Can unhealthy eating cause a stroke?

Yes. Food that can lead to high blood pressure or high cholesterol increases the chances of a person suffering from a stroke.

Ischemic strokes are caused by thrombus or embolus blood clots that blocks the blood flow to the brain. Thrombus clots usually occur in areas of the arteries that have been damaged by atherosclerosis from a buildup of plaques. Embolus type blood clots on the other hand are often caused by atrial fibrillation (an irregular pattern of heart beat that leads to blood clot formation and poor blood flow).

Unhealthy eating causes plaque to buildup in the arteries.
