Therefore, we investigated the relationship between serum 25-hydroxyvitamin D [25(OH)D] concentration and atherosclerotic disease risk factors in healthy Japanese adults. In the present cross-sectional study, 1,177 subjects (348 males and 829 females) aged 20-72 y living in Japan (34.7-35.0ºN) were evaluated for vitamin D status by measuring serum 25(OH)D concentration. Atherosclerotic disease risk factors were defined as the presence of two or more of the following three risk factors: high blood pressure, dyslipidemia, and hyperglycemia. The percentages of vitamin D deficient and insufficient subjects were 33% and 46% in males and 59% and 32% in females, respectively. Subjects with atherosclerotic disease risk factors were significantly older and had higher BMI than those without it in both sexes. Male subjects with atherosclerotic disease risk factors had significantly lower physical activity and serum 25(OH)D concentration than those without it. In a logistic regression analysis adjusted for confounding factors, serum 25(OH)D concentration showed a significant inverse association with risk factors of atherosclerotic disease in males (OR=0.951, 95%CI: 0.906-0.998), but not in females. A covariance structure analysis also suggested that serum 25(OH)D level has a direct association with risk factors of atherosclerotic disease. In conclusion, we have demonstrated that low serum 25(OH)D level is a significant factor for increased atherosclerotic disease risk factors in males.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"69 3","pages":"176-183"},"PeriodicalIF":1.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9779036","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}

Appropriate nutritional guidance for CMA children is therefore needed. The purpose of this study was to conduct a dietary survey of CMA children and to compare their characteristics according to the degree of elimination. A dietary survey of FA children attending the allergy clinic at Shiga Medical Center for Children, Shiga, Japan, was conducted using the brief-type self-administered diet history questionnaire for Japanese children and adolescents (BDHQ15y). To objectively assess the intake of fruit and vegetables, skin carotenoid levels were measured using the Veggie Meter®. Regarding the degree of CM elimination, of the 147 FA children (89 boys, 58 girls) recruited, 38, 27, and 82 children were allocated to complete-, partial-, and non-elimination groups, respectively. In analyzing the data, boys and girls were combined because there was no difference in sex ratio among the groups. Significantly lower intakes of calcium, animal proteins, and vitamin B2 were observed with increasing degree of CM elimination. Conversely, significantly greater intakes of vegetable proteins, β carotene, α tocopherol, vitamin C, and polyunsaturated fatty acids, as well as significantly higher levels of skin carotenoids, were observed with increasing degree of CM elimination. Intakes of many nutrients with antioxidant and anti-inflammatory effects were higher with increasing degree of CM elimination, presumably reflecting the efforts of caregivers in identifying alternative foods. However, calcium intake was still inadequate, indicating a need for further encouragement of calcium intake in CMA children.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"69 4","pages":"275-283"},"PeriodicalIF":1.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10127444","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}

Information regarding medical history and lifestyle factors was obtained by a self-administered questionnaire, while hours of sun exposure were determined through interviews. Dietary intake of vitamin D was evaluated using a validated food frequency questionnaire. Fasting plasma glucose and insulin concentrations were measured, and insulin resistance (HOMA-IR) scores were calculated based on homeostasis model assessment. Women with vitamin D deficiency (25(OH)D<20 ng/mL) had significantly higher fasting plasma insulin concentration and HOMA-IR than did the other women. Plasma 25(OH)D concentration was significantly and inversely associated with fasting plasma insulin level and HOMA-IR after controlling for age, season, menopausal status, BMI, smoking status, alcohol intake, physical exercise, and intakes of fat and calcium. Dietary vitamin D intake was not associated with HOMA-IR concentration after adjusting for these covariates and hours of sun exposure. Although significant inverse association between plasma 25(OH)D concentration and HOMA-IR was observed in women with a low BMI, low fat intake, or a high calcium intake, the interaction terms were not statistically significant.

Data were obtained for Australia, Canada, Ireland, Japan, the UK, the US, and the European Food Safety Authority (EFSA), where information was accessible online in English or Japanese. We collected the following information regarding sodium intake: the term used for reference values to prevent NCDs; year when reference values were established or revised; reference values to prevent NCDs; target NCDs; designation of nutrition survey; method for estimating intake; and average intake. The reference values ranged from 2,000 mg (Australia and EFSA) to 2,953 mg (Japan). Sodium intake ranged from 2,431 mg (Australia) to 3,958 mg (Japan). Out of seven countries/institutions, five used dietary assessment, and two used sodium urinary excretion for estimating dietary sodium intake. Among the dietary assessment methods, the 24-h dietary recall was most frequently used. National sodium intake exceeded the reference values in all countries, and reduction of sodium intake remains a global challenge.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"69 1","pages":"38-45"},"PeriodicalIF":1.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10823779","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}

Recent studies have reported that FA intake significantly suppresses body weight gain and accumulation of fat deposits in mice. However, the mechanism by which FA intake affects body fat accumulation remains unclear. We hypothesized that dietary FA induces the formation of beige adipocytes and contributes to the suppression of body fat accumulation. In this study, we investigated whether dietary FA significantly induces beige adipocyte formation and thermogenesis in mice. We found that intake of dietary FA (control diet supplemented with 10 g of FA/kg diet) for 4 wk significantly decreased white adipose tissue (WAT) deposits and body weight gain and significantly induced beige adipocyte formation in inguinal WAT (iWAT) in mice. Furthermore, dietary FA specifically induced thermogenesis in iWAT, dependent upon the significant induction of uncoupling protein 1 expression. These findings suggest that the dietary FA-mediated reduction of WAT accumulation and body weight gain is associated with the induction of beige adipocyte formation and thermogenesis in iWAT, which increases energy expenditure. Our study presents a novel example of dietary FA intake-mediated bioactivity as a functional food-derived factor.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"69 5","pages":"377-381"},"PeriodicalIF":1.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71521767","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}
