DASHing our way to Stroke Prevention

When it comes to stroke prevention, the secret may lie with the Dietary Approaches to Stop Hypertension. DASH is an eating pattern that emphasizes fresh fruits and vegetables, leaner proteins, nuts/seeds, low/non-fat dairy products, and whole grains. The underlying secret to DASH’s stroke-preventing abilities relies upon three nutrients that reduce blood pressure: magnesium, calcium, and potassium1,2,3.

Magnificent Magnesium

Magnesium is an extremely important nutrient that is responsible for many of the chemical reactions that occur in the body, in addition to controlling blood pressure. It is most commonly found in dark leafy greens such as kale, spinach, and Swiss chard. Each of these veggies can help supply the body with the magnesium it needs, and for very few calories to boot! Nuts/seeds, soybeans, avocados, and dark chocolate are additional delicious sources of magnesium. To eat according to the DASH principles, consume 4-5 servings of vegetables a day and 6-8 servings of whole grains per day. By doing this, you can meet your body’s needs for magnesium4.

Charismatic Calcium

Calcium is another essential nutrient that plays a key role in blood pressure maintenance5. It’s easy to come by if you eat dairy products, dark leafy greens, figs, fortified breads & cereals, fish, and soybeans. Increasing calcium intake has even been shown to offset the effect of salt in the diet, a known culprit in elevated blood pressure that increases our risk for stroke6. It’s important note that the body can’t absorb Calcium without Vitamin D, so try to consume 2-3 servings of calcium and vitamin D-rich dairy products per day to help your body absorb the calcium it needs to reduce your risk for stroke!

Powerful Potassium

Studies suggest that potassium lowers blood pressure by making our arteries more flexible while allowing the body to relieve itself of excess sodium7. Potassium is found in potatoes, squash, mushrooms, dark leafy greens, beans, soybeans, and non/low-fat dairy products. Bananas are another rich source for potassium and can help you meet the 4-5 daily servings of fruit recommended by DASH. Nuts/seeds are another source of potassium – DASH recommends that we eat 4-5 servings of nuts/seeds throughout the week (since nuts are a very calorie dense food, remember a serving of this group is equal to 1/4 cup)8.

No equation or formula will completely eliminate your risk for stroke. However, when combined with a healthy and active lifestyle, the D.A.S.H. diet can certainly aid in our quest for stroke prevention!
