Reminds me of how Tic Tacs have "0g sugar" on the label.
You'd expect the average person to see this information and extrapolate that they are ingesting 0g of sugar whether they eat 1 or 100 Tic Tacs.
> Tic Tac® mints do contain sugar as listed in the ingredient statement. However, since the amount of sugar per serving (1 mint) is less than 0.5 grams, FDA labeling requirements permit the Nutrition Facts to state that there are 0 grams of sugar per serving.
Bizarre.
