The peanut, or groundnut (Arachis hypogaea) is a species in the legume family Fabaceae native to South America. It is an annual herbaceous plant growing to 30 to 50 cm (1 to 1 1/2 feet) tall. The leaves are opposite, pinnate with four leaflets (two opposite pairs; no terminal leaflet), each leaflet 1 to 7 cm (1/3 to 2.75 inches) long and 1 to 3 cm (1/3 to 1 inch) broad. The flowers are a typical peaflower in shape, 2 to 4 cm (3/4 to one and a half inches) across, yellow with reddish veining. After pollination, the fruit develops into a legume 3 to 7 cm (1 to 2 inches) long containing 1 to 3 (rarely 4) seeds, which forces its way underground to mature.



Although a nut in the culinary sense, in the botanical sense the fruit of the peanut is a woody, indehiscent legume or pod and not technically a nut.



Peanuts are also known as earthnuts, goobers, goober peas, pindas, jack nuts, pinders, manila nuts and monkey nuts (the last of these is often used to mean the entire pod, not just the seeds).

Peanuts are a rich source of proteins (roughly 30 grams per cup after roasting) and Monounsaturated fat. Recent research on peanuts and nuts in general has found anti-oxidants and other chemicals that may provide health benefits. [7] Peanuts are a significant source of resveratrol, a chemical studied for potential anti-aging effects.



Because peanuts are considered an incomplete protein, containing relatively low amounts of the essential amino acids Lysine, Cystine, and Methionine, it is advised to be sure that a diet or meal with peanuts as a staple also include complementary foods such as dairy or whole grain



Although many people enjoy foods made with peanuts, some people have severe allergic reactions. For people with peanut allergy, exposure can cause fatal anaphylactic shock. For these individuals, eating a single peanut or just breathing the dust from peanuts can cause a fatal reaction. An allergic reaction also can be triggered by eating foods that have been processed with machines that have previously processed peanuts, making avoiding such foods difficult.



A theory of the development of peanut allergy has to do with the way that peanuts are processed in North America versus other countries like China and India. Peanuts are widely eaten in China and India but peanut allergies are almost unheard of there. According to a 2003 study, roasting peanuts, as more commonly done in North America, causes the major peanut allergen Ara h2 to become a stronger inhibitor of the digestive enzyme trypsin, making it more resistant to digestion.[2] Additionally, this allergen has also been shown to protect Ara h1, another major peanut allergen, from digestion - a characteristic further enhanced by roasting.

a common leavening agent used in baked goods. Used for fireproofing, in baking powder, and as an antirheumaticalso used as a fire retardant and in fertilizers.

Dried coconut meat, called copra, is pressed and used to make coconut oil, which is used in commercial frying and as a component in many packaged goods such as candies, margarines, soap and cosmetics. Coconut oil-one of the few nonanimal saturated fats-is used widely in the manufacture of baked goods such as commercial cookies. Certain major manufacturers have replaced it with the more expensive unsaturated fats with an eye toward cholesterol consciousness.

Sugar produced from cornstarch; comprised of glucose (dextrose), maltose and higher sugars; 70 percent to 80 percent solids

Sugar based sweeteners are those such as that developed from corn starch. The development of the various types of corn syrups, maltodextrins, and high-fructose corn syrup from corn starch sources could be called one of the greatest changes in the sugar and sweetener industry over several centuries. In the late 1800s it was found that corn starch could be hydrolyzed and a sugar formed. It was not until the 1970s that it became commercially a major product bringing about changes in the food industry. Over-reliance in the food industry and over-indulgence by consumers of these processed sugers, particularly high fructose corn syrup, has most likly contributed to obesity in many western countries.



These sweeteners are processed and refined using a series of separation, and grinding processes. Finally, the products are converted and fermented. From this processing a five classes of corn sweeteners are formed. This does not include the corn syrup conversion into high-fructose corn syrup.

Salt is one of the most ubiquitous food ingredients around. Those who think of salt only as something used to perk up flavor might wonder what could possibly give this ingredient the level of importance it has gained through the ages. In reality, there is much more to this crystalline cube than first meets the eye.



Besides enhancing taste, salt has several other functions in food products. It acts as an antimicrobial or microbiological control agent. It contributes to certain chemical reactions that create a wide variety of food characteristics.



Sometimes the terms "salt" and "sodium" are used interchangeably, but technically this is not correct. "Salt" is sodium chloride. By weight, it is 40 percent sodium and 60 percent chloride.

Most foods and tap water contain sodium and chloride. Sodium is an essential nutrient, a mineral that the body cannot manufacture itself.

Because of sodium's importance to your body, the excretory and nervous systems guard against under-consumption of salt, which is a threat to your body's nerves and muscles. Other ions such as calcium, magnesium, and potassium are also very important. Concentrations of these ions are held in narrow ranges by the kidney.



The association between eating salt and the risk of blood pressure increasing is difficult to quantify. Some people are sensitive to changes in salt intake whereas others can adjust so that blood pressure does not rise at all.



Americans typically consume 4,000-8,000 mg each day, well above their daily needs. A goal for moderation for all adults, (including pregnancy and lactation) is approximately 2,400 mg of sodium per day.
