The scientists studied middle-aged men who had a high risk of stroke or other cardiovascular disease. Physicians at UT Southwestern Medical Center at Dallas and other health experts say people who smoke, have high blood pressure and are overweight, have a higher than average risk of stroke. The fatty acid study concluded that increasing the intake of alpha-linolenic acid lowered the risk of stroke significantly. Researchers don't know exactly how the fatty acid works to lower the risk. But they do know that a family of fatty acids that come from it, called the omega-3 fatty acids, help reduce clotting in the arteries.
Stroke is caused by arterial clots which block blood flow to the brain.
Researchers say the key to stroke prevention is to eat a balanced diet featuring a variety of fruits and vegetables, keep your blood pressure low and avoid smoking.
