This Popular ‘Healthy’ Snack May Be Worsening Your Hypertension, Cardiologists Warn

High blood pressure is incredibly common, affecting nearly half of U.S. adults. Certain medications—thankfully—can help people manage hypertension, lowering their odds of further heart health issues. However, cardiologists emphasize that lifestyle tweaks, particularly dietary changes, are crucial to maintaining blood pressure levels within a normal range.“Diet plays a key role because what we eat directly affects blood pressure through mechanisms like sodium (salt) balance, blood vessel health and body weight,” explains Dr. Deepak Talreja, MD, the clinical chief of cardiology for Sentara Health. “By making healthy food choices, people can lower their blood pressure naturally, sometimes even reducing the need for medication.”Unfortunately, sometimes people think they are making a healthy choice by reaching for certain snacks that can actually make hypertension worse. Cardiologists warn that this one snack has a better reputation for heart health than it should.

This ‘Healthy’ Snack Can Worsen Hypertension, Cardiologists Say

Cardiologists warn that people often overlook the high salt content in pretzels, which check other “heart-healthy” boxes. However, they don’t recommend consuming tons of pretzels regularly if you have high blood pressure (or want to avoid it).“Pretzels have a misleading image of being healthy because they are low-fat—they contain less than 2 grams of fat per serving,” shares Dr. Aaron Feingold, MD, the chair of cardiology at JFK University Medical Center. “Unlike potato chips, pretzels are baked, which consumers view as a healthier preparation method.”Specifically, Dr. Talreja warns that brands that make pretzels typically stamp phrases like “0 grams of saturated fat” on the front of the bag. While the American Heart Association and cardiologists agree that it’s important to check the nutrition label for saturated fat, it’s not the be-all, end-all clue that a snack is heart-friendly.

“Low-fat foods have been historically touted as ‘healthy,'” explains Dr. Christopher Berg, MD, a board-certified cardiologist at MemorialCare Heart and Vascular Institute at Orange Coast Medical Center. “While there is some truth to this, as saturated fats can be strongly associated with LDL-C levels and fats are calorie-dense and can lead to weight gain, the sodium content, the most important dietary parameter for modulation of blood pressure, may be overlooked. For those who are sensitive to dietary sodium intake, pretzels may not be a healthy choice.”
