Although vegetarian gimbap was significantly more costly than the nonvegetarian gimbap, its cholesterol and saturated fat contents were significantly lower. Vegetarian rice balls had a significantly lower trans fat content than their nonvegetarian counterparts. Sandwiches in the vegetarian options had a significantly higher sugars content but had significantly lower protein and sodium contents than those in the nonvegetarian options. Vegetarian convenience foods did not meet one-third of the daily nutrient reference values for a single meal, similar to their nonvegetarian counterparts, but their sodium content exceeded the daily reference value. However, unlike the nonvegetarian options, the sodium content of vegetarian sandwiches did not exceed the daily value.Conclusion: Vegetarian convenience foods contain higher levels of carbohydrates and sugars and lower levels of protein, sodium, and cholesterol than nonvegetarian convenience foods. Foods such as vegetarian gimbap, rice balls, and sandwiches do not provide sufficient energy or nutrients to meet the nutritional requirements for a single meal. Creating nutritionally balanced vegetarian convenience foods should be the focus when developing new vegetarian food products.","PeriodicalId":72617,"journal":{"name":"Clinical nutrition research","volume":"15 1","pages":"36-44"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13007805/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147470472","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}

A 13-year-old female patient with morbid obesity complicated by nonalcoholic steatohepatitis (NASH), impaired glucose tolerance (IGT), and polycystic ovary syndrome (PCOS) underwent sleeve gastrectomy in July 2021. The patient achieved significant weight loss, with a total weight loss of 43.3% and a body mass index reduction of 16.6 kg/m2 at 3 years post-surgery, which further increased to 18.6 kg/m2 by the fourth year. Remission of NASH, IGT, and PCOS was observed after 1 year. Postoperatively, vitamin D deficiency developed, whereas other biochemical parameters remained within normal reference ranges. Adherence to recommended nutritional supplementation was suboptimal; however, with continuous nutritional education and regular follow-up, the patient ultimately established and maintained a balanced dietary pattern.

Conventional dietary interventions, such as the gluten-free, casein-free diet, typically fail to consider individual genetic variations. Nutrigenomics, the study of gene-nutrient interactions, offers a promising framework for exploring personalized dietary interventions that may help address the metabolic and neurological complexities associated with ASD, although current evidence remains preliminary. This research note offers recommendations for integrating nutrigenomics into special education through a multidisciplinary approach that combines clinical nutrition, genetics, and educational practice via a 3-phase agenda. Stage 1 focuses on identifying behavioral subgroups within special education settings and using validated tools such as the Child Behavior Checklist Scale to analyze nutritional intake. Stage 2 involves the development and pilot-testing of behavior-specific nutrition protocols that are tailored to these subgroups, incorporating input from practice experts in nutrigenomics. Lastly, in Stage 3, a personalized nutrition model that incorporates genetic screening and metabolic profiling is constructed in collaboration with dietitians, educators, and caregivers. By bridging clinical and educational domains, this study seeks to establish nutrigenomics-based nutrition therapy as a viable and equitable intervention for improving health and developmental outcomes among students with ASD.","PeriodicalId":72617,"journal":{"name":"Clinical nutrition research","volume":"14 4","pages":"329-337"},"PeriodicalIF":0.0,"publicationDate":"2025-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12629405/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145566321","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}

These wounds not only cause pain and reduce quality of life but also lead to prolonged hospitalization, increased risk of infection, and higher healthcare costs. Among the various contributing factors, malnutrition plays a crucial role by impairing collagen synthesis, weakening immune function, and delaying tissue repair. Adequate nutritional support-particularly sufficient protein and energy intake-is therefore an essential component of comprehensive pressure injury management. We present the case of a paraplegic patient who developed a vulvar pressure injury. A structured, stepwise nutritional intervention was implemented, including adjustment of meal composition based on appetite, supplementation with high-protein oral nutritional supplements, vitamins and minerals, and the use of probiotics to manage diarrhea. As a result, the patient's daily protein intake increased from less than 10 g to 80-90 g, accompanied by progressive wound improvement. Serial clinical assessments showed reduced slough, increased granulation tissue formation, and epithelialization. This case highlights the vital role of individualized nutritional management within a multidisciplinary approach to pressure injury care. Stepwise nutritional intervention, tailored to the patient's tolerance and clinical status, contributed significantly to wound healing. Nutritional optimization should be considered an integral component of effective pressure injury treatment strategies.","PeriodicalId":72617,"journal":{"name":"Clinical nutrition research","volume":"14 4","pages":"241-246"},"PeriodicalIF":0.0,"publicationDate":"2025-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12629406/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145566351","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}

Data were analyzed from 7,679 adolescents aged 12-18 years who participated in the 2007-2022 Korea National Health and Nutrition Examination Survey and completed health, examination, and nutrition surveys. Dietary intake was assessed using a 24-hour recall, and cluster analysis was performed based on the energy contribution of 26 food groups. Associations between dietary patterns and nutrient intake were examined using survey-weighted linear regression. Three dietary patterns were identified: Bread, Meat, & Dairy (33.1%); Rice-based Diet (45.5%); and Convenient Foods (21.3%). Among boys, the Rice-based Diet group showed the highest prevalence of obesity and the largest proportion of low-income households, whereas the Bread, Meat, & Dairy group exhibited higher rates of supplement use and high-income status (all p < 0.05). Among girls, the Convenient Foods group tended to be older and was more likely to skip breakfast, consume alcohol, eat out daily, and perceive themselves as overweight (all p < 0.05). Over the 16-year period, adherence to the Bread, Meat, & Dairy pattern increased, whereas adherence to the Rice-based Diet pattern declined in both sexes (p < 0.01). These findings highlight a shift toward Westernized dietary patterns among Korean adolescents. Accordingly, nutrition policies and interventions should adopt tailored strategies that account for both sex and socioeconomic differences to promote healthier eating habits and support long-term adolescent health.","PeriodicalId":72617,"journal":{"name":"Clinical nutrition research","volume":"14 4","pages":"270-283"},"PeriodicalIF":0.0,"publicationDate":"2025-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12629410/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145566371","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}

Relevant studies published between 2015 and 2024 were identified through comprehensive searches of PubMed and the Cochrane Library using keywords including \"MIND diet,\" \"cognitive performance,\" and \"older adults.\" From a total of 138 records screened, 11 studies met the inclusion criteria after excluding reviews, meta-analyses, editorials, and those incorporating other lifestyle interventions such as physical activity or education. These studies included 7 prospective cohort studies, 2 cross-sectional studies, 1 randomized controlled trial (RCT), and 1 case-control study, comprising a total of 17,201 participants aged 57-91 years. Across studies, at least 57% of participants were women, and in the 5 studies reporting race, more than 75% were White. Dietary intake and MIND adherence were assessed primarily via food frequency questionnaires, while cognitive outcomes were evaluated using validated instruments including the Montreal Cognitive Assessment, global cognition scores, Consortium to Establish a Registry for Alzheimer's Disease tests, and magnetic resonance imaging. Six cohort and two cross-sectional studies reported significant associations between higher MIND adherence and better cognitive outcomes. One cohort study and the single RCT showed no effect.

The mean PhA declined from 5.57° in participants aged 20-39 to 4.23° in those aged 80+, corresponding with decreases in height and weight. Individuals with higher PhA exhibited significantly greater lean body mass and lower body fat; for example, among those aged 20-39, the high PhA group showed 56.02 kg of lean mass versus 40.71 kg in the low group (p < 0.001) and total body water of 41.07 L versus 29.84 L (p < 0.001). Regarding metabolic diseases, 35.2% of the high PhA group aged 20-39 had grade 1 obesity compared with 17.4% in the low group, with similar associations observed for diabetes and hypertension across age groups. Nutritional intake was also higher in the high PhA group, with mean energy intake of 2,180.84 versus 1,710.16 kcal (p < 0.001).
