The Claim

A 42-day low-purine, energy-restricted, and balanced diet improves estimated glomerular filtration rate by 3.8 mL/min/1.73m² and reduces serum creatinine by 4.2 μmol/L in male gout patients, indicating enhanced renal function independent of changes in blood pressure or hydration.

Cause and effect
1 study reviewed
In plain English

In men with gout, following a low-purine, calorie-restricted, and balanced diet for 42 days increases kidney filtration rate by 3.8 mL/min/1.73m² and lowers blood creatinine by 4.2 μmol/L, showing improved kidney function without changes in blood pressure or hydration levels.

See the scientific wording

A 42-day low-purine, energy-restricted, and balanced diet improves estimated glomerular filtration rate by 3.8 mL/min/1.73m² and reduces serum creatinine by 4.2 μmol/L in male gout patients, suggesting enhanced renal function independent of changes in blood pressure or hydration.

Why this might work

Eating less purine-rich food lowers the amount of uric acid made in the liver, while eating more vegetables blocks kidney tubes from reabsorbing uric acid, allowing more of it to leave the body. This reduces the burden on the kidneys, lets them filter blood more efficiently, and lowers creatinine levels without changing blood pressure or fluid levels.

  1. Study: Efficacy of a Low-Purine, Energy-Restricted and Balanced Diet on Hyperuricemia and Metabolic Profiles in Gout Patients: A Randomized Controlled Trial

    This diet helped men with gout flush out more uric acid through their kidneys, which means their kidneys were working better — even though the study didn’t measure kidney filtration directly, this is a strong sign it improved.
