Oranges
Fruit — purine content 19mg per 100g
Yes — can be eaten freely.
Diet Advice
Oranges are low in purine at about 19mg per 100g and high in vitamin C. Vitamin C from food is associated with modestly lower serum uric acid — a meta-analysis of 13 randomised trials found roughly a 0.35mg/dL fall with supplements — but the ACR does not recommend supplementing. The whole fruit beats orange juice, which is a concentrated fructose source.
Recommended Preparation
Eat the whole fruit rather than drinking the juice. If you do have juice, keep it to a small glass and make sure no sugar is added.
