Cashews are often misclassified due to their unique properties and duality as both a nut and a fruit. While they are generally referred to as nuts in culinary terms, understanding the true nature of cashews opens up a fascinating world of botany and nutrition. This article will explore what type of food cashews are, delving into their origins, nutritional benefits, culinary uses, and environmental impact.
What Exactly Is a Cashew?
Cashews originate from the tropical regions of South America but are now grown in various parts of the world, including Africa and Asia. The cashew tree, scientifically known as Anacardium occidentale, produces a cashew apple and a cashew nut.
The Cashew Apple
The cashew apple is the fruit of the cashew tree. It is a unique, pear-shaped structure that can be consumed fresh or made into beverages. However, its most well-known use is in the production of cashew nut products. Despite being juicy and flavorful, the cashew apple is often overlooked in favor of the nut.
Key characteristics of the cashew apple include:
- Bright yellow to red color
- Soft, juicy texture
- A sweet, slightly tart flavor
Although the cashew apple itself is edible, it is not commonly exported due to its short shelf life.
The Cashew Nut
The real star of the show is the cashew nut, which is found at the bottom of the cashew apple. The nut itself is encased in a hard shell that contains an oil called urushiol, which can cause skin irritation. Therefore, cashew nuts are processed to remove this toxic shell and make them safe for consumption.
Cashew nuts are nutrient-dense foods, offering:
- High amounts of healthy fats, particularly monounsaturated fats
- Protein content sufficient for a substantial snack
Upon roasting and processing, cashew nuts acquire a delightful crunch and a flavor that complements both savory and sweet dishes.

What is a cashew: a nut or a fruit?
The cashew is technically classified as a seed, but it is often referred to as both a nut and a fruit. Cashews grow from the cashew apple, which is the fleshy, edible part of the tree, while the actual cashew seed is what we commonly consume as a nut. In botanical terms, a nut is a hard-shelled fruit that does not open up to release its seeds, while the cashew does not fit this description perfectly.
The cashew apple itself is also edible and can be used to make juices, jams, and even alcoholic beverages. However, the seed we think of as the cashew nut is found outside the fruit, attached to the bottom of the cashew apple. This unique structure contributes to the confusion about whether the cashew should be categorized primarily as a nut or a fruit.
Where do cashews grow?
Cashew trees are native to northeastern Brazil but are now cultivated in many tropical regions around the world. Significant production areas include countries in West Africa, Southeast Asia, and India. The trees thrive in well-drained sandy soils and require a warm, tropical climate for optimal growth, making these regions ideal for cultivation.
Cashew trees are not only valued for their nuts but also for the cashew apples, which can be harvested in tandem with the seeds. The process of harvesting involves picking ripe cashew apples, which are then processed to extract the nuts. This harvest method emphasizes the tree’s unique fruit-nut relationship, showcasing its versatility in culinary uses.
Are cashews healthy for you?
Yes, cashews are considered healthy and nutritious. They are rich in healthy fats, proteins, vitamins, and minerals, making them a valuable addition to a balanced diet. Cashews contain monounsaturated fats, which are beneficial for heart health, and they are a great source of essential nutrients like magnesium, zinc, and iron. These nutrients play vital roles in various bodily functions, such as immune support and energy production.
However, like all nuts, cashews are calorie-dense, so portion control is important. A moderate consumption of cashews can be part of a healthy diet and may even help with weight management and reducing the risk of chronic diseases. It’s also important to consider any allergies, as some people may experience adverse reactions to nuts, including cashews.
How are cashews harvested?
The harvest of cashews is a labor-intensive process. Once the cashew apples ripen, fruit pickers collect them from the cashew trees. The nuts are still attached to the apples during this process, and they must be carefully separated after harvesting. Each apple typically bears a single cashew, which is why cashew production can be time-consuming.
After harvesting, the cashew nuts must undergo a drying process to ensure they are ready for consumption. They are often roasted or steamed to remove the toxic resin found in the shells. Once processed, cashew nuts can be sold raw, roasted, or flavored, while the leftover cashew apples can be utilized in various culinary products or consumed as a fresh fruit.
What are the different varieties of cashews?
There are several varieties of cashews, each differing in shape, size, and flavor. The most common type is the ‘W180’ cashew, which refers to the number of whole nuts per kilogram. Other varieties include ‘W210’ and ‘W240’, which are larger but occur in fewer quantities per kilogram. The quality and size of the nuts often dictate their market value and use in culinary applications.
Beyond these commercial grading systems, there are also numerous cultivars adapted to different growing conditions. These varieties can display varying levels of sweetness, oil content, and shell thickness. The wide range of varieties allows manufacturers and consumers to enjoy various textures and flavors in their cashew products, from peanut butter-like spreads to whole roasted snacks.
Can you eat cashew apples?
Yes, cashew apples are indeed edible and are enjoyed in various cultures. They have a sweet and slightly tangy flavor, making them a delightful treat on their own or as ingredients in beverages, jams, and sauces. In some regions, cashew apples are pressed to produce juice, which is consumed fresh or fermented into alcohol, showcasing their versatility.
However, due to their perishable nature, cashew apples are often not widely available in markets outside of producing regions. Moreover, the fruit is highly perishable and has a short shelf life, so it is typically consumed immediately after harvest. Those lucky enough to be near cashew trees can enjoy the unique flavor and nutritional benefits of cashew apples alongside the more commonly recognized cashew nuts.
