The personalized meal service is being developed to prevent and alleviate illnesses according to the individual's health condition. However, the current meal does not provide a fully customized service to individuals and a diet that meets the consumer's information needs. The cause is the lack of information on the ingredients and the difficulty of comparative analysis between the materials. Therefore, in this study, we propose basic analysis process for basic information acquisition and database construction for food composition before providing personalized food. In this study, we investigated the content of carbohydrate, reducing sugar and protein as basic components of Grifola frondosa and investigate the content of polyphenol as a biological active ingredients. Respectively. Studies on the hypoglycemic effect of the diabetic rat model have been carried out in relation to the prevention of diseases. Based on the results of this study, it is also possible to obtain information on the basic ingredients of the food and to analyze the information on the content and activity of the biological active ingredients. Using animal models, information on disease prevention and mitigation was also available. The process introduced in this study is applied to various food materials, accumulating data, and utilizing Database, this results will be an excellent tool for providing more efficient service by providing a proper dietary composition for consumers.

This study aims to understand the influence of COVID-19 on youth daily life by analyzing the correlation between youth health and diet according to whether economic status has changed due to COVID-19 and to provide basic data on program construction for the welfare of socially marginalized adolescents. As a result of the study, the proportion of respondents who answered that there was a change in economic status at a high rate for decreased academic performance (p<0.001), stress perception, and suicidal thoughts (p<0.001), and the proportion of decreased number of breakfasts and increased fast food consumption (p<0.001) was also high. These results of the study are thought to be the reason for the increase in adolescents who are alienated due to changes in home conditions due to COVID-19, which is expected to affect the physical and mental health of adolescents who lack communication and guidance, and the increase in delinquents rate due to reduced academic concentration and increased junk food intake. Therefore, through this study, it can be helpful to use basic data for the development of welfare programs such as non-face-to-face as basic data for teenagers alienated from COVID-19.

Purpose: Dysphagia, vomiting and feeding difficulties are common symptoms, with which children present. Esophageal function testing with high resolution manometry can help in diagnosing and treating these patients. We aim to access the clinical utility of high-resolution manometry of esophagus in symptomatic pediatric patients. Methods: A retrospective chart review was done on all symptomatic patients who underwent esophageal high-resolution manometry between 2010 and 2019 at Sydney Children's Hospital, Australia. Manometry results were categorized based on Chicago classification. Demographic data, indication of procedure, manometric findings, and details of treatment changes were obtained and analyzed. Results: There were 62 patients with median age of 10 years (9 months-18 years). The main indication for the procedure was dysphagia (56%). Thirty-two percent of patients had a co-morbid condition, with esophageal atresia accounting for 16%. The majority (77%) of patients had abnormal manometry which included, ineffective esophageal motility in 45.2%. In esophageal atresia cohort, esophageal pressurization was seen in 50%, aperistalsis in 40% and 10% with prior fundoplication had esophago-gastric junction obstruction. Patients with esophago-gastric junction obstruction or achalasia were treated by either pneumatic dilation or Heller's myotomy. Patients with ineffective esophageal motility and rumination were treated with a trial of prokinetics/dietary texture modification and diaphragmatic breathing. Conclusion: Esophageal high-resolution manometry has a role in the evaluation of symptomatic pediatric patients. The majority of our patients had abnormal results which led to change in treatments, with either medication, surgery and/or feeding modification with resultant improvement in symptoms.

BACKGROUND/OBJECTIVES: School food service has played an important role in promoting the health and physical condition of students by providing students with a balanced and nutritious diet. Therefore, boosting the quality of school food service and improving the students' satisfaction is critical. For this purpose, this study examined the structural causal relationship among the quality of school food service factors, emotional responses, and satisfaction in China. SUBJECTS/METHODS: This study was conducted with 4th-6th-grade students from 6 junior high schools in Henan province of China, with 590 questionnaire responses (87.3%) collected and statistically analyzed. RESULTS: The school food service quality factors (including menu management, dietary education, facilities management, price and food distribution management, and personal hygiene during meals) must be enhanced to boost the students' satisfaction. In addition, the study used questionnaire survey data to validate the full mediation of students' emotional responses between school food service quality factors and student satisfaction. CONCLUSIONS: Students' emotions also play an important role in influencing the quality of school food service, all of which affect the emotional responses of students. Therefore, students' positive emotions are an important indicator for improving the quality of school food service. A national support policy is necessary for the ongoing maintenance and development of various programs that drive students' satisfaction and promote the adoption of education guidelines for school food service in China.

This study was conducted to analyze relationships between depression indices, mini nutritional assessment scores, and nutritional quotients among 80 elderly in Yangpyeong-gun and to identify factors that help prevent depression and malnutrition. Nutrition assessment scores were low in the high-risk group (PHQ-9 score ≥10), and nutritional quotient scores were lower in the high-risk group than in the normal group (PHQ-9 score ≤4). Interestingly, the consumption frequencies of fruits, eggs, and nuts were low in the high-risk group, and subjective health awareness, dental condition, and sleep were poorer. The total PHQ-9 score was correlated with malnutrition, body mass index, calf circumference, weight change, independent daily living, reduced meal amount, water intake, and the need for help when eating. Analysis of correlations between items of the PHQ-9 and nutritional status evaluation indices showed that a self-perceived feeling of depression, low energy, difficulty controlling sleep or appetite, negative thoughts (e.g., failure, disappointment), and difficulty concentrating were negatively correlated with total nutritional status scores. These results show that attention is required when food or water intake decreases and that deviation from normal sleep and appetite cycles flags the need to prepare guidelines to prevent depression.

In recent years, the number of patients with benign prostatic hyperplasia (BPH), a condition that commonly occurs in elderly men, has increased due to aging and the adoption of western dietary habits. Treatment with chemical drugs, such as finasteride or dutasteride, can cause side effects such as erectile dysfunction or sexual problems. This necessitates the development of remedies using natural substances derived from food ingredients. In this study, we investigated the inhibitory effects of Oxya chinensis sinuosa hot water extract (OCH) on BPH production in LNCaP cells, a hormone-dependent prostate cancer cell line. We found that the mRNA expression of androgen receptor (AR), prostate specific antigen (PSA), and, 5α-reductases 1, and 2 decreased following treatment with OCH. Furthermore, OCH treatment resulted in reduced protein expression of BPH regulators, such as AR. Collectively, these results suggest that OCH exerts a beneficial effect on BPH by inhibiting the AR signaling pathway, indicating the potential of OCH as a therapeutic agent for the prevention and treatment of BPH.

Brain plasticity refers to the brain's ability to modify its structure, accompanied by its functional changes. It is influenced by learning, experiences, and dietary factors, even in later life. Accumulated researches have indicated that ginseng may protect the brain and enhance its function in pathological conditions. There is a compelling need for a more comprehensive understanding of ginseng's role in the physiological condition because many individuals without specific diseases seek to improve their health by incorporating ginseng into their routines. This review aims to deepen our understanding of how ginseng affects brain plasticity of people undergoing normal aging process. We provided a summary of studies that reported the impact of ginseng on brain plasticity and related factors in human clinical studies. Furthermore, we explored researches focused on the molecular mechanisms underpinning the influence of ginseng on brain plasticity and factors contributing to brain plasticity. Evidences indicate that ginseng has the potential to enhance brain plasticity in the context of normal aging by mediating both central and peripheral systems, thereby expecting to improve age-related declines in brain function. Moreover, given modern western diet can damage neuroplasticity in the long term, ginseng can be a beneficial supplement for better brain health.

Recent studies described the ${\varepsilon}4$ allele of apoE confers a two-to fourfold increased risk for late-onset Alzheimer#s disease (LOAD), but LOAD pathology does not all fit neatly around apo E. Therefore, the goal of this study was to find the association between Alzheimer and apo E4 genotype in the 107 elderly between 50 to 64 years old who visited to FHWC of Sungshin Women#s University. We conducted the questionnaire survey (general & 24 hr dietary recall), anthropometerics (BP, waist & BMI) and blood biochemistry (FBS & lipid profiles). LDL-c and HOMA-IR were calculated by Friedwald#s and Matthew#s formulas. The apo E genotyping was performed by PCR-RFLP method and subjects were divided into three allele groups (${\varepsilon}3$; wild, ${\varepsilon}2$ & ${\varepsilon}4;$ mutants). The apo E allele frequencies were 7.0% for the ${\varepsilon}2$, 83.6% for the ${\varepsilon}3$ and 9.3% for the ${\varepsilon}4$. In comparison with biochemistry characteristics by apo E genotype, FBS was significantly higher in ${\varepsilon}4(129.2{\pm}6.8)$ than that in the others (${\varepsilon}2$: $117{\pm}7.4$, ${\varepsilon}3$: $107.3{\pm}2.2)$ (p<0.01). More than forty percents of ${\varepsilon}4$ group shown the dyslipidemia [high TG (>150mg/dl) & low HDL (<40 mg/dl:male or <50 mg/dl: female)]. The cytokines levels such as IL-1 ${\beta}$, IL-6 and $TNF-{\alpha}$ were not different among three apoE alleles. After the adjusting sex, age & dietary fiber, LDL-c level was siginificantly higher in ${\varepsilon}4$ ($108.3{\pm}7.7$) than that in ${\varepsilon}2$ ($100.4{\pm}8.4$) (p<0.05). According to food intake and the recipe on the basis of 24 hr dietary recall, the elder]y with ${\varepsilon}4$ allele took higher intake frequency of the light -colored vegetable (radish, onion & cabbage) and pan-fried foods (sauteed beef and vegetables, stir-fried vienna with vegetables) than the others. We knew that the elderly with ${\varepsilon}4$ allele had been restricted the calories intakes with high dietary fiber (33.6+2.5 g/d) to maintain the normal level of FBS and LDL-c. On next study, the prevalence of Alzheimer#s disease in this population who has ${\varepsilon}4$ allele on the condition of calories restriction will be continually follow-up.

Oxygen consumption (OC), ammonia nitrogen (AN ) excretion and body composition were measured to study the effects of energy/protein ratio (EPR) on the utilization of protein and energy in juvenile rockfish, Sebastes schiegeli. Juvenile rockfish were divided into three groups that they fed three isocaloric diets (3,5kcal/g) containing 30 (I), 40 (II) or $50\%$ crude protein (III). EPR of the three experimental diets were 11.5 (I), 8.7 (II) and 7.0kcal/g III), respectively. Juvenile rockfish (wet wt. 2.9-3.1g) were cultured in 501 aquaria with the constant environmental condition of $20-24^{\circ}C$ water temperature and $34\%o$ salinity. For 24 hr after feeding the diets, juvenile rockfish fed diet III had a higher OC than did the fish from groups fed diets I and II, and average OC of the fish fed diets I, II and III were $0,93\pm0.02^a,\;0.92\pm0.02^a\;and\;1.03\pm0.03^bml\;O_2/g/h$, respectively. AN responses of juvenile rockfish to increasing levels of dietary protein (decreasing dietary EPR) were significantly different among three groups in which dietary protein at elevated levels increased the excretion of AN for 24 hr after feeding the diets. Average AN excretion of the fish fed diets I, II and III were $9.14\pm0.39^a,\;12.41\pm 0.53^a\;and\;14.89\pm0.55^c\;{\mu}g\;N/g/h$ respectively. The body protein content of the fish fed diet II for 59 days was significantly higher than that of the fish fed the other diets. But, there were no significant differences between three groups in body lipid, carbohydrate and ash contents. These results indicate that EPR of 9.7kcal/g (diet II) could be a optimum EPR in juvenile rockfish diet.

The purpose of this study was to assess the relationship that adolescent stress perception level has with dietary habits and oral health behaviors in high school students. A survey of high school students in some areas of the Jeollabuk-do province of South Korea was conducted. Five hundred fourteen survey responses were used in the final analysis. As a result of the questionnaire survey, the following conclusions were obtained. The highest stress type was indicated to be academic stress (mean${\pm}$standard deviation [SD], $3.09{\pm}0.89$). The next was shown to be home (family) stress (mean${\pm}$SD, $2.85{\pm}0.84$). The possibility of using a dental clinic was indicated to be less in girls than boys (p<0.001). Regarding subjective oral health behavior, the possibility of visiting a dental clinic was low in those who thought that their own oral health condition was not good or moderate (p<0.05). Also, it was shown that the higher stress led to the higher possibility of visiting a dental clinic (p<0.01). Students with higher grades had a in the upper ranks were indicated to have high possibility of having a regular meal (p<0.01). Higher stress led to the significantly higher possibility of eating cariogenic food (p<0.01). Students with median grades had a high possibility of eating cariogenic food (p<0.01), while students with higher grades had a low possibility of eating cariogenic food (p<0.05). These resultss show that stress perception level influences dietary habits and oral health behaviors. Thus, there is a need to develop a program in high scholls to promote the physical and mental health of students to relieve stress. Substantial and systematic oral health education is thought to be likely needed to develop desirable dietary habits.
