Fish consumption and risk of stroke.

Evaluation of: Larsson SC, Virtamo J, Wolk A: Fish consumption and risk of stroke in Swedish women. Am. J. Clin. Nutr. 93(3), 487-493 (2010). A population-based prospective study of 34,670 women in the Swedish Mammography Cohort was conducted, aiming to examine the associations between fish consumption and stroke incidence in women. After a mean follow-up of 10.4 years, 1680 cases of stroke were recorded. Fish consumption was inversely associated with risk of total stroke, but not cerebral infarction or hemorrhagic stroke. Compared with women in the lowest quintile of fish consumption, those in the highest quintile had a 16% lower risk of stroke. In addition, consumption of lean fish, but not of other fish types, was inversely associated with risk of stroke.
