What it is

Walnuts are the edible seeds of trees belonging to the Juglans genus, most commonly the Persian or English walnut. They grow inside a hard shell, which is removed to reveal the wrinkled, two-lobed kernel.

Why it's used

Manufacturers add walnuts to foods for their distinct flavor, crunchy texture, and nutritional benefits. They are frequently found in baked goods like cakes, cookies, and muffins, as well as in snack mixes, cereals, and salads.

Health notes

Walnuts are considered a whole food and are generally recognized as safe (GRAS) for consumption. They are a good source of healthy fats, protein, and dietary fiber, and are often included in dietary recommendations. Regulatory bodies like JECFA and EFSA do not typically evaluate whole foods like walnuts for an acceptable daily intake (ADI), as they are not food additives.

Allergen info

Walnuts are a tree nut, which is one of the nine major food allergens identified by the FDA.
