Source and how to read this
Data: USDA FoodData Central, Foundation Foods, release 2025-12-18, FDC ID 1999629 — laboratory-analysed sample. Described in USDA as Mushrooms, white button; we shorten these names for readability and keep the original here. Values are per 100 g of edible portion as USDA reports them; a serving may be more or less.
Portion: "100 g" = 100 g is the primary household measure USDA records for this food. Per-100 g values let you compare foods; per-portion values are closer to what you actually eat.
% Daily Value: FDA Daily Values for adults and children 4+ (FDA, page updated 2024-03-05). "High" means ≥20% DV and "good source" 10–19% DV — FDA's labelling cut-offs (21 CFR 101.54), which apply per serving; we apply the same cut-offs to 100 g so foods can be compared. No DV exists for energy or total sugars, so those show no percentage.
