Cashews are among the most popular nuts in the world, valued not only for their delicious creamy flavor but also for their impressive nutritional profile. Often found in snacks, desserts, and main dishes, this kidney-shaped nut offers benefits ranging from heart health to improved immunity and better bone strength. However, like any powerful food, cashews come with considerations and potential side effects when consumed excessively.
This guide explores everything you need to know about cashews, including nutrition facts, science-backed health benefits, types, risks, dosage, and best ways to consume and store them.
What is Cashew?
Cashew is the edible kidney-shaped seed of the cashew tree (Anacardium occidentale), a tropical evergreen that originated in Brazil but is now widely cultivated in India, Vietnam, Africa, and Southeast Asia. Unlike most nuts, cashews grow externally on the cashew apple, a false fruit. The seed is encased in a toxic shell containing urushiol, a resin that can cause skin irritation. Therefore, cashews are always processed and roasted before becoming safe for consumption.
Cashews fall under the category of tree nuts and are used in numerous food preparations including nut butter, milk, cheese substitutes, sweets, gravies, desserts, and snacks. They are particularly appreciated in plant-based diets because of their healthy fats, protein content, and versatility in creating dairy alternatives.
