What the function of baking powder in the body?

Baking powder is primarily a leavening agent used in cooking and baking, and it is not a nutrient that the body requires. When mixed with moisture and heat, it produces carbon dioxide gas, which helps doughs and batters rise, creating a light and fluffy texture. Ingesting baking powder in large amounts can lead to digestive issues and an imbalance in the body's acid-base levels, but it does not serve a specific physiological function in the body.
