Um, not everyone is trying to get the most calories for our buck. Some of us are trying to get the most nutrition. Different things.
A primal database where one could search by macros, calories, etc. would be helpful. I'm finding some of the calorie counting programs don't have the more exotic things like bison liver or elk meat in their databases. I have to run all over the net chasing down the info and then enter it manually. If we could invent the Primal version of SparkPeople, that would be cool.
