When you’re sick, the right foods can ease your symptoms, keep you hydrated, and give your body the fuel it needs to recover faster. What you should reach for depends on what kind of sick you are: a head cold calls for different foods than a stomach bug. But across the board, the priorities are fluids, easy-to-digest calories, and enough protein to keep your immune system working.
Chicken Soup Genuinely Helps
Chicken soup isn’t just comfort food. A well-known lab study published in the journal Chest found that traditional chicken soup significantly slowed the movement of white blood cells called neutrophils, which drive the inflammation behind stuffy noses, sore throats, and that overall “sick” feeling. The effect was concentration-dependent, meaning more soup produced a stronger anti-inflammatory response. Researchers concluded that this mild anti-inflammatory action could explain why chicken soup has been a go-to cold remedy for centuries.
Beyond the biology, soup checks several practical boxes at once. The warm broth keeps you hydrated and can loosen nasal congestion. The chicken provides protein. The vegetables add vitamins. And it’s easy to get down when you don’t feel like eating much. Homemade versions with carrots, celery, onion, and garlic tend to be more nutrient-dense than canned, but any version is better than skipping a meal.
Honey for Coughs and Sore Throats
If a persistent cough is keeping you up at night, honey is one of the most effective remedies available. A clinical trial comparing honey to a common over-the-counter cough suppressant found that honey performed just as well at reducing nighttime coughing and improving sleep. Honey also significantly outperformed no treatment at all. A spoonful before bed, swallowed slowly so it coats the throat, is the simplest approach.
Honey works partly as a physical barrier, soothing irritated throat tissue and suppressing the cough reflex. It also has mild antibacterial properties. One important exception: never give honey to children under 12 months old due to the risk of infant botulism.
What to Eat With a Stomach Bug
When you’re dealing with nausea, vomiting, or diarrhea, the old advice was to stick strictly to the BRAT diet: bananas, rice, applesauce, and toast. Those foods are still fine starting points because they’re bland and unlikely to irritate your stomach. But Harvard Health notes there’s no research showing BRAT is superior to other gentle foods, and restricting yourself to just those four items for more than a day or two can leave you short on the protein and nutrients your body needs to recover.
A better approach is to start with BRAT-style foods when your stomach is at its worst, then expand as soon as you can tolerate it. Good additions include brothy soups, oatmeal, boiled potatoes, crackers, and unsweetened dry cereal. Once things settle further, work in cooked squash, cooked carrots, sweet potatoes without skin, avocado, skinless chicken or turkey, fish, and eggs. These are all easy to digest but provide the protein and micronutrients that plain toast and white rice lack.
Ginger is worth keeping on hand if nausea is your main symptom. Clinical trials have used doses ranging from 250 mg to 1 gram per day, split into three or four servings, with no added benefit from going higher. Fresh ginger steeped in hot water as a tea is a simple way to get it, though ginger chews and ginger ale with real ginger (check the label) also work.
Prioritize Protein During Recovery
Your body burns through protein faster when it’s fighting an infection. Immune cells are built from protein, and fever increases your metabolic rate, which accelerates muscle breakdown if you’re not eating enough. Research on nutrition during acute infection suggests that adults need roughly 1.5 to 2 grams of protein per kilogram of body weight per day to maintain a positive nitrogen balance, meaning your body is rebuilding faster than it’s breaking down. For a 150-pound person, that works out to about 100 to 135 grams of protein per day.
That’s a lot more than most people eat on a normal day, let alone when they feel terrible. You don’t need to hit those numbers perfectly, but the takeaway is clear: don’t just sip broth and nibble crackers for days on end. Work in eggs, yogurt, chicken, fish, or a protein smoothie as soon as your appetite allows. Greek yogurt is especially useful because it’s high in protein, cool on a sore throat, and contains probiotics that can support gut health during and after illness.
Zinc Can Shorten a Cold
Zinc lozenges have shown some ability to reduce how long a cold lasts, though the evidence is inconsistent enough that the Mayo Clinic notes researchers still aren’t sure of the ideal dose or timing. The upper safe limit for adults is 40 mg per day. Starting zinc lozenges within 24 hours of your first symptoms appears to matter more than the total dose. If you’d rather get zinc from food, oysters are the richest source by far, followed by red meat, chickpeas, cashews, and pumpkin seeds.
Stay Hydrated, but Not Just With Water
Fever, sweating, vomiting, and diarrhea all drain fluids and electrolytes. Plain water helps, but it doesn’t replace the sodium and potassium you’re losing. Better options include broth (which is naturally salty), coconut water, diluted fruit juice, or an oral rehydration solution. Herbal teas count toward your fluid intake too, and warm liquids can relieve congestion and soothe a raw throat.
A practical way to monitor hydration: check your urine color. Pale yellow means you’re doing fine. Dark yellow or amber means you need more fluids. If you’re vomiting and can’t keep liquids down, take small sips every few minutes rather than trying to drink a full glass at once.
Dairy Doesn’t Make Congestion Worse
You may have heard that milk increases mucus production. It doesn’t. The Mayo Clinic confirms that drinking milk does not cause your body to make more phlegm. What actually happens is that milk and saliva mix to create a slightly thick coating in the mouth and throat, which some people mistake for extra mucus. Studies in children with asthma found no difference in respiratory symptoms whether they drank dairy milk or soy milk.
This matters because dairy is one of the easiest ways to get calories and protein when you’re sick. Yogurt, milk-based smoothies, and even ice cream can be genuinely helpful if a sore throat is making it hard to eat solid food. Avoiding dairy out of a misplaced fear of mucus can cost you nutrition at a time when your body needs it most.
Foods to Avoid While Sick
Some foods are harder on your body when you’re already struggling. Alcohol suppresses immune function and dehydrates you. Caffeine in large amounts also dehydrates, though a single cup of coffee or tea is fine if it helps you feel human. Very spicy foods can irritate an already inflamed throat or upset stomach. Greasy, heavy, or fried foods sit in the stomach longer and can worsen nausea.
High-sugar foods like candy and soda provide calories but little else, and large sugar loads can temporarily impair white blood cell function. If you want something sweet, fruit or honey in tea is a better choice.
A Simple Sick-Day Eating Plan
- Morning: Oatmeal made with milk, a banana, and a drizzle of honey. Ginger tea if you’re nauseous.
- Midday: Chicken soup with vegetables. Crackers on the side if your stomach is sensitive.
- Afternoon: Greek yogurt with berries, or a smoothie made with yogurt, frozen fruit, and a spoonful of honey.
- Evening: Scrambled eggs with toast, or baked fish with mashed sweet potato.
- Throughout the day: Broth, herbal tea, water with electrolytes, and zinc lozenges if you’re fighting a cold.
The goal isn’t a perfect diet. It’s getting enough fluids, enough protein, and enough calories to let your immune system do its job. Eat what you can tolerate, expand your choices as your appetite returns, and don’t force yourself to choke down foods that make you feel worse.
