Objective: Dietary advanced glycation end products (AGEs) intake may be associated with coronary heart disease (CHD) risk. We aimed to investigate the association between dietary AGEs intake and CHD risk and to further investigate whether this association could be influenced by genetic risk.

Methods: Data from UK Biobank were used. Dietary AGEs intake, including Nε-(carboxymethyl) lysine (CML), Nε-(1-Carboxyethyl)-L-lysine (CEL), and Nd-(5-hydro-5-methyl-4-imidazolon-2-yl)-ornithine (MG-H1) were calculated by coupling the consumption of food items from 24-hour dietary recall with the dietary AGEs database. Baseline dietary information was first collected through Oxford WebQ 24 h food recall between April 2009 and September 2010. From February 2011 to June 2012, the Oxford WebQ survey was conducted online in four rounds. The association between dietary AGEs and CHD risk was estimated using multivariable-adjusted Cox proportional risk models. The association between dietary AGEs intake and genetic risk with CHD risk was further explored via the multiplicative interaction analyses.

Results: During a median follow-up of 12.2 years, 4,348 participants developed CHD. In the fully adjusted model, a higher intake of dietary AGEs, CML and MG-H1 (highest tertile vs. lowest tertile) was associated with a higher risk of CHD [HR, (95% CI):1.12 (1.03,1.23), 1.15 (1.05,1.26) and 1.10 (1.00,1.20), respectively (all P trend < 0.05)]. Among participants with intermediate to high genetic risk, HRs (95% CI) were 1.63 (1.39, 1.91) and 2.45 (2.10, 2.85) for AGEs, 1.67 (1.42, 1.97) and 2.60 (2.23, 3.02) for CML, 1.48 (1.26 1.74) and 2.34 (2.01, 2.72) for CEL, and 1.64 (1.40, 1.92) and 2.31 (1.99, 2.69) for MG-H1, respectively.

Conclusions: Higher intakes of dietary AGEs, CML and MG-H1 were associated with an increased risk of coronary heart disease, and there was an interaction between dietary AGEs intake and genetic predisposition on the risk of CHD.

Both dietary and endogenous reactive carbonyl species, such as methylglyoxal (MGO) and glyoxal (GO), react with proteins to generate advanced glycation end products (AGEs), which contribute to metabolic diseases. However, accurately determining individual AGEs in biological samples remains challenging due to the lack of standardized methods. In this study, we optimized and detailed procedures for AGE digestion using enzyme cocktails and separation and detection via high-resolution LC-MS/MS.

Background: As the global population ages, extending not only the life expectancy (LE) but also the healthy life expectancy (HALE) has become a critical public health objective. Dietary choices, especially the intake of various fatty acids, may play a role in achieving good health.

Objective: The aim of this study was to describe the intake of fatty acid (FA) fractions across different countries and explore its associations with HALE and LE from 2010 to 2019 according to publicly available international data.

Malnutrition, encompassing both undernutrition and overnutrition, is prevalent among patients with chronic kidney disease (CKD). It is influenced by a myriad of factors, including dietary restrictions, metabolic irregularities, inflammation, and comorbidities. It leads to increased morbidity, mortality, and diminished quality of life.
