Sugar sources named in the ingredient list: sugar.

NHS daily free sugar limits: 30g for adults and children 11+, 24g age 7 to 10, 19g age 4 to 6.

Processing and additives: Pret A Manger Tuna & Cucumber

Boone classifies Pret A Manger Tuna & Cucumber as NOVA group 4, ultra-processed, based on Pret’s published ingredient list. NOVA groups foods by how far they are from their whole-food form, not by how nutritious they are. A group 4 food is not automatically unhealthy, and a group 1 food is not automatically healthy.
