J. Kashimura et al., THE EFFECTS OF ISOMALTULOSE-BASED OLIGOMERS FEEDING AND CALCIUM DEFICIENCY ON MINERAL RETENTION IN RATS, Journal of nutritional science and vitaminology, 42(1), 1996, pp. 69-76
We examined the effects of isomaltulose-based oligomers (IBOs) on the
mineral content of the whole blood, kidney, liver and tibia in calcium
deficient and calcium sufficient rats. Twenty-eight Wistar rats were
divided equally into 4 grups and fed with the following diets ad libit
um for 4 weeks: (1) calcium sufficient diet (Ca+, IBOs-), (2) calcium-
sufficient-IBOs supply diet (Ca+, IBOs+), (3) calcium-deficient diet (
Ca-, IBOs-), (4) calcium-deficient-IBOs supply diet (Ca-, IBOs+). Ther
e were no significant differences in final body weights among the grou
ps. Food consumption in the calcium-deficient groups was higher than t
hat in the calcium-sufficient groups. The tibia weight was significant
ly decreased, and the calcium, magnesium and phosphorous contents were
significantly decreased, and iron content was significantly increased
in the tibia of calcium-deficient rats. On the other hand, in IBOs fe
eding rats, tibia weight, and calcium, magnesium and phosphorous conte
nts were significantly increased, and iron content was significantly d
ecreased. These findings suggest that IBOs feeding improves mineral re
tention especially in a state of calcium deficiency.
