Abstract

This study aimed to investigate the effect of resistant starch from green banana (GB) on steatosis and short-chain fatty acid (SCFAs) production in high fat diet-induced obesity in mice. High-fat green banana group (HFB) exhibited lower gains in BM (body mass; -6%; P < 0.01) compared with High-fat diet group (HF). Additionally, HFB mice showed reduction in liver steatosis (-28%, P < 0.01) with reduction of 93% in hepatic triacylglycerol (P < 0.01) compared to HF-diet-fed mice. In addition, the protein abundance of AMPKp/AMPK, HMGCoA-r and FAS were downregulated in livers of HFB mice (P < 0.01), relatively to the HF-diet-fed mice. ABCG8 and ABCG5 were up-regulated in HFB group compared to HF group (P < 0.01). Furthermore, the HFB fed-mice produced the highest amount of SCFAs (p < 0.05) compared to its counterpart HFD. In conclusion, we demonstrated that resistant starch from GB improved metabolic parameters by modulating the expression of key proteins involved in liver lipid metabolism.
