Lettuce

This is lettuce's own sorbitol content, not a recipe amount. Sorbitol is a polyol — a type of sugar alcohol — calculated from two official food-composition databases, Germany's Bundeslebensmittelschlüssel (BLS 4.0) and the French Ciqual table. Recipes are evaluated separately against a 0.20 g threshold (a per-serving cutoff from Varney et al. 2017, Journal of Gastroenterology and Hepatology, applied to one reference serving of the recipe) — an ingredient's own figure isn't directly comparable to that number, since a recipe combines several ingredients in different amounts. This describes the food, not a guarantee about how your body will respond to it.

These are lettuce's own fructose figures, not a recipe amount. Total fructose is how much fructose the food contains. Excess fructose is fructose minus glucose, counted only when positive, since glucose helps the body absorb fructose — it is the figure behind the "Low fructose" filter and the recipe figures. When measured, both come from two official food-composition databases, Germany's Bundeslebensmittelschlüssel (BLS 4.0) and the French Ciqual table. Recipes are evaluated separately against a 0.40 g threshold of excess fructose (a per-serving cutoff from Varney et al. 2017, Journal of Gastroenterology and Hepatology, applied to one reference serving of the recipe) — an ingredient's own figure isn't directly comparable to that number, since a recipe combines several ingredients in different amounts. This describes the food, not a guarantee about how your body will respond to it.
