Which ultra-processed foods are linked to cancer?

Consuming ultra-processed foods like mass-produced bread and chicken nuggets may increase the risk of cancer, according to a new study in the British Medical Journal.

Ultra-processed foods are, according to The Guardian, food items made in “factories with ingredients unknown to the domestic kitchen”. Such foods include Pot Noodle, ready meals, cakes and confectionery containing high levels of additives, preservatives, flavourings and colourings – and often high levels of sugar, fat and salt.
