沖繩県与那国島における食生活研究 (第1報)

抄録

Not few investigators have story interest on the relation between food intake and mortality. From the viewpoint of Dr. Kondo, we have also been motivated to survey Yonaguni Island of the Ryukyu Islands.
Dr. Kondo suggested that food consumption in this island would be characteristic and biased to the large intake of fish and meat.
But nobody can exactly describe the status of food in Yonaguni Island because no dietary survey on its inhabitants has been conducted.
We had a happy chance to do make a dietary survey there in October 1973, in jointwork of the Yaeyama Health Center.
Subjects; The subjects of this survey were fifty eight families selected at random from three hamlets (Sonai, Kubra and Hikawa)
Results; The results are shown below.
1. The intake of calories, protein, fat and vitamin C was estimated to be higher than the average of the Japanese National Nutrition Survey of 1971.
On the other hand calcium and vitamin B₂ was estimated as fairly lower than national levels.
2. In comparison with those surveys, the amount of several food items; fish, meat, green and yellow vegetables in Yonaguni are estimated to be higher than the National Level and Okinawa Island.
3. Food intake patterns differ among the three hamlets, which compose the community of an isolated island.
4. On the other hand, there is little difference in food preparation among them.
5. From above it may be said that the dietary intake of the hamlets is in unity, whereas food preparation is definite as the whole island.
