摘要
Many additives, some of which have no nutritional value, can be legally used in processed foods. They intensify colour, thicken, increase shelf life and enhance flavour. Regulatory authorities issue approvals as safe within acceptable quantitative limits. Ultra-processed foods (UPFs) contain combinations of all these additives and are particularly attractive to children.Many publications suggest that artificial colourants, benzoate preservatives, non-caloric sweeteners, emulsifiers and their degradation derivatives have adverse effects by increasing risks of mental health disorders, attention deficit hyperactivity disorder, cardiovascular disease, metabolic syndrome and potential carcinogenic effects.A systematic review has established that artificial azo dye food colourants (AFCs) and sodium benzoate preservative cause disturbed behaviour in children. AFCs and benzoates in animal models have neurotoxic properties through gut microbial generation of toxic metabolites. Observational studies show associations between high emulsifier intake and cardiovascular disease. Animal models and in vitro studies have highlighted neurotoxic, cytotoxic, genotoxic and carcinogenic effects. High intake of non-caloric sweeteners has been linked to cardiovascular disease and depression in adults and is linked to childhood obesity.Little research has focused on children who are the largest consumers of UPFs. Potentially, they are a ticking time bomb for adult obesity, metabolic syndrome, cardiovascular diseases, mental health disorders and cancers. Based on risk/benefit analysis, azo dye AFCs should be banned. Benzoates, emulsifiers and sweeteners require assessment of quantitative limits and cumulative effects of combinations. Consumers purchasing UPFs require information through ingredient health warnings and recommendations to use natural unprocessed foods which have well-described health-promoting properties.
