Eating fish can save you from getting a stroke

Eating fish can save you from getting a stroke
NEW YORK (September 24, 2011): People who eat fish a few times each week are slightly less likely to suffer a stroke than those who only eat a little or none at all.
That’s the conclusion of an analysis of 15 studies, 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 Dr. 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.”
Close to 800,000 people in the U.S. have a stroke each year, and 136,000 die from it. Smoking, drinking, being overweight and having high blood pressure and cholesterol are all linked to a higher risk of stroke.
Dr. Susanna Larsson and Dr. Nicola Orsini of the Karolinska Institutet in Stockholm, Sweden wrote in the journal Stroke that omega-3 fatty acids in fish might lower stroke risk through their positive effects on blood pressure and cholesterol.

Vitamin D, selenium and certain types of proteins in fish may also have stroke related benefits

Vitamin D, selenium and certain types of proteins in fish may also have stroke-related benefits, Mozaffarian added.
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.
Mozaffarian’s own report separated the effects of different kinds of fish and found that people who ate more fried fish and fish sandwiches didn’t get any stroke benefit, not surprisingly.
But the research can’t prove that adding more non-fried fish to your diet will keep you from having a stroke.
Fatty fish such as salmon and herring are especially high in omega-3s. The American Heart Association recommends at least two servings of fatty fish in particular each week.
