ALMONDS

Almonds:
Description:
The almond (Prunus dulcis, syn. Prunus amygdalus Batsch., Amygdalus communis L., Amygdalus dulcis Mill.), is a species of tree native to the Middle East and South Asia. "Almond" is also the name of the edible and widely cultivated seed of this tree. Within the genus Prunus, it is classified with the peach in the subgenus Amygdalus, distinguished from the other subgenera by the corrugated shell (endocarp) surrounding the seed.
The fruit of the almond is a drupe, consisting of an outer hull and a hard shell with the seed (which is not a true nut) inside. Shelling almonds refers to removing the shell to reveal the seed. Almonds are sold shelled (i.e., after the shells are removed), or unshelled (i.e., with the shells still attached). Blanched almonds are shelled almonds that have been treated with hot water to soften the seedcoat, which is then removed to reveal the white embryo.

History:
Harvesting of the almond crop at Qand-i Badam, India (16th century)
The almond is native to the Mediterranean climate region of the Middle East, eastward as far as the Indus. It was spread by humans in ancient times along the shores of the Mediterranean into northern Africa and southern Europe and more recently transported to other parts of the world, notably California, United States.

The wild form of domesticated almond grows in parts of the Levant; almonds must first have been taken into cultivation in this region. The fruit of the wild forms contains the glycoside amygdalin, "which becomes transformed into deadly prussic acid (hydrogen cyanide) after crushing, chewing, or any other injury to the seed."Almond is considered to be one of the earliest domesticated tree nuts. Wild almonds are bitter, its kernel produces deadly cyanide upon mechanical handling, and eating even a few dozen at one sitting can be fatal. Selection of the sweet type, from the many bitter type in wild, marked the beginning of almond domestication. How man selected the sweet type remains a mystery. It is unclear as to which wild ancestor of almond created the domesticated variety. Ladizinsky suggests the taxon Amygdalus fenzliana (Fritsch) Lipsky is the most likely wild ancestor of almond in part because it is native of Armenia and western Azerbaijan where almond was apparently domesticated.
While wild almond varieties are toxic, domesticated almonds are not; Jared Diamond argues that a common genetic mutation causes an absence of glycoside amygdalin, and this mutant was grown by early farmers, "at first unintentionally in the garbage heaps, and later intentionally in their orchards".  Zohary and Hopf believe that almonds were one of the earliest domesticated fruit trees due to "the ability of the grower to raise attractive almonds from seed. Thus, in spite of the fact that this plant does not lend itself to propagation from suckers or from cuttings, it could have been domesticated even before the introduction of grafting".Domesticated almonds appear in the Early Bronze Age (3000–2000 BC) such as the archaeological sites of Numeria (Jordan),  or possibly a little earlier. Another well-known archaeological example of the almond is the fruit found in Tutankhamun's tomb in Egypt (c. 1325 BC), probably imported from the Levant. Of the European countries that the Royal Botanic Garden Edinburgh reported as cultivating almonds, Germany  is the northernmost, though the domesticated form can be found as far north as Iceland.

Health benefits of Almonds:Almond nuts are rich in dietary fiber, vitamins, and minerals and packed with numerous health promoting phyto-chemicals; the kind of well-balanced food ensure protection against diseases and cancers.
These nuts are rich source of energy and nutrients. They are especially, rich in mono-unsaturated fatty acids like oleic and palmitoleic acids that help to lower LDL or "bad cholesterol" and increase HDL or "good cholesterol." Research studies suggest that Mediterranean diet, which is rich in monounsaturated fatty acids helps to prevent coronary artery disease and strokes by favoring healthy blood lipid profile.
The nuts are an excellent source of vitamin E; contain about 25 g per100 g (about 170% of RDA). Vitamin E is a powerful lipid soluble antioxidant, required for maintaining the integrity of cell membrane of mucus membranes and skin by protecting it from harmful oxygen free radicals.
Almonds are free in gluten and therefore, are a popular ingredient in the preparation of gluten free food formulas. Such formula preparations are in fact healthy alternatives in people with wheat food allergy and celiac disease.
These nuts are packed with many important B-complex groups of vitamins such as riboflavin, niacin, thiamin, pantothenic acid, vitamin B-6, and folates. These vitamins functions as co-factors for enzymes during cellular substrate metabolism.
They are also rich source of minerals like manganese, potassium, calcium, iron, magnesium, zinc, and selenium.
The sweet almond oil is obtained from the nuts is an excellent emollient; helps to keep skin well protected from dryness. It has also been used in cooking, and as “carrier or base oil” in traditional medicines in aromatherapy, in pharmaceutical and cosmetic industry.
Just a hand full of these nuts a day provides enough recommended levels of minerals, vitamins, and protein. Besides, almond oil extracted from the nuts has been used in as base or carrier oil in medicine, aromatherapy and in pharmaceuticals.
