Thanks for moving this, Tyler. The fact that the original question concerned a cooked foods version of zero carb diet on a raw paleo forum, begged for it to reside in hot topics.
Nicola, I quite agree that bone stock soups are very valuable. As many of you know, I began eating RVAF about 1.5 years ago. I have never quite given cooked foods the boot completely (mainly due to family life) - I eat 60-90% raw daily, increasingly RAF. I eat only paleo foods plus wine on occasion. The majority of the cooked foods I eat are in the form of soup stocks which have been simmered in water and a bit of acid like lemon juice or coconut vinegar for over 24 hours. Beef and lamb are the main bone stocks I make, although if I can get fish bones and heads in season, that is also great. Poultry I do to a lesser extent. I make them nearly daily. I eat them every other day, especially in winter.
There are a ton of minerals and connective tissues available with stock preparation. It is, imho, a great use for marrow bones once the marrow has been eaten raw. Why not? I realize some of you have to eat all raw for health, or choose to be all raw for other reasons. But I would have to say that bone broths are by far the most benign (and perhaps) health-giving cooked foods around. In addition to what Nicola said, this article spells out why these foods might be a good choice.

Also, I try to keep to a middle path in my life. After veganism, I found that any total all or nothing approach is probably not a good thing for me personally. So while I totally love RAF, and I will never go back to dairy, grains or the majority of my food cooked again, I feel this one food does make sense. As a highly-trained martial artist in my 40s, I think my joints thank me for adding this food in my diet. It is impossible to eat bones raw, unless you are talking anchovies, and I do eat those whole. Gnawing on joint bones of big land animals is something my dog does better. So that is my reasoning, and here endeth the sermon.
