Why reused frying oil can be dangerous for your heart and health

Reusing fried oil is common but harmful. FSSAI advises avoiding reuse or limiting it to a maximum of three times, never mixing old and fresh oil. Reheated oil forms toxic compounds that raise risks of heart disease, cancer, and inflammation. Street vendors must follow strict guidelines. Properly cool, strain, store, and recycle used oil—never pour it down the drain.
