Is Aerated silica a safe food additive?

Aerated silica, also known as silica gel or silicon dioxide, is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use as a food additive. It is commonly used as an anti-caking agent in powdered foods to prevent clumping. However, while it is considered safe in small amounts, excessive consumption may lead to health issues, so it should be used within recommended limits. As with any additive, it's essential to follow regulatory guidelines and monitor individual sensitivities.
