Purines by serving size
Purines arrive by the gram, not by the label. This is the measured value above, scaled to portions you would actually eat.
| Portion | Total purines |
|---|---|
| Garnish or side (30 g) | 17 mg |
| Standard 100 g | 56 mg |
| Typical serving (150 g) | 84 mg |
| Large main course (250 g) | 140 mg |
Why the numbers vary
The soy foods and legumes measured here run from 45.9 mg to 192.4 mg per 100 g, so the category is a poor guide on its own — which specific food, and prepared how, decides almost everything.
