Project description:In this study we conducted a randomized, controlled, cross-over single-meal study
comparing a meal with highly fermented yogurt and cheese, and a meal with beef
and pork meatballs. Postprandial urine samples from 17 subjects were collected
sequentially after each meal up to 24 hr and analyzed by untargeted metabolomics
through an UHPLC-qTOF.

Project description:This study aimed to investigate the systemic immunological effects of kimchi consumption in humans. We conducted a 12-week randomized, double-blind, placebo-controlled clinical trial involving thirteen overweight but otherwise healthy adults who consumed either placebo, spontaneously fermented kimchi (S-K), or starter kimchi fermented with Leuconostoc mesenteroides KCKM0828 (LMS-K). Peripheral blood mononuclear cells (PBMCs) were collected before and after the intervention and subjected to single-cell RNA sequencing (scRNA-seq) to profile immune responses at single-cell resolution.

Project description:Randomized controlled trials suggest that protein restriction may retard the progression of CKD toward ESRD. However, the effects of dietary protein intake level and the food sources of dietary protein on the risk of ESRD in the general population remain unclear. We investigated these effects in the Singapore Chinese Health Study, a prospective population-based cohort that recruited 63,257 Chinese adults aged 45-74 years from 1993 to 1998. We collected habitual diet information via a validated semiquantitative food frequency questionnaire and identified ESRD via record linkage with a nationwide registry. In all, 951 cases of ESRD occurred over a mean follow-up of 15.5 years. Regarding total protein intake, compared with the lowest quartile, the three higher quartiles combined had a hazard ratio for ESRD of 1.24 (95% confidence interval [95% CI], 1.05 to 1.46), but the dose-dependent association across the quartiles was not statistically significant (Ptrend=0.16). Red meat intake strongly associated with ESRD risk in a dose-dependent manner (hazard ratio for highest quartile versus lowest quartile,1.40 [95% CI, 1.15 to 1.71; Ptrend<0.001]). Intake of poultry, fish, eggs, or dairy products did not associate with risk of ESRD. In substitution analysis, replacing one serving of red meat with other food sources of protein associated with a maximum relative risk reduction of 62.4% (95% CI, 33.1 to 78.9; P<0.01). Our study shows that red meat intake may increase the risk of ESRD in the general population and substituting alternative sources of protein may reduce the incidence of ESRD.

Project description:Associations of low-to-moderate consumption of red and processed meat with mortality would add to the evidence of possible adverse effects of these common foods. This study aims to investigate the association of red and processed meat intake with mortality. The Adventist Health Study-2 (AHS-2) is a prospective cohort study of ~96,000 Seventh-day Adventist men and women recruited in the US and Canada between 2002 and 2007. The final analytic sample after exclusions was 72,149. Cox proportional hazards regression was used and hazard ratios (HR) and confidence intervals (CI) were obtained. Diet was assessed by a validated quantitative food frequency questionnaire (FFQ), calibrated using six 24-h dietary recalls. Mortality outcome data were obtained from the National Death Index. During a mean follow-up of 11.8 years, there were 7961 total deaths, of which 2598 were Cardiovascular diseases (CVD) deaths and 1873 were cancer deaths. Unprocessed red meat was associated with risk of all-cause mortality (HR: 1.18; 95% CI: 1.07⁻1.31) and CVD mortality (HR: 1.26; 95% CI: 1.05⁻1.50). Processed meat alone was not significantly associated with risk of mortality. The combined intake of red and processed meat was associated with all-cause mortality (HR: 1.23; 95% CI: 1.11⁻1.36) and CVD mortality (HR: 1.34; 95% CI: 1.12⁻1.60). These findings suggest moderately higher risks of all-cause and CVD mortality associated with red and processed meat in a low meat intake population.

Project description:Fermented dairy milks have been associated with many health benefits including the regulation of metabolic dysfunction. Different circulating clinical biomarkers have been used to explore the effect of fermented milks on metabolic health but the development of whole blood transcriptomics has recently been proposed as a source of novel biomarkers for this health outcome. In a randomised, cross-over study, we evaluate the changes in the whole blood transcriptome after the intake of a probiotic yoghurt compared to a milk acidified with gluconic acid in seven healthy young men. The effects of the dairy foods on whole blood gene expression were assessed at three time points during a 6 h postprandial test (800g single dose) and in the fasting state after a daily intake of the products over two-weeks (400g/d). RNA was extracted from Paxgene ® whole blood samples and sequenced on the Illumina HiSeq platform.

Project description:PURPOSE: Red and processed meat intake is convincingly associated with colorectal cancer (CRC) incidence, but its impact on prognosis after CRC diagnosis is unknown. We examined associations of red and processed meat consumption, self-reported before and after cancer diagnosis, with all-cause and cause-specific mortality among men and women with invasive, nonmetastatic CRC. PATIENTS AND METHODS: Participants in the Cancer Prevention Study II Nutrition Cohort reported information on diet and other factors at baseline in 1992-1993, 1999, and 2003. Participants with a verified CRC diagnosis after baseline and up to June 30, 2009, were observed for mortality through December 31, 2010. RESULTS: Among 2,315 participants diagnosed with CRC, 966 died during follow-up (413 from CRC and 176 from cardiovascular disease [CVD]). In multivariable-adjusted Cox proportional hazards regression models, red and processed meat intake before CRC diagnosis was associated with higher risks of death as a result of all causes (top v bottom quartile, relative risk [RR], 1.29; 95% CI, 1.05 to 1.59; Ptrend = .03) and from CVD (RR, 1.63; 95% CI, 1.00 to 2.67; Ptrend = .08) but not CRC (RR, 1.09; 95% CI, 0.79 to 1.51; Ptrend = 0.54). Although red and processed meat consumption after CRC diagnosis was not associated with mortality, survivors with consistently high (median or higher) intakes before and after diagnosis had a higher risk of CRC-specific mortality (RR, 1.79; 95% CI, 1.11 to 2.89) compared with those with consistently low intakes. CONCLUSION: This study suggests that greater red and processed meat intake before diagnosis is associated with higher risk of death among patients with nonmetastatic CRC.

Project description:To examine the association between red meat subtypes intake and risk of colorectal cancer (CRC) among Jewish and Arabs populations in a unique Mediterranean environment. The Molecular Epidemiology of Colorectal Cancer study (n=10 026) is a prospective population-based case-control study in northern Israel. Participants were interviewed in-person about their dietary intake and lifestyle using a questionnaire that included a food-frequency questionnaire. Red meat consumption in Israel was found to be especially low in the Jewish population (1.29±1.45 servings/week), but higher in Arabs (3.0±1.98 servings/week) (P<0.001). Beef was the most commonly consumed red meat by Jews (1.15/1.29 servings/week, 89%) and proportionally less so by Arabs (2.00/3.00, 67%). Processed meat consumption (mostly pork free) was lower among Arabs (0.9±1.56 servings/week) compared with Jews (1.97±2.97 servings/week) (P<0.001). The adjusted odds of CRC per one serving/week of red meat were 1.05 (95% confidence interval: 1.01-1.08) in Jews and 0.94 (0.88-1.01) in Arabs. Compared with no consumption, beef consumption was associated with odds ratio (OR)=0.96 (0.86-1.07) in Jews and 0.94 (0.61-1.45) in Arabs, lamb consumption with OR=1.28 (1.10-1.5) and 1.01 (0.75-1.37), pork consumption with OR=1.44 (1.24-1.67) and 1.07 (0.73-1.56), and processed meat consumption with OR=1.22 (1.10-1.35) and 1.04 (0.82-1.33) in Jews and Arabs, respectively. Overall red meat consumption was associated weakly with CRC risk, significant only for lamb and pork, but not for beef, irrespective of tumor location. Processed meat was associated with mild CRC risk.

Project description:Heterogeneity in meat food groups hinders interpretation of research regarding meat intake and chronic disease risk. Our objective was to investigate how heterogeneity in red meat (RM) and poultry food groups influences US population intake estimates. Based on a prior systematic review, we created an ontology of methods used to estimate RM [1= unprocessed RM; 2 (reference)= unprocessed RM + processed RM; 3= unprocessed RM + processed RM + processed poultry; and 4=unprocessed RM + processed RM + processed poultry + chicken patties/nuggets/tenders (PNT)] and three for poultry [A=unprocessed poultry; B= unprocessed poultry + PNT; C (reference)= unprocessed poultry + processed poultry + PNT). We applied methods to 2015-18 National Health and Nutrition Examination Survey data to estimate RM and poultry intake prevalence and amount. We estimated and compared intakes within RM and within poultry methods via the NCI Method for individuals ≥2 years old (n = 15,038), adjusted for age, sex, and race/Hispanic origin. We compared the population percentage that exceeded age- and sex-specific RM and poultry allotments from the Dietary Guidelines for Americans recommended eating patterns. The percent that consumed RM ranged from 47 ± 1.2% to 75 ± 0.8% across methods and mean amount ranged from 10.5 ± 0.28 to 18.2 ± 0.35 lean oz-equivalents/week; 38 ± 1.2% to 71 ± 0.7% and 9.8 ± 0.35 to 13.3 ± 0.35 lean oz-equivalents/week across poultry methods. Estimates for higher, but not lower, intake percentiles differed across RM methods. Compared to the reference, Method 1 was ≥3.0 oz-equivalents/week lower from 20th-70th percentiles, ≥6.0 oz-equivalents/week lower from 75th-90th percentiles, and ≥9.0 oz-equivalents/week lower for the 95th percentile. Method 4, but not Method 3, was ≥3.0 oz-equivalents/week higher than the reference from 50 to 95th percentiles. The population percentage that exceeded allotments was 27 ± 1.8% lower for Method 1, 9 ± 0.8% higher for Method 3, and 14 ± 0.9% higher for Method 4 compared to the reference. Differences were less pronounced for poultry. Our analysis quantifies the magnitude of bias introduced by heterogeneous meat food group methodology. Explicit descriptions of meat food groups are important for development of dietary recommendations to ensure that research studies are compared appropriately.
