Don't bring and eat foods you are not accustomed to eating regularly. If you don't like cold pizza slices, don't eat cold pizza slices on your hike. Eating food you are not used to eating can or may cause major gastrointestinal problems.
In other words, don't experiment...but experience the grandeur!
A good rule to follow and I got this from Kurt Wedberg:
Pace, pace, pace...Nibble, nibble, nibble...HYDRATE, HYDRATE, HYDRATE!
And yet another: Co-"pee"-ous and clear...s"pee"ks volumes. You get the picture regarding hydration.
