Protective effect of bamboo root dietary Fibre on hyperlipidaemia mice induced by high-fat diet

Bamboo root as by-product of bamboo shoot processing is rich in dietary fibre. The protective effects of bamboo root dietary fibre (BRDF) with different intake dose on the hyperlipidaemia mice were investigated. The mice weight in the high dose (HD) group was 31.18 g, lower than that of high fat diet (HFD) group (33.71 g, p < .05), after consuming BRDF. The contents of TC, TG and LDL-C in HD group mice were significantly reduced (p < .05). The mice liver index significantly decreased in the BRDF group compared to the HFD group. TC and TG contents in the liver of HD mice were 0.85 mmol<middle dot>g(-1) and 0.83 mmol<middle dot>g(-1), respectively, significantly lower than 2.25 mmol<middle dot>g(-1) and 1.46 mmol<middle dot>g(-1) in the normal control group (p < .05). H&E staining showed a reduction in inflammatory infiltration. These results suggested that BRDF in the daily diet could reduce blood lipids in vivo and prevent hyperlipidaemia.{GRAPHIACAL ABSTRACT}
