This game compares per-100-gram nutrition values for fruits and vegetables, using USDA food-composition data where a clean raw-produce match exists.

• Each round compares one published raw produce value per 100 grams, so a berry is being measured against a beet on the same weight basis.
• USDA FoodData Central is the preferred source whenever the produce item lines up cleanly with a raw commodity entry, with Wikipedia produce nutrition pages used only as a fallback.
• Cultivar, ripeness, storage, and raw-versus-prepared conventions can all move the number around the edges, so treat the value as a comparative baseline.

Sugar here is concentration by weight, not sweetness as people actually experience it bite by bite.
