Consumption of ultra-processed foods and cancer risk : results from NutriNet-Santé prospective cohort


  • Consumption of ultra-processed foods and #cancer risk: results from NutriNet-Santé prospective cohort | The BMJ

    Firstly, ultra-processed foods often have a higher content of total fat, saturated fat, and added sugar and salt, along with a lower fibre and vitamin density.101112131415161719 Beyond nutritional composition, neoformed #contaminants, some of which have carcinogenic properties (such as #acrylamide, heterocyclic amines, and polycyclic aromatic hydrocarbons), are present in heat treated processed food products as a result of the Maillard reaction.20 Secondly, the packaging of ultra-processed foods may contain some materials in contact with food for which carcinogenic and endocrine disruptor properties have been postulated, such as #bisphenol A.21 Finally, ultra-processed foods contain authorised,22 but controversial, food additives such as sodium #nitrite in processed meat or #titanium_dioxide (#TiO2, white food pigment), for which carcinogenicity has been suggested in animal or cellular models.2324

    In this large prospective study, a 10% increase in the proportion of ultra-processed foods in the diet was associated with a significant increase of greater than 10% in risks of overall and breast cancer. Further studies are needed to better understand the relative effect of the various dimensions of processing (nutritional composition, food additives, contact materials, and neoformed contaminants) in these associations.
