Earlier quoted context omitted.
No one eats a single grain of rice or a single chip, or can count how many they do eat (certainly in the case of rice). It's a rather silly comparison. A single tic-tac is not that far-fetched, and perhaps more realistic than you might think. In the end, "serving size" is a rather personal thing. And it's misleading, yes, but only by rounding everything down to 0.
> No one eats a single grain of rice or a single chip... Nor a single TicTac, for the most part. I'm sure there's someone out there who does, but it's certainly not standard practice. A box that's full of a food item that's 95% sugar simply shouldn't be able to list itself as zero sugar.
Obviously; we already agreed on that from the start. All that remains is the (IMHO very minor) disagreement whether the information should be listed "per capsule", "per n capsules", or "per n weight unit(s)", or "per box". It seems to me that "per capsule" is by far the easiest for consumers as that's the easiest, but it's really a minor detail.
