Objectives

Narrative objectives1

The health benefits of fish are clear, as there are many reports of fish oil's effectiveness in reducing the risk of cardiac disease and improving cognitive performance, among a wide range of other benefits, but the guidelines for fish consumption are not explicitly stated. In addition, although fish is an important source of protein for Japanese people, there are not many reports on its usefulness. In order to clarify the relationship between fish-derived protein intake and health indicators among Japanese, this study will examine the relationship between fish intake and body composition and health-related indicators among the registered users of the health application "Asuken.
