Hazelnut Benefits: 20 Reasons to Add Hazelnuts to a Healthy Diet

A close-up view of fresh whole and shelled hazelnuts highlighting their health benefits.

Hazelnuts are small, round tree nuts with a naturally sweet, buttery flavor and satisfying crunch. They are especially popular in desserts, chocolate spreads, and baked goods, but plain hazelnuts can also be a nutritious addition to a balanced diet.

They provide healthy unsaturated fats, dietary fiber, vitamin E, magnesium, copper, manganese, and other nutrients. Like other nuts, hazelnuts are relatively calorie-dense, so portion size is important.

In this first part, we’ll look at hazelnut nutrition and the first 10 potential hazelnut benefits.

What Are Hazelnuts?

Hazelnuts are the edible seeds of hazel trees. They are sometimes called filberts and are widely used around the world.

They can be eaten:

  • Raw
  • Dry roasted
  • Chopped
  • Ground into flour
  • Made into nut butter
  • Added to oatmeal
  • Mixed into salads
  • Used in baked goods

Hazelnuts are also commonly paired with chocolate because their naturally creamy flavor complements cocoa.

For everyday eating, plain or lightly roasted hazelnuts are generally the simplest choices.


Hazelnut Nutrition Facts

A 1-ounce (28-gram) serving of raw hazelnuts provides approximately:

Exact values can vary depending on the variety and whether the nuts are raw, roasted, salted, or otherwise processed.

One of the standout nutrients in hazelnuts is vitamin E, an antioxidant vitamin that helps protect cells from oxidative damage.


1. Hazelnuts Are Rich in Healthy Unsaturated Fats

One of the major hazelnut benefits is their high concentration of unsaturated fats.

Hazelnuts contain mostly monounsaturated fat, similar to foods such as:

  • Avocados
  • Olive oil
  • Almonds
  • Macadamia nuts
  • Pecans

Replacing some foods high in saturated fat with foods containing unsaturated fats can be part of a heart-conscious dietary pattern.

However, hazelnuts are still calorie-dense, so eating a moderate portion is important.


2. Hazelnuts Are a Good Source of Vitamin E

Hazelnuts are particularly notable for their vitamin E content.

Vitamin E is a fat-soluble vitamin with antioxidant functions. It helps protect cells from oxidative stress and supports normal immune function.

A 1-ounce serving of hazelnuts provides a meaningful amount of vitamin E.

Other foods that provide vitamin E include:

  • Almonds
  • Sunflower seeds
  • Peanuts
  • Avocado
  • Spinach

Adding different vitamin-E-rich foods to your diet can help increase dietary variety.


3. Hazelnuts Provide Dietary Fiber

Hazelnuts provide approximately 2.8 grams of fiber per ounce.

Dietary fiber contributes to normal digestive function and can be an important component of a healthy eating pattern.

Fiber-rich foods include:

  • Fruits
  • Vegetables
  • Beans
  • Lentils
  • Whole grains
  • Seeds
  • Nuts

Hazelnuts can contribute to your overall fiber intake, although they shouldn’t be your only source.

Manganese is an essential trace mineral involved in:

  • Normal energy metabolism
  • Bone formation
  • Protection of cells from oxidative stress
  • Normal connective tissue formation
  • Enzyme activity

A varied diet can provide manganese from nuts, seeds, whole grains, legumes, and other plant foods.


7. Hazelnuts Contain Antioxidant Compounds

Hazelnuts contain vitamin E and naturally occurring plant compounds that contribute to antioxidant activity.

Antioxidants help protect cells from oxidative stress.

However, it’s important not to think of hazelnuts as a miracle antioxidant food.

A wide variety of plant foods can provide different beneficial compounds.

Try including:

  • Berries
  • Citrus fruits
  • Tomatoes
  • Leafy greens
  • Beans
  • Whole grains
  • Nuts
  • Seeds

Hazelnuts can be one part of this overall pattern.


8. Hazelnuts Can Fit Into a Heart-Healthy Diet

Hazelnuts contain mostly unsaturated fats along with fiber and several micronutrients.

These characteristics make them compatible with dietary patterns that emphasize heart-conscious foods.

For example, you could replace a highly processed snack with:

A moderate serving of hazelnuts + fresh fruit

rather than adding the nuts on top of an already calorie-dense diet.

Hazelnuts aren’t a treatment for heart disease, but they can contribute to an overall nutritious eating pattern.


9. Hazelnuts Can Be a Satisfying Snack

The combination of fat, fiber, protein, and crunchy texture can make hazelnuts a convenient snack.

Instead of eating directly from a large package, measure a portion into a bowl.

Simple combinations

Hazelnuts + apple

Hazelnuts + pear

Hazelnuts + berries

Hazelnuts + plain Greek yogurt

These combinations add variety and can make a snack more nutritionally balanced.


10. Hazelnuts Can Add Nutritional Variety to Your Diet

Different nuts have different nutritional profiles.

For example:

Hazelnuts

Notable for vitamin E, monounsaturated fats, manganese, and copper.

Almonds

Known for vitamin E, magnesium, protein, and fiber.

Walnuts

Particularly notable for plant-based ALA omega-3 fatty acids.

Brazil nuts

Exceptionally rich in selenium.

Macadamia nuts

Particularly rich in monounsaturated fats.

Pecans

Provide unsaturated fats and several minerals.

There’s no requirement to choose just one type.

Rotating different nuts and seeds can make your diet more varied and enjoyable.


Hazelnuts and Healthy Fats

Hazelnuts are especially rich in monounsaturated fats.

These fats are also found in:

  • Olive oil
  • Avocado
  • Almonds
  • Pistachios
  • Pecans
  • Macadamia nuts

The overall quality of your diet matters more than any individual food.

A useful strategy is to use foods such as nuts and seeds in place of snacks dominated by refined carbohydrates, added sugars, or less favorable fats.


Hazelnuts and Vitamin E

Vitamin E is one of the nutrients that makes hazelnuts particularly interesting.

It acts as an antioxidant and helps protect cells from oxidative damage.

Vitamin E is fat-soluble, which means dietary fat helps with its absorption.

Hazelnuts naturally combine vitamin E with healthy fats, making them a useful food source of this nutrient.

However, eating excessive amounts isn’t necessary.

A moderate serving is enough to contribute to your overall vitamin E intake.


Hazelnuts and Digestive Health

The fiber in hazelnuts contributes to normal digestive function.

For a higher-fiber snack, you could combine hazelnuts with fruit.

For example:

Apple + hazelnuts

provides fiber from both foods.

A balanced diet should also include other sources of fiber, such as:

  • Oats
  • Beans
  • Lentils
  • Vegetables
  • Fruits
  • Whole grains
  • Chia seeds

If your usual diet is low in fiber, increase fiber gradually and drink enough fluids.


Hazelnuts and Weight Management

Hazelnuts can be included in a weight-management diet, but portion control is important.

A 1-ounce serving provides approximately 178 calories.

This means a few large handfuls can add substantial calories.

The better strategy is to replace a less nutritious snack rather than simply adding hazelnuts to your existing diet.

Example

Instead of:

Cookies + sugary drink

try:

Hazelnuts + apple + water

The goal isn’t to make hazelnuts a weight-loss food. Instead, they’re a nutrient-dense food that can fit within appropriate calorie intake.


Simple Ways to Add Hazelnuts to Your Diet

Breakfast

Add chopped hazelnuts to:

  • Oatmeal
  • Overnight oats
  • Greek yogurt
  • Smoothie bowls

Lunch

Try them in:

  • Green salads
  • Grain bowls

Are Hazelnuts Good for You?

Yes. Hazelnuts can be a nutritious addition to a balanced diet.

Their main nutritional strengths include:

  • Unsaturated fats
  • Vitamin E
  • Fiber
  • Magnesium
  • Copper
  • Manganese
  • Plant compounds with antioxidant activity

But like other nuts, they’re calorie-dense.

The best approach is to enjoy them in moderate portions and combine them with a variety of fruits, vegetables, whole grains, legumes, and protein-rich foods.

11. Hazelnuts May Support Healthy Cholesterol Levels

Hazelnuts contain predominantly unsaturated fats, particularly monounsaturated fats.

Replacing some foods high in saturated fat with foods rich in unsaturated fats can support a heart-conscious dietary pattern.

For example, instead of regularly choosing a highly processed snack, you could choose:

A moderate portion of hazelnuts + fresh fruit

The benefit comes from the overall dietary replacement, rather than hazelnuts acting as a medicine.

If you have high cholesterol, continue following the dietary and medical recommendations provided by your healthcare professional.


12. Hazelnuts Can Support a Heart-Healthy Eating Pattern

Several characteristics make hazelnuts compatible with heart-conscious eating:

  • Unsaturated fats
  • Dietary fiber
  • Vitamin E
  • Magnesium
  • Plant compounds

A nutritious heart-focused diet can include:

  • Fruits
  • Vegetables
  • Whole grains
  • Beans and lentils
  • Fish
  • Nuts and seeds
  • Unsaturated oils

Hazelnuts can easily fit into this pattern.

However, they shouldn’t be considered a treatment or cure for cardiovascular disease.


13. Hazelnuts Can Fit Into Blood Sugar-Friendly Meals

Hazelnuts contain relatively little carbohydrate compared with many grain-based snacks.

They also provide fat, fiber, and protein.

Adding a small amount of nuts to a balanced meal can create a more varied nutrient combination.

For example:

Plain Greek yogurt + berries + chopped hazelnuts

or:

Oatmeal + cinnamon + berries + hazelnuts

These combinations provide carbohydrates along with protein, fiber, and fat.

Hazelnuts aren’t a treatment for diabetes, but they can be part of a balanced eating pattern.


14. Hazelnuts May Support Digestive Health

Hazelnuts provide dietary fiber, which contributes to normal digestive function.

Regularly eating a variety of fiber-rich foods can help you meet your dietary fiber needs.

Good choices include:

  • Fruits
  • Vegetables
  • Beans
  • Lentils
  • Oats
  • Whole grains
  • Seeds
  • Nuts

For an easy high-fiber combination, try:

Apple + hazelnuts

The apple contributes additional fiber while the hazelnuts provide healthy fats and minerals.


15. Hazelnuts Provide Nutrients Involved in Energy Metabolism

Hazelnuts provide several nutrients involved in normal metabolic processes.

For example, magnesium contributes to normal energy metabolism, while copper and manganese participate in various enzyme functions.

This doesn’t mean hazelnuts provide an instant energy boost.

Instead, they provide dietary calories and nutrients that your body uses as part of normal metabolism.

For a balanced snack, combine them with a carbohydrate-rich food such as fruit.


16. Hazelnuts Can Be Useful for Active Lifestyles

People who exercise need enough calories and nutrients to support their activity.

Hazelnuts can be included in meals and snacks around workouts.

Before exercise

Try a small serving with fruit:

Banana + hazelnuts

After exercise

Combine hazelnuts with protein and carbohydrates:

Greek yogurt + berries + chopped hazelnuts

or:

Oatmeal + banana + hazelnuts + Greek yogurt

Because hazelnuts contain a lot of fat, very large portions immediately before intense exercise may feel heavy for some people.


17. Hazelnuts Provide Nutrients That Support Normal Brain Function

Hazelnuts provide nutrients such as:

  • Vitamin E
  • Magnesium
  • Copper
  • Healthy unsaturated fats

These nutrients contribute to normal physiological processes, including nervous-system function.

However, it’s important not to overstate the evidence.

Eating hazelnuts doesn’t guarantee:

  • Better memory
  • Higher intelligence
  • Protection from dementia
  • Prevention of neurological disease

Instead, hazelnuts can be one component of an overall nutritious dietary pattern.


18. Hazelnuts Provide Nutrients Relevant to Skin Health

Hazelnuts are particularly known for their vitamin E content.

Vitamin E has antioxidant functions and helps protect cells from oxidative stress.

Hazelnuts also provide healthy fats and several minerals.

However, eating hazelnuts isn’t a guaranteed treatment for:

  • Acne
  • Wrinkles
  • Dry skin
  • Skin aging

Healthy skin depends on many factors, including:

  • Overall nutrition
  • Sun exposure
  • Sleep
  • Hydration
  • Genetics
  • Skincare
  • General health

A nutrient-rich diet can support normal body functions, but no single food can transform your skin overnight.


19. Hazelnuts Provide Nutrients Important for Normal Bone Function

Hazelnuts provide minerals such as:

  • Magnesium
  • Manganese
  • Copper
  • Phosphorus

These nutrients contribute to normal physiological functions associated with bones and connective tissues.

However, maintaining strong bones requires more than nuts.

A balanced diet should also provide:

  • Calcium
  • Vitamin D
  • Protein
  • Vitamin K
  • Magnesium
  • Phosphorus

Regular physical activity, especially weight-bearing exercise, is also important for bone health.


20. Hazelnuts Can Replace Less Nutritious Snack Foods

One practical way to use hazelnuts is as a replacement for highly processed snacks.

For example:

Instead of:

  • Candy
  • Cookies
  • Sugary pastries
  • Highly processed snack foods

Try:

A measured portion of hazelnuts + fresh fruit

This doesn’t mean you can never eat desserts or other treats.

The goal is simply to make nutrient-dense foods a regular part of your diet.


Hazelnuts and Weight Loss

Hazelnuts can be included in a weight-loss diet, but they aren’t a fat-burning food.

A 1-ounce serving contains approximately 178 calories.

Therefore, eating several handfuls can quickly increase your calorie intake.

Better strategy

Use hazelnuts as a replacement.

Cookies → hazelnuts + apple

Candy → hazelnuts + berries

Sugary snack → Greek yogurt + hazelnuts

This approach can make it easier to control total calorie intake while improving nutritional quality.


Hazelnuts and Heart Health

Hazelnuts contain mostly unsaturated fats and provide fiber, vitamin E, magnesium, and other nutrients.

A heart-conscious meal could look like:

Grilled fish + vegetables + whole grains + a small amount of chopped hazelnuts

The goal is to build an overall healthy dietary pattern rather than relying on one food.


Hazelnuts and Blood Sugar

Hazelnuts are relatively low in carbohydrates and provide fat, fiber, and some protein.

This makes them a useful ingredient in balanced meals.

For example:

Oats + berries + Greek yogurt + hazelnuts

is nutritionally different from eating a sugary pastry alone.

However, individual blood-glucose responses vary, and people with diabetes should follow their personalized medical and nutrition guidance.

How Many Hazelnuts Should You Eat a Day?

A common serving size for nuts is about 1 ounce (28 grams).

For hazelnuts, that works out to roughly 18–21 whole nuts, depending on their size.

However, you don’t necessarily need to eat a full serving every day.

Your ideal amount depends on:

  • Your overall calorie needs
  • Activity level
  • Weight-management goals
  • The rest of your diet
  • Other nuts and seeds you consume

Because hazelnuts are calorie-dense, measuring a portion can help prevent accidentally eating several servings.

Simple tip

Instead of eating directly from a large bag, put your desired portion into a small bowl.


How Many Calories Are in Hazelnuts?

A 1-ounce (28-gram) serving of hazelnuts contains approximately 178 calories.

It provides roughly:

  • 4.2 grams protein
  • 17.2 grams fat

Instead of candy:

Greek yogurt + berries + chopped hazelnuts

Instead of a sugary snack:

Pear + hazelnuts

This allows you to enjoy their nutrients without unnecessarily increasing your total calorie intake.


Are Hazelnuts Good for a Low-Carb or Keto Diet?

Hazelnuts contain relatively few carbohydrates compared with many grain-based snacks.

They also provide:

  • Fat
  • Fiber
  • Some protein
  • Magnesium
  • Vitamin E
  • Manganese

For this reason, they can fit into many low-carbohydrate eating patterns.

However, they’re still calorie-dense.

If you’re following a specific therapeutic or medically prescribed diet, follow the recommendations provided by your healthcare professional.


Raw vs. Roasted Hazelnuts

Both raw and roasted hazelnuts can be nutritious.

The main thing to watch is what is added during processing.

Can You Eat Too Many Hazelnuts?

Yes.

Even nutritious foods can become excessive when consumed in very large amounts.

Eating several handfuls of hazelnuts can add a substantial number of calories.

Some people may also experience digestive discomfort from consuming large amounts.

Possible symptoms include:

  • Bloating
  • Gas
  • Stomach discomfort

A moderate serving is generally more practical.


Can Hazelnuts Cause Digestive Problems?

Hazelnuts contain dietary fiber and fat.

For most people, moderate amounts are well tolerated.

However, eating a large quantity at once may cause digestive discomfort, particularly if your usual diet is low in fiber.

If you’re increasing your intake, start with a smaller portion and gradually increase your overall dietary fiber from different foods.


How to Store Hazelnuts

Hazelnuts contain natural oils that can become rancid if exposed to heat, air, or light for extended periods.

For short-term storage

Keep them in:

  • An airtight container
