Many people reach for chips or cookies when they want a quick snack, often without considering the impact these foods can have on overall health.
According to cardiologists speaking to Parade, pistachios offer a healthier alternative that may support both blood pressure levels and long-term heart health.
Ultra-processed snacks may raise the risk of high blood pressure
Research published in Advances in Nutrition has linked ultra-processed foods to a higher risk of heart disease, obesity, and elevated blood pressure.
A separate study published in Public Health Nutrition found that the risk of hypertension increases with greater consumption of ultra-processed products.

Popular snacks are often high in sodium
Cardiologist Dr. Kainat Khalid told Parade that many common snack foods contain excessive amounts of sodium, added sugar, and saturated fat. Products such as chips and crackers are among the biggest concerns.
Many processed foods are designed to encourage overeating
Dr. Khalid explained that highly processed snacks are often engineered to be especially appealing, making it easy for people to consume several servings without noticing.
Pistachios provide a healthier option
Dr. Kainat Khalid and Dr. Allen J. Taylor highlighted pistachios as a nutritious alternative for people looking for the same crunchy texture as chips, but with added health benefits.
Rich in healthy fats
Pistachios contain unsaturated fats and omega-3 fatty acids, nutrients that may help blood vessels relax and widen. Improved circulation can reduce pressure on the cardiovascular system.

May improve blood vessel function
Research published in the Asia Pacific Journal of Clinical Nutrition suggests that pistachios may improve the flexibility and responsiveness of blood vessels, helping the heart work more efficiently.
Contain important minerals
According to Dr. Khalid, pistachios are also a source of magnesium and potassium, two minerals that play an important role in regulating blood pressure and maintaining electrolyte balance.
Studies show positive effects on blood pressure
A 2022 review published in Nutrition Reviews, which analyzed 17 studies involving 940 adults, concluded that pistachios may have beneficial effects on blood pressure levels.
Unsalted pistachios are recommended
The cardiologists emphasized that unsalted pistachios are the best choice for people who want to maximize the potential heart-health benefits.

Too much salt can reduce the benefits
While salted pistachios still contain valuable nutrients, the additional sodium may counteract some of the positive effects on blood pressure, particularly in people who are sensitive to salt.
May also support healthy cholesterol levels
Dr. Khalid noted that the unsaturated fats found in pistachios may help reduce LDL cholesterol while preserving HDL cholesterol levels.
Moderation is still important
Dr. Khalid recommends eating a small handful of pistachios each day.
She also warned that even healthy snacks should be consumed in moderation to avoid excessive calorie intake.
