You don’t seem to be getting the point. The idea is so you can compare the nutritional value using a standard measurement size, no matter how big the bottle is.

You don’t seem to be getting the point. The idea is so you can compare the nutritional value using a standard measurement size, no matter how big the bottle is. Knowing how much sodium is in something is not very useful when shopping if you can’t compare it to other products on the shelf. The main issue is really the term “serving size”, as it implies that what’s in the package is a single “serving”. (And this confusion only applies to smaller, convenience size packages. Nobody would think a party size bag of chips is a single “serving”). If they called it something else, like “sample size”, it might not be so bad. However it’s also difficult to come up with a succinct word to describe it.
