Abstract in brief

Repeated heating of vegetable oils during cooking produces harmful compounds, such as polycyclic aromatic hydrocarbons (PAHs), which can be carcinogenic and pose health risks through ingestion and inhalation of fumes.
The review highlights that consumption of repeatedly heated cooking oils (RCO) and exposure to their fumes are linked to increased genetic mutations, cellular damage, and a higher incidence of cancers, including lung, colorectal, breast, and prostate cancers.
Studies show that these effects are dose-dependent and that the production of toxic PAHs from RCO contributes significantly to indoor pollution and cancer risk.

Reheating oil creates harmful compounds that can increase your risk of heart disease, high cholesterol, and even cancer. Say NO to ‘gutter oil’ and YES to fresh, heart-friendly cooking! Tag someone still using ‘ancestral’ oil!

If you don't think that's enough risk increase for the population, add foods cooked with repeatedly heated veggie oil, as it’ll increase the cancer risk as well. It feels so nice to know that my govt & MDs take so good care of my health!
