Pro-inflammatory dietary pattern and the risk of female gout: sex-specific findings from three prospective cohort studies.

Objective: We aimed to determine whether a pro-inflammatory dietary pattern (mechanism-based diet) is associated with incident female gout among two large cohorts of US women.

Methods: We prospectively followed 79,104 women from Nurses' Health Study (NHS; 1984-2016) and 93,454 women from NHSII (1991-2017); 45,445 men from Health Professionals Follow-up Study (1986-2016) served as a comparison cohort. Validated food frequency questionnaires were used to calculate Empirical Dietary Inflammatory Pattern (EDIP; food-based index predictive of circulating inflammatory biomarkers) scores every 4-years.

Pro-inflammatory and hyperinsulinaemic dietary patterns are associated with specific gut microbiome profiles: a TwinsUK cohort study.

Metabolic dietary patterns, including the Empirical Dietary Index for Hyperinsulinaemia (EDIH) and Empirical Dietary Inflammatory Pattern (EDIP), are known to impact multiple chronic diseases, but the role of the colonic microbiome in mediating such relationships is poorly understood. Among 1,610 adults with faecal 16S rRNA data in the TwinsUK cohort, we identified the microbiome profiles for EDIH and EDIP (from food frequency questionnaires) cross-sectionally using elastic net regression. We assessed the association of the dietary pattern-related microbiome profile scores with circulating biomarkers in multivariable-adjusted linear regression.

Proinflammatory Dietary Pattern and Risk of Total and Subtypes of Breast Cancer Among U.S. Women.

Background: Dietary patterns promoting chronic inflammation, including the empirical dietary inflammatory pattern (EDIP), have been associated with certain cancers. Investigating whether this dietary pattern is associated with breast cancer-where the role of inflammation is less well-defined-could provide valuable insights and potentially improve strategies for preventing this cancer.

Methods: We prospectively followed 76,386 women from Nurses' Health Study (NHS, 1984-2018) and 92,886 women from Nurses' Health Study II (NHSII, 1991-2019).

Novel metabolomic predictors of incident colorectal cancer in men and women.

Background: Metabolomic profiles may influence colorectal cancer (CRC) development. Few studies have performed pre-diagnostic metabolome-wide analyses with CRC risk.

Methods: We conducted a nested case-control study among women (Nurses' Health Study (NHS)) and men (Health Professionals Follow-up Study (HPFS)) who provided blood between 1989 and 1995.

Dietary and lifestyle insulinemic potentials, plasma metabolome, and risk of diverticulitis: a prospective cohort study.

Background: Diet and lifestyle factors have been linked to developing diverticulitis. However, it remains largely unknown whether the associations are mediated by metabolic disturbance, such as hyperinsulinemia and corresponding metabolomic perturbations.

Objectives: We investigated associations of the insulinemic potential of diet, lifestyle (diet, physical activity, body weight), and metabolomic patterns with the risk of incident diverticulitis.

Diabetes risk reduction diet and risk of liver cancer and chronic liver disease mortality: A prospective cohort study.

Background: We aimed to prospectively evaluate the association between a diabetes risk reduction diet (DRRD) score and the risk of liver cancer development and chronic liver disease-specific mortality.

Methods: We included 98,786 postmenopausal women from the Women's Health Initiative-Observational Study and the usual diet arm of the Diet Modification trial. The DRRD score was derived from eight factors: high intakes of dietary fiber, coffee, nuts, polyunsaturated fatty acids, low intakes of red and processed meat, foods with high glycemic index, sugar-sweetened beverages (SSBs), and trans fat based on a validated Food-Frequency Questionnaire administered at baseline (1993-1998).

Metabolite Predictors of Breast and Colorectal Cancer Risk in the Women's Health Initiative.

Metabolomics has been used extensively to capture the exposome. We investigated whether prospectively measured metabolites provided predictive power beyond well-established risk factors among 758 women with adjudicated cancers [ = 577 breast (BC) and = 181 colorectal (CRC)] and = 758 controls with available specimens (collected mean 7.2 years prior to diagnosis) in the Women's Health Initiative Bone Mineral Density subcohort.

Developing and evaluating the construct validity of a dietary pattern predictive of plasma TMAO and choline.

Background And Aims: The metabolism of choline (highly present in animal products) can produce trimethylamine N-oxide (TMAO), a metabolite with atherosclerotic effects; however, dietary fiber may suppress this metabolic pathway. This study aimed to develop a dietary pattern predictive of plasma TMAO and choline concentrations using reduced rank regression (RRR) and to evaluate its construct validity.

Methods And Results: Diet and plasma concentrations of choline (μmol/L) and TMAO (μmol/L) were assessed in 1724 post-menopausal women who participated in an ancillary study within the Women's Health Initiative Observational Study (1993-1998).

An Improved Assessment Method to Estimate (Poly)phenol Intake in Adults with Chronic Pancreatitis.

Background: Insights into (poly)phenol exposure represent a modifiable factor that may modulate inflammation in chronic pancreatitis (CP), yet intake is poorly characterized and methods for assessment are underdeveloped.

Aims: The aims are to develop and test a method for estimating (poly)phenol intake from a 90-day food frequency questionnaire (FFQ) using the Phenol-Explorer database and determine associations with dietary patterns in CP patients versus controls via analysis of previously collected cross-sectional data.

Methods: Fifty-two CP patients and 48 controls were recruited from an ambulatory clinic at a large, academic institution.

High-quality fruit and vegetable characterized by cardiometabolic biomarkers and its relation to major chronic disease risk: results from 3 prospective United States cohort studies.

Background: The current guidelines recommend a specified total serving of fruits and vegetables (FV). However, how differences in their nutritional quality of specific FV influence overall health remains unclear.

Objectives: To identify high-quality FV using 14 cardiometabolic biomarkers, and assess their consumption, alongside overall FV intake, with chronic disease risk.

Identifying modifiable risk factors to prevent aggressive colorectal cancer.

It remains unclear if pre-diagnostic factors influence the developmental pathways of colorectal cancer (CRC) that could enhance tumor aggressiveness. This study used prospective data from 205,489 cancer-free US health professionals to investigate the associations of 31 known or putative risk factors with the risk of aggressive CRC. Tumor aggressiveness was characterized by three endpoints: aggressive CRC (cancer that causes death within 5 years of diagnosis), fatal CRC, and tumor stage at diagnosis.

Dietary inflammatory pattern and risk of hip fracture in the Nurses' Health Study.

Unlabelled: Our immune system activity is impacted by what we eat and can influence fracture risk under certain conditions. In this article, we show that postmenopausal women with a pro-inflammatory dietary pattern have an increased risk of hip fracture.

Purpose: The immune system influences bone homeostasis and can increase the risk of fracture under certain pro-inflammatory conditions.

Metabolomic signatures of inflammation and metabolic dysregulation in relation to colorectal cancer risk.

Background: Inflammation and metabolic dysregulation are associated with increased risk of colorectal cancer (CRC); the underlying mechanisms are not fully understood. We characterized metabolomic signatures of inflammation and metabolic dysregulation and evaluated the association of the signatures and individual metabolites with CRC risk.

Methods: Among 684 incident CRC cases and 684 age-matched controls in the Nurses' Health Study (n = 818 women) and Health Professionals Follow-up Study (n = 550 men), we applied reduced rank and elastic net regression to 277 metabolites for markers of inflammation (C-reactive protein, interleukin 6, tumor necrosis factor receptor superfamily member 1B, and growth differentiation factor 15) or metabolic dysregulation (body mass index, waist circumference, C-peptide, and adiponectin) to derive metabolomic signatures.

Healthy dietary patterns and risk of prostate cancer in men at high genetic risk.

Prostate cancer has high heritability. Healthy lifestyle has been associated with lower lethal prostate cancer risk among men at increased genetic susceptibility, but the role of healthy dietary patterns remains unknown. We prospectively followed 10,269 genotyped men in the Health Professionals Follow-up Study (1993-2019).

The metabolic potential of inflammatory and insulinaemic dietary patterns and risk of type 2 diabetes.

Aims/hypothesis: Diets with higher inflammatory and insulinaemic potential have been associated with an increased risk of type 2 diabetes. However, it remains unknown whether plasma metabolomic profiles related to proinflammatory/hyperinsulinaemic diets and to inflammatory/insulin biomarkers are associated with type 2 diabetes risk.

Methods: We analysed 6840 participants from the Nurses' Health Study and Health Professionals Follow-up Study to identify the plasma metabolome related to empirical dietary inflammatory pattern (EDIP), empirical dietary index for hyperinsulinemia (EDIH), four circulating inflammatory biomarkers and C-peptide.

Association of Later-Life Weight Changes With Survival to Ages 90, 95, and 100: The Women's Health Initiative.

Background: Associations of weight changes and intentionality of weight loss with longevity are not well described.

Methods: Using longitudinal data from the Women's Health Initiative (N = 54 437; 61-81 years), we examined associations of weight changes and intentionality of weight loss with survival to ages 90, 95, and 100. Weight was measured at baseline, year 3, and year 10, and participants were classified as having weight loss (≥5% decrease from baseline), weight gain (≥5% increase from baseline), or stable weight (<5% change from baseline).

Association of dietary insulinemic and inflammatory potential with risk of liver cancer and chronic liver disease mortality in postmenopausal women: a prospective cohort study.

Background: Low diet quality, diabetes, and chronic inflammation are risk factors of liver cancer and chronic liver disease (CLD), but the extent to which insulinemic and inflammatory diets are independently associated with risk of liver cancer and CLD mortality is unknown.

Methods: We conducted a prospective cohort analysis among 78,356 postmenopausal women in the Women's Health Initiative Observational Study. Two validated dietary indices, the empirical dietary index for hyperinsulinemia (EDIH) and the empirical dietary inflammation pattern (EDIP), were estimated from a food-frequency questionnaire.
