Walnuts are the edible seeds of trees in the Juglans genus, most commonly the Persian or English walnut (Juglans regia). They are encased in a hard shell that is typically removed before consumption. Walnuts are highly valued for their distinctive taste and numerous health benefits. They are rich in omega-3 fatty acids, antioxidants, vitamins, and minerals, making them a popular choice for a healthy diet.

Walnuts are used in a variety of culinary applications. In baking, they add crunch and flavour to cookies, cakes, and breads. In cooking, they are incorporated into salads, pasta dishes, and sauces. Additionally, walnuts can be eaten raw, roasted, or as a topping for cereals and yoghurt. Their versatility makes them a favourite ingredient in many cuisines worldwide.

Treatment and Risks

Walnuts are generally considered safe and healthy for most people when consumed in moderation. However, they are a common allergen and can cause severe allergic reactions in some individuals. Symptoms of a walnut allergy can include hives, swelling, difficulty breathing, and anaphylaxis. People with nut allergies should avoid walnuts and products containing them.

Walnuts are also high in calories and fats, albeit healthy fats. Consuming them in large quantities can contribute to weight gain if not balanced with physical activity and other dietary considerations. Additionally, their rich oil content means they can go rancid if not stored properly; it is best to keep walnuts in a cool, dry place or refrigerate them to extend their shelf life.
