Almonds

Almonds have gained a reputation as a heart-health superstar, and for good reason. Just a handful a day—around 23 nuts—can help lower LDL cholesterol, often called “bad” cholesterol, according to the American Heart Association. Recent research published in 2024 found that people who ate almonds daily saw a 7% reduction in LDL cholesterol over three months. Almonds are also high in vitamin E, an antioxidant that may help prevent plaque buildup in arteries. The healthy fats in almonds, mostly monounsaturated, support overall cardiovascular function and help keep inflammation in check. Their magnesium content can also play a role in maintaining healthy blood pressure. For anyone looking to snack smart, almonds are an easy, crunchy, and satisfying option.

Walnuts

Walnuts are unique because they are one of the only nuts that are a significant source of plant-based omega-3 fatty acids, specifically alpha-linolenic acid (ALA). Studies from 2023 found that regular walnut consumption can lower total cholesterol and improve blood vessel function, reducing heart disease risk by up to 15%. Walnuts also contain powerful antioxidants called polyphenols, which help fight oxidative stress and inflammation—two key factors in heart disease. Eating about a quarter cup of walnuts daily has shown benefits in clinical trials, according to data published in the journal Circulation. Their slightly bitter, earthy taste makes them perfect for salads or just a simple snack. Walnuts have even been linked to improved brain health, another bonus for your overall well-being.

Pistachios

Pistachios are more than just a fun snack—they’re packed with heart-protective nutrients like potassium, fiber, and phytosterols. A 2024 meta-analysis showed that people eating pistachios regularly saw significant drops in both systolic and diastolic blood pressure. They’re lower in calories than many other nuts, which makes them a good choice for those watching their weight. The high fiber content in pistachios helps reduce cholesterol absorption, while their antioxidant compounds help protect blood vessels from damage. Eating two ounces a day has been associated with improved lipid profiles in adults. The act of shelling them can even slow down snacking and help with portion control.

Pecans

Pecans are not just for pies—they are loaded with monounsaturated fats, which can help lower harmful cholesterol levels. According to a 2023 study from the University of Georgia, eating a small handful of pecans daily can reduce total cholesterol by up to 6%. Pecans are also rich in manganese and copper, minerals that support healthy blood vessels and a strong immune system. Their antioxidants, such as ellagic acid, help counteract inflammation and oxidative stress in the arteries. Because they’re naturally sweet, pecans make a heart-healthy topping for oatmeal or yogurt. Their versatile flavor profile means they can be used in both sweet and savory dishes.

Hazelnuts

Hazelnuts offer a delicious way to support cardiovascular health, thanks to their high content of monounsaturated fats and vitamin E. A 2024 review highlighted that daily hazelnut consumption can lower LDL cholesterol by about 9% without raising weight or blood sugar. Hazelnuts are also packed with folate, which helps regulate homocysteine levels—a compound linked to an increased risk of heart disease when elevated. Their crunchy texture and rich flavor make them a satisfying snack, and they’re easy to add to salads or desserts. Hazelnuts also contain magnesium, which supports healthy blood pressure. Regularly eating hazelnuts has been associated with improved artery flexibility and function.

Cashews

Cashews are creamy and mild, but don’t let their softness fool you—they’re loaded with nutrients that benefit the heart. They’re especially high in magnesium, which plays a crucial role in regulating blood pressure and heart rhythms. A 2023 randomized controlled trial found that participants who ate cashews daily saw a 5% drop in LDL cholesterol and improved HDL (“good”) cholesterol levels. Cashews also contain plant sterols, which have been shown to lower cholesterol absorption in the gut. Their copper content helps with iron metabolism and the maintenance of healthy blood vessels. While they are a bit higher in carbohydrates than other nuts, cashews still fit well into most heart-healthy diets when eaten in moderation.

Macadamia Nuts

Macadamia nuts are known for their buttery flavor and are especially rich in monounsaturated fats—over 80% of their fat content, which is higher than most other nuts. Studies from 2024 have shown that eating macadamia nuts can lower total cholesterol by up to 10% and specifically reduce LDL cholesterol. Their fat profile is similar to that found in olive oil, which is a staple of the heart-healthy Mediterranean diet. Macadamias are also a good source of thiamin and manganese, both important for heart and nerve function. Their antioxidants help reduce inflammation and protect artery walls from damage. While they are calorie-dense, a small handful can go a long way in delivering heart benefits.

Brazil Nuts

Brazil nuts stand out for their incredibly high selenium content—just one or two nuts a day provide more than the daily requirement. Selenium is essential for reducing inflammation and oxidative stress, both linked to heart disease risk. A 2023 clinical trial found that eating Brazil nuts improved cholesterol levels within just nine hours, making them one of the fastest-acting heart-healthy nuts. They also contain healthy fats and protein, supporting overall cardiovascular health. Because too much selenium can be harmful, it’s best to limit yourself to just one or two Brazil nuts a day. Their rich, creamy texture makes them a satisfying treat, and their unique nutrient profile is hard to beat.

Pine Nuts

Pine nuts, often found in pesto, are a surprising ally for heart health. They’re rich in monounsaturated fats, magnesium, and vitamin K, all of which play roles in heart protection. Research from 2024 suggests that regular pine nut consumption helps lower blood pressure and improve cholesterol levels. Pine nuts also contain pinolenic acid, a rare fatty acid that may help reduce appetite and support healthy weight—an important factor for heart health. Their vitamin E content works as an antioxidant, protecting blood vessels from damage. Because of their delicate, buttery taste, pine nuts are easy to sprinkle on salads or add to baked goods.

Peanuts, though technically legumes, are nutritionally similar to tree nuts and have been shown to provide significant heart benefits. A 2023 study published in the Journal of the American College of Cardiology found that people who ate peanuts several times a week had a 13% lower risk of heart disease. Peanuts are high in niacin and resveratrol, both of which support healthy blood flow and lower inflammation. Their plant-based protein and fiber help keep cholesterol in check and promote fullness. Peanuts are also a budget-friendly option, making heart-healthy eating accessible to more people. Dry-roasted or unsalted varieties are best for maximizing their benefits.
