Segmented health, hunger, and water bars

When you have a food item it tells you how much hunger it fills, percentage wise, I believe, but your hunger meter is just a solid bar, as are all the others. It would be great to be able to visually SEE how much of the bar the item will fill, like maybe section it off into 5 or 10 sections, and instead of saying the Potato thing fills 15% or whatever, it'll fill 1 slot or half a slot, that way we'll have a better understanding of just how much the Items will fill up or take away from our hunger, health, or thirst meters. This way in not wasting my items trying to keep myself topped off, not knowing just how much of my meter this item will fill. I feel like this is a fairly normal thing most games employ.
