* KaloCam calculated these percentages from the amounts above using FDA Daily Values; the brand did not publish these percentages.
Unmarked percentages are published by the brand, per stated serving. A dash means no percentage is shown. FDA Daily Values are for adults and children age 4 and older; the Daily Value for added sugars is 50 g.
“Not published” means a numeric amount is not given in the official information used here; it does not mean zero. Less-than amounts stay as printed. No serving weight is inferred from calories or per 100 g values.
