How Cashews are Just a Seed

Cashews are one of the most popular snacks worldwide, with more than 1 million metric tonnes sold yearly – the equivalent of 5 Empire State Buildings filled with cashews. But most people don't know where they come from. Although we typically refer to them as a "dry fruit" or a "nut", they are technically neither.

Cashews are seeds that grow from the bottom of the cashew apple, the fruit of the cashew tree. The cashew's unique growing style, appearing like a small "tail" hanging from the fruit, makes it distinct in the world of plant anatomy. The apple that comes attached to it is called an accessory fruit, the name given to fruits that don't contain the seed. The fruit has a very complex flavor that is hard to consume, typically ending up in juices or jams.

Eating a cashew is not as simple as grabbing one and getting the seed. Raw cashews contain urushiol, a chemical that can cause skin reactions similar to poison ivy. Proper processing, which includes steaming or roasting, eliminates this risk, making them safe to consume. Originally from South America, the nut became an integral part of Indian cuisine after being introduced there by the Portuguese.

Beyond being a delicious snack, cashews are rich in vitamins, minerals, and antioxidants, including magnesium, vitamin E, and selenium. Regular consumption has been linked to improved heart health, weight management, and a reduced risk of chronic diseases. But when looking at the end product, nobody would expect that it comes from an apple with this little bean-shaped thing attached to it.
