Top 10 Nuts

Pistachio: The pistachio, a member of the cashew family, is a small tree originating from Central Asia and the Middle East. The tree produces seeds that are widely consumed as food. 

Cashew: The tree can grow as tall as 14 metres, but the dwarf cultivars, growing up to 6 m, prove more profitable, with earlier maturity and greater yields. 

Peanut:  It is widely grown in the tropics and subtropics, being important to both small and large commercial producers.

Pecan: The tree is cultivated for its seed in the southern United States, primarily in Georgia, New Mexico, Texas, and Mexico, which produces nearly half of the world total.

Almond: The almond is a species of tree native to Iran and surrounding countries, including the Levant. The almond is also the name of the edible and widely cultivated seed of this tree.

Walnut:  Although culinarily considered a "nut" and used as such, it is not a true botanical nut. After full ripening, the shell is discarded and the kernel is eaten. 

Hazelnut: The hazelnut is the fruit of the hazel tree and therefore includes any of the nuts deriving from species of the genus Corylus, especially the nuts of the species Corylus avellana. 

Brazil Nut: The Brazil nut is a South American tree in the family Lecythidaceae, and it is also the name of the tree's commercially harvested edible seeds.

Chestnut: True chestnuts are deciduous trees and shrubs in the genus Castanea, in the beech family Fagaceae. They are native to temperate regions of the Northern Hemisphere. 

Macadamia: They are indigenous to Australia, native to northeastern New South Wales and central and southeastern Queensland specifically.
