i live in canada, so i don't know how it works in some other places, but i assume it's similar
on the back of any food product you have your nutritional information (say, bag of chips)... next to some of the items in the chart, like carbohydrates or sodium, you have a percentage, which is like the amount of that particular item you're supposed to have in a day (ex. chips have 15% sodium so it's 15% of the total sodium you need in a day)
my question is
how do they know what 100% is? a five year old girl doesn't need the same amount of sodium (as an example) as 250 pound man?
what's the average "human size" i guess...?
