Is the food additive sodium benzoate harmful to humans?

Generally, whether sodium benzoate additives are harmful to the human body depends on specific circumstances. Moderate intake is usually safe, while excessive intake may be harmful. The detailed analysis is as follows:

Sodium benzoate is a food additive commonly used to inhibit microbial growth and extend the shelf life of food. It is an additive approved by food and drug regulatory authorities. When consumed in reasonable amounts, it is relatively safe and does not adversely affect health.

However, sodium benzoate is a salt compound that breaks down into benzoic acid and sodium ions after ingestion. Excessive intake of sodium benzoate increases sodium consumption, which may disrupt the body's acid-base balance and thus cause potential harm.

Therefore, to avoid adverse effects on health, it is recommended to choose fresh, unprocessed foods and reduce intake of sodium benzoate additives, which contributes to better overall health.
