Estimates. Portion weights are the published averages for this food. A cup of chopped carrot and a cup of sliced carrot do not weigh the same, so treat the result as approximate.
About zeros. A value of 0 may mean the nutrient is genuinely absent, or that it was not measured / was below the limit of detection. USDA does not distinguish between the two, so this site does not use 0 values for filtering or for "free from" claims.
This converter does not use zero values to claim a food is free of anything, and it is not dietary or medical advice.
