Abstract

The effect of buckwheat dietary fiber (BDF) as hypolipidemic and antioxidant agent were determined in C57BL/6 mice fed a high fat diet (HFD) with different doses of 500 (low, BDF-L) or 1,000 (high, BDF-H) mg/kg of body weight, compared with the HFD-diet control group (HFD). The negative control group (ND) was fed the basal diet. Body weights in the BDF-L and BDF-H groups were significantly decreased as compared to those in the HFD group (p<0.05). BDF also improved the lipid profile in a dose-dependent manner; serum lipid profiles and levels of insulin, glucose, and free fatty acid were significantly decreased in the BDF-L and BDF-H groups, whereas HDL-C and adiponectin significantly increased as compared to the HFD group (p<0.05). Meanwhile, BDF lowered serum malondialdehyde (MDA) in comparison with the HFD group (p<0.05). The results demonstrate that the intake of BDF might prevent obesity and its related metabolic disorders by inducing dyslipidemia and oxidative stress.

고지방 식이로 고지혈증과 산화적 스트레스를 유도한 생쥐에서 메밀식이섬유의 개선 효과를 확인하고자 하였다. 고지방 식이와 함께 메밀식이섬유(저농도, 500 mg/kg; 고농도, 1,000 mg/kg)를 제공한 그룹의 체중은 고지방 식이만 제공한 그룹과 비교하여 유의적으로 감소하였다(p<0.05). 또한 메밀식이섬유를 제공한 그룹의 지질프로파일 개선 효과는 저농도에서 고농도로 용량 의존적으로 관찰되었다. 혈청 지질 프로파일과 인슐린, 포도당 및 유리 지방산의 수준은 메밀식이섬유 제공으로 유의하게 감소한 반면, HDL-C와 디포넥틴은 유의하게 증가했다(p<0.05). 한편, 고지방 식이만 제공한 그룹과 비교하여 메밀식이섬유 제공으로 혈청 말론다이알데히드(MDA) 수준이 농도 의존적으로 감소하였다(p<0.05). 결과적으로 메밀식이섬유의 섭취는 이상지질혈증과 산화 스트레스를 개선함으로써 비만과 관련 대사 장애를 예방할 수 있을 것으로 기대할 수 있었다.
