When you have COVID, your body needs more calories, more protein, and more fluids than usual to fuel your immune response and prevent muscle loss. The best foods are nutrient-dense, easy to prepare, and gentle enough to eat even when your throat hurts or your appetite has vanished. A fever of 102°F alone causes you to lose about 30 ounces of fluid in 24 hours through sweating, with another 3 ounces lost from coughing and breathing, so hydration is just as important as food.
Fluids Come First
Dehydration is one of the biggest risks during an active COVID infection, especially if you have fever, diarrhea, or vomiting. Aim to drink 2 to 4 ounces of fluid every 15 minutes while you’re awake. Water is fine, but beverages that contain some calories, electrolytes, and minerals are better because they replace what your body is burning through. Sports drinks, oral rehydration solutions, broth, and coconut water all fit the bill.
If you’re vomiting or dealing with diarrhea, add an oral rehydration solution (the kind sold at pharmacies for stomach illness) on top of plain water. Small, frequent sips are easier to keep down than large gulps. Herbal tea, diluted juice, and soup broth all count toward your fluid intake.
Prioritize Protein
Your body breaks down muscle tissue faster during infection, and protein is what rebuilds it. Clinical nutrition guidelines recommend 1.2 to 2 grams of protein per kilogram of body weight per day during COVID recovery. For a 150-pound person, that works out to roughly 80 to 135 grams of protein daily, which is significantly more than most people normally eat.
You don’t need to hit that target perfectly, but it helps to include protein at every meal and snack. Eggs, Greek yogurt, canned tuna, chicken, beans, lentils, cheese, peanut butter, and milk are all solid options. If chewing feels exhausting, a smoothie blended with milk, yogurt, oats, and a banana packs protein and calories into something you can sip from the couch.
Easy Meals When You’re Exhausted
COVID fatigue can make even standing in the kitchen feel like a marathon. Look for meals with no more than five ingredients and minimal cooking time, then get back to resting. The goal is to eat something from a few different food groups (grain, protein, vegetable, fruit, dairy) without turning it into a project.
Some combinations that work well:
- Toast with avocado and a boiled egg
- Bread with peanut butter and banana
- Pasta with canned tuna, tomato sauce, and cheese
- Scrambled eggs with toast
- Baked potato or sweet potato with yogurt and spices
- Quesadilla with canned black beans, corn, and cheese
- Fruit smoothie with milk, yogurt, and oats
- Canned fruit with yogurt or custard
- Cereal with milk and fruit
- Store-bought or homemade soup loaded with vegetables
Frozen vegetables are just as nutritious as fresh and require almost no prep. A bag of frozen mixed vegetables tossed into canned soup or scrambled eggs adds vitamins and minerals with zero effort. If you’re relying on frozen meals from the supermarket, choose options that include at least two servings of vegetables.
What to Eat With a Sore Throat or Nausea
A raw, swollen throat makes crunchy or acidic foods painful. Stick with soft, cool, or room-temperature options: yogurt, oatmeal, mashed potatoes, scrambled eggs, smoothies, and soup with the vegetables cooked until very soft. Warm broth can actually soothe throat pain while keeping your fluid intake up.
If nausea is the bigger problem, go bland. Plain chicken, fish, tofu, rice, and simple crackers are easier for an unsettled stomach to handle. Eat small portions more frequently rather than forcing three full meals. Ginger tea can help settle mild nausea.
When Food Tastes Wrong or Like Nothing
Loss of taste and smell is less common with newer COVID variants, but it still happens. When food tastes flat, adding extra seasoning can help. Try bold herbs, spices, mustard, citrus juice, or a squeeze of lemon. Adding more salt, sugar, butter, or cream than you’d normally use can make bland-tasting food more palatable while you recover.
If food tastes metallic, switching to plastic cutlery and glass cookware can reduce that sensation. When everything tastes too sweet, balance it with tart flavors like orange or lime. If everything tastes too salty or bitter, a drizzle of honey or a bit of sweetener can help even things out. Experimenting with different temperatures (cold yogurt versus warm oatmeal) and textures (smooth pudding versus crunchy toast) can also help you find what’s tolerable.
Foods That Help Fight Inflammation
COVID triggers widespread inflammation, and the foods you eat can either calm that response or make it worse. A pattern resembling the Mediterranean diet, rich in vegetables, fruits, whole grains, olive oil, nuts, and fatty fish, is one of the most effective dietary approaches for managing inflammation.
Fatty fish like salmon, sardines, mackerel, and tuna contain omega-3 fatty acids that directly reduce inflammatory signaling. Nuts, seeds, and canola oil provide a plant-based form of omega-3 along with vitamin E. Colorful fruits and vegetables deliver vitamin C and polyphenols, both of which protect cells from the kind of damage that fuels inflammation. Bell peppers, citrus fruits, berries, and leafy greens are especially rich in these compounds. Even coffee, tea, and dark chocolate contain polyphenols.
Fiber-rich foods like beans, lentils, asparagus, bananas, and whole grains feed the beneficial bacteria in your gut, which play a direct role in immune regulation. Keeping those bacteria well-nourished supports your body’s ability to manage the infection and recover afterward.
What to Avoid
Diets high in ultra-processed foods, added sugars, and inflammatory fats can worsen immune dysfunction and slow recovery. This means cutting back on fast food, sugary drinks, packaged snacks, and fried foods while you’re sick. These foods provide calories without the vitamins, minerals, and protein your immune system is burning through at an accelerated rate.
Alcohol suppresses immune function and dehydrates you, both of which are the opposite of what your body needs right now. Research on post-COVID outcomes found that people who followed a cluster of healthy behaviors, including a high-quality diet and moderate alcohol intake, had a 49% lower risk of developing prolonged symptoms after infection.
What About Vitamin Supplements?
Despite widespread interest in vitamin C, vitamin D, and zinc for COVID, clinical trials have not shown that supplementing with any of them shortens symptoms or improves outcomes. A trial of 8,000 mg of vitamin C daily for 10 days in non-hospitalized COVID patients found no reduction in symptom duration. A similar trial with 50 mg of zinc daily showed the same result. And a study giving hospitalized patients a single massive dose of 200,000 IU of vitamin D found no benefit for length of hospital stay, ICU admission, or survival.
The NIH’s position is that data are currently insufficient to recommend any supplement for preventing or treating COVID. That said, meeting your normal daily requirements for these nutrients through food remains important for general immune function. You just shouldn’t expect megadoses to speed up your recovery.
Calorie Needs During Infection
Your body burns more energy fighting an infection than it does at rest. Nutrition guidelines for COVID patients recommend 25 to 30 calories per kilogram of body weight per day. For a 150-pound person, that’s roughly 1,700 to 2,000 calories. If your appetite is suppressed, which is common, try to eat calorie-dense foods in small amounts throughout the day rather than relying on three full meals. Nut butters, cheese, yogurt, smoothies, and avocado pack a lot of nutrition into small volumes that don’t require a big appetite to get down.
