Says here that if you're making chicken soup to take care of a cold that you or a loved one is suffering from, go heavy on the celery.

In the new study, Kikue Kubota and colleagues note that cooks have long recognized celery's "remarkable" ability to enchance the complex flavors of soups and broths. Almost magically, celery takes on a sweet-spicy flavor after boiling, helping to give food a thick, full-bodied, satisfying taste. Until now, however, scientists have been unable to track down the roots of celery's effects.

What the heck.  Toss in some broccoli, too.

They gave broccoli extract to lab rats for one month and measured its effects on the rats' heart muscle. Compared to a control group that ate a regular diet, the broccoli-fed animals had improved heart function and less heart muscle damage when deprived of oxygen. Broccoli's heart-healthy effects are likely due to its high concentrations of certain substances that seem to boost levels of a heart-protective protein called thioredoxin, the researchers note.

It's good for ya.  Can't hurt, anyways.
