The objective of this research was to examine the potential advantageous impacts of polyphenols extracted from <em>Prunus salicina</em> L. fruit (PSFP) on hyperlipidemia, hepatic steatosis, and hyperglycemia induced by a high-fat diet (HFD), as well as to elucidate the underlying mechanisms involved. Male C57BL/6J mice, free from specific pathogens, were assigned randomly into three groups. These groups were then subjected to a 14-week dietary intervention, including a low-fat diet, an HFD, or an HFD plus with PSFP via intragastric administration. The obesity-related biochemical indexes were evaluated. To assess alterations in gut microbiota resulting from PSFP treatment, 16S rRNA sequencing was performed. UPLC-ESI-MS/MS assay identified 162 distinct polyphenolic compounds in PSFP. The administration of PSFP significantly reduced both body weight gain and hyperlipidemia induced by HFD. In addition, PSFP ameliorated hepatic steatosis induced by HFD and enhanced liver function in mice. PSFP treatment also ameliorated HFD-induced insulin resistance and hyperglycemia, evidenced by the observed decrease in fasting serum concentrations of glucose and insulin, improved insulin sensitivity, and restored glucose tolerance. Moreover, PSFP modulated the composition and abundance of specific microbial genus, including <em>Lachnospiraceae NK4A136 group, Akkermansia, Parabacteroides, Enterococcus, Adlercreutzia</em>, and <em>Roseburia</em>. Correlation analysis indicated significant associations between gut microbiota and physiological indices associated with obesity. These findings suggested that PSFP supplementation ameliorated HFD-induced hyperlipidemia, hepatic steatosis, and hyperglycemia, potentially through modulating the gut microbiota composition and abundance of specific taxa.</div></div>","PeriodicalId":19245,"journal":{"name":"Nutrition Research","volume":"132 ","pages":"Pages 152-163"},"PeriodicalIF":3.4,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142704376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whole milk (including flavored whole milk) intake was assessed using 24-hour dietary recall data of the National Health and Nutrition Examination Survey 2001-2018 for adults age 20+ years (<em>N</em> = 43,038). Weight and related parameters were measured, and history of self-reported weights and total milk intake were obtained from questionnaire data. The association of whole milk intake with weight was assessed via regression after adjusting for demographic and lifestyle-related covariates.

RAW 264.7 macrophages were pretreated with either TEMPOL, a superoxide scavenger, N-acetyl cysteine, a hydroxyl radical and hydrogen peroxide scavenger, or polyphenol extracts from blackberry, blueberry, raspberry, strawberry, kale, and baru nut. After 1 hour of pretreatment, cells were treated with lipopolysaccharides (100 ng/mL) for an additional 6 hour. Antioxidants and polyphenol extracts elicited antioxidant effects in vitro; however, polyphenols regulated redox proteins in a distinct, protective manner, whereas antioxidants, TEMPOL, and N-acetyl cysteine, did not. Additionally, distinct effects were observed in downstream Toll-like receptor 4 signaling and transcriptional activity of inflammatory proteins. We conclude that polyphenols have unique molecular effects that are independent of just their free radical scavenging capacity.

Inter-individual genetic variation may explain some of the observed differences in plasma carotenoid concentrations between individuals. Identifying genetic variants associated with circulating carotenoids in young adults may help identify individuals at increased risk for developing conditions associated with low carotenoids later in life. We hypothesize that common genetic variants are associated with circulating carotenoid concentrations in a population of young adults. A genome-wide association study (GWAS) on plasma carotenoids (α-carotene, β-carotene, β-cryptoxanthin, lutein, and zeaxanthin) was conducted in Caucasians (n = 393) from the Toronto Nutrigenomics and Health Study. Replication cohorts included individuals of Caucasian (n = 193), East Asian (n = 436) and South Asian (n = 135) ethnicity. Linear regression adjusted for age, sex, BMI, total serum cholesterol, dietary carotenoid intake and population structure were used to identify associations between genetic variants and plasma carotenoids. Associations that met the threshold for genome-wide significance (<em>p</em> < 5 × 10<sup>-8</sup>) in unadjusted and partially adjusted models were not observed in the replication cohorts. No variants achieved genome-wide significance in fully adjusted models. Previously identified associations between variation in the <em>PKD1L2/BCO1</em> region and β-carotene, lutein and zeaxanthin were replicated in the GWAS cohort (<em>p</em> < .05). Established variation in the <em>PKD1L2/BCO1</em> region is associated with plasma carotenoids. These variants may help to identify individuals who require greater amounts of these antioxidants and to provide precision nutrition recommendations for optimal intake of various carotenoids.</div></div>","PeriodicalId":19245,"journal":{"name":"Nutrition Research","volume":"132 ","pages":"Pages 164-179"},"PeriodicalIF":3.4,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142721047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
