In the last section, I explained why eating old-school, waaaay old-school makes sense: our bodies evolved for it, and function much better when we do. Paleothic eaters, like more modern hunter/gatherers, were lean, fit, and free of most of the chronic diseases that plague society. So what, exactly, did they eat?

Well, lots of different things. Obviously Paleolithic hunter/gatherers in the heart of Africa ate wildly differently from those living in the Swiss Alps or along the coast of Alaska. Fortunately for you, with the miracles of the modern food system, you likely have access to the vast majority of what any of them ate. Unfortunately for you, you also have access to all kinds of other items that almost certainly didn’t show up at Paleo dinnertime. What makes the cut? First, two rules of thumb:

• If you were stuck out in nature with nothing but some sharp sticks and rocks, would the food still be available to you?
• Could you eat it raw, unaltered and unprocessed, and still extract the nutrients from it without becoming sick?

If you can answer yes to both, the food fits. That doesn’t mean you have to actually procure the food yourself using rocks and sticks. Similarly, that doesn
