Staple foods (as eaten thousands of years ago) would be primarily fruit, berries,
vegetables (including starchy roots as they are filling) and plenty nuts (proteins+good fats), meat would only be an occasional treat.
But the main point to stay healthy IMHO is to avoid everything processed, food should be in a as natural state as possible.
Not to stay off topic, and this will be my last comment on the subject, but the animal/plant ratio is debated among Paleo/Atkins eaters. I suspect that different human groups ate different proportions depending on the time of year and where they lived/evolved geographically. For example, fruits/berries and other seasonal produce were probably only eaten at the time of harvest in season, unless they sun-dried fruits/berries/veggies for later consumption. Studies of current hunter/gatherer groups worldwide appear to indicate high seafood protein consumption and/or small game (birds, rabbits, reptiles, insects, etc) in lieu of the less often "big kill" (deer, etc). For example, current Inuit ("eskimos") eat like their forebears did- very high protein/animal fats- seafood, seals, whales, etc- little plants, assuming traditional groups uncontaminated by modern processed and junk foods.
It's probably safe to assume that plants were a significant food source for many evolutionary ancestors, including starchy veggies and legumes. Moving forward, I may adjust my animal/plant ratio in favor of plants.
Luckily, chicken eggs are required to be hormone free in the US and are easy to get with Omega 3 from organic plant fed chickens for little cost premium at local supermarkets, an alternative to high cost grass fed organic beef as an animal protein source with omega3.
Yes, the most natural state and least processed food is of course most desirable, as we've all been told most of our lives and is basic common sense from an evolutionary, genetic ancestry viewpoint.
Nothing really to debate- just eat what those in the Blue Zones eat to minimize risk of chronic aliments and maximize lifespan-https://en.wikipedia.org/wiki/Blue_Zonehttp://www.ted.com/talks/dan_buettne...to_be_100.html
