Chicken broth can help when you have diarrhea, but it works better as a comfort food and supplement to proper rehydration than as a standalone treatment. It replaces some lost sodium, is easy on the stomach, and provides amino acids that support gut repair. However, it lacks the specific balance of sugar and electrolytes needed for true rehydration, which means you shouldn’t rely on it as your only fluid source during a bad bout of diarrhea.
What Chicken Broth Does Well
Diarrhea drains your body of water, sodium, and potassium. Chicken broth is relatively high in sodium, delivering around 250 milliequivalents per liter in its standard form. That translates to roughly 860 mg of sodium per cup for a typical store-bought brand like Swanson. Since sodium helps your body hold onto water rather than letting it pass straight through, sipping warm broth between episodes can slow the cycle of fluid loss.
Broth also goes down easily when solid food sounds unbearable. It requires almost no digestion, which means your already-irritated gut doesn’t have to work hard to process it. For many people, the warmth itself is soothing and can ease the cramping that often accompanies diarrhea.
Amino Acids That Support Gut Repair
Bone broth, specifically broth made by simmering bones for several hours, contains amino acids like glutamine, glycine, proline, histidine, and arginine. These compounds support cellular repair and help maintain the integrity of the gut barrier, which is the lining that controls what passes from your intestines into your bloodstream. When diarrhea is caused by an infection or inflammation, that lining takes a beating. Glutamine in particular serves as a primary fuel source for the cells lining your intestines, helping them regenerate faster.
Standard store-bought chicken broth contains lower concentrations of these amino acids than true bone broth, since it’s typically simmered for less time and with fewer bones. If gut repair is your goal, homemade bone broth or a commercial bone broth (which will be labeled as such) offers more benefit than regular chicken broth.
Why Broth Alone Isn’t Enough for Rehydration
Here’s the important caveat: chicken broth is not classified as an appropriate rehydration fluid by medical guidelines. The reason comes down to a specific ratio. Your small intestine absorbs water most efficiently when sodium and glucose are present together in the right proportions. Oral rehydration solutions like Pedialyte are engineered for this, containing about 45 milliequivalents per liter of sodium, 20 of potassium, and 25 grams per liter of carbohydrate.
Chicken broth has zero carbohydrate and roughly five times more sodium than Pedialyte. That imbalance means your gut can’t use the same efficient absorption pathway. You’ll still absorb fluid from broth, just not as effectively as you would from a properly formulated rehydration solution. For mild diarrhea lasting a day or two, broth plus water and a normal diet is usually fine. For severe or prolonged diarrhea, especially with signs of dehydration like dizziness, dark urine, or dry mouth, an oral rehydration solution is the better choice.
Watch for High Sodium and Hidden Ingredients
The sodium content in commercial broths varies dramatically. Regular Swanson chicken broth contains about 860 mg per cup, low-sodium versions drop to around 140 mg, and unsalted versions go as low as 35 mg. If you’re sipping multiple cups throughout the day, regular broth can push your sodium intake quite high. For most people recovering from diarrhea, that extra sodium is actually helpful in the short term since you’re losing sodium with every loose stool. But if you have high blood pressure or are on a sodium-restricted diet, stick with low-sodium versions or dilute regular broth with water.
A subtler problem is what else is in the broth. Many commercial chicken broths contain onion and garlic, both of which are FODMAPs, a group of poorly digested sugars that can trigger or worsen diarrhea. Onion and garlic are among the most common FODMAP triggers, and Harvard Health notes that eliminating FODMAPs from the diet often resolves diarrhea within one to two weeks. If you have irritable bowel syndrome or notice that your diarrhea worsens after drinking broth, check the ingredient label. Look for broths that skip onion and garlic, or make your own with just chicken, salt, and tolerable vegetables like carrots or celery.
Broth for Children With Diarrhea
For kids, the stakes are higher because children dehydrate faster than adults. The CDC’s guidelines on managing acute gastroenteritis in children are clear: standard commercial oral rehydration solutions should be the first choice for replacing fluids, not household beverages like broth, juice, or soda. The concern is that homemade or improvised rehydration fluids often have the wrong concentrations of sugar and electrolytes, and serious errors in homemade solutions have been documented.
That said, broth isn’t off-limits for children. It can serve as a supplemental fluid alongside a proper rehydration solution and an age-appropriate diet. The CDC emphasizes that maintaining nutrient intake matters alongside fluid replacement, and a small cup of warm broth can provide both comfort and calories when a child refuses to eat. Just don’t use it as a substitute for Pedialyte or a similar product during active dehydration.
How to Use Broth During Recovery
The practical approach is to treat chicken broth as one tool among several. Sip it warm between meals to get sodium and fluids in, especially during the first 24 hours when solid food may not appeal to you. Pair it with an oral rehydration solution if your diarrhea is frequent or watery. As your symptoms improve, you can use broth as a base for simple soups with rice or noodles, which adds the carbohydrates your body needs for more efficient fluid absorption.
Avoid drinking large amounts of any fluid right before or after eating. Fluids encourage motility, meaning they speed up how quickly food moves through your digestive tract. Sipping broth slowly throughout the day is more effective than gulping a large bowl at once. If you’re making broth at home, simmer bones for at least four to six hours to extract more of the gut-supporting amino acids, and keep the seasoning simple to avoid irritating your already-sensitive digestive system.
