I agree completely (as do many others including the guys at Tacoma Mountain Rescue Unit) on the tea and my larger kits (the ones that actually include a metal container like a coffee can) now contain a couple bags of caffeine free/herbal tea for that very reason. I chose the caffeine free because I feel that stimulants are not wanted or needed in a survival situation... at least not for me. I haven't given much thought to the Power Bar concept, I guess since I live in a predominatly warm area. Although now with winter on the way, hypothermia prevention is a legitimate consideration even here.
