a satiety booster. Exceptional fullness per calorie — but at only 13 kcal per 100 g, it can't fill you up on its own. Its power is making a meal bigger and more filling at almost no calorie cost; pair it with protein.

Why this score
The first three bars are sub-scores (0–100 per lever) that build the score; the values under each label are the measured quantities that drive them. Hyper-palatability works the other way — it cuts the built score by the shown percentage (up to −80%). Full math here.

Per 100 g. Source: usda-sr-legacy #168429 — listed by USDA as “Lettuce, butterhead (includes boston and bibb types), raw”. Every number is traceable, every score recomputable. How the score works. This entry came from a bulk USDA import and hasn’t been hand-reviewed yet — the numbers are USDA’s, but the name and grouping haven’t had a second pair of eyes.
