Fatty fish but not lean fish consumption is associated with reduced risk of coronary heart disease: A meta-analysis of prospective cohort studies

Abstract

Background and Aims : Fish consumption is associated with reduced risk of coronary heart disease (CHD), partly for its high content in long-chain n-3 polyunsaturated fatty acids. However, not all fish species are equally rich in these components, and it is not clear whether the beneficial effects of fish consumption occur with both fatty and lean fish. The aim of this meta-analysis is to evaluate the relation between intake of fatty fish or lean fish and the risk of CHD incidence and mortality.
