Five Guys UK publishes total sugar for every item, but total sugar includes the lactose in milk and the sugars in potatoes and vegetables, which is not what health guidance limits. Boone separates free sugars, the added and syrup sugars SACN sets a daily cap on, and ranks all 41 items on that basis.
