The Role of Dietary Advanced Glycation End Products in Metabolic Dysfunction

Abstract

Advanced glycation end products (AGEs) are a heterogeneous group of molecules produced, non‐enzymatically, from the interaction between reducing sugars and the free amino groups of proteins, nucleic acids, and lipids. AGEs are formed as a normal consequence of metabolism but can also be absorbed from the diet. They have been widely implicated in the complications of diabetes affecting cardiovascular health, the nervous system, eyes, and kidneys. Increased levels of AGEs are also detrimental to metabolic health and may contribute to the metabolic abnormalities induced by the Western diet, which is high in processed foods and represents a significant source of AGEs. While increased AGE levels are a consequence of diabetic hyperglycaemia, AGEs themselves activate signaling pathways, which compromise insulin signaling and pancreatic β‐cell function, thus, contributing to the development of type 2 diabetes mellitus (T2DM). Furthermore, AGEs may also contribute to the obesogenic effects of the Western diet by promoting hypothalamic inflammation and disrupting the central control of energy balance. Here, the role of dietary AGEs in metabolic dysfunction is reviewed with a focus on the mechanisms underpinning their detrimental role in insulin resistance, pancreatic β‐cell dysfunction, hypothalamic control of energy balance, and the pathogenesis of T2DM and obesity.

TL;DR

This review synthesizes mechanisms by which dietary advanced glycation end products (AGEs) contribute to metabolic dysfunction, including insulin resistance, pancreatic β-cell dysfunction, hypothalamic inflammation, obesity, and type 2 diabetes mellitus. It covers AGE formation, absorption, receptor signaling, detoxification, and evidence from cell, animal, and human studies while noting measurement and dietary AGE controversies.

Key findings

  • Dietary AGEs are formed via the Maillard reaction during cooking and processing; around 10–30% are absorbed depending on chemical characteristics, with free low-molecular-weight AGEs absorbed more efficiently than protein-bound AGEs. Foods such as peanuts, biscuits, cereals, toast, and heat-processed meats have the highest measured CML, CEL, and MG-H1 levels (2–5 mg, 2–7 mg, and 15–60 mg per 100 g, respectively), whereas coffee, fruits, vegetables, butter, olive oil, and red wine contain negligible amounts.
  • AGEs activate RAGE and downstream pathways including JNK, IKK/NF-κB, and NADPH oxidase/ROS, promoting inflammation and oxidative stress that impair insulin signaling, downregulate GLUT4, and contribute to β-cell cytotoxicity, apoptosis, and impaired glucose-induced insulin secretion.
  • In animal models, a high-AGE diet containing synthetic MG-BSA at 1 mg per g of diet decreased insulin receptor and IRS phosphorylation and defective AKT activation in skeletal muscle, adipose tissue, and liver. In humans, an AGE-restricted diet improved insulin sensitivity in T2DM and normalized AGER1 and sirtuin1 while decreasing NF-κB acetylation, circulating TNFα, serum AGEs, and leptin; hyperinsulinemic-euglycemic clamp studies showed a low AGE diet improved insulin sensitivity versus a high AGE diet decreasing it.
  • AGEs may promote obesity via hypothalamic inflammation and disrupted central energy balance; a high-fat/high-carbohydrate diet increased CML immunoreactivity in POMC and NPY neurons, and RAGE/ALCAM knockdown improved metabolic phenotype and decreased microglial reactivity. A 5-year follow-up study associated AGEs with increased body weight after adjusting for total energy intake and other confounders.

Methods

  • Narrative review; no primary experimental data are reported. The paper synthesizes published literature on AGE formation, dietary sources and absorption, receptors, detoxification, and metabolic effects.
  • Evidence discussed includes cell culture studies, animal models, human feeding trials, hyperinsulinemic-euglycemic clamps, and cohort follow-up data.
  • Main analysis is a qualitative synthesis of mechanisms and cited findings; no systematic search strategy, meta-analysis, or quantitative pooling is described.

Limitations

  • The paper states there is debate about the relative importance of dietary AGEs because of limited digestion and absorption, particularly of high-molecular-weight AGEs, while low-molecular dietary AGEs appear to be efficiently disposed of by the kidneys.
  • The paper notes intrinsic problems in comparing AGE concentrations across studies due to different measurement techniques and food matrix effects; immunoassays do not give absolute values, whereas mass spectrometry gives absolute concentrations for AGEs such as CML.
  • The paper reports conflicting human feeding studies: some show AGE restriction reduces inflammation and improves vascular function, but two feeding studies showed no effect of dietary AGEs on inflammatory and cardiovascular profiles. Evident from the text: as a narrative review, it lacks systematic search, risk-of-bias assessment, and quantitative synthesis.

    The association between AGEs and increased body weight after adjusting for total energy intake and other confounders is not due to residual confounding.

    “Importantly, the ability of AGEs to increase body weight was retained after adjusting for total energy intake and other cofounders, suggesting AGEs directly affect energy balance.”
  • The paper relies on this without support.

    Mechanisms observed in cell culture and animal models of AGE exposure translate to human metabolic dysfunction.

    “Studies using primary 𝛽-cells and cell lines demonstrate that inhibition of RAGE or antioxidant treatment prevents AGE-induced cell toxicity.[135]”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
