Thank you for the answer relating to chick peas.
Hmm... on the lentil issue, I've now heard a range of opinions from 40-30-30 diet experts saying, "don't count the protein in it", to "only count a portion of the proteins in it" to "count full proteins in it"... this is all very confusing! Yes, the 25% thing is just my mind playing up again, but I do remember reading something to the effect of only counting partial protein calories from them. For example: (quote from http://www.zonediet.com/forums/aft/47772,
the last post):
"Dr. Sears explains in his books that he doesn't count the protein in most veggie foods, some exceptions being soy and gluten "meats", because some of the protein in plants is trapped inside intricate structures of insoluble fiber. Since unsoluble fiber doesn't break down in the human digestive tract, the trapped protein never becomes available for absortion. This makes most plants an unreliable source of protein for humans."
Is this true?
