treenut

A tree nut is the edible seed of a tree or shrub that is usually enclosed in a hard shell. In culinary use, tree nuts are consumed as snacks or ingredients and are valued for flavor, crunch, and nutrient density. Botanically, many foods commonly called nuts are seeds of fruits or capsules rather than true botanical nuts.

Examples include almonds, Brazil nuts, cashews, chestnuts, hazelnuts, macadamias, pecans, pistachios, and walnuts. While chestnuts are true nuts, others such as almonds and cashews are seeds of drupes. This distinction is mainly of botanical interest; in cooking and nutrition, they are treated as nuts.

Nutritionally, tree nuts are energy-dense and rich in fats (primarily heart-healthy unsaturated fats), protein, fiber, and micronutrients such as vitamin E and magnesium. They are commonly included in diets for flavor and satiety, and their regular consumption has been linked to various health benefits when part of an overall balanced diet.

Allergies: Tree nut allergy is among the more common and potentially severe food allergies. Reactions can vary in intensity, and cross-contact or cross-reactivity with other tree nuts is a concern for sensitive individuals. Proper labeling and avoidance are important for those affected.

Production and use: Tree nuts are grown in temperate climates. Major producers include the United States (notably California), Turkey, India, Iran, and Vietnam. They are widely used as snacks, in baked goods and confectionery, and processed into oils or nut milks, contributing to diverse culinary applications. Storage in a cool, dry place helps preserve freshness.
