i have yet another question!

granted i'm not riding far enough yet to warrant taking along power/snack bars (at least i don't think i am) but to prepare for my longer rides.. i would like to know the best/healthiest ones to eat.

i looked at and picked up a couple of kashi brand bars cuz i liked the ingredients list (not a ton of sugar, preservatives, nor unhealthy stuff)...

what do you all eat/recommend? and normally how far/long before you need them...

or do you not eat the bars but take other stuff (i.e. banana, nuts, etc)

again.. THANX!
