Baker's yeast, known as Saccharomyces cerevisiae, is commonly used in baking and can also be found in some dietary supplements. When consumed, baker's yeast is typically deactivated by the acidic environment in the stomach and broken down by digestive enzymes. Therefore, it doesn't typically survive in the gut for an extended period.
While there isn't an exact timeframe for how long baker's yeast can survive in the gut, studies suggest that its survival is limited. The conditions in the gut, such as low pH and the presence of digestive enzymes, are not favorable for its survival. The yeast cells are likely to be broken down and digested before they have a chance to colonize or cause any significant effects.
It's important to note that the human body already harbors a variety of microorganisms in the gut, including natural yeast and bacteria. These microorganisms play a role in digestion and maintaining gut health. The consumption of baker's yeast in moderate amounts is generally considered safe for most individuals.
If you have any specific concerns about consuming baker's yeast or its effects on your health, it's always best to consult a healthcare professional who can provide personalized advice based on your situation.
