Uric Acid

Uric acid above roughly 5.5 mg/dL in men or 5.0 mg/dL in women associates with higher prevalence of hypertension, type 2 diabetes, chronic kidney disease, and cardiovascular events across multiple large cohorts. Mendelian randomization studies suggest the relationship is at least partly causal for hypertension and may be causal for cardiovascular events, although the evidence is not unanimous. Gout itself, the most direct downstream consequence, becomes substantial above 7 mg/dL, but the metabolic signal kicks in well below that threshold. Fructose is a particularly potent driver of uric acid because its hepatic metabolism consumes ATP, generates AMP, and ultimately yields uric acid as a byproduct. This is one of the proposed mechanisms by which high-fructose intake contributes to non-alcoholic fatty liver disease and metabolic syndrome. Alcohol elevates uric acid through both increased production and impaired renal clearance, which is why alcohol-driven gout flares are so consistently reported. The marker responds quickly to reductions in alcohol, added sugar, and animal-organ intake, usually within four to six weeks of meaningful dietary change.
