The Claim

The purine-to-protein ratio in low-carbohydrate diets (6.1 mg/g) is significantly higher than in standard hospital diets (5.0 mg/g), and this difference indicates that protein sources in low-carbohydrate diets are more purine-dense per gram of protein, which may amplify the risk of hyperuricemia even when protein intake is controlled.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

How it works
1 study reviewed
In plain English

Low-carbohydrate diets contain more purine per gram of protein than standard hospital diets, resulting in higher purine exposure from protein sources even when total protein intake is the same.

See the scientific wording

The purine-to-protein ratio in low-carbohydrate diets (6.1 mg/g) is significantly higher than in standard hospital diets (5.0 mg/g), indicating that the protein sources in low-carbohydrate diets are more purine-dense per gram of protein, which may amplify the risk of hyperuricemia even when protein intake is controlled.

Why this might work

When people eat protein sources with more purines per gram, their bodies break down more purines into uric acid, which builds up in the blood and raises its concentration.

    Even when eating the same amount of protein, low-carb diets have more purine than hospital diets — like getting more of the stuff that raises uric acid in every bite. This could make gout or high uric acid worse.
