What Are Food Additives and E-Numbers?

Food additives are substances added to food to preserve flavour, enhance taste, or improve appearance. In the UK and EU, these additives are assigned E-numbers — standardised codes that identify specific additives like preservatives, colourings, sweeteners, and emulsifiers.

Whilst many additives are safe, some have been linked to health concerns including allergic reactions, hyperactivity in children, and digestive issues. Understanding which E-numbers are in your food helps you make informed choices about what you eat.
