A number looks wrong
Values marked ~ estimated were taken from the nearest matching food in a public composition database, not from the label — the label did not declare them. The screen names the food it matched, and you can change it.
Values marked unknown mean nobody has measured that nutrient for that product. Vitals would rather say so than invent a figure.
