- Abstract
<bold>Background and Objectives: </bold>Overconsumption of drinks containing fructose increases the risk for hyperuricemia and gout. Comparative analysis evaluating the indicators of serum uric acid (SUA) load caused by natural food-derived fructose and pure fructose in sweeteners is lacking. We aimed to uncover the effect of fructose from apple and honey and pure fructose powder on the SUA concentration of healthy young Chinese individuals.<bold>Methods and Study Design: </bold>Two randomized crossover trials were performed. The participants were randomly assigned to consume apple or honey (test food) or pure fructose powder (reference food); one week later, the groups' dietary intervention was switched. Blood samples were collected at 0, 30, 60, and 120 min after meal to measure the SUA and blood glucose concentrations.<bold>Results: </bold>At 30 and 60 min, the SUA concentration in participants consuming apple or honey was lower than in those consuming fructose powder. At 120 min, the SUA concentration of participants consuming apple returned to baseline. The areas under the curve (AUC) within 2 h (2h- AUCs) of SUA exhibited the trend of fructose >honey >apple. The 2h-AUC ratio between test food and reference food was determined using the uric acid index to assess the efficiency of food-derived fructose in increasing the SUA concentration. The uric acid index of honey was higher than that of apple. Men had higher postprandial SUA concentration than women.<bold>Conclusions: </bold>Food-derived fructose caused a lighter load on uric acid metabolism than pure fructose. Uric acid index can be useful for distinguishing fructose-containing foods.
