Many households regularly reuse cooking oil to save money and reduce waste. While this practice seems economical and environmentally friendly, recent research has raised important questions about its potential health implications, particularly regarding cancer risk. Understanding the science behind oil degradation and its effects on human health can help you make informed decisions about your cooking practices.
When cooking oils are heated repeatedly, they undergo complex chemical changes that can produce harmful compounds. These transformations occur at the molecular level, affecting both the nutritional value and safety of the oil. The repeated heating process breaks down the oil's natural structure, creating substances that may pose health risks when consumed regularly.
