Diet can prevent diabetes in the BB rat

Abstract

When compared with laboratory chow, a defined, semipurified diet prevented diabetes, reduced the frequency of insulitis, increased thymus weight and total white blood cell count, and doubled thymus T-helper/T-suppressor cell ratios in diabetes-prone BB rats. These data show that the diabetic syndrome in BB rats may be prevented or delayed by changes in diet, which may occur through alteration of pathogenic defects in the immune system.
