Purine and sugar, by the numbers
| Serving | 12 fl oz (355 ml) |
|---|---|
| Purine per serving | about 57 mg, at most 106 mg (27% of the 400 mg daily guide) |
| Purine per 100 g | at most 30 mg |
| Purine before GoutSafe's weighting | at most 214 mg per serving |
| Main purine source | dried yeast |
| Fructose per serving | 0 g |
| Added sugar per serving | not on the label |
| Total sugar per serving | 0 g |
The weighted figure is lower than the one before weighting because GoutSafe counts purine from plants at a fraction of the same amount from meat or fish. The grade uses the weighted figure.
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 |
|---|---|---|---|---|---|
| yeast | dried yeast (D) | 847 mg | up to 2% | 60 mg | 60 mg |
| malt | barley (A) | 44 mg | up to 100% | 157 mg | 46 mg |
| hops | barley (A) | 44 mg | up to 2% | 3 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.
- About 57 mg of purine per serving, and at most 106 mg (27% of the 400 mg daily guide), mostly from yeast (dried). Source on GoutSafe.
- The panel lists 0 g of total sugars per serving and no added-sugar line.
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. Sugar comes from the Nutrition Facts panel. How we rate.
