Hi Emily, I realize that this may not be the avenue that you are looking for, but I can offer you my own definition of what is "true paleo" based on my interpretation of NeanderThin. When we go to the supermarket for "true paleo" foods, we buy only those foods which would not require the use of technology to make them edible. (I am sure you realize this.) While lemmings may have been consumed by our ancestors, the only lemmings that are available for purchase these days that I am aware of are the virtual kind (remember the video game? haha.) One cannot duplicate with exactness the diet of our very first ancestors. Even if we could, there is still some discrepancy as to what was actually consumed, by whom, when and where. What are your reasons for eating paleo? We are all coming from different situations here. My family eats paleo because of food allergues (grain, dairy, soy and more). Others here are bodybuilders, or trying to keep extra weight off, or are simply trying to maintain their health or recuperate from illness. You will have your reasons for going paleo in mind when you are choosing your food. If there are exceptions to be made, you will make them with based on your own individual circumstances. For example, we sometimes eat winter squashes (like pumpkin). These are not edible raw, but we are not allergic to them, nor are we trying to lose weight so we do eat them occasionally. (I only buy whole gourds and cook them myself. I try to stick with organic heirloom varieties.) Are they true paleo? IMO, no. But they are delicious! There are some here who do eat peas or green beans, though they are legumes and generally not considered paleo. Many here eat conventional beef, which is definitely not paleo. Grassfed meat is available (http://www.eatwild.com) and preferable to grain-fed, though it's meat does not compare exactly to wild meat it is a closer match. Also if you wanted to be absolutely paleo, you would eat only wild foods that are indigenous to your area. eg: If you live on the US east coast, you would not eat coconuts, pineaple, chicken, pork, ostrich, etc. To me, this is true paleo, and in my case is impossible. My "expertise" (I use the term loosely) lies in the kitchen, not in archaeology or palaeontology. I too am "just a mother with only a high school education". My cares lie herein. Our ancestral mother was also "just a mom" whose interest was in survival, not the nutritional composition of the grubs she dug up. Best, Stacie
