Both hazelnuts and peanuts are staples in healthy eating, but they come from different plant families and offer varied nutritional profiles. Peanuts are technically legumes, growing underground, whereas hazelnuts are true tree nuts. Understanding these differences and their respective health benefits is key to deciding which is the better choice for your diet.
Nutritional Showdown: Hazelnuts vs. Peanuts
To determine the winner in the battle of hazelnuts versus peanuts, we must break down their core nutritional components. While both are high in fat and calories, the composition of these macronutrients, along with their vitamin and mineral content, varies significantly.
Protein Power
When it comes to protein, peanuts are the clear winner. For every 100 grams, peanuts offer approximately 25.8 grams of protein, a substantial amount for a plant-based food. This makes them a fantastic option for individuals looking to increase their protein intake, support muscle repair, and feel full for longer. Hazelnuts, by comparison, contain less protein, around 14.95 grams per 100 grams, making them a less dense source.
The Fat Factor
Both nuts are high in fat, but the quantity and composition differ. Hazelnuts contain more fat overall, with about 60.75 grams per 100 grams compared to peanuts' 49.24 grams. The good news is that the majority of this fat in both is heart-healthy monounsaturated and polyunsaturated fats. Hazelnuts are particularly noted for their high oleic acid content, a monounsaturated fat that may benefit insulin sensitivity.
Vitamin and Mineral Profiles
The vitamin and mineral contest is where the real nuance lies. Hazelnuts stand out for their high content of Vitamin E and manganese. A single ounce can provide over a quarter of the daily value for Vitamin E, a potent antioxidant. They also offer significant amounts of folate, magnesium, and copper. Peanuts, on the other hand, are a stellar source of B vitamins, including niacin (B3) and folate (B9). Folate is especially crucial during pregnancy, supporting fetal development. Peanuts also offer more magnesium and phosphorus compared to hazelnuts.
Fiber and Antioxidants
Dietary fiber is important for digestive health, and both nuts provide it. Hazelnuts generally contain more fiber per 100 grams than peanuts. Regarding antioxidants, both are packed with beneficial plant compounds. However, much of the antioxidant content in hazelnuts, particularly proanthocyanidins, is concentrated in the skin, so eating them whole is best. Peanuts also contain powerful antioxidants, such as p-coumaric acid and resveratrol.

Health Benefits Breakdown
Heart Health
Both hazelnuts and peanuts are excellent for cardiovascular health. Their high monounsaturated and polyunsaturated fat content helps to lower LDL ('bad') cholesterol. Studies have shown that both can improve lipid profiles and lower heart disease risk. The American Heart Association lists both as healthy choices for heart-conscious diets.
Weight Management
While both nuts are calorie-dense, their protein and fiber content promote a feeling of fullness, which can aid in appetite control and weight management. Studies have observed that regular, moderate nut consumption does not lead to weight gain and can actually support a healthy weight.
Specialized Benefits
For specific health concerns, one nut may hold an edge. Hazelnuts, rich in Vitamin E, contribute to skin and immune health and are associated with improved cognitive function due to their healthy fats and folate. The folate in peanuts, as previously mentioned, is especially beneficial during pregnancy. Peanuts also contain arginine, which can improve blood vessel health.
Who Should Choose Which? Making an Informed Decision
- For high protein: If your goal is to maximize your protein intake, especially as a plant-based eater, peanuts are the better option. Their higher protein content is more significant than that of hazelnuts.
- For enhanced fiber and antioxidants: If digestive health and antioxidant intake are your focus, hazelnuts offer a slightly higher fiber count and are a richer source of powerful antioxidants, especially when eaten with their skin.
- For heart health: Both are excellent choices for heart health due to their profile of healthy fats. The decision here may come down to personal taste preference or other nutritional needs.
- For boosting Vitamin E: If you want to increase your intake of Vitamin E, hazelnuts are a superior source compared to peanuts.
- For a lower fat content: While both are high in fat, peanuts have less overall fat per serving than hazelnuts.
- For budget-conscious shoppers: Peanuts are generally more affordable and widely available than hazelnuts.
Conclusion: No Single Winner, Just Different Strengths
Ultimately, neither hazelnuts nor peanuts are definitively healthier than the other; rather, they are both highly nutritious options with different strengths. The best choice depends on your specific dietary needs, health goals, and personal taste. Peanuts provide a more significant protein boost and are rich in B vitamins, while hazelnuts offer more Vitamin E, fiber, and heart-healthy monounsaturated fats. For most individuals, incorporating a variety of both nuts into a balanced diet is the best approach to gain the widest range of nutrients and health benefits. As always, choosing unsalted, unsweetened, and unprocessed versions is recommended to maximize the positive effects and minimize potential downsides.
