Never Eat Greasy Food When You Have A Hangover. Here's Why
Although eating greasy food has long been touted as a hangover cure, it's actually one of the worst things you can do when you're recovering from a hangover. Eating greasy food after a night of drinking may satisfy your appetite, but it won't make you feel any better (via Insider). If anything, it will just end up irritating your stomach.
That's because alcohol and fat are both digested and broken down in the same metabolic pathway. Eating a burger and fries won't absorb any alcohol you consume if you eat it after the fact. The beers or margaritas you drank first will have already been digested by the time you place your order.
However, eating a greasy meal before drinking may actually help prevent a hangover, or at least lessen the severity of it (via Verywell Mind). Eating greasy or fatty food beforehand can slow the absorption of alcohol into the bloodstream and coat your stomach, leading to less irritation in your gastrointestinal tract.
What can you eat to cure a hangover?
While greasy food may not be able to cure a hangover, there are other foods and beverages you can eat and drink to help ease your symptoms. The most important thing you can do to help relieve a hangover is to stay hydrated (via NBC News). Alcohol can cause dehydration, so drinking as much water as possible can help quench your thirst and rehydrate your body.
Eating soup can also help remedy a hangover. Soup is a good food to eat if your stomach is upset. The sodium and potassium in soup can help you retain water and fluids, keeping your body nice and hydrated. Eggs are another great food to eat after a night of drinking (via Greatist). Eggs are rich in vitamin B12, which can help boost your energy levels. They're also full of amino acids, like cysteine and taurine. Cysteine can help rid your body of acetaldehyde, the toxic compound that alcohol gets broken down into, while taurine can help protect your liver.
