Certain skills will drain less stamina when you level them and I notice the "fruit" resources give you more Stamina than Health. So if I'm doing a lot of harvesting and running around I "fruit" up more, If I fight a lot (esp at night) I "meat" up. :)

I haven't played far enough in this update to see the recipes for meat based meals and fruit/veg meals yet to see if this Health and Stamina differences are.
