Test your knowledge in eight questions to prove you know your onions from your emulsifiers

A major global report released this week linked ultra-processed foods to harm in every major human organ. For people in the US, the UK and Australia, these foods make up more than half the calories they consume each day.

But it’s not always easy to tell which foods are ultra-processed.

Group one: unprocessed or minimally processed foods including whole fruits and vegetables, milk, oats and rice.

Group two: processed basic ingredients used in cooking including salt, sugar and vegetable oils.

Group three: processed foods made by adding items from groups one and two. Includes canned legumes, bread and cheese.

Group four: ultra-processed foods which are commercial products made from extracts of foods, often with added chemicals, flavours and other ingredients you wouldn’t find in a home kitchen.
