Staffan Lindeberg is a professor in the department of medicine at the University of Lund in Sweden. He was interested in a Stone Age diet. In the early 1990s he travelled to Papua New Guinea to study the diet of the people on the island of Kitava as it was very close to the Stone Age diet. While there, he found that people did not suffer from heart attacks, diabetes (糖尿病), being overweight and many other diseases common in western countries.

As a result of his findings, he decided to test patients in Sweden to see how such a diet would affect them. Fourteen patients followed a Stone Age diet while another fifteen followed a Mediterranean diet, also healthy with lots of fruit and vegetables. All of the patients in the tests had high blood sugar levels, most suffered from diabetes and all had heart problems.

At the end of three months, the group following the Mediterranean diet had reduced their blood sugar levels by a small amount but those following the Stone Age diet had much lower levels of sugar in their blood. The patients in both groups also lost weight although the level of sugar in the blood and the patients' weight didn't seem to be related.

So, what is it about the Stone Age diet that can make us healthier? The diet contains some meat, fish, vegetables and nuts (坚果) but it doesn't contain any dairy products (乳制品) or grains, and there is no salt.

The next question is whether the Kitava people are healthier than us. After all, their life expectancy (预期寿命) is much lower. According to Professor Lindeberg, this is not as simple as we may think. Because of their poor health care, there is more chance of them dying at a young age. However, if people on Kitava manage to reach fifty, they are likely to live as long as people in more developed countries.
