During pandemic, with increased interest in information about healthy food choices and optimum nutrition, frequent exposure to NFLs on pre-packaged foods and dietary supplements may have helped consumers become aware of and/or use NFLs. We aimed to evaluate NFL usage changes from the pre- and early to the late pandemic years in the Korean adult population, using data from the Korean Community Health Survey (3-year total respondents n = 687,610) conducted from 2019 to 2021. NFL awareness, effect, and utilization ratios in each subgroup (sex, age, diabetes mellitus/hypertension, subjective health status, and physical activity) were analyzed for the 3 years by the cross-tabulation test of weighted complex sample analysis. Despite the declining awareness of NFLs in the Korean population, the proportion of individuals who were affected by the NFL content in the entire population and the utilization ratio among those who were aware of NFLs increased continuously during the early and late pandemic periods. Thus, Nutrition experts and policy-makers need to increase efforts to maintain interest in NFLs that emerged during the pandemic. NFLs, a conventional but well-regulated and effective tool, may have enabled the Korean population to make healthy food choices during the pandemic.","PeriodicalId":72617,"journal":{"name":"Clinical nutrition research","volume":"13 4","pages":"257-271"},"PeriodicalIF":0.0,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11543451/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142633356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Korean food exchange lists were first developed in 1988, revised in 1995, and updated again in 2010. With rapidly changing dietary habits and increasing demand for diverse food cultures, the Korean Diabetes Association in cooperation with 4 related organizations established a Task Force Team (TFT) to revise food exchange lists in March 2022. Starting with a workshop, TFT held 11 official revision meetings, culminating in a public hearing in May 2023. The final revised version of Korean food exchange lists was published in December 2023. Key outcomes of the revision are summarized as follows: 1. Based on the National Standard Food Composition Table 10.0 database, the existing classification system and nutrient standards for each food group remain unchanged this time. 2. Based on a survey conducted among diabetes educators, the number of items on the food exchange lists has increased from 339 in 2010 to 435 this time. 3. Considering patients' usual eating habits, meal planning examples were developed distributing food group exchange units by energy level based on 3 types of proportions of carbohydrate energy (40%-45%, 50%-55%, 60%-65%). 4. Due to limitations in real-time updates for rapidly changing information, detailed guidance on how to access and interpret the data is provided. These revisions will help people with diabetes manage their blood sugar levels and facilitate the implementation of healthy meal planning in various other conditions, including obesity.","PeriodicalId":72617,"journal":{"name":"Clinical nutrition research","volume":"13 4","pages":"227-237"},"PeriodicalIF":0.0,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11543450/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142633371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This case report aimed to demonstrate nutritional evaluation, education, and counseling for a male patient with chronic kidney disease (CKD) who underwent BS one year after surgery. Following BS, the patient adhered to the standard Seoul National University Hospital BS diet protocol. Considering his postoperative renal function, protein requirement was set at 1.0 g/kg of IBW.

One year after BS, he successfully lost weight with % excess weight loss of 93%, maintained CKD stage 3, reduced prescription of oral hypoglycemic agent, improved glycated hemoglobin levels, and improved eating habits significantly.

This review specifically focuses on studying the effects of healthy diet interaction and MC4R polymorphisms on the development of CVD. The quantity and quality of carbohydrates and proteins consumed are related to obesity susceptibility and cardiometabolic risk factors. A healthy dietary pattern such as a Mediterranean dietary can modulate the association between MC4R polymorphisms (rs17782313) and the risk of CVDs. Also, the Nordic diet can reduce lipid profiles such as low-density lipoprotein cholesterol (LDL-C) and total cholesterol levels. On the other hand, MC4R interaction with the dietary inflammatory index decreases high-density lipoprotein cholesterol levels and increases LDL-C and triglyceride (TG) levels. Additionally, the DASH diet decreases TG, atherogenic index of plasma, systolic blood pressure, diastolic blood pressure, and serum glucose. The interaction between MC4R genes and diets plays an important role in the development of CVD. Adherence to healthy diets such as the Mediterranean, Nordic, Anti-inflammatory, and Dash diets might be an efficient strategy to prevent CVD. The potential for personalized diets to be developed for the treatment and prevention of CVD and its related comorbidities is expected to expand as this field develops.","PeriodicalId":72617,"journal":{"name":"Clinical nutrition research","volume":"13 3","pages":"214-225"},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11333145/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142010046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
