Why do we "feed a fever and starve a cold"?

I think it’s the other way around. I think the wivestale’s logic is don’t give the fever any more energy (starve a fever) and vice versa (feed a cold.)
No clue if there is any sound logic in it.

What you talkin’ ‘bout?? I feed EVERYTHING!

Poor snupfy Penguin! Feed it, feed it all!

haha, starve a fever, feed a cold.

“We now know that the cold and flu are caused by viruses,” says Curt Gingrich, MD, associate program director of the Riverside Methodist Hospital Family Medicine Resident Program in Columbus, Ohio. “Starving a fever is not helpful. In addition to making sure you are drinking plenty of fluids during an illness, be sure to also get plenty of rest,” says Dr. Gingrich. “If you have a high fever or a fever lasting more than two to three days, you will need even more fluids to keep from getting dehydrated.”

I thought it was “starve a fever, sleep a concussion”. :P
