A Graded Approach for Evaluating Health Claims about Plant-Based Food Supplements: Application of a Case Study Methodology.

The implementation of REGULATION (EC) No 1924/2006 has led to the formation of a list of health claims that can be used in food supplements (EU 432/2012). However, such supplements are often composed of plant preparations with claims omitted from this list. The peculiarity of plants is related to their long history of use, that could allow claims based on traditionally recognized health effects. In addition, the scientific literature has been enriched over the years through clinical studies that have assessed the bioavailability and efficacy of bioactive components, and investigated their mechanisms of action. Based on existing recognized models which aim to classify research according to the level of scientific evidence, Synadiet developed a three-grade model (A, B or C) for assessing plants health claims. In this paper, the applicability of the model is illustrated through an example for which a Grade B health claim attesting the possible contribution of red clover isoflavones to the improvement of blood lipid levels in postmenopausal women has been attributed. The model appears able to be easily extrapolated to claims pertaining to other plants. If adopted by consensus at European level, this model could initiate the implementation of a positive list of health claims on plant preparations.

Alegações nutricionais e o real benefício para o consumidor de biscoitos infantis / Nutritional claims and the real benefit for the child biscuit consumer

Atualmente, observa-se o aumento do consumo de biscoitos infantis que são acrescidos com micronutrientes. O objetivo desse artigo é avaliar o valor nutricional e seu benefício para esse público. Foram analisados 16 (dezesseis) rótulos de biscoitos infantis, contendo alegações de fonte de vitaminas e minerais. A avaliação foi baseada na Portaria nº 31/98 sobre Regulamento Técnico, referente a alimentos adicionados de nutrientes essenciais, e na Portaria nº 33/98, sobre a Ingestão Diária Recomendada para Lactantes e Crianças. Os dados tabulados foram divididos em três gráficos: primeiro para Conformidade dos Rótulos; segundo da Quantidade dos Micronutrientes de Acordo com a Portaria nº 33/98; e terceiro Análise da Porção de Acordo com IDR para Lactantes e Crianças da Portaria nº 33/98. Dos biscoitos analisados, 94% estavam em conformidade quanto às informações contidas nos rótulos. Em relação à quantidade dos micronutrientes, as vitaminas B1, B2 e B3 apresentaram valores superiores ao recomendado. Conclusão: Os rótulos dos biscoitos avaliados não apresentaram de forma clara as informações necessárias para o consumidor. É necessário construir normas mais específicas direcionadas às atribuições nutricionais nas rotulagens, com uma linguagem mais acessível para a sociedade.(AU)

Currently, there is an increase in the consumption of children's cookies that are added with micronutrients. The article's purpose is to assess the nutritional value and its benefit for this audience. 16 (Sixteen) children's biscuit labels were analyzed, holding claims from source of vitamins and minerals. The evaluation of this was based on Portaria nº 31/98 about Regulamento Técnico regarding foods added with essential nutrients and on Portaria nº 33/98 about Recommended Daily Intake for Lactants and Children. The charted data were divided into three graphs: First for Label Compliance; Second for Quantity of Micronutrients According to Portaria nº 33/98; And third Analysis from the Portion of Agreement with IDR for Lactating and Children of Portaria nº 33/98. From the analyzed cookies, 94% were in compliance with the information on the labels. Regarding to the amount of micronutrients, the vitamins B1, B2 and B3 showed higher values than recommended. Conclusion: The labels of the evaluated cookies did clearly present the necessary information for the consumer. It is necessary to build more specific norms directed to the nutritional attributions in the labels, with a language more accessible to society.(AU)

[Nutritional labeling and amino acid profile in high protein Chilean dairy products: a new alternative for health and sports]. / Etiquetado nutricional y perfil de aminoácidos en lácteos chilenos altos en proteína: nueva alternativa para la salud y el deporte.

INTRODUCTION: Introduction: protein is an essential nutrient that can be obtained through different food sources. In recent years, a growing development in the food industry of dairy products with higher protein content has emerged in the national market. Métodos: the present work analyzed the nutritional information, protein content, and amino acid profile of high protein yogurts. Five main brands of high-protein yogurt (PY) were selected, as was a sample of regular yogurt (RY), and one of whey protein isolate (WP), which underwent a proximal analysis and amino acid profile by high-performance liquid chromatography (HPLC). Results: it was observed that the protein content of the analyzed YP ranged between 7.2 and 15.1 g/portion, representing 6.8 % to 11 % of total content, twice the content of YBAT (3,4 %). Regarding carbohydrates and fats, these were found to range between 6.25 and 13.5 g/serving and 0.9 and 5.3 g/serving, respectively. Leucine content of the PY varied between 0.6 and 1.5 g/portion, which was higher than RY (0.3 g/portion) and lower than WP (2.2 g/portion). The sum of essential amino acids was found to be between 3 and 6.9 g/portion in PY, 1.7 g/serving y 8.5 g/serving in WP. Conclusion: these results show that PYs are a good alternative to promote a correct protein intake, similar to proteins for sports use, so their recommendation could be useful to promote consumption in different populations according to their needs.

INTRODUCCIÓN: Introducción: la proteína es un nutriente esencial que se puede obtener a través de diferentes fuentes alimentarias . En los últimos años, un creciente desarrollo de la industria alimentaria de productos lácteos con mayor aporte en proteínas ha surgido en el mercado nacional. Métodos: el presente trabajo analizó la información nutricional, el contenido proteico y el perfil de aminoácidos de una serie de yogures altos en proteína. Se seleccionaron 5 principales marcas de yogures altos en proteína (YP), una muestra de yogur batido (YBAT) y una de proteina de suero de leche aislado (WP) a las que se realizó un análisis proximal y un perfil de aminoácidos por cromatografía líquida de alto rendimiento (HPLC). Resultados: se pudo observar que el contenido de proteína de los YP analizados varió entre 7,2-15,1 g/porción, lo que representa del 6,8 al 11 % del contenido total, el doble del contenido del YBAT (3,4 %). Respecto a los hidratos de carbono y grasas, estos se encontraron entre 6,25 y 13,5 g/porción y 0,9 y 5,3 g/porción, respectivamente. El contenido de leucina de los YP varió entre 0,6 y 1,5 g/porción, con valores superiores a los de los YBAT (0,3 g/porción) e inferiores a los de las WP (2,2 g/porción). La suma de aminoácidos esenciales se encontró entre 3 y 6,9 g/porción en los YP, en 1,7 g/porción en los YBAT y 8,5 g/porción en las WP. Conclusión: estos resultados demuestran que los YP son una buena alternativa para promover una correcta ingesta proteica, semejante a las proteínas de uso deportivo, por lo que su recomendación podría ser útil para promover su consumo en diferentes poblaciones según sus necesidades.

Nutrition Claims on Fruit Drinks Are Inconsistent Indicators of Nutritional Profile: A Content Analysis of Fruit Drinks Purchased by Households With Young Children.

BACKGROUND: Fruit drinks are the most commonly consumed sugar-sweetened beverage among young children. Fruit drinks carry many nutrition-related claims on the front of package (FOP). Nutrition-related claims affect individuals' perceptions of the healthfulness of products and purchase intentions, often creating a "health halo" effect. OBJECTIVE: The aims of this study were to describe the prevalence of FOP nutrition-related claims on fruit drinks purchased by households with young children and to examine the association between claims and the nutritional profile of fruit drinks. DESIGN: The sample included 2059 fruit drinks purchased by households with children 0 to 5 years old participating in Nielsen Homescan in 2017. FOP labels were obtained from 2 databases that contain bar code-level information on all printed material on product labels. A codebook was used to code for presence of FOP nutrition-related claims. The coded claims data were linked by bar code with Nutrition Facts label data. Claim type prevalence was calculated, and the association between claim types and median calories and total grams of sugar per 100 mL was analyzed using Wilcoxon rank-sum tests. The percentages of products containing noncaloric sweeteners (NCSs) with and without each claim type were also calculated and compared. RESULTS: Almost all (97%) fruit drinks sampled had at least 1 nutrition-related FOP claim. Implied natural claims such as "natural flavors" were the most common (55% of products), followed by claims about the presence of juice or nectar (49%). Claims about vitamin C (33%), sugar (29%), and calories (23%) were also common. Fruit drinks with vitamin C, juice or nectar, fruit or fruit flavor, and overt natural claims were higher in calories and sugar and less likely to contain NCSs compared with products without these claims. Fruit drinks with calorie, sugar, NCS, implied natural, and other claims were lower in calories and sugar and more likely to contain NCSs compared with products without these claims. CONCLUSIONS: Claims are prevalent on fruit drinks purchased by households with young children. This is concerning given prior research demonstrating that claims can mislead consumers. Regulatory actions such as requiring a warning or disclosure on drinks that contain added sugars or NCSs should be considered.

Protein Labelling Accuracy for UK Patients with PKU Following a Low Protein Diet.

A phenylalanine (protein)-restricted diet is the primary treatment for phenylketonuria (PKU). Patients are dependent on food protein labelling to successfully manage their condition. We evaluated the accuracy of protein labelling on packaged manufactured foods from supermarket websites for foods that may be eaten as part of a phenylalanine-restricted diet. Protein labelling information was evaluated for 462 food items ("free from", n = 159, regular, n = 303), divided into 16 food groups using supermarket website data. Data collection included protein content per portion/100 g when food was "as sold", "cooked" or "prepared"; cooking methods, and preparation instructions. Labelling errors affecting protein content were observed in every food group, with overall protein labelling unclear in 55% (n = 255/462) of foods. There was misleading, omitted, or erroneous (MOE) information in 43% (n = 68/159) of "free from" foods compared with 62% (n = 187/303) of regular foods, with fewer inaccuracies in "free from" food labelling (p = 0.007). Protein analysis was available for uncooked weight only but not cooked weight for 58% (n = 85/146) of foods; 4% (n = 17/462) had misleading protein content. There was a high rate of incomplete, misleading, or inaccurate data affecting the interpretation of the protein content of food items on supermarket websites. This could adversely affect metabolic control of patients with PKU and warrants serious consideration.

Uniformity of Food Protein Interpretation Amongst Dietitians for Patients with Phenylketonuria (PKU): 2020 UK National Consensus Statements.

In phenylketonuria (PKU), variable dietary advice provided by health professionals and social media leads to uncertainty for patients/caregivers reliant on accurate, evidence based dietary information. Over four years, 112 consensus statements concerning the allocation of foods in a low phenylalanine diet for PKU were developed by the British Inherited Metabolic Disease Dietitians Group (BIMDG-DG) from 34 PKU treatment centres, utilising 10 rounds of Delphi consultation to gain a majority (≥75%) decision. A mean of 29 UK dietitians (range: 18-40) and 18 treatment centres (range: 13-23) contributed in each round. Statements encompassed all foods/food groups divided into four categories based on defined protein/phenylalanine content: (1) foods high in protein/phenylalanine (best avoided); (2) foods allowed without restriction including fruit/vegetables containing phenylalanine ≤75 mg/100 g and most foods containing protein ≤0.5 g/100 g; (3) foods that should be calculated/weighed as an exchange food if they contain protein exchange ingredients (categorized into foods with a protein content of: >0.1 g/100 g (milk/plant milks only), >0.5 g/100 g (bread/pasta/cereal/flours), >1 g/100 g (cook-in/table-top sauces/dressings), >1.5 g/100 g (soya sauces)); and (4) fruit/vegetables containing phenylalanine >75 mg/100 g allocated as part of the protein/phenylalanine exchange system. These statements have been endorsed and translated into practical dietary management advice by the medical advisory dietitians for the National Society for PKU (NSPKU).

A Public Health Issue: Dietary Supplements Promoted for Brain Health and Cognitive Performance.

Background: Dietary supplements targeting brain health have quickly emerged in the marketplace as cognitive performance becomes an important public health issue. While manufacturers are required to report the exact ingredients and formulations listed on the Supplement Facts labels of products, many reports have indicated such labels are not always truthful, and the content of some products is inconsistent with the ingredients listed on the Supplement Facts label. Objectives: To identify dietary supplement products and ingredients marketed for brain health and cognitive performance and perform analyses of select products to verify whether purported claims are truthful and product labels accurate. Design: A scoping review was performed to identify products and ingredients. Products were selected for content analysis, investigated for scientific-sounding claims made, and assessed using an educational tool for potential red flags when reading Supplement Facts labels. Results: Twelve products were selected from the 650 products being marketed for brain health and queried about by Service Members. Eight (67%) had at least one ingredient listed on the Supplement Facts label not detected through analysis. Compounds not reported on the label were detected in 10 (83%) products. Scientific-sounding claims made are not supported by science and red flags are presented. Conclusions: There are dietary supplements targeting brain health being marketed to consumers that should be considered adulterated and misbranded. Advertisements and product labels may be deceiving and could put the public at risk. Education is required so that the public can recognize red flags while the U.S. Food and Drug Administration works to "modernize" the current regulations for dietary supplements.

Comparison of the Performance of Partial Least Squares and Support Vector Regressions for Predicting Fatty Acids and Fatty Acid Classes in Marine Oil Dietary Supplements by Using Vibrational Spectroscopic Data.

ABSTRACT: Simple, fast, and accurate analytical techniques for verifying the accuracy of label declarations for marine oil dietary supplements containing eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are required because of the increased consumption of these products. We recently developed broad-based partial least squares regression (PLS-R) models to quantify six fatty acids (FAs) and FA classes by using the spectroscopic data from a portable Fourier transform infrared (FTIR) device and a benchtop Fourier transform near infrared (FT-NIR) spectrometer. We developed an improved quantification method for these FAs and FA classes by incorporating a nonlinear calibration approach based on the machine learning technique support vector machines. For the two spectroscopic methods, high accuracy in prediction was indicated by low root mean square error of prediction and by correlation coefficients (R2) close to 1, indicating excellent model performance. The percent accuracy of the support vector regression (SV-R) model predicted values for EPA and DHA in the reference material was 90 to 110%. In comparison to PLS-R, SV-R accuracy for prediction of FA and FA class concentrations was up to 2.4 times higher for both ATR-FTIR and FT-NIR spectroscopic data. The SV-R models also provided closer agreement with the certified and reference values for the prediction of EPA and DHA in the reference standard. Based on our findings, the SV-R methods had superior accuracy and predictive quality for predicting the FA concentrations in marine oil dietary supplements. The combination of SV-R with ATR-FTIR and/or FT-NIR spectroscopic data can potentially be applied for the rapid screening of marine oil products to verify the accuracy of label declarations.

Inadequacy of nutrients and contaminants found in porridge-type complementary foods in Rwanda.

Child malnutrition remains persistently high in Rwanda. Complementary foods play a key role in young child nutrition. This study explores the quality and safety of complementary food products available in the Rwandan market. Ten of the most consumed porridge-type complementary food products in Rwanda have been analysed. Mean values of macronutrient and micronutrient contents were compared against three international standards and evaluated against label claims. Mean mycotoxin, microbiological, and pesticide contamination were compared with maximum tolerable limits. Mean energy density (385 kcal/100 g) and total fat content (7.9 g/100 g) were lower than all three international benchmarks. The mean fibre content of 8.5 g/100 g was above the maximum recommended amount of Codex Alimentarius and more than double the amount claimed on labels. Mean levels of vitamin A (retinyl palmitate, 0.54 mg/100 g) and vitamin E (α-tocopherol, 3.7 mg/100 g) fell significantly short of all three standards, whereas calcium and zinc requirements were only partially met. Average iron content was 12.1 mg/100 g. The analysis revealed a mean aflatoxin contamination of 61 µg/kg, and high mold and yeast infestation. Escherichia coli and pesticide residues were found, whereas no heavy metals could be quantitated. Overall, complementary food products in Rwanda show inadequate nutrient contents and high aflatoxin and microbial contamination levels. Improved regulation and monitoring of both local and imported products are needed to improve the quality and safety of complementary foods in Rwanda.

Compliance of declared vs. analysed values with EU tolerance limits for mandatory nutrients in prepacked foods.

This study assessed compliance between declared and analysed values on prepacked foods, considering the tolerance limits for salt, fat and saturated fatty acids. Foods were distributed by food categories (e.g. snacks, ready-to-eat meals, potato and potato-products, bakery and pastry products) and a total of 209 products were analysed. Only half of the samples with a declared value ≥1.25 g/100 g were within tolerance limits for salt content. The lowest number of samples outside tolerance limits was observed for fat content; for saturated fatty acids, 27% of the samples were outside of tolerance limits. Only amongst "cereal products" were 100% of products compliant for fat and salt declarations. It is of utmost importance that manufacturers update continuously values declared for prepacked foods, because this information is crucial for consumers and food policy-makers as well as being a legal requirement.

Plant-Based Meat Substitutes in the Flexitarian Age: An Audit of Products on Supermarket Shelves.

Demand for plant-based meat substitutes is growing globally for nutritional and environmental reasons, with Australia the third-fastest growing vegan market worldwide. This study aimed to profile and compare plant-based meat substitutes (mimicking meat) with equivalent meat products, and 2015 data. An audit undertaken in May (updated in September 2019) from four metropolitan Sydney supermarkets (Coles, Woolworths, Aldi, IGA), collected nutrition information and Health Star Rating (HSR) from 137 products (50 burgers, 10 mince, 29 sausages, 24 chicken, 9 seafood, 15 other). Mean (± standard deviation (SD)) and median (range) was calculated for nutrients and HSR. Plant-based options were generally lower in kilojoules, total and saturated fat, higher in carbohydrate, sugars, and dietary fibre compared with meat. Only 4% of products were low in sodium (58-1200 mg/100 g). Less than a quarter of products (24%) were fortified with vitamin B12, 20% with iron, and 18% with zinc. HSR featured on 46% (3.6-4.4 stars). On-pack claims were vegetarian/vegan/plant-based (80%), protein (63%), non-genetically modified/organic (34%), gluten free (28%). Product numbers increased five-fold (↑429%) in four years. The plant protein trend has prompted innovation in meat substitutes, however wide nutrient ranges and higher sodium levels highlights the importance of nutrition guidelines in their development to ensure equivalence with animal-based proteins.

Uncured-Labeled Meat Products Produced Using Plant-Derived Nitrates and Nitrites: Chemistry, Safety, and Regulatory Considerations.

Consumers often malign conventional curing agents while concomitantly accepting the natural forms of the same constituents in numerous food products. This paradox ostensibly exceeds all other food-related controversies to date and likely contributes to the rapid expansion of meat products that utilize natural nitrate derivatives. While there is high demand for these products, a fundamental lack of understanding regarding the safety and chemical implications of curing agents, whether derived from synthetic or natural sources, continues to persist. This manuscript elucidates the variations among curing preparations with particular emphasis pertaining to the associated safety, chemical, and regulatory ramifications encompassing these product categories.

Chemical Barcoding: A Nuclear-Magnetic-Resonance-Based Approach To Ensure the Quality and Safety of Natural Ingredients.

One of the greatest challenges facing the functional food and natural health product (NHP) industries is sourcing high-quality, functional, natural ingredients for their finished products. Unfortunately, the lack of ingredient standards, modernized analytical methodologies, and industry oversight creates the potential for low quality and, in some cases, deliberate adulteration of ingredients. By exploring a diverse library of NHPs provided by the independent certification organization ISURA, we demonstrated that nuclear magnetic resonance (NMR) spectroscopy provides an innovative solution to authenticate botanicals and warrant the quality and safety of processed foods and manufactured functional ingredients. Two-dimensional NMR experiments were shown to be a robust and reproducible approach to capture the content of complex chemical mixtures, while a binary normalization step allows for emphasizing the chemical diversity in each sample, and unsupervised statistical methodologies provide key advantages to classify, authenticate, and highlight the potential presence of additives and adulterants.

Commercially produced complementary foods in Bandung City, Indonesia, are often reported to be iron fortified but with less than recommended amounts or suboptimal forms of iron.

Commercially produced complementary foods (CPCF) that are iron fortified can help improve iron status of young children. We conducted a review of 217 CPCF sold in 42 stores in Bandung, Indonesia, in 2017. There were 95 (44%) infant cereals, 71 (33%) snacks or finger foods (biscuits or cookies, puffs, and noodles or crackers), 35 (16%) purees, and 16 (7%) other foods for which we obtained label information. Nearly 70% of CPCF reported iron content on their labels, but only 58% of products were reported to be fortified with iron according to ingredient lists. Among iron-fortified products, only one fifth indicated a specific type of iron used as the fortificant, but all of these were recommended by the World Health Organization for fortifying complementary foods. Infant cereal was more likely to contain added iron (81%) compared with snacks or finger food (58%) and purees (14%) and had higher iron content per median serving size (cereal = 3.8 mg, snacks or finger food = 1.3 mg, mixed meals = 2.7 mg, and purees = 0.9 mg). Infant cereal was most likely to meet the recommended daily intakes for iron (41% for infants 6-12 months of age and 66% for children 12-36 months) compared with snacks or finger food (infants = 14%, children = 22%), mixed meals (infants = 28%, children = 46%), or purees (infants = 9%, children = 15%). Regulations on fortification of complementary foods need to specify minimum levels and forms of iron and require reporting in relation to requirements by child age and serving size. Monitoring and enforcement of regulations will be essential to ensure compliance.

Comparison of Nutrient Reference Values for Food Labeling in Japan with CODEX Recommendations, Based on DRIs and Nutrient Intake in Japan.

To clarify the degree of consistency between the international recommendations and the national Japanese system, the nutrient reference values (NRVs) adopted by the CODEX were compared with current Japanese NRVs 2015, the dietary reference intakes for Japanese (DRIs-J) 2015, and actual nutrient intake levels by the Japanese population. The Japanese NRV for protein was high relative to CODEX NRV-R (i.e., NRV-Requirement). The Japanese NRVs for folate and calcium were low, and vitamin K was high, relative to each CODEX NRV-R. However, it was similar to the DRI-J values, and current intake levels for the Japanese population. For iron, calculation methods were different between the CODEX and Japan. Japanese iron NRV was calculated based on the RDA without menstruatating women, whereas CODEX NRV-R was calculated based on the INL98 of all adult men and women. Actual intake levels of iron for the Japanese population were similarly low. The Japanese NRV for sodium was high and potassium was low based on DRI-J values, relative to the CODEX NRV-NCD. For nutrients that show large discrepancies between the CODEX and Japanese NRVs, the values should be discussed further.

How effective is food industry self-substantiation of food-health relationships underpinning health claims on food labels in Australia?

OBJECTIVE: The Food Standards Code regulates health claims on Australian food labels. General-level health claims highlight food-health relationships, e.g. 'contains calcium for strong bones'. Food companies making claims must notify Food Standards Australia New Zealand (FSANZ) and certify that a systematic literature review (SLR) substantiating the food-health relationship has been conducted. There is no pre- or post-notification assessment of the SLR, potentially enabling the food industry to make claims based on poor-quality research. The present study assessed the rigour of self-substantiation. DESIGN: Food-health relationships notified to FSANZ were monitored monthly between 2013 and 2017. These relationships were assessed by scoping published literature. Where evidence was equivocal/insufficient, the relevant government food regulatory agency was asked to investigate. If not investigated, or the response was unsatisfactory, the project team conducted an independent SLR which was provided to the government agency. SETTING: Australia.ParticipantsSelf-substantiated food-health relationships. RESULTS: There were sixty-seven relationships notified by thirty-eight food companies. Of these, thirty-three relationships (52 %) from twenty companies were deemed to have sufficient published evidence. Four were excluded as they originated in New Zealand. Three relationships were removed before investigations were initiated. The project initiated twenty-seven food-health relationship investigations. Another six relationships were withdrawn, and three relationships were awaiting government assessment. CONCLUSIONS: To ensure that SLR underpinning food-health relationships are rigorous and reduce regulatory enforcement burden, pre-market approval of food-health relationships should be introduced. This will increase consumer and public health confidence in the regulatory process and prevent potentially misleading general-level health claims on food labels.

Claimed Effects, Outcome Variables and Methods of Measurement for Health Claims on Foods Related to Vision Proposed Under Regulation (EC) 1924/2006.

Adequate visual function has a strong impact on the quality of life of people. Several foods and food components have been hypothesized to play a role in the maintenance of normal visual function and in the prevention of eye diseases. Some of these foods/food components have been the object of a request of authorization for use of health claims under Articles 13(5) or 14 of the Regulation (EC) 1924/2006. Most of these requests have received a negative opinion from the European Food Safety Authority (EFSA) due to the choice of inappropriate outcome variables (OVs) and/or methods of measurement (MMs) applied in the studies used to substantiate the claims. This manuscript refers to the collection, collation and critical analysis of OVs and MMs related to vision. Guidance document and requests for authorization of health claims were used to collect OVs and MMs related to vision. A literature review was performed to critically analyse OVs and MMs, with the aim of defining their appropriateness in the context of a specific claimed effect related to vision. The results highlight the importance of adequate choices of OVs and MMs for an effective substantiation of claims related to visual function.

Development of functional agricultural products utilizing the new health claim labeling system in Japan.

In April 2015, Consumer Affairs Agency of Japan launched a new food labeling system known as "Foods with Function Claims (FFC)." Under this system, the food industry independently evaluates scientific evidence on foods and describes their functional properties. As of May 23, 2017, 1023 FFC containing 8 fresh foods have been launched. Meanwhile, to clarify the health-promoting effects of agricultural products, National Agriculture and Food Research Organization (NARO) implemented the "Research Project on Development of Agricultural Products" and demonstrated the risk reduction of osteoporosis of ß-cryptoxanthin rich Satsuma mandarins and the anti-allergic effect of the O-methylated catechin rich tea cultivar Benifuuki. These foods were subsequently released as FFC. Moreover, NARO elucidated the health-promoting effects of various functional agricultural products (ß-glucan rich barley, ß-conglycinin rich soybean, quercetin rich onion, etc.) and a healthy boxed lunch. This review focuses on new food labeling system or research examining functional aspects of agricultural products.

Dietary Supplement Ingredient Database (DSID) and the Application of Analytically Based Estimates of Ingredient Amount to Intake Calculations.

OBJECTIVE: We describe the purpose of the Dietary Supplement Ingredient Database (DSID), the statistical methodology underlying online calculators of analytically verified supplement content estimates, and the application and significance of DSID label adjustments in nutritional epidemiology. BACKGROUND AND HISTORY: During dietary supplement (DS) manufacturing, many ingredients are added at higher than declared label amounts, but overages are not standardized among manufacturers. As a result, researchers may underestimate nutrient intakes from DSs. The DSID provides statistical tools on the basis of the results of chemical analysis to convert label claims into analytically predicted ingredient amounts. These adjustments to labels are linked to DS products reported in NHANES. RATIONALE: Tables summarizing the numbers of NHANES DS products with ingredient overages and below label content show the importance of DSID adjustments to labels for accurate intake calculations. RECENT DEVELOPMENTS: We show the differences between analytically based estimates and labeled content for vitamin D, calcium, iodine, caffeine, and omega-3 (n-3) fatty acids and their potential impact on the accuracy of intake assessments in large surveys. Analytical overages >20% of label levels are predicted for several nutrients in 50-99% of multivitamin-mineral products (MVMs) reported in NHANES: for iodine and selenium in adult MVMs, for iodine and vitamins D and E in children's MVMs, and for iodine, chromium, and potassium in nonprescription prenatal MVMs. Predicted overages of 10-20% for calcium can be applied to most MVMs and overages >10% for folic acid in the vast majority of adult and children's MVMs. FUTURE DIRECTIONS: DSID studies are currently evaluating ingredient levels in prescription prenatal MVMs and levels of constituents in botanical DSs. CONCLUSIONS: We estimate that the majority of MVM products reported in NHANES have significant overages for several ingredients. It is important to account for nonlabeled additional nutrient exposure from DSs to better evaluate nutritional status in the United States.

Why Americans Need Information on Dietary Supplements.

Until a decade ago, no dietary supplement (DS) databases with open access for public use existed in the United States. They were needed by researchers, since half of American adults use dietary DSs and, without information on supplement use and composition, exposures could not be estimated. These articles on Challenges and Future Directions for Dietary Supplement Databases describe subsequent progress. They begin by describing why information on DSs is needed by the government and how it is used to ensure the health of the public. Current developments include: application of DS information to meet public health needs; research efforts on DS quality, efficacy, and safety (as conducted by the Office of Dietary Supplements and other federal agencies); enhanced regulatory activities implemented by the FDA Office of Dietary Supplement Programs, the FDA Office of Enforcement, and the Federal Trade Commission; and initiatives for broader development and dissemination of DS databases for commercial and public use. Other contributions in this journal supplement describe the challenges of working with DSs and the progress that has been made. Additional articles describe surveys of DS use among the general US population and also among special groups such as high supplement users, illustrating why there is a need in the United States for information on supplements. Likely directions for the future of DS science are summarized.
