What portion is the score based on?

Nutrition figures are given per 100 g, and the scoring applies a serving-size adjustment based on this food's typical portion: 1 cup (45 g). Eating substantially more or less than that shifts the real-world effect accordingly.

How confident is this score?

Based on the measured median for this food category. Because the purine figure is estimated rather than directly measured, read this score as approximate.
