Effects of burdock inulin-type fructans exposure on the physiological function of healthy mice and their filial generation.

Inulin-type fructans (ITFs) have been shown to possess various biological activities. However, studies on their safety and side effects are limited. Hence, we aimed to evaluate the possible effects of burdock ITFs on the physiological indices of healthy mice and their filial generation when fed for six months. Thirty-two C57BL/6J mice were randomly divided into two groups; a normal control (NC) and an ITFs group. The parental generations were kept in one cage with free access to a normal diet and double-distilled water (P-NC group) or burdock ITFs drinking water (P-ITFs group, 2% w/v). The filial generations (F-NC group and F-ITFs group) were kept separately and were fed as their parental generation. Behavior, organ/body weight, serum indices, histopathology, time of production, and number of pup births were observed. There were no significant adverse effects on these indices. Functional indices of the spleen, lung, heart, and pancreas of the ITFs groups were higher than those of the NC groups, respectively. Interestingly, the serum glucose (GLU), total cholesterol (TC), uric acid (UA) and creatine kinase (CK) levels of the ITFs groups were lower than those of the NC groups. Meanwhile, the pregnancy number and pup birth number of the P-ITFs group were more than those of P-NC group. Therefore, long-term consumption of burdock ITFs has no obvious adverse effects on the health of parental mice and their offspring, but may contribute to reproductive capacity, fatigue reduction, and risk reduction of renal disease.
