Effects of processed rye bran and raw rye bran on glucose metabolism in alloxan diabetic rats.

Alloxan diabetic rats (D) and control rats (C) were for 14 days fed a basic diet made from a mixture of rye bread and milk containing either no bran (group O), processed bran (group PB) or raw bran (group B). The D-B animals has a lower urinary glucose excretion (36 +/- 4 mmoles/24 hours) than the D-PB animals (63 +/- 5 mmoles/24 hours), which in their turn had a lower excretion than the D-0 animals (100 +/- 3 mmoles/24 hours). The effects of the two brans on weight, serum insulin levels, and non-fasting blood glucose levels were similar in D-rats as well as in C-rats, with the exception of the lower nonfasting blood glucose level in C-B animals than in C-PB animals.
