Abstract
Background: Crab-flavored seafood is a well-known traditional Japanese product that is sold as "imitation crab" worldwide. Although it is a low-cost, low-fat, high-protein food, there are few data on its potential health benefits. Here, we have assessed the effects of crab-flavored seafood consumption on organ weight and serum biomarkers levels in rats.
Methods: Sprague-Dawley rats (male; aged 6 weeks) were fed a normal diet (n = 8) or a normal diet with 5% dried crab-flavored seafood (n = 8) for 84 days. Food intake and overall body weight were measured every week; organ weight and blood biochemistry were evaluated at the end of the administration period.
Results: After 84 days, there were no significant differences in food intake, overall body weight, or organ weight between the 2 groups; however, the muscle weight of rats fed crab-flavored seafood tended to be higher than that of rats fed the normal diet. Several serum biomarkers did not differ between the 2 groups, but serum high-density lipoprotein, total bilirubin, and indirect bilirubin levels were significantly raised in rats fed crab-flavored seafood. Moreover, blood urea nitrogen was significantly lower, and some liver function parameters tended to be lower in rats fed crab-flavored seafood.
Conclusions: Consumption of crab-flavored seafood may be effective for promoting muscle protein synthesis and improving serum biomarkers associated with disorders such as cardiovascular disease and stroke. Thus, crab-flavored seafood may have application as a functional food for the global management of human health.
期刊介绍:
Nutrition and Metabolic Insights is a peer-reviewed, open-access online journal focusing on all aspects of nutrition and metabolism. This encompasses nutrition, including the biochemistry of metabolism, exercise and associated physical processes and also includes clinical articles that relate to metabolism, such as obesity, lipidemias and diabetes. It includes research at the molecular, cellular and organismal levels. This journal welcomes new manuscripts for peer review on the following topics: Nutrition, including the biochemistry of metabolism, Exercise and associated physical processes, Clinical articles that relate to metabolism, such as obesity, lipidemias and diabetes, Research at the molecular, cellular and organismal levels, Other areas of interest include gene-nutrient interactions, the effects of hormones, models of metabolic function, macronutrient interactions, outcomes of changes in diet, and pathophysiology.
