i bought a 1.5 L jug of grapefruit juice and a 3 L jug of orange juice at the same store at the same time. they're the same brand, even.

the amount of sugar, per serving, is the same - 21 or 22 g per 250 ml.

there is a warning on the orange juice, but not the grapefruit juice. why?

because the grapefruit is a 1.5 L jug and the orange juice is a 3 L jug, so the jug of orange juice has twice as much total sugar.

when labeling is this stupid, it creates ignorance and confusion. it does the opposite of what it's supposed to. frankly, i can read the ingredients, and i don't need a misleading label to confuse me. this system should be abolished outright.
