General Information
NameWalnut
Scientific NameJuglans regia
DescriptionWalnut, Juglans regia, is the edible seed of a drupe native to Iran (Persia). The most common species of walnut are cultivated in China and the United States. Walnuts are culinarily considered a nut, with a brown color, rich, nutty taste, and a distinctive odor. They are rich in manganese and B vitamins, and have been found to contain antioxidants and anti-inflammatory components. Walnuts have been linked to improved cognition, and a reduced risk of mild cognitive impairment and Alzheimer's disease. The most notable chemical in walnuts is juglone (PMID: 33567903). Walnuts are used medicinally to treat various health conditions, and industrially as a source of walnut oil, used in salad dressings (PMID: 36369998). Peculiarly, walnuts are often toasted or candied to enhance their flavor. They can be eaten raw, or used in a variety of dishes such as walnut soup, walnut pie, brownies, and baklava.
