Dietary factors that can help manage blood pressure include increased intake of fruits, vegetables, whole grains, and low-fat dairy. The DASH diet (Dietary Approaches to Stop Hypertension) emphasizes these foods while reducing sodium and saturated fats. Consuming foods rich in potassium, like bananas and spinach, can also contribute to lowering blood pressure. Regular meal patterns and portion control are vital for maintenance, along with reducing processed and sugary foods that can contribute to higher blood pressure.
