The almond is a species of tree native to mediterranean climate regions of the middle east, from Syria and Turkey to India and Pakistan, altough it has been introduced elsewhere. While the almond is often eaten on its own, raw or toasted, it is also a component of various dishes. Almonds are available in many forms, such as whole, sliced (flaked, slivered), and as flour. Almond pieces around 2-3 mm in size, called "nibs", are used for special purposes such as decoration. Almonds yield almond oil and can also be made into almond butter or almond milk. These products can be used in both sweet and savoury dishes. Almonds are a source of vitamin E, copper, magnesium and high quality protein. They also contain high levels of healthy unsaturated fatty acids along with high levels of bioactive molecules, which may help prevent cardiovascular disease.
