best:

You asked about hearth health.  The book for that would be the one with
"health healthy" in its name by another couple of good doctors with much
expertese in the low carb realm:

Available, I'm sure, at a library near you.

If you go to the Amazon site, they will have other recommendations as
well.

The there is a google search for Paleo recipes (a little counter
intuitive, recipes?)

or the google search for Paleo foods
<http://www.google.com/search?client=safari&rls=en&q=paleo+diet+food+list
&ie=UTF-8&oe=UTF-8>

You'll probably want to see "Sugar: The Bitter Truth" as well

IIRC, the lecturer, Robert H. Lustig, MD, UCSF Professor of Pediatrics
in the Division of Endocrinology, says, flat out, that modern medical

Good Luck,
