Table Sugar (white)
Table Sugar (white) is fine in moderation. Watch your portion size, especially during a flare. A typical 8 g serving is essentially purine-free. It also carries about 4 g of fructose per serving, which raises uric acid on its own.
General information, not a substitute for advice from your doctor or dietitian.
This is a concentrated source of sugar: high in fructose, which raises uric acid on its own. A small amount is fine, but it is easy to overdo, so we do not rate it as safe to eat freely. The fructose figure counts both free fructose and the fructose released from sucrose.
How much can I eat?
A typical serving is about 8 g, which delivers 0 mg of purines, or about 0% 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.

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.
Table Sugar (white) fits in moderation, so portion is the thing to get right.

Why grade C
Fine in moderation. Mind your portion size, especially during a flare.
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).
Very high for gout (> 15 g/100g).
