The study was carried out on 1466 subjects, whose ages ranged from 20 to 80 years of age, of whom 1181 were dentulous and 285 were complete dentures. We studied the frequency with which the 1466 cases partook of food. The results were as follows: 1) Ingested foods were classified into 10 groups along with the frequency with which they were ingested on a yearly seasonal basis. Food groups were classified as follows: vegetables, grain, sea food, beans, meat, seaweed, potatoes, fruits, etc. 2) The Ingested foods of the dentulous group were similar to those of the complete denture wearers. 3) In all age groups the foods most ingested were: steamed rice, wakame, tofu, bread, scallions, Japanese omelette, and tomatoes. 4) The younger subjects (20 to 39 years) statistically ate significantly lower amounts of steamed rice than did the older age groups. 5) The younger generation ate more meat, while the older groups ate more sea food.
