Ok guys since Luffy cameback we saw people saying Luffy fully recover his health when eated.
Eating have a limited effect on Luffy.
When he heats and only under some conditions Luffy can recover and not entirely.
We will go with the most recent counter example
When Luffy finished to fight Katakuri he was hungry and in bad shape.
He had some time but didn't eat. We know that food were present in mirror world.
When he came back on the boat he didn't eat either.
In this case he slept.
Same thing after MF on rusukaina if I remember correctly, on W7, on Alabasta and in Thriller bark
Hence eating isn't enough he need to sleep and eat.
