There are signs that a gradual awareness of the importance of nutrition is dawning within the medical profession, an awareness forced upon it by persevering people like Nathan Pritikin. In 1982 a comprehensive report called Diet, Nutrition and Cancer was issued by the US National Research Council. The report was prepared by a committee of people from the National Academy of Science, the National Academy of Engineering and the Institute of Medicine. Although the report revealed a lamentable lack of comprehension of the subject, it did in fact demonstrate that nutrition was a significant factor in the origins of cancer. Note that the report emanated from outside the medical profession, as has a recently released book in Australia called Diet, Health and Disease in Australia, written by a number of doctors and produced by the Australian Academy of Science.

The research for both of these books obviously did not extend far outside conventional circles. In relation to cancer the lack of knowledge was lamentable, as was the lack of knowledge of diabetes and other disease problems described in the Australian book.

Inadequate as these books may be, it is gratifying that they have appeared at all; it shows that some doctors are at last breaking free of their mental shackles.

In his book Man, the Unknown, the great physician and philosopher Alexis Carrel said: "Unless the doctors of today become the dieticians of tomorrow then the dieticians of today will become the doctors of tomorrow." Maybe this is starting to happen. Evolution is a slow process, and bearing in mind that it took hundreds of years for people to accept that the world was round, I suppose we should not complain too much.
