Purine and sugar, by the numbers
| Serving | 8 fl oz (240 ml) |
|---|---|
| Purine per serving | 10 mg (3% of the 400 mg daily guide) |
| Purine per 100 g | at most 4 mg |
| Purine before GoutSafe's weighting | at most 34 mg per serving |
| Main purine source | grapefruit |
| Fructose per serving | 8.5 g |
| Added sugar per serving | not on the label |
| Total sugar per serving | 17 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 |
|---|---|---|---|---|---|
| grapefruit juice | grapefruit (A) | 14 mg | up to 100% | 34 mg | 10 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 A
- The label lists one food, so the grade is GoutSafe's own grade for grapefruit: A. Source on GoutSafe.
- About 10 mg of purine per serving, and at most 10 mg (3% of the 400 mg daily guide), mostly from grapefruit. Source on GoutSafe.
- The panel lists 17 g of total sugars per serving and no added-sugar line.
The label lists one food, so this product takes GoutSafe's own grade for it.
