What is Yeast?

Yeast is a type of fungus that is essential in various food processes, particularly in baking and fermentation. It facilitates the conversion of sugars into alcohol and carbon dioxide, which is crucial for leavening bread and producing alcoholic beverages. Yeast is typically grown on carbohydrate-rich substrates such as glucose, molasses, or other sugars.

Why People Avoid Yeast

People on a corn-free diet may avoid yeast because it is often cultivated on corn-derived sugar sources. The growth medium for yeast can include glucose or dextrose, which might be sourced from corn. Since the specific origin of these sugars is not always labeled on products, individuals with strict corn-free dietary restrictions should contact manufacturers to verify the source of the yeast's growth medium.
