Subway Footlong Subs: calories, sugar and salt for every item

Subway's footlong figures are its 6 inch figures doubled, so the choice of filling matters twice over. A footlong Spicy Italian carries 6.4g of salt, more than an adult's entire daily maximum, before any cheese or sauce.

The 18 items in this section range from 454 kcal for the Subway Veggie Delite Footlong Sub up to 1078 kcal for the Subway Garlic Cheesesteak Footlong Sub. 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.
