Yeast
Yeast is a type of fungus that has been used for centuries in baking and fermentation. It is commonly used to make bread dough rise by converting the natural sugars in the dough into carbon dioxide gas. This gas gets trapped in the dough causing it to expand and rise. Yeast is also used to ferment beer, wine, and other alcoholic beverages.Yeast is a good source of protein, fiber, and several important nutrients such as B vitamins and minerals like potassium and magnesium. It also contains selenium, an important trace mineral that has been linked to a lower risk of certain diseases. However, yeast may not be suitable for people who have an allergy to it, as it can cause inflammation and other symptoms such as rashes, itching, and difficulty breathing.
