What is Walnut?
Walnuts are tree nuts from the Juglans genus, commonly found encased in a hard shell. They are cultivated as a food crop in temperate climates around the world. Walnuts are typically harvested in the fall, after which they are processed by removing the hard shell to reveal the edible nut meat.
Walnuts are used in a wide range of products due to their rich, nutty flavor and crunchy texture. They are often included in baked goods, cereals, and snack mixes for added nutritional value. Walnuts are rich in omega-3 fatty acids, antioxidants, and essential nutrients, which contribute to their perceived health benefits. Some studies suggest walnuts can support heart health and cognitive function, but more research is needed to fully understand these effects.
When you see walnuts on a label, it often indicates the product could be a source of beneficial nutrients, though consumers with tree nut allergies should be cautious.
