The Claim
Lipid oxidation during frying generates reactive carbonyl compounds such as methylglyoxal and glyoxal, which act as direct precursors to advanced glycation end products and contribute to their accumulation in fried foods independently of the Maillard reaction.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When fats are heated during frying, chemical reactions produce reactive compounds like methylglyoxal and glyoxal that directly form advanced glycation end products in fried foods, even without the Maillard reaction.

Lipid oxidation during frying generates reactive carbonyl compounds such as methylglyoxal and glyoxal, which act as direct precursors to advanced glycation end products and contribute to their accumulation in fried foods independently of the Maillard reaction.
When oil is heated during frying, its fats break down and produce harmful chemicals called methylglyoxal and glyoxal. These chemicals stick to proteins in the food and form permanent, harmful clumps known as advanced glycation end products, even without any sugar being involved.
What the research says
1 studyStudy: Acrylamide and Advanced Glycation End Products in Frying Food: Formation, Effects, and Harmfulness
When you fry food, the oil breaks down and makes chemicals that can stick to proteins in the food and create harmful substances, even without sugar being involved. This study says frying creates dangerous compounds, which includes those chemicals.
