Food preservatives are substances added to food to prevent spoilage and extend shelf life. They can be natural or synthetic, and they work by inhibiting the growth of bacteria, mold, and other microorganisms. While some preservatives are essential for ensuring the safety of food, others are used simply to extend shelf life and improve appearance.
There are many reasons to avoid food preservatives. Some preservatives have been linked to health problems, such as cancer, reproductive problems, and developmental disorders. Others may simply be unnecessary, as there are many natural ways to preserve food without resorting to chemicals.
