Botanically, a type of single-seeded fruit in which the pericarp enclosing the seed is a hard woody shell. In common usage the term is used loosely for any hard, oil-rich kernel. Of those commonly eaten, only hazel, filbert, and chestnut are strictly nuts. Walnuts, pecans, almonds, and coconuts are really drupes. Brazil nuts, pistachios, macadamias, and cashews are really seeds with a hard shell derived from the testa rather than the pericarp.

A variety of walnut known as Tetracarpidium conophorum is widely cultivated in several parts of Africa for its edible nuts. These nuts have been reported for their huge antioxidant, anti-obesity, and anti-depressant potentials, but remain underutilized due to their poor storage and preservation. This is why the nuts are mostly cooked and consumed a...
Almond (Prunus sp.) is produced in large amounts in the province of ChaharMahal and Bakhtiari, Iran. The effects of super absorbent polymers (SAPs, potassium acrylamide, KC3H5NO) singly, or in combination with phosphorus (P) and iron (Fe), on the growth and morphological properties of 20-year old almond orchards were tested in a two-year field expe...
Pecan is a major specialty crop produced in the United States.

Hull-less seed trait is preferred by nut and oil industries worldwide for snacking and oil extraction as it evades the expensive decorticating (dehulling) process. This seed trait is available in C. pepo only, which has small seed cavity, sensitive to various biotic and abiotic stresses, and restricted to temperate regions for cultivation. Contrari...
Iron deficiency is the most prevalent micronutrient deficiency globally and is a common diagnosis in adolescent females. Causal factors for this population include low dietary iron intake, iron bioavailability, increased iron requirements and excessive iron losses. Iron intakes of adolescent females were last analysed in the 2002 New Zealand Childr...
