Nutritional Breakdown: Hazelnuts vs. Macadamia Nuts
Both hazelnuts and macadamia nuts provide impressive health benefits, though their specific nutritional advantages vary. Hazelnuts are richer in certain vitamins, minerals, and protein, while macadamia nuts have higher levels of monounsaturated fats and are lower in carbohydrates. Understanding these differences allows for a more personalized approach to nutrition. All nutritional comparisons are based on 100g of raw, unsalted nuts.
Comparing Healthy Fats, Calories, and Protein
Macadamia nuts are known for their high-fat content, but it consists primarily of heart-healthy monounsaturated fat, which helps to lower LDL ('bad') cholesterol. With about 718 calories per 100g, they are one of the most calorie-dense nuts. Hazelnuts contain fewer calories (around 628 kcal per 100g) and less total fat, but still have a high proportion of healthy monounsaturated fats. Hazelnuts stand out for their protein content, providing almost double the amount per serving compared to macadamias, which contributes to greater satiety and muscle maintenance.
A Vitamin and Mineral Face-off
Hazelnuts shine in their antioxidant profile. They contain dramatically higher levels of Vitamin E—an antioxidant that protects cells from oxidative damage—with some sources indicating levels up to 27 times greater than macadamia nuts. Hazelnuts are also packed with:
- Vitamins: B vitamins like folate and vitamin B6, crucial for brain function.
- Minerals: A wealth of manganese, copper, and potassium, with potassium levels twice that of macadamias.
Macadamia nuts contain a good amount of thiamine (vitamin B1) and manganese. However, macadamias notably lack vitamins A and K and have fewer vitamins and minerals compared to hazelnuts.
Glycemic Impact and Antioxidant Power
Macadamia nuts have a lower glycemic index (10) and fewer net carbs than hazelnuts, making them a slightly more favorable option for low-carb diets such as keto. Both are considered low-glycemic, so their impact on blood sugar levels is minimal.
Both nuts offer unique antioxidant benefits. Hazelnuts contain high levels of phenolic compounds and vitamin E, while macadamias provide tocotrienols and flavonoids. This diverse antioxidant activity supports overall health and lowers the risk of chronic diseases like cancer and heart disease.

Making Your Choice
Deciding which nut is healthier comes down to personal health goals. For those prioritizing a nutrient-dense snack rich in antioxidants, vitamins, and protein, hazelnuts are the winner. Their high Vitamin E content provides exceptional protection against oxidative stress, benefiting skin and brain health. If the focus is on a low-carb diet or a calorie-dense snack for sustained energy, macadamia nuts are the superior choice due to their high healthy fat content and very low glycemic index. Enjoying both nuts as part of a varied diet is the best strategy, leveraging the unique strengths of each to promote overall wellness.
A word on portion size: Nuts should be consumed in moderation due to their high-calorie density. A standard serving is about one ounce (28 grams), or roughly a small handful. This ensures you reap their nutritional rewards without overindulging.
Conclusion
The comparison of hazelnuts or macadamia nuts highlights their distinct nutritional profiles. Hazelnuts offer a wider array of vitamins, particularly a dose of antioxidant Vitamin E, and more protein. Macadamia nuts are unmatched for their low-carb count and high monounsaturated fat content, perfect for specific low-glycemic dietary needs. A handful of each ensures a broad spectrum of heart-healthy fats, vital vitamins, and essential minerals, leading to a balanced and nutritious diet overall.
