During the aging process (especially very old cheddar) certain chemicals
are produced which could bother a person with a compromised immune
system. I think if you go to a search engine, you may be able to get
on the subject of aged cheddar and determine what the chemicals are
that develop to give aged cheese its sharp taste. These chemicals might
affect a sick person in a negative manner.
This single book has been more informative than any doctor I've spoken with. The opening chapters outline underlying causes for these various illnesses and go into great detail. This gave me the tools to better approach my doctors and explain what was going on to family members.
