We all know the grandmotherly wisdom of serving chicken soup to someone with a cold, but does this particular meal really have the same effect as the medicine? Could the chicken soup save people a trip to the local hospital?
You won't find studies in humans that prove chicken soup can fight a cold, but there's enough evidence to make it worth trying. One study published in the medical journal Chest suggested that chicken soup?might have anti-inflammatory(消炎的) effects, which could possibly cure symptoms of upper respiratory tract infections. Researchers studied the movement of neutrophils -- a type of white blood cell -- when combined with soup. They found that the movement of neutrophils was reduced in the presence of soup, suggesting a possible anti-inflammatory effect that could at least reduce cold symptoms. 
"There are substances in chicken soup that could affect cells in the body, that could possibly have medicinal effects, but whether they are good or bad for you, we didn't test," said study author Dr. Stephen Rennard, Larson professor of medicine at the University of Nebraska Medical Center in Omaha. Because the study was done in a laboratory and not in humans, Rennard adds that it remains to be seen whether one would even absorb the substances that appeared to have beneficial effects in the lab. The researchers did not actually separate specific substances in soup that might be beneficial, "nor did we show what it would do in a living person, let alone a living person with a cold," he added.
"Chicken soup might be useful ... but lots more research is required," Rennard said. "There is some possibility that there is a medicinal basis to it ... but 'some', 'suggests' and 'possible' are the key words."
