The cashew tree (Anacardium occidentale) is a tropical evergreen tree that produces the cashew seed and the cashew apple. It can grow as high as 14 m (46 ft), but the dwarf cashew, growing up to 6 m (20 ft), has proved more profitable, with earlier maturity and higher yields.
The species is originally native to northeastern Brazil. Portuguese colonists in Brazil began exporting cashew nuts as early as the 1550s. Major production of cashews occurs in Vietnam, Nigeria, India, and Ivory Coast.
The cashew nut, often simply called a cashew, is widely consumed. It is eaten on its own, used in recipes, or processed into cashew cheese or cashew butter. The shell of the cashew seed yields derivatives that can be used in many applications including lubricants, waterproofing, paints, and arms production, starting in World War II. The cashew apple is a light reddish to yellow fruit, whose pulp can be processed into a sweet, astringent fruit drink or distilled into liquor.
Its English name derives from the Portuguese name for the fruit of the cashew tree cajú (Portuguese pronunciation: [kaˈʒu]), which itself is derived from the Tupian word acajú, literally meaning “nut that produces itself”. The generic name “Anacardium” (derived from Greek ἀνά (aná), meaning “outside,” and καρδία (kardía), meaning “heart”, refers to the unusual location of the seed (the heart) outside of the fruit.
Culinary uses for cashew seeds in snacking and cooking are similar to those for all tree seeds called nuts.
Cashews are commonly used in Indian cuisine and Pakistani cuisine, whole for garnishing sweets or curries, or ground into a paste that forms a base of sauces for curries (e.g., korma), or some sweets (e.g., kaju barfi). It is also used in powdered form in the preparation of several Indian sweets and desserts. In Goan cuisine, both roasted and raw kernels are used whole for making curries and sweets. Cashews are also used in Thai and Chinese cuisines, generally in whole form. In the Philippines, cashew is a known product of Antipolo, and is eaten with suman. The province of Pampanga also has a sweet dessert called turrones de casuy, which is cashew marzipan wrapped in white wafers. In Indonesia, roasted and salted cashews are called kacang mete or kacang mede, while the cashew apple is called jambu monyet (translates in English to monkey rose apple).
In Mozambique, bolo polana is a cake prepared using powdered cashews and mashed potatoes as the main ingredients. This dessert is popular in South Africa.
In Brazil, the cashew fruit juice is popular. Brazilians value the fruit over the nut. In Panama, the cashew fruit is cooked with water and sugar for a prolonged time to make a sweet, brown, paste-like dessert called dulce de marañón, with marañón as a Spanish name for cashew.
In the 21st century, cashew cultivation increased in several African countries to meet the demands for manufacturing cashew milk, a plant milk alternative to dairy milk.
The shell of the cashew nut contains oil compounds which may cause contact dermatitis similar in severity to that of poison ivy, primarily resulting from the phenolic lipids, anacardic acid, and cardanol. Due to the possible dermatitis, cashews are typically not sold in the shell to consumers. Readily and inexpensively extracted from the waste shells, cardanol is under research for its potential applications in nanomaterials and biotechnology.
Cashew originated from Brazil, the South American tropics and cashew gradually dispersed to Africa, Asia, Australia. Today cashew has strewn in the boundary latitude 300 North and latitude 30.
Cashew can be grown in harsh and diverse climatic conditions. High heat-loving plant is sensitive to cold, tropical climate with a marked dry season is the perfect conditions to thrive tree.
According to FAO, nowadays, in the world, cashew is considered as a commercial product in 32 countries but there are only 10 tropical and subtropical countries where cashew trees grow well in the world today including: India, Vietnam , Brazil, Nigenia, Tanzania, Indonesia, Guinea Bissau, Cotolvore, Monzambique.
However, cashews are grown in popularity in southern Viet Nam, which is the most famous place in the world for the great reputation of the cashew. It has been grown as an official special crop and plays an significant role in the agricultural sector in some tropical and subtropical countries

Eating cashew nuts is very beneficial for our heart and keep our cardiovascular system healthy because of the presence of a good number of healthy dietary fats in it. These fats are essential for our body as they help in the proper absorption of fat-soluble vitamins like vitamin A, D, E and K. Other than this, the inclusion of other fats like monounsaturated fats(MUFA) and polyunsaturated fats (PUFA) also make cashew nuts beneficial for our heart.
Moderate consumption of cashew nuts helps in controlling cholesterol level as they reduce bad cholesterol level ( LDL cholesterol) and increase good cholesterol level (HDL cholesterol ). The presence of high level of LDL cholesterol can be a threat to our cardiovascular system and give rise to heart problems like heart attack, stroke, hardening of arteries (atherosclerosis ), etc.
The best way to minimize the risk of these cardiovascular problems is to reduce bad cholesterol and increase good cholesterol level. Studies have demonstrated that cashew nuts and other foods that are rich in unsaturated fats are very useful for this as they enhance the level of HDL cholesterol, reduces triglyceride levels and also helps in regulating blood pressure. High blood pressure is also a major cause of the cardiovascular problem but eating cashew nuts also helps in controlling blood pressure level under control and thus helps in keeping cardiovascular system healthy.

Antioxidants fights with the unstabilized ions of our body stabilize them and prevent them from damaging our body cells (including the immune system cells), and the zinc plays a vital role in making our system stronger against the microbial infections, helps in protein synthesis and quick healing of wounds.
The immune system of our body plays a very important role in keeping us healthy as it fights with the foreign pathogens that try to invade our body and harm us by spreading diseases.
