RosieNew research at Lund University in Sweden can now show what Stone Age people actually ate in southern Scandinavia 10,000 years ago. The importance of fish in the diet has proven to be greater than expected. So, if you want to follow a Paleo diet -- you should quite simply eat a lot of fish.
"At the Norje Sunnansund settlement, outside Sölvesborg in Sweden, you can see that just over half of the protein intake has come from fish, ten per cent from seals, and around 37 per cent from land mammals, such as wild boar and red deer, and scarcely three per cent from plants such as mushrooms, berries and nuts," says Adam Boethius. "On the island of Gotland, which did not have any land mammals apart from rabbits, the percentage of fish in total protein consumption was even higher at just under 60 per cent. Here, seals have replaced the land mammals and account for almost 40 per cent of the protein intake, whereas rabbits and vegetables account for a negligible proportion," he continues.
