| Research Abstract |
Okinawa prefecture holds the highest life expectancy in Japan, which has drawn attention both nationally and internationally. However, compared with the other prefecture, the dietary style of Okinawan people is more westernized mostly due to 27 years of being governed by the United State. Our research is about the dietary life of Okinawan residents according to their age group. We took measurements of both their blood properties and the micronutrient found in their specific regiment with the view to grasp the risk factor of geriatric deseases and prevent them. The result was as follows:

(4) In order to get the data of their daily life, we examined, 438 Okinawan female high school students and as the composition group, 278 female high school students in Nagasaki and Miyazaki prefectures. In the former group, we found such problems in their basic attitude toward food intake, eating between meals and not taking break fast, or their lack of consciousness about exercise or their physical shapes.
