Yeast, a type of fungi, holds significant importance in various industries, particularly in baking and fermentation processes. Its ability to convert sugars into carbon dioxide and alcohol makes it a key ingredient in bread, beer, and other food and beverage products. However, yeast overgrowth in certain contexts, such as infections, can lead to health issues, especially in individuals with weakened immune systems. Maintaining a balanced yeast environment in both industrial processes and health contexts is essential to harness its beneficial effects while avoiding potential complications.
