Ketchup
Ketchup is low in purines and generally safe for people with gout in normal portions. A typical 16 g serving has about 2 mg of purines, under 1% of a ~400 mg working daily target. It also carries about 1.4 g of fructose per serving, which raises uric acid on its own.

How much can I eat?
A typical serving is about 16 g, which delivers 2 mg of purines, or under 1% of a ~400 mg working daily target.
Added fructose raises uric acid on its own, so keep sugary foods and drinks small. This is the fructose, not the total sugar: a sucrose-sweetened product carries roughly twice this much sugar overall.
Evidence: Ayoub-Charette et al., J Nutr 2021 (fructose by food source) · White et al., Am J Clin Nutr 2018 (whole apple vs. a fructose drink, matched dose)
Purines are not the limit here: even a large serving stays well within a ~400 mg working daily purine target. The sugar is what climbs with the portion.
Only part of these purines counts toward gout: the 2 mg here counts as roughly 1 mg toward your gout risk.
Ketchup is an easy choice to keep on hand.

Why grade B
Safe for most people in normal portions.
Added fructose raises uric acid as your body breaks it down, even when the purine number looks low.
Per 100 g (for comparison)
Low for gout (< 50 mg/100g).
High for gout (8–15 g/100g).
Processing: NOVA 3 of 4 (processed food). How processing affects the grade.
