Why aren't the health benefits of coffee advertised more?

I was talking yesterday to one of the great PR people in DC, Janet Fallon, about the health benefits of coffee,

"Coffee a top source of healthy antioxidants"

"Researchers have found strong evidence that coffee reduces the risk of several serious ailments, including diabetes, heart disease and cirrhosis of the liver."

"Drinking coffee protects against an eyelid spasm that can lead to blindness"

"Prevents gout"

Her question was one that I was disappointed that I hadn't already asked myself: If so, why don't the coffee companies advertise this? The only answer that I have to her question is that if they raise health benefits, they might also have to get into issues such as this:

"U.S. scientists say they`ve determined a single cup of coffee might cause a heart attack in some people within an hour of drinking it."

Coffee companies could face liability if someone had a heart attack and they started drinking coffee for the health benefits.

UPDATE: As Janet correctly points out to me, these concerns haven't stopped red wine makers from advertising the benefits from drinking their wine.
