Pistachio nuts

Pistachio nuts are the edible seeds of the *Pistacia vera* tree, native to Central Asia and the Middle East. The nuts are typically harvested when ripe, then shelled and often roasted or salted before being consumed or used in food products.

Pistachios are used as a snack food, both salted and unsalted, and are a popular ingredient in confectionery, desserts, and savoury dishes. They add a distinct nutty flavour, a crunchy texture, and a vibrant green colour to foods like ice cream, cakes, pastries, and curries.

Pistachios are not a food additive and are considered a whole food. They are a source of protein, fibre, and various vitamins and minerals. Like other nuts, pistachios are energy-dense. The UK's Eatwell Guide includes nuts as part of a healthy diet, recommending them as a source of protein and fibre. Evidence suggests that regular consumption of nuts, as part of a balanced diet, may be associated with cardiovascular health benefits, though more research is ongoing.
