I like that food can be used to heal. It has the same flavor as Second Wind and represents refreshing yourself to regain your vigor.

What I don't like is a character eating a whole potato or melon during a 6 second round where they are also running, firing a longbow, and dodging enemy attacks. It's way beyond silly and breaks the suspension of disbelief. Plus, stuffing yourself in combat would LOWER your effective HP. Eating like that doesn't sound refreshing at all. XD
