Ingredients are counted from the ingredients lists on Ocado's M&S listings. Each named ingredient counts once, including the parts of compound ingredients such as chocolate or crisped rice, and the vitamins and minerals added as fortification count as one.
Manufactured ingredients are those made by industrial processing rather than found in a kitchen, such as glucose syrup, protein isolates, added fibres, emulsifiers and flavourings. The share of manufactured ingredients is one of the signs Boone uses to judge whether a food is ultra-processed.
