How we ranked

Based on the per-100 g values in USDA FoodData Central branded-food data, which come from manufacturers' labels. The ranking includes products in the matching USDA food category whose name contains “protein bar” or “protein snack bar” or “nutrition bar” or “high protein bar”, excluding names that contain “powder”, “shake”, “drink”, ordered by protein, highest first. When two bars have the same protein, the one with less sugar ranks higher. Values above 60 g per 100 g are treated as data-entry errors and left out. Matching by name can include or miss products, and formulations change — check the label.
