What to Snack on When Sick: Foods That Help

The best snacks when you’re sick depend on your symptoms, but a few universals apply: your body needs more calories than normal (your metabolic rate rises 8 to 10% for every degree of fever), you lose fluids faster, and your appetite is probably low. That means ideal sick-day snacks are easy to eat, calorie-dense enough to matter, and packed with fluids or nutrients that support recovery.

Here’s what actually helps, organized by what you’re dealing with.

Best Snacks for Nausea and Vomiting

When your stomach is unsettled, bland and low-fiber foods are easiest to keep down. The classic BRAT foods (bananas, rice, applesauce, toast) still work well in the short term, though they’re not nutritionally complete enough to rely on for more than a day or two. As soon as you can tolerate more, expand to other gentle options: mashed potatoes without the skin, plain oatmeal, canned peaches, or plain yogurt.

Ginger is one of the most evidence-backed natural remedies for nausea. Its active compounds block serotonin receptors in the gut, the same pathway that many prescription anti-nausea medications target. Roughly 1 gram per day (about half a teaspoon of ground ginger) for three or more days has been shown to reduce vomiting. Ginger tea, ginger chews, or even flat ginger ale made with real ginger can all deliver enough to help. Nibbling on a few plain crackers alongside ginger tea is a solid combination when nothing else sounds appealing.

Snacks That Help With a Sore Throat or Cough

Honey is a surprisingly effective cough suppressant. In clinical studies, it performed as well as diphenhydramine, a common over-the-counter cough ingredient. A half teaspoon to one teaspoon (about 2.5 to 5 milliliters) can coat and soothe an irritated throat. Stir it into warm water or herbal tea, drizzle it over oatmeal, or just eat it straight off the spoon.

Cold, soft snacks also feel good on a raw throat. Frozen fruit bars, smoothies, yogurt, and applesauce all go down easily without scratching inflamed tissue. Warm broth (which is 92% water) works from the other direction, loosening congestion while delivering salt and fluids. Avoid anything crunchy, acidic, or spicy until your throat feels better.

Staying Hydrated Through Food

Fever, sweating, vomiting, and diarrhea all drain fluids fast. Drinking water matters, but water-rich snacks pull double duty by delivering hydration along with vitamins and electrolytes. Some of the highest-water-content foods you can snack on:

  • Watermelon (92% water) with vitamin C and antioxidants
  • Strawberries (92% water)
  • Cucumber slices (96% water)
  • Tomatoes (94% water) with potassium and vitamin C
  • Kiwi (90% water)
  • Bell peppers (92% water)
  • Broth-based soups (92% water) with sodium that helps your body retain fluids

If you can only manage small bites, watermelon and cucumber are two of the easiest options. They require almost no chewing and slide down a sore throat without trouble. Popsicles made from real fruit juice are another low-effort way to get fluids in when drinking feels like a chore.

Protein Snacks for Recovery

Your immune system runs on protein. During a mild to moderate illness, your body needs roughly 0.8 to 1.2 grams of protein per kilogram of body weight per day. For a 150-pound person, that’s about 55 to 82 grams daily. When your appetite is suppressed, hitting that number through three meals alone is tough, so protein-rich snacks fill the gap.

Plain Greek yogurt is one of the best options because it’s high in protein (typically 12 to 17 grams per serving), easy on the stomach, and contains live bacterial cultures that may support your recovery. A clinical trial in children with respiratory infections found that a daily probiotic mixture shortened fever duration by two full days compared to placebo (three days versus five). While yogurt delivers lower doses of probiotics than a supplement, it still contributes beneficial bacteria alongside its protein.

Other good protein snacks when you’re sick: scrambled eggs, nut butter on toast, a small bowl of chicken soup, or a simple smoothie blended with milk or a protein-rich base. These are all soft, require minimal preparation, and deliver meaningful protein without being heavy.

Snacks That Support Your Immune System

Zinc is one of the few nutrients with strong evidence for actually shortening a cold. In a pooled analysis of seven clinical trials, zinc lozenges providing more than 75 milligrams of elemental zinc per day shortened cold duration by an average of 33%. That’s roughly a full day or two off the typical cold timeline. Zinc lozenges aren’t exactly a “snack,” but pairing them with zinc-rich foods like pumpkin seeds, cashews, or chickpeas keeps your levels topped up.

Vitamin C from whole foods is easier to absorb than most supplements, and snacking on strawberries, kiwi, bell pepper strips, or orange slices throughout the day delivers a steady supply. These fruits also carry the hydration benefits mentioned above.

What to Skip

Greasy, fried, or heavily spiced foods are harder to digest and can worsen nausea. Sugary snacks like candy or pastries provide quick energy but no meaningful nutrition, and excess sugar can contribute to digestive discomfort when you’re already unwell.

One thing you don’t need to avoid: dairy. The widespread belief that milk increases mucus production has been studied multiple times and consistently debunked. When milk mixes with saliva, it creates a slightly thick coating in the mouth that people mistake for extra phlegm, but it doesn’t actually increase mucus production in the respiratory tract. If yogurt, milk-based smoothies, or cheese sounds good to you, go ahead.

Putting It Together

Sick-day snacking works best as grazing rather than forcing yourself to sit down for a full meal. A practical day might look like ginger tea and plain crackers in the morning, a small bowl of chicken broth with some toast mid-morning, Greek yogurt with honey in the afternoon, and watermelon or a smoothie later on. The goal is frequent, small bites that keep calories, fluids, and protein trickling in without overwhelming a stomach that’s already working overtime.

If you’ve been vomiting, start with the blandest options (plain rice, bananas, dry toast) and add more variety as your stomach settles. Most people can expand back to a normal range of foods within 24 to 48 hours. Prioritize whatever sounds tolerable over whatever sounds “optimal.” When you’re sick, any calories that stay down are good calories.
