“Greasy food cures a hangover.”
Moderate confidence. Authoritative guidance and systematic reviews find no proven hangover cure beyond time, and there is no credible evidence that greasy food speeds alcohol clearance or reverses the underlying recovery process. Direct trials of greasy meals are limited.
Greasy food does not cure a hangover or make the body clear alcohol faster. A meal you tolerate may ease hunger, but recovery still requires time.
Hangover symptoms can include dehydration, stomach irritation, disrupted sleep, inflammation and impaired attention. One food cannot reverse all of these processes.
Safety note: Alcohol plus acetaminophen can harm the liver, while aspirin and ibuprofen can worsen stomach irritation or bleeding risk. Repeated severe hangovers can signal hazardous drinking rather than a need for a better remedy.
Talk to a healthcare professional if: Call emergency services for confusion, inability to wake, slow or irregular breathing, seizures, blue or pale skin, or repeated vomiting. Seek medical advice for persistent vomiting, withdrawal symptoms or concern about alcohol use.
Choose fluids and food that you can comfortably tolerate, but do not rely on a heavy breakfast, coffee, another drink or an IV service as a cure.
Rest, avoid more alcohol, sip fluids and eat a simple balanced meal if hungry. Do not drive, operate machinery or care for others if attention or coordination is impaired.
