19 Types of Nuts: An A to Z Guide

Last Updated on April 7, 2022 by Michael Joseph

There are many different types of nuts, and they all have their own characteristics.

Nuts are among the most beneficial foods, and they provide a broad range of essential nutrients.

This guide features all the common nut varieties and provides an overview of their characteristics and nutritional data.

Unless otherwise stated, all nutritional values are courtesy of the USDA’s FoodData Central Nutrition Database.

1) Acorns

Two Acorns.

Although it is a little-known fact, acorns can be an edible and nutritious nut.

Acorns have a long history of use as a source of food, and they were once a staple around the world.

In fact, 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, perhaps due to the lengthy preparation they need, 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 (28.35 gram) serving of acorns provides (3):

  • Calories: 110 kcal
  • Carbohydrates: 11.6 g
  • Fat: 6.78 g
  • Saturated: 0.88 g
  • Monounsaturated: 4.28 g
  • Polyunsaturated: 1.3 g
  • Omega-3: 0 g
  • Omega-6: 1.3 g
  • Protein: 1.74 g

Quick Facts

  • Acorns are a true tree nut.
  • An ounce (28g) serving of acorns is equivalent to approximately nine acorns.
  • Acorns are not exceptionally high in vitamins or minerals, but they offer a moderate source of manganese: approximately 17% of the daily value (3, 4).

3) Baru Nuts

A Pile of Baru Nuts.

Baru nuts are a lesser-known nut variety, but they have grown in popularity over recent years.

Like several other foods that we know as “nuts,” baru nuts are not a true tree nut.

Instead, they are similar to peanuts in that they are botanically a legume (6).

The nuts mainly grow in Brazil and offer a good range of nutritional benefits, a striking visual appearance, and taste good.

The USDA has a listing for baru nuts that provides their nutritional values per 3-tbsp (30-gram) serving. However, to keep things consistent, the values have been calculated and adjusted for an ounce-sized serving (7):

  • Calories: 151 kcal
  • Carbohydrates: 8.5 g
  • Fiber: 3.8 g
  • Sugars: 0.9 g
  • Fat: 11.3 g
  • Saturated: 2.4 g
  • Protein: 6.6 g

Quick Facts

  • Botanically, baru nuts are legume seeds rather than tree nuts.
  • Baru nuts are moderately high in all three macronutrients: carbohydrates, fat, and protein.

See this guide to baru nuts and their nutritional benefits for more information

4) Black Walnuts

Black Walnuts.

While most of us only know the word ‘walnut,’ it is worth knowing that there are two common types of walnut.

One of these is the English walnut, which is most prevalent and has the scientific name ‘Juglans regia’ (8).

The second type is the black walnut, which has the scientific name ‘Juglans nigra’ (9).

Although the two walnut varieties are similar nutritionally, English walnuts have a milder and more pleasant taste. For this reason, it is harder to find black walnuts, and the majority of walnut products use English walnuts as the ingredient.

Here are the nutritional values for an ounce (28.35g) serving of black walnuts (10):

  • Calories: 175 kcal
  • Carbohydrates: 2.72 g
  • Fiber: 1.93 g

18) Tiger Nuts

Tiger Nuts In a White Bowl.

Although they contain the word “nuts” in their name, and even though you may see them in the ‘nuts’ section, tiger nuts are not technically nuts.

Despite being relatively high in dietary fat, tiger nuts are small tubers, and they are more closely related to foods like sweet potatoes (37).

That said, people consume tiger nuts in a way similar to other 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.

How To Eat More Nuts

Here is a list of some ways to include more nuts into the diet:

  1. Replace existing ‘snacks’ in the diet with a handful of nuts
  2. Add a sprinkle of nuts into breakfast cereal
  3. Mix some nuts into a yogurt
  4. Make a trail mix of nuts, dried fruit, and dark chocolate pieces
  5. Blend some nuts into smoothies

Regarding the first of these points, it has been shown that replacing snacks such as potato chips with nuts can have benefits.

For instance, randomized controlled trials have demonstrated that adding nuts to the diet as a replacement for common snacks (such as pretzels) can (42, 43, 44):

  • Improve satiety levels (the feeling of being satisfied after eating and not feeling hungry)
  • Lead to potential weight loss
  • Improve markers of cardiovascular health

Make Homemade Nut Flours

Another way to incorporate more nuts could be to use nut flours rather than white flour.

Options such as almond flour are very popular and nutrient-rich, and they make food taste good.

Interestingly, making nut flours at home is relatively straightforward; all you need are the nuts of choice and a good quality blender.

It is important not to blend the nuts for too long for those who wish to try making a nut flour at home.

Once the nuts have been blended into a flour-like texture, further blending will release all their fat content, making the mixture sticky.

Generally speaking, it only needs 10 seconds of blending to get the right texture. However, this can vary depending on the specific nuts (and the quantity), so use personal judgment.

Are There Any Downsides To Eating Nuts?

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 an affordable and convenient food source.

However, as with anything, there can be some potential downsides.

Allergies

On the negative side, nut allergies are quite common, and allergic reactions to nuts can sometimes be severe (42, 43).

Here are some valuable guides to nut allergies for further information:

High In Calories

Nuts contain a large number of calories, and they are one of the most energy-dense foods.

While they are a healthy and nutrient-rich option, care is needed with portion size.

A typical serving of nuts is widely considered to be one ounce (28.35g), which is about a small handful.

Some Packaged Nuts Are Quite Salty

Some nuts are packaged and ready salted.

There is nothing wrong with consuming some salted nuts for those who like the taste. However, it is just something to be aware of, particularly for individuals carefully monitoring their salt intake.

Key Point: Similar to all foods, nuts can potentially have downsides, depending on how (and by who) they are eaten. That said, for most people, they are a beneficial food to include in the diet.

Common Questions About Nuts

If this guide didn’t adequately cover everything, here are some common questions people have about nuts.

Are nuts a good source of protein?

Nuts can be a good source of protein, depending on the specific nut. However, some options, such as acorns, chestnuts, macadamia nuts, and tiger nuts, only contain low protein.

Are nuts a whole food?
