Previously, we reported that short-term stress sharpens the sense of taste and dulls the sense of pungency, but in this study, we examined the effects of chronic mental stress on taste and pungency by comparing normal days with end-of-semester examination days. Furthermore, the relationship between pungency measured on the tongue and the corresponding skin current value causing forearm pain was investigated. Taste and pungency were blindly measured using the filter paper disc method on a normal day and the day before the end-of-semester examination (chronic mental stress day) in 27 healthy male university students. A commercially available taste liquid for taste testing and a capsaicin solution for pungency were used. Taste perception was also tested using cognitive thresholds, and pungency was tested using a unified concentration and maximum tolerated threshold concentration. With a PainVision® device, currents were gradually increased in forearm skin to quantify the sensation of pain. Stress levels were measured with electrocardiography and a questionnaire. The median cognitive threshold for taste (salty, sweet, sour, and bitter) was slightly dulled due to chronic mental stress on the day before examination day and was duller than that on the normal day, but the difference was not significant. Pungency and forearm skin pain were significantly dulled on the day before examination day, and pungency correlated significantly with forearm skin pain. Chronic mental stress appeared to dull especially the sensitivity to pungency and skin pain.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"70 6","pages":"445-453"},"PeriodicalIF":0.7,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932085","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}

Vitamin D is routinely recommended for bone health in general population. Our study explores the potential association between low levels (≤20 ng/mL) of vitamin D and mortality in hip fracture patients. Systematic search was done for studies that were published from inception until May 10, 2023, and that report a possible correlation between low vitamin D levels and mortality in patients with hip fractures. A random-effects model was used to assess the effects of normal vitamin D levels on mortality, subgroup analyses were conducted to assess the link between low levels of vitamin D and geographic location of the study and its impact on the recovery process. In 575 identified studies, 18 met the inclusion criteria. A strong connection between low serum levels of vitamin D (<20 ng/mL) and mortality (hazard ratio (HR): 2.29, p<0.001). Further analysis indicated that insufficient (20 to 30 ng/mL) and sufficient (>30 ng/mL) levels of vitamin D levels did not have a significant association with the mortality (HR: 1.10, p=0.12), and (HR: 1.04, p=0.50). As shown by subgroup analysis vitamin D deficiency significantly correlated with mortality in studies conducted in Europe (HR: 2.4). Our results clearly demonstrate that vitamin D deficiency is associated with higher risk of mortality in hip fracture patients. Additional analyses demonstrate that insufficient and sufficient levels of vitamin D were not significantly associated with mortality outcomes in hip fracture patients.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"70 2","pages":"89-97"},"PeriodicalIF":1.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140861491","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}

In this study, we investigated whether the rise of enterohepatic 12-hydroxylated BAs associates with glucose tolerance and/or insulin secretion using rats fed a diet supplemented with cholic acid (CA) at a level of 0.5 g/kg diet. Almost no increase was observed in plasma insulin in response to the intraperitoneal glucose administration in the CA-fed rats despite the significant increase of plasma insulin in control with the same treatment. In contrast, the changes in insulin secretion were observed in both groups and no difference was detected between the groups in the oral glucose tolerance test. Increases were observed in pancreatic expressions of Ins1 and Ins2 although the insulin protein content decreased in the pancreas without any sign in ectopic fat accumulation and histological damage in the CA-fed rats. Our results suggest that enterohepatic 12-hydroxylated BAs modulate insulin secretion in response to intraperitoneal glucose administration. The decrease in insulin store might be responsible for the reduction in the insulin secretion in the CA-fed rats.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"70 1","pages":"76-81"},"PeriodicalIF":1.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139990357","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}

Although it has been considered that increasing energy expenditure increases NAD consumption, little study has directly demonstrated the effect of exercise on niacin nutritional status. We have recently established the niacin insufficient model mice using kynurenine 3-monooxygenase knock out (KMO-/-) mice with niacin-limited diet, which lack the de novo NAD synthesis pathway from tryptophan. To evaluate the effects of chronic endurance exercise on niacin nutritional status, 4 wk old KMO-/- mice were fed 4 or 30 mg/kg nicotinic acid containing diets, and forced to swim in a running water pool every other day for 35 d. The swim-exercised mice fed 4 mg/kg nicotinic acid diet showed lower body weight gain and niacin nutritional markers such as liver and blood NAD, and urine nicotinamide metabolites than the sedentary mice. These animals did not show any difference in the NAD synthesis, NAD salvage and nicotinamide catabolic pathways. Chronic endurance exercise failed to affect any indices in the mice fed the 30 mg/kg nicotinic acid diet. When the diet was exchanged the 4 mg/kg for 30 mg/kg nicotinic acid diet to the mice showed chronic endurance exercise-induced growth retardation, their body weight rapidly increased. These results show that chronic endurance exercise impairs niacin nutritional status in the niacin insufficient mice, and enough niacin intake can prevent this impairment. Our findings also suggest that chronic endurance exercise increases niacin requirement by increase of NAD consumption.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"70 3","pages":"185-192"},"PeriodicalIF":0.7,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141468767","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}

The mechanism mediating glucose suppression in animals is controlled by several actions including the inhibition of sucrase. To investigate the dose-response effects of D-allulose with a sucrose beverage on glucose tolerance and insulin levels using Thai volunteers. This was a prospective, randomized, double-blinded, crossover study. Subjects had five oral sucrose tolerance tests (OSTT) with escalating doses of D-allulose (0, 2.5, 5, 7.5 or 10 g) with a 50 g sucrose beverage in a random order once a week for five consecutive weeks. The five drinks were consumed in a random order; the order being blinded for both subjects and investigators. Blood samples were drawn immediately before consumption and at 30, 60, 90 and 120 min after consumption of the study product for measurement of plasma glucose and insulin levels. Thirty healthy subjects (11 men and 19 women) completed the study. The peak postprandial glucose (PePPG) and insulin levels (PePPI) were lower when D-allulose was added in a dose-dependent manner. The lowest plasma glucose and insulin levels occurred at 120 min after OSTT in all five products and they were raised when D-allulose was added in a dose-dependent manner. D-Allulose has a suppression response on glucose and insulin shown by the decrease in postprandial plasma glucose and insulin levels following the addition of D-allulose to sucrose in a dose-dependent manner. The more D-allulose added, the less marked the glucose and insulin response occurred.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"70 3","pages":"203-209"},"PeriodicalIF":0.7,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141468772","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}

The study was designed as a randomized, double-blind, and placebo-controlled trial. Twenty healthy young adults received either an MFGM powder containing 1.6 g of fat and 160 mg of sphingomyelin or an isocaloric placebo powder daily throughout 4 wk of power or agility training. Physical performance tests and body composition measurements were conducted before and after the 4-wk intervention. Ingestion of MFGM did not affect isometric or isokinetic muscle strength, but it was associated with a greater increase in vertical jump peak power compared with placebo. There were no significant changes in body weight or lean body mass during the intervention period in either group, and no significant differences between groups. We conclude that daily MFGM supplementation combined with exercise training has the potential to improve physical performance in young adults; however, further studies with larger sample sizes should be conducted to obtain more evidence supporting achievement of improved physical performance through MFGM supplementation.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"70 3","pages":"273-279"},"PeriodicalIF":0.7,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141468773","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}
