polyphenol-rich foods exert beneficial effects on some biomarkers of cardiovascular health, there is no evidence that this is caused by improvements in antioxidant function biomarkers (oxidative damage or antioxidant capacity).

Abstract
The protection of European consumers from the false or misleading scientific and nutritional claims of food manufacturers took a step forward with the recent opinions of the European Food Safety Authority (EFSA). As a risk assessment agency, the EFSA recently assessed and rejected a vast number of food claim forcing the withdrawal of many claims from leading manufacturers. Focusing on the functional food sector, consumer protection issues, and market impacts, this article looks into the role of the EFSA and examines the rejection of claims based on bad and misleading science and outlines how the EFSA map claims and distinguishes between the good and bad scientific methods.

Abstract
The European Union is implementing a new regulatory framework for nutrition and health claims (HCs) that will greatly impact the communication of health messages on foodstuffs. In particular, approved HCs will be included in a positive register of generic claims. In the currently available literature, assessment of the relevance of HCs has mainly been related to scientific substantiation, and the issue of relevance in terms of public health has tended to be overlooked. Interestingly, the new regulation states that claims must be well understood by the average consumer. This article delves beyond the issue of scientific substantiation of claims and reviews possible discrepancies between consumer perception/understanding of HCs and the public health nutrition reality, which can confuse or mislead the consumer and ultimately impact public health nutrition. Six pitfalls are described herein and a comprehensive overview of the critical examination of any HC is proposed.

Abstract
BACKGROUND European Regulation 1924/2006 states that all health claims made on foods need to be substantiated scientifically. OBJECTIVE To apply the PASSCLAIM criteria for the scientific substantiation of health claims on foods to herbal supplements containing Ginkgo biloba. Evaluation of three selected claimed health effects for G. biloba (improvement of blood circulation, improvement of symptoms of old age, and improvement of memory) was achieved through review of publicly available scientific data. A total of 35 human intervention studies were evaluated. Commercially available products claimed to contain mainly G. biloba (N=29) were randomly sampled in the Netherlands and analyzed for their content on ginkgo extract. Also, a toxicological risk assessment was performed. RESULTS The three selected health claims investigated could not be substantiated. This was mainly because of a lack of data from studies in healthy volunteers. In most studies results performed with a 24% standardized G. biloba extract were described. However, our chemical analysis showed that 25 of the 29 sampled products did not contain the required minimum 24% standardized extract. Moreover, in most preparations the content of substances typical for G. biloba did not conform to what was declared on the label. Since toxicity data for G. biloba are very limited, a safety limit could not be established. CONCLUSIONS Evidence is lacking for three health claims of herbal products with G. biloba. Neither safety nor efficacy can be guaranteed at the recommended daily dose. The multidisciplinary approach described in this paper provides good insight into issues that are relevant for the evaluation of health claims for herbal food supplements.

Abstract
The present report summarises a meeting held by the Food & Health Forum at the Royal Society of Medicine, London, on 27 May 2010. The objective of the meeting was to review the problems associated with the use of evidence-based nutrition and to discuss what constitutes the efficacy for foods and food constituents and how the strength and consistency of the evidence can be assessed and adapted to circumstances in which health claims are to be used on food products. The meeting highlighted the limitations with the present evidence-based nutrition models with the prospect that this may have long-term consequences for nutrition science and ultimately the consumer who may not benefit from new science that could have an impact on health.

Abstract
Abstract Information regarding the use of functional foods and nutraceuticals (FFN) in combating disease is rarely communicated to health care practitioners as medicinal strategies for patients. Metabolic syndrome (MetS) is an ideal paradigm for demonstrating the therapeutic properties of FFN. Encompassing multiple etiologies, including atherogenic dyslipidemia, insulin resistance, and hypertension, MetS affects over a third of American adults. However, as disease-related risk factors accumulate over time, guidelines for treating disorders of MetS progressively de-emphasize the use of FFN. Using marine omega-3 fatty acids, plant sterols, fiber, and tomato extract as examples, the purpose of this review is to endorse FFN as long-term adjunctive therapies to pharmaceutical treatment for disorders and risk factors for MetS. An additional goal is to compare physiological and molecular targets of FFN against corresponding prescription medications. Results reveal that FFN are viable treatment strategies for disorders of MetS, complementing pharmacological interventions by targeting and improving the biological processes that foster the development of disease. Thus, efficacious FFN therapies should be emphasized throughout all stages of treatment as adjuncts to pharmacotherapy for disorders of MetS. Accordingly, new developments in FFN research must be implemented into clinical guidelines with the prospect of improving disease prognoses as accessories to prescription medications.

Abstract
BACKGROUND Within the framework of Codex Alimentarius, attempts are being made at international level to establish guidelines for use of nutrition and health claims. An important issue that has to be addressed is the process of scientific substantiating of claims on foods. OBJECTIVE To provide an insight into the current step procedure of the proposed draft recommendations on the scientific basis of health claims. These Codex recommendations are intended to facilitate governments' own evaluation of health claims made by the industry. METHODS Review of comments of governments, observers and non-governmental organizations (NGOs) and relevant references to the proposed draft recommendations of the last sessions of the Codex Committee on Nutrition and Food for Special Dietary Uses (CCNFSDU). A literature search was performed using the PubMed database. RESULTS/CONCLUSIONS Several proposed draft recommendations on the scientific substantiation of health claims have been considered and amended by the CCNFSDU in recent years but the work is not yet complete. The current work draws on the work of FUFOSE and PASSCLAIM and also on that of WHO and FDA. Given the important role of Codex in food safety, the draft recommendations emphasize circumstances where additional evaluation of safety or nutritional safety needs to be considered. High quality human intervention studies are the prime evidence needed to substantiate claims but there is recognition that, in some cases, only observational studies may be available. Animal and in vitro studies will also be evaluated as part of the totality of the evidence. It has been suggested that the recommendations should include re-evaluation of claims after a certain time period, or if new evidence calls into question the scientific validity underpinning the claims. Setting out a common approach for the substantiation of health claims is an important step in the use of health claims around the world. There is a need to reflect emerging as well as consensus science. The substantiating evidence should be proportionate to the claim. Further progress in the elaboration of this relevant Codex text is needed to reach consensus.

Abstract
Objective Available reports on adherence to recommended guidelines for labeling of probiotic products are based on assessment of these products in developed countries. In the Arabian Gulf region, there is a paucity of data on the characterization of probiotic products and an absence of local guidelines for their labeling. This study, carried out in the United Arab Emirates (UAE), represents the first evaluation of probiotic products available in the Arabian Peninsula. Methods Probiotic products were purchased over the counter from a variety of sources, including pharmacies, healthfood stores, and supermarkets across the UAE. All identified products were listed and information regarding type of product preparation and labeling information were recorded. Results A total of 37 probiotic products, 15 dairy-based and 22 non-dairy-based were identified. The dairy products comprised of 12 yogurts, two fermented milk products and one powdered baby formula. The majority of non-dairy products were in capsule form (n = 16). While all the non-dairy products gave information about the strain of probiotic microorganism and number present at time of manufacture, this information was provided for only one dairy-based product. Strains of Lactobacillus acidophilus were the most common probiotic organisms identified. However, one probiotic product listed Enterococcus faecalis (750 million viable bacteria per capsule) as a component. With the exception of one non-dairy-based product, all health-related claims were structure/function statements, according to the US Food and Drug Administration nomenclature. Conclusion These findings indicate that a wide variety of probiotic products are available in the Arabian Gulf. Development of guidelines for labeling of these probiotic products and use of structure/function statements and health claims should be addressed.

Abstract
As the health benefits of ingesting live bacteria become more evident, foods are now being produced that contain probiotic bacteria. The data to support label health claims for probiotic products are often difficult to provide. The experimental evidence to identify probiotic microorganisms and to demonstrate their efficacy in clinical trials is more challenging than for other potential functional foods because effects are mediated by living microorganisms and may therefore be influenced by the status of these microorganisms. Clinical trials to show efficacy are expensive. Obtaining appropriate samples is difficult. A scientific consensus is building to support the claim that the ingestion of certain probiotic bacteria reduces lactose intolerance and can reduce the duration of rotavirus diarrheas. Some probiotic bacteria have "generally accepted as safe" status; proof of the safety of any probiotic is essential. Japanese health regulatory officials, using their Foods for Specific Health Use system, have approved human health claims for over 20 probiotic products. On the other hand, at this time, no probiotic product is sold in Canada that carries a label health claim. This illustrates the considerable discrepancies across countries in perception of health effects of probiotics.

Abstract
Interest in the health effects of foods by both industry and consumers has put a spotlight on the role of health claims on foods in Canada. The current regulatory framework governing the use of different health claims on foods in Canada is described and compared with international approaches. Similarities were observed in how risk-reduction claims for serious diseases are managed in the United States, European Union and proposed by Food Standards Australia New Zealand, including the need for premarket authorization and the requirement for a high level of certainty based on the totality of evidence in substantiating this type of claim. However, approaches to permitting function claims other than those for the well-established functions of known nutrients are divergent among the jurisdictions compared. Canada also differs from other jurisdictions in not establishing core nutritional criteria for foods carrying disease risk-reduction claims. A brief overview of the status in Canada of a number of disease risk-reduction claims that have been approved in the United States, based on significant scientific agreement under the Nutrition Labeling and Education Act or through authoritative statements under the Food and Drug Administration Modernization Act, is also provided.

Abstract
Worldwide consumer interest in functional foods and their potential health benefits has been increasing over the past 10 y. To respond to this interest, regulatory bodies have developed guidelines for assessing health claims on functional foods. The objective of this article is to investigate the type and amount of evidence needed in various jurisdictions on a worldwide basis to substantiate both generic and product-specific health claims. Two types of health claims were examined using separate case studies. Analysis of generic health claims was highlighted by (n-3) fatty acids and their relation to heart health; whereas examination of product-specific health claims was conducted using probiotics and their association with gastrointestinal well-being. Results showed a common core for use of convincing high-quality human data, especially in the form of randomized controlled trials (RCT), but there was significant variability in the type and amount of scientific evidence needed to substantiate health claims, both generic and product specific, across different jurisdictions. Product-specific claims tended to use human RCT as the main basis for claims, whereas generic claims tended to base their statements on a wider spectrum of literature.

Abstract
Epidemiological investigations suggest that soy consumption may be associated with a lower incidence of certain chronic diseases. Clinical studies also show that ingestion of soy proteins reduces the risk factors for cardiovascular disease. This led to the approval of the food-labeling health claim for soy proteins in the prevention of coronary heart disease by the U.S. FDA in 1999. Similar health petitions for soy proteins have also been approved thereafter in the United Kingdom, Brazil, South Africa, the Philippines, Indonesia, Korea, and Malaysia. However, the purported health benefits are quite variable in different studies. The Nutrition Committee of the American Heart Association has assessed 22 randomized trials conducted since 1999 and found that isolated soy protein with isoflavones (ISF) slightly decreased LDL cholesterol but had no effect on HDL cholesterol, triglycerides, lipoprotein(a), or blood pressure. The other effects of soy consumption were not evident. Although the contributing factors to these discrepancies are not fully understood, the source of soybeans and processing procedures of the protein or ISF are believed to be important because of their effects on the content and intactness of certain bioactive protein subunits. Some studies have documented potential safety concerns on increased consumption of soy products. Impacts of soy products on thyroid and reproductive functions as well as on certain types of carcinogenesis require further study in this context. Overall, existing data are inconsistent or inadequate in supporting most of the suggested health benefits of consuming soy protein or ISF.

Abstract
Establishing the evidence for health claims involves reviewing the available body of scientific knowledge and linking this to statements meaningful to consumers. This requires an understanding of scientific merit as well as consumer perceptions of health messages. Food Standards Australia New Zealand sets standards for current nutrient content claims and is close to approving a proposed new framework for all forms of nutrition and health claims on foods. This article discusses this proposed health claims standard in light of the challenges health claims pose to nutrition science. It critically describes the framework for the standard, reviews issues related to substantiation of claims, and provides commentary on the proposed assessment of evidence. This spectrum of permission reflects the use of food in health promotion, disease prevention, and early disease management when therapeutic agents may not be required. The position is consistent with an understanding that food delivers nutrients and bioactive substances at levels that support the improved health of the human organism in the early stages of the health-disease spectrum. Increasing knowledge of the role of food components and its intelligent application in dietary modification can result in this strategy playing a major role in disease prevention and early disease management. The amount of evidence required to enable health claim labeling should be based on a reasonable judgment and clear understanding of the role of nutrition in health and disease.

Abstract
Government-approved health claims support dietary intervention as a safe and practical approach to improving consumer health and provide industry with regulatory guidelines for food product labels. Claims already allowed in the United States, United Kingdom, Sweden, and The Netherlands for reducing cholesterol through consumption of oat or barley soluble fiber provide a basis for review, but each country may have different criteria for assessing clinical evidence for a physiological effect. For example, the FDA-approved barley health claim was based on a petition that included 39 animal model studies and 11 human clinical trials. Since then, more studies have been published, but with few exceptions, clinical data continue to demonstrate that the consumption of barley products is effective for lowering total and LDL cholesterol. More research is needed to fully understand the mechanism of cholesterol reduction and the role of beta-glucan molecular weight, viscosity, and solubility. In an assessment of the physiological efficacy of a dietary intervention, consideration should also be given to the potential impact of physical and thermal food-processing treatments and genotypic variation in the barley source. New barley cultivars have been generated specifically for food use, possessing increased beta-glucan, desirable starch composition profiles, and improved milling/processing traits. These advances in barley production, coupled with the establishment of a government-regulated health claim for barley beta-glucan, will stimulate new processing opportunities for barley foods and provide consumers with reliable, healthy food choices.

Abstract
This article provides an overview of the procedures involved in scientific substantiation of functional food health claims in China. The definition of a functional food is discussed, in addition to the factors that led to its modification in 2005. The framework of administration includes the regulation of functional foods, steps involved in submission of dossiers, the safety control system for raw materials and products, and technical procedures for testing and evaluation. Scientific evidence required for a claim includes evidence from product tests in addition to evidence resulting from complete scientific literature searches relative to the food material or component in question. Currently, the 4 main rules for functional food assessment in China include 1) functional assessment procedures; 2) standard toxicological assessment; 3) regulations on nutrient supplements; and 4) standard analytical methods for functional components. The current situation for functional foods in China is analyzed, including a discussion of the distribution of the 27 currently allowed functional food health claims. The effectiveness of functional foods and health claims for improving health relies largely on the motivation and education of the public to be able to make good choices.

Abstract
Health claims in the United States have been a topic of intense controversy since the mid-1980s. Three categories of claims can currently be used on food and dietary supplement labels in the United States: 1) health claims, 2) nutrient content claims, and 3) structure/function claims. Structure/function claims were authorized under the Dietary Supplement Health and Education Act and describe the effect of a dietary supplement on the structure or function of the body. Nutrient content claims are used to describe the percentage of a nutrient in a product relative to the daily value. Health claims describe a relation between a food, food component, or dietary supplement ingredient and reducing risk of a disease or health-related condition. Health claims are based on a very high standard of scientific evidence and significant scientific agreement. Are U.S. health claims really benefitting public health? Recent evidence suggests that this mode of communication has had limited success and in fact may be misleading to consumers.

Abstract
In the early 1980s the Japanese scientific academy defined a functional food as a food having a tertiary or physiologically active function. The current Japanese "Food with Health Claims" include 2 categories. For the first category, "Food with Nutrient Function Claims," the label may be freely used if a product satisfies the standard for the minimum and maximum levels per daily portion usually consumed. The second category is defined as "Food for Specified Health Uses" (FOSHU). FOSHU foods are those that contain dietary ingredients that have beneficial effects on the physiological functions of the human body, maintain and promote health, and improve health-related conditions. Health claims on these foods correspond to the category of "other" function claims of the Codex Alimentarius. However, claims of disease-risk reduction are not currently allowed under FOSHU with an exception for calcium and folic acid. Manufacturers can emphasize the characteristics of their products and promote sales by labeling or claims. Therefore, the labeling should be clear and correct and avoid any chance of misinterpretation. The labeling of health claims on foods should always be based on scientific evidence. Any manufacturer who applies to the government for approval under the FOSHU code for its product must tabulate both published available publications and internal reports on the effectiveness of the product and/or its ingredients and provide a summary of each available publication or report. The tabulation must include in vitro metabolic and biochemical studies, in vivo studies, and randomized controlled trials on Japanese people. The overall philosophy of the Ministry is to maintain and improve the health status of people and to prevent chronic noncommunicable diseases through an approach that involves a well-balanced diet as well as through the use of "health foods" including "Food with Health Claims."
