Fish consumption and risk of stroke: A second prospective case-control study from northern Sweden

Seems odd since we have this other research suggesting cold water fish lowers stroke risk. Maybe the full article links directly to the study showing a stroke risk, I prefer to analyze these studies myself. I have 8 posts on fish and 63 on fish oil so you can figure out for yourself what your diet protocol for fish and fish oil should be. No one else is going to do this for you because of all the incompetence in the stroke world.

Why eating fish might be better supplements for stroke risk

Fish consumption and risk of stroke: A second prospective case-control study from northern Sweden

Nutrition Journal, 11/29/2016 Wennberg M, et al.

In this study, researchers aim to investigate if previous results on elevated stroke risk with high fish consumption in men in northern Sweden can be confirmed in a larger study with new cases in the same population. As per this study, the previous association between high total fish consumption and risk of stroke in men could not be repeated. In men, the increased risk found with a high intake of lean fish might be due to chance or confounding specific for this group.

Methods

• The researchers performed a prospective nested case-control study within the population-based Northern Sweden Health and Disease Study cohort.
• At baseline, information on fish consumption, other lifestyle and medical data were collected.
• They identified incident stroke cases (1987–2007, n = 735) and 2698 controls matched for gender, age, year of baseline and geographical region.

Results

• No associations was found between total fish or fatty fish consumption and stroke risk; in this manner the previous finding of increased risk of stroke with high fish consumption in men could not be repeated.
• In men, high intake of lean fish (>twice/week compared to < once/month) was associated with increased stroke risk [OR 1.80 (95% CI 1.00, 3.21), but not in women [OR 0.50 (95% CI 0.24, 1.10)].
• The study reveals that the association was driven by men living alone.
