In view of the inroads of “fowl” (chicken and turkey) medicine for health and physical attributes, it is known that long diets of medicated fowl can affect some humans (eg, cases of immunity to some medications). In the chicken soup study that resulted in the article “Chicken Soup Inhibits Neutrophil Chemotaxis In Vitro,” which was published in CHEST (October 2000),1 was any consideration given to the chickens used in the study? Were they free of medicine, steroids, and such in their feed? I’m certain some fowl would affect respiratory infections if loaded with antibiotics and the like.

I made the recipe with chemical-free chicken that had no special feed, and the soup was delicious! However, I wonder if any thought was given to this aspect in your study.

To the Editor:

Ms. Durfee raises an appropriate and insightful point. No special considerations regarding the chickens were made in our study except that they were old birds, as recommended by Grandma. We are unable, therefore, to answer the question regarding whether the chickens had received antibiotics or other medications. We suspect that it is likely that they did. Whether such agents contributed to the activity observed in the soup, obviously, cannot be determined from our studies. We did observe neutrophil inhibitory activity, however, in extracts of each of the individual vegetables. It seems reasonable, therefore, to suspect that the soup contains multiple activities, at least some of which are likely to have been derived from “natural” sources.
