Chicken soup has been shown to help clear nasal passages and reduce inflammation. While hot fluids generally help clear nasal passages, chicken soup has been shown to be better when compared to other hot liquids (1).
It is a great source of vitamins, minerals, calories, and protein, all of which are nutrients you need when you’re sick (2). It also helps you to stay hydrated and is an excellent source of electrolytes, two critical factors when dealing with a cold or flu (3).
One reason for chicken soups beneficial effect is that chicken contains an amino acid called cysteine which is anti-vital, anti-inflammatory, and helps to break apart mucus (4, 5). For a vegetarian source of cysteine, try adding lentils to your soup.
Aside from the chicken itself, chicken soup typically contains a number of ingredients that can help to ease cold symptoms. Onions contain a compound called quercetin which is both antiviral and antibiotic (6). Garlic and ginger have also been shown to have antiviral properties (7, 8).
On top of all the actual evidence to show that chicken soup helps fight a cold, it’s also easy to eat and soothing when you’re not feeling well.
