Benzoic acid (E210) is used as food preservative and is most suitable for foods, fruit juices, and soft drinks that are naturally in an acidic pH range.
Its use as preservative in food, beverages, toothpastes, mouthwashes, dentifrices, cos- metics, and pharmaceuticals is regulated.
Studies suggest that sodium benzoate may increase your risk of inflammation, oxidative stress, obesity, ADHD, and allergies. It may also convert to benzene, a potential carcinogen, but the low levels found in beverages are deemed safe.
It’s always wise to minimize your intake of processed foods and select personal care products with fewer man-made additives and more natural ingredients.
