Identifying Types of Nuts from Photos and Descriptions
Nuts make for nutritious and delicious snacks as well as useful ingredients in recipes. With so many varieties to choose from, it helps to be able to identify nuts visually and by their descriptions. Here is a guide to recognizing various types of nuts from photos and learning their distinguishing characteristics.
Almonds
Almonds are one of the most popular nut varieties. They have an elongated oval shape and light brown outer skin. The edible inside kernel is pale beige in color. Almonds have a sweet, mild, nutty flavor. They are native to the Middle East but also grow successfully in California.
Walnuts
Walnuts are named for their brain-like appearance. They have a wrinkly brown exterior shell. Inside is a lobe-shaped kernel with two halves separated by a septum. Walnut meat is slightly tan and tastes sweeter than other nuts. Walnuts grow on trees primarily in California.
Pecans
Pecans have a smooth brown oval shell that hides the delicious seed inside. The pecan kernel has a beige color tinged with red-brown streaks. Pecans offer a rich, buttery flavor. They grow in temperate climates of North America and Mexico.
Pistachios
Pistachio shells are hard and tan-colored with shades of red and green. They contain small greenish-yellow seeds with a distinctive vertical split. When roasted, pistachios have a sweet, nutty taste. They thrive in hot, dry areas and became popular in the Middle East.
Cashews
Unlike most nuts, cashews grow attached to the bottom of a cashew apple. The tropical cashew nut is contained in a double shell with toxic residue. Safe, edible cashews are curvy with a gray-brown hue. Their flavor is sweet and almost buttery. Cashews originate from northeastern Brazil.
Chestnuts
Chestnuts have a spiny brown outer husk and hard inner shell. The edible chestnut is small and round with a dark beige color. Chestnuts are starchier than most nuts with a mildly sweet flavor. They grow on large trees found in temperate regions of the Northern Hemisphere.
Hazelnuts
Hazelnuts, also called filberts, are encased in a smooth brown outer husk. The inner seed has a tan, oval shape with white flecks. Hazelnuts are very flavorful with a rich, nutty taste. The trees produce dangling clusters of nuts and thrive in temperate climates.
Macadamia Nuts
Macadamia nuts grow inside a green spiny hull on tropical evergreen trees. The incredibly hard shell protects the white kernel with high fat content. Macadamia nuts taste creamy and sweet with hints of butterscotch and vanilla. They are native to Australia but also grow in Hawaii.
Pine Nuts
Pine nuts come from the seeds of pinecones grown on pine trees. They have a tan, elongated teardrop shape and a soft texture. Pine nuts offer a pungent, piney flavor that works well in pesto and salads. They are foraged from wild trees around the world.
Brazil Nuts
Brazil nuts grow in large orange pods that hold up to 25 seeds each. The Brazilian seeds have a triangular shape and smooth brown surface. They provide an extremely crunchy texture with a mild, creamy taste. Brazil nuts are harvested wild from the Amazon rainforest region.
Peanuts
Peanuts are actually legumes, not true nuts. They grow underground rather than on trees. The tan, wrinkled shell hides 1-4 edible brown-red-skin peanut seeds. Peanuts have an elongated oval look and nutty, earthy flavor. They thrive in warm climates like the southern United States.
Health Benefits of Different Nut Varieties
Beyond their divergent appearances and flavors, most nuts also provide unique health advantages. Here are some of the top benefits of popular nut types:
Almonds
Almonds are filled with vitamin E, an antioxidant that protects cells from damage. They also provide calcium, magnesium, and potassium for bone health. The fiber in almonds helps lower cholesterol.
Walnuts
Walnuts contain omega-3 fatty acids called alpha-linolenic acid that support heart health. They are also a good plant-based source of protein and fiber.
Pecans
Pecans offer antioxidants, vitamin E, fiber, and unsaturated fats that may help lower bad LDL cholesterol when eaten in moderation.
Pistachios
The high levels of lutein and zeaxanthin in pistachios promote eye health. Their anti-inflammatory compounds may lower risk of certain cancers and heart disease.
Cashews
Cashews provide zinc, magnesium, and good fats. Combined with their creamy texture, cashews make for a dairy substitute in vegan diets.
Chestnuts
Unlike most nuts, chestnuts contain very little fat and lots of carbohydrates. They offer an alternative source of nutrients for low-fat, low-carb, or vegan eating plans.
Hazelnuts
Also called filberts, hazelnuts contain amino acids for building muscle along with vitamin E, folate, and healthy fats.
Macadamia Nuts
Macadamias have the highest fat content of any nut, mostly heart-healthy monounsaturated fat. They offer antioxidants along with vitamins B and E.
Pine Nuts
Pine nuts provide protein, fiber, and phytochemicals like pinolenic acid that may suppress appetite and help with weight management goals.
Brazil Nuts
Brazil nuts are an excellent source of the antioxidant mineral selenium, which may prevent cellular damage and support immune function.
Peanuts
Peanuts contain genistein, a compound with antioxidant effects that may inhibit growth of cancer cells while protecting heart health.
