Purine and sugar, by the numbers
| Serving | 180 g |
|---|---|
| Purine per serving | under 1 mg (0% of the 400 mg daily guide) |
| Purine per 100 g | under 1 mg |
| Purine before GoutSafe's weighting | under 1 mg per serving |
| Main purine source | bread flour |
| Fructose per serving | 0 g |
| Added sugar per serving | not on the label |
| Total sugar per serving | not on the label |
Where the purine comes from
| Ingredient | Matched GoutSafe food | Purine in that food, per 100 g | Share of the product | Purine at that share, per serving | Counted in the worst case |
|---|---|---|---|---|---|
| tapioca flour | bread flour (A) | 26 mg | up to 2% | under 1 mg | under 1 mg |
Purine values come from each matched food's page on GoutSafe. Shares come from label order: US labels list ingredients by weight, so the second ingredient is at most half the product, and anything after "2% or less" is at most 2%. The worst case fills the most purine-dense ingredients to their full share first, until the shares reach the whole product, then applies GoutSafe's weighting by source, which counts plant purines at 0.3, dairy at 0 and organ meat at 1.3 because they raise uric acid by different amounts. The grade uses that worst case. How we rate.
Why it's rated C
- Open Food Facts classes it as ultra-processed (NOVA 4), and GoutSafe's rule keeps ultra-processed foods at Moderate (C) or below. Source on GoutSafe.
- Under 1 mg of purine per serving, well under 1% of the 400 mg daily guide. Source on GoutSafe.
Estimated from the ingredient label. Labels list ingredients by weight but rarely give amounts, so we grade on the most purine the label allows, which can read stricter than the real recipe and never safer. The label we read has no sugar line, so sugar is not part of this grade. How we rate.
