The Claim
In healthy overweight men, an isocaloric high-fructose diet (25% energy) increases serum uric acid by 22 ± 52 μmol/L, while an isocaloric high-glucose diet decreases serum uric acid by 23 ± 25 μmol/L, with a statistically significant difference (P < .01).
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In healthy overweight men, consuming a diet where 25% of calories come from fructose raises blood uric acid levels, while a diet with the same number of calories from glucose lowers blood uric acid levels, and the difference between the two diets is statistically significant.
See the scientific wording
In healthy overweight men, a high-fructose diet (25% energy) increased serum uric acid by 22 ± 52 μmol/L during the isocaloric period, while a high-glucose diet decreased it by 23 ± 25 μmol/L, with a statistically significant difference (P < .01), indicating a distinct metabolic effect of fructose on uric acid production.
When fructose is processed in the liver, it rapidly uses up a molecule called ATP, which forces the liver to break down other molecules to replace it. This breakdown releases purines, which are then turned into uric acid. Glucose does not do this the same way, so it does not raise uric acid levels.
What the research says
1 studyWhen overweight men ate lots of fructose (like in sugary drinks), their blood uric acid went up, but when they ate the same amount of glucose (like in table sugar), their uric acid went down — proving fructose affects uric acid differently than other sugars.
