Most seeds come from fruit that naturally free themselves from the shell, but this is not the case in nuts such as hazelnuts, chestnuts, and acorns, which have hard shell walls and originate from a compound ovary. The general and original usage of the term is less restrictive, and many nuts (in the culinary sense), such as almonds, pistachios, and Brazil nuts, are not nuts in a botanical sense. Common usage of the term often refers to any hard-walled, edible kernel as a nut. Nuts are an energy-dense and nutrient-rich food source.

Botanically, a nut is a fruit with a woody pericarp developing from a syncarpous gynoecium. True nuts include, for example, chestnut, hazelnut and filbert. Culinarily, the term 'nut' is used much more widely, and includes examples of drupes (such as pecans and almonds) or seeds (such as pine nuts and peanuts).

Also widely known as nuts are dry drupes, which include pecans, almonds, macadamia (Macadamia integrifolia), candlenut (Aleurites moluccanus) and the water caltrop (Trapa bicornis). A drupe is an indehiscent fruit that has an outer fleshy part consisting of the exocarp, or skin, and mesocarp, or flesh, which surround a single pit or stone, the endocarp with a seed (kernel) inside. In a dry drupe, the outer parts dry up and the remaining husk is part of the ovary wall or pericarp, and the hard inner wall surrounding the seed represents the inner part of the pericarp.

Walnuts and hickories (Juglandaceae) have fruit that are difficult to classify. They are considered to be nuts under some definitions but are also referred to as drupaceous nuts.

In common use, a "tree nut" is, as the name implies, any nut coming from a tree. This most often comes up regarding food allergies; a person may be allergic specifically to peanuts (which are not tree nuts but legumes), whereas others may be allergic to the wider range of nuts that grow on trees.

The sweet potato arrived in Europe with the Columbian exchange. It is recorded, for example, in Elinor Fettiplace's Receipt Book, compiled in England in 1604.

Nuts are eaten by humans and wildlife. Because nuts generally have a high oil content, they are a significant energy source. Many seeds are edible by humans and used in cooking, eaten raw, sprouted, or roasted as a snack food, ground to make nut butters, or pressed for oil that is used in cooking and cosmetics.

Nuts used for food are a common source of food allergens. Reactions can range from mild symptoms to severe ones, a condition known as anaphylaxis, which can be life-threatening. The reaction is due to the release of histamine by the body in response to an allergen in the nuts, causing skin and other possible reactions. Many experts suggest that a person with an allergy to peanuts should avoid eating tree nuts, and vice versa.
