Yeast in Yeast Infection vs Yeast in Bread: Understanding the Differences
Understanding the distinctions between the yeast causing infections and the yeast used in baking can help clarify misconceptions and provide important insights. While both yeasts belong to the fungal kingdom, they have distinct characteristics and roles in the body.
Introduction
The confusion between yeast used in baking and the yeast causing fungal infections can stem from the fact that both are fungi. However, the specific types of yeast and their effects on the human body are quite different. This article aims to demystify these differences and provide clarity.
The Yeast in Yeast Infections
The yeast associated with yeast infections, particularly vaginal yeast infections, is typically Candida albicans. This organism is part of the normal microbiome and can overgrow in certain conditions, leading to infections. Candida albicans is known for its ability to adapt to different environments within the human body and can cause a variety of symptoms, such as itching, discomfort, and irritation.
The Yeast Used in Baking Bread
Bread yeast, on the other hand, is usually Saccharomyces cerevisiae. This type of yeast is widely used in baking and brewing because it has a different function. When Saccharomyces cerevisiae ferments sugars, it produces carbon dioxide and alcohol, which help dough rise and give bread its characteristic texture and flavor. Despite being a type of yeast, Saccharomyces cerevisiae does not cause infections and is generally safe for consumption.
Recent Research: Similarities and Differences
A recently published study by a team of researchers led by Concordia University professor Malcolm Whiteway in Current Biology has shed new light on the similarities and differences between these yeasts. The research suggests that the yeast used in bread is less similar to the yeast causing infections than previously thought. This finding can have implications for reducing the risk of infections from beneficial bacteria present in sourdough bread.
It is worth noting that sourdough bread is fermented in a way that fosters more beneficial bacteria, which can work to reduce yeast populations. This means that the likelihood of infection and/or overgrowth is substantially lower when consuming sourdough bread compared to other types of bread. This is because the beneficial bacteria in sourdough can help keep Candida populations in check.
Conclusion
While both the yeast in yeast infections and the yeast used in making bread are types of fungi, they belong to different genera and have different roles and effects. Understanding these differences can help individuals make informed decisions about their health. If you suspect you have a yeast infection, it is important to seek treatment early to prevent complications.
