Wizard diseases and food...

We had a great discussion/debate a while ago about whether wizards 
are able to create their own food and such.  I seem to recall that we 
had collectively come to the conclusion that they couldn't, and if 
they did that the food would not stay but disappear after a certain 
length of time.

Now I wanted to ask- Did we ever decide if the food which wizards eat 
is provided by muggle suppliers or wizarding ones?  If it is provided 
by muggle suppliers then what happens to wizards that eat foods that 
could possibly expose them to Mad Cow Disease or other such things. 
What do they do if food is under cooked and they are exposed to 
salmonella (sp?) etc. 

Are they able to heal such diseases instantly? What about Cancer? 
HIV/AIDS? Have they been able to eliminate them through magic? Are 
there diseases and sicknesses that are unique to magic people?

Hmmmm, anybody want to jump in?
