ABSTRACT
Fish sausage is a common food in Japan. It is mainly made from <i>surimi</i>, which contains a high amount of fish protein. Although it has been reported that the administration of fish protein reduces blood total cholesterol, LDL-cholesterol, and triglycerides in experimental animals, it has not been studied whether the intake of fish protein improves blood cholesterol profiles in humans. In the present study, male subjects (n = 20) with fasting blood LDL-cholesterol (140–179 mg/dL) were enrolled. Subjects consumed a total of 225 g of fish sausage daily for 8 weeks, and the total ingestion dose of fish protein was 13.5 g/day. Blood total cholesterol, LDL-cholesterol, and atherogenic index were significantly reduced (<i>p</i> < 0.01, <i>p</i> < 0.05, and <i>p</i> < 0.01, respectively), and HDL-cholesterol was significantly increased (<i>p</i> < 0.01) by fish sausage intake after 4 and/or 8 weeks of intervention without side effects. These results imply that the short-term intake of fish protein achieved by the eating of fish sausage improves cholesterol profiles in hypercholesterolemia subjects.<br>
