The relation between fish consumption, death from all causes, and incidence of coronary heart disease. the NHANES I Epidemiologic Follow-up Study.

1 time/week (adjusted relative risk 0.85, 95% CI 0.68-1.06). Similar but nonsignificant trends were seen in white and black women, but not black men. In white men, risk of noncardiovascular death but not cardiovascular death was also significantly reduced in those consuming fish once or more a week. No consistent association of fish consumption and coronary heart disease incidence or mortality was seen. White men consuming fish once a week had significantly lower risk of death over a 22-year follow-up than those never consuming fish. This was mostly attributable to reductions in death from noncardiovascular causes. Similar patterns, though not significant, were seen in women. Further studies are needed to confirm these findings and to elucidate mechanisms for the effect of fish consumption on noncardiovascular mortality.
