Yeast produces alcohol as a byproduct of fermentation. It also competes with bacteria over nutrients, so doesn’t that mean that yeast should actually help keep the bacteria population lower in the colon, and help reduce more harmful germs?
Also yeast doesn’t produce the strong sour, methane and sulferous odors that bacteria produce, it’s simply making small amounts of alcohol.
Who considers yeast bad for the colon? It’d have a hard time getting there anyway, through the stomach acids.
That said, though, reducing the bacteria population in the colon is a bad thing. We need those bacteria, and suffer from severe gastric distress without them. Colon bacteria are only a problem if they manage to get somewhere other than the colon.
I did a search and it turns out that Dr. Oz considers yeast bad.
Dr. Oz is a quack. Do not believe anything he writes. Ever.
Other quacks also believe this. Dr. Lawrence Wilson attributes yeast growth to “An extremely yin condition of the body.” and “Electromagnetic fields (EMFs) and EMF stress.” The amount of woo on the subject is depressing.
It’s not that big a deal. You can wipe out your colonic flora just by taking antibiotics, and everybody winds up taking antibiotics every once in a while. That’s why eating yogurt is suggested as a means of repopulating the colon with “good” bacteria. Even if you don’t, the flora will soon repopulate in any case. It’s impossible for it not to.
But “bad” bacteria come in a huge variety of forms and many are bad only for some individuals. Some bacteria ferment undigested lactose and those contribute the gas and bloating that are major uncomfortable symptoms of lactose intolerance. Those come in through the mouth and cause gastric distress, contrary to what you said.
The OP should stick to major trustworthy names to get medical information from. I’d suggest WebMD, the Mayo Clinic, and Harvard Health. Avoid sites with only one doctor’s name. They may not be all bad but beginners aren’t going to be able to tell the difference.
Yup, that’s always the right response to an opening question like this one.
“Why are green hats considered dangerous to owls?”
Impossible to say unless we have the source claim to examine, and for that, we usually need to be introduced to the claimant.
I once made a batch of beer that was apparently still pretty “active” with yeast and I can tell you that the group of friends that drank it enjoyed some spectacular gaseous side-effects.
Oh, yeah. Drink enough home brew and you’ll see (or smell/hear) the effects of live yeast in the colon very clearly. One friend managed to clear a windy intersection in downtown Las Vegas with a particularly…intense emission.
It’s mainly due to the yeast fermenting sugars that the intestine can’t, or hasn’t gotten to yet.
The linked site (which urges a “yeast colon cleanse”) includes lots of classic woo nonsense - the idea that yeast overgrowth is commonplace and causes a litany of ills, the claim that undigested food causes a horrible sludge in our colons necessitating a “cleanse”, germ theory denial, the myth that Pasteur “recanted” on his deathbed, and on and on.
Yeast i.e. Candida is part of our normal intestinal flora and typically causes no problems (though alterations in that flora/immune status can potentially cause/exacerbate disease in a relatively small minority of people). Candida is much more likely to cause fake diseases than real ones.
I find the parallels with early-20th colectomies intriguing - since people with a whole long list of issues obviously had fecal matter rotting in their colon and causing the problems, removal of the colon was the solution! (30,-50,000 are thought to have been performed through the 1940s.)
Yes. The breakfast taco I had Friday morning. I suspect the bacon was out too long at an improper temperature. I assure you that my internal was cleansed clear down to my toenails for about four days.
One thing I was trying to get across is that when it comes to microbes yeast is probably the lesser of many other evils, so to speak. ** If you somehow had zero yeast in your colon, then some other organism (something that is more harmful and produces more potent toxins) will take the yeast’s place.** Most yeast that live in humans aren’t very toxic. This is my understanding of the issue, but I probably over-simplified it.
