Resources are a treat.  Finding them can be a challenge in some parts of the
country, but book stores often have the titles listed with publishers and can
be located that way.
In reference to your questions:
Earl Mindell has written several books about nutritional content, you can find
them in
most book stores.  The nutritional almanac has been in publication for over 10
years, having gone into several publications and updates.  Both can be found
in most book stores, or your library could find them.  My books are in storage
right now or I would be more precise.

In peace
