A few weeks ago I was at work (5:00pm to 1:30am shift at the hospital) and was feeling that I needed a little treat at about 11pm or 12am for my break. On this particular night I was thinking a little box of junior mints (the snack size) that they have in the cafeteria for .15. Once I got there I saw a nurse with a apple and made the comment that it looked much healthier than what I was going for. So I decided to try the apple instead. The results were amazing! I wasn't dying at the end of my shift and made it through quite well. Usually I'm dead tired. Thinking that was no coincidence, the next time I worked I made sure to take a apple with me for that late night snack. And again, my energy was boosted. I mentioned this to a friend a few days later and she said, "Yeah, I heard a apple was equivelant to a cup of coffee."
So I looked it up on the internet and found this on eHow.com:
Eat an apple in the morning instead of drinking a cup of coffee. An apple can actually energize you naturally in the same way that a regular cop of coffee will and is a much more healthy alternative.
