JOURNAL FREE ACCESSIn order to ascertain the basic food consumption patterns of Japanese, the food intake of Japanese immigrants in Brazil were examined in regard to the differences in age, years after immigration, and rice or bread intake. The results obtained were discussed as compared with those of Japanese in Japan. The principal results are as follows.
1) There was a difference in food intake between the younger and older generation that indicated adaptation to Brazilian food by the younger generation and persistence to Japanese food of the older generation. But the difference was not so remarkable as was found between Brazilians and Japanese Brazilians.
2) In the changes of food intake proportional to the years after immigration, many variety of changes was observed. Namely, intake of some Japanese food increased after a period of decrease, while with others there was a continued dwindling. And with some Brazilian food there was a brief period of increased intake just after immigration with subsequent decrease, while others showed smooth progressive increase in consumption.
3) As to the food intake in regard to rice, it was found that those who ate more rice took more of both Japanese and Brazilian food and that the amount of intake of rice had no correlation with the intake of bread and noodles, nor had it any correlation with the age or the years after immigration.
4) The amout of intake of bread showed no correlation with those of rice or noodles either. But the group that took more bread showed the Brazilian dietary pattern and the group that took less bread showed the Japanese dietary pattern.
As mentioned above, the dietary life of Japanese immigrants forms the dual structure by succeeding to the Japanese style and at the same time adapting to the Brazilian one. In this case rice is found to have connections with various foods and to play a role as a basic food of their dietary life. Thus, the dietary life based on rice is considered to be exactly the basic food consumption pattern of Japanese.View full abstractDownload PDF (12405K) -
—a Projection from Nutritional Investigations of Japanese Immigrants in Brazil—Part 2. From the Side of the Structural Analysis of Food Consumption PatternsSatoshi Okimasu, Masayuki Akabane, Noriko Kishida, Mitsuru Kimira1981 Volume 39 Issue 1 Pages 25-35

JOURNAL FREE ACCESSIn order to ascertain the basic food consumption patterns of Japanese, the food intake of Japanese immigrants in Brazil were analyzed through the multivariate analysis method, and the results were examined as compared with those of Japanese in Japan (Nakai-cho in Kanagawa Prefecture). The principal results are as follows.
1) As for the correlation matrix among the intakes of each food group, in Japanese colonies Miso, fermented soy bean paste, and Japanese pickles pickeled vegetables, to rice and, sugar and green and yellow vegetables to bread showed a significant positive correlation, while in Nakai-cho no correlation was noted among rice, Miso and Japanese pickles, and fat and oil showed a positive correlation to bread. As for the relationship among rice, bread and noodles, a negative correlation was noted in Nakai-cho, while the trend toward a positive correlation was in evidence in the colonies.
2) As for the factor analysis on the correlation matrix, in the first factor Japanese pickles, fish and shellfish, rice, noodles, meat, Miso and soysauce showed comparatively larger factor load, and in the second factor fat and oil, meat, sugar, eggs, fruits, potatoes and Japanese pickles showed larger factor load. Here the first factor showed the Japanese dietary life and the second factor showed the Brazilian dietary life, and it was judged from these facts that this suggested the dual structure in the dietary life of Japanese immigrants. In case of Nakai-cho, the first factor was considered to show subsidiary foods and staple foods and the second factor the rice, bread and noodles pattern.
3) The results of the cluster analysis of the similarity matrix among Japanese colonies investigated showed that the dietary life of immigrants was divided roughly into two clusters. But it had no relation with geographical localities and that such local characteristics as seen in Japan were not noted.
From the above-mentioned results etc., it is concluded that the dietary life based on rice and soysauce is considered to be exactly the basic food consumption pattern of Japanese.View full abstractDownload PDF (11965K) -

JOURNAL FREE ACCESSTo estimate the nutritive value of antarctic krill protein on human subjects, the digestibility and nitrogen balance index of krill protein in 5 male young adults were compared with those of egg protein.
The subjects received low protein diets containing 0.3g/kg/day and 0.5g/kg/day of protein of precooked, freeze-dried powdered krill and a whole egg for 4 days, respectively.
From the results of the present experiments, the digestibility of krill protein was observed to be similar to that of egg protein and the nitrogen balance index of krill protein was 0.546, whereas that of egg protein was 0.612.View full abstractDownload PDF (9384K) -

JOURNAL FREE ACCESSThe purpose of the present study was to determine the effects of cornstarch replacement with sucrose in a diet containing 1% cholesterol and 0.25% sodium cholate on the cholesterol metabolism in rats with various dietary conditions.
The kinds of carbohydrates produced no difference in growth rates, but sucrose diet resulted in a higher level of serum and liver cholesterol than did starch. Dry weight and cholesterol contents of feces excreted by animal for 4 or 8 experimental days were decreased by sucrose diets. Interactions between the dietary carbohydrates and fats were observed in the fecal output of cholesterol; the animals fed on the sucrose diet with soybean oil excreted more cholesterol in feces than ones fed the lard-sucrose diet. Conversely, in the starch diet, the lard diet stimulated more fecal excretion of cholesterol than the soybean one.
In the different kind of dietary fats, a marked elevation of serum cholesterol level was caused in the animals placed on the lard diets. Soybean oil stimulated the increased cholesterol content of large intestine and more fecal excretion of cholesterol.
The replacement of dietary carbohydrate with konjac flour remarkably depressed the rise in serum and liver cholesterol levels caused by cholesterol and cholate intake. The animals fed konjac flour accumulated more cholesterol in the contents of large intestine, which should be excreted to feces. Concomitant feeding of konjac flour with soybean oil gave the various effects on the cholesterol lowering rate in the serum and liver than single feeding of them.
The substantial change of the concentration and amount of carcass cholesterol in the rats fed various diets was not found in a series of experiments.View full abstractDownload PDF (13990K) -
