Pecan nuts (Carya illinoensis)
Pecan nuts belong to the family Juglandaceae, to which also the walnut belongs. Pecans are
native to the southern states of the USA and to Mexico. Like hazel nuts, pecan nuts do not contain high concentrations of essential amino acids, and their total protein content is also quite low. Their fat content is, however, high and they contain a good balance of minerals and vitamins, including vitamin A. The oil in pecan nuts is also rich in essential oils.71 Pecan nuts make great snacks, they can also be used in breakfast foods and be used in baking.
