, sugar molecules that the body can’t break down entirely. With nowhere to go, these oligosaccharides hang out in the digestive tract, where they ferment, causing gas and bloating.
Soy protein does cause gas. Like most other beans, peas and other legumes, soy contains compounds called oligosaccharides. These three which I’ll cover in more detail, verbascose, stachyose, and raffinose are the primary culprits in flatulence caused by soy.
Too much protein: Protein farts can happen no matter what the source of your protein is if you are consuming too much of the stuff. When soy protein is concentrated or isolated, most (if not all) of the fiber is removed from the soy. Ways to offset this are to increase your intake of fiber to make sure you are getting at least 25 – 38 grams a day.
Soy intolerance will cause stomach pain, cramping, bloating, gas, diarrhea and nausea because the undigested soy proteins cause inflammation in your digestive system. Is It an Allergy? A soy allergy is different from soy intolerance and may cause indigestion and bloating.
Soy Intolerance. Soy intolerance will cause stomach pain, cramping, bloating, gas, diarrhea and nausea because the undigested soy proteins cause inflammation in your digestive system.
How much soy flour causes less gas?
It also has to do with how much soy products you are consuming. 30g of soy flour will cause you less gas than 80g.
Nowadays, soy has been getting a bad rap, and not without its reasons. It’s blamed for a whole range of ills from upset stomach to hormone imbalances.
The most common soy protein product out there is soy protein isolate (SPI). This is a product that boasts 90% protein.
There are at least 16 different types of soy protein allergens identified. A lot of us think of food allergies as resulting in skin hives or respiratory troubles. But gastrointestinal upset is actually one of the main categories of allergic reactions that can happen if you are allergic to a certain food.
Like most other beans, peas and other legumes, soy contains compounds called oligosaccharides. These three which I’ll cover in more detail, verbascose, stachyose, and raffinose are the primary culprits in flatulence caused by soy.
It is estimated that less than one percent of the general population suffers from a genuine soy allergy. This number seems to be growing, however, as does the incidence of soy intolerance.
As I mentioned, soy protein is commercially available in three different forms.
How to reduce phytate content in soybeans?
Unfortunately, soybeans have been found to be highly resistant to traditional phytate-reducing techniques like cooking, soaking, and sprouting (which works for other legumes and whole grains that also have phytates), and the only way to significantly reduce the phytate content of soybeans is through fermentation. 5.
Soybeans are roughly 41% protein, and a half a cup of boiled soybeans provides nearly 15 g protein, which is about twice the amount found in other legumes. It not only has a high protein content, but this vegetarian protein is also of a quality similar to that of animal proteins.
That’s because soy is loaded with fiber and oligosaccharides, prebiotic compounds that help feed our healthy gut bacteria, but are also known to cause flatulence and bloating.
For a little bit of background, soybeans were initially used in the U.S. as a commercial crop during the early 1900s. It wasn’t until fat and oil imports were blocked during World War II that we actually started to eat the beans. And once the FDA approved a health claim in 1999 that consuming 25 grams of soy protein could reduce the risk of heart disease—along with the rise of many plant-based animal and dairy alternatives —soybean production and consumption has blossomed. Now, soy is the U.S.’s second largest crop in cash sales, making America the leading soybean producer and exporter in the world, according to the American Soybean Association.
Soy and its influence on breast cancer have long been a source of concern. Soy contains phytoestrogens, naturally occurring hormone-like compounds with weak estrogenic effects, which—in the lab—have shown to fuel many cancers.
So with all these negative health effects out of the way, what’s the bottom line here? Should you be eating soy? Smith reiterates that there isn’t really any hard evidence that soybeans are unhealthy, so the only reason she personally doesn’t recommend it is because many people are already eating it in excess (which is never a good thing) in processed foods and because the most common source of soy “is really processed and genetically modified”—that’s the whole problem.

What percentage of soy is soluble?
Carbohydrates in soy generally constitute 30 percent of the bean and break down into soluble sugars of sucrose (5 percent), stachyose (4 percent), raffinose (1 percent) and insoluble fiber (20 percent). The insoluble fiber consists of cellulose and pectins, which are not digested by the enzymes of the GI tract, …
One solution proposed by the soy industry is genetically modified strains of soybeans that are low in the two stooges Raf and Stach. Plant scientists have already developed a strain known as “High Sucrose Soybeans” that contains more sucrose and less indigestible carbohydrates than ordinary beans.
THE TWO STOOGES: RAF AND STACH. The chief culprit, as with all beans, is the oligosaccharides in the carbohydrate portion. The word oligosaccharides comes from oligo (few) and saccharides (sugars). The best known oligosaccharides in beans are raffinose and stachyose.
Qualified scientists have measured numbers of incidences per hour and day: the quantities of gas ejected per incident, the proportions of hydrogen, methane, carbon dioxide, hydrogen sulfide, methanethiol and other gases; and even propulsion force and noise levels.
Since the average American prefers to do just that, the soy industry has acknowledged that the “flatul ence factor” must be overcome if soyfoods are ever to become a major part of the American diet. 2,3 .
In theory, tofu should be a low gas producer because oligosaccharides concentrate in the whey (the soaking liquid) and not the curds (the part sold as tofu). 18 Some Raf and Stach remain, however, and tofu is a gas producer for many consumers.
Soy-food eaters who suffer from truly excessive amounts of gas may be victims of undiagnosed soy allergies or sensitivities, and/or celiac disease. Obvious allergic symptoms to soy include sneezing, runny nose, hives, diarrhea, facial swelling, swollen tongue, shortness of breath and anaphylactic shock.
