Chicken soup has long been hailed as a comforting remedy for sickness, with generations from various cultures swearing by its healing properties especially in the west. But is there any scientific evidence to support this belief, or is it simply a placebo effect?
The origins of chicken soup as a therapeutic remedy can be traced back to ancient China, thousands of years ago. Remember the chicken essence commonly used as a gift for recovering patients? Its popularity spread across the world, and even army surgeons like Pedanius Dioscorides, who served under the Roman emperor Nero in 60 A.D., recognized its potential benefits. But what exactly makes chicken soup so special?
One key element is the umami taste, which is often described as having a “meaty” flavor. This taste sensation is attributed to the amino acid glutamate, found in foods like meat, poultry, cheese, mushrooms, miso, and soy sauce. Studies have shown that the umami taste can stimulate appetite and improve nutrient digestion.
When we’re sick, our bodies often experience an inflammatory response that can decrease our appetite. This lack of nutrition can hinder our immune health and recovery. However, the umami taste in chicken soup has been found to increase appetite. Participants in a study reported feeling hungrier after consuming soup with added umami flavour.
Furthermore, the umami taste can prime our digestive tracts to absorb protein more easily. This can alleviate gastrointestinal symptoms that often accompany illness, such as abdominal pain, nausea, vomiting, and diarrhoea. While we may not associate these symptoms with upper respiratory infections, research in children has shown a link between the flu virus and gastrointestinal distress.
In addition to its impact on appetite and digestion, chicken soup may also help reduce inflammation and alleviate common cold and flu symptoms. Inflammation is a natural response to illness or injury, but it can lead to nasal congestion, coughing, and thickened mucus. Interestingly, research suggests that chicken soup can lower the number of white blood cells that migrate to inflamed tissues, thereby reducing inflammation. This effect is achieved by inhibiting the ability of certain white blood cells, called neutrophils, to travel to the inflamed area.
To fully appreciate the soothing and healing effects of chicken soup, it’s important to consider its ingredients. Not all chicken soups are created equal, and some store-bought versions may lack the nutritious properties found in homemade recipes. Canned soups, especially those that are heavily processed and devoid of vegetables, may not provide the same benefits.
Homemade chicken soup, on the other hand, contains key nutrients that can aid in recovery. Chicken offers a complete source of protein to combat infection, while vegetables supply a range of vitamins, minerals, and antioxidants. Noodles, if included, provide easily digestible carbohydrates for energy and recovery.
The warmth of chicken soup itself can also contribute to its healing properties. Drinking the liquid and inhaling the steam can increase the temperature of nasal and respiratory passages, loosening thick mucus. Studies have shown that chicken soup is more effective than hot water alone in this regard. Additionally, certain herbs and spices commonly used in chicken soup, such as pepper and garlic, can further help in loosening mucus.
While chicken soup may not be a cure-all for colds and flu, the latest scientific research supports its role in healing and recovery. The umami taste stimulates appetite and improves nutrient digestion, while the soup’s ingredients provide essential nutrients and help reduce inflammation. When choosing chicken soup, opt for homemade varieties packed with vegetables and nutritious ingredients. So, the next time you or a loved one is feeling under the weather, consider a comforting bowl of homemade chicken soup – it seems Grandma was onto something after all.
