For a quick fix of energy, whole unprocessed foods always trump packaged ones. But a great organic apple or just-ripe banana isn't always available when you need it. That's when energy bars can save the day. Just make sure to choose the most natural form you can find (Sadie liks Luna, Kind, and Pure brands), with the least amount of processing, sugar, and fats. Or whip up your own energy bar for even more wholesome nourishment the next time hunger strikes.
