In botanical terms, a nut is a hard-shelled fruit that does not split open to release its seed. Nuts are a type of fruit consisting of a seed and a hard shell, which is often edible. These shells protect the seeds inside and are usually quite hard, providing protection from physical damage and predators. Nuts are an essential part of the diets of many animals, including humans, as they are a good source of nutrients, healthy fats, and proteins.Common examples of true nuts include acorns, chestnuts, and hazelnuts. However, in culinary terms, many other items that are not botanically classified as nuts are referred to as such. For instance, almonds, cashews, and peanuts are often called nuts, but they are technically seeds or legumes. Despite the botanical distinctions, these foods are popularly categorized as nuts due to their similar nutritional profiles and uses in cooking. Nuts are consumed in various forms, including raw, roasted, or ground into pastes like peanut butter, and they are used in a wide range of culinary applications around the world.
