If you add some seafood I would say there shouldn't be any shortage of any nutrient...
I should know this by now but we can't survive off of whole animals alone? Even after growing up on many types of plant food it seems like it would be foreign to choose to eat plants in the wild(when seafood not available)... of course with fruits being the exceptions, but everyone says modern fruits were non existent in those days.
By law, you should be able to get everything but the brain.
Where did you learn this? I'm having trouble finding the federal government guidelines/rules for meat inspection. But this page mentions BSE prevention
http://www.azda.gov/Main/administrative_rules__laws.htm"they prevent cattle that cannot walk or rise from being slaughtered for use as human food. Two, they prevent specified risk materials from cattle over 30 months old, including the brain, skull, eyes, trigeminal ganglia, spinal cord, certain parts of the vertebral column, and dorsal root ganglia, and the tonsils and distal ileum from all cattle from being used in the human food supply. "
I'm pretty sure I/you can still get brains from cattle under 30 months old. Neither of the inspectors I've talked to so far have said I can't get brain.
Seems like it would be on this page/site
http://www.fsis.usda.gov/regulations_&_policies/Federal_Meat_Inspection_Act/index.asp but I can't find anywhere that it talks about specific parts of the animal. So I called the same inspector again and he told me only certain things like the penis and certain glands are not allowed to be sold for food, and he also confirmed the 30month brain thing. He said the gal bladder & lungs are not allowed but the spleen is allowed. He said a lot of it is up the establishment on whether or not they wanna give you something, and you can get somethings if you tell em it's not for food(human consumption)...
I told him I wanted to read this somewhere and he said it's in $400 books that might not even be available to the public, but that I might be able to find it on the usda fsis site(linked above) or somewhere else, and to search for 9cfr and the parts about this stuff might be in the 300's.
I did a quick google search for 9cfr and there are a few sites like this
http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?sid=900ea0ccb72010a4fb5a401f3d42f82c&c=ecfr&tpl=/ecfrbrowse/Title09/9cfrv2_02.tpl that seem to have everything. I don't have the time to go through it all right now, but I'll try to find exactly where it talks about the stuff we can or can't have as soon as I can.
I'm also curious to know exactly what organs/parts of the animal are worth trying to get. Like what their nutritional/health benefits are. Anyone know if there's already a thread about that(not sure what keywords to use to find that)?
