To Dr Guy Wrench, it is more interesting to know why we are not as healthy as we should be, than it is to ask why we are as diseased as we are. If we can just be healthy, disease is not an issue.
Not surprisingly, he had difficulty in finding people in whom he could study health as both a natural and dominant characteristic, but finally, he found the group of people his study needed - in the tribe of the Hunza, in Northern Pakistan.
The very place itself is fascinating, lying hidden high up in one of the tremendous valleys among the great mountains separating Pakistan from China and Russia.
The Hunza were people were renowned for their extraordinary physique and health, which Dr Wrench found by the fact that their food was not made 'sophisticated', by the artificial processes applied by modern processed food. How these processes affect our food is dealt with in great detail in this book.
The answer that Dr Wrench uncovered in his researches goes deeper than just the food, though. The answer lies in what was special about the Hunza's water supply.
