The intervention period was from January 2018 to May 2018. The means and standard deviations for vitamin D status (25-hydroxyvitamin D3, nmol/L), pre- and post-test, respectively, were 58(21) and 46(15) for the Control group, and 63(18) and 76(21) for the Vitamin D group. Problem-solving and planning abilities were measured by the Tower of London (ToL) task pre- (midwinter) and post- (spring) supplement intervention. The ToL task was performed during exposure to distracting noise. \u0000Results: The results revealed that vitamin D supplementation throughout the winter had a significant effect on number of correct responses on easier (1 and 2 move) ToL problems during stress; the Vitamin D group improved significantly from pre- to post-test, whereas the Control group did not. In addition, the Vitamin D group had significantly more correct responses than the Control group on post-test. The improved performance was not related to a speed-accuracy trade off effect; both groups showed significantly decreased planning times from pre- to post-test. The intervention did not differentially affect task performance on the more difficult (3 to 5 move) ToL problems. For the more demanding problems, IQ seemed to explain most of the variance regarding accuracy. Age explained most of the variance associated with task planning time. \u0000Conclusion: Vitamin D supplementation seemed to improve resilience to stress, but it was limited to performance of easier tasks \u0000 ","PeriodicalId":149344,"journal":{"name":"Food & Nutrition Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121467884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its anti-obesity effects, which are a result of attenuating abnormal lipid and glucose metabolisms, have also been reported. \u0000Aim: The purpose of this study is to investigate the effect of BH on genes and proteins that are involved in the adipocyte differentiation using 3T3-L1 cells. \u0000Methods: The effects of the water extracts of the BH were examined on adipogenesis and lipolysis using a biochemical and molecular analysis of the 3T3-L1 cells. \u0000Results: Cyanidin-3-O-glucoside (C3G) from the BH extract was determined in order to contain 1.67 mg/g by the high-performance liquid chromatography analysis. The lipid accumulation in the adipocytes was reduced, which ranged from 58 to 26% in the BH (500 and 1,000 µg/mL) compared to the control group. The lipolysis that was measured by the glycerol content was not affected by the BH at 1,000 μg/mL. The BH downregulated the expression of the main transcription factors of the adipogenesis pathway, such as peroxisome proliferator-activated receptor γ, 1, 2, adipose differentiation-related protein, CCAAT/enhancer binding protein α, and acetyl CoA carboxylase, while increasing the expression of the Adenosine monophosphate (AMP)-activated protein kinase α. \u0000Conclusion: These findings suggest that the BH is a good source of C3G, and it could be effective in regard to inhibiting the adipogenesis as opposed to the lipolysis, which indicates the potential for natural anti-obesity ingredients.","PeriodicalId":149344,"journal":{"name":"Food & Nutrition Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131668498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the mechanisms by which it affects the control of energy metabolism have not been fully elucidated. \u0000Objective: The present work aimed to clarify the mechanisms by that B. lactis A12 has an effect on the management of energy metabolism. \u0000Design: Three- to five-week-old male C57BL/6J mice were randomly divided into five groups, 15 mice for each group. Low-fat diet (LFD) group and high-fat diet (HFD) group were fed with phosphate-buffered saline (PBS) on a daily basis. Cell-free supernatant (CFS), A12, and B. lactis BB12 (BB12) groups were fed with daily probiotics for 10 weeks (1 × 109 CFU of every strain). \u0000Results: The results showed that A12 effectively alleviated relieved weight gain and dyslipidemia, inhibited liver adipose accumulation, and improved leptin resistance in HFD-fed mice (p < 0.05). The anti-obesity effects of B. lactis A12 were closely related to the assembly of short-chain fatty acids (SCFAs), SCFA-downstream receptors, and glucagon-like peptide-1 (GLP-1) secretion. Additionally, high-throughput sequencing of the 16S rRNA showed that B. lactis A12 supplementation reversed HFD-induced gut microbiota dysbiosis, which was possible related to the augmented abundance of SCFA-producing bacterium and a minimized ratio of Bacteroidetes to Firmicutes in mice. \u0000Conclusions: B. lactis A12 prevents obesity in some pathways, including the downregulation of sterol regulatory element binding protein-1 mRNA levels in the liver, modulation of the structure of gut microbiota in a gut microbiota-dependent manner, and the upregulation of the SCFA-producing bacteria-related G protein-coupled receptor 43 pathway.","PeriodicalId":149344,"journal":{"name":"Food &amp; Nutrition Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129969007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effects of LDP-1 on C. elegans induced by heat and oxidative stress were, respectively, performed in an artificial climate chamber and Juglone solution. Determination of lipofuscin levels in C. elegans was observed by laser confocal scanning microscopy. Determination of reactive oxygen species in C. elegans in vivo was conducted via fluorescence spectrophotometer reader. \u0000Results: The results revealed that LDP-1 could significantly extend the lifespan of C. elegans, and the lifetime of C. elegans treated with 1,000 μg/mL LDP-1 could be prolonged by 32.8% compared with the control. The survival rates of the experimental C. elegans under heat shock and oxidative stress conditions were clearly improved after treated with 1,000 μg/mL LDP-1 (40 and 19.8%, respectively), while under the same circumstances all the C. elegans in the blank group died. Fluorescence microscopy analysis confirmed that LDP-1 could effectively reduce the accumulation of lipofuscin and reactive oxygen free radicals in C. elegans, where the respective maximum reduction reached 22.8 and 42.7% compared with the control. \u0000Conclusion: These results indicate that LDP-1 had favorable antioxidant and anti-aging effects, which could be explored as potential dietary additives to renovate oxidative damage and slow down aging process.","PeriodicalId":149344,"journal":{"name":"Food &amp; Nutrition Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128697249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explored the effects of circadian dysregulation on the rhythms of intestinal BA metabolism. \u0000Method: Period circadian clock 1/period circadian clock 2 (Per1/Per2) double gene knockout (DKO) and wild-type (WT) male C57BL/6 mice were fed with a control or high-fat diet for 16 weeks. We measure plasma parameters of mice. Pathological changes including those in liver and intestine were detected by hematoxylin and eosin (H&E) and oil O staining. Western blot was used to detect the intestinal core rhythm protein clock circadian regulator (CLOCK), nuclear receptor subfamily 1, group D, member 1 (REV-ERBα), Farnesoid X receptor (FXR), Small heterodimer partner (SHP), and Fibroblast growth factor 15 (FGF15) expressions. We analyzed the bile acid and intestinal flora profile in the mice intestine tissues by BA-targeted metabolomics detection and high-throughput sequencing. \u0000Results: Rhythmic chaos affected lipid metabolism and lipid accumulation in mice liver and intestine, and diurnal fluctuations of plasma triglycerides (TGs) were absent in normal-feeding DKO mice. The normal circadian fluctuations of the CLOCK and REV-ERBα observed in wild mice disappeared (normal diet) or were reversed (high-fat diet) in DKO mice. In WT mice intestine, total BA and conjugated BA were affected by circadian rhythm under both normal and high-fat diets, while these circadian fluctuations disappeared in DKO mice. Unconjugated BA seemed to be affected exclusively by diet (significantly increased in the high-fat group) without obvious fluctuations associated with circadian rhythm. Correlation analysis showed that the ratio of conjugated/unconjugated BA was positively correlated with the presence of Bacteroidetes and displayed a circadian rhythm. The expression levels of BA receptor pathway protein FXR, SHP, and FGF15 were affected by the ratio of conjugated/unconjugated BA. \u0000Conclusion: Bacteroidetes-related diurnal changes to intestinal ratios of conjugated/unconjugated BA have the potential to regulate diurnal fluctuations in liver BA synthesis via FXR-FGF15. The inverted intestinal circadian rhythm observed in DKO mice fed with a high-fat diet may be an important reason for their abnormal circadian plasma TG rhythms and their susceptibility to lipid metabolism disorders. \u0000 ","PeriodicalId":149344,"journal":{"name":"Food &amp; Nutrition Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128819278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Data were derived from the 2013 Philippine National Nutrition Survey. A total of 6,565 children aged 6-12 years across all the 17 regions that participated in the survey were analyzed. Two (2) non-consecutive day 24-hour dietary recalls (24hR) were collected to estimate the individual food intake. PC-SIDE version 1.0 software (Software for Intake Distribution Estimation) was used to estimate the usual intake of energy and key nutrients accounting for between - and within-person differences in dietary intake. The 2007 WHO Protein Digestibility Corrected Amino Acid Score (PDCAAS) method was used to measure the protein quality or the utilizable protein intake. Results: School-aged children were found to have lower dietary intake of utilizable protein than total protein. Higher consumption of grains and meat decreased the prevalence of stunting. Furthermore, linear growth of children was found to be associated with the dietary intake of several nutrients including utilizable protein, calcium, vitamin B12, vitamin C and vitamin D. The prevalence of stunting and underweight significantly decreased with a higher consumption of utilizable protein. Milk consumption decreased the prevalence of underweight. The prevalence of underweight also decreases with a higher dietary consumption of calcium, riboflavin and vitamin C. Higher consumption of grains also decreased the prevalence of underweight and wasting. A decreased prevalence of wasting was also found with higher dietary consumption of riboflavin, thiamine and fiber. On the contrary, higher consumption of meat, milk and grains increased the prevalence of obesity. In particular, higher dietary consumption of utilizable protein and vitamin C increased the prevalence of obesity. Conclusions: Even though the dietary total protein intake of school-aged children is considered adequate, the existence of malnutrition among children may be specifically attributed to quality of protein consumed. Therefore, the study suggests that nutrition interventions and policies focusing on child malnutrition should improve not just the quantity, but the quality of protein sources consumed by children to aid in proper growth and development.","PeriodicalId":149344,"journal":{"name":"Food &amp; Nutrition Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117280115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
