"Your pantry is your first line of defense against foodborne illness and things like high blood pressure and cholesterol." - Joe Bastianich
High blood pressure, also known as hypertension, is called the “silent epidemic.” That’s because so many people have it. But because it rarely shows any warning signs or symptoms, it’s easy to miss if you’re not looking out for it. According to the CDC (Centers for Disease Control and Prevention), almost half of the adults in the US have hypertension, and most don’t have it under control. In 2019, this resulted in over half a million deaths. High blood pressure can be very dangerous because it increases your risk for a heart attack, stroke, kidney disease, and blindness. This is why regular blood pressure screenings and a healthy diet and lifestyle are so important. This post is going to show you how.
The foods you eat affect so many aspects of your health, and it's never too late to start enjoying a more "heart-healthy" diet. In fact, one diet has been specially designed to help with high blood pressure. That's called the DASH diet: Dietary Approaches to Stop Hypertension. And research says it works.
Disclaimer: If your doctor recommends medication to help you control your blood pressure, be sure to take it as directed and go for routine monitoring or testing as required. Practice Dr. Sear's "Pills and Skills" model of continuing your medication as directed while implementing new healthy lifestyle, exercise, attitude, and nutrition behaviors.
What is blood pressure?
Blood pressure is how much pressure your heart needs to use to keep blood flowing through your vessels. You can think of it as water flowing through a flexible tube versus a stiff, rigid, narrow pipe. The flexible tube will expand to allow more water flow, whereas the rigid pipe requires more water force. The more pressure put on your vessels, the more damage it can do to the pump and the vessels. This is especially true when high blood pressure persists over many years.
A normal blood pressure reading is 120/80 mm Hg. The first number (in this case, 120 mm Hg) is the systolic pressure in your vessels as your heart beats. The second number (in this case, 80 mm Hg) is the diastolic pressure in your vessels between beats. If your blood pressure is slightly higher than these numbers, that's considered "elevated." However, if your blood pressure gets above 130/80 mm Hg, you may be diagnosed with Hypertension.
High blood pressure usually develops over many years. It can result from diabetes or obesity or not getting enough physical activity. It can also sometimes happen during pregnancy.
The good news is that there are ways you can manage high blood pressure and lower your risk for heart disease (angina, heart attack, heart failure), stroke, kidney disease, and vision loss.
Healthy lifestyle for healthy blood pressure
Several healthy lifestyle habits can lower your risk for high blood pressure. The first is to not smoke because smoking is associated with many issues, including heart issues.
Another lifestyle habit for healthy blood pressure (and overall health) is getting at least 150 minutes of physical activity every week. That can be done with as little as 30 minutes per day, five days per week.
Positively managing stress is another strategy to help maintain healthy blood pressure.
Sodium and your blood pressure
Your nutrition impacts your blood pressure. Several nutrients can increase or decrease your blood pressure, depending on your consumption. The nutrients associated with lower blood pressure include the minerals potassium, magnesium, calcium, fiber, and protein. The most famous nutrient linked to increased blood pressure is sodium.
According to the American Heart Association, in general, the more sodium you consume, the higher your blood pressure. Sodium is one part of the salt compound, sodium chloride. One of the most significant sources of sodium in the diet is not from your kitchen salt shaker, but the sodium hidden in processed and packaged foods.
A recent study enrolled 20,995 participants with a history of stroke or high blood pressure to see if using a lower-sodium salt substitute would reduce their risk of stroke, heart incidents, and death. Half of the participants continued to use regular salt over several years, while half agreed to use the salt substitute (75% sodium chloride and 25% potassium chloride). After almost five years, the participants who consumed the lower-sodium salt had fewer strokes, heart incidents, and deaths. Their risks were reduced by 12-14%, which is substantial when there are millions of people at high risk from Hypertension.
The DASH diet
A dietary pattern and food recommendation have been put together specifically for Hypertension. The DASH diet has been deemed one of the best overall diets by U.S. News and ranked among the top diets in the categories of heart-healthy, healthy eating, diabetes, easy-to-follow, and overall diets. Harvard Health also rated the DASH diet and said, "research supports the use of the DASH diet as a healthy eating pattern that may help to lower blood pressure, and prevent or reduce the risk of cardiovascular diseases, diabetes, kidney disease, and gout." Some studies show that the blood pressure-lowering effect of the DASH diet can be similar to that of people taking medication for stage 1 hypertension.
The DASH diet is full of heart-healthy foods with blood-pressure-lowering nutrients. The recommendations for a 2,000 calorie per day intake include:
● whole grains (6-8 servings/day)
● fruits (4-5 servings/day)
● vegetables (4-5 servings/day)
● low-fat dairy (2-3 servings/day)
● lean meat, poultry, or fish (no more than two 3 oz servings/day)
● fats and oils (2-3 servings/day)
● nuts, seeds, or beans (4-5 servings/week)
● sweets and sugar-sweetened beverages (no more than five servings/week)
As mentioned, the health benefits of eating a DASH diet are vast and include many of the most common diseases impacting adults.
When transitioning to a higher-fiber diet with more whole grains, fruits, and vegetables, one thing to keep in mind is to do this slowly to reduce your risk of experiencing gas and bloating. A slower transition can accomplish this by increasing these plant-based foods by one or two per week until you eat the recommended amounts.
Final thoughts
If you have high blood pressure or want to start a healthier diet to reduce your risk for a whole host of diseases, then the DASH diet may be for you. The DASH diet is rich in foods that are highly nutritious and can help you enjoy a longer life free of stroke, heart disease, kidney disease, blindness, diabetes, and gout.
The DASH diet is considered one of the easiest diets to follow and includes simple nutritional improvements like enjoying more whole grains, fruits, and vegetables.
