Habitat :Lablab purpureus grows  throughout the tropics, especially in Africa, India and Indonesia.It is a  traditional food plant in Africa,

Description:
Lablab bean is a twining vine with leaflets in threes and showy bright purple flowers and pods. In frostfree areas the vine becomes woody and can reach more than 30 ft (9 m) in length. In zones 9 and colder, the vine remains herbaceous and rarely exceeds 10 ft (3 m). The leaflets are purplish green, broad oval or triangular in shape and 3-6 in (7.6-15.2 cm) long. The flowers are pealike, a rich, brilliant purple and arranged in loose clusters on long stems that extend above the foliage. The pods are just as showy as the flowers. They are flat and curved, about 3 in (7.6 cm) long and bright purple. The beans inside are dark colored with a conspicuous white hilum, the elongate scar on the edge of the bean where it was attached to the inside of the pod.

Several cultivars have been selected including some with white flowers and pale green pods; some with red flowers; some with long, thin cylindrical pods; and some dwarf forms. Some cultivars are grown primarily for the pods, some for the seeds, and some for roots. Some are day length neutral and some flower mainly as day length shortens.

Uses:
It is often grown as forage  and as an ornamental plant. In addition, this plant is also cited as a medicinal plant and a poisonous plant.

In Maharashtra, a special spicy curry, known as vaala che birde , is often used during fasting festivals during Shravan month.

In the Telangana region of India, bean pods are cut into small pieces and cooked as spicy curry in Pongal festival season, along with bajra bread; it has been a very special delicacy for centuries.

In Hue, Vietnam, it is the main ingredient of the dish chè dau ván.

In Kenya, it is known as njahi, and is popular among the Kikuyu group. It is thought to encourage lactation and has historically been the main dish for breastfeeding mothers. Beans are boiled and mashed with ripe and/or semiripe bananas, giving the dish a sweet taste.

The leaves are used as greens, but have to be cooked like spinach and the water has to be discarded

Medicinal Uses:
Lablab purpureus is mild-and-lightly-warm-natured, tastes sweet.  It can tonify the spleen and stomach, relieve internal heat fever, relieve summer beat-and damp and remove dampness to stop diarrohea, etc.,  leukorrhea, with reddish discharge, infantile malnutrition and anti-cancer, etc.  The seeds are used to stimulate gastric activities, for vomiting and diarrhoea in acute gastro-enteritis, thirst in heat-stroke,  rheumatic arthritis, sunstroke, as an antidote against fish and vegetable poisoning and to treat colic and cholera.  The flowers are used to treat dysentery when there is pus and bloody stools, inflammation of the uterus and to increase menstrual flow.  Contraindicated in cases of intermittent fevers and chills, and in cold disorders.

Botanical Name : Cyclopia genistoides
Family: Fabaceae
Subfamily: Faboideae
Tribe: Podalyrieae
Genus: Cyclopia
Kingdom: Plantae
Order: Fabales

Common Name :Bush Tea,Honeybush tea, Heuningbos,kustee, coastal tea

Habitat :Cyclopia species (Family: Fabaceae), better known as honeybush, are endemic to the fynbos biome of the Western and Eastern Cape provinces of South Africa. It is adapted to the climate and soil in these areas and grow in nematode free, well drained, sandy to sandy loam soils with low pH, low phosphorus, generally occurring in sites with a relatively mild micro-climate.  In mountainous areas the populations are found on the cooler, wetter southern slopes.  Where there is a regular presence of mist, the populations are found on all slopes.

Description:
Cyclopia genistoides is a small, typical fynbos shrub, easy to miss when not in flower. A much-branched woody shrub with golden yellow stems, it grows to about one metre. The short needle-like leaves are arranged in threes along the branches, a typical feature of Cyclopia. When flowering in spring the same shrub can take your breath away with a bold display of bright yellow flowers.

Money beetles are attracted to the sweet smelling flowers at the tip of the branches. They are responsible for most of the pollination. The brown seeds are formed in small pods that turn brown. The pods dry and split open within a few weeks as the seed ripens.

Propagation & Cultivation:
Cyclopia genistoides can be propagated by seed or cuttings. The best time to sow seed is from summer to autumn. To select viable seeds throw the seed into a jug of water and remove any seeds that float to the surface. Before sowing the seeds need to be treated. First, the hard seed coat which protects the small seeds, needs to be damage to enable the uptake of moisture for germination. In nature this hard seed coat would slowly be damaged in the soil by micro-organisms and other factors. In the nursery the scarifying of the dry seed can be done with sulfuric acid. Proceed with caution to avoid the chemical coming into contact with one’s skin.. If only a small amount of seed is needed, an easier way to damage the seed coat is to lightly sand the seeds with sandpaper.

The seeds of cyclopias and many other fynbos plants are adapted to germinate after fire. Experiments have shown that it is the smoke of the fire which stimulates the germination of the seed. To get this same effect the seed can be treated with smoke extract, which is produced and sold at Kirstenbosch.The seed must be sown on a medium with good drainage and a low pH of 3.5 to 5. Germination usually takes place within two weeks. To prevent damping off, a fungicide should be used.

The young seedlings are potted up as soon as they are big enough to handle and grown on in the nursery before planting out. Many plants of the legume family, which include cyclopias, are often difficult to root from cuttings, but Cyclopia genistoides is an exception. Tip cuttings can be made using Seradix 2 as a rooting hormone.

Honeybush needs to be planted in full sun and well-drained soil. The plants are sensitive to severe frost. The plants grow fairly fast but start to look untidy after a few years if not regularly pruned or burned, which is what usually happens in nature. After fire old honeybush plants shoot out vigorously from the surviving roots,which act as a storage organ.

Medicinal Uses:
Often dried and drunk as tea in South Africa.  Also of great value to sufferers from kidney and liver disorders.  To make the tea the stems and leaves are chopped into small pieces, wet and then left in heaps where they ferment spontaneously, They may be heated in an oven to about 60C – 70 C to enhance the process. After sufficient fermentation, the tea is spread out in the sun to dry. After sifting, it is ready for use. Honeybush tea, with its own distinct sweet taste and aroma, is made like ordinary tea, except that simmering enhances the flavor. Drinking honeybush tea is said to promote good health, stimulate the appetite, and the milk flow of lactating mothers.

Honeybush tea is a herbal infusion and many health properties are associated with the regular consumption of the tea. It has very low tannin content and contains no caffeine. It is therefore especially valuable for children and patients with digestive and heart problems where stimulants and tannins should be avoided.

Research on Honeybush tea has only started recently in the 90’s and already great progress was made on testing and researching the medicinal values of this tea. De Nysschen et al found 1995 three major phenolic compounds in honeybush tealeaves: a xanthone c-glycoside, mangiferin and O-glycosides of hesperitin and isosakuranetin, two flavanones.

Honeybush tea is normally consumed with milk and sugar, but to appreciate the delicate sweet taste and flavor, no milk or sugar should be added. Descriptions of the flavor vary from that of hot apricot jam, floral, honey-like and dried fruit mix with the overall impression of sweetness. The tea has the added advantage that the cold infusion can also be used as iced tea and that it blends well with fruit juices. Honeybush tea is prepared by boiling about 4-6 g of the dried material (approximately 2-3 tablespoonfuls) per liter for 20 minutes.

Synonyms. : Faba vulgaris Moench, Faba bona Medik., Faba equina Medik.

Common Name :Broad Bean, Fava Bean, Field Bean, Bell Bean or Tic Bean

Habitat :Broad Bean is  native to north Africa and southwest Asia, and extensively cultivated elsewhere. A variety is provisionally recognized.

Does not occur in the wild. It was grown in ancient times (cultivated for 2-3 thousand years), but only by purposeful cultivation. In Russia, it has been cultivated since the 6th to 8th century. In the USSR, it was cultivated as basic fodder almost everywhere, but the cultivated area was not large (around 20 thousand hectares). The greatest areas of cultivation are in Byelorussia and Ukraine, the Baltic states, and the Altai region.

Description:
Annual plant. Taproot is strongly branched, penetrates to a depth of 80-150 cm. Colonies of nodule bacterium, which enrich soil with nitrogen, are formed on the roots. Stalk thick, strong, upright, bare or slightly pubescent, tetrahedral, hollow, 10-150 (200) cm tall, branching only at base. Leaves paripinnate, large, pulpy, without tendrils (the axil of leaf ends with soft cusp); with 1-4 pairs of leaflets, 4-8 x 2-4 cm, elliptical, glaucous-green (with a waxen bloom), bare; stipules up to 2 cm long, ovate-triangular, dentate, with nectaries. Peduncles 0.9-3 cm long. Flowers large, up to 3.5 cm long, 2-6 (12) per cluster. Calyx tubular, bare. Corolla white or pinkish with violet veins, spathes with a black maculae. Self-pollinator, but sometimes cross-pollinated. Fruit is a bean with 2-4-8 seeds. Beans very large, 5-10 (35) x 1.5-4 cm, oblate, cylindrical or oblong-cylindrical, pulpy, short pubescence, with bare sutures, green color when young, brown and black color when mature, coriaceous, on 1-4 in axil. Seeds 0.5 to 4 cm long, usually flat, oval, with lateral, pressed elliptical or linear scar, dark violet, red-brown, light yellow or green in color. The beans are differentiated by size: large seed grade (weight of 1000 seeds is 800-1300 g), middle seed grade (weight of 1000 seeds is 500-700 g) and small seed grade (weight of 1000 seeds is 200-450 g). Large seed grade is cultivated as a vegetable.

Cultivation:
Broad beans have a long tradition of cultivation in Old World agriculture, being among the most ancient plants in cultivation and also among the easiest to grow. It is believed that along with lentils, peas, and chickpeas, they became part of the eastern Mediterranean diet in around 6000 BC or earlier. They are still often grown as a cover crop to prevent erosion, because they can over-winter and because as a legume, they fix nitrogen in the soil. These commonly cultivated plants can be attacked by fungal diseases, such as rust (Uromyces viciae-fabae) and chocolate spot (Botrytis fabae). It is also attacked by the black bean aphid (Aphis fabae).

The broad bean has high hardiness cvs. This means it can withstand rough climates, and in this case, cold ones. Unlike most legumes, the broad bean can be grown in soils with high salinity. However, it does prefer to grow in rich loams.

In much of the Anglophone world, the name broad bean is used for the large-seeded cultivars grown for human food, while horse bean and field bean refer to cultivars with smaller, harder seeds (more like the wild species) used for animal feed, though their stronger flavour is preferred in some human food recipes, such as falafel. The term fava bean (from the Italian fava, meaning “broad bean”) is sometimes used in English speaking countries, however the term broad bean is the most common name in the UK.

Culnilary Uses;
Broad beans are eaten while still young and tender, enabling harvesting to begin as early as the middle of spring for plants started under glass or over-wintered in a protected location, but even the main crop sown in early spring will be ready from mid to late summer. Horse beans, left to mature fully, are usually harvested in the late autumn. The young leaves of the plant can also be eaten either raw or cooked like spinach.

The beans can be fried, causing the skin to split open, and then salted and/or spiced to produce a savory crunchy snack. These are popular in China, Colombia, Peru (habas saladas), Mexico (habas con chile) and Thailand (where their name means “open-mouth nut”).

Broad bean purée with wild chicory is a typical Puglian dish in Italy.

In the Sichuan cuisine of China, broad beans are combined with soybeans and chili peppers to produce a spicy fermented bean paste called doubanjiang.

In most Arab countries, the fava bean is used for a breakfast dish called ful medames.

Fava beans are common in Latin American cuisines as well. In central Mexico, mashed fava beans are a common filling for many corn flour-based antojito snacks such as tlacoyos. In Colombia they are most often used whole in vegetable soups. Dried and salted fava beans are a popular snack in many Latin countries.

In Portugal, a fava bean (usually referred to as fava in Portuguese) is included in the bolo-rei (king cake), a Christmas cake. Traditionally, the person who gets fava has to buy the cake the following year.

In the Netherlands, they are traditionally eaten with fresh savory and some melted butter. When rubbed the velvet insides of the pods are a folk remedy against warts.

Broad beans are widely cultivated in the Kech and Panjgur districts of Balochistan Province in Pakistan, and in the eastern province of Iran. In the Balochi language, they are called bakalaink, and baghalee in Persian.

Medicinal  uses:     
Broad beans are rich in tyramine, and thus should be avoided by those taking monoamine oxidase (MAO) inhibitors.

The ground dried beans have bee used to treat mouth sores. In New Mexico, a paste made of ground beans and hot water is applied to the chest and back as a treatment for pneumonia.

Raw broad beans contain the alkaloids vicine, isouramil and convicine, which can induce hemolytic anemia in patients with the hereditary condition glucose-6-phosphate dehydrogenase deficiency (G6PD). This potentially fatal condition is called “favism” after the fava bean.

Broad beans are rich in L-dopa, a substance used medically in the treatment of Parkinson’s disease. L-dopa is also a natriuretic agent, which might help in controlling hypertension.

Areas of origin of the bean correspond to malarial areas. There are epidemiological and in vitro studies which suggest that the hemolysis resulting from favism acts as protection from malaria, because certain species of malarial protozoa such as Plasmodium falcipacrum are very sensitive to oxidative damage due to deficiency of the glucose 6-phosphate dehydrogenase enzyme, which would otherwise protect from oxidative damage via production of glutathione reductase.

The seed testas contain condensed tannins of the proanthocyanidins type  that could have an inhibitory activity on enzymes

Medicinal Uses;
The ground dried beans have bee used to treat mouth sores. In New Mexico, a paste made of ground beans and hot water is applied to the chest and back as a treatment for pneumonia.

Other Uses;
*In ancient Greece and Rome, beans were used in voting; a white bean being used to cast a yes vote, and a black bean for no. Even today the word koukia  is used unofficially, referring to the votes.

*In Ubykh culture, throwing beans on the ground and interpreting the pattern in which they fall was a common method of divination (favomancy), and the word for “bean-thrower” in that language has become a generic term for seers and soothsayers in general.

*In Italy, broad beans are traditionally sown on November 2, All Souls Day. Small cakes made in the shape of broad beans (though not out of them) are known as fave dei morti or “beans of the dead”. According to tradition, Sicily once experienced a failure of all crops other than the beans; the beans kept the population from starvation, and thanks were given to Saint Joseph. Broad beans subsequently became traditional on Saint Joseph’s Day altars in many Italian communities. Some people carry a broad bean for good luck; some believe that if one carries a broad bean, one will never be without the essentials of life. In Rome, on the first of May, Roman families traditionally eat fresh fava beans with Pecorino Romano cheese during a daily excursion in the Campagna. In Northern Italy, on the contrary, fava beans are traditionally fed to animals and some people, especially the elderly, might frown on human consumption. But in Liguria, Northern Italy too, fava beans are loved like in Rome, and consumed fresh, alone or with fresh Pecorino Sardo or with local salami from Sant’Olcese. In some Central Italian regions was once popular and recently discovered again as a more fancy food the “bagiana” a soup of fresh or dried fava beans seasoned with onions and beet leaves stir fried, before being added to the soup, in olive oil and lard (or bacon or cured ham’s fat).

*In Portugal, a Christmas cake called Bolo Rei (“King cake”) is baked with a fava bean inside. Whoever eats the slice containing it, is supposed to buy next year’s cake.

*In ancient Greece and Rome, beans were used as a food for the dead, such as during the annual Lemuria festival.

*In some folk legends, such as in Estonia and the common Jack and the Beanstalk story, magical beans grow tall enough to bring the hero to the clouds.

*The Grimm Brothers collected a story in which a bean splits its sides laughing at the failure of others. Dreaming of a bean is sometimes said to be a sign of impending conflict, though others said that they caused bad dreams.

*Pliny claimed that they acted as a laxative.

*European folklore also claims that planting beans on Good Friday or during the night brings good luck.

Rhamnus purshiana (Cascara Sagrada)

[amazon_link asins=’B01IIOOD48,B075PTL19Q,B074WC7RJW,B00FK3WRR6,B007AJT1TA,B074S66ZTG’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’85b414b1-bebc-11e7-8df0-01a6a33c0cf3′]

Bnical Name :Rhamnus cathartica
Kingdom: Plantae
Division: Magnoliophyta
Class: Magnoliopsida
Order: Rosales
Family: Rhamnaceae
Genus: Rhamnus
Subgenus: Frangula

Synonyms : Cervispina cathartica (L.) Moench,  Frangula purshiana, Rhamnus purshianus

Common Name: Cascara Buckthorn, Cascara, Bearberry, and in the Chinook Jargon, Chittam or Chitticum; Common Buckthorn

Habitat: Cascara sagrada is native to  Europe, including Britain, from Scandanavia south and east to N. Africa and W. Asia.  It grows in fen peat, scrub, hedges, ash and oak woods, on calcareous often dry soils.
Parts Used:Dried aged bark

Description:

Cascara sagrada is a small deciduous tree that grows from 15-20 feet in height. It has pubescent stems covered with reddish-brown bark and often gray lichen. The tree bears dark green elliptic to oblong-ovate leaves with prominent veins and toothed margins. The leaves are rounded at the base and have somewhat hairy undersides. Short-stemmed clusters of small, greenish-white flowers grow from the upper leaf axils; they eventually produce black, pea-sized drupes that are poisonous.

CLICK & SEE THE PICTURES

The bark is brownish to silver-grey with light splotching. The leaves are deciduous, alternate, clustered near the ends of twigs; they are oval, 5–15 cm long and 2–5 cm broad with a 0.6–2 cm petiole, dark shiny green on top, fuzzy and paler green below. The flowers are tiny, 4–5 mm diameter, with five greenish yellow petals; the flowering season is brief, disappearing by early summer. The fruit is a berry 6–10 mm diameter, bright red at first, quickly maturing deep purple or black, and containing three seeds.

It grows in moist, acidic soils in the shady side of clearings or in the marginal forest understory, near the edges of mixed deciduous-coniferous forests. It typically grows as a second-generation tree after alders have colonized a barren plot of land.

Cultivation:
Succeeds in any reasonably good soil. Prefers a dry or moist calcareous soil in sun or light dappled shade. This species is hardy to at least -15°c. Plants regenerate well after cutting or burning but young plants are rather prone to frost damage when grown in an exposed position. Plants are resistant to cattle grazing but young plants can be damaged by rabbits. Plants have a very shallow root system. This species often bears the aecidospore stage of ‘crown rust’ of oats so it should not be grown near cereals. The species in this genus are notably resistant to honey fungus. A good bee plant and a main food plant for the brimstone butterfly. Dioecious. Male and female plants must be grown if seed is required.

Propagation :
Seed – best sown as soon as it is ripe in the autumn in a cold frame. Stored seed will require 1 – 2 months stratification at 5°c and should be sown as early in the year as possible in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle, and grow them on in the greenhouse or cold frame for their first winter. Plant them out in late spring or early summer of the following year. Cuttings of half-ripe wood, July/August in a frame. Cuttings of mature wood of the current year’s growth, autumn in a frame. Layering in early spring.

Medicinal Uses:Constipation, Colon Disorders, Liver Problems, Poor Digestion, Colitis, Hemorrhoids, Skin Problems.
The dried, aged bark of this tree has been used continually for at least 1,000 years by both native and immigrant Americans as a laxative natural medicine, commercially called “Cascara Sagrada“, but old timers call it “chitticum bark”.

Cascara is a very effective laxative, containing hydroxymethyl anthraquinones that cause peristalsis of the large intestine, emodin and other rhamnoid glycosides. It has been used as such by many First Nations groups. For example, Cascara bark tea was drunk as a laxative by Nuxalk, Coast Salish, Nuu-chah-hulth, and Kwakwakawakw, and a decoction of the inner bark and water was used as a remedy for dysentery. The bark is often aged before use so it will be less likely to cause nausea. First introduced to Europe in 1877, about 3 million pounds of the bark is harvested annually for use in commercial laxatives.  Squaxin used a Cascara infusion to wash sores–sometimes people chewed the bark and then spit it on sores. The bark has also been used to treat heart strain, internal strains, and biliousness. Skagit people burn the bark and mix the charcoal with grease to rub on swellings, and also have employed the bark in a green dye for mountain goat wool. Makah eat the fresh berries in July and August. Internally used for chronic constipation, colitis, digestive complaints, hemorrhoids, liver problems, and jaundice.  It is a medium-strength laxative and somewhat weaker than Rhubarb root and Senna leaf.   Externally used to deter nail biting.

Cascara Sagrada means “sacred bark” in Spanish. The much more pertinent name chitticum means “shit come” in Chinook Jargon; chittam comes from the Chinook Jargon phrase chittam stick = “laxative tree” which is similarly from the English word “shit”.

The bark is harvested mostly from wild trees; over-harvesting in the middle 1900s eliminated mature trees near many settled areas. Once stripped from the tree, the bark is aged for about 1 year to make its effect milder. Fresh cut, dried bark causes vomiting and violent diarrhea.

Short term side effects of Cascara Sagrada herb:
A medline search did not reveal any significant short term cascara sagrada side effects as long as it is not used for more than a week or two at a time without a break. It is best to avoid cascara sagrada if you have a chronic intestinal condition such as ulcerative colitis, or diverticular disease.

Long term cascara sagrada side effects:
When cascara sagrada or other anthraquinone containing plants are used for prolonged periods, potentially serious side effects can occur. These cascara sagrada side effects may include cramping in the abdomen and loss of body fluids. Dark pigmentation in the colon can occur and this is called melanosis coli.

Cascara Sagrada Research Update:
Colon cleansing regimens. A clinical study in 1200 patients.
Gastrointest Radiol. 1982;7(4):383-9
The purgative effect of bisacodyl, anthraquinone glycosides ( Cascara sagrada ), and sodium picosulfate, alone or in combination with a saline purge and a tap water enema, was studied in 1200 patients. The cleansing effect was scored with regard to retained fecal residue evident on double-contrast studies of the colon. The combination of a contact laxative and a saline purge produced good cleansing effect in 52%-80% of the patients. With an additional tap water enema given 1 hour before the colon examination, however, 96% of the colons were clean. The taste and the effects of the cleansing systems were tolerated favorably by more than 90% of the patients. However, 17% reported restriction in work capacity on the day of bowel cleansing.

Other Uses:
Dye; Hedge; Hedge; Wood.

A green dye is obtained from the immature fruit. Mixed with gum arabic and limewater, it makes a green pigment used in watercolour painting. Yellow, orange and brownish dyes can also be obtained. The colours are rich but fugitive. A yellow dye is obtained from the bark. It has been used to colour paper and maps. Often grown as an informal hedge, it is also amenable to trimming. Wood – hard, handsome with a marble-like grain. Used for small turnery.

Known Hazards: The fruit is purgative but not seriously poisonous. Other parts of the plant may also be poisonous. Adverse effects: Diarrhoea, weakness. Urine may turn dark yellow or red which is harmless. Possible body potassium loss if used for more than 10 consecutive days

Soybeans are native to east Asia, but 45 percent of the world’s soybean area, and 55 percent of production, is in the United States. The U.S. produced 75 million metric tons of soybeans in 2000, of which more than one-third was exported. Other leading producers are Brazil, Australia, Argentina, China, and India.

Description:
The soybean is an annual plant Soy varies in growth and habit. The height of the plant varies from less than 0.2 to 2.0 m (0.66 to 6.56 ft).

The pods, stems, and leaves are covered with fine brown or gray hairs. The leaves are trifoliolate, having three to four leaflets per leaf, and the leaflets are 6–15 cm (2.4–5.9 in) long and 2–7 cm (0.79–2.76 in) broad. The leaves fall before the seeds are mature. The inconspicuous, self-fertile flowers are borne in the axil of the leaf and are white, pink or purple.  The fruit is a hairy pod that grows in clusters of three to five, each pod is 3–8 cm long (1–3 in) and usually contains two to four (rarely more) seeds 5–11 mm in diameter.

Like some other crops of long domestication, the relationship of the modern soybean to wild-growing species can no longer be traced with any degree of certainty. It is a cultural variety (a cultigen) with a very large number of cultivars. However, it is known that the progenitor of the modern soybean was a vine-like plant that grew prone on the ground.

Soybeans occur in various sizes, and in many hull or seed coat colors, including black, brown, blue, yellow, green and mottled. The hull of the mature bean is hard, water-resistant, and protects the cotyledon and hypocotyl (or “germ”) from damage. If the seed coat is cracked, the seed will not germinate. The scar, visible on the seed coat, is called the hilum (colors include black, brown, buff, gray and yellow) and at one end of the hilum is the micropyle, or small opening in the seed coat which can allow the absorption of water for sprouting.

The genus Glycine Willd. is divided into two subgenera(species), Glycine and Soja. The subgenus Soja(Moench) includes the cultivated Soybean, G. max(L.)Merrill, and the wild soybean, G. soja Sieb.& Zucc. Both species are annual. The soybean grows only under cultivation while G. soja grows wild in China, Japan, Korea, Taiwan and Russia. Glycine soja is the wild ancestor of the soybean: the wild progenitor. At present, the subgenus Glycine consists of at least 16 wild perennial species: for example, Glycine canescens, and G. tomentella Hayata found in Australia and Papua New Guinea

Beans are classed as pulses whereas soybeans are classed as oilseeds. It is a versatile bean, having a diverse range of uses.

The English word soy is derived from the Japanese pronunciation of shōyu, the Japanese word for soy sauce; soya comes from the Dutch adaptation of the same word.

Physical characteristics:
Soybeans occur in various sizes, and in several hull or seed coat colors, including black, brown, blue, yellow, and mottled. The hull of the mature bean is hard, water resistant, and protects the cotyledon and hypocotyl (or “germ”) from damage. If the seed coat is cracked the seed will not germinate. The scar, visible on the seed coat, is called the hilum (colors include black, brown, buff, gray and yellow) and at one end of the hilum is the micropyle, or small opening in the seed coat which can allow the absorption of water.

Remarkably, seeds such as soybeans containing very high levels of protein can undergo desiccation yet survive and revive after water absorption. A. Carl Leopold, son of Aldo Leopold, began studying this capability at the Boyce Thompson Institute for Plant Research at Cornell University in the mid 1980s. He found soybeans and corn to have a range of soluble carbohydrates protecting the seed’s cell viability. Patents were awarded to him in the early 1990s on techniques for protecting “biological membranes” and proteins in the dry state. Compare to tardigrades.

Cultivation:
Soybeans are an important global crop, providing oil and protein. The bulk of the crop is solvent-extracted for vegetable oil and then defatted soy meal is used for animal feed. A small proportion of the crop is consumed directly by humans. Soybean products do appear in a large variety of processed foods.

Soybeans were a crucial crop in eastern Asia long before written records, and they remain a major crop in China, Japan, and Korea . Prior to fermented products such as soy sauce, tempeh, natto, and miso, soy was considered sacred for its use in crop rotation as a method of fixing nitrogen. The plants would be plowed under to clear the field for food crops.Soy was first introduced to Europe in the early 1700s and the United States in 1765, where it was first grown for hay. Benjamin Franklin wrote a letter in 1770 mentioning sending soybeans home from England. Soybeans did not become an important crop outside of Asia until about 1910. In America, soy was considered an industrial product only and not utilized as a food prior to the 1920s. Soy was introduced in Africa from China in the late 19th Century and is now widespread across the continent.

Cultivation is successful in climates with hot summers, with optimum growing conditions in mean temperatures of 20 °C to 30 °C (68°F to 86°F); temperatures of below 20 °C and over 40 °C (68 °F, 104 °F) retard growth significantly. They can grow in a wide range of soils, with optimum growth in moist alluvial soils with a good organic content. Soybeans, like most legumes, perform nitrogen fixation by establishing a symbiotic relationship with the bacterium Bradyrhizobium japonicum (syn. Rhizobium japonicum; Jordan 1982). However, for best results an inoculum of the correct strain of bacteria should be mixed with the soybean (or any legume) seed before planting. Modern crop cultivars generally reach a height of around 1 m (3 ft), and take 80 to 120 days from sowing to harvesting.

Chemical composition of the seed:
The oil and protein content together account for about 60% of dry soybeans by weight; protein at 40% and oil at 20%. The remainder consists of 35% carbohydrate and about 5% ash. Soybean cultivars comprise approximately 8% seed coat or hull, 90% cotyledons and 2% hypocotyl axis or germ.

The majority of soy protein is a relatively heat-stable storage protein. This heat stability enables soy food products requiring high temperature cooking, such as tofu, soymilk and textured vegetable protein (soy flour) to be made.

The principal soluble carbohydrates, saccharides, of mature soybeans are the disaccharide sucrose (range 2.5 to 8.2%), the trisaccharide raffinose (0.1 to 1.0%) composed of one sucrose molecule connected to one molecule of galactose, and the tetrasaccharide stachyose (1.4 to 4.1%) composed of one sucrpose connected to two molecules of galactose. While the oligosaccharides raffinose and stachyose protect the viability of the soybean seed from desiccation (see above section on physical characteristics) they are not digestible sugars and therefore contribute to flatulence and abdominal discomfort in humans and other monogastric animals; compare to the disaccharide trehalose. Undigested oligosaccharides are broken down in the intestine by native microbes producing gases such as carbon dioxide, hydrogen, nitrogen, methane, etc.

Since soluble soy carbohydrates are found mainly in the whey and are broken down during fermentation, soy concentrate, soy protein isolates, tofu, soy sauce, and sprouted soybeans are without flatus activity. On the other hand, there may be some beneficial effects to ingesting oligosaccharides such as raffinose and stachyose, namely, encouraging indigenous bifidobacteria in the colon against putrefactive bacteria.

The insoluble carbohydrates in soybeans consist of the complex polysaccharides cellulose, hemicellulose, and pectin. The majority of soybean carbohydrates can be classed as belonging to dietary fiber.

Genetic modification:
Soybeans are one of the “biotech food” crops that have been genetically modified, and GM soybeans are being used in an increasing number of products. In 1995 Monsanto introduced Roundup Ready (RR) soybeans that have had a copy of a gene from the bacterium, Agrobacterium sp. strain CP4, inserted into its genome by means of a gene gun, that allows the transgenic plant to survive being sprayed by this non-selective herbicide, Roundup. Glyphosate, the active ingredient in Roundup, kills conventional soybeans. The bacterial gene is EPSP (5-enolpyruvyl shikimic acid-3-phosphate) synthase. Soybeans also have a version of this gene, but the soybean version is sensitive to glyphosate, while the CP4 version is not.

RR soybeans allow a farmer to spray widely the herbicide Roundup and so to reduce tillage or even to sow the seed directly into an unplowed field, known as no-till farming or conservation tillage. No-till agriculture has many advantages, greatly reducing soil erosion and creating better wildlife habitat; it also saves fossil fuels and sequesters CO2, a greenhouse effect gas. It should be noted that RR soybeans simplify the process, but are not a requirement for no-till agriculture. Roundup may be sprayed on the field (and weeds) before the non-RR soybeans have emerged from the soil.

In 1997, about 8% of all soybeans cultivated for the commercial market in the United States were genetically modified. In 2006, the figure was 89%. As with other “Roundup Ready” crops, concern is expressed over damage to biodiversity.[17] However, the RR gene has been bred into so many different soybean cultivars that the genetic modification itself has not resulted in any decline of genetic diversity, as demonstrated by a study on genetic diversity

The ubiquitous use of such types of GM soybeans in the Americas has caused problems with exports to some regions. GM crops require extensive certification before they can be legally imported into the European Union, where there is extensive supplier and consumer reluctance to use GM products for consumer or animal use. Difficulties with coexistence and subsequent traces of cross-contamination of non-GM stocks have caused shipments to be rejected and have put a premium on non-GM soy
Uses:
Soybeans can be broadly classified as “vegetable” (garden) or field (oil) types. Vegetable types cook more easily, have a mild nutty flavor, better texture, are larger in size, higher in protein, and lower in oil than field types. Tofu and soymilk producers prefer the higher protein cultivars bred from vegetable soybeans originally brought to the United States in the late 1930s. The “garden” cultivars are generally not suitable for mechanical combine harvesting because they have a tendency for the pods to shatter on reaching maturity.

Among the legumes, the soybean, also classed as an oilseed, is pre-eminent for its high (38–45%) protein content as well as its high (20%) oil content. Soybeans are the leading agricultural export in the United States. The bulk of the soybean crop is grown for oil production, with the high-protein defatted and “toasted” soy meal used as livestock feed. A smaller percentage of soybeans are used directly for human consumption.

Immature soybeans may be boiled whole in their green pod and served with salt, under the Japanese name edamame (枝豆, edamame?). Soybeans prepared this way are a popular local snack in Hawaii, and are becoming increasingly popular in the continental United States. Because of the proclaimed health benefits of soy, edamame has been featured as an ideal snack alternative in fitness and healthy living magazines such as Real Simple. Edamame is sold in the frozen vegetable section at some larger grocery stores, and as ready-to-eat snackfood in many Asian delis.

In China, Japan, and Korea the bean and products made from the bean are a popular part of the diet. The Chinese invented tofu , and also made use of several varieties of soybean paste as seasonings. Japanese foods made from soya include: miso , natto , and edamame . In Korean cuisine, soybean sprouts, called kongnamul (hangul) are also used in a variety of dishes such as doenjang, cheonggukjang and ganjang.

The beans can be processed in a variety of ways. Common forms of soy (or soya) include soy meal, soy flour, soy milk, tofu, textured vegetable protein (TVP, which is made into a wide variety of vegetarian foods, some of them intended to imitate meat), tempeh, soy lecithin and soybean oil. Soybeans are also the primary ingredient involved in the production of soy sauce (or shoyu).
Archer Daniels Midland (ADM) is among the largest processors of soybeans and soy products. ADM along with Dow Chemical Company, DuPont and Monsanto support the industry trade associations United Soybean Board (USB) and Soyfoods Association of North America (SANA). These trade associations have increased the consumption of soy products dramatically in recent years.

Neutritional Value:
For human consumption, soybeans must be cooked with “wet” heat to destroy the trypsin inhibitors (serine protease inhibitors). Raw soybeans, including the immature green form, are toxic to all monogastric animals.

Soybeans are considered by many agencies to be a source of complete protein. A complete protein is one that contains significant amounts of all the essential amino acids that must be provided to the human body because of the body’s inability to synthesize them. For this reason, soy is a good source of protein, amongst many others, for vegetarians and vegans or for people who want to reduce the amount of meat they eat. According to the US Food and Drug Administration.

Protein, Vitamins, and Minerals:
Soybeans are generally considered to be a source of complete protein, without any need for Protein combining. although this is contested by some sources. A complete protein is one that contains significant amounts of all the essential amino acids that must be provided to the human body because of the body’s inability to synthesize them. For this reason, soy is a good source of protein, amongst many others, for many vegetarians and vegans or for people who cannot afford meat.

The gold standard for measuring protein quality, since 1990, is the Protein Digestibility Corrected Amino Acid Score (PDCAAS) and by this criterion soy protein is the nutritional equivalent of meat and eggs for human growth and health. Soybean protein isolate has a Biological Value of 74, whole soybeans 96, soybean milk 91, and eggs 97.

Soy protein is similar to that of other legume seeds, but has the highest yield per square meter of growing area, and is the least expensive source of dietary protein.

Soya Oil:
In processing soybeans for oil extraction and subsequent soy flour production, selection of high quality, sound, clean, dehulled yellow soybeans are very important. Soybeans having a dark colored seed coat, or even beans with a dark hilum will inadvertently leave dark specks in the flour, are undesirable for use in commercial food products. All commercial soybeans in the United States are yellow or yellow brown.

To produce soybean oil, the soybeans are cracked, adjusted for moisture content, rolled into flakes and solvent-extracted with commercial hexane. The oil is then refined, blended for different applications, and sometimes hydrogenated. Soybean oils, both liquid and partially hydrogenated, are exported abroad, sold as “vegetable oil,” or end up in a wide variety of processed foods. The remaining soybean husks are used mainly as animal feed.

The major unsaturated fatty acids in soybean oil triglycerides are 7% linolenic acid (C18:3); 51% linoleic acid (C-18:2); and 23% oleic acid(C-18:1). It also contains the saturated fatty acids 4%stearic acid and 10% palmitic acid.

Soybean oil has a relatively high proportion, 7–10%, of oxidation prone linolenic acid, which is an undesirable property for continuous service, such as in a restaurant. In the early nineties, Iowa State University developed soybean oil with 1% linolenic acid in the oil. Three companies, Monsanto, DuPont/Bunge, and Asoyia in 2004 introduced low linolenic, (C18:3; cis-9, cis-12, cis-15 octadecatrienoic acid) Roundup Ready soybeans. In the past hydrogenation was used to reduce the unsaturation in linolenic acid, but this produced the unnatural trans-fatty acid trans fat configuration, whereas in nature the configuration is cis. This external picture from North Dakota State University compares soybean oil fatty acid content with other oils.

Soybean oil has also been found effective as an insect repellent in some studies. The commercial product Bite Blocker contains soybean oil as one active ingredient

Soya Meal:
Soybean meal, the material remaining after solvent extraction of soybean flakes, with a 50% soy protein content, toasted (a misnomer because the heat treatment is with moist steam) and ground in a hammer mill, provided the energy for the American production method, beginning in the 1930s, of growing farm animals such as poultry and swine on an industrial scale; and more recently the aquaculture of catfish.
Soya Flour:
Soy flour refers to defatted soybeans where special care was taken during desolventizing (not toasted) in order to minimize denaturation of the protein to retain a high Nitrogen Solubility Index (NSI), for uses such as extruder texturizing (TVP). It is the starting material for production of soy concentrate and soy protein isolate.

*Defatted soy flour is obtained from solvent extracted flakes, and contains less than 1% oil.
*Full-fat soy flour is made from unextracted, dehulled beans, and contains about 18% to 20% oil. Due to its high oil content a specialized Alpine Fine Impact Mill must be used for grinding rather than the more common hammer mill.

*Low-fat soy flour is made by adding back some oil to defatted soy flour. The lipid content varies according to specifications, usually between 4.5% and 9%.

*High-fat soy flour can also be produced by adding back soybean oil to defatted flour at the level of 15%.

*Lecithinated soy flour is made by adding soybean lecithin to defatted, low-fat or high-fat soy flours to increase their dispersibility and impart emulsifying properties. The lecithin content varies up to 15%.

Soya Infant formula:
Infant formulas based on soy are used by lactose-intolerant babies and for babies that are allergic to cow milk proteins. The formulas are sold in powdered, ready-to-feed, or concentrated liquid forms.

Some reviews express the opinion that more research is needed to answer the question of what effect the phytoestrogens contained in soy formula may have on infants , but did not find any adverse effects. Diverse studies conclude there are no adverse effects in human growth, development, or reproduction as a result of the consumption of soy-based infant formula. One of these studies, published at the Journal of Nutrition, concludes that:

“…there is no clinical concerns with respect to nutritional adequacy, sexual development, neurobehavioral development, immune development, or thyroid disease. SBIFs provide complete nutrition that adequately supports normal infant growth and development. FDA has accepted SBIFs as safe for use as the sole source of nutrition”

Soya Nut butter:
Soybeans have been made into a spread called soynut butter, similar to peanut butter but with soybeans instead. It is less fattening than peanut butter.

Substitute for existing products:
Soybeans are the primary ingredient in many processed foods, including dairy product substitutes (e.g., margarine, soy ice cream, soy milk, soy yogurt, soy cheese and soy cream cheese), as well as Crisco, soybean oil, tofu, veggie burgers, soy crisps, among others. Soybeans are processed to produce a texture and appearance similar to other foods (e.g., butter, ice cream, milk, yogurt, cheese, lard, olive oil, ground beef, potato chips, etc.) and are readily available in most supermarkets. Soy milk does not contain significant amounts of calcium, since the high calcium content of soybeans is bound to the insoluble constituents and remains in the pulp. Many manufacturers of soy milk now sell calcium-enriched products as well.
Other products:
Soybeans are the bean used in Chinese fermented black beans, douchi, not the sometimes confused black turtle beans.

Soybeans are also used in industrial products including oils, soap, cosmetics, resins, plastics, inks, crayons, solvents, clothing, and biodiesel. Soybeans are also used as fermenting stock to make a brand of vodka.[citation needed]

Henry Ford promoted the soybean, helping to develop uses for it both in food and in industrial products, even demonstrating auto body panels made of soy-based plastics. Ford’s interest led to two bushels of soybeans being used in each Ford car as well as products like the first commercial soy milk, ice cream and all-vegetable non-dairy whipped topping. The Ford development of so-called soy-based plastics was based on the addition of soybean flour and wood flour to phenolformaldehyde plastics.

In 1931, Ford hired chemists Robert Boyer and Frank Calvert to produce artificial silk. They succeeded in making a textile fiber of spun soy protein fibers, hardened or tanned in a formaldehyde bath which was given the name Azlon by the Federal Trade Commission. Pilot production of Azlon reached 5000 pounds per day in 1940, but never reached the commercial market.

Today, very high quality textile fibers are made commercially from “okara” (soy pulp), a by-product of tofu production.

Consumption of soy may also reduce the risk of colon cancer, possibly due to the presence of sphingolipids.
THE ROLE OF SOYA FOODS IN DISEASE PREVENTION:
Omega-3 fatty acids
Omega-3 fatty acids, for example, alpha-linolenic acid C18-3, all cis, 9,12,15 octadecatrienoic acid (where the omega-3 refers to carbon number 3 counting from the hydrocarbon tail whereas C-15 refers to carbon number 15 counting from the carboxyl acid head) are special fat components that benefit many body functions. However, the effects which are beneficial to health are associated mainly with the longer-chain, more unsaturated fatty acids eicosapentaenoic (20:5n-3, EPA) and docosahexaenoic acid (22:6n-3, DHA) found in fish oil and oily fish. For instance, EPA and DHA, inhibit blood clotting, while there is no evidence that alpha-linolenic acid (aLNA) can do this. Soybean oil is one of the few common vegetable oils that contains a significant amount of aLNA; others include canola, walnut, and flax. However, soybean oil does not contain EPA or DHA. Soybean oil does contain significantly greater amount of omega-6 fatty acids in the oil: 100g of soybean oil contains 7g of omega-3 fatty acids to 51g of omega-6: a ratio of 1:7. Flaxseed, in comparison, has an omega-3:omega-6 ratio of 3:1.
Isoflavones:
Soybeans also contain the isoflavones genistein and daidzein, types of phytoestrogen, that are considered by some nutritionists and physicians to be useful in the prevention of cancer and by others to be carcinogenic[citation needed] and endocrine disruptive[citation needed]. Soy’s content of isoflavones are as much as 3mg/g dry weight.[citation needed] Isoflavones are polyphenol compounds, produced primarily by beans and other legumes, including peanuts and chickpeas. Isoflavones are closely related to the antioxidant flavonoids found in other plants, vegetables and flowers. Isoflavones such as genistein and daidzein are found in only some plant families, because most plants do not have an enzyme, chalcone isomerase which converts a flavone precursor into an isoflavone.

Claims of cholesterol reduction:
The dramatic increase in soyfood sales is largely credited to the Food and Drug Administration’s (FDA) approval of health claims for soy in which studies are conflicting as to their cholesterol lowering ability.

From 1992 to 2003, sales have experienced a 15% compound annual growth rate, increasing from $300 million to $3.9 billion over 11 years, as new soyfood categories have been introduced, soyfoods have been repositioned in the market place, thanks to a better emphasis on marketing nutrition

In 1995, the New England Journal of Medicine (Vol. 333, No. 5) published a report from the University of Kentucky entitled, “Meta-Analysis of the Effects of Soy Protein Intake on Serum Lipids.” It was financed by the PTI division of DuPont,”The Solae Co.”[34] St. Louis, Missouri, a soy producer and marketer. This meta-analysis concluded that soy protein is correlated with significant decreases in serum cholesterol, Low Density Lipoprotein LDL (bad cholesterol) and triglyceride concentrations. However, High Density Lipoprotein HDL(good cholesterol) did not increase by a significant amount. Soy phytoestrogens (isoflavones: genistein and daidzein) adsorbed onto the soy protein were suggested as the agent reducing serum cholesterol levels. On the basis of this research PTI, in 1998, filed a petition with FDA for a health claim that soy protein may reduce cholesterol and the risk of heart disease. It should be noted that only subjects with serum cholesterol of 250mg/dl and higher showed any improvement in the study.

The FDA granted this health claim for soy: “25 grams of soy protein a day, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease.” One serving, (1 cup or 240 mL) of soy milk, for instance, contains 6 or 7 grams of soy protein. Solae resubmitted their original petition, asking for a more vague health claim, after their original was challenged and highly criticized. Solae also submitted a petition for a health claim that soy can help prevent cancer. They quickly withdrew the petition for lack of evidence and after more than 1,000 letters of protest were received. In February 18, 2008 Weston A. Price Foundation submitted a petition for removal of this health claim.

In January, 2006 an American Heart Association review (in the journal Circulation) of a decade long study of soy protein benefits casts doubt on the FDA allowed “Heart Healthy” claim for soy protein. This review of the literature compared soy protein and its component isoflavones with casein (isolated milk protein), wheat protein, and mixed animal proteins. The review panel also found that soy isoflavones have not been shown to reduce post menopause “hot flashes” in women and the efficacy and safety of isoflavones to help prevent cancers of the breast, uterus or prostate is in question. Thus, soy isoflavone supplements in food or pills is not recommended. Among the conclusions the authors state, “In contrast, soy products such as tofu, soy butter, soy nuts, or some soy burgers should be beneficial to cardiovascular and overall health because of their high content of polyunsaturated fats, fiber, vitamins, and minerals and low content of saturated fat. Using these and other soy foods to replace foods high in animal protein that contain saturated fat and cholesterol may confer benefits to cardiovascular health.” The original paper is in the journal Circulation: January 17, 2006

SOY CONTROVERSY :

Phytoestrogen:
Soybeans contain isoflavones called genistein and daidzein, which are one source of phytoestrogens in the human diet. Since most naturally occurring estrogenic substances show only weak activity, it is doubtful that normal consumption of foods that contain these phytoestrogens would provide sufficient amounts to elicit a physiological response in humans.

Plant lignans associated with high fiber foods such as cereal brans and beans are the principal precursor to mammalian lignans which have an ability to bind to human estrogen sites. Soybeans are a significant source of mammalian lignan precursor secoisolariciresinol containing 13–273 µg/100 g dry weight. Another phytoestrogen in the human diet with estrogen activity is coumestans, which are found in beans, split-peas, with the best sources being alfalfa, clover, and soybean sprouts. Coumestrol, an isoflavone coumarin derivative is the only coumestan in foods.

Soybeans and processed soy foods do not contain the highest “total phytoestrogen” content of foods. A study in which data were presented on an as is (wet) basis per 100 g and per serving found that food groups with decreasing levels of total phytoestrogens per 100 g are nuts and oilseeds, soy products, cereals and breads, legumes, meat products, various processed foods that may contain soy, vegetables, and fruits.


In men:
Because of the phytoestrogen content, some studies indicate that there is an inverse correlation between soybean ingestion and testosterone in men.For this reason, they may be protected against the development of prostate cancer.

In women:
A 2001 lierature review suggested that women with current or past breast cancer should be aware of the risks of potential tumor growth when taking soy products, based on the effect of phytoestrogens on breast cancer cell growth in animals.

A 2006 commentary reviewed the relationship with soy and breast cancer. They stated that soy may prevent breast cancer, but cautioned that the impact of isoflavones on breast tissue needs to be evaluated at the cellular level in women at high risk for breast cancer.

In infant formula:
There are some studies that state that phytoestrogen in soy can lead to alterations in the proliferation and migration of intestinal cells. The effects of these alterations are unknown. However, some studies conclude there are no adverse effects in human growth, development, or reproduction as a result of the consumption of soy-based infant formula. Other reviews agree, but state that more research is needed to answer the question of what effect phytoestrogens have on infants. Soy formula has also been linked to autoimmune disorders of the thyroid gland.


Allergens:
About 8% of children in the USA are allergic to soybean proteins. The major soy allergen has been identified by scientists at USDA. Both transgenic and conventional soybean varieties without the allergenic protein have been prepared.Soy allergy, typically, will manifest itself approximately a day after consumption of the beans. Common symptoms are urticaria, rash, itching, and redness of the skin

Promotion as health food:
Soy consumption has been promoted by natural food companies and the soy industry’s aggressive marketing campaign in various magazines, television ads and in health food markets. Research has been conducted examining the validity of the beneficial health claims with regard to the increase in consumption of soybeans which mimic hormonal activity. A practice guideline published in the journal Circulation questions the efficacy and safety of soy isoflavones for preventing or treating cancer of the breast, endometrium, and prostate (although the same study also concludes that soy in some foods should be beneficial to cardiovascular and overall health) and does not recommend usage of isoflavone supplements in food or pills. A review of the available studies by the United States’ Health and Human Services’ Agency for Healthcare Research and Quality (AHRQ) found little evidence of substantial health improvements and no adverse effects, but also noted that there was no long-term safety data on soy consumption

In the brain:
Estrogen helps protect and repair the brain during and after injury. The mimicry of estrogen by the phytoestrogens in soy has introduced a controversy over whether such a replacement is harmful or helpful to the brain. Several studies have found soy to be harmful for rats. One study followed over 3000 Japanese men between 1965 and 1999, and that showed a positive correlation between brain atrophy and consumption of tofu. The study was rejected as not credible by the Food and Drug Administration when it issued its health claim for soy: “25 grams of soy protein a day, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease.”

As a carcinogen:
Raw soy flour is known to cause pancreatic cancer in rats. Whether this is also true in humans is unknown because no studies comparing cases of pancreatic cancer and soy intake in humans have yet been conducted, and the doses used to induce pancreatic cancer in rats are said to be larger than humans would normally consume. Heated soy flour may not be carcinogenic in rats.
