Hurray, at last Lorenzo reported to us his hunting experiences with fat, and
his animals seem to be really fatty. Not in the meat, but between organs.
This is of concern, Lorenzo, not because of doubting the importance of fat.
To the opposite. Only really high fat animals enable a hunting culture with
*predominating* meat (as you can read at
http://maelstrom.stjohns.edu/CGI/wa.exe?A2=ind0008&L=paleodiet&D=1&O=D&P=56
).
And such animals were found - no doubt - in northern (cool) areas and
enabled several waves of human expansion, animal based, from Cro Magnon to
Neanderthal to homo erectus (and the last prevailed).
You doubted that african animals would be "skinny".
I ask, why should they be fat, whats *their* advantage in a worm area?
Kangaroos (warm area animals) seem to be skinny. See
http://maelstrom.stjohns.edu/CGI/wa.exe?A2=ind0008&L=paleodiet&D=1&O=D&P=416
The main paleo-nutrition paradigm is adaption to food.
If evolution occured mainly in a warm climate or simply a climate
where animals weren't so fatty,
then meat was always a minor part of the diet.
Maybe someone, maybe you could go hunting in some warm grasslands or
savannahs and report how much fat is found in *such* areas.
You aren't so old, are you? ;-)
You describe how easy it is to hunt a caribou (in Canada).
Using a gun i assume.
Well, todays inuit can do it too.
How would a "naked, even with an excellent spear" do?

Todd, you computed the Saturated fat percentage.
What do you say to the difference in PUFA percentages?
(columns PUFA divided by total fat)

Pork and poultry seems in range, beef is far below.
The ratio of PUFA to SFA has beed suggested as an important
scale (PS ratio).
Udo Erasmus' work would suggest a PUFA to SFA+MUFA ratio as more important.
He gives matching studies, and a striking reasoning.

Me please too.
Norm, I'm starting to build a local database from USDA data
( I got from "wombn" ).
Which program are you using? Could I have access to it?
And what is RDI? 293 grams protein cannot be 63% of recommeded daily intake,
can it?
