However, the composition of amino acids and fatty acids varies depending on the food source, requiring detailed analysis for accurate dietary assessment. Currently, limited research exists on the detailed composition of foods commonly consumed in Japan. Therefore, we aimed to compare the characteristics of amino acid and fatty acid in foods that are the major sources of protein in the Japanese diet. Data cleaning was performed on 2,478 foods listed in the Food Composition Table 2020 (8th revision). Heatmap cluster analysis was performed for food groups, amino acid, and fatty acid, and statistical analysis was performed to determine the percentage differences between food groups. Heat map cluster analysis of the fish and meat data showed that the foods were divided into two groups in the first level (fish and meat). Characteristic amino acid and fatty acid were 5/8 for meat, 1/27 for fish, and 13/0 for common, and no common fatty acid were noted. Significant differences were found between nine amino acids and 31 fatty acids. Heat map cluster analysis using data on seafood, meat, legumes, and eggs showed that foods could be classified into two clusters at the first level: seafood and meat, with legumes and eggs included in the meat cluster. The results of the heat map cluster analysis using statistical analysis and means indicated that seafood, meat, and legumes were characterized differently, especially in terms of fatty acid.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"71 3","pages":"211-222"},"PeriodicalIF":0.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144528392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are few studies on the PK content of algae and its correlation with chlorophyll content. To evaluate the PK content in algae and its correlation with chlorophyll, the PK and chlorophyll contents in algae, including Phaeophyta (18 species), Rhodophyta (17 species), and Chlorophyta (seven species), were determined. Algae, particularly Phaeophyta, contain more functional components than do other green terrestrial plants. Therefore, other components such as carotenoids, polyphenols, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging ability were analyzed to confirm their correlation with PK. Furthermore, terrestrial plants such as leafy vegetables, other vegetables, and tea powder were evaluated for the same components and compared with the experimental results for algae. This results showed that PK was abundant in Phaeophyta and almost all samples contained more than 100 μg/100 g of dry samples. In particular, Sargassum muticum contained 514.11±11.29 μg/100 g. However, almost all of the Rhodophyta and Chlorophyta contained a little PK. The results also confirmed a positive correlation between the PK and chlorophyll content in Rhodophyta (R2=0.7085), Chlorophyta (R2=0.7264), and terrestrial plants (R2=0.8436). However, no correlation was observed between the PK and chlorophyll content in Phaeophyta (R2=0.1013). In addition, the principal component analysis results showed no correlation between PK and other components, such as carotenoids and polyphenols, and DPPH radical scavenging ability in algae.

Among 583 men, CAD was found in 404, of whom 137 had myocardial infarction (MI). The prevalence of CAD and MI stepwisely decreased on alcohol intake: 80% and 30% in nondrinkers, 65% and 20% in light, 60% and 17% in moderate, and 54% and 16% in heavy drinkers (p<0.001).

In this study, 4,006 plant extracts were evaluated for FoxO1 and FoxO3a inhibitory activity using a reporter gene assay system, and the extracts from Cephalotaxus harringtonia showed potent inhibitory activities. These extracts also suppressed dexamethasone-induced expression of FoxO target genes, such as atrogin-1 and cathepsin L in C2C12 myotubes. Furthermore, harringtonine alkaloids, harringtonine and homoharringtonine, contained in Cephalotaxus harringtonia inhibited FoxOs activities and suppressed dexamethasone-induced expression of FoxO target genes in C2C12 myotubes, suggesting that harringtonine alkaloids contributed to the effects observed in C2C12 myotubes treated with Cephalotaxus harringtonia extract.

We analysed the association between eating situations, meal greetings, pleasant mealtime, states of mastication, eating speed, and behavioural problems among preschool children. In these analyses, a Total Difficulty Score (TDS) was used to classify children's behavioural characteristics into two groups, 'Normal' and 'Borderline/Abnormal,' and binomial logistic regression analysis was performed. We calculated the odds ratio (OR) and 95% confidence interval (95% CI) for 'Borderline/Abnormal.' Children who rarely ate breakfast with their families had an adjusted OR of 10.59 for borderline/abnormal TDS compared to children who ate breakfast with their families four or more days a week (p=0.005). Children who chewed only a little at meals had an adjusted OR of 3.25 for borderline/abnormal TDS than children who chewed well. Furthermore, the children who answered that mealtimes were not pleasant mealtime had an adjusted OR of 3.01 for borderline/abnormal TDS than children who always had pleasant mealtime.
