How Nuts Can Help With Blood Pressure

Nuts, including almonds, pistachios, and peanuts, contain a unique blend of nutrients, emerging as powerful allies in the fight for blood pressure control. High blood pressure affects many individuals, and it’s a major risk factor for heart disease, but incorporating heart-healthy foods like nuts into your diet can actually help lower high blood pressure. We’ll explain the science behind how, and we’ll explore the specific benefits of nut varieties, so you can make informed choices and incorporate these delicious powerhouse foods into your diet for a healthier you.

The Power of L-Arginine: How Nuts Lower Blood Pressure

Nuts and peanuts hold a secret weapon in the fight against high blood pressure: L-arginine. This essential amino acid plays a dual role. It not only aids in protein building but also helps relax blood vessels. As these vessels dilate, blood flow improves, leading to a natural decrease in blood pressure.

Studies have shown L-arginine's effectiveness in lowering blood pressure for individuals with:

  • Mild to moderate hypertension
  • Hypertension with diabetes
  • Pulmonary hypertension

But the benefits of nuts extend beyond blood pressure control. Nuts rich in L-arginine may offer these additional advantages:

  • Reduced symptoms of mild angina (chest pain caused by reduced blood flow to the heart)
  • Improved blood flow in people with Peripheral Arterial Disease (PAD)

By incorporating nuts and peanuts into your diet, you can leverage the power of L-arginine for a healthier heart and improved blood pressure control.

The Best Nuts for Lowering Blood Pressure

While many nuts offer heart-healthy benefits, some excel in supporting healthy blood pressure. Here's a breakdown of the best nuts for high blood pressure.


A budget-friendly option, peanuts contain high levels of resveratrol, phytosterols, magnesium, and potassium—all-stars in blood pressure reduction, particularly the diastolic pressure (bottom number). Peanuts are good for blood pressure and they offer a wealth of health benefits. Their plant protein aids in type 2 diabetes prevention, their antioxidants shield your heart, and the fiber in peanuts keeps you feeling full, promoting weight management.


These tiny green gems are packed with heart-healthy fats and have been shown to significantly reduce both systolic (top number) and diastolic blood pressure, making them one of the best nuts for heart health. Additionally, their high antioxidant content provides a protective layer against heart disease. Plus, pistachios have the lowest calorie count per ounce compared to other nuts on this list, making them an ideal snack.


When it comes to nuts and heart health, almonds are excellent for promoting blood vessel dilation, and can contribute to lowering systolic blood pressure. They're a rich source of magnesium, a mineral often recommended for blood pressure management. Don't forget their fiber content, which also helps lower blood pressure and reduce inflammation.


Don't be fooled by their deliciousness! The cashew is a powerhouse of heart-healthy monounsaturated and polyunsaturated fats, which effectively lower blood pressure. They're also brimming with protein, magnesium, and potassium, all contributing to better blood pressure control. Additionally, cashews have the lowest total fat content per ounce compared to the other nuts listed.

Remember: A balanced approach is best. Include a variety of these nuts in your diet for a well-rounded intake of the beneficial nutrients they offer.

Nuts: Heart Health Beyond Blood Pressure Control

While nuts and peanuts are good for lowering high blood pressure, they also offer a variety of advantages for your heart and health:

  • Taming "Bad" Cholesterol and Triglycerides. Nuts, rich in healthy fats and fiber, act like tiny sponges, soaking up LDL ("bad") cholesterol and triglycerides that can contribute to artery blockage.
  • Quieting Inflammation. Chronic inflammation is linked to an increased risk of heart disease. Nuts' anti-inflammatory properties have a positive effect by helping reduce stress on the heart.
  • Strengthening Artery Walls. The healthy fats and antioxidants in nuts contribute to maintaining the health and elasticity of your arteries.
  • Reducing Blood Clot Risk. Nuts may help reduce the formation of blood clots, potentially lowering your risk of heart attack and stroke.

Moderation is Key: Remember, even though nuts include mostly "healthy" fats, they are still calorie-dense. To leverage their benefits for blood pressure and overall heart health, eat nuts in moderation. Aim for the recommended serving size: four to six 1.5-ounce (42.5g) portions per week. Additionally, opt for unsalted nuts. Consuming too much sodium can increase blood pressure levels, making hypertension even worse.
