Health notes

Aluminium is not currently listed as an authorised food additive in the UK Register of Food Additive Authorisations. Therefore, it is not intentionally added to foods as a permitted additive. Concerns have been raised about aluminium accumulation in the body, but regulatory bodies like EFSA have evaluated aluminium compounds used in food. JECFA has also evaluated certain aluminium-containing substances, setting acceptable daily intakes for some.
