A rather extraordinary study by some scientists in Sweden has revealed that the key to beating diabetes could lie in adopting a Palaeolithic diet similar to our hunter-gatherer ancestors. A diet consisting of fruit, nuts, vegetables and lean meat or fish appears to be much more beneficial than a traditional Mediterranean diet, the study revealed. 14 glucose intolerant heart patients were placed on the stone-age diet while another group was placed on the Mediterranean diet for 12 weeks. At the end of the study period the blood glucose levels in the first group had returned to normal while those on the Mediterranean diet had barely changed.
