Methodology & limits
PUFA grams are estimates built from each chain's published nutrition data and its disclosed or industry-default cooking oil, averaged across the scored menu items. Values are rounded; minor last-digit differences are intentional. Grades: A under 4g, B 4-6g, C 6-8g, D 8-12g, F over 12g average per item. Preparation varies by location and oils change, so treat values as directional. Building an app, map layer, or study on top of this? Also see the live API.
