eli5: if fruit is natural sugar, how do scientists determine how many grams of sugar it has? which sugar do they measure? table?

Question

im reading my pack of dates and it says two dates have 25 grams of sugar, but if i put that on a scale itll be almost bigger than the dates themselves. so I dont get it, same for all the other measurements too, like protein or fiber? how do they know/measure it all?

Answer 1

scientists use a standard weight of dates (say 500g) and then the package says “serving size 3 dates or per 500g”

not every date is the same size; and not every package has the same number or identical weight dates
