Can eating fish lower the risk of strokes? By Elaine Lies | Reuters – Mon, Sep 26, 2011
“Their analysis was based on 15 studies conducted in the United States, Europe, Japan and China, each of which asked people how frequently they ate fish, then followed them for between four and 30 years to see who suffered a stroke.
“I think overall, fish does provide a beneficial package of nutrients, in particular the omega-3s, that could explain this lower risk,” said Dariush Mozaffarian, a Harvard School of Public Health epidemiologist whose research was included in the analysis.
“A lot of the evidence comes together suggesting that about two to three servings per week is enough to get the benefit.”
Vitamin D, selenium, and certain types of proteins in fish may also have stroke-related benefits, he added.
Data for the analysis came from close to 400,000 people aged 30 to 103.
Over anywhere from a few years to a few decades, about 9,400 people had a stroke. Eating three extra servings of fish each week was linked to a six-percent drop in stroke risk, which translates to one fewer stroke among a hundred people eating extra fish over a lifetime.
The people in each study who ate the most fish were 12 percent less likely to have a stroke than those that ate the least.
Mozaffarian’s report separated the effects of different kinds of fish and found that people who ate more fried fish and fish sandwiches, not surprisingly, didn’t get any stroke benefit.
But the research can’t prove that adding more non-fried fish to your diet will keep you from having a stroke, Mozaffarian told Reuters Health.
People “could have healthier diets in other ways, people could exercise more, people could have better education that could lead them to see their doctors more,” he added, all of which could decrease their risk of strokes.
