This assumes that the organs all come from 100% grassfed sources - for example, I used to get a source of grainfed brains from pigs(cattle brains are forbidden in the UK for sale). The following fats are listed in descending order from greatest to least, and I;m measuring them in terms of what other trace micronutrients they have, other than just fats:-
Brains
Marrow
Tongue
Hide-Fat
Muscle-Meat Fat
Suet
-------
(Optional)
Eggs
Dairy
Is Hide-Fat the fat just under the fur and muscle-meat fat the fat in the muscles?
On Friday I got over 1kg lamb brains; I have only had 3 up to now - I like them, but as a treat because it would have been a treat in paleo times too!
Now I will have to throw most out because I could never eat that many and "normal" people would not be interested in me giving them brains

I notice that brains have a lot of cholesterol which is calming...
