Abstract

The beneficial health effects of edible sea urchin consumption in mice fed a normal (ND) or high-fat diet (HFD) were investigated in this study. Notably, sea urchin-administered (250, 500, 1000 mg/kg) mice exhibited lower body, liver, and visceral fat weights, lower plasma levels of aspartate aminotransferase and alanine aminotransferase, and lower hepatic triacylglycerol levels than those fed carboxymethyl cellulose (CMC). Despite the high levels of cholesterol found in sea urchins, intake of these organisms had no effect on plasma cholesterol levels among the mice tested. Additionally, sea urchin consumption resulted in enhanced levels of arachidonic acid and docosahexaenoic acid within mouse livers. Lastly, mice fed HFD with sea urchin (500 mg/kg) exhibited increased mRNA expression of uncoupling protein-1 within brown adipose tissue, compared with those fed HFD with CMC. In conclusion, consumption of sea urchin might provide a protective effect against the development of obesity and/or nonalcoholic fatty liver disease.
