Eating broiled or baked fish once a week means you're statistically 30 percent less likely to develop an irregular heartbeat (atrial fibrillation).

Dietary fish has also been shown to protect against ischemic stroke (stroke caused by blockage of blood supply to brain).

Broiled or baked fish intake increases blood levels of beneficial omega-3 essential fatty acid, but fried fish does not. Fish oil supplements may not provide the same benefits because there could be other unknown components of fish also involved.
