What actually happens when cooking oil is reused and why it matters
Repeatedly heating cooking oil triggers a chemical chain reaction, breaking down triglycerides and forming harmful compounds like aldehydes. These byproducts can bind to proteins and DNA, leading to oxidative stress and inflammation. While occasional reuse is acceptable, excessive reheating, especially in commercial settings, poses significant health risks.
