If you have gastroenteritis, or the “stomach flu,” not many foods sound appetizing.

While your churning stomach and bowels won't be able to tolerate much, soup for an upset stomach is usually a good choice. Here's a closer look at which soups to reach for when recovering from the stomach flu, and which might make your symptoms worse.

Broth-Based Soup: The Best Soup for Stomach Bug

The nausea, vomiting, and diarrhea that come with gastroenteritis will certainly make you lose your appetite. But once you're able to keep liquids down, it's important to try to eat something to replenish lost nutrients and prevent dehydration.

Broth-based soups are a good option, as they're high in water content and help replace fluids.

 Examples of easy-to-digest broth-based soups include:
  • Chicken noodle soup
  • Vegetable soup
  • Chicken and rice
  • Miso soup
Adding ginger to your soup may offer additional benefits, as it's been shown to help relieve nausea and vomiting.

Broth-based soups also contain a lot of sodium, an electrolyte that quickly depletes through the vomiting and diarrhea that accompany gastroenteritis.

 One cup of a standard canned version of chicken noodle soup has 691 milligrams of sodium, or almost 30 percent of the recommended daily dose.

 However, be mindful of your sodium intake if you have high blood pressure, heart disease, kidney disease, or any other condition where you need to restrict sodium.
Additionally, broth-based soups don't have the high-fat content of creamy soups, such as cream of tomato or cream of chicken. High-fat foods can be hard to digest, especially when your stomach is healing from inflammation, so it's best to skip these soup varieties.

Also avoid spicy soups when you're healing from gastroenteritis, as bland recipes are easier on the stomach.

 If it's a homemade recipe, just leave out the chili flakes or other spicy ingredients.

Other Foods to Consider for the Stomach Flu

If you've successfully eaten broth-based soups while recovering from gastroenteritis and want to try some other foods, consider those that are soft, bland, and easy on the stomach.

These include those in the BRAT diet:

  • Bananas
  • Rice
  • Applesauce
  • Toast
In addition to the BRAT diet, other foods that can be easy to digest with the stomach flu include:

  • Potatoes
  • Oatmeal
  • Jello
  • Popsicles
  • Watermelon
  • Whole grains like bread and pasta
  • Squash
Importantly, make sure to avoid foods and drinks that can irritate your already overburdened digestive tract, such as:

  • Caffeine
  • Alcohol
  • Greasy foods
  • Fatty foods
  • Spicy foods
  • Sugary foods and drinks
  • Dairy

When Will I Feel Better With the Stomach Flu?

In most healthy people, gastroenteritis resolves in one to three days, but can last up to a week or two in severe cases.

The condition isn't usually harmful and typically clears up on its own without the need for medical treatment. However, in cases of severe dehydration, you may need medical care and hospitalization.

Seek care right away if you experience the following symptoms:

  • Vomiting blood
  • Unable to keep liquids down for 24 hours
  • Bloody stool
  • Fever above 104 degrees F
  • Severe abdominal pain or pain in the rectum
  • Signs of dehydration, including excessive thirst, dizziness, extreme fatigue, and little-to-no urine

The Takeaway

  • Broth-based soups, such as chicken noodle, vegetable soup, or miso soup, are excellent options for replenishing fluids and electrolytes when recovering from gastroenteritis.
  • Avoid creamy, high-fat and spicy soups, which can further irritate the stomach and hinder healing from gastroenteritis.
  • If severe symptoms like vomiting blood or signs of dehydration occur, seek immediate medical attention to address possible complications.
