The link between chronic stress and blood pressure isn’t completely clear, though we do know that in times of immediate stress, the body’s fight or flight mechanism kicks in, pumping up stress hormones (adrenaline and cortisol), which raises blood pressure. To maintain an even keel after temporary spikes in blood pressure, look to potassium-rich foods. Dried spirulina powder is a novel option for potassium, and a little goes a long way: It only takes three to four tablespoons to add a significant amount of potassium to the diet. Add it to smoothies, dips, juices, baked goods and soups. If spirulina is outside your comfort zone, go for avocados, bananas, beans, beet greens, chocolate, edamame, milk, mushrooms, orange juice, spinach, sweet potatoes and yams.
