In casual language in the UK and Ireland, "E number" is used as a pejorative term for artificial food additives, and products may promote themselves as "free of E numbers" even though most of the (natural) ingredients contain components that also have an E number[citation needed] (e.g. Vitamin C (E300) or lycopene (E160d), the colour in tomatoes). To have a diet without any components that have an E number is basically impossible. "Free of E numbers" thus refers mainly to the lack of additives, not to the absence of components with an E number.
NB: Not all examples of a class fall into the given numeric range. Moreover, many chemicals, particularly in the E400–499 range, have a variety of purposes.
