E408, or benzoic acid, is a food additive widely used in the food industry as a preservative.
Benzoic acid has antimicrobial properties and helps extend the shelf life of products by preventing the growth of mold, yeast, and bacteria.
Benzoic acid is most commonly used in pickled cucumbers, juice, syrups, jellies, and as an antioxidant in fats and oils.
Although benzoic acid is considered relatively safe for health when consumed in moderation, many advocates of the keto diet recommend minimizing the intake of food additives in general and opting for fresh, natural products.
