Language：Japanese Publisher：The Japanese Society of Nutrition and Dietetics
<p><b>Objective:</b> To assess the feasibility of the draft Japanese Nutrient Profile (NP) model, we developed informational materials about its utilization, and conducted Internet research to identify issues and needs according to the motivation of behavioral change.</p><p><b>Methods:</b> We developed the informational materials (4 pages, 1 A3-sided sheet) based on the NP model, as well as materials from other countries. An online cross-sectional survey was conducted among 3,000 Japanese consumers aged 18 years or older. The age, sex, and regional distribution of the participants, as well as their motivation for behavioral change, were similar to those of the National census and the National Health and Nutrition survey, respectively. The participants read the informational materials and were asked how such materials would affect their food purchasing behavior. Based on the participants' current motivation for behavioral change, they were divided into three groups: not interested (<i>n</i> = 1,187), intend to improve (<i>n</i> = 1,465), and recognition of no problem with own eating behavior (<i>n</i> = 348).</p><p><b>Results:</b> More than 90% of the respondents found the informational materials easy to understand. The number of respondents who answered that the symbols that warned against overconsumption would influence their food purchasing behavior was greater for all food groups among the group with the intention to improve, accounting for approximately 70%, in contrast to only about 40% among those who were not motivated.</p><p><b>Conclusions:</b> Our results indicated that the food labeling based on the NP model might influence consumers' healthy eating behaviors, especially among those who intend to improve their eating behaviors.</p>

<p>A nutrient profile model (NP model) ranks foods according to their nutritional composition, allowing individuals to make well-informed dietary choices. In other countries, the application of NP models is reportedly associated with healthier food choices and health indicators. We examined a NP model applicable to the Japanese population for processed foods and preparing dishes. Considering the nutrition status of the Japanese population, we proposed that the model should target those aged 18 years or older. A category-specific model was adopted with setting thresholds to avoid overconsumption of total fat, saturated fat, sodium or salt equivalent, and energy for processed foods and prepared foods. We set the nutrient criteria for the proposed model and determined thresholds for each food category. In order to set the salt threshold for each dish, we conducted secondary analyses of the 2014‐2018 National Health and Nutrition Survey. The food groups according to dish type were compared between “high salt” consumers and “adequate” consumers. Furthermore, we conducted an online cross-sectional feasibility survey among 3,000 consumers. Here we describe the development procedure and feasibility of the proposed Japanese NP model to support the practice of healthy eating behavior.</p>

Language：Japanese Publisher：The Japanese Society of Nutrition and Dietetics
<p><b>Objective:</b> To increase awareness and dissemination of a nutrient profile model (NP model) in Japan, we analyzed data from consumers and identified issues they had.</p><p><b>Methods:</b> In February 2021, we conducted focus group interviews lasting roughly 2 hours with six groups of individuals according to age and sex. The age range was 18–74 years, and 36 individuals participated. Participants were individuals who purchased processed foods 2–3 times per week or more. Participants with specialized nutritional training or little desire to change their eating habits were excluded. Coding and categorization of data from the verbatim transcript and observational records were performed via content analysis.</p><p><b>Results:</b> Participants categorized the nutrition facts labels into "impractical to convert to individual serving amounts" and "I don't know what percentage or standard to use for daily intake." Participants favored NP model displays that clearly noted which nutrients were above the daily intake requirement, especially those that were color-coded and provided supplemental explanations. Many stated that while this did not influence their choice of their favorite foods, it did make them reconsider foods that were not favorites.</p><p><b>Conclusions:</b> For the NP model to support the practice of healthy eating habits among consumers, it is essential to offer immediate and clear notifications that are easy to understand. Consumer feedback indicated that the NP model notifications did not influence their choice of favorite foods. Therefore informational material to raise awareness of using the NP model should include dietary lifestyles.</p>

Language：Japanese Publisher：The Japanese Society of Nutrition and Dietetics
<p><b>Objective:</b> The selection of appropriate food groups is essential to promote a healthy diet. A nutrient profile model ranks foods according to their nutritional composition, allowing an individual to make well-informed dietary choices. Nutrient profile models have already been developed in other countries but not in Japan. Therefore, this study aimed to draft a nutritional profile model applicable to the Japanese population.</p><p><b>Methods:</b> A draft of a Japanese nutrient profile model for processed food was developed and validated using the World Health Organization (WHO) 2010 technical meeting report, WHO guiding principles and framework manual for front-of-pack labeling for promoting healthy diet in 2019, and models used in other countries. Data from the Japanese National Health and Nutrition Survey (NHNS), Dietary Reference Intakes for Japanese (2020), Standard Tables of Food Composition in Japan 2015 (7<sup>th</sup> revised edition), and Nikkei-POS database were used.</p><p><b>Results:</b> 1. Considering the nutrition status of the Japanese population, the target population age was set to 18 years or older, and the specific nutrients were total fat, saturated fat, sodium (salt equivalent), and energy. 2. A category-specific (threshold setting) model was selected, and the target foods included processed and prepared foods (ready-to-eat meals). Processed foods were further classified into 15 categories based on the Japanese NHNS. 3. The criteria for the Japanese nutrient profile model were determined and thresholds of the items were set to each food category.</p><p><b>Conclusions:</b> The draft of the Japanese nutrient profile model was developed according to the Japanese public nutrition status.</p>

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：The Japanese Society of Nutrition and Dietetics
<p><b>Objective:</b> "The collection of health hazard information from foods containing ingredients that require special attention" was established in an amendment of the Food Sanitation Act. The worsening of liver function indices is the most common serious health hazard caused by health foods that have been reported. From these backgrounds, safety research for health foods focusing on the hepatic effects is urgently needed. This study was conducted to search for health food ingredients that are predicted to cause health damage to the liver.</p><p><b>Methods:</b> Databases on health food materials, including "Handbook for materials of functional food" (book), "Information system on safety and effectiveness for health foods" (web; information from 2004 to July 2019), and "all of health foods and supplement's ingredients 2017" (book) were searched to extract information on the materials and ingredients of health foods that affected liver function indices and hepatic drug metabolism.</p><p><b>Results:</b> In total, 1,313 items of information on health food materials were obtained, of which 211 contained information about effects on liver function. The components contained in these 211 materials including tannin (26 cases), flavonoids (20 cases), saponins (11 cases), and so on, were superordinated. Of these 211 materials, 57 contained polyphenols.</p><p><b>Conclusions:</b> The effect of health food materials containing polyphenols on the liver was suggested. In the future, it would be necessary to study these effects in cell and animal experiments in order to estimate the cause-and-effect relationship between health food ingredients and their hepatic effects.</p>

<p><b>Objective:</b> Nutrient profile (NP) models, which classify or rank foods according to their nutritional composition, are commonly used as a nutrition policy in countries outside of Japan to evaluate the nutritional quality of foods. This study investigated the characteristics of NP models in other countries to determine the challenges that should be considered when developing a Japanese NP model.</p><p><b>Methods:</b> Using the available data on existing NP models, shared in the "Discussion paper on general guidelines to establish nutrient profiles for food labelling" from the agenda of the 41st session of the Codex Committee on Nutrition and Foods for Special Dietary Uses, target NP models (<i>n</i> = 97) were identified.</p><p><b>Results:</b> From the 97 models, 22 matched the inclusion criteria. These models were from Latin America (<i>n</i> = 1), North America (<i>n</i> = 5), Europe (<i>n</i> = 5), the Middle East (<i>n</i> = 1), Oceania (<i>n</i> = 2), Asia (<i>n</i> = 6), and international (regional offices of the WHO) (<i>n</i> = 2) sources. The models were developed for Front-of-Pack Labelling (<i>n</i> = 11), and regulation of health and nutrition claims (<i>n</i> = 5) were targeted to a general population, whereas the models developed to restrict marketing (<i>n</i> = 6) were targeted to a child population. Out of the 22 models, 16 used thresholds, five used scoring, and one used both. Most NP models were developed under the consideration that energy and some nutrients, such as fat, saturated fatty acids, trans fatty acids, sugars, and sodium should be limited.</p><p><b>Conclusion:</b> Developing the Japanese NP model will face challenges when determining targeted nutrients, food categories, and type of model.</p>

The Japanese Journal of Nutrition and Dietetics 78 ( Supplement ) S91 - S100 2020.12
Language：English Publisher：The Japanese Society of Nutrition and Dietetics
<p><b>Objective:</b> To review the regulatory system for nutrition labeling, especially for nutrient declaration, in Japan, and to highlight the contributions made by the National Institute of Health and Nutrition (NIHN) with regard to the reliability of nutrition labeling of food in recent years.</p><p><b>Methods:</b> We investigated the laws and official documents related to nutrition labeling of food in Japan, as well as relevant academic papers published by the NIHN from 1996 to 2020.</p><p><b>Results:</b> In Japan, under the Food Labeling Act, nutrient declaration of the five nutritional components, namely energy, protein, fat, carbohydrates, and salt equivalent, has been mandatory for all prepackaged processed foods since 2015. Declared nutritional values should be consistent with the values obtained by laboratory analysis in principle, but "the value obtained by reasonable estimate" is permitted under certain conditions. Laboratory analysis is indispensable for verifying the accuracy of label values of foods with nutrient content or health claims. The NIHN has contributed to the regulatory system of nutrition labeling from the following three standpoints: 1) legal inspection body for the Foods for Special Dietary Uses, including the Foods for Special Health Uses, (approval testing) and other prepackaged foods bearing nutrient declaration (compliance testing); 2) proficiency testing provision for organizations performing food nutrition analysis; and 3) research institute to develop and improve analytical methods for nutritional and functional components in foods.</p><p><b>Conclusions:</b> The NIHN has played pivotal roles in ensuring the reliability of nutrition labeling for more than half a century and will continue to do so in the future.</p>

Language：English Publisher：The Japanese Society of Nutrition and Dietetics
<p><b>Objective</b>: This article aimed to review the Japanese regulation of the food labelling systems for health and nutrition, and associated role of the National Institute of Health and Nutrition (NIHN).</p><p><b>Methods</b>: We investigated the development of standards and challenges associated with the Japanese regulation of food labelling system for health and nutrition. We also examined the contribution of the National Institute of Health and Nutrition to the development of the systems.</p><p><b>Results</b>: In 1991, the Ministry of Health and Welfare established the concept of Foods for Specified Health Uses (FOSHU), under the Nutrition Improvement Act. In 2001, the labelling system for vitamins and minerals was established under the Foods with Nutrient Function Claims regulations, and the Foods with Health Claims (FHC) system was set up with FOSHU. In 2015, the Foods with Function Claims classification was established under the Food Labelling Act by the Consumer Affairs Agency. Despite the regulated food labelling system in Japan, some "health foods" may have inappropriate use and labelling. The NIHN functions to (1) measure the amount of nutrients and ingredients in foods, ensuring accurate information on the labels for approval by the foods labelling system; (2) assesses safety and efficacy of health foods including FHC providing scientific evidences on their nutritional and physiological effects; and (3) provide reliable online information regarding health foods, the FHC and their labelling.</p><p><b>Conclusions</b>: The NIHN has an important role within the regulation systems of health foods including FHC system in Japan.</p>

<p>This paper deals with proficiency testing schemes for food nutrition analysis in Japan. In schemes in 2017 and 2018, 65 and 73 organizations participated, respectively, and more than 70% of the participants were public organizations responsible for a nutrition-labeling compliance test. The food matrices were pork and chicken sausages, and analytes were protein, fat, ash, moisture, carbohydrate, energy, sodium, salt equivalent, calcium (2018 only), and iron (2018 only). The organizations reporting inadequate laboratory values in one or more nutrients for mandatory declaration (energy, protein, fat, carbohydrate, or salt equivalent) were 11 and 15% of all organizations and 9 and 13% of public organizations in the 2017 and 2018 schemes, respectively. The approximate relative standard deviations for proficiency assessment (RSDr) were as follows: protein, 2%; fat, 3%; ash, 2%; moisture, 0.5%; carbohydrate, 9%; energy, 1%; sodium (salt equivalent), 4%; calcium, 7%; and iron, 7%. Notably, the large RSDr value for carbohydrate may cause inconsistency among laboratories in compliance tests for foods containing several grams or less of carbohydrate per 100 grams.</p>
