you're right, that would be suicide!
if you enabled the hunting-skill, you are able to hunt little animal like rabbits or chickens. just stand richt next to them (as near as possible) and rightclick them then. if you have 2*2 space in your inventory, you have it their.
then you wring neck+butcher it, using a campfire to roast the meat
alternativly, you can search for light forest (lighter green on minimap) where apple trees grow (+you find there hazelnuts and the chickens mentioned above)
when you enabled foraging and got your exploration a little higher than 1, you are also able to find spindly taproots on ground.
you can pick them by righklicking and use them either for food or as string, used for some structures or as fishing-line
edited, thanks Ariki . my mind wasn't about mines, i just don't distinguish any more

(crap i get 90lp for picking, i am dropping it afterwards)
