Because I am allergic to tree nuts
Not allergic to coconut, a drupe, though.
But to answer your question, I think coconut product is more widely available. I have seen coconut oil, in both buttery and spray form. Coconut sugar. Coconut flour. Ever see all that in macadamia nut version? You get the gist.
Stumbled into Primal due to food allergies, and subsequent elimination of non-primal foods.
