Protect your brain from stroke
Reducing your salt intake may help.
You've heard for years that too much salt can raise your blood pressure and is dangerous for the heart. A new study finds that salt may also be a threat to your brain. The study, published in the journal Stroke, finds that among older adults, a high-sodium diet can significantly raise the risk of stroke. "The findings are associations and don't prove causality," says Dr. Helen Delichatsios, assistant professor of medicine at Harvard Medical School. "But I don't think the concerns about excess salt intake are overrated."
Stroke and salt
A stroke occurs when an artery that supplies blood to the brain becomes blocked or bursts. Without blood, brain cells go without oxygen and begin to die.
