Introduction
There is a lack of biomarkers of clinically important diets, such as the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet.
Objectives
Our study explored serum metabolites associated with adherence to the MIND diet.
Methods
In 3,908 Atherosclerosis Risk in Communities (ARIC) study participants, we calculated a m...
Our aim was to conduct an umbrella review of evidence from meta-analyses of observational studies investigating the link between sugar-sweetened beverage consumption and human health outcomes. Using predefined evidence classification criteria, we evaluated evidence from 47 meta-analyses encompassing 22,055,269 individuals. Overall, 79% of these ana...
Background
Consumption of ultra‐processed food, which is manufactured food that is high in additives and sparse in intact foods, is adversely associated with cardiovascular health, primarily in non‐US study populations. We aimed to estimate the association between ultra‐processed food consumption and incident hypertension in middle‐aged adults in t...
Background
Patients with chronic kidney disease (CKD) are encouraged to choose refined grains instead of whole grains as part of the low-phosphorus diet for managing chronic kidney disease-mineral and bone disorders (CKD-MBD). However, there is no direct evidence indicating that limiting whole grains has a beneficial impact on CKD outcomes.
Method...
Purpose of review
Plant-based diets are associated with a lower risk of hypertension, diabetes, cardiovascular disease, and mortality. Using the most recent evidence, we critically appraised the role of plant-based diets in primary and secondary prevention of chronic kidney disease (CKD) with a focus on key nutritional factors (dietary acid load, p...
Aims/hypothesis
Understanding the impact of the overall construct of ultra-processed foods on diabetes risk can inform dietary approaches to diabetes prevention. In this study, we aimed to evaluate the association between ultra-processed food consumption and risk of diabetes in a community-based cohort of middle-aged adults in the USA. We hypothesi...
Background
High dietary calcium and phosphorus may accelerate vascular calcification, but epidemiological data are inconsistent. Most of those studies assessed diet at one point and have not been systematically evaluated.
Objectives
The purpose of this study was to assess the associations of dietary calcium and phosphorus intakes in middle age wit...
Circulating α1-acid glycoprotein (AGP) and C-reactive protein (CRP) are commonly measured to assess inflammation, but these biomarkers fail to reveal the complex molecular biology of inflammation. We mined the maternal plasma proteome to detect proteins that covary with AGP and CRP. In 435 gravida predominantly in <12-week gestation, we correlated...
Key Points
We provide an atlas of cross-sectional and longitudinal serum and urine metabolite associations with eGFR and urine albumin-creatinine ratio in an older community-based cohort.
Metabolic profiling in serum and urine provides distinct and complementary insights into disease.
Background
Metabolites represent a read-out of cellular process...
Rationale & Objective
Tubulointerstitial damage is a feature of early chronic kidney disease (CKD), but current clinical tests capture it poorly. Urine biomarkers of tubulointerstitial health may identify risk of CKD.

Introduction: Understanding the association between low glucose readings (hypoglycemia) detected by CGM and hypoglycemic symptoms experienced by people with diabetes is critically important for diabetes management. However, tools that capture hypoglycemic symptoms in real-time are lacking.
Objective: Implement a real-time hypoglycemia symptom repor...
Background: Metabolomics may identify novel biomarkers for predicting, detecting, and managing diabetes. We evaluated the association of novel metabolites with diabetes, prediabetes, and continuous glycemic outcomes (fasting plasma glucose (FPG); hemoglobin A1c (HbA1c)) using data from the Bogalusa Heart Study (BHS) and Atherosclerosis Risk in Comm...
Introduction: Consuming a plant-based diet is associated with a lower risk of cardiometabolic disorders and lower greenhouse gas emissions. Furthermore, a vegetarian diet is considered a healthy dietary pattern according to the U.S. Dietary Guidelines for Americans and strongly aligns with the 2021 AHA Dietary Guidance. Yet, little is known about c...
Background: For individuals with prediabetes and diabetes, the Centers for Disease Control and Prevention recommends consuming more whole foods rather than highly processed foods as part of the everyday diet. Trends in ultra-processed foods (UPFs) consumption among adults with diabetes and prediabetes in the general population are uncharacterized....

Plant-based dietary patterns emphasize plant foods and minimize animal-derived foods. We investigated the association between plant-based dietary patterns and diabetes in a community-based U.S. sample of Black and White adults.
RESEARCH DESIGN AND METHODS
We included middle-aged adults from the Atherosclerosis Risk in Communities (ARIC)...
Rationale & Objective
While urine excretion of nitrogen estimates the total protein intake, biomarkers of specific dietary protein sources have been sparsely studied. Using untargeted metabolomics, this study aimed to identify serum metabolomic markers of 6 protein-rich foods and to examine whether dietary protein–related metabolites are associated...
Cow’s milk is frequently included in the human diet, but the relationship between milk intake and type 2 diabetes (T2D) remains controversial. Here, using data from the Hispanic Community Health Study/Study of Latinos, we show that in both sexes, higher milk intake is associated with lower risk of T2D in lactase non-persistent (LNP) individuals (de...

Background
Within healthy dietary patterns, manipulation of the proportion of macronutrient can reduce CVD risk. However, the biological pathways underlying healthy diet-disease associations are poorly understood. Using an untargeted, large-scale proteomic profiling, we aimed to (1) identify proteins mediating the association between healthy dietar...
Objective:
N-terminal pro-brain-type natriuretic peptide (NT-proBNP) is a marker of cardiac wall stress and is a predictor of cardiovascular disease. Higher diet quality is associated with lower risk of cardiovascular disease. The association between diet quality and subclinical cardiovascular disease assessed by NT-proBNP is uncharacterized. We i...
BACKGROUND
The DASH (Dietary Approaches to Stop Hypertension) diets reduced blood pressure (BP) in the DASH and DASH-Sodium trials, but the underlying mechanisms are unclear. We identified metabolites associated with systolic BP or diastolic BP (DBP) changes induced by dietary interventions (DASH versus control arms) in 2 randomized controlled feed...

Introduction: N-terminal pro-brain-type natriuretic peptide (NT-proBNP) is widely used as a diagnostic biomarker for heart failure. Higher diet quality is associated with lower risk of cardiovascular disease. However, the association between diet and subclinical cardiovascular disease, as assessed by biomarker concentrations, is less well-studied....

Introduction: There is inconsistent evidence on the efficacy of a low-protein diet for patients with chronic kidney disease (CKD) and there is a lack of objective biomarkers of dietary intake. The purpose of this study was to identify plasma metabolites associated with dietary intake of protein among children with CKD and to assess whether protein-...
Background: High dietary calcium and phosphorus intakes may accelerate vascular calcification. A few studies have explored the association of dietary calcium and phosphorus intakes with vascular calcification but reported inconsistent results. Most studies relied on dietary assessment at one time point and evaluated only coronary artery calcificati...
Introduction: There is a lack of objective biomarkers of dietary intake. Untargeted studies can unbiasedly identify dairy biomarkers and inform the creation of robust dietary assessment tools that integrate questionnaire and biospecimen data.
Methods: Dairy products from interviewer-administered questionnaires were categorized as either low-fat or...
