What is high blood pressure? High blood pressure, or hypertension, is the pressure of blood against the artery walls. The condition can lead to health problems like heart disease, stroke, kidney disease and other issues. High blood pressure is often referred to as "the silent killer" because most people have no symptoms. According to the Centers for Disease Control and Prevention (CDC), nearly half of Americans have high blood pressure.

Changing your diet to include foods that may reduce blood pressure is an easy way to start the fight against hypertension. Some foods that may help lower blood pressure include leafy greens (romaine lettuce, arugula, kale, greens, spinach, swiss chard), berries (blueberries, raspberries, strawberries), beets, yogurt, oatmeal, bananas, fish (salmon, mackerel), seeds (sunflower seeds, pumpkin seeds, squash seeds), garlic, herbs, dark chocolate, pistachios, olive oil, pomegranates, sweet potatoes, beans, quinoa, broccoli, watermelon and cinnamon.
