The best foods for a hangover are ones that rehydrate you, stabilize your blood sugar, and give your liver the raw materials it needs to finish processing alcohol. Eggs, bananas, oatmeal, and broth-based soups all check multiple boxes. But timing matters too: what you eat before and during drinking can be just as important as what you eat the next morning.
Why Hangovers Make You Feel So Bad
When your liver breaks down alcohol, the first byproduct is a toxic compound called acetaldehyde. This substance is responsible for a large share of hangover symptoms, including nausea, headache, and that general feeling of being poisoned. Your body eventually converts acetaldehyde into harmless acetic acid, but that process takes time, and if you drank more than your liver could keep up with, the toxic intermediate builds up.
Alcohol also drops your blood sugar, dehydrates you by suppressing a hormone that tells your kidneys to hold onto water, and irritates your stomach lining. That’s why a hangover hits you from so many directions at once: fatigue, shakiness, nausea, headache, and brain fog are all coming from different mechanisms. The right foods target these problems individually.
Eggs
Eggs are one of the most frequently recommended hangover foods, and the reasoning is solid. They’re rich in an amino acid called L-cysteine, which reacts directly with acetaldehyde, the toxic byproduct your liver produces when it metabolizes alcohol. Researchers at the University of Helsinki found that L-cysteine alleviates hangover symptoms by helping neutralize this compound. Eggs also provide B vitamins that alcohol depletes and are gentle enough on the stomach for most people to keep down. Scrambled or poached tends to be easier to eat than fried when you’re already feeling queasy.
Bananas and Avocados
Alcohol acts as a diuretic, which means you lose electrolytes along with all that extra fluid. Potassium is one of the minerals that drops the most, and low potassium contributes to muscle weakness, fatigue, and that shaky feeling. A single banana provides around 400 mg of potassium, and half an avocado provides roughly the same. Both are also easy on an irritated stomach, which matters when nausea is part of the picture.
Oatmeal and Whole Grain Toast
Alcohol interferes with your body’s ability to maintain steady blood sugar, which is why you might feel shaky, weak, and mentally foggy the morning after. Complex carbohydrates like oatmeal, whole grain toast, and brown rice digest slowly, providing a gradual rise in blood glucose rather than a spike and crash. Whole grains and legumes are digested more slowly than refined carbs, making them a better choice for sustained energy during recovery.
If you haven’t been eating much fiber lately, go easy. A sudden jump in high-fiber foods can cause gas and bloating, which is the last thing you want on top of an already upset stomach. A bowl of plain oatmeal with a banana is a good middle ground: enough slow-release carbs to stabilize blood sugar without overwhelming your gut.
Broth and Soup
Chicken broth, miso soup, or pho hit several targets at once. They deliver water, sodium, and potassium in a form that’s easy to absorb. The warm liquid is soothing for a stomach that’s been irritated by alcohol, and the salt helps your body actually retain the fluids you’re drinking rather than losing them immediately. Bone broth also contains glycine, another amino acid that supports liver function. If you can manage it, adding some rice noodles or crackers gives you those slow-digesting carbs your blood sugar needs.
Foods Rich in Omega-3 Fats
Alcohol triggers inflammation throughout the body, including in the brain, which contributes to that foggy, sluggish feeling. Omega-3 fatty acids help counter this by calming inflammatory pathways and reducing the production of inflammatory signaling molecules. Salmon, sardines, and mackerel are the richest food sources. If fish sounds unbearable the morning after, walnuts or chia seeds mixed into oatmeal are a milder alternative. You won’t reverse brain inflammation with a single serving, but omega-3s support the recovery process rather than working against it.
Honey and Fruit
There’s a persistent idea that honey speeds up alcohol metabolism because of its fructose content. Research published in The Lancet showed that large doses of fructose (around 90 grams, far more than a few spoonfuls of honey) did increase the rate of alcohol metabolism. But even at those high doses, there was no significant improvement in how people actually felt or performed. So while a drizzle of honey on toast or some fruit alongside your eggs won’t hurt, and the natural sugars can help with low blood sugar, don’t expect honey to clear alcohol from your system in any meaningful way.
Watermelon, oranges, and berries are worth eating for their water content and vitamins. Watermelon is about 92% water, making it a surprisingly effective way to rehydrate when plain water feels hard to get down.
What to Avoid
Greasy food is the classic hangover “cure,” but the timing is usually wrong. A fatty meal before drinking can slow alcohol absorption and genuinely reduce how drunk you get. Eating greasy food the morning after, when your stomach lining is already irritated, is a different story. High-fat foods can trigger or worsen gastritis symptoms, and alcohol itself is already a known gastritis trigger. If your stomach is churning, piling on bacon and hash browns may make things worse, not better.
Coffee is another common instinct. Caffeine can help with a headache, but it’s also a diuretic, which works against your rehydration efforts. If you’re a regular coffee drinker and skipping it would give you a withdrawal headache on top of everything else, a small cup alongside plenty of water is reasonable. Just don’t rely on it as the fix.
Spicy food, citrus juices on an empty stomach, and carbonated drinks can all aggravate an already sensitive digestive system. Stick with bland, easy-to-digest options until your stomach settles.
Timing Makes a Big Difference
Eating before you drink is significantly more effective than trying to eat your way out of a hangover the next day. Food in your stomach slows the rate at which alcohol reaches your small intestine, where most absorption happens. According to Johns Hopkins University, consuming food while drinking increases the rate of alcohol elimination from the bloodstream by 25 to 45 percent. That’s a substantial difference.
The ideal pre-drinking meal combines protein, fat, and complex carbs: think a chicken and rice bowl, a sandwich with avocado, or eggs with whole grain toast. This combination slows gastric emptying, meaning alcohol enters your system more gradually and your liver has a better chance of keeping up.
The morning after, your goals shift. You’re no longer trying to slow absorption. Instead, you’re trying to rehydrate, restore blood sugar, replenish lost nutrients, and give your liver the amino acids it needs to finish clearing acetaldehyde. That’s where eggs, bananas, oatmeal, and broth come in. Eating something within an hour or two of waking, even if it’s small, jumpstarts this recovery process. Waiting until the afternoon to eat because you feel too nauseous only extends the misery.
