Pistachio nuts (Pistacia vera)
Pistachio nuts grow in very dry areas in poor soil, and they have been grown for centuries in the Mediterranean region, and are the nuts of choice in the Middle Eastern countries. Pistachio nuts are delicious, and they are excellent food value, being a good source of fibre, proteins with a good blend of essential amino acids, vitamins and minerals.76 The amino acid tryptophan is, however, in short supply, and in order to obtain maximum protein value it would be good to combine pistachios with other sources of this amino acid, such as seeds, some legumes, particularly soya beans, or cashew nuts. Pistachios are a good source of the minerals calcium, potassium and iron and they have a high vitamin A content. Moreover, they are nutrient-dense and offer an excellent balance of calories for concentrated nutrition. Pistachios can be milled, used in desserts, breads or savoury products and will be an asset in any kitchen.
