Cashew nuts are kidney-shaped seeds that are commonly consumed as a snack or used in cooking and baking. Cashew nuts are native to northeastern Brazil but are now grown in various tropical regions around the world, including India, Vietnam, Nigeria, and Ivory Coast They are nutrient-dense, containing good amounts of healthy fats, protein, and various vitamins and minerals. However, they are also calorie-dense, so portion control is important. Consuming cashew nuts in moderation may contribute to heart health due to their healthy fat content (monounsaturated and polyunsaturated fats). They also provide essential nutrients like magnesium, phosphorus, and zinc. Cashew nuts can be enjoyed roasted and salted as a snack, used in cooking (such as in stir-fries or curries), or ground into a creamy paste (cashew butter) used in vegan cooking as a dairy substitute. Cashew nuts are harvested from cashew apples, which are not commonly consumed themselves but can be used to make beverages or jams. The nuts are processed to remove the toxic shell and are then roasted, salted, or used in various culinary preparations Some individuals may have allergies to cashew nuts, which can cause severe reactions. Cross-reactivity with other nuts is also possible, Cashew farming can have positive impacts on rural economies but can also face challenges related to labor conditions and environmental sustainability, particularly concerning water usage and chemical inputs.
