Wondering what to eat when sick? Here are the best foods for colds, flu, sore throats and stomach bugs, plus easy sick meals you can make with one pot.
Foods to Eat When Sick: What Actually Helps (and What to Skip)
There's a particular kind of misery that comes with being ill. You're tired, your head hurts, your throat feels like sandpaper, and the last thing you want to do is stand in a kitchen. Food becomes a problem to solve rather than something to enjoy. But your body is doing expensive work right now, fighting off whatever got in, and it needs fuel and fluids to keep doing it.
The good news is that the best foods to eat when sick are usually the simplest ones. No special ingredients, no complicated cooking. Most of what helps is already in your kitchen or a short trip to the shop away.
This guide walks through what to eat when sick, which foods suit which symptoms, what to avoid, and a few easy sick meals you can put together even when you feel terrible.
Why You Lose Your Appetite When You're Ill
Losing interest in food during an illness is normal. When your immune system kicks into gear, it releases signalling chemicals called cytokines, and one of their side effects is appetite suppression. Fever also slows digestion, which is part of why heavy meals sit badly.
That's fine for a day. It's less fine over three or four days, because recovery needs protein, calories, fluids and minerals. The practical answer isn't to force down a full dinner. It's to eat small, often, and choose things that are gentle on your stomach and easy to swallow.
A useful rule while you're unwell: something is better than nothing, and liquids matter more than solids.
The Best Foods to Eat When Sick
1. Broth and clear soups
If there's one thing to reach for first, it's broth. Chicken, beef or vegetable, it doesn't matter much. Broth delivers water and sodium together, which is exactly what your body needs when a fever or sweating has pulled fluid out of you. It's warm, it's easy to sip, and it doesn't ask anything of your digestion.
Bone broth adds a bit of protein and collagen, though the research on collagen supplementation is thinner than the marketing suggests. Plain broth does the main job well enough.
2. Chicken soup
Chicken soup earned its reputation honestly. Research has found that chicken soup can slow the movement of neutrophils, the immune cells linked to inflammation in the upper airways, which may explain why it seems to ease congestion and general cold misery. The steam helps clear your nose, the warm liquid soothes a raw throat, and you get protein, vegetables and salt in one bowl.
It also happens to be one of the few sick foods people will actually eat when they've stopped wanting anything.
3. Bananas
Soft, bland, and easy to keep down, bananas are a staple of the old BRAT approach (bananas, rice, applesauce, toast) that people turn to after a stomach bug. They provide potassium, an electrolyte you lose quickly through vomiting or diarrhoea, and their soluble fibre can help firm up loose stools.
Dietitians no longer recommend sticking to BRAT alone for long, since it's low in protein and nutrients, but the individual foods on that list are still a sensible starting point when your stomach is unhappy.
4. Oatmeal
Oats are cheap, filling, and about as gentle as food gets. A bowl of plain porridge gives you slow-release carbohydrates when your energy is gone and beta-glucan fibre that feeds gut bacteria. Make it with water if dairy bothers you while ill, and stir in a spoon of honey and a sliced banana.

5. Yoghurt and kefir
Live-culture yoghurt supplies protein and probiotics, and it's cold, which feels good on an inflamed throat. Probiotics have some evidence behind them for shortening the duration of common colds and for reducing antibiotic-related diarrhoea. If dairy leaves you phlegmy or nauseated, skip it. That reaction varies from person to person and there's no prize for pushing through.
6. Ginger
Ginger is one of the most reliable natural remedies for nausea, with decent evidence behind it for pregnancy sickness and post-surgical nausea. Grate a thumb of fresh ginger into hot water, add lemon and honey, and sip it slowly. Ginger tea is one of the few things that helps when you can't face any solid food at all.
7. Honey
Honey coats the throat and has genuine antibacterial properties. It's also a well-supported cough suppressant, and several studies have found it works at least as well as some over-the-counter cough syrups for night-time coughing in children over one. Stir it into tea, take it off a spoon, or drizzle it over porridge.
One firm safety point: never give honey to a baby under 12 months, because of the risk of infant botulism.
8. Garlic
Garlic contains allicin, a sulphur compound with antimicrobial activity, and some studies suggest regular garlic intake may reduce how often people catch colds. Crush it and let it sit for ten minutes before cooking to let the allicin form. Adding a couple of crushed cloves to your soup costs nothing and adds real flavour when your taste buds have gone flat.
9. Citrus fruit and vitamin C sources
Vitamin C won't stop you catching a cold, despite decades of folklore. What the evidence does support is a modest reduction in how long a cold lasts when you're already taking it regularly. Oranges, kiwi, bell peppers, strawberries and broccoli all deliver plenty.
If citrus stings a raw throat, and it often does, go for kiwi or melon instead.
10. Eggs
When you can manage something more substantial, scrambled eggs are ideal. They're soft, quick, and packed with complete protein plus zinc, selenium and vitamin D. Protein matters more than people assume during illness, since your immune system builds antibodies from amino acids.
11. Sweet potatoes
Mashed sweet potato is soft, naturally sweet, and loaded with beta-carotene, which your body converts to vitamin A. Vitamin A supports the mucous membranes lining your nose, throat and gut, the first barrier against infection.
12. Herbal teas
Peppermint tea helps with nausea and bloating. Chamomile is calming and may help you sleep, which is the single most underrated part of recovery. Any warm drink produces steam that loosens nasal congestion for a while.
13. Coconut water and oral rehydration solution
After vomiting or diarrhoea, plain water isn't enough on its own, because you've lost sodium and potassium along with the fluid. Coconut water helps, but a proper oral rehydration solution from a pharmacy is far better matched to what you've lost and is the standard treatment recommended worldwide.
14. Avocado
Soft, calorie-dense, and neutral in flavour, avocado gets energy into you when appetite is low. Healthy fats also help your body absorb fat-soluble vitamins. Mash it onto toast when you can't face cooking.
15. Spicy foods, but only for congestion
Capsaicin, the compound that makes chillies hot, thins mucus and gets your nose running, which temporarily clears blocked sinuses. A bowl of spicy pepper soup is a genuinely effective decongestant. Avoid it entirely if your problem is a sore throat, acid reflux or an upset stomach, where heat will make things worse.
What to Eat for Specific Symptoms
Sore throat: Cold or lukewarm, smooth, soft. Yoghurt, smoothies, ice lollies, mashed potato, warm (not scalding) broth, honey in tea. Skip anything sharp, crunchy, acidic or very hot.
Nausea and vomiting: Stop solids for a few hours, then start with small sips of an oral rehydration solution. Once that stays down, try dry crackers, plain toast, banana or plain rice in small amounts.
Diarrhoea: Rehydrate first. Then bland, low-fibre starches: white rice, boiled potatoes, toast, bananas. Reintroduce normal food gradually over a day or two rather than jumping straight back to rich meals.
Fever: You lose a lot of water through sweating, so fluids come first. Soups, broths, diluted juice, water. Small frequent snacks beat large meals.
Blocked nose and cough: Steam and warmth. Chicken soup, ginger tea, honey, a touch of chilli if your stomach can handle it.
Things to Avoid While You're Sick
- Alcohol. It dehydrates you, disrupts sleep and interferes with immune function, and it interacts badly with plenty of common medications.
- Very greasy or fried food. Fat slows gastric emptying, which makes nausea worse.
- Heavily sugary drinks. High-sugar liquids can worsen diarrhoea by pulling water into the gut.
- Excess caffeine. A cup of tea is fine. Several strong coffees will work against your hydration.
- Anything rough or scratchy while your throat is inflamed: crisps, toast crusts, dry crackers, nuts.
Three Easy Sick Meals
One-pot ginger chicken soup. Simmer chicken pieces in water with a chopped onion, three crushed garlic cloves, a thumb of sliced ginger and salt for 30 minutes. Add chopped carrot and celery for the last 10. Squeeze in lemon at the end. Makes enough for two or three days.
Savoury oats. Cook oats in broth instead of water, top with a soft-boiled egg and a pinch of salt. Ready in six minutes and far more satisfying than the sweet version when you're not craving sugar.
Banana and yoghurt smoothie. Blend one banana, a cup of plain yoghurt, a spoon of honey and a splash of milk. Cold, soothing, and it delivers protein and calories when chewing feels like too much effort.
Frequently Asked Questions
Should you starve a fever?
No. The old saying "feed a cold, starve a fever" has no basis in evidence. Your body needs energy and fluid during a fever more than usual, not less.
How long can I go without eating while sick?
Missing meals for a day while you're acutely unwell is generally not a concern for an otherwise healthy adult, as long as you're drinking. Beyond that, or sooner if you have diabetes or another chronic condition, speak to a doctor.
Is dairy bad when you have a cold?
Studies haven't found that milk increases mucus production. Some people feel it thickens their phlegm, so go by how you personally respond rather than the rule.
When to Stop Googling and Call a Doctor
Food helps with comfort and recovery, but it isn't treatment. Get medical advice if you have a high fever lasting more than three days, difficulty breathing, chest pain, confusion, signs of dehydration such as very little urine or dizziness on standing, persistent vomiting that stops you keeping fluids down, or symptoms that improve and then suddenly get worse.
This article is general information, not medical advice. If you're managing a chronic illness, pregnant, caring for a young child, or taking regular medication, check with a healthcare professional about your particular situation.
The Short Version
The best foods to eat when sick are warm, soft, hydrating and easy to digest. Broth, chicken soup, bananas, oats, yoghurt, ginger, honey and eggs cover nearly every situation. Drink more than feels necessary, eat small amounts often instead of forcing full meals, and give yourself permission to rest while your body does its work.
You won't cure a virus with a bowl of soup. But you'll feel a great deal better while you wait it out, and that counts for more than people give it credit for.
