Agave Nectar (syrup)

How much can I eat?
A typical serving is about 21 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.
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.
Agave Nectar (syrup) fits in moderation, so portion is the thing to get right.
