Eating around alcohol genuinely affects how drunk you get, how fast you get there, and how rough the next morning feels. The mechanisms are simple: food slows alcohol absorption, supports your blood sugar, and replaces nutrients lost to drinking. The choices that work are mostly the unsexy ones. This article is part of our Hangovers hub, the complete guide to preventing and recovering from a hangover.
This article covers what to eat in three windows: before drinking, during, and the morning after. The advice is evidence-based where evidence exists, and explicitly flagged when it’s traditional rather than tested.
# Why food matters around alcohol
Alcohol absorbs primarily through the small intestine. The faster it gets there, the faster you get drunk, and the more your liver has to handle at once. Food does three useful things:
It slows gastric emptying. Alcohol sits in your stomach longer, reaching the small intestine more gradually. Peak blood alcohol arrives lower and later. This is the main mechanism, and it’s substantial. The same six drinks on an empty stomach versus after a meal can produce a 30-50% difference in peak blood alcohol concentration.
It buffers acid and irritation. Alcohol irritates the stomach lining; food cushions this and reduces the nausea risk during and after drinking.
It maintains blood sugar. Alcohol disrupts blood sugar regulation, particularly when consumed without food. Low blood sugar amplifies hangover symptoms, especially anxiety and headache.
What food doesn’t do: speed up alcohol metabolism. Once the alcohol is in your bloodstream, your liver processes it at roughly the same rate regardless of what you ate. Food is a delay tactic, not an enhancer.
# Before drinking: what to eat 1-2 hours ahead
The goal of a pre-drinking meal: slow your absorption and stabilise your blood sugar before alcohol arrives. The science points clearly at meals with three components:
Protein. Slows gastric emptying more than carbs alone and supports steady blood sugar. Eggs, chicken, fish, beef, tofu, lentils, beans, Greek yoghurt.
Fat. Slows gastric emptying further, particularly when paired with protein. Avocado, olive oil, butter, cheese, nuts, fatty fish like salmon.
Complex carbohydrates. Provide the slow-release glucose that keeps blood sugar stable through the session. Whole grains, oats, sweet potato, brown rice, dense bread.
Some practical examples that hit all three:
- A burger with cheese and a side of fries
- Salmon with rice and avocado
- Pasta with meat sauce and some olive oil
- Chicken curry with rice and yoghurt
- A proper sandwich (turkey, cheese, mayo on substantial bread)
What to avoid pre-drinking:
- Sugary carbs alone (white bread, sugary cereals): produce a blood sugar spike followed by a crash that drinking will worsen
- Pure light carbs without protein: pasta in white sauce alone digests too fast to provide much buffer
- Skipping eating entirely: the worst single thing you can do for hangover severity
# During drinking: snacks that help
If your session is going to run more than 3-4 hours, mid-session food helps maintain the buffering effect. The pre-drink meal’s gastric-emptying delay wears off after a few hours; topping up keeps it going.
What works:
Salty snacks. Crisps, peanuts, olives, pretzels. Replaces sodium your kidneys are flushing alongside the water.
Cheese and bread combinations. Hits protein and complex carbs, slows things down further.
A real food break. If you can step away from drinking for 30 minutes to eat actual food (a plate of nachos, a kebab, dim sum, late-night noodles), you reset some of the buffering AND slow your overall pace. Both are good.
The salty bar snacks long associated with drinking aren’t there by accident. The traditional pairing of beer with pretzels, gin with olives, or whisky with cheese isn’t just culture; the salt and protein offset some of the dehydration and gastric emptying. The pubs of 200 years ago figured this out before nutritional science did.
# The “drink milk before going out” myth
A persistent piece of folklore: drink a glass of milk before going out and you won’t get hangovers. This doesn’t really work for the reasons people claim.
The theory: milk “coats your stomach” and prevents alcohol absorption. Reality: milk does slow absorption a little, just like any fatty/protein-rich food. It doesn’t form a magical barrier. A proper meal does this much better than a single glass of milk.
If you want the milk to do anything useful, drink it as part of a real meal. On its own, with no other food, it provides limited benefit. Whole milk works better than skim because the fat content is the active ingredient.
Same applies to “lining your stomach” with various oils, butter, or other folk remedies. They work to the extent they’re food. They’re not magical.
# What to eat the morning after
Hangover nausea makes food unappealing. Push through with something simple. The goal is to raise blood sugar, replace electrolytes, and provide gentle nutrients without overloading your already-irritated stomach.
What works:
Something starchy and easy on the stomach. Toast, plain crackers, plain rice, plain pasta, oatmeal. Carbs raise low blood sugar gently.
Eggs. Protein, plus they contain cysteine, an amino acid that helps your liver process the remaining acetaldehyde. The “eggs help with hangovers” claim has some real biochemistry behind it.
Bananas. Potassium, easy on the stomach, mild sweetness without overload. Long associated with hangovers, and the potassium replacement is real.
Honey on toast. Some evidence that fructose helps speed alcohol metabolism. Honey on toast is a classic British hangover breakfast and it has more biochemical justification than most folk remedies.
Bone broth or miso soup. Salt, fluids, easy on the stomach. The “salty broth helps a hangover” tradition shows up across cultures (Vietnamese pho, Korean haejangguk, Mexican menudo, Japanese miso soup) and it actually works for the salt and warm-fluid reasons.
Apple, watermelon, oranges. Fruit with high water content is gentle and provides some sugars without too much intensity.
What to avoid:
Heavy greasy food first thing. The “fry-up cures a hangover” idea is folklore. A full English with bacon, sausages, beans, and fried bread is a heavy load on a stomach that’s already irritated. Most people who report it “working” are noticing the meal feeling better than the empty-stomach nausea, not actually neutralising anything. By an hour later, the heavy fat content can make nausea worse.
Sugary sweet drinks. Smoothies, fruit juice, sugary coffee drinks. Spike blood sugar, then crash it, leaving you worse off. If you want fruit, eat the actual fruit.
More alcohol (“hair of the dog”). It postpones the hangover by extending intoxication, but it doesn’t cure anything. The hangover resumes worse later. We cover this in Hangover Cures That Don’t Work.
# Specific food-and-hangover claims worth examining
A few things people say, with honest assessments:
# “Eat a banana before bed”
The potassium replacement is mildly real. The “before bed” timing is mostly about hoping you’ll wake up less depleted. Modest benefit, easy to do, no downside. Worth doing if you remember.
# “Drink Pedialyte / Liquid IV / oral rehydration”
These actually work and have real evidence behind them. Better than plain water for replacing the salts your kidneys flushed. We cover this in Electrolytes and Hangovers.
# “Coconut water is a natural hangover cure”
Coconut water is fine. It’s natural, has electrolytes, and does help with rehydration. It’s not a “cure,” but it’s a reasonable hydration drink. The marketing oversells it; the actual product is decent.
# “Greasy fries / kebab / pizza on the way home”
Most cultures have a late-night fast-food tradition associated with drinking. It works partly through actually being food (carbs and fat help), partly through the warmth and salt, and partly through cushioning the stomach as you transition to sleeping. It’s not magic, but it’s not nothing.
# “Eat a tablespoon of olive oil before going out”
Folk remedy. The oil does slow gastric emptying somewhat. So does eating actual food, with the bonus of also providing other nutrients. Eat a meal instead.
# What about avoiding food?
A few people deliberately don’t eat before drinking, sometimes because they’re trying to lose weight, sometimes because they want to feel drunk faster on less alcohol. This is a worse strategy than it sounds for two reasons:
- The hangover will be substantially worse for the same alcohol volume
- The judgment-impairing effects come on faster and harder, including the judgment about how much more to drink
If you’re managing alcohol calories specifically, eat smaller portions of the right foods rather than skipping food entirely. We cover the calorie math in our Alcohol Calories hub when those articles populate.
# How AlcoLog tracks the calorie side
AlcoLog logs every drink with its calorie content auto-filled from the catalogue (273 drinks across 87 size presets, with editable values). The session summary and end-of-session review show total alcohol calories, so you can balance drinking and food calories deliberately rather than guessing.
Over time, the History view’s monthly cards show monthly alcohol calorie totals, and the Trend graph lets you select calories as the metric to see your trajectory. This is purely the alcohol-calorie side; food tracking lives in other apps (and Apple Health if you sync that, which AlcoLog can write drinks to).
