The Claim

Low-carbohydrate diets in healthy Japanese adults provide an average daily purine intake of 697.6 mg, which is higher than the 400 mg daily limit recommended for individuals with hyperuricemia, while standard hospital diets provide 340–349 mg/day, indicating a greater purine burden from low-carbohydrate dietary patterns.

Description
1 study reviewed
In plain English

Healthy Japanese adults on low-carbohydrate diets consume about 698 mg of purine per day, which is above the 400 mg daily limit advised for people with hyperuricemia, while hospital diets provide 340–349 mg per day.

See the scientific wording

Low-carbohydrate diets in healthy Japanese adults contain an average of 697.6 mg of purine per day, significantly exceeding the recommended daily intake limit of 400 mg for individuals with hyperuricemia, while standard hospital diets average 340–349 mg/day, suggesting that low-carbohydrate dietary patterns may pose a higher purine burden that could exacerbate hyperuricemia.

Why this might work

Eating foods high in purine causes the liver to break them down into uric acid, which builds up in the blood because the kidneys cannot remove it fast enough.

What the research says

1 study
  1. Study: Purine Content and Renal Acid Load Evaluation in Healthy Japanese Diets.

    This study found that low-carb diets in Japan have almost twice as much purine as regular hospital meals — 700 mg vs. 340 mg — and since people with high uric acid should stay under 400 mg, this diet could make their condition worse.
