Both sides start at 100 grams so the first result is a fair like-for-like comparison.
How comparison works
Same basis. Honest gaps.
Every comparison begins with locally stored per-100-gram values from USDA FoodData Central, then scales them to the amount you choose. A documented household serving is used only when the source supplies its gram weight.
Food composition varies by variety, brand, preparation, and laboratory method. “Not reported” is different from zero, and this tool keeps that distinction visible.
