1. Almonds: The Undisputed Nutrition Champion
Almonds often take the crown as the healthiest nut—and for good reason. Packed with vitamin E, magnesium, and fiber, almonds help support brain health and lower cholesterol. One ounce of almonds (about 23 nuts) provides around 6 grams of protein and 14 grams of fat, most of which are heart-healthy monounsaturated fats. Recent studies, like the 2023 review in the journal Nutrients, highlight almonds’ ability to reduce LDL (bad) cholesterol and support healthy blood sugar levels. According to the American Heart Association, regular almond consumption may also decrease inflammation. Their crunch and slightly sweet flavor make them a favorite snack, and they’re easy to add to yogurt, oatmeal, or salads. People aiming for weight loss often turn to almonds because of their high fiber and protein, which help with feeling full. As a bonus, almonds are widely available and affordable.
2. Walnuts: Omega-3 Powerhouse
Walnuts are often praised for their unique nutrient profile, particularly their very high content of ALA omega-3 fatty acids—more than any other nut. Just a handful (about 1 ounce or 14 halves) delivers 2.5 grams of ALA, which is vital for brain and heart function. According to a 2024 Harvard study, eating walnuts regularly was linked to lower rates of heart disease and improved cognitive performance in older adults. Walnuts also contain polyphenols, which are antioxidants that help fight inflammation. Their slightly bitter taste and crinkled shape make them popular in baked goods, but they’re just as good raw or tossed on salads. They’re a little higher in calories than almonds, but their benefits for heart health and the brain are hard to beat. Walnuts also contain melatonin, which supports better sleep.
3. Pistachios: The Protein-Rich Snack
Pistachios are more than just a fun food to crack open—they’re incredibly healthy, too. One ounce (about 49 nuts) provides 6 grams of protein and 3 grams of fiber, making them one of the most filling nuts you can eat. In 2023, a study published in the journal Nutrients confirmed that pistachios are linked to better blood sugar control and lower triglyceride levels. They’re also rich in lutein and zeaxanthin, two antioxidants that protect your eyes from damage. Unlike many other nuts, pistachios are lower in fat, with most of it being the heart-healthy kind. Their bright green color isn’t just for looks—it’s a sign of the powerful antioxidants inside. Plus, because they’re often eaten in the shell, you tend to eat them more slowly and mindfully, which can help with portion control.
4. Cashews: Creamy, Versatile, and Nutrient-Dense
Cashews are known for their buttery texture and versatility in recipes, from creamy sauces to vegan cheese. They’re a great source of copper, which helps your body absorb iron, and they also contain magnesium and zinc. One ounce of cashews (about 18 nuts) provides about 5 grams of protein and 12 grams of fat. New research in 2024 has shown that cashews might help improve heart health by lowering blood pressure and increasing good HDL cholesterol. While they’re a bit higher in carbohydrates compared to other nuts, their rich taste makes them a favorite for snacking and cooking. Cashews are also a good source of plant-based iron, making them especially valuable for vegetarians. Just be careful not to eat them salted or roasted in oil, as this can add extra sodium and calories.
5. Hazelnuts: The Heart-Healthy Treat
Hazelnuts don’t get as much attention as almonds or walnuts, but they’re a quiet powerhouse. One ounce (about 21 nuts) offers 4 grams of protein and 3 grams of fiber, plus a hefty dose of vitamin E and manganese. A 2024 meta-analysis in the International Journal of Food Sciences and Nutrition found that hazelnut consumption can reduce inflammation and improve blood vessel health. Hazelnuts are especially high in monounsaturated fats, which help lower bad cholesterol and protect the heart. Their rich, nutty flavor is famous in spreads like Nutella, but hazelnuts are healthiest when eaten raw or dry-roasted. The antioxidants in hazelnuts can also help protect cells from aging and damage. For a sweet yet healthy treat, try them paired with dark chocolate.
6. Pecans: Antioxidant Superstars
Pecans are best known for their role in pies, but they’re incredibly healthy on their own. Just one ounce (about 19 halves) delivers more than 19 vitamins and minerals, including thiamin, zinc, and manganese. A 2023 study from Tufts University ranked pecans among the highest nuts for antioxidant content. The unique fats in pecans can help lower total and LDL cholesterol, making them beneficial for heart health. Pecans’ buttery flavor and soft texture are a hit in both sweet and savory dishes. While they are higher in calories and fat than some other nuts, their high antioxidant content makes them a smart choice in moderation. Some experts compare the antioxidant power of pecans to that of blueberries.
7. Brazil Nuts: Selenium Specialists
Brazil nuts are your go-to nut if you want to boost your selenium intake—a mineral essential for thyroid health and immune function. Just one Brazil nut contains more than 100% of your daily selenium needs, according to the USDA. In a 2023 clinical trial, people who ate two Brazil nuts a day showed significant improvements in antioxidant markers and reduced inflammation. Because they are so high in selenium, you don’t need to eat many—one or two a day is plenty. Brazil nuts are also a good source of healthy fats and magnesium. Their smooth, creamy texture makes them a satisfying snack. However, eating too many Brazil nuts can lead to selenium toxicity, so moderation is key.
8. Macadamia Nuts: Rich, But Calorie Dense
Macadamia nuts are famous for their creamy texture and rich, buttery flavor. They’re higher in fat than most other nuts—one ounce (about 10-12 nuts) has 21 grams of fat—but most of it is the healthy monounsaturated kind. According to a 2024 review in the journal Nutrients, regular macadamia consumption can help reduce LDL cholesterol and improve heart health. They’re also a source of thiamin and manganese, which support energy production in the body. Because they’re so calorie-dense, it’s easy to eat too many, so portion control is important. Macadamias are often used in baking, but they’re delicious on their own, too. Their mild, sweet flavor makes them a favorite in both sweet and savory dishes.
9. Peanuts: The Everyday Protein Boost (Technically a Legume!)
Peanuts are technically legumes, but they’re usually grouped with nuts due to their similar nutrition profile. They’re an affordable source of protein, with 7 grams per ounce. Peanuts are also high in niacin and folate, which support brain health and DNA repair. In 2023, a large study in the Journal of the American Medical Association linked peanut consumption to lower risk of heart disease and longer life. Peanuts are also rich in resveratrol, an antioxidant found in red wine. However, many peanut products are high in added salt, sugar, or unhealthy oils, so it’s best to choose dry-roasted or raw peanuts. Their familiar, nutty flavor makes them a staple in lunchboxes and pantries everywhere.
10. Pine Nuts: Small But Mighty
Pine nuts are tiny, but don’t let their size fool you—they’re packed with nutrients. One ounce (about 167 pine nuts) delivers 4 grams of protein and is a good source of vitamin K, magnesium, and zinc. Pine nuts also contain pinolenic acid, which may help reduce appetite, according to a 2023 nutrition study. Their delicate, buttery taste is a key ingredient in classic pesto, but they’re also delicious sprinkled on salads or roasted vegetables. Pine nuts are higher in omega-6 fatty acids, which can promote inflammation if eaten in excess, so it’s best to eat them in moderation. Because they’re more expensive and sometimes harder to find, many people eat them less often than other nuts. Their unique flavor and texture set them apart, making them a gourmet addition to many dishes.
