Whether you’re struggling to swallow with a sore throat or can’t keep anything down with a stomach bug, eating isn’t always your top priority when you’re under the weather.
But “our bodies actually need nourishment when we're sick, so don't avoid eating,” says family physician Dr. Shannon Dowler, a board member of the American Academy of Family Physicians.
In many cases, simply eating whatever appeals to you in the moment is enough to make sure you’re getting at least some nutrients and plenty of fluids. But if you can handle it, some specific foods might ease your symptoms.
With an upset stomach, diarrhea, vomiting, or a combination of all three, you probably don’t feel very hungry or thirsty when you’ve got gastroenteritis. The problem is it’s easy to get dehydrated, says registered dietitian and certified specialist in oncology nutrition Amy Bragagnini, spokesperson for the Academy of Nutrition and Dietetics. Dehydration can be dangerous and may result in headaches, fatigue, dizziness, and other unpleasant symptoms, according to the Cleveland Clinic.
Bragagnini suggests getting plenty of water, coconut water, or electrolyte drinks while you’re battling a stomach bug. Start slowly and add more liquids as you can tolerate them. “Take sips and spoonfuls rather than gulping large quantities of liquids,” Dowler says.
Colds and flu
Upper respiratory infections can zap your appetite, especially if your sense of taste or smell is off. Think about eating foods you find nourishing and comforting—like a cozy broth-based soup, crackers, toast, cereal, rice, or Jell-O—and stick to those, Bragagnini says. “When you’re not feeling good … try to eat things that aren't going to irritate or aggravate your symptoms,” she says.
Peppermint or ginger tea can be soothing, she adds. Broths and teas are also hydrating.
Sore throat
If swallowing is painful, it can be hard to imagine eating much at all. Opt for cold foods and drinks, like freezer pops, ice cream, or yogurt, Dowler says, or anything else “that feels good and soothing on the throat.”
Warm soups can feel nice too, and they pack more nutrients than just water, she adds. Tea with honey can soothe a sore throat too, and may even ease a cough, according to the Mayo Clinic.
Heartburn
Heartburn or acid reflux occurs when the valve connecting your esophagus and your stomach doesn’t keep your stomach acid where it’s supposed to be, according to the National Institute of Diabetes and Digestive and Kidney Diseases.
The first thing to do is determine if you’re eating any food that could be making your symptoms worse. Citrus fruits, spicy foods, acidic foods (like tomatoes), chocolate, caffeine, alcohol, and peppermint can all trigger heartburn, so steer clear of those, Bragagnini says. Also, try not to eat too close to bedtime, Dowler says, as lying down shortly after eating may make it more likely for stomach acid to flow back up your esophagus.
Instead, add some high-fiber, watery foods to your diet, like cucumbers and leafy greens, Dowler says. Low-acid foods like bananas and cauliflower might help you feel better, too.
