The recommendations of the Okinwa Program repeat information that has been available for a long time. The benefits of low-fat, low-calorie diets, exercise, and reducing stress are well known. This is just one more book for the already overloaded shelf of self-help books. It might be interesting to compare life-expectancy of Okinawans BEFORE World War II with this data, as it necessarily excludes members of the same generation who died of malnutrition, illness, accident, or war-time incidents before that time.
