Chicken broth is good for hydration during illness, easing cold symptoms, supporting digestion, and adding nutrients to your diet without many calories. A standard cup contains only about 39 calories while delivering 5 grams of protein, 210 milligrams of potassium, and a meaningful dose of sodium that helps your body retain fluids. It’s one of those rare foods that works as both a recovery tool and a cooking staple.
Cold and Flu Symptom Relief
The old advice about eating chicken soup when you’re sick has real science behind it. A study published in the journal CHEST tested a traditional chicken soup recipe and found it significantly inhibited the movement of white blood cells called neutrophils, which are part of the inflammatory response that causes congestion, sore throat, and that general miserable feeling during a cold. The effect was concentration-dependent, meaning stronger soup produced a stronger anti-inflammatory response.
This matters because most cold symptoms aren’t caused directly by the virus itself. They’re caused by your immune system’s inflammatory reaction. By dialing down that reaction slightly, chicken broth can reduce the severity of congestion and upper respiratory discomfort. The warm liquid also helps loosen mucus in the nasal passages and keeps your airways moist, which makes breathing easier when you’re stuffed up.
Rehydration After Illness or Exercise
When you’re recovering from a stomach bug, plain water can be hard to keep down. Warm broth tends to go down easier because it encourages slow, steady sipping rather than large gulps that can trigger nausea. That alone makes it a practical choice for rehydration.
But broth also has a chemical advantage over plain water. It naturally contains electrolytes, particularly sodium (about 747 milligrams per cup in a standard broth), along with smaller amounts of potassium and phosphorus. Sodium is the key electrolyte for fluid absorption. Your intestines actually pull water into the bloodstream more efficiently when sodium is present, which is the same principle behind oral rehydration solutions. If you’ve been sweating heavily, vomiting, or dealing with diarrhea, broth replaces both the fluid and the minerals you’ve lost.
Digestive and Gut Support
When collagen from chicken bones breaks down during cooking, it releases amino acids that play a role in maintaining the intestinal lining. One of the most important is glutamine, which serves as a primary fuel source for the cells that line your gut. These cells turn over rapidly and need a constant supply of building blocks to stay intact. Some research suggests glutamine supplementation helps maintain intestinal barrier function, particularly during periods of physical stress or illness when the gut lining is under strain.
Longer-simmered broths (often called bone broth) tend to contain more of these compounds. A chicken broth simmered for several hours will have measurable amounts of glycine (about 4 milligrams per gram of broth) and proline (about 2.4 milligrams per gram), both of which support connective tissue throughout the body, including the digestive tract. While broth alone won’t heal a damaged gut, it provides raw materials your body can use for routine maintenance and repair.
Appetite Control and Weight Management
One of the most practical uses for chicken broth is as a tool for eating less without feeling deprived. Research published in the journal Appetite found that people who ate a broth-based soup before a meal reduced their total calorie intake at that meal by 20%, or roughly 134 calories. The type of soup didn’t matter much. Brothy, chunky, and pureed versions all produced similar results.
A cup of chicken broth on its own contains only 39 calories, so even accounting for the preload, you come out well ahead. The warm liquid takes up space in your stomach and signals fullness before the main course arrives. If you’re trying to manage your weight, having a small bowl of broth 10 to 15 minutes before lunch or dinner is a simple strategy that requires almost no willpower.
Mineral Content and How to Boost It
Chicken broth provides potassium, phosphorus, and trace minerals, but the calcium and magnesium content of a basic broth is often lower than people expect. This is where cooking technique makes a significant difference. Research in Food & Nutrition Research found that lowering the pH of the broth (making it more acidic) by adding vinegar dramatically increased mineral extraction from the bones. Dropping the pH from about 8.4 to 5.3 increased calcium extraction by a factor of 17 and magnesium by a factor of 15.
In practical terms, this means adding a tablespoon or two of apple cider vinegar or another acid to your pot before simmering will pull substantially more minerals out of the bones. The acid dissolves the mineral matrix of the bone over time, transferring those nutrients into the liquid. Without acid, much of the calcium stays locked in the bones and gets thrown away. If you’re making broth partly for its mineral content, this one step is the most important thing you can do.
Joint and Connective Tissue Support
Chicken bones and cartilage are rich in type II collagen, a protein that’s specifically concentrated in joint tissue. This distinguishes chicken-based broth from pork or beef-based versions, which tend to contain more type I and type III collagen (the types found in skin and tendons). Type II collagen is the main structural protein in cartilage, and consuming it provides the specific amino acid building blocks your body uses to maintain and repair joint tissue.
Clinical research has explored hydrolyzed chicken collagen supplements derived from chicken cartilage for joint discomfort, with the hypothesis that these collagen fragments accumulate in cartilage and stimulate the cells responsible for cartilage regeneration. While a bowl of broth delivers lower concentrations than a supplement, regularly consuming chicken broth made with cartilage-rich parts like the sternum, feet, or neck provides a food-based source of these same compounds.
Choosing Between Regular and Low-Sodium Broth
The sodium content of commercial chicken broth varies widely, and the labels can be confusing. A product labeled “low sodium” must contain 140 milligrams or less per serving. “Reduced sodium” or “lower sodium” only means it has at least 25% less sodium than the brand’s regular version, which could still be quite a lot. A standard cup of regular chicken broth contains around 747 milligrams of sodium, roughly a third of the daily recommended limit.
If you’re using broth for rehydration during illness, that sodium is actually helpful. But if you’re cooking with broth daily, especially in recipes that call for reducing the liquid (which concentrates the salt), the sodium can add up fast. For everyday cooking, reduced-sodium versions give you more control. For sick days and post-workout recovery, regular broth’s higher sodium content is a feature, not a flaw.
Homemade vs. Store-Bought
Homemade chicken broth simmered for several hours with bones, cartilage, and a splash of vinegar will contain more collagen, more amino acids, and more minerals than most commercial options. Store-bought broth is typically cooked for shorter periods and often relies on flavor enhancers to compensate. That said, commercial broth still provides hydration, electrolytes, and the mild anti-inflammatory benefits that make it useful during illness.
If you’re making broth at home, include joint-heavy parts like wings, feet, or a whole carcass. Simmer for at least four hours, and add an acid like vinegar at the start. You’ll know the broth is collagen-rich if it gels when refrigerated. That gel is dissolved collagen that has set, and it melts right back into liquid when reheated.
