Nutritional studies on the menu contained 70% polished rice and dietary restriction


Abstract
This study was designed to comparse the metabolic effects of Korean diet pattern which contained all-polished rice and 70961 polished rice, and to compare dietary restriction. The results were as follows.
1. Food intake survey to catch the Korean diet pattern
The calory intake showed women took much more than men and farm village was higher than city, However, protein intake showed men were higher than women and decreased gradually from city, fishing village, and farm village. Calcium intake showed Seoul was the first rank of all, but was merely 70% of recommended quantities. Fe intake was greatly short especially in women and vitamin C also showed same situation.
In the view of food group intake, grains and potatoes were 70.065vo, vegetables and fruits. 1 .05%, meats fishes and beans 11.99%, respectivelly. Oil and fat intake showed lowest percentage as 0.77%.
2. Nutritional experiments
albino rats have been fed for 7 weeks with three different diet: all-polished rice diet, 70% polished rice diet, and the standard diet for contral group. Dietary restriction were at 4 levels: 7 ,o , 10%, 15%, 20% in 70% polished rice det.
Body weight of 70% polished rice group gained value compare to all polished rice group.
In the final organ weight all-polished rice group and 70% polished rice group and 70500 polished rice group revealed similar results, but organ weight almost decreased dued to dietary restriction and statistical data showed significant differences between dietary restriction group and none-restriction group.
In the femur length, 7061 polished rice group was longer than all polished rice group but there was no significant differences.
The nitrogen content of liver and muscle of 70% polished rice group was higher than all-polished rice group. Furthermone there was significant differences in the female (p<0. 1). In the 1061 restriction group() and 15% restriction group(a), nitrogen retention was higher
n 0% re~riction group. -
The other biochemical analysis such as liver lipid, serum cholesterol, glucose of urine, feces and serum were not revealed any significant differences.
As a result of studying, it seems clear that 70% polished rice intake influenced much nourshment to white rat growth ;than all-porished rice intake, and there is no significant influence to animal growth and metabolic effect even if it was restricted 5^109ol of diet.
