Why are raw soybeans toxic to humans?
Raw soybeans are toxic to humans and most animals because they have high levels of protease inhibitors. Soybeans, a species of legume, are a very important crop for protein and oil. To eat soybeans, they must first be boiled in water. The boiling process ensures all toxic tryspin inhibitors are destroyed.

What are the effects of soybeans on the body?
Soybeans contain lectins, glycoproteins that bind to carbohydrates in cells. This can damage the cells or lead to cell death in the gastrointestinal tract. Lectins may bind to the intestinal walls, damaging the cells and affecting nutrient absorption as well as causing short-term gastrointestinal side effects.
What is the purpose of boiling soybeans?
Since protease inhibitors are heat-sensitive, boiling soybeans at 212 degrees F for 15 to 30 minutes improves their nutritional value, according to the textbook "Food Safety and Toxicity ."
Can you eat raw soybeans?
Many plant foods are perfectly safe to eat raw, but soybeans aren't among them. Some of the components found in raw soybeans can cause short term digestive problems, as well as possible long-term health issues. Cooking or fermentation neutralizes some of the negative side effects raw soybeans could have on your health.
Can you break down saponins?
Enzymes used in fermentation, however, can break down saponins. Like lectin, saponins can damage the cells of the intestines if eaten in large amounts. Saponins also impart a bitter taste to raw soybeans. Cooking methods can leach some of the saponins out of the soybeans, removing the bitter taste.
Can raw soybeans cause nausea?
Lectins and saponins in raw soybeans can cause acute nausea, gas, abdominal pain, diarrhea or vomiting. In large amounts, ingestion could lead to weight loss, failure to thrive or death. Raw soybeans could cause long-term damage to organs and tissues if you ingest them in large amounts.
Why are soybeans bad for you?
If these enzymes are kept from working, the food -- in this case, soybeans -- cannot be digested. That is why raw soybeans cause such symptoms of gastric distress. Cooking destroys the protease inhibitors in soybeans so they can be digested.
Why is cooking so bad for soybeans?
Cooking destroys the protease inhibitors in soybeans so they can be digested. Soybeans naturally contain protease inhibitors that keep the digestive enzymes from working. If these enzymes are kept from working, the food -- in this case, soybeans -- cannot be digested.

Fat-free (defatted) soybean meal is a significant and cheap source of protein for animal feeds and many packaged meals.
What are the phytosterols in soybean oil?
Within soybean oil or the lipid portion of the seed is contained four phytosterols: stigmasterol, sitosterol, campesterol, and brassicasterol accounting for about 2.5% of the lipid fraction; and which can be converted into steroid hormones. Additionally soybeans are a rich source of sphingolipids.
How long does it take for soybeans to flower?
Flowering is triggered by day length, often beginning once days become shorter than 12.8 hours. This trait is highly variable however, with different varieties reacting differently to changing day length. Soybeans form inconspicuous, self-fertile flowers which are borne in the axil of the leaf and are white, pink or purple. Depending of the soybean variety, node growth may cease once flowering begins. Strains that continue nodal development after flowering are termed " indeterminates " and are best suited to climates with longer growing seasons. Often soybeans drop their leaves before the seeds are fully mature.
What are the soluble carbohydrates in soybeans?
The principal soluble carbohydrates of mature soybeans are the disaccharide sucrose (range 2.5–8.2%), the tri saccharide raffinose (0.1–1.0%) composed of one sucrose molecule connected to one molecule of galactose, and the tetrasaccharide stachyose (1.4 to 4.1%) composed of one sucrose 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, so contribute to flatulence and abdominal discomfort in humans and other monogastric animals, comparable to the disaccharide trehalose. Undigested oligosaccharides are broken down in the intestine by native microbes, producing gases such as carbon dioxide, hydrogen, and methane .
Is soy based food organic?
There is no such thing as an all-natural soy-based food, because soybeans are toxic in their natural state. Processing is essential for soy foods, because soy is poisonous in its natural organic state (containing natural insecticides), so there are never truly organic soy products for human consumption.

Etymology
The word "soy" originated as a corruption of the Cantonese or Japanese names for soy sauce (Chinese: 豉油; Jyutping: si6jau4; Cantonese Yale: sihyàuh) (Japanese: 醤油, shōyu).
The etymology of the genus, Glycine, comes from Linnaeus. When naming the genus, Linnaeus observed that one of the species within the genus had a sweet root. Based on the sweetness, the Greek word for sweet, glykós, was Latinized. The genus name is not related to the amino acid gly…
Classification
The genus Glycine Willd. is divided into two subgenera, Glycine and Soja. The subgenus Soja (Moench) F.J. Herm. includes the cultivated soybean, Glycine max (L.) Merr., and the wild soybean, Glycine soja Sieb. & Zucc. Both species are annuals. Glycine soja is the wild ancestor of Glycine max, and grows wild in China, Japan, Korea and Russia. The subgenus Glycine consists of at least 25 w…
Description
Like most plants, soybeans grow in distinct morphological stages as they develop from seeds into fully mature plant.
The first stage of growth is germination, a method which first becomes apparent as a seed's radicle emerges. This is the first stage of root growth and occurs within the first 48 hours under ideal growing conditions. The first photosynthetic structures, …
Cultivation
During World War II, soybeans became important in both North America and Europe chiefly as substitutes for other protein foods and as a source of edible oil. During the war, the soybean was discovered as fertilizer due to Nitrogen fixation by the United States Department of Agriculture.
Cultivation is successful in climates with hot summers, with optimum growin…
Production
In 2020, world production of soybeans was over 353 million tonnes, led by Brazil and the United States combined with 66% of the total (table). Production has dramatically increased across the globe since the 1960s, but particularly in South America after a cultivar that grew well in low latitudes was developed in the 1980s. The rapid growth of the industry has been primarily fueled by large i…
