14 Best Foods for Reducing the Risk of Stroke
Stroke is one of the leading causes of death and disability worldwide. It occurs when the blood supply to the brain is interrupted, either due to a blockage (ischemic stroke) or bleeding (hemorrhagic stroke). However, strokes are largely preventable, and diet plays a significant role in lowering the risk. Eating the right foods can help keep your blood pressure, cholesterol levels, and blood sugar in check—three major risk factors for stroke. Incorporating nutrient-dense foods that promote cardiovascular health into your diet can help protect the brain and keep your arteries clear, reducing the likelihood of a stroke.
In this article, we’ll explore the 14 best foods that are proven to reduce the risk of stroke. These foods are rich in antioxidants, vitamins, and minerals that promote healthy blood flow, lower inflammation, and support overall heart health, ensuring your brain stays nourished and protected.
