15 Types of Nuts: How Do They Compare?

Last Updated on

There are many different types of nuts.

Some of these are known as “true nuts,” and their pods do not contain separate seeds and fruit. True nuts include chestnuts, pecans, and hazelnuts.

Others are not botanically nuts, but we tend to use them similar to other nuts. For example, almonds (seeds) and peanuts (legumes) are not true nuts despite most people thinking they are.

Nuts are full of beneficial nutrients, and they are one of the best foods we can eat for our health.

This guide will cover some of the most popular types of nuts and provide an overview and comparison of their nutritional benefits.

All nutritional values are courtesy of the USDA’s FoodData Central Database.

1) Acorns

Two Acorns.

Perhaps surprisingly to some people, acorns are a reasonably nutritious nut.

Acorns have a long history of use as a source of food, and they were once a staple food around the world. Historical records show that acorns played an important role in human diets as early as 6000 BC (1).

However, acorns require special preparation methods—such as leaching—to reduce their high tannin content (2).

In current times, acorns are not as popular as they once were as a food source.

However, they still play a role in some cuisines. For example, acorn jelly and acorn noodles are popular Korean dishes.

An ounce (28-gram) serving of acorns provides (3):

  • Calories: 110 kcal
  • Carbohydrates: 11.6 g
  • Fat: 6.8 g
  • Saturated: 0.9 g
  • Monounsaturated: 4.3 g
  • Polyunsaturated: 1.3 g
  • Omega-3: 0 g
  • Omega-6: 1.3 g
  • Protein: 1.7 g

Acorns are not particularly high in vitamins or minerals, but they offer a moderate source of manganese: approximately 17% of the daily value.

2) Almonds

Almonds originated in the Middle East, and they were domesticated thousands of years ago.

The nuts are popular around the world in their whole form, and there are also many food products made from the nuts such as almond flour and almond milk.

Almonds are not a true nut, and they are botanically a seed.

Per ounce (28-gram) serving, almonds provide (4):

  • Calories: 162 kcal
  • Carbohydrates: 6.0 g
  • Fiber: 3.5 g
  • Sugars: 1.2 g
  • Fat: 14.0 g
  • Saturated: 1.1 g
  • Monounsaturated: 8.8 g
  • Polyunsaturated: 3.5 g
  • Omega-3: 0.01 g
  • Omega-6: 3.5 g
  • Protein: 5.9 g

Almonds are also an excellent source of vitamin E and manganese, offering 48% and 27%, respectively, of the daily value.

See this full guide to the nutritional properties of almonds for more information.

3) Brazil Nuts

Brazil nuts grow in South America throughout the Amazon rainforest.

As their name suggests, they are particularly prevalent in Brazil, in addition to countries such as Bolivia, Colombia, and Venezuela.

The nuts grow on a tree known as Bertholletia excelsa (otherwise known as the Brazil nut tree), which can grow to hundreds of meters in height (5).

Brazil nuts are the biggest out of all nut varieties, and they are the world’s biggest source of dietary selenium (6).

The nuts are popular in their whole form, and chocolate-coated Brazil nuts are also quite popular.

Nutritionally, Brazil nuts offer the following nutrients per ounce (28-gram) serving (7):

  • Calories: 187 kcal
  • Carbohydrates: 3.3 g
  • Fiber: 2.1 g
  • Sugars: 0.7 g

  • Monounsaturated: 6.8 g
  • Polyunsaturated: 6.9 g
  • Omega-3: 0.01 g
  • Omega-6: 6.9 g

Just one serving of Brazil nuts also provides 543 mg of selenium, which is equivalent to 987% of the daily value.

See this full guide to Brazil nuts for more information on their benefits.

4) Cashew Nuts

Pile of Cashew Nuts.


Cashews are a true tree nut, and global production centers around Asia and Africa, with Vietnam and India being the top exporters (8).

Compared to other nuts, cashews have a higher concentration of carbohydrates, and they are slightly lower in fat.

  • Manganese: 20% of the DV

See this guide for more on the nutritional benefits of cashews.

5) Chestnuts

Picture of Two Chestnuts - Shelled and Unshelled.

Chestnuts are different from other kinds of nuts in that they are predominantly a source of starchy carbohydrates.

The majority of chestnut production happens in five countries: China, Bolivia, Turkey, South Korea, and Italy (10).

Roasted chestnuts appear for sale in the winter, and they are one of the tastiest forms of any nut.

Although chestnuts are a true tree nut, their nutrition profile is unlike other types of nuts.

Turkey dominates worldwide production of hazelnuts, and the nation produces more than two-thirds of the global supply (12).

As one of the most popular types of nuts, hazelnuts are delicious and used in all sorts of food products. Among their many uses, hazelnuts are a favorite pairing with chocolate and coffee.

  • Copper: 54% of the DV

See this overview of the benefits of hazelnuts for further information.

7) Macadamia

Picture of macadamia nuts.

Macadamia nuts originate in Australia, and a lot of commercial production happens there too.

However, the majority of global production takes place in South Africa, which produced 52,412 tons of macadamia nuts in 2018 (14).

Macadamia nuts are arguably the tastiest type of nut, and they have a delicious buttery taste. On the downside, they are reasonably expensive, and they are one of the least nutrient-dense nuts.

A typical ounce (28-gram) serving offers (15):

  • Calories: 204 kcal
  • Carbohydrates: 3.9 g
  • Fiber: 2.4 g
  • Sugars: 1.3 g

8) Peanuts

Picture of peanuts.

Although they are technically a legume, peanuts are one of the most popular types of ‘nuts.’

These nuts are usually available either salted, dry-roasted, or in the form of peanut butter, which is an incredibly popular food product.

Due to the popularity of these nuts, global production stands at approximately 45 million tons per year. China produces more than double the amount of any other country (16).

Despite being a legume botanically, peanuts share many of the same nutritional characteristics as true tree nuts, such as their high fat content.

13) Sacha Inchi

Sacha Inchi (Inca Peanuts) In Their Shells and Unshelled Nuts.

Similar to almonds, sacha inchi are seeds rather than true nuts.

However, they are sold and marketed as nuts.

Sachi inchi nuts are also commonly referred to as ‘Inca peanuts.’

The Amazon rainforest is home to a significant amount of sacha inchi production. Colombia, Ecuador, and Peru are among the largest global producers (25).

Additionally, sacha inchi nuts are one of the most significant plant-based sources of omega-3. Approximately half of their polyunsaturated fat content is from alpha-linolenic acid; the form of omega-3 found in plant foods (27, 28).

This complete guide to sacha inchi nuts provides more information.

14) Tiger Nuts

Tiger Nuts In a White Bowl.

Although they contain the word “nuts” in their name, tiger nuts are not really nuts.

Despite being relatively high in dietary fat, tiger nuts are actually a small type of tuber, and they are more closely related to foods like sweet potatoes botanically (29).

That said, tiger nuts are consumed in a way similar to other true nuts.

On this note, they can be eaten alone, added to yogurt, used in trail mixes, and tiger nut flour is a popular choice for baking.

Based on research into the nutritional quality of tiger nuts, a typical ounce (28-gram serving) should offer the following nutritional values (30, 31):

  • Calories: 117 kcal
  • Carbohydrates: 12.3 g
  • Fiber: 2.5 g
  • Sugars: 3.7 g

Final Thoughts

Generally speaking, all nuts are relatively nutritious and offer protein, some healthy fats, and a good range of vitamins and minerals.

In addition to their nutritional value, most nuts are also reasonably affordable and convenient.

On the negative side, nut allergies are quite common, and allergic reactions to nuts can sometimes be severe (34, 35).

For everyone else, though, nuts are a tasty and healthy food choice.
