It has been suggested that several factors such as geographical economical and occupational conditions as well as food distribution system are largely influencing on the structure of food intake. However very few investigators have conducted the survey on the relation between food distribution and regional food intake. This is mainly because the method of food distribution survey has not yet been specified definitely. The authors were having story interest in this relationship, especially in the food distribution system of the small isolated island where the food consumption might be biased by the limitation of food transportaiton. The authors had a chance to do a food distribution and dietary survey at Yonaguni Island. Okinawa in Sentember 1973 and 1974. Three hamlets (Sonai, Kubura and Higawa) were surveyed. The authors checked up all the food items sold at each food shop situated within each hamlets. And we obtained several interesting results as followings. At Kubura hamlet where fishery was the most prevailing occupation, the number of fishery food items were far exceeding than the other 2 hamlets. On the contrary, the food distribution of Higawa was the worst among the 3 hamlets where agriculture was the prevailing industry. There were only 2 food shops located in Higawa and moreover, the households of Higawa could not buy meats because these items were not distributed there. At Sonai where main official facilities were located and the number of food shops were far exceeding than the other 2 hamlets, the number of total food items and animal food items were exceeding than Kubura and Higawa. Thus the location of food shop as well as the difference of the prevailing industries of each hamlet were considered to largely influence on the dietary intake of the hamlets. Milk was not consumed in any households of Yonaguni Island because milk was not distributed within the island nor transported from outside of the island.

東京およびその周辺の都市に居住する7世帯について, 1981年11～12月の30日間について消費された食品の種類; 朝, 昼, 夕別の喫食者の内訳を調査した。
1) 累積使用食品種類数はすべての世帯において約20日を経過するとその増加割合が小さくなり近似飽和状態に達した。
2) 累積使用食品種類数, 毎日の使用食品種類数, 毎日の食品使用の個別性指標値には世帯間で差があり, 2人世帯はすべて小さな値を示した。
3) この世帯間格差の原因の一つに家庭内での食事割合の差があげられ, 世帯構成員の性, 年齢, 就業・就学状態などがそれと関連していた。
4) 調理担当者が就業している4世帯のうち1世帯は2人世帯で外食の頻度が高かったが, 他の3世帯では週の前半の個別性指標値が後半のそれより高値であった。

It has recently become important to study the dietary pattern since many of the chronic diseases would be related with food intakes and its pattern. Generally speaking, there are two ways to find the relationship between foods and physiological status, i. e. longituditional case studies and community surveys. The authors studied food consumption and food items consumption of more than 3000 households. With these original data, the authors tried to analyze food intake patterns which might be existing in each local community. Moreover, some of community-food-intake-patterns are similar when the ecological situations of the local communities are alike. The similarity of food consumption is not only fairly useful in practices of health activities, especially nutritional education in the community, but also in etiological studies of chronic diseases.
In this study, together with following serial report, we propose a new index which will explain the situation of food consumption of the community with the average food consumption of the nation. Community food pattern is composed of 6 food group index. (x, y). Index X is computed by food amount consumption of the community, while index Y is computed by consumption of food item numbers. From the pattern similarity of the community models, one can have the information of the dietary pattern of the communities.
However this model is not a mathematical model but an analogus model, so that the similarity analysis should be carried out with more detailed method of “similarity analysis”.
We intend to apply these indices to other materials furthermore.

福岡市にある栄養・食物関連の女子大生30人に対し, 連続5日間, 450食 (1日1人3食として) における摂取食品品目について調査し, その摂取食品品目が食事回数の増加とともにどのように増加していくかを追跡した。
1) 摂取品目数は全体で503品目であった。100品目を摂取するのに20食, 200品目で70食を要した。
2) 1食平均11.6品目, 1日で29.1品目が摂取されていた。
3) 多数の摂取食品品目があることは, 女子大生の食生活の豊かさを示しているが, それは若い彼女らの好奇心によるであろう。
4) 摂取された食品はすべてその摂取頻度とともに表で示した。米は食事2回中1回の割合で摂取されていた。次いで塩, しょうゆ, 砂糖, 卵, にんじん, ミルク等が高頻度で摂取されていた。
5) 摂取食品のABC分析によると, 26品目で全体の50%, 94品目で80%, 173品目で90%の摂取頻度がみられた。
6) 理論的に摂取される最大食品品目数は626品目であった。
7) 飽和増加曲線を用いる摂取食品数の解析は, すべての食品を網羅することができ, “何を食べているか”という食性の研究に適している。この種の解析に注意すべき食品名の統一が必要であることを考察した。
