E-Numbers


  • E-numbers are food additives regulated and approved for use within the European Union. They’re added to alter the flavor, texture, shelf life, or appearance of food products. While these additives meet official safety standards, that doesn’t mean they support your health.

    Some can trigger adverse effects, especially when consumed frequently, in large quantities, or in combination with others. Certain E-numbers have been associated with inflammation, digestive disturbances, and hormonal imbalances. Individual responses vary, and for some people even approved additives may lead to serious issues. Opting for foods with no synthetic additives is a simple, impactful step toward protecting your long-term health.

  • Not all E-numbers are problematic. Some come from natural sources and may even offer health benefits. To help identify which additives raise concerns, the overview below classifies E-numbers into three categories:

    • Green signals substances that are generally harmless to the human body.

    • Orange points to additives that should be consumed only in limited amounts.

    • Red marks those best avoided due to potential health risks.

    The classification reflects a careful and critical approach. When safety data is incomplete or uncertain, the additive is placed in a more restrictive category to minimise potential risk.

  • E numbers are divided into the following groups:

    • E100-199: Colorants

    • E200-299: Preservatives/Food acids

    • E300-399: Antioxidants

    • E400-499: Emulsifiers

    • E500-599: Miscellaneous additives

    • E600-699: Flavour enhancers

    • E700-799: Preservatives

    • E900-999: Anti-foaming agents, glazing agents, dough improvers, sweeteners

    • E1400-1499: Modified starches
