Every spud passes the government's nutrient profiling model, helped by the fibre in the potato, but most carry cheese, which is where the saturated fat sits: 10g to 17g a portion, at least half a woman's daily guideline.
The 22 items in this section range from 341 kcal for the Subway Jacket Potato and Baked Beans up to 738 kcal for the Subway Big Breakwich Spud. Boone separates free sugars from the sugars that occur naturally in vegetables and milk, which NHS daily limits do not count, and measures every figure against the guideline for a specific age and sex rather than an adult average.
