Purine and sugar, by the numbers

Serving1 bar (40 g)
Purine per servingabout 6 mg, at most 14 mg (4% of the 400 mg daily guide)
Purine per 100 gat most 36 mg
Purine before GoutSafe's weightingat most 48 mg per serving
Main purine sourcesoy protein concentrate
Fructose per serving3.8 g
Added sugar per serving5 g
Total sugar per serving7 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

IngredientMatched GoutSafe foodPurine in that food, per 100 gShare of the productPurine at that share, per servingCounted in the worst case
soy protein isolate soy protein concentrate (A) 192 mg up to 50% 38 mg 12 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 6 mg of purine per serving, and at most 14 mg (4% of the 400 mg daily guide), mostly from soy protein concentrate. Source on GoutSafe.
  • The Nutrition Facts panel lists 5 g of added sugar per serving, about half of it fructose. Source on GoutSafe.
  • High-fructose corn syrup is listed on the label. 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. Sugar comes from the Nutrition Facts panel. How we rate.
