i think food items can retain a lot more energy than other things, it's just getting that energy back out isn't efficient.

No, it's efficient, you can even burn food for energy. Actual fuels like gasoline and coal store even more energy though, and they're much cheaper. Electricity kills because it's focused. It can burn stuff in less than second, and can disrupt vital muscle functions.
