A walnut is the nut of any tree of the genus Juglans, particularly the Persian or English walnut, Juglans regia. A walnut is the edible seed of a drupe, and thus not a true botanical nut. It is commonly consumed as a nut.
Walnuts provide healthy fats, fiber, vitamins and minerals — and that’s just the beginning of how they may support your health.
Walnuts are rich in antioxidants and healthy fats. They may reduce heart disease and cancer risk, as well as improve brain function and possibly slow the progression of Alzheimer’s disease.
Walnuts are very healthy, but some people are allergic and must avoid them. Phytic acid may impair mineral absorption, though this is usually of no concern to people who eat a balanced diet.
Walnuts are one of the richest dietary sources of antioxidants. These include ellagic acid, ellagitannins, catechin, and melatonin.
