Abstract

The hypolipidemic and organ protective potentials of consuming tropical red seaweed, Gracilaria Changi, were determined. We also evaluated the histopathological effects and safety on the organs (liver, kidney and heart) in male Sprague Dawley rats fed with a [1] normal diet (NF), NF supplemented with [2] 5% or [3] 10% G. Changi powder, [4] high cholesterol/fat diet (HF), and HF supplemented with [5] 5% or [6] 10% G. Changi powder and [7] Atorvastatin. Microscopic examination revealed that G. Changi supplementation in the HF diet ameliorated the histological changes in the rat liver cells, and this group had lower levels of hepatic steatosis and inflammatory infiltration compared to the HF group. No adverse effects were observed in the organs of NF rats that consumed G. Changi. Thus, G. Changi had protective effects against induced hyperlipidemia and could improve the hyperlipidemia-associated alterations in organ structures. These findings suggest that G. Changi could be used as a functional food ingredient for human consumption.
