Walnut

Walnuts are the edible seeds of trees belonging to the Juglandaceae family. They are native to the temperate regions of the Northern Hemisphere, with the English walnut (Juglans regia) being the most commonly cultivated. Walnuts are typically harvested in the autumn and can be consumed raw, roasted, or used in various culinary applications.

Walnuts are primarily used for their rich, slightly bitter flavour and crunchy texture. They are a popular ingredient in baked goods such as cakes, cookies, and pastries, and are also found in confectionery, salads, and savoury dishes. Their nutritional profile also makes them a valued component in snack mixes and as a topping for yogurts and cereals.

Walnuts are not a food additive and are not assigned an E-number. They are a source of beneficial nutrients, including omega-3 fatty acids, fibre, and antioxidants. Some research suggests that regular consumption of walnuts may contribute to cardiovascular health, as indicated by reviews published in peer-reviewed journals. The Food Standards Agency (FSA) and Food Standards Scotland (FSS) provide general dietary guidance, encouraging a balanced diet rich in fruits, vegetables, and whole grains, which would include nuts like walnuts.
